• Software Development for Windows Vista ActivityValidator questions

• Windows Forms Controlling font width and height independently

  I write on a form using ‘Drawstring’. I want the text to fill out the form, so when the user resizes the form, the text is resized. So if the form is long and narrow, the font width will be wide and the font height will be narrow. How can this be achieved Thanks, The ScaleTransform method can do what I want so it was more simple than I had hoped for. ...Show All

• SQL Server Take Id-s From returned rows, and make a new SELECT

  Hello, I have a question on sql stored procedures. I have such a procedure, which returnes me rows with ID-s. Then in my asp.net page I make from that Id-s a string like SELECT * FROM [eai.Documents] WHERE CategoryId=11 OR CategoryId=16 OR CategoryId=18.

Then change the WHERE clause to something like this (i left out the conditions): WHERE CategoryId In (Se ...Show All

• Visual Studio Team System Visual Studio 2005 Team Suite Release on MSDN Subscriber Downloads (Universal)

  Hello everybody, Today Visual Studio 2005 Professional was released on MSDN Subscriber Downloads. We were unable to find the Team Suite Release. Any help Best regards Ralf Rottmann If you are an MSDN Universal subscriber, you should see a Visual Studio Team Edition download. That's the one you need. You also need to install the Team Foundation Client Beta 3 that has been out for a while. However, I would lay off doing that for a while until we know the status of the "Team Foundation Beta 3 Refresh" that was supposed to be coming out at the same time as VS2005 RTM.
