MFC中判断文件路径

判断路径是否存在，若不存在，则创建

CString namep = _T("e:\\fb\\");
        if(!PathIsDirectory(namep)){
        CreateDirectory(namep,NULL);
        //if create fail,alert message box.
        //MessageBox(L"Cannot create save path!", NULL, MB_OK);
        //return;
    }

 

 拼接string和int

    int imagenum = xxx;//变量
    char* name = "e:\\mtkfb\\bmp";
    char fname[25] = "";int name_index = imagenum;
    sprintf(fname,"%s_%d.bmp",name,name_index);
