根据官方的说法:
For the best results use the following table to convert paths.
Windows 2000 = GetModuleFileNameEx()
Windows XP x32 = GetProcessImageFileName()
Windows XP x64 = GetProcessImageFileName()
Windows Vista = QueryFullProcessImageName()
Windows 7 = QueryFullProcessImageName()
Note: If you are not aware the API GetProcessImageFileName() returns a kernel DOS device path. You can use the following API to map the device paths to a Win32 format.
但要注意的是GetModuleFileName在64bit下获取到的是不正确的，用32去填充64结果是空。本人在32bit的win7下可以准确获取，64bit的win7下得不到自己要的东西。如下图所示:
推荐用vista新增的:QueryFullProcessImageName(),结果入下图:
另外搜遍了网络也没搜到该函数的样例，再懒也只好自己写了～～
DWORD size = MAX_PATH;
char sExeName[MAX_PATH] = {0};
QueryFullProcessImageName(hProcess, 0, sExeName, &size);
当然用GetProcessImageFileName获取更好，只是代码有点长，懒的写了。
