I am creating a window with the Dev-C++ compiler. I know that the code for this comes built in but I learn better if I type it out. The thing is, after I copied it and created a new project, deleted the code and inserted my own....it compiled but the window did not show up. Is this normal? Here is the code I copied:
Code:
#include <windows.h>
/* Declare windows procedure */
LRESULT CALLBACK WindowProcedure ( HWND, UINT, WPARAM, LPARAM);
/* Make the class name into a global variable */
char szClassName[] = "WindowsApp";
int WINAPI WinMain (HINSTANCE hThisInstance,
HINSTANCE hPrevInstance,
LPSTR lpszArgument,
int nFunsterStil)
{
HWND hwnd; /* This is the handle for our window */
MSG messages; /* Here messages to the application are saved */
WNDCLASSEX wincl; /* Data structure for windows class */
/* The Windows Sturcture */
wincl.hInstance = hThisInstance;
wincl.lpszClassName = szClassName;
wincl.lpfnWndProc = WindowProcedure; /* This function is called by windows */
wincl.style = CS_DBLCLKS; /* Catch double clicks */
wincl.cbSize = sizeof (WNDCLASSEX);
/* Use default icon and mouse-pointer */
wincl.hIcon = LoadIcon (NULL, IDI_APPLICATION);
wincl.hIconSm = LoadIcon (NULL, IDI_APPLICATION);
wincl.lpszMenuName = NULL; /* No Menu */
wincl.cbClsExtra = 0; /* No extra bytes after the windows class */
wincl.cbWndExtra = 0; /* Structure or the window instance */
/* Use windows's default background color */
wincl.hbrBackground = (HBRUSH) COLOR_BACKGROUND;
/* Register the window class, if it fails quit the program */
if (!RegisterClassEx (&wincl))
return 0;
/* The class is registered, let's create the program */
hwnd = CreateWindowEx (
0, /* Extended possibilites for variation */
szClassName, /* Classname */
"My Cute Window", /* Window Title */
WS_OVERLAPPEDWINDOW, /* default window */
CW_USEDEFAULT, /* Windows decides the position */
CW_USEDEFAULT, /* where the program is at on the screen */
544, /* Program width */
375, /* the height in pixels */
HWND_DESKTOP, /* The window is a child window of the desktop */
NULL, /* No Menu */
hThisInstance, /* Program Instance handler */
NULL /* No Window creation data */
);
/* Make the window visible on the screen */
ShowWindow (hwnd, nFunsterStil);
/* Run the message loop. It will run until GetMessage() return 0 */
while (GetMessage (&messages, NULL, 0,0))
{
/* Translate virtual-key message into character messages */
TranslateMessage(&messages);
/* Send message to WindowsProcedure */
DispatchMessage (&messages);
}
/* The program return-value is 0 - The value that PostQuitMessage() gave */
return messages.wParam;
}
/* This function is called by the Windows function DispatchMessage() */
LRESULT CALLBACK WindowProcedure (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
switch (message) /* handle the messages */
{
case WM_DESTROY:
PostQuitMessage(0); /* send a WM_QUIT to the message queue */
break;
default: /* For messages we done deal with */
return DefWindowProc (hwnd, message, wParam, lParam);
}
return 0;
}
