Dialogs

[Technocrat]

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

/*---------------------------------*/
				//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);

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

int WINAPI WinMain(HINSTANCE hInst, HINSTANCE hPrevInst, LPSTR lpCmdLine, int nCmdShow)
{
/*>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>*/	
	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.

[Technocrat]

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

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)

[Technocrat]

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

	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.

[CornedBee]

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.
