- Automatic update works when turned off Hi James, Thanks for your response, but I do infact use the CheckForDetailedUpdate method and not the async version. Sorry for not clarifying that. Once that returns I then ask the user if they wish to update (unless of course the minimum required version is set) and if they decline, I continue with my application startup. The problem then occurs the next time the application is started at which point the ClickOnce framework asks the user if they wish to update even though the automatic updates has been turned off. -Jari Tag: Windows Forms Data Controls and Databinding display member of checkedlistbox Windows Forms

- Disable button onclick to prevent multiple submissions Hi All, I have an upload form that successfully emails an attachment in an email. Once the user hits submit, I want the button to be disabled but the form to still do all the client-side validation and the server-side code to email the form etc. Is there a 'quick and dirty' method to achieve this Regards, Brett Tag: Windows Forms Data Controls and Databinding display member of checkedlistbox Windows Forms

- Sending Email when Exception I wouldn't recommend that you rely on that the application can send you an email when it fails in an unhandled way by handling the Application.ThreadException event. There might be a very good reason that your application fails and trying to send a mail might cause more trouble. This is probably not that likely but it is possible. Try to keep logging of critical situations to the minimum and use resources that are least likely to fail (like eventlog or files) to log unhandled exceptions. You can then monitor the event log or file for failures and have monitoring software act on it rather than you having to implement it into your application.. A possible scenario is if you have an unhandled network failure, you will most likely not be able to fire of an email from inside your application if it also relies on a working network connection.

- DataGridView - I need a simple example that works with List<??> Hello, I'm hoping someone can help me out here. I want to get started using DataGridView, but I've not actually managed to find any examples that fit what I'm trying to do. What I want to do is very simple: (1) I have a list of class instances thus: List<MyClass> classList = new List<MyClass>(); classList.Add(new MyClass("Fred")); classList.Add(new MyClass("Wilma")); (2) I want each MyClass member of classList to be represented as a row in my DataGridView (3) I want to show only a subset of the class parameters, for example: public class MyClass { private string name; private int anumber; // Want to show this in the interface public String Name { get { return (name); } set { name = value; } } // I DON'T want to show this in the interface public int Number { get { return (anumber); } set { anumber= value; } } } I think that sums it up. No SQL, nothing just a nice list of data that I want to display. Can anyone help Many thanks. I've attempted to find what I want from the FAQ, but I'm finding it hard to see the wood for the trees.. If I had a small example, I think I'd be better placed to understand what I need. Many thanks! Tag: Windows Forms Data Controls and Databinding display member of checkedlistbox Windows Forms

- Single click acting as double click in form designer I've been having the exact same problem too. I'm not certain, but I believe it began happening when I upgraded to SP1. It doesn't happen all the time. I haven't been able to come up with a correlation between number of files open, number of projects in the solution, number of forms open, or anything like that. I can't reproduce it right now. The way it always happens for me is if the form designer doesn't have focus, and then I click on the form designer or a control on the form. If the designer already has focus, the problem doesn't occur. Tag: Windows Forms Data Controls and Databinding display member of checkedlistbox Windows Forms

- Smooth Scrolling and the mysteries of OnPaint Hi, akeshet, Based on my understanding, you want to make a smooth scrolling panel, don't you I think you should not change the OnPaint method, but do that job in OnScroll method. For example, Code Block public class SmoothAutoscrollPanel : Panel { protected override void OnScroll( ScrollEventArgs se) { if (se.ScrollOrientation == ScrollOrientation .VerticalScroll) { this .VerticalScroll.Value = se.NewValue; } else if (se.ScrollOrientation == ScrollOrientation .HorizontalScroll) { this .HorizontalScroll.Value = se.NewValue; } } } In fact, in the panel's OnPaint method, you can only deal with the drawings for the panel itself. All the controls on the panel draw themselves in their own OnPaint method (Or even drawn by Win32 API). May this solve your second question.

- adding customer object to listbox Hi forwheeler, According to your code, you are adding the string object (Customer.FName) to your ListBox¡¯s item collection, so the SelectedItem will return the string object. You cannot convert a string object to a customer object. Thus you cannot get the CustomerID property. I am not sure how did you implement drag and drop between ListBoxes. But I have the following code, and I can drag and drop the customer between ListBoxes. Code Block public class ListBoxDragAndDrop : System.Windows.Forms. ListBox { private int lastMouseUpItemIndex = -1; private bool isDropSource = false ; public ListBoxDragAndDrop() { AllowDrop = true ; // allow D&D SelectionMode = SelectionMode .One; // single selection DragDrop += new DragEventHandler (OnDragDrop); DragEnter += new DragEventHandler (OnDragEnter); MouseDown += new MouseEventHandler (OnMouseDown); SelectedIndexChanged += new EventHandler (OnSelectedIndexChanged); } private void OnDragDrop( object sender, DragEventArgs e) { if (e.Effect == DragDropEffects .Copy) { System. Console .WriteLine(e.Data.GetFormats()); Point point = PointToClient( new Point (e.X, e.Y)); int index = IndexFromPoint(point); if (index > -1 && index < Items.Count) Items.Insert(index, e.Data.GetData( "ListBoxP.Customer" )); else Items.Add(e.Data.GetData( "ListBoxP.Customer" )); } } private void OnDragEnter( object sender, DragEventArgs e) { e.Effect = (e.Data.GetDataPresent( "ListBoxP.Customer" ) && !isDropSource) DragDropEffects .Copy : DragDropEffects .None; //ListBoxP is the namespace. } private void OnMouseDown( object sender, MouseEventArgs e) { if (MouseButtons == MouseButtons .Left && SelectedIndex == lastMouseUpItemIndex) { isDropSource = true ; DoDragDrop(SelectedItem, DragDropEffects .Copy); isDropSource = false ; lastMouseUpItemIndex = SelectedIndex; } } private void OnSelectedIndexChanged( object sender, EventArgs e) { lastMouseUpItemIndex = SelectedIndex; } } Hope this helps.

