Problem with Dialog Box

I'm making a DialogBox using DialogBoxIndirect() and when I close the dialog window the entire application closes.

Is there a reason why EndDialog() would close the entire application? If there is what would cause it? If not what could be the problem?

Thanks,
Joe

I haven't tried it before, but it might be possible that EndDialog() is being passed the HWND to your main window? I could be wrong but it might be able to destroy normal window. Correct me please if I am.

Thats the only guess I could come up with based on info provided.

Why not post some code so we can take a look and try to actually see whats going on?

I have checked if EndDialog() is getting the handle of the main window and it is not. I even tried forcing the handle of the main window in EndDialog() and it didn't do anything

I didn't include this code because I thought it might complicate things. Any variables that are not defined are defined in the cWINDOWS class.

Code:

---

class cDIALOG: public cWINDOW
{
private:
        static cDIALOG        *Me;
        static cSTRING        *sCaption;       

        static BOOL CALLBACK DlgProc(HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam);
public:
        ~cDIALOG()
        { Close(); }

        int Create(HWND hParent, cSTRING sCaption,
                                int cx, int cy, int x=0, int y=0,
                                DWORD dwStyle=0, DWORD dwExStyle=0);

        void Close(int nResult=0)
        { ChildWindow.ForEach(del_all); ChildWindow.Clear(); EndDialog(hwnd, nResult); }
//ChildWindow is a linked list structure. This structure has been tested and it work correctly

        void OnCreate(void (*Function)())
        { WindowEvents[0].unEvent=WM_INITDIALOG; WindowEvents[0].Function=Function; }
};

Code:

int cDIALOG::Create(HWND hParent, cSTRING sCaption,
                                        int cx, int cy, int x, int y,
                                        DWORD dwStyle, DWORD dwExStyle)
{
        HGLOBAL                        hGlobal;
        LPDLGTEMPLATE        Dlg;
        cDIALOG                        *PrevDlg=Me;
        cWINDOW                        *PrevObj=Objects;

        if ( !(hGlobal=GlobalAlloc(GMEM_ZEROINIT, 1024)) )
                return -1;

        Dlg=LPDLGTEMPLATE(GlobalLock(hGlobal));

        Dlg->cdit=0;
        Dlg->cx=cx;
        Dlg->cy=cy;
        Dlg->dwExtendedStyle=dwExStyle;
        Dlg->style=dwStyle;
        Dlg->x=x;
        Dlg->y=y;

        GlobalUnlock(hGlobal);
        Me=this; //Incase there are more than one dialog box created
        Objects=this; //The objects on the window that can be create are subclassed and the sub-class function needs to be static
        this->sCaption=&sCaption;
        int nReturn=DialogBoxIndirect(AppInstance, Dlg, hParent, DlgProc);
        Me=PrevDlg; //restore old window's handle
        Objects=PrevObj; //restore old object's address
        GlobalFree(hGlobal);

        return  nReturn;
}

Code:

BOOL CALLBACK cDIALOG::DlgProc(HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
        if ( message==WM_INITDIALOG )
                Me->SetText(*sCaption);
       
        cCHILDWINDOW **TempChild;
        cLINKEDLIST<cCHILDWINDOW*> *ChildWindow=&Me->ChildWindow;

        ChildWindow->StepReset();
        while ( (TempChild=ChildWindow->GetNode()) )
        {
                if ( (*TempChild)->ProcessParent(hwnd, message, wParam, lParam) )
                        return 0;
               
                ChildWindow->StepNext();
        }

        if ( Me->ProcessEvents(hwnd, message, wParam, lParam) )
                return 1;
       
        else if ( message==WM_CLOSE )
                Me->Close();

        return 0;
}

Any help would be greatly appreciated

Sorry, I can't. I've never bothered to learn C++ yet. Waiting till I master C before I move on.
