    Problem with SetDlgItemText

    ok...to make this easier I downloaded a heap of SDK's from Microsoft for their documentation. I have taken the SetDlgItemText from another post that I made and attempted to use it. I found all the information on it but I seem to be having a problem. Here is what I did with it:
    Code:
    SetDlgItemText(DLG_MAIN, IDC_STATUS, "Completed...");
    ...but I now get this error about my dialoge box:
    Code:
     error C2664: 'SetDlgItemTextA' : cannot convert parameter 1 from 'const int' to 'struct HWND__ *'
    ...I put all of the parameters in the right places just like it said here:
    Code:
    BOOL SetDlgItemText(
      HWND hDlg,         // handle to dialog box
      int nIDDlgItem,    // control identifier
      LPCTSTR lpString   // text to set
    );
    Does anybody know what's going on?

    (I hopfully wont have this many problems with windows soon becuase I'm going to buy a good windows programming book in like 2 or 3 days)

    You're passing the dialog's ID rather than it's handle. I think that's it.

    Get the handle to the control with GetDlgItem() and pass it as the first parameter.

    another thing...

    when I pass hDlg as the first parameter, it says that it is undeclared when it is actually declared here:
    Code:
    BOOL CALLBACK APP_DlgProc(HWND hDlg, UINT uiMsg, WPARAM wParam, LPARAM lParam)

    Well, when a function is looking for a certain type (which is always the case), you must typecast so that it can do the proper conversions.