- Convert DBCS to Unicode and Viceversa Use Encoding.GetBytes() to convert the Unicode string to bytes. You'll need to obtain an Encoding instance with the System.Text.Encoding.GetEncoding(). Pass the code page number that matches the code page that the middle tier expects. You go the other way around with Encoding.GetString().

- WebBrowser Class Absurd I wouldn't be so quick to start throwing around that word. If you were to look at the documentation in MSDN for the webbrowser control you can clearly see that it in fact does use the settings specified in Internet Options. As far as I know the reason for this is that the WebBrowser control *is* Internet Explorer, the control just gives you a programmable API for it. In fact I'm sure this control is nothing but a wrapper for the old AXWebBrowser Control. An example from the goHome method: You can use this method to implement a Home button similar to the one in Internet Explorer. The user can specify a home page in the Internet Options dialog box, which is available from Control Panel or from the Tools menu in Internet Explorer. http://msdn2.microsoft.com/en-us/library/system.windows.forms.webbrowser.gohome.aspx Tag: Windows Forms Data Controls and Databinding display member of checkedlistbox Windows Forms

- call instance of main form Hi, I have another problem with the login form, I have my login form which is the main form of my project, when the user types in the password and the username in the login form, this data is passed to the other form (the one that loads the data) using the constructor, then this form builds the connection string for the oracle connection and tries to open the connection, however if the password is not correct and I get an error from the oracle client I need to show the login form again. Could somebody help me on how to make the login form again. by the way, the login form is never closed, I just hide on the login button login click event.

- Disappearence of Windows Forms Designer I just spent a half hour explaining why I can respond to remarks when I am not seeing my alerts, and why I had to go to experts exhange in order to get any reponse when I tried to post it and internet explorer 7 deleted my connection to the web site thereby losing everything. To restate. as I explained in another thread in these forums which has been view 68 times without a response, I am not receiving any email alerts. In addition, by following the options laid out in another thread by a person with the same issue, I am unable to change the options to reflect my preference to receive alerts at my current email address. Therefore I check the forums manually several time a day to see if there has been a response. After waiting two weeks to receive answers on other issues with this same application and seeing the request for assistance viewed I decided I was not going to wait on this issue so i immediately went out to experts exchange, where I received a response within 12 hours, and on which there has been considerable discussions. In answer to mr gazit questions, yes, yes, yes, and as I initially stated no error message, just a blank code page. Further information may be found at http://www.experts-exchange.com/Microsoft/Development/.NET/Visual_Studio_.NET_2005/Q_22829083.html Including the entire source code for frmReadXML.Designer.vb. This application is being built for the department of defense and there are lives at stake. I have been running the application as if it were a VB 3.0 application and making all my changes to my form in code which is tedious and aggravating. Now to cap it off Visual Studio 2005, after running in debug mode all night has decided that it can no longer find the source code for the reference class. Then it decided that it could not load the referenced class because it was supposedly "in use by another process". None of this used to happen in Visual Studio 2003, or VS 6.0. Why is it happening with a supposedly improved product (This time I am copying the comments out to notepad so I won't lose them when IE7 breaks my connection.

- adding objects to custom combobox Hi, having implemented this I just wanted to come back with the solution that eventually worked for me. I tried overriding the onhandlecreated method and this cured the problem of having the items loaded into the control twice - the desiner now does not include the code to load the items. However, an error occured when the application was running with the combo was dropped down and I tried to scroll down to the end of the list of items. The error was flagging that the selectedindex was not valid - i.e. greater than the amount of items in the control, from the scrollbar in dropdown portion it looked like it was scaled to be twice as many items (if that makes sense) but the item count was correct. I tried a few different things and eventually found that if I put the loading of the combobox items in the oncreatecontrol method then everything worked fine. I don't know why I was getting the error when the code was in the oncreatehandle method - if anyone has any info then please let me know, likewise if there are any issues with using oncreatecontrol.

Of cource the DataGridViewCheckBoxColumn can do the thing you want:
this.dataGridView1.Columns.Insert(0,new DataGridViewCheckBoxColumn());
This statement insert a DataGridViewCheckBoxColumn at the first column, it's just a checkbox column without any relation with your datasource if you do not set the DataPropertyName property of this column.

I think using a datagrid view is overkill if all you want to do is have a bound checkedlist box

Me.ChListGroups.DisplayMember = "GroupName"
