    - Minimize MDI child forms Hi Krunal, If I understand your query correctly it can be split into two parts: Firstly you would like to minimize all the child windows on your MDI Parent for which you can use the solution provided by Chunsheng Tang or humble.apprentice above. I will try to answer the second part of your question i.e on how to create the effect of minimizing the windows to the MDI's status bar as minimized windows appear on the windows task bar. .Net does not provide this feature by default and will require you to do some coding for the same. Here's what I can suggest: 1) Drag and drop a StatusStrip control on your MDI parent window. This is the control which will hold your minimized windows (or atleast create the effect of holding the windows). 2) Create a public function in the MDI window class as follows: public void MinimizeWindowsOnStausBar(Form childForm) { //create an instance of a ToolStripButton which will give the effect of a window minimized in the StatusBar. ToolStripButton tsb = new ToolStripButton(childForm.Text); //use the Tag property of the ToolStripButton to hold the reference to the child window which is being minimized //as this reference will be used later to maximize the window when clicked in the status bar. tsb.Tag = childForm; //optionally set the backcolor of the ToolStripButton to give it the look and feel of the XP theme tsb.BackColor = Color.Blue; //assign an event handler for the button. The event handler provided here will be called when the user will click //the window name in the status bar. tsb.Click += new EventHandler(tsb_Click); //hide the form that is being minimized. childForm.Visible = false; //add the newly created button to the Status Strip control added to the MDI Parent in step 1 above. statusStrip1.Items.Add(tsb); } //event handler function that will handle the tsb.Click event as assigned above. void tsb_Click(object sender, EventArgs e) { ToolStripButton tsb; //Typecast the sender object to ToolStripButton as the sender is always going to be a ToolStripButton. tsb = (ToolStripButton)sender; Form childForm; //retrieve the chilform object from the Tag property of the ToolStripButton. This Tag property was initialized in //the MinimizeWindowsOnStausBar function. childForm = (Form)tsb.Tag; childForm.WindowState = FormWindowState.Normal; //make the window visible. childForm.Visible = true; //remove the button representing the minimized window as the window is no longer minimized. statusStrip1.Items.Remove(tsb); } 3) Now we need to make calls to the MinimizeWindowsOnStausBar function whenever a child window is minimized. For this I have placed code in the Resize event handler of each of the child forms. I am sure you can optimize it further by using a more generic approach. But for now you can place the following code in the Resize event handler of each of the Child forms. private void Child1_Resize(object sender, EventArgs e) { //check if the child form has been resized and is visible so that the code only executes when the child form is //being minimized. if (this.WindowState == FormWindowState.Minimized && this.Visible) { //Form1 is the MDI Parent form. You should replace this with the name of your MDI Parent form. Form1 frmMain; //typecast the MDIParent of the child form that is being minimized so that we can call the //MinimizeWindowsOnStausBar function on the MDI Parent. frmMain = (Form1)this.MdiParent; //Call the MinimizeWindowsOnStausBar function which will create the effect of window being minimized onto the //status bar. frmMain.MinimizeWindowsOnStausBar(this); } } This is a very quick solution to your problem and I would recommend you to optimize or modify the code as per your need. I hope this solution would be of some help to you. Cheers Sharad Tag: Windows Forms Sample Applications My Form-Designer doesnt work anymore! Windows Forms

    - Programmatically Changing Control Properties Many thanks to both Brendan Grant and KJacquemin for lightening fast replies. 1. You are right, there is no ErrorProvider 2. Both answers look pretty good to me with KJacquemin's being slightly simpler. I've gone for the first answer because I don't need to add the field name into the tag field. Many thanks, Doug Tag: Windows Forms Sample Applications My Form-Designer doesnt work anymore! Windows Forms

    - AutoScroll question thanks nobugz, i the use of the panels was to get the scroll bars to appear. i later saw the min scroll size as you indicated. and i do understand what you showed me. unfortunately, it will not be so simple as offsetting all of the virtual objects. certain objects being moved can have an effect on others and is costly if many are moved, there are lots of hand calculated beziers, weird regions and paths being used. i have a nearly working solution going right now using manual scroll (if you can call it that). thanks, scott Tag: Windows Forms Sample Applications My Form-Designer doesnt work anymore!

