Would like to move button in a function

Hello, I would like to send the button ID to a function (where I move the button).
The moving code works just fine, but I do not know how to submit the value/ID to the function.
It will not work as an int or as an CString.
Please help. 500 points with a solution.

Best regards,
Thomas

Button_ID=378;

             CRect CBtnRect;
             CButton *pButton =(CButton*) GetDlgItem(Button_ID);

             pButton->GetWindowRect(CBtnRect);

             //ermittle Koordinaten bzw. Maße umwandeln
              ScreenToClient(&CBtnRect);
              int nButtonBreite =CBtnRect.Width();
              int nButtonHoehe =CBtnRect.Height();
              int nButtonPosLinks =CBtnRect.left;
              int nButtonPosOben =CBtnRect.top;

              //Exitbutton verschieben
              pButton->MoveWindow(nButtonPosLinks+25,nButtonPosOben+25,nButtonBreite,nButtonHoehe,TRUE);

It will not work as an int or as an CString.

can you describe what you mean by 'it will not work'?

did you get a compiler error?
check the prototype of your new function in the header file.

did you get a crash?
check the pButton whether it is not NULL before calling GetWindowRect.
if it is null, check the Dialog resource whether the button was included and has the correct ID.

did you call CDialog::OnInitDialog() before moving the button?

Thank you for your help. I am sorry it was just my error.
I did this earlier and it would not work, I got a crash.
Verschiebe_Button_bei_groesser_Aufloesung(IDB_BITMAP_SPEICHERN_BUTTON_ANGEBOT);

Now I know what I did wrong. That was stupid from me.
IDB_BITMAP_SPEICHERN_BUTTON_ANGEBOT this is not a button, it is a bitmap. I have so many button and bitmaps that I choose the wrong ID.

With a real button it works just fine.
