Change caption on checkbox button at Runtime in VC++ 7.0

I am looking for a way to modify the caption of a checkbox in a MFC dialog at runtime.

// With associated member variable to the checkbox
m_Checkbox.SetWindowText("Caption");

does not work. GetWindowText shows an empty string and

SetWindowText does nothing.

The mfc help says "If the window is a control, the text within the contol is set" (not the caption)

How to set the caption? Am I doing something wrong in SetWindowsText or is it not the correct way?

Thank you for your help

Check to see that if control variable points to control properly or not.
Try using GetLastError and determine cause in Error Lookup utility.

Thank you for your suggestion.
Since it was a simple dialog, I restarted from scratch and it worked, some file must have been corrupt.

>Check to see that if control variable points to control properly or not.

I was wondering how to do this. How do you determine the connection between the appname.rc, the apnname.h and the Resource.h file. In the apnname.h file I only see the declaration of the variables, but not to which control they are linked.

in your DoDataExchange(CDataExchange* pDX)

there will be lines like this that determine the linking and subclassing behind the scenes.

DDX_Control(pDX, IDC_BUTTON1, m_Btn);

Thank you all for the help