    - Two Binding Navigators on a Single Form? Hello. I've been trying to create a tiny application which will access a certain MS Access database and supply interfaces for editing and viewing the data on it. I attempted to use a tabbed interface for no particular reason. Every tab will contain text fields and other input tools to recieve or view data of a particular table. I add my data source, change the table to 'Details', change the fields to what I want them to be where text fields would be cumbersome, and finally drag it to the first tab. The DataSet, BindingSource, TableAdapter and BindingNavigator are successfully added to the form and the fields are visible. After making the necessary formatting changes, I loaded the other tab, and attempted to do the same things for another table. Here is the problem: A Binding Navigator did not appear this time. The fields and labels successfully appear and the related code is added to the designer, however without a Binding Navigator they are useless. I am using .NET 2.0, and Visual Basic Express. The cause of this problem seems to be trying to use more than one table on a single form. Will I have to give up on the tabbed interface and use buttons (or a similar interface) to switch forms instead, or is there a workaround which does not involve coding in a BindingNavigator manually I will, if I must, however I'd like to see a tutorial on applying a BindingNavigator if that is your suggestion. Thanks in advance for the responses, Nameroc Tag: Windows Forms Sample Applications My Form-Designer doesnt work anymore! Windows Forms

    - display ascii art in a textbox or richtextbox or whatever? hi, i'm trying to write a program with C#. it should display ascii art. i tried to read in a ascii-art-file and display it in a textbox. first problem, the encoding... it replaced the special chars with questionmarks, i solved this by using Encoding.Default. works well, if i save the text in the textbox back to a file and open it in windows editor everything is fine. now my problem is: those special ascii chars (above 127) are not displayed correctly in the textbox. instead of a black box as it should be i get Os or Us and so on... i already tried different fonts (Lucida Console, Lucida Console ASCII, MSI Console,...) but all with the same result i don't know how to fix this any ideas Gr33tz Tag: Windows Forms Sample Applications My Form-Designer doesnt work anymore!

    - RichTextBox AutoWordSelection bug There seems to be a bug with the AutoWordSelection property in the RichTextBox control in .Net 2005; it doesn't seem to take effect at all. Even if the property is set to False, the whole word still gets selected when the user drags across a line. Is there any way to work around this I thought of making a call to the control using the SendMessage Win32 API, but couldn't figure out what value to pass in for the 'msg' parameter.

    - Heavy operation and Windows.Forms.Timer I have to display a time synchronized with my server application. I use SNTP client to get a time from the server and display that time using timer. I resynchronize each 2 minutes. I thought that .NET design and development team had something in mind for situations like this one when did designing of the .NET. I see two solutions for my problem: 1. I resynchronize after each Loading/Saving operation if it takes longer than a second. This is a suggeted absolute time measure approach. I can use Environment.TickCount and TimeSpan.TicksPerSecond or DateTime.Now. 2. I run Loading/Saving operation in another thread. The main UI thread will open an invisible modal dialog which will wait for the operation to complete ( still do not know to do it) and then closes itself. What is a "right" way to do i do not know. I like more the second way, but do not know how without blocking/sleeping in UI thread get a notification from another thread. I do not like idea of events but it looks like a single option.

    - Partially Colour DataGridViewRow Right here's the situation: I've developed an application which is an electronic shift log for the company I'm working for. At each shift the shop floor guys use my application to log events that happen (various details plus an input time). I use the input time to calculate the duration of each event and I have a total duration for the entire shift. The datagridview displays a single shift with several rows in it (which the duration and total duration have be calculated). What I want to know is if it's possible to partially colour a row depending on what percentage of time it takes up. I.E. Lets say that I have 3 rows in this shift. Row 1: Duration 2 hours Row 2: Duration 3 hours Row 3: Duration 5 hours. Which gives me a total duration of 10 hours. How would I colour the 20% of the first row, 30% of the second and 50% of the third So pretty much it looks like a strange bar chart/progress bar. I have talked about using an actual progress bar in the datagridview but its not what the managers want.

    - Need Help With SendKey Function Hi All, I am a new Visual Studios user and new C# programmer. Currently I am trying to figure out a way to automate a program install (hitting Next buttons, and then Finish basically) by the way of SendKeys, but I am running into problems. Right the program brings the install window to the foreground and sometimes sends the Enter key correctly. Not really sure why it only works sometimes, other times it does nothing. The big problem is that after the Enter key is sent it moves onto the next part of the installation, and none of my further keys get sent correctly. I thought it was a timing problem so I tried to insert a for loop in order to delay the code execution for a bit...didn't work either. Here is my code so far: Code Snippet using System; using System.Runtime.InteropServices; using System.Drawing; using System.Windows.Forms; namespace SimulateKeyPress { class Form1 : Form { private Button button1 = new Button (); [ STAThread ] public static void Main() { Application .EnableVisualStyles(); Application .Run( new Form1 ()); } public Form1() { button1.Location = new Point (10, 10); button1.TabIndex = 0; button1.Text = "Click to Automate Install" ; button1.AutoSize = true ; button1.Click += new EventHandler (button1_Click); this .DoubleClick += new EventHandler (Form1_DoubleClick); this .Controls.Add(button1); } // Get a handle to an application window. [ DllImport ( "USER32.DLL" )] public static extern IntPtr FindWindow( string lpClassName, string lpWindowName); // Activate an application window. [ DllImport ( "USER32.DLL" )] public static extern bool SetForegroundWindow( IntPtr hWnd); // Send a series of key presses to the Install application. private void button1_Click( object sender, EventArgs e) { // Get a handle to the Install application. The window class // and window name were obtained using the Spy++ tool. IntPtr InstallHandle = FindWindow( "InstallShield_Win" , "CYMDIST 4.5 Rev 15" ); // Verify that Calculator is a running process. if (InstallHandle == IntPtr .Zero) { MessageBox .Show( "Calculator is not running." ); return ; } //SetForegroundWindow(InstallHandle); IntPtr InstallHandle2 = FindWindow( "#32770" , "CYMDIST 4.5 Rev 15" ); // Make Install the foreground application and send it // a set of instructions. SetForegroundWindow(InstallHandle2); //SendKeys.SendWait("{TAB}"); SendKeys .SendWait( "~" ); for ( int i = 0; i == 100000000; i++); SendKeys .SendWait( "~" ); SendKeys.SendWait("~"); } // Send a key to the button when the user double-clicks anywhere // on the form. private void Form1_DoubleClick( object sender, EventArgs e) { // Send the enter key to the button, which raises the click // event for the button. This works because the tab stop of // the button is 0. SendKeys .Send( "{ENTER}" ); } } } Any help is appreciated. Thanks! Tag: Windows Forms Sample Applications My Form-Designer doesnt work anymore!

    - Designer can't find my class? EDIT: I installed VCSE SP1 and haven't had any trouble since, it looks like this might have been an old bug because there was a hotfix (presumably included in the service pack) whose description sounded like my problem. Hello, I'm working on a windows forms app using the designer in VCSE. Everything was working fine for a while, but then one time I tried to build+run and got a MethodNotFoundException: for some reason it could not find a method I was calling, even though the build has no problems, and the class' interface guarantees the method exists. I restarted VCSE and now I get this error in the designer window: "Could not find type 'CharacterEditor.CharacterView'. Please make sure that the assembly that contains this type is referenced. If this type is a part of your development project, make sure that the project has been successfully built. The variable 'characterView' is either undeclared or was never assigned." But the class does exist, the application builds properly and has functioned using this class before, it's just that for some reason it's unable to find it at runtime I guess. I have no clue what's really going on, this happened suddenly and I don't think I was even making changes to the editor or the control that it can't find at the time. Anybody have an idea what could be wrong Thanks, max Tag: Windows Forms Sample Applications My Form-Designer doesnt work anymore! Windows Forms

    - Inserting records not working...2 DGVs, Master/Detail, ForeignKeyConstraint, bound to 1 dataset (2 tables) Hi All, I have 1 dataset with 2 tables with one foreign key constraint relation defined between the tables. I have a form w/ two DGVs (a master and a child). The DGVs are bound with binding sources to the dataset. Everything works EXCEPT, if I add a record to the parent DGV, then add related records to the child prior to committing the parent to the data store. i.e. * add a record to the parent *add related records to the child *save the data: parentTableAdapter.update, childTableAdapter.Update. the problem is that when the parent is committed, the newly obtained record ID is not being propagated to the related child records and I get a foreignkeyconstraint violation exception. However, If I save the parent before adding the child records, then everything works fine. I noticed that a temporary record ID rather than a real record ID is created for the parent record prior to being committed to the data store. If I don't save the parent, then the temporary key is propagated to the child records. But when I update the parent table, and the parent record gets it's real record ID, it's not propagated to the child table. Is there a way to make this work I want users to be able to add parent records and child records without forcing them to save the parent records first.

Every now and then my userControls cause an error that looks like this. I'm not sure if its the same one, but the solution has always been to Build > Rebuild Solution. Make sure you close all your Designer windows before rebuilding.
