• Visual Studio Express Editions Creating reports from VB

  I'm completely new to Vb2005 and would like to know what reporting tool is best to use with VB and how to integrate the two to create reports that are printable and can be sent to either a word or pdf document Hi, There are currently 2 report creation tools available in VS2005.

• SQL Server Mix Relative and strict dates

  I am trying to write a report where I can have a drop down with values like yesterday,today,lastweek. But I also want the user to be able to select a specific range, say 7/1/2006 to 7/5/2006. Also why can't i update the value of a parameter through to an expression Like set the value to =Today(). It throws an error about the type. Can someone point me in the right direction here I think the issue is that you are passing the string '=Today()' where a DateTime is expected. Expressions are not evaluated here, so you need to specifiy the actual value, instead of an expression. E.g., DateTime.Today. Or you can place the "=Today()" expression directly in the Report for the parameter, where it will be evaluated. ...Show All

• Visual Studio Team System Schema Compare Problem #2

  I have noticed that when I compare a Database to a Project, and as a result of the compare, objects need to be deleted out of the Project, the objects are never deleted. I can run the compare process over and over again, the same objects show up to be deleted, I will click on Write Updates button to update my project (which should delete the objects), but the objects are never removed. Is this a known issue Or am I doing something wrong Amos. Alle, In your reply you referenced a real world case where we might compare the "deployed DB to the project". This is not the way we are working. We each have our own local development database that we synch back to the project. Therefore, we could ha ...Show All

• Visual Studio Team System Problem with Open Selection in Microsoft Excel tool

  A couple of weeks ago, I was able to succesfully use the "Open Selection in Microsoft Excel" tool in Team System to export work items to Excel for mass editing. This was working in Excel 2003. Since then, I installed Excel 2007, and now this tool no longer works. When I try to use it, Excel 2003 opens, and then I get the error message: TF84040: There was a problem creating the document. I have seen a similar error on other machines, and actually had this happen when I first installed Team System. When this first happened, I uninstalled Visual Studio and Office, and then re-installed Office and Visual Studio (in that order). This fixed the problem, but was very time consuming. There has to be an easier way to fix this. Anyon ...Show All

• Internet Explorer Development Hotfix completed

  Our product is suffering some pretty severe problems because of IE7. We've starting getting calls that dialog windows become hidden. We've heard this is a threading issue. We found out that the problem is actually much worse. Modal dialogs don't seem to function correctly in IE7. You can recreate the problem using VB6 by doing this: 1. Create an ActiveX UserControl project. 2. Add a form to the project (form1) 2. Put a button on the user control (usercontrol1). 3. Add this code to usercontrol1. Private Sub Command1_Click() Dim objForm As Form1 Set objForm = New Form1 Call objForm.Show(vbModal) End Sub 4. Build the project as an OCX somewhere on your hard drive. 5.
