Pass info class to class

Class CSDITest1Doc creates a new instance of a dialog class. Works OK. Example below:
CTestDlg* aDlg = new CTestDlg();//code is in CSDITest1Doc From class CSDITest1Doc I can execute functions of the new CTestDlg. For example, LoadMessage() is a function of CTestDlg. Works OK. Example below:aDlg->LoadMessage();//this code is in CSDITest1Doc Sometimes I want to alert CSDITest1Doc of something that happens in CTestDlg. Sometimes I want CTestDlg to ask for data from CSDITest1Doc. Suppose XYZ() is a function of CSDITest1Doc. How do I execute a XYZ()of CSDITest1Doc from CTestDlg? -

One way is to pass a
CSDITest1Docpointer to theCTestDlginstance.

I tried this, but found I didn't really know what to load into the pointer. In
CSDITest1DocI entered the following code. I figured if I could get the pointeraDocloaded with the address of the instance ofCSDITest1Doc, I could call a function fromCTestDlg, and use that to pass the pointer to CTestDlg.CSDITest1Doc* aDoc; aDoc = ???????Is this a correct approach? Thanks -

No. Try:
CTestDlg* aDlg = new CTestDlg(this); //code is in CSDITest1Doc
Remember to create an appropriate
CTestDlgconstructor.
