>This mean that ShowWindow property value of your form is 1 (In screen). Change it to 2 (As Top Level form) and should work.

Yes, this should work, I've seen the VSP help and the sample "...\Samples\Solution\Forms\Sdiform.scx" which is describing an SDI (Single Document interface) form but when I tried to compile it into an exe file and ran it, the exe file just flash. I thought maybe because of the windowtype=modeless so I changed it to modal, but it made no diferrent.
Any idea ?
