Passing Parameters between Dialog Boxes

[skyadel]

Say a user would open up DialogA (modal). From Dialog A, the user click on a button to open DialogB (modal). In DialogB, the user will key in a value (double) into an edit box. How do I pass this value to another edit box on DialogA (which I would like it to appear to show an updated display) after the user close DialogB?
I encountered problem because there is no longer any INIT because DialogA is already opened... Is there any way to do things like UpdataData(); ???

By the way, I have already declared a global variable. Say double GlobalVar.
In a header file... I have extern double GlobalVar.
Then I include this header into the related source files of both Dialog A & B.

I'm a beginner and examples would be greatly appreciated. Thanks!

For beginners, the most important activity would be to obtain a beginners book. If that is not possible, you can learn to use the many freely available samples and articles from Microsoft. They can be found on MSDN online at

Hope this helps

Have you tried using a pointer? Create the pointer in
DialogA, You'll have to overload your DialogB constructor, Then, create the object for dialogb, pass the pointer to your dialogb constructor, in your constructor initialize your global pointer for that dialog to the pointer you passed in.
