Windows编程：遍历程序使用的动态链接库(dll) 代码(C++)

遍历程序使用的动态链接库(dll), 首先需要遍历所有进程, 匹配进程名称与进程ID, 然后根据进程名称, 输出所有使用的库(dll).

示例中Image.exe是预先启动的程序. 代码包含遍历进程的代码, 和输出动态链接库(dll)的代码.

代码:

    CloseHandle(hProcessSnap);  
    return true;

    std::map<std::string, int> nameID;

        return false;  
    }  
    MODULEENTRY32 module32;  
    module32.dwSize = sizeof(module32);  
    BOOL bResult = Module32First(hModuleSnap, &module32);  
    int num(0);  
    while(bResult){  
        std::wcout << "[" << num++ << "] : " <<"Module:" << std::left << std::setw(25)

        bResult = Module32Next(hModuleSnap, &module32);  
    }  
    CloseHandle(hModuleSnap);  
    return true;  
}  
int main()  
{  
    const std::string program("Image.exe");

输出:
