    - Setting variables on Parent form Hi, I have a Parent form (lets call it Payment) that has allowed a user to open a search form (lets call it Search). I use ShowDialog to open the Search, then the user enteres a string and clicks the search button. Once a selection has been made from the results, I need to send the selected value back to the Payment form and have it reload with the applicable data. How do I send the selected value back to the Payment form I have a public variable set up in the class: namespace PaymentsRemittance { public partial class frmPayments : Form { // Global Parameters // The variable below is the one that needs to be set by the users selection on the search page. public string strEftid = "" ; public frmPayments() { InitializeComponent(); //TODO: Get this working on deployment. try { ApplicationDeployment ad = ApplicationDeployment .CurrentDeployment; string str = ad.ActivationUri.ToString(); } catch { } } However I dont know how to set this value from the child dialog (Search). Can someone please shed some light on this for me cheers Tag: Windows Forms Data Controls and Databinding How to make a DataGridViewCheckBoxCell invisible in a visible column (or row) Windows Forms

    - [MSI] - Only deploy a file if it doesn't exist! Hi all I'm needing some advice with deployment projects. I've created a "Custom Folder" that is named "Config" and the Path is "C:\Config". So I add a file to this folder and when I install the package, the installation puts the file in the correct path! Fine! But... when I change the installer's version (increasing) to install an updated assembly, the installer "overrides" the config file that was in the config folder, "reseting" my configuration.... So.. I need to deploy the config file ONLY if there is no file in the folder already. Otherwise I'll lose the configurations made after the first installation... How can I deploy the file only if it does not exist in the specified folder Thanks!

    - Error installing Winforms 2.0 application with ClickOnce deployment Hi. I have an Winforms 2.0 application that I want to deploy using ClickOnce deployment. I have tried it and the deployment seems to work. I get the webpage where I can install the application from, but when I try installing the application I get an Windows error dialog and a '.NET Runtime 2.0 Error Reporting' entry in my Windows eventlog. Detailed error message: EventType clr20r3, P1 app.exe, P2 1.0.2211.28810, P3 43d0fb04, P4 mscorlib, P5 2.0.0.0, P6 4333ab80, P7 32f8, P8 d8, P9 system.io.filenotfoundexception, P10 NIL. I publish the project to a server within the network I'm on, and the error occurs when I try to install from the generated ClickOnce website from my laptop. Does anyone know what could cause this error I wish it would say which file is missing! UPDATE : I found that the application seems to have been installed on my laptop, but when I try to run it, I get the error described above. Thanks!

    - How can we achieve Scroll lock type functionality in text box Or Richtextbox (c#) I have a multiline textbox/RTB where text is appended every 20 ms. I want to copy some text in between and see what i have received. But whenever I click on RTB, It scrolls to down and I am not able to copy related text.

    - ClickOnce and MSI together. Following the steps mentioned in http://msdn2.microsoft.com/en-us/library/ms973805.aspx#clickoncevsinstaller_topic8 I am able to deploy the windows application using both the technology together. But I have following doubts: 1. How can I auto run the InternetShortcut Url file in MSI, on account of any changes occured to it. I mean if there is change in version (Updation). --- I want to implement the advantages of clickonce through this file as it is pointing to clickonce publish.htm file only. 2. After the installation of application (using modified .msi in ORCA), we get a Internetshortcut url file in the target folder on the client m/c. If we run this internet shortcut url file manually it does open the publish.htm. And from this page when we click on the Install button, it creates (Installs) another instance of the application! --- I don't want to create another instance of the application, it should just install the updates if there is any. Am I skipping any settings in MSI to achieve this Please help me. It would be really appreciated if anybody can give me step by step procedure to combine the best features of MSI and clickonce together. Looking forward to lightening fast responses to this query. Thanks in advance! Tag: Windows Forms Data Controls and Databinding How to make a DataGridViewCheckBoxCell invisible in a visible column (or row) Windows Forms

    - DecimalTextBox sample I downloaded the DecimalTextBox control sample from http://download.microsoft.com/download/0/8/7/087e6a47-7306-4a5c-ad97-d1ffd58d712e/DecimalTextBox.msi . I would really like to use this. Unfortunately the code does not work, at least in VS2005SP1. The sample app runs, but when you click the "Commit" button it throws an exception. I get the same exception when I try to place a DecimalTextBox on a form in my own application. Does anyone have a working version of this control for .NET 2.0 Edit: I got the demo app to work by entering a valid value into the plain textbox before clicking Commit. However, the control cannot be used in an application via the Designer because the Designer (apparently) attempts to initialize the control's Text property with an empty string, which throws an exception. If I can get it to work I'll post here. Tag: Windows Forms Data Controls and Databinding How to make a DataGridViewCheckBoxCell invisible in a visible column (or row) Windows Forms

    - VS2005 DataGridView I'm using databound DataGridViews in VS2005(VB) and would like to have the following features that are available in an Excel Worksheet: 1. Add one of an unknown number of columns at run-time for the user to name (header) and insert data; save to the database. Would it be correct to think that the only way to do this is to create a reservoir of additional columns for this purpose in the corresponding Database Table at design time and make a column visible when requested by the user at run-time I can stipulate the type of data that can be entered. 2. Insert an additional row at run-time at a user selected location in the DataGridView, insert data, save to the database and on re-loading have the DataGridView display the row in the location where it was inserted by the user. When I do this now, InsertRow assigns the next ID to the new row and on reload displays it as the last row in the DataGridView. I've tried using an additional (hidden) column to keep track of the row order but it proved more difficult than I expected, and if I ever AutoSort the rows, unpredictable (to me) sorting persists with AutoSort off when I try to re-establish the row order identified by integers in my tracking column. Should I try working without Identity Auto Increment and manipulate the row IDs programmatically or will I encounter similar or other problems 3. Copy/Paste multiple rows of data with user-selected numbers of columns from within the DataGridView or from Excel to the DataGridView, using Ctrl-C and Ctrl-V via the Clipboard. I can do this one row at a time using the DataGridView_KeyDown event handler for e.KeyCode=Keys.V and Split(Clipboard.GetText, Chr(9),-1) where the number of columns is counted by Split.Length -- Code attached. But for multiple rows I can't create a satisfactory end-of-row identifier, Chr(9) is not trapped by the usual String functions and is not an unambiguous end-of-row identifier. Is what I want to do impossible unless the number of columns being pasted is known at design-time Have I missed something in the methods provided with DataGridView and DataTable Are there plans for MSFT to provide Excel-type facilities in VS2005 DataGridView or should I resort to driving Excel from VS2005 - how In my Form: Private Sub RmScheduleDataGridView_KeyDown( ByVal sender As Object , ByVal e As System.Windows.Forms.KeyEventArgs) Handles RmScheduleDataGridView.KeyDown 'paste a single row from an excel spreadsheet (via Clipboard) or from the Datagrid via clipboard Dim dgv As DataGridView = Me .RmScheduleDataGridView Dim kmod As System.Windows.Forms.Keys = e.Modifiers Dim kcode As System.Windows.Forms.Keys = e.KeyCode Module1.KeyCopyPaste(dgv, kmod, kcode) End Sub In Module 1: Public Sub KeyCopyPaste( ByVal dgv As DataGridView, ByVal kmod As System.Windows.Forms.Keys, _ ByVal kcode As System.Windows.Forms.Keys) 'paste a SINGLE row from an excel spreadsheet or from the Datagrid (both via clipboard) If dgv.EditMode = DataGridViewEditMode.EditOnKeystroke Then Dim s As Integer = dgv.GetCellCount _(DataGridViewElementStates.Selected) 'selectedCellCount Dim a As String = My .Computer.Clipboard.GetText Dim Excel As Boolean = False If a <> "" Then If kmod = Keys.Control Then If kcode = Keys.V Then Dim i As Integer = 0, j As Integer = 0 'rows, columns Dim r As Integer = 0, c As Integer = 0 If My .Computer.Clipboard.ContainsText _(TextDataFormat.Rtf) Then 'from Excel sheet, RichTextFormat a = Mid(a, 1, a.Length -2) 'strip trailing double chr(9) Excel = True End If Dim bc() As String = Split(a, Chr(9), -1) Dim cm As Integer = bc.Length - 1 'number of columns If s = 1 Then r = dgv.SelectedCells(0).RowIndex c = dgv.SelectedCells(0).ColumnIndex Dim nv As Integer = 0 Dim jv As Integer = 0 For j = 0 To cm jv = j + nv Dim cv As Boolean = dgv.Columns(c + jv).Visible Do While cv = False 'skip invisible columns in DataGridView nv += 1 jv = j + nv cv = dgv.Columns(c + jv).Visible Loop Dim va As Type = dgv.Columns(c + jv).ValueType Dim van As String = va.Name If van = "Integer" Then 'requires integer dgv.Rows(r).Cells(c + jv).Value = Int(Val(bc(j))) Else dgv.Rows(r).Cells(c + jv).Value = bc(j) Dim x = dgv.Rows(r).Cells(c + jv).Value End If Next j End If End If End If End If End If End Sub Tag: Windows Forms Data Controls and Databinding How to make a DataGridViewCheckBoxCell invisible in a visible column (or row) Windows Forms

    - Disable RenderMode selection on my custom ToolStrip I have subclassed the ToolStrip control which I called MyToolStrip and ToolStripProfessinalRenderer which I called MyToolStripProfessionalRenderer. To make my custom ToolStrip control use my custom renderer I've add the following line to the constructor of MyToolStrip, like this: Code Snippet internal class MyToolStrip : ToolStrip { public MyToolStrip() { this.Renderer = new MyToolStripProfessionalRenderer(); } } However, doing it like this, doesn't prevent anyone from changing the renderer in run-time after the constructor is called. So, I want to prevent this from happening, I want my custom renderer to always be the renderer selected on MyToolStrip. How can I do this and how can I hide the property "RenderMode" from the properties list in the Visual Designer when a ToolStrip (or my custom ToolStrip) is selected Tag: Windows Forms Data Controls and Databinding How to make a DataGridViewCheckBoxCell invisible in a visible column (or row) Windows Forms

    - DataGrid help Hello Friends, I need your help setting up a DataGrid. I have this DataGrid, and I want the following options to be available on it, some I got working, and some only work if I disable another option. How can I get all of these options to be available on my DataGrid 1) I want to be able to select a single line, or multiple lines. This by clicking on one cell in the row. I want it to become blue, like when selecting text. If I click control or shift, it will select multiple rows. This in order to remove rows from the grid. 2) I want to be able to sort the list by a specific coloumn in it. 3) I want the height of the row to be determined by the amount of text inside it. thus if the text in a specific cell in a row takes a bigger space than the default row height, that row's height will be enlarged. Imagine this situation on a Word's table; if you enter a big amount of text in a cell, that entire row's height enlarges. 4) Something I don't want - when you click on a cell, the text inside it becomes blue (only in that specific cell) and its format is changed. e.g if I have: "This is a Nice line" if I click on it it becomes blue and the text becomes "This is aNice line" I never want the text's format to change. The problems I have: if I "enable=false" the DataGrid, I get no event for a click on it thus I can't select it (i.e turn it blue). I'm very sorry for this over-sized message and I would really appreciate your help.

