vc读取向.exe发送的参数

 

调用某个.exe文件

CString path,strSaveFile;
 ::GetModuleFileName(NULL,path.GetBuffer(MAX_PATH),MAX_PATH);
 path.ReleaseBuffer();
 path = path.Left(path.ReverseFind('\\'));
 strSaveFile.Format("%s\\update.exe",path);

 CString strCmdParam;
 strCmdParam.Format("%s %.3f %s\\up\\update.ini|stard",theHostParam.m_strAppTitle,theHostParam.m_fAppVer,CMainFrame::m_taiShanDoc->m_SystemInitData.NetAddr);
 ::ShellExecute( m_hWnd, "open", strSaveFile, strCmdParam, NULL, SW_SHOWNORMAL);

 

update.exe端接收strCmdParam参数:

 

1:/*CString   x;  
 x.Format("%d,     %s,     %S,     %s",__argc,__argv[1],__argv[2],__argv[3]);  
 MessageBox(x);  
 */
 CString x;
 x.Format("%s",__argv[3]);
 int n=x.ReverseFind('|');
 x = x.Right(x.GetLength()-n-1);
 AfxMessageBox(x);

 

2:

CCommandLineInfo cmdInfo;
ParseCommandLine(cmdInfo);
cmdInfo.m_nShellCommand = CCommandLineInfo::FileNew;
 
CString strFileName=cmdInfo.m_strFileName;
//AfxMessageBox(UserID);
//strFileName="JnwInsideInfo.exe     |20082008";
int ipos=strFileName.ReverseFind('|');
if(ipos>-1)
{
 g_UserID=strFileName.Right(strFileName.GetLength()-(ipos+1));
  //AfxMessageBox(g_UserID);
}
