• SQL Server System.Transactions issues

  Hi Is it necessary to have the connection open code inside the transaction scope to be able to use transaction features. I wrote a code which has the connection.open outside the transaction scope and it wasn’t working correctly. When i moved the connection.open inside the transaction scope it started working fine. Apart from this is there any special setting i need to do (DTC related) while working with System.Transaction and SQL Server 2000.

Thanks Hi Ams, It is necessary to open the connection inside the Transaction ...Show All

• Visual Basic Combobox rebinds unexpectedly

  I'm writing a VB.NET (1.1) application which enables me to select a group of students (klas) in a combobox. Then all students in that group are shown in a second combobox.

(via the SelectedIndexChanged event) But when the fill method of the dataAdapter is executed the SelectedIndexChanged event is fired again.

• Visual Basic Setting form time out to exit if idle for xx minutes?

  Hi, Does someone have a code snippet or reference page that illustrates the use of a form timer or variable to be set that allows one to set a limit on an open form to close after a period of time if no activity has been done.  I want to close/exit a form if the user has not entered or clicked a field for, lets say 15 minutes.  If there has not been any activity then close the form and return back to the main form.   Thank you from a newbie.

• Visual Basic Combo boxes in datagrid view give errors when closing form (VB 2005/.net2/sql 2005)

  Hi, Althiough an experienced programmer (20+ years) this is the first time in 10 years that I've had to use VB so apologies if obvious answer. I'm using a combo box inside a datagridview. The combo works correctly pulling data from lookup table and placing it in the grid table. I can save the data okay. I can exit the application fine, but if I try and close the form either programatically or using the close button on the form I get an error that the values in the combo box are invalid. This occurs after the FormClosing event is fired. Anyone else seeing this or know of a workaround. It didn't occur in the VS 2005 CTP but does in the ...Show All

• Visual C# how do i prevent "show desktop" or "windows key+m" from minimizing my program?

  hi, i don't want my program to be on "TopMost" but i also don't want it to minimize. Never. even if i disable the minimize feature, the program can still be minimized by clicking on the "show desktop" icon or pressing Windows Key+M. I'd like to prevent that. Can someone tell me a possible way to do it btw, the "show desktop" button doesn't trigger the 'resize' or 'changesize' event in the form. Thanks, For the heck of it...I tried to to do this with Desawares subclassing ocx. (the best I know of) You can stop the minimize event with this....but WinKey m...will always minimize it.

• .NET Development DataBound Tag Property

  I have a form that has a TextBox that has the Tag property bound to a DataSet.  Even if no changes are made to the form, the DataSet HasChanges() method returns True.  If I switch the binding over to the Text property, it returns False, like it should.

• Visual Studio Problem: DirectX help not setup for use in visual c# 2005 express

  Hi, sorry if this has been asked before, but I didn't find anything on these forums, so here is my problem: Well, I recently installed visual c# express edition 2005, which seems to work fine.
