Using the basic code below, I am tring to change the caption(title bar) of the Dialog at run time. It does not work for me........my environment is net 7.1,MFC.
Any ideas on how to solve my problem?
void SystemAlign::OnBnClickedOk()
{
CPropertySheet mySheet;
mySheet.SetTitle(_T("Junk One"), 0);
mySheet.DoModal();
}

Is SetText() a method of CPropertySheet?

SetText is not available in my environment which is net 7.1, MFC
|
|
|
|
|
SetWindowText() is a class member of CWnd and so will work for any window, including dialogs & propertysheets.

Do you mean it wont compile or nothing happens when the code executes?
Can you show your code fragment.
SetWindowText() is the correct method to use, there must be something else wrong.

It gives me an Unhandled exception....see code below and remember that my environment is net 7.1, MFC.
void SystemAlign::OnBnClickedOk()
{
GetDlgItem(IDD_SYSTEM_ALIGN)->SetWindowText("Junk One");
//CPropertySheet mySheet;
//mySheet.SetTitle("System: Signal-To-Noise", 0);
//mySheet.DoModal();
}

Going this route, you'd need to call SetWindowText() in the sheet's OnInitDialog() method.

I get the same Unhandle exception by placing it in OnInitDialog(). I think it is a different method call in net 7.1......I am wasting so much time digging for such a simple problem.....

But how are you calling the SetWindowText() in there?

I'm calling it like this
GetDlgItem(IDD_SYSTEM_ALIGN)->SetWindowText("Junk One");
|
|
|
|
|
Which is incorrect. Remove the call to GetDlgItem().

David,
It works on both ends, referencing the GetDlgItem was my problem.
Thanks a lot....

Both ends of what?

This works fine in v6. It must be something specific to v7.x, or you have other code in place that is masking the problem.

SetWindowText(...) will work i suppose.

Can someone please verify that if a derived class redefines a protected virtual function from the base class it must be redfined as a public member in the derived class. So for instance,
class Core {
protected:
virtual double grade(double) const;
};
class Grad: public Core {
public:
double grade(double) const; // OK, it's public.
protected:
double grade(double) const; // NOT OK!
};
If true, can you please provide the logic behind this? Otherwise, why is VC++ 6.0 complaining?
THANKS!! Much obliged!

It's not true. Otherwise, what would be the point of a protected virtual function if you had to make it public?
If you remove the public version from Core it should compile.
|

There is no public version in Core, only a protected version. The example shows a redefined function in Grad: one version is public and one protected. They are mutually exclusive. I only put them both there for the example.

This compiles
class Core {
protected:
virtual double grade(double) const;
};
class Grad: public Core {
protected:
double grade(double) const;
};
Nevertheless its better to keep in the declaration
virtual double grade(double) const;
cos maybe ull have another level of derivation

Thanks! I found the problem (but don't quite understand it). It's related to a clone function that I had in my derived class. When I remove the private clone function I get a clean compile. From Accelerated C++:
The return type for the clone function in class Grad must be changed to be a Core* rather than a Grad* as written in the book:
#ifdef _MSC_VER
Core* clone() const { return new Grad(*this); }
#else
Grad* clone() const { return new Grad(*this); }
#endif
because VC++ 6.0 does not yet allow a virtual function returning a pointer (or reference) to a base class to be defined in a derived class to return a pointer (or reference) to the derived type.
