Inserting MFC dialogs into MFC dialogs..?

[HairyDave]

Right, I have an MFC class derived from the CDialog class. I then have loads more of them. Is there a way to insert these other dialogs into the main dialog class?

If you don't know what I mean, I'm trying to create a GUI that has several stages. I want to place the dialog referring to the current stage into the main dialog so that it can be used.

For example, take a Wizard type GUI, when you press Next (or whatever) you are taken to the next page. Now, if that next page is a different dialog placed on top of the main dialog, then this would be approximately the same as what I want.

Hope you understand and can help.

Thanks

Did you try the SetParent() api? It requires the HWND for the proposed parent, proposed child.


It therefore also changes the message chain - so you need to watch out if you are trapping messages for your main window that you don't mess up messages meant for the child.

You mean a chain of dialogs like the VC++6 wizards?

[HairyDave]

Because I don't have many stages to my app, and I know the contents of the dialogs (controls etc), I will probably create dialogs for each stage. I can then load them when required.

I was asking if I could have a main dialog that would display these dialogs within it. Therefore pressing the Next could increment the counter and load a different dialog into the window.

I'm pretty sure that what you want is property pages.

[CornedBee]

No, not quite property pages. Those are a little different.

What is a controlling dialog good for? Why not have more than one dialog that all are top-level and simply shown one after the other?

[HairyDave]

As I said in my last post - thats probably what I'll do.

The reason for the control is that I have no idea how many Dialogs I may have. At this moment I do, but the expansion to the app could mean numerous dialogs.

Make an array of CDialog pointers (best would be a CTypedPtrArray or CTypedPtrList) and an index that indicates which dialog is current. When the user clicks next you increment the index, when the user clicks previous you decrement it. Do this in a loop until Finish is clicked.

Then all your dialogs are automatically shown and you only need to play around with creating new instances of various dialog subclasses that you then add to the array.
