本文实例讲述了C++实现查壳程序代码,分享给大家供大家参考。具体方法分析如下:
一般来说,PEID是基于特征码的,用python只需要两行代码,用VC实现用了这么多代码……。
python中只要引入pefile模块,第一句代码指定数据库文件,第二句代码返回结果。具体的看pefile官方介绍吧
下面是C++的代码:
代码如下:
void CMyPeidDlg::OnBnClickedBtnOpen()
{
// 获取当前工作路径
CString strAppName;//当前工作目录
::GetModuleFileName(NULL, strAppName.GetBuffer(_MAX_PATH), _MAX_PATH);
strAppName.ReleaseBuffer();
int nPos = strAppName.ReverseFind('//');
strAppName = strAppName.Left(nPos + 1);
// AfxMessageBox(strAppName);
// 文件扩展名过滤器
LPCTSTR szFilter = "EXE Files (*.EXE)|*.EXE|DLL Files (*.DLL)|*.DLL|All Files (*.*)|*.*||";
//初始目录是c:/windows, 初始选择的文件名是test,初始后缀过滤器是 Chart Files (*.xlc)
CFileDialog dlg(TRUE,NULL ,strAppName.GetBuffer(_MAX_PATH) ,OFN_ENABLESIZING ,szFilter,NULL);
if(dlg.DoModal() == IDOK)
{
CString strFile = dlg.GetPathName(); // 全路径
GetDlgItem(IDC_EDT_FILE)->SetWindowText(strFile.GetBuffer(_MAX_PATH));
TRACE("/n&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&/n");
TRACE(strFile);
TRACE("/n&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&/n");
}
}
