I use VS 2005 on Vista ultimate 64 bit without issues. Did you install the service pack for VS 2005 and then the Vista compatability fix?

thanks for your answer,

I have download sp1 for VS 2005 and install this , But my problem exist !!!!

There are TWO things you need. SP1 *and* the Vista fix. Download the Vista fix and run it. If that fails...

Then maybe your tampering with it may have hosed it. Completely uninstall dev studio 2005. Everything. Reboot.

Reinstall Devstudio 2005.

Now the next part I can't remember off the top of my head. One part requires you to run dev studio first and the other must be done before it is run. You need to look online (probably the vista compatibility fix documentation).

I *think* the order is, Install VS2005, install SP1. Run Dev Studio, exit, then run the Vista fix pack. Or maybe it is install VS2005, the vista fix, then run it, then SP1. You really need to find some online documentation about it to be sure.

ok , I try install Vista fix and then put result here ,

but why my Activex wrok correctly in VB6 or Delphi without install Vista Fix?

I have no idea, but as a wild guess: Maybe your app is 64 bit and the OCX is 32bit?

I thought you were having problem running VS2005, not compiling a program in it. If VS2005 runs fine and it is a run/compile error with your app, make sure that it is set to make a 32bit app, not a 64 bit app.

ok , I set my Project in 32bit option and tell you result
