• Windows Forms DataGridViewComboBox System.Argument Exception

  Hi All, When I create DataGridViewComboBox columns and add them to a DataGridView I keep getting a System.Argument exception if the items contained in the ComboBox are not already within the DataSource. Has anyone else experienced this problem If so how did you handle the error Moreover, is it possible to suppress the error and continue with the programs execution normally Cheers, sfx If you do need to suppress the error, handle the DataError event of a DataGridView class. You may even leave the event handler empty, just create it. ...Show All

• .NET Development "Plus equals" pattern in IL gives incorrect results

  When people claim to have found a bug in the CLR, I am normally the first person to tell them to go back and find the bug in their own code, since that is far more likely than the problem being in the CLR itself, given how stable the runtime has been since its release. However, I believe I have isolated a case where the runtime, or something operating at or below the IL level, is behaving incorrectly. (Note: the problem I describe here only occurs in version 1.1 of the CLR; version 2.0 does not appear to be affected) This case evolved from a bug I was having in a VB.NET app, but after disassembling the app and playing with the IL code, I am confident that the problem has something to do with the IL itself. Basically I am performing a "p ...Show All

• Visual Studio Express Editions concerning media player

  renee where do I post pause button code Here's the point. It's a burden and I recognize that. I'm here to help you. So in my eyes, the question becomes, to what extent are you willing to help someone who is helping you Who is to assume the burden. It's not easy to debug a noobie's code. It's much worse when I have to do the mental gymnastics to format your code in my head. That really distracts me from helping you. I'm really willing to work hard for people but I do have expectations. My expectation is that they do their share of the work and not have me do all of it. If they want to put unreadable code up, fine. In that case, I feel they haven't done everything they can to make things easy for the volunteer who i ...Show All

• Visual FoxPro Copy classes or subclass from a classlib

  I am obviously still learning and making changes in my original classes in my first application. I have a second application which I am developing now. The second application will need to use classes similar to the first application, but some classes will require  minor and others major changes. I'm not sure if I should copy the classlib and modify it for the second application, or sub-class from the first class lib. Also, is there an easy way to copy individual classes from one classlib to another Please keep in mind that the first classlib will be modified heavily in the future. Any ideas for a strategy would be greatly apreciated. If these are un-connected app ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Minimizing and Maximizing

  I have my application set to use the full screen. If I hit alt tab, go into another app, then alt+tab back into my game, it's solid gray, and then locks up. I wrote some simple code to check the keyboard state, and close the app if I hit escape, but that doesn't even work. I just assumed that this would all be handled for me, out of the box... Do I have to write anything myself to fix this I am still using the beta version, and the method that was generated for me didn't have a parameter. Aparently, the generated code changed between the beta version, and the 1.0 version. When I try opening the sln in the new version, I get an error telling me that the project was saved in an incompatible version of XNA ...Show All

• Visual Studio Tools for Office Custom Task Panes in Outlook 2003

  I had been scratching my head for past few days but did not came to find any clue. I am interested in getting custom task panes to work exactly the way it works in Office 2007. Although the object model is quite dis-simmilar, yet is there any alternate way to display custom task pane or to display a user-defined windows control in an existing task pane in 2003 Any help would be appreciable. Thanks Hi Imran If I understand correctly, you're asking whether one can use VSTO to modify a built-in task pane in Word 2003 No, there is no interface to change the contents of Word 2003's built-in task panes. You can use VSTO 2.0 to create a custom taskpane for Word 2003, and that can contain a Windows form ...Show All

• Windows Forms Combo Box Items Value

  Hi Guys, I wanna have a combo box that returns a value other then its text to its data source. Basically, I have a textbox that has the values 'Male' and 'Female' and I have it bound to a datasource and I want it to return a value of just m or f. Any ideas Thanks in Advance Hi, if you're databinding your combo, you can use its DisplayMember and ValueMember properties. DisplayMember is the datasource item's field, which will be used displaying in the combobox's text area, and ValueMember will contain the item's value. For example, take a look at this code: DataTable table = new DataTable (); table.Columns.Add( "GenderDescription" , typeof ( string )); table.Columns.Add( &quo ...Show All
