map<int ,UserControlInfo>* RSUserControlContainer::GetAnswers()
{
    //UserControlInfo is a structure
    map<int, AnswerType> mapAnswers = new map<int, AnswerType>;
    return mapAnswers ;
}

The compiler is probably complaining about returning an AnswerType map when the function's return type specifies a UserControlInfo map.

Hi,

I'm dynamically creating a tab control as a child of a dialog. When it is displayed initially the client edge is not visible (but the tabs are shifted according to the place the frame needs). When the dialog is covered and afterwards visible again, the client edge is displayed correct.
To force an update directly after creating an adusting the tab control I sent a nc update messsage like
MyCTabCtrl.PostMessage(WM_NC_PAINT);
But this did not help, either.

Any ideas?

I'm still using VC6, MFC4.2.

Regards
Leo

Try this:

MyCTabCtrl.SetWindowPos(NULL, 0, 0, 0, 0, SWP_NOZORDER|SWP_NOMOVE|SWP_NOSIZE|SWP_FRAMECHANGED);

I think this should work, assuming I understood your question properly.

Is the line where you call CDialog::OnOK() inside a member function of the CDialog?

Let's accallerate this, so that I do not need to wait for your reply.
Also I'm not sure, if my question was clear.

I suppose you are doing something like

DialogA::OnUpdateUI()
{
    CDialog::OnOK();
    pDialogB = new Dialog B;
...
}

Since OnOK() of the base clase does the same like hitting the OK button I guess that DialogA is destroyed. If this is true than at the next line you try to execute code in a non existent object.

Maybe

DialogA::OnUpdateUI()
{
    DialogA.ShowWindow(FALSE);
    pDialogB = new Dialog B;
...
    CDialog::OnOK();
}

works?

Regards
Leo

How to activate intellisense in C/C++

I`m a programmer of C# and I`m starting to develop in C++.
Why is it that sometimes my intellisense will not work or show.

Just like in C#, if you just type first letter, it will show unlike in C++. Nothing happen. Is this the behavior of C++ 2005 express edition?

Can you explain...

Thanks in advance.
