• Visual Studio Tools for Office how to add xml markup to a range

  Could somebody give me some reference links with samples on how to add xml tags to ranges. I need to add those at runtime, have them not show up to the user, and be saved with a document.

• SQL Server navigation on subtotal

  I have a matrix and a subtotal footer summing up a group of numbers. Each row has a primary key. I use the primary key to drill-through another report through "Navigation".

• Visual Studio Team System Is it possible to change the connection string property of a Web test datasource?

  Hi all, thanks in advance for your help. We are developing a series of web tests to be used for performance testing. These tests use a local database for parameter data. What I have not been able to change is the connection string of the web test datasource. If we move the tests to another testers machine, they have to create a new datasource, re-establish all of the bindings in the Form Post parameters and then delete the original data source. Is there something I am missing here It may just be a case of 'functions as designed' due to security concerns. Thanks, Shawn Thanks, ...Show All

• Windows Forms DataGridView + RowValidating = Index 4 does not have a value?

  Hello, I recently setup my DataGridView to use the RowValidating event.  However, whenever a user types something in to a NewRow (as to cause the DGV to create a new row and consider the current row's NewRow = false) and then hit escape to cancel the edit, the DataError exception goes nuts.  It keeps spitting out "Index 4 does not exist" in what seems to be an infinite loop. Here is my RowValidating code: private void dgvMain_RowValidating( object sender, DataGridViewCellCancelEventArgs e) {   if (dgvMain.Rows[e.RowIndex] != null && !dgvMain.Rows[e.RowIndex].IsNewRow)  {    string er ...Show All

• Visual C# Custom control draws incorrectly when moving another window over it.

  This issue has seriously frustrated me. I am overridding OnPaintBackground to draw a gradient background in my custom control. It resizes great - very smooth, no flicker. When I try to move another window across it, it will repaint itself repeatedly... but it will repaint the area that was hidden by the window as if it was the entire control. So if I am starting the gradient from blue to green...When I move a window over half of the control, and then start moving it off, it will start painting the blue in the middle of the control. So after I have the window off the control...the first half of the control looks normal. The second half looks ...Show All

• SQL Server Native XML vs relation data

  Hi, Our application constructs XML reports by getting the XML file information from an SQL 2000 or 2005 database. we would like to find out if there would be better performance or not if we would no longer store the XML Reports definitions inside SQL database and rather keep them as files on the IIS server If for example 10-50-500 users are accessing reports in the application would overall performance be better if IIS would physically use the XML reports stored on its hard drive or continue constructing XML reports on the fly by retrieving the report's info from an SQL table Or may be you would suggest a different approach alt ...Show All

I wrote an app, built it as an .exe and went to put it on a server, for example P:\MyProgram\the.exe I want to drag a shortcut to P:\MyProgram\the.exe onto a local desktop (4 different ones in our office actually) so that way, any time I make a code change to the.exe, I can just upload to P: to overwrite the existing .exe but the shortcuts will still work on the local desktops.
