Only thing that comes onto my mind is that the function GetName() returns just a reference on a CString object.
But I doubt it's the problem...

I tried that. If I store the return value in a CString object the object has the data. If i am not concatenating, the window does not show it. I used another solution, i created another static field. I think it might have been that the pixel width given to the control was not large enough to show the full string.
Anyaways - thank you for your time.

Is there anyway to make a class a friend of it and anything that inherits from it? Thanks.

Classes are by definition friends to themselves ( anyone who is not their own friend has serious issues ), and anything derived from it ( most of us try to be friends with our offspring ).

Hey Everybody,
I made a dialog that has 2 sets of a radio button and combo box. When one radio button is set, it disables the other combo box (and enables it's own combo box) and vice versa. I can't seem to find an example where that can be done in the articles. I also want to return the results of the dialog to the calling function. I know it has to do with the DoDataExchange function. I've read though examples but they just say "do this and do that" but they don't tell me how to get it working with my own program. If I can get a set of steps to get it working, I can try and figure it out, I just need some breadcrumbs.
Any help would be greatly appreciated because the data exchanging thing is a very important part of MFC, thanks in advance.

One method is to create the radio button variables as controls not ints, and create event handlers that enable and disable controls when the respective button has been clicked. Then the OnOK can be overridden. This part is dangerous. I would recommend instead, creating a public variable that stores the radio button state, and then after the DoModal() function returns IDOK pull the value from the variable. Let me know if you would like more detail.

I understand that but I would like more on your recommendation. From what I read, you are supposed to create an integer public variable for only the first radio button and that will indicate which other radio button is selected. Beyond that, it's each variable for itself, at least the controls I'm using.

Hey all,
I've got a dialog program with a menu. I want to add a bitmap on the actual menu bar, not in a drop down. I want it next to the items... Example:
(BITMAP) File Edit View Help
Is there anyway to do this, and if so, how? I've tried everything, but nothing is working. Thanks a lot.
Dave

Mickael Dunn'advice is good.but I think there must be a method to do it by using member's function of menu class in MFC.you can refer to Microsoft Internet Explorer, bitmap lies of left of the items in "favourite"

I need to present the user with a disclaimer . The text is long and i want it to be hardcoded .
char *disclaimer = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa......" ;
Is there a limitation on the size of this string ?
for ease of reading I need to be assigning this as
char *disclaimer = "aaaaaaaaaaaaaaaaaaaaaaaa // line 1 (what delimiter to use ? )
aaaaaaaaaaaaaaaaaaaaaaaa // line 2
aaaaaaaaaaaaaaaaaaaaaaaa" ; // last linem
How can i achieve the above . in other words what is the delimiter to use ? is it \\

Use CString.format.
example
CString myText;
myText.Format("This is line one \n This is line two \n This is the last line.");
AfxMessageBox(myText);

Here is another way to do it (ANSI C):
char *disclaimer = "aaaaaaaaaaaaaaaaaaaaaaaa"
"aaaaaaaaaaaaaaaaaaaaaaaa"
"aaaaaaaaaaaaaaaaaaaaaaaa" ;

No. I've seen message boxes that consumed my entire 1024/768 screen.

The delimeter for the text in the messagebox is \n.

I'm wanting to add a OnTimer event to me UI thread class, but cannot seem to get it to work. I assume that the time only works with some kinda dialog, but my thread does not have that, only my main app does. Is there a way to add this event to my thread with out adding a dialog?
Thanks

So what does not work? When you create a timer via SetTimer(), it communicates back to the application in one of two ways: the function pointer that was provided, or by posting a WM_TIMER message.

It's never getting to my OnTimer function.
When you say function pointer ...what do you mean?
Thanks

A callback function.
void CALLBACK TimerProc(...)
{
}
SetTimer(..., TimerProc);

Let me ask you this. According to the MSDN is says that the hWnd is
Handle to the window to be associated with the timer. This window must be owned by the calling thread. If this parameter is NULL, no window is associated with the timer and the nIDEvent parameter is ignored.
My thread does not have a window associates to it. And I need for SetTimer to look at the nIDEvent parameter because I have three timers doing three different things.
Can I just pass the handle from my main app and still have the timer work in my UI thread?
Thanks

I havent done DX programming before but I found out that you can enter fullscreen mode by SetCooperativeLevel and pass DDSCL_FULLSCREEN as one of the params.
For OpenGL I ran accorss the following line of code: ChangeDisplaySettings(&dmScreenSettings, CDS_FULLSCREEN);
How do I determine if an app is running in the fullscreen mode?
