קבצי האדר...
שלום, אני עובד בשפת c++ (דוס) (devcpp)
אני מתחיל כרגע ב winAPI ויש לי קוד שאני לא בניתי....
קוד PHP:
#include <windows.h>
#include "resource.h"
const char g_szClassName[] = "myWindowClass";
HBITMAP g_hbmBall = NULL;
HBITMAP g_hbmMask = NULL;
HBITMAP CreateBitmapMask(HBITMAP hbmColour, COLORREF crTransparent)
{
HDC hdcMem, hdcMem2;
HBITMAP hbmMask;
BITMAP bm;
GetObject(hbmColour, sizeof(BITMAP), &bm);
hbmMask = CreateBitmap(bm.bmWidth, bm.bmHeight, 1, 1, NULL);
hdcMem = CreateCompatibleDC(0);
hdcMem2 = CreateCompatibleDC(0);
SelectObject(hdcMem, hbmColour);
SelectObject(hdcMem2, hbmMask);
SetBkColor(hdcMem, crTransparent);
BitBlt(hdcMem2, 0, 0, bm.bmWidth, bm.bmHeight, hdcMem, 0, 0, SRCCOPY);
BitBlt(hdcMem, 0, 0, bm.bmWidth, bm.bmHeight, hdcMem2, 0, 0, SRCINVERT);
DeleteDC(hdcMem);
DeleteDC(hdcMem2);
return hbmMask;
}
LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
switch(msg)
{
case WM_CREATE:
g_hbmBall = LoadBitmap(GetModuleHandle(NULL), MAKEINTRESOURCE(IDB_BALL));
if(g_hbmBall == NULL)
MessageBox(hwnd, "Could not load IDB_BALL!", "Error", MB_OK | MB_ICONEXCLAMATION);
g_hbmMask = CreateBitmapMask(g_hbmBall, RGB(0, 0, 0));
if(g_hbmMask == NULL)
MessageBox(hwnd, "Could not create mask!", "Error", MB_OK | MB_ICONEXCLAMATION);
break;
case WM_CLOSE:
DestroyWindow(hwnd);
break;
case WM_PAINT:
{
BITMAP bm;
RECT rcClient;
PAINTSTRUCT ps;
HDC hdc = BeginPaint(hwnd, &ps);
HDC hdcMem = CreateCompatibleDC(hdc);
HBITMAP hbmOld = SelectObject(hdcMem, g_hbmMask);
GetObject(g_hbmBall, sizeof(bm), &bm);
GetClientRect(hwnd, &rcClient);
FillRect(hdc, &rcClient, GetStockObject(LTGRAY_BRUSH));
BitBlt(hdc, 0, 0, bm.bmWidth, bm.bmHeight, hdcMem, 0, 0, SRCCOPY);
BitBlt(hdc, bm.bmWidth, 0, bm.bmWidth, bm.bmHeight, hdcMem, 0, 0, SRCAND);
BitBlt(hdc, bm.bmWidth * 2, bm.bmHeight * 2, bm.bmWidth, bm.bmHeight, hdcMem, 0, 0, SRCAND);
SelectObject(hdcMem, g_hbmBall);
BitBlt(hdc, 0, bm.bmHeight, bm.bmWidth, bm.bmHeight, hdcMem, 0, 0, SRCCOPY);
BitBlt(hdc, bm.bmWidth, bm.bmHeight, bm.bmWidth, bm.bmHeight, hdcMem, 0, 0, SRCPAINT);
BitBlt(hdc, bm.bmWidth * 2, bm.bmHeight * 2, bm.bmWidth, bm.bmHeight, hdcMem, 0, 0, SRCPAINT);
SelectObject(hdcMem, hbmOld);
DeleteDC(hdcMem);
EndPaint(hwnd, &ps);
}
break;
case WM_DESTROY:
DeleteObject(g_hbmBall);
DeleteObject(g_hbmMask);
PostQuitMessage(0);
break;
default:
return DefWindowProc(hwnd, msg, wParam, lParam);
}
return 0;
}
int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
LPSTR lpCmdLine, int nCmdShow)
{
WNDCLASSEX wc;
HWND hwnd;
MSG Msg;
wc.cbSize = sizeof(WNDCLASSEX);
wc.style = 0;
wc.lpfnWndProc = WndProc;
wc.cbClsExtra = 0;
wc.cbWndExtra = 0;
wc.hInstance = hInstance;
wc.hIcon = LoadIcon(NULL, IDI_APPLICATION);
wc.hCursor = LoadCursor(NULL, IDC_ARROW);
wc.hbrBackground = (HBRUSH)(COLOR_WINDOW+1);
wc.lpszMenuName = NULL;
wc.lpszClassName = g_szClassName;
wc.hIconSm = LoadIcon(NULL, IDI_APPLICATION);
if(!RegisterClassEx(&wc))
{
MessageBox(NULL, "Window Registration Failed!", "Error!",
MB_ICONEXCLAMATION | MB_OK);
return 0;
}
hwnd = CreateWindowEx(
WS_EX_CLIENTEDGE,
g_szClassName,
"Another Bitmap Program",
WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT, CW_USEDEFAULT, 240, 160,
NULL, NULL, hInstance, NULL);
if(hwnd == NULL)
{
MessageBox(NULL, "Window Creation Failed!", "Error!",
MB_ICONEXCLAMATION | MB_OK);
return 0;
}
ShowWindow(hwnd, nCmdShow);
UpdateWindow(hwnd);
while(GetMessage(&Msg, NULL, 0, 0) > 0)
{
TranslateMessage(&Msg);
DispatchMessage(&Msg);
}
return Msg.wParam;
}
הקובץ שמור תחת השם bmp_two.c
יש עוד קובץ האדר ש"אני צריך לבנות" בשם resource.h (למטה)
קוד PHP:
//{{NO_DEPENDENCIES}}
// Microsoft Developer Studio generated include file.
// Used by bmp_one.rc
//
#define IDB_BALL 101
// Next default values for new objects
//
#ifdef APSTUDIO_INVOKED
#ifndef APSTUDIO_READONLY_SYMBOLS
#define _APS_NEXT_RESOURCE_VALUE 102
#define _APS_NEXT_COMMAND_VALUE 40001
#define _APS_NEXT_CONTROL_VALUE 1000
#define _APS_NEXT_SYMED_VALUE 101
#endif
#endif
הקובץ שמור תחת השם resource.h אבל הקוד לא עובד אני חושב שיש בעיה שהמהדר לא מזהה את הקובץ.
פתחתי פרוייקט של windows application ועכשיו זה כותב לי שגיאות:
C:\Documents and Settings\user\ùåìçï äòáåãä\nnn\Untitled1.c In function `LRESULT WndProc(HWND__*, UINT, WPARAM, LPARAM)':
61 C:\Documents and Settings\user\ùåìçï äòáåãä\nnn\Untitled1.c invalid conversion from `void*' to `HBITMAP__*'

תודה מראש,
