分享在应用程序中调用 GetModuleHandle(NULL), 返回 0x00000042 疑问?
为什么调用这个 GetModuleHandle(NULL) 返回的值这么怪异是 0x00000042
不是 AfxGetApp()->m_hInstance ?
不是 AfxGetApp()->m_hInstance ?

GetModuleHandle:获取一个应用程序或动态链接库的模块句柄，不一样的话是不是在动态库中调用的？

GetModuleHandle(NULL)
是在主窗口调用的， 照理应该返回 AfxGetApp()->m_hInstance 吧

GetModuleHandle Function
Retrieves a module handle for the specified module. The module must have been loaded by the calling process.
To avoid the race conditions described in the Remarks section, use the GetModuleHandleEx function.
Syntax
HMODULE WINAPI GetModuleHandle(
__in_opt LPCTSTR lpModuleName
);
Parameters
lpModuleName
The name of the loaded module (either a .dll or .exe file). If the file name extension is omitted, the default library extension .dll is appended. The file name string can include a trailing point character (.) to indicate that the module name has no extension. The string does not have to specify a path. When specifying a path, be sure to use backslashes (\), not forward slashes (/). The name is compared (case independently) to the names of modules currently mapped into the address space of the calling process.
If this parameter is NULL, GetModuleHandle returns a handle to the file used to create the calling process (.exe file).

0x00000042 是零区，不可能是一个模块的加载地址
调试确认一下。
