Dialogs

Well after a couple of years doing dialog box, buttons, listviews, etc the hard way (ie CreateWindowEX), I have decieded to move on.

I guess the first question is I still want to use as much pure Win32/API as possible (no MFC) so is using the resource editor and Dialog or CreateDialog the best way to do this?

My second question is how do I do it? I make a quick dialog using an IDD_PROPAGE_MEDIUM. Now I am trying to get it to just come up. I have tried CreateDialog() and Dialog() with out any luck. Someone want to help me out?

Doing this I get a NULL g_hWnd

Code:

---

/*---------------------------------*/
                                //Include

#include "Main.h"

/*---------------------------------*/
                                //Global VARs

HWND                g_hWnd;                                                        //Holds The Window Handle

HINSTANCE        g_hInst;                                                //Holds The Window Instance

TCHAR                g_szClass[]                = "Test Window";//Class Title

HANDLE                g_hMutex                = NULL;                        //Handle For The Mutex

/*---------------------------------*/
                                //Modual VARs

int m_iWidth        = 500;                                                //Main Window Width
int m_iHeight        = 500;                                                //Main Window Height
int m_iX                = CENTERX(m_iWidth);                //Main Window's X Position
int m_iY                = CENTERY(m_iHeight);                //Main Window's Y Position


/*---------------------------------*/
                                //Modual Functions

BOOL CALLBACK DialogProc(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam);

/*---------------------------------*/

{

        MSG _msg;                                                                                //VAR To Hold Our Main Messages

        if(!Startup(g_szClass))                                                        //Run My Custom Start Function
                return -1;

        g_hWnd = CreateDialog(hInst, MAKEINTRESOURCE(IDD_MAIN), NULL, DialogProc);
       
        ShowWindow(g_hWnd, SW_SHOW);
        int i;
        while(i = GetMessage(&_msg, NULL, 0, 0))                //Window Message Loop
        {
                if (i == -1)
                        break;

                TranslateMessage(&_msg);
                DispatchMessage(&_msg);
        }

        return ((int)_msg.wParam);                                                //Exit The Program

}






/*###########################################################################################*/

BOOL CALLBACK DialogProc(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
        switch(uMsg)
        {
                case WM_INITDIALOG:
                        return TRUE;
                case WM_CLOSE:
                        DestroyWindow(hWnd); //Closes the dialog box
                        PostQuitMessage(0);  //Exit the program
                return TRUE;

        }
        return FALSE;
}

If I use Dialog instead I can get the window to come up, but if I even try to click on it I cant. Its like its not being drawn/redrawn. So I am stuck.

Any help would be great thanks.

Dialog? Do you mean DialogBox?

The code actually looks ok to me, I don't see why it shouldn't be working.

Yeah DialogBox, sorry.

I don't get it either, from what I can tell it SHOULD work too, which is why this is starting to get frustrating. All I wanted to do was make Windows faster instead of having to code everything by hand :mad:

Ok so if I use GetDesktopWindow() instead of NULL:
CreateDialog(g_hInst,MAKEINTRESOURCE(IDD_MAIN),GetDesktopWindow(),Main_DlgProc);

I get a window like DialogBox gives me, but I can't click on it or anything (See attached)

Ok I got it stupid POS. I had to change:

Code:

---

        int i;
        while(i = GetMessage(&_msg, NULL, 0, 0))                //Window Message Loop
        {
                if (i == -1)
                        break;

                if(!IsDialogMessage(g_hWnd,&_msg))
                {
                        TranslateMessage(&_msg);
                        DispatchMessage(&_msg);
                }
        }

Also for some REASON .NET 2003 has the dialog disabled by default. Oh well it looks like it is working now.

Oh yeah, the special message loop...

Never actually used it (I used dialogs only in MFC), but I read of it in the Petzold. Probably would have never thought of it.
