• Windows Forms Why is ClipRectangle always 1px too wide and high?

  As already in the subject. If you have a Graphics objects of a control and check the ClipRectangle property it matches the size of the control, however if you try to draw a border:             Brush b = new SolidBrush(SystemColors.ControlDark);             Pen p = new Pen(b, 1);             e.Graphics.DrawRectangle(p, e.ClipRectangle);   the bottom and right lines can't be seen because they're 1px too wide.

• Visual C++ floating point performance on x64 (AMD Opteron)

  I am porting a numerically intensive application from VS7 to VS8.  Surprisingly the Win32 Release exe (VS8) is 3 times as fast as the x64 Release exe in a matrix solver soving an array of double.  I am using the same optimizations (/O2) for both x64 and Win32.  Does this seem right   I had been hoping for a speed improvement with the 64 bit version.

• Windows Forms ClickOnce Installs fail, ADODB 7.0.3300 required?!

  While trying to use the new ClickOnce in 2.0 (RTM), the installs fails on the majority of machines.  I receive the error that says.  "Unable to install or run the application.   The application requies the assembly ADODB 7.0.3300 to be installed in the Global Assembly Cache (GAC) first." The only 2 depenencies that this app requires is the .NET Framework 2.0 and the report viewer pack.  I believe it the report viewer pack is causing the problem.  Any ideas or suggestions on this problem   If I can't use apps that use the new reporting controls then clickonce is basically worthless for the majority of ...Show All

• Visual Basic Connection String To Northwind

  Since I have been trying for some time to populate a treeview with a database, I am excited to see this thread.
