Stuck in ShowWindow

[dj4400]

Hi all, I have a multithreaded application written in c++ vs6. I try to create a new dialog within an existing dialog in that application and when i call ShowWindow(SW_SHOW)for the new dialog it doesnt do anything. If i put a break point there, it seems that it stops in the call to ShowWindow and doesnt continue the execution. Can someone explain this strange behavior and suggest a way to overcome this problem? Thanks Simon.

All these dialogs are created on the same thread?

Doesn't that tell you exactly what is being done? It's created within  :laugh:

yes all these dialogs are created in the same thread. To be more precise i call the create function for that dialog in the ctor of the containing dialog and i call the ShowWindow(SW_SHOW) from within the OnInitDialog ,just before i return true for the OnInitDialog. :sigh: dj4400 formerly known as ddd_shocron

If the containing dialog is used as the parent for the created dialog, then that may not work - the parent dialog window (HWND) hasn't been created yet at that point. Try calling create for the child dialog in the parent's OnInitDialog() (after calling the base class' OnInitDialog()). Mark

Thanks Mark, you are right - i called the create function in the OnInitDialog and then it worked properly. :)
