请问在ATL控件如何获得应用程序实例句柄？
我用AfxGetApp()->m_hInstance方法在运行总会出错，有没有其他办法应用程序实例句柄啊，或者告诉我该怎么改。
说明：我要在控件中加载光标，LoadCursor()方法中要用这个实例句柄。

[masterz]

use GetModuleFileName to retrieve file name of the host application,
The GetModuleHandle function retrieves a module handle for the specified module if the file has been mapped into the address space of the calling process.

呵呵,THK U,我已经知道了_pModule->GetModuleInstance();来获取应用程序实例句柄，不过我还是很感谢你，还想再问一个问题，为什么用SetCursor()设定一个32X32的光标可以显示，但是设定一个系统光标或者显示一个自己做的16X16的光标就是不能显示呢？

23. I've created a 16x16 icon for my app. Why does Windows insist on squishing up the 32x32 version ?


You've created an MFC app. Taking a dialog-based app as an example, look at the source for your main window(dialog) and check out the constructor. You'll see this:

m_hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME);

But LoadIcon can only load icons which are SM_CXICON x SM_CYICON pixels big, which is nearly always the 32x32 version. When it needs a 16x16 version, such as for your titlebar, it squishes that up. Yuck. Instead, replace the code above with this :

m_hIcon = (HICON) LoadImage (AfxGetInstanceHandle(),
MAKEINTRESOURCE(IDR_MAINFRAME),
IMAGE_ICON,
16, 16,
LR_DEFAULTCOLOR);

I know, because I forget to call ShowCursor function

Present the Score THK U!