    - treeview - shift key - select multi nodes in same level Mikael Wiberg has a C# code example on MultiSelect in the Treeview. He recommends that the BeforeSelect event be used. I see that when I select a node, the canceleventargs in the BeforeSelect event tell me the nodes index and level along with the parents index and level. I am employing the DrawNode method as per Hans Passant's suggestion as I need to display a custom backcolor in the rectangle for each text, other than the default select blue. With the sole requirement that the user be able to select a node at a specific level, level 2, and then when they hold down the shift key and then select the next node which will then define the range of nodes that need to be selected..... how do I do that By creating an array I seem to recall that Mikael said that Selnode property needs to be used rather than SelectedNode property. I am not sure what that means yet. Thanks, -Greg Tag: Windows Forms Data Controls and Databinding How to make a DataGridViewCheckBoxCell invisible in a visible column (or row) Windows Forms

    - Textbox scrolling When I use textbox.appendtext(buff), buff is successfully appended to the textbox and the textbox automatically scrolls. However, there seems to be a limit... the scrolling stops (as does the data being appended) after a certain amount of data is appended. I have the maxlength set to 0 and have also tried setting it to 1,000,000. I have resorted to: textbox.text+=buff textbox.selectionstart=txtbox..text.length textbox.scrolltocaret() Unfortunately, that scrolls the text all the way to the beginning and then back to the end everytime which causes undesirable flashing. Does anyone know why the appendtext method is limited Tag: Windows Forms Data Controls and Databinding How to make a DataGridViewCheckBoxCell invisible in a visible column (or row) Windows Forms

    - Splitter Distance Error Hi there, I am getting a strange error with my SplitContainer when trying to manually set the SplitterDistance value. The SplitContainer.Orientation is set to Orientation.Horizontal, the SplitContainer.Panel1MinSize is set to 25, the SplitContainer.Width is set to 150, and the SplitContainer.Panel2MinSize is set to 25. When I try to set the SplitContainer.SplitterDistance value to 100, I get an error saying "SplitterDistance must be between Panel1MinSize and Width - Panel2MinSize". However, I am doing just that. Any ideas why I am getting this error message The exception message is of type InvalidOperationException. According to my MSDN this exception means "The value is incompatiable with the orientation". However, MSDN specfically states that SplitterDistance is valid for use with both the Orientation.Horizontal and Orientation.Vertical values. Also, I should note that I only get this error message when I try to manually set the SplitterDistance value after having added the SplitContainer to another Control. If I set the SplitterDistance value before adding the SplitContainer to the parent Control, I don't get the error message. However, the SplitterDistance value doesn't actually change either. Any help would be appreciated. Thank you Tag: Windows Forms Data Controls and Databinding How to make a DataGridViewCheckBoxCell invisible in a visible column (or row) Windows Forms

    - Controls unregistering their own events Hi, I have a memory leak problems that is resolved by either nullifying the datasource or unregistering the events of a Combobox. Nullifying the datasource might trigger events so I'd rather not use that solution. I could -= all the events of all my controls but what's I'd rather have is a way for the components to unregister their own events and since they don't know which ones were registered, I can't use the -= with explicite events. the controls have a EventHandleList call Events but it doesn't really work like other collections (can't really loop on it). Events.Dispose() method doesn't do the job either, the leak is still there so I presume that the events aren't really unregisted. So, What I'd like to know is if there is a way to loop thru all the registered events to unregister them I looked at the help for EventHandlerList since it is the type of Events property and it lists a public property named Item as being the delegate list but strangely, there is no such property in Events, not even hidden; obviously, the help is wrong or is it is there a way to expose that property Thanks Tag: Windows Forms Data Controls and Databinding How to make a DataGridViewCheckBoxCell invisible in a visible column (or row) Windows Forms

    - Hide method doesn't work on program's first execution Hi there.

Ok, I close the application and then run it again. This time frmMain hides correctly and frmLogin is the only form that is visible.

