C++에서는 컴퓨터에 .Net 환경이 있는지 확인합니다.

可以判应用程序文件夹下是否有.net环境的文件夹来解决。

Cpp代码 

int main(int argc, char* argv[])  
{  
    char winDir[256]={0};  
    GetWindowsDirectory(winDir, 256);  
    //strcat(winDir,"\\Microsoft.Net\\");  
    printf("%s\n",winDir);  
    //test .net exist.  
    char tcProgramFile[MAX_PATH] = {0};  
    SHGetSpecialFolderPath(NULL,tcProgramFile,0x26,0);   
    strcat(tcProgramFile,"\\Microsoft.NET");  
    printf("%s\n",tcProgramFile);  
    HANDLE hFind;  
    WIN32_FIND_DATA FindFileData;  
    hFind = FindFirstFile(tcProgramFile,&FindFileData);  
    if(hFind == INVALID_HANDLE_VALUE)  
    {  
        printf(".Net not exist!\n");  
        exit(1);  
    }  
    else  
    {  
        printf(".Net environment ok!\n");  
    }  
        return 0;  
}
