Child Dialog constraint inside a Window

[Aidoru]

Hello everyone,
could you please help me to find a good solution to constraint a dialog inside a window? So it move when window move, resize when window resize and so on.

Thank you

Are you using MFC, WIN32 API or some other framework?

I created a dialog in my .dll using createdialogparam and I call it from external program where I have parent window

No matter what part of process code creates it, a child window moves along with its parent. However, resizing is totally different aspect. Beng resized the parent may resize its child as well, or inform the child using custom message to let the child adapt. Or the child may monitor parent's resizing by installng a hook. The way you go really depends on many other factors, so it's fnally up to you.

Same to "and so on" part.

I think the problem is that, I created my dialog as follow:

CreateDialogParam(hModule, MAKEINTRESOURCE(IDD_DIALOG1), parent_Handle, DialogProc, 0);

but when I move parent window (parent_Handle is its hwnd) the dialog doesn't move, like it isn't a child.

I tried using SetParent to set dialog child of the window, now seems to work (moving parent move child too) but I have big paint problems on dialog, dialog disappear or paint only 1 or 2 controls and the dialog background look like parent window background.

Is there any solution?

Thank you

Solved changing GWL_STYLE of parent window (do you know better solution?).
But finally I don't understand a thing: why if I put window parent handle in CreateDialogParam function I still need SetParent function? Without SetParent can't solve my problem, and if I remove parent window handle from CreateDialogParam function nothing change!

Thank you

Whether the dialog is to be a child or not is controlled by dialog template styles. Afraid the dialog template IDD_DIALOG1 has no WS_CHILD style, but does have something like WS_POPUP, or thickframe, or overlappedwindow, etc.

You do have DS_CONTROL which should work.
