Hi all,
I want to learn programming C++ for Windows 32 Programs.
I can progamm text based programs.
When i tested the tutorial for Window Programming,
and wrote this Example Code my 2 Compiler`s get Errors.
Because i would not have this Header File.
The first program "Hello World" at the window programming tutorial was no problem for the compilers, but the second one.
I already read in the FAQ that there is no possiblitie that headers can be downloaded. But can be coded by myself.
Is this headerfile "stdafx.h" the same not download able category?
Code:/* Trim fat from windows*/
#define WIN32_LEAN_AND_MEAN
#pragma comment(linker, "/subsystem:windows")
/* Pre-processor directives*/
#include "stdafx.h"
#include <windows.h>
/* Windows Procedure Event Handler*/
LRESULT CALLBACK WndProc(HWND hwnd, UINT message, WPARAM
wParam, LPARAM lParam)
{
PAINTSTRUCT paintStruct;
/* Device Context*/
HDC hDC;
/* Text for display*/
char string[] = "Hello, World!";
/* Switch message, condition that is met will
execute*/
switch(message)
{
/* Window is being created*/
case WM_CREATE:
return 0;
break;
/* Window is closing*/
case WM_CLOSE:
PostQuitMessage(0);
return 0;
break;
/* Window needs update*/
case WM_PAINT:
hDC = BeginPaint(hwnd,&paintStruct);
/* Set txt color to blue*/
SetTextColor(hDC,
COLORREF(0x00FF0000));
/* Display text in middle of window*/
TextOut(hDC,150,150,string,sizeof(string)-1);
EndPaint(hwnd, &paintStruct);
return 0;
break;
default:
break;
}
return (DefWindowProc(hwnd,message,wParam,lParam));
}
/* Main function*/
int APIENTRY WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow)
{
WNDCLASSEX windowClass; //window
class
HWND hwnd;
//window handle
MSG msg;
//message
bool done;
//flag saying when app is complete
/* Fill out the window class structure*/
windowClass.cbSize = sizeof(WNDCLASSEX);
windowClass.style = CS_HREDRAW | CS_VREDRAW;
windowClass.lpfnWndProc = WndProc;
windowClass.cbClsExtra = 0;
windowClass.cbWndExtra = 0;
windowClass.hInstance = hInstance;
windowClass.hIcon = LoadIcon(NULL, IDI_APPLICATION);
windowClass.hCursor = LoadCursor(NULL, IDC_ARROW);
windowClass.hbrBackground =
(HBRUSH)GetStockObject(WHITE_BRUSH);
windowClass.lpszMenuName = NULL;
windowClass.lpszClassName = "MyClass";
windowClass.hIconSm = LoadIcon(NULL, IDI_WINLOGO);
/* Register window class*/
if (!RegisterClassEx(&windowClass))
{
return 0;
}
/* Class registerd, so now create window*/
hwnd = CreateWindowEx(NULL, //extended style
"MyClass", //class name
"A Real Win App", //app name
WS_OVERLAPPEDWINDOW | //window style
WS_VISIBLE |
WS_SYSMENU,
100,100, //x/y coords
400,400,
//width,height
NULL, //handle to parent
NULL, //handle to menu
hInstance, //application instance
NULL); //no extra
parameter's
/* Check if window creation failed*/
if (!hwnd)
return 0;
done = false; //initialize loop condition variable
/* main message loop*/
while(!done)
{
PeekMessage(&msg,hwnd,NULL,NULL,PM_REMOVE);
if (msg.message == WM_QUIT) //check for a
quit message
{
done = true; //if found, quit app
}
else
{
/* Translate and dispatch to event queue*/
TranslateMessage(&msg);
DispatchMessage(&msg);
}
}
return msg.wParam;
}
Please help!
How could i learn when there is no possiblity to compile the code correctly. I`m using Dev-C++ and/or Digital Mars Compiler.
