分享如何控制MessageBox的弹出位置
由于某种需要,我不希望调用MessageBox的时候弹出的消息窗口在父窗口的正中,而是自己指定位置
要怎么办啊,
其实我就是想控制这个消息窗口,比如改改它的大小,风格等等
哪位大校能帮忙啊?
MessageBox("msg", "title", MB_OK);

感谢pomelowu(羽战士)
如果我不知道hook的用法
你能写的在具体点吗?比如我想创建一个在屏幕(0,0)位置弹出,大小为100*100的msgbox
要如何做啊?
我在你的代码上这样做,但大不到效果,可能是因为hwnd是null吧
那要怎样做呢?
switch(nCode)
{
case HCBT_ACTIVATE:
// customize the messagebox as your wish
SetWindowpos( hwnd, NULL, 0, 0, 100, 100, NULL );
return 0;
}

There's no other way other than hooks.
If you install a CBT_HOOK, you only hook window
creation, activation etc (in other words, not many
messages). But, it's enough to do whatever customization
you want.

hook WH_CBT
3.WH_CBT 钩子 （一般用于设定窗口位置和修改按钮文本）
a)设定窗口的位置（http://support.microsoft.com/default.aspx?scid=kb;en-us;180936）
HHOOK hHook;
LRESULT CALLBACK CBTProc(int nCode,WPARAM wParam,LPARAM lParam)
{
if(nCode == HCBT_ACTIVATE)
{
RECT rect;
GetWindowRect(hWnd, &rect);
MoveWindow((HWND)hWnd, 0, 0, rect.right-rect.left, rect.bottom-rect.top, TRUE);
}
return CallNextHookEx(hHook, nCode, wParam, lParam);
}
使用方法
hHook = SetWindowsHookEx(WH_CBT, CBTProc, GetModuleHandle(NULL), 0);
MessageBox(NULL, "hello world!", "info", MB_OK);

最好就自己重寫一個MessageBox, 又不是難, 用MFC可以直接插入, 用Win32API都只是:
BOOL CALLBACK MyMessageBoxProc(HWND hDlg, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
switch (uMsg)
{
case WM_INITDIALOG:
MoveWindow(hDlg, x, y, width, height, TRUE);
break;
case WM_COMMAND:
EndDialog(hDlg, LOWORD(wParam));
}
return FALSE;
}
在WinMain中
DialogBox(hInstance, MAKEINTRESOURCE(IDD_MESSAGEBOX), GetDesktopWindow(), MyMessageBoxProc);
