Hi,

I have a VB application that runs full screen. On the click of a button on the VB application, an applet is opened. On the click of a button on the applet, it calls a c++ dll (twain) and this dll has the code to create a pop up window and this window goes underneath the full screen VB application instead of being at the top.

Can someone let me know the way i can get this pop up window onto the top of full screen VB form and the applet?

Thanks in Advance,
Kris

You're probably getting downvoted because you posted a VB question in the C++ forum. Choose the Visual Basic forum next time. :)

Hans, he tagged it as C++ but it's just a tag. Many people get the tags mixed up :-)

I posted this question here because the applet internally calls a twain dll that is in c++ and this dll creates the window. So please revoke the downvote.

Solution 2

You can implement following into vc++ dll

C++

CWnd *pCalc = CWnd::FindWindow(NULL, _T("Applet Name"));
if(pCalc != NULL)
{
   pCalc->BringWindowToTop();
   pCalc->CenterWindow();
}

You can also use MoveWindow(); To move window at desried location with size.

Solution 1

Just make the window settings to OnTop while creating that window.

If possible you should pass your window handle to the called procedure as parent window. Otherwise you can install a hook to do that (SetWindowsHookEx(WH_SHELL,...)). Catch the HSHELL_WINDOWCREATED message and set yout window as parent (SetParentWindow, or SetWindowPos or SetForegroundWindow etc. pp.).
Regards.
