客户区贴图的问题
这一段玩起了汇编，看到有些注册机异型窗口，就想学一下，从网上找了几篇不过是C的，自己就拿汇编重复一下，可是总有问题，本人也是编程菜鸟，windows消息机制，也是一知半解，汇编也是新手，我把别人教程的C代码，和我写的汇编代码，附上，请高手指点一二
程序代码：/ 对话框位图背景 - WM_CTLCOLORDLG中使用StretchBlt贴图
//By MoreWindows-(http://blog.)
#include <windows.h>
#include "resource.h"
const char szDlgTitle[] = "位图背景 使用StretchBlt贴图 MoreWindows-(http://blog.)";
// 对话框消息处理函数
BOOL CALLBACK DlgProc(HWND hDlg, UINT message, WPARAM wParam, LPARAM lParam);
int APIENTRY WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow)
{
DialogBox(hInstance, MAKEINTRESOURCE(IDD_DIALOG1), NULL, DlgProc);
return 0;
}
BOOL CALLBACK DlgProc(HWND hDlg, UINT message, WPARAM wParam, LPARAM lParam)
{
RECT rcDialog;
HBITMAP hBitmap;
static BITMAP s_bm;
static HDC s_hdcMem;
switch (message)
{
case WM_INITDIALOG:
// 设置对话框标题
SetWindowText(hDlg, szDlgTitle);
// 设置对话框大小可调节
SetWindowLong(hDlg, GWL_STYLE, GetWindowLong(hDlg, GWL_STYLE) | WS_SIZEBOX);
// 加载背影图片
hBitmap = (HBITMAP)LoadImage(NULL, "005.bmp", IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE | LR_CREATEDIBSECTION);
if (hBitmap == NULL)
{
MessageBox(hDlg, "LoadImage failed", "Error", MB_ICONERROR);
exit(0);
}
else
{
// 将背影图片放入HDC - s_hdcMem
HDC hdc;
hdc = GetDC(hDlg);
s_hdcMem = CreateCompatibleDC(hdc);
SelectObject(s_hdcMem, hBitmap);
ReleaseDC(hDlg, hdc);
// 得到位图信息
GetObject(hBitmap, sizeof(s_bm), &s_bm);
}
return 0;
case WM_COMMAND:
switch (LOWORD(wParam))
{
case IDCANCEL:
DeleteDC(s_hdcMem);
EndDialog(hDlg, LOWORD(wParam));
return TRUE;
}
break;
case WM_SIZE:
InvalidateRect(hDlg, NULL, TRUE);
return TRUE;
case WM_CTLCOLORDLG:
GetClientRect(hDlg, &rcDialog);
//通过SetStretchBltMode的设置能使StretchBlt在缩放图像更加清晰
SetStretchBltMode((HDC)wParam, COLORONCOLOR);
StretchBlt((HDC)wParam, 0, 0, rcDialog.right, rcDialog.bottom, s_hdcMem, 0, 0, s_bm.bmWidth, s_bm.bmHeight, SRCCOPY);
return (BOOL)((HBRUSH)GetStockObject(NULL_BRUSH));
}
return FALSE;
}接下来是我用汇编的代码，总是图片出不来程序代码：.386

我把教程中的LoadImage换成了LoadBitmap为了使加载资源中的为图方便经调试WM_CTLCOLORDLG消息总是不会触发，但是用C语言的就正常，难道是偶滴RPWT，……
