Re: Access Canvas from Modeless Dialog?
Mathias has the solution I would use, though I would modify it slightly to make it more const-correct:
class MyDialog : public vDialog
const vBaseWindow* baseWindow,
const char* title,
const MyCmdWindow* pParent)
: cmdWin (pParent),
vDialog (baseWindow, 0, title)
// constructor code here
const MyCmdWindow* cmdWin;
cheers... Tom Hilinski

| 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
| "pParent->DrawText (.....);"
