Hello,

I want to hide CDialog when application is started and show that in my other thread when some conditions meet.

I tried the following ways, but didn't work.

- Call ShowWindow(SW_HIDE) at the end of OnInitDialog
- Call m_pMainWnd->ShowWindow(SW_HIDE) in CMyApp::InitInstance() before calling dlg.doModal().

Thanks.
Paul.

There are a couple of approaches to this. I just saw Solution 1 which has a link I was just about to post along with the ones below.

Solution 3

You just should call the function in 'OnPaint'.Like this:

C++

if (bHide) //Initialize 'bHide' as TRUE in constructor
{
    ShowWindow(SW_HIDE);
}
else
{
    ShowWindow(SW_SHOW);
}

In your thread,you can do this:

C++

bHide = FALSE;
Invalidate();
