Windows app

[SomethinCool]

I have a question..and it's kind of stupid but, i am just starting out. How do you make a windows app? I have the windows.h header file and i dont know a lot about C++. I am using a program called Dev-C++. If you want it, it's 7.56 MB at www.bloodshed.net. So, how do you print words and input things in a windows app? could someone please help me? does anyone know a good C++ code web site that i could go to that teaches me C++ for Win32 apps? thanks.

I have used dev-C++ for about a month. it is very good compiler because it is free. When you go the

File>New

Select "Windows Application" or something like that. It will automatically put the code for you. New you just run the program and you will see an empty gray window. If you want to learn more windows programming then this site would be really helpful:

www.winprog.org

If you don't know how to program in dos then I suggest that don't move on to windows programming. You must understand to concepts of:

pointers
refrences
classes
windows API

and some basics of C++ such as looping switching, etc., I have been programming in windows for just one week but I have spent about a month in DOS programming. If you have any other question then just reply to this thread again. And also stick to this forum. It would be really helpful.

Good Luck!!

As abdul said you must understand to concepts of:

pointers
refrences
classes
windows API

first and then try

Code for basic windows app

1. open visual c++
2. File > New
3. Click Projects tab
4. click Win32 Application and give it a name
5. click finish
6. click the File View Tab on TreeView
7. go to File > New
8. in the first tab Click C++ Source File and name it
9. Copy and paste the code in the new file
10. right click the Header folder and add Windows.h
11. click execute

#include <windows.h>
LRESULT CALLBACK WindowFunc(HWND, UINT, WPARAM, LPARAM);
char szWinNamw[] = "MyWin";
int WINAPI WinMain(HINSTANCE hThisInst, HINSTANCE hPrevInst,
				LPSTR kposzArgs, int nWinMode)


    {
    	HWND hwnd;
    	MSG msg;
    	WNDCLASSEX wcl;
    	wcl.cbSize = sizeof(WNDCLASSEX);
    	wcl.hInstance = hThisInst;
    	wcl.lpszClassName = "My Window";
    	wcl.lpfnWndProc = WindowFunc;
    	wcl.style = 0;
    	wcl.hIcon = LoadIcon(NULL, IDI_APPLICATION);
    	wcl.hIconSm = LoadIcon(NULL, IDI_WINLOGO);
    	wcl.hCursor = LoadCursor(NULL, IDC_ARROW);
    	wcl.lpszMenuName = NULL;
    	wcl.cbClsExtra = 0;
    	wcl.cbWndExtra = 0;
    	wcl.hbrBackground = (HBRUSH) GetStockObject(WHITE_BRUSH);
    	if(!RegisterClassEx(&wcl)) return 0;
    	hwnd = CreateWindow(
    		"My Window",
    		"Skeleton Window",
    		WS_OVERLAPPEDWINDOW,
    		CW_USEDEFAULT,
    		CW_USEDEFAULT,
    		CW_USEDEFAULT,
    		CW_USEDEFAULT,
    		HWND_DESKTOP,
    		NULL,
    		hThisInst,
    		NULL
    		);
    	ShowWindow(hwnd, nWinMode);
    	UpdateWindow(hwnd);
    	while(GetMessage(&msg, NULL, 0, 0))


        	{
        		TranslateMessage(&msg);
        		DispatchMessage(&msg);
        	}
        	return msg.wParam;
    }
    LRESULT CALLBACK WindowFunc(HWND hwnd, UINT message,
    							WPARAM wParam, LPARAM lParam)


        {


            	switch(message)	{
            	case WM_DESTROY:
            		PostQuitMessage(0);
            		break;
            	default:
            		return DefWindowProc(hwnd, message, wParam, lParam);
            	}
            	return 0;
        }

Also, just some advice. While it's quite lengthly to type up a windows program, and it makes since to simply copy and paste the window creation code, it's a good idea, when learning C++, NOT to do this. You shuld type be familiar and type up the code so you know and understand it. Once you can do this, then it's okay to copy and paste.

Hey Vlatko, can you fix your code? I don't want to have to correct your message loop each time

[Vlatko]

Hey,parksie i knew you were going to say that. Well ok. SomethinCool, replace the

while(GetMessage(&msg, NULL, 0, 0)) {
    TranslateMessage(&msg);
    DispatchMessage(&msg);
}

with

int i;
while(i = GetMessage(&msg, NULL, 0, 0)) {
    if(i == -1) break;
    TranslateMessage(&msg);
    DispatchMessage(&msg);
}

I love being predictable...Nothing personal you understand

I used to do it that way until I read through the PSDK and it said specifically not to do that So I'm just following their advice.

I am very mad at you parksie, you dared to correct me...
