Hy Phil,
one of the persons who asked this question to Mr. Wampler recently was me. So, to
make the answer more precisely: you have to include in the class you derive from
vDialog (e.g. MyDialog) a pointer to MyCmdWindow (derived from vCmdWindow) and
initialize this pointer in the constructor of MyDialog. The constructor head line
would then look like this:
"MyDialog (vBaseWindow* BaseWindow, char* Title, MyCmdWindow* _pParent);"
Inside the constructor there must be a line like
"pParent = _pParent;"
where pParent is the new pointer mentioned above. Surely, in the constructor of
MyCmdWindow, you now write like
"SomeDialog = new MyDialog (this, "a title", this);"
And if you want to send a message from your dialog to the command window, you do it
like
"pParent->DrawText (.....);"
This is quite simple and worked fine for me. Hope that it works also fine for you.
Greetings
Matthias
