Dialogs & WS_VISIBLE

Please help.

I already had in mind the "switch" trick , but I could not think that WM_WINDOWPOSCHANGING should be trapped . Why the hell Windows does not take the style from the resource ?
Thanks nietod .
Thanks nietod .
It does use the style in the resource. It creates the dialog as an invisible window, just like you requested. However, later on (sometime after WM_INITDIALOG) it displays the dialog.
I'm not sure when you want it visible and when not, but it sounds like you want to create it invisible, right? In that case, I would "hook" the WM_WINDOWPOSCHANGING message. In there get a hold of the WINDOWPOS structure and then set the SWP_HIDEWINDOW bit flag of the flags member. That will make the window invisible
Of course you will need some sort of "switch" to determine when your code should set this bit flag and when it should not. Otherwise, the window will never be visible.