    - File verification I am trying to verify that some files on a hard drive are also listed in a database, and that file names listed in a database are also on the hard drive. I want to know if there's a more efficient way than what I'm doing. The files are divided randomly into some folders (so not to kill windows with millions( ) of files per folder). The files are stored like this Mainfolder __12345 __23456 __34567 Each folder location is stored in the db with the filename. So, I've opened a connection to the DB and am using a SqlDataReader to get a list of the folder names in the main folder. Then, I am using a FileInfo[] to store the file names of the first subfolder in the SqlDataReader. To verify both ways, I am looping through the FileInfo[] to get the filename(if i have a file name, I'm assuming the file exists, duh). Each iteration of the loop then opens an additional connection and datareader to check if the current filename exists in the db. Then closes the SqlConnection and the SqlDataReader in the loop before the next iteration. it just seems like I'm opening and closing a lot of connections, is that a problem Tag: Windows Forms Data Controls and Databinding How to make a DataGridViewCheckBoxCell invisible in a visible column (or row) Windows Forms

    - Form controls reorder on show Hi everyone, I have a baseform which has 3 controls (a Panel, a splitter and a UserControl) that add to the form's Controls collection. I inherit from this form and add some controls to Panel (not directly to the form's Controls collection). The 3 base controls are docked such that the usercontrol and the splitter are on the right and the panel fills the remaining space. Obviously I want the splitter between the Panel and the usercontrol, which is what shows at design time, however I found at runtime the splitter is on the far right with the usercontrol to the left (making the splitter useless). Debugging this I find that the form's controls collection reorders itself when the form is told to show. Has anyone else experienced this and have any information as to what is causing the controls collection to re-order. I don't want to constantly check the control order when I call show. Thanks, Mark.

    - DataGridViewComboBoxColumn - Display vs. Actual (data) value Hi All, Is there a way to specify display value and actual (data) value for a DataGridViewComboBoxColumn For example, my database table has a column account_type of type NCHAR(1), which is used to store either 'C' for Credit or 'D' for debit. When the data records are retrieved from the table and displayed on a DataGridViewComboBoxColumn cell, I want it to be displayed as "Credit" or "Debit" respectively. Vise-versa, when users add a new record, they should be able to select Credit or Debit from the combo box, but the actual data to be saved should be 'C' or 'D' respectively.

    - Strange problem with DataGridViewComboBoxCell Greetings, I am constructing a user interface that uses the tab control with two tab pages. Both have DataGridViews that are bound when the user loads an object and both have contain a column with the DataGridViewComboBoxCell that are bound with child/parent related binding sources. If I load dataset and Databind to both DGVs, the one displayed on the first tab page shows fine. When I click on the second tab page, I get an error that the "DataGridViewComboBoxCell value is not valid". However, if I click on the second tab before it is bound to any data (thus painting the control) then load the dataset and bind the controls, I do not get the error. The problem seems to be related to the DataGridViewComboBoxCell because when I replace the column with a Text Cell, the application works fine. Has anyone experienced this problem Many thanks in advance for any insights.

    - Hyperlink in Datagrids Hi I have a windows application coded using Visual C# in .NET 2005. The application queries data stored in an MS Access table. One of the field in the access table contains text which is hyperlinked to particular files on the local machine. Say, I have a field called TITLE and all each of the specific documents (pdf or word) are hyperlinked to the corresponding record in the TITLE field. I am able to do this in Acess. But, this property does not carry over in the windows application. I am using a datagrid to display the queried results. I set the required field to be as "Hyperlink" property for the datagrid and still the file does not open.

Hi,

I am trying to put a blank cell instead of a checkBoxCell in a DataGridView were all columns are CheckBoxColumns.
I don't want to make the whole Row or Column invisible, just a certain cell where "i don't want a checkbox to appear".

Now, I tried to make the designated cell invisible, but it seems that the visible property for Cells is ReadOnly.

If you require further clarification of the situation, please don't hesitate to ask.

I appreciate the help.

Regards,
