I want to UpdateData(false) but only for one of the CEdit Boxes in my Dialog;
I tried:
                CString m_Bild=AnyString; //Value of that CEdit Box
      CEdit m_BildCtrl.UpdateData(false); //Control of that CEdit Box

but it dont updates the data.

The parameter to UpdateData() is called bSaveAndValidate. This means that if this parameter is set to true, you are retrieving data from the control (and validating it). If you set it to false, you are setting the the control (copying from your variable to the control).

Which way do you want your data to go?

The line that you quoted will not work. You need to do it like this:
m_BildCtrl.UpdateData(false);

I usually get this wrong myself :-) That's why I try to remember the "validate" part of the parameter name. Validation only makes sense when reading from the control, so "true" therefore must be control->variable

UpdateData takes a BOOL not a bool, so strictly speaking you should pass TRUE or FALSE, rather than true or false.

Call me pedantic....!

martynjpearson, you are pedantic :-) But you are of course right. I do however only use true and false in my code, and (besides the occasional warning) it does not make a difference. I am used to a "real" C++ environment :-)
