利用GetModuleFileName得到当前程序运行路径；
原型：
1 WINBASEAPI
2 DWORD
3 WINAPI
4 GetModuleFileNameW(
5 __in_opt HMODULE hModule,
6 __out_ecount_part(nSize, return + 1) LPWCH lpFilename,
7 __in DWORD nSize
8 );
头文件：WinBase.h
2 DWORD
3 WINAPI
4 GetModuleFileNameW(
5 __in_opt HMODULE hModule,
6 __out_ecount_part(nSize, return + 1) LPWCH lpFilename,
7 __in DWORD nSize
8 );
实例：
1 WCHAR path[MAX_PATH];
2 char chpath[MAX_PATH];
3
4 GetModuleFileName(NULL,path,sizeof(path));
5
6 wcstombs(chpath,path,MAX_PATH);
7 std::cout<<chpath<<std::endl;
2 char chpath[MAX_PATH];
3
4 GetModuleFileName(NULL,path,sizeof(path));
5
6 wcstombs(chpath,path,MAX_PATH);
7 std::cout<<chpath<<std::endl;
