 1. 如何获得运行程序当前所在文件夹地址

char szFolder[1024] = {0};
                ::GetModuleFileName(NULL,szFolder,1024);
                CString Temp = _T(szFolder);
                int pos = Temp.ReverseFind('\\');
                CString StrFolderTemp(szFolder,pos);
                StrFolder.Format("%s",StrFolderTemp); 
       CString StrName="test";
       hMutex=OpenMutex(MUTEX_ALL_ACCESS,FALSE,StrName);
       if(hMutex==NULL){
          hMutex=::CreateMutex(NULL,NULL,StrName);
       }else{
          if(AfxMessageBox("程序实例已经存在",MB_ICONQUESTION|MB_YESNO==IDYES)){
              return FALSE;
            }
       }
void MyFolder::RecursiveDelete(CString Path){
  CFileFind ff;
  CString cPath=Path;
  if(cPath.Right(1)!="\\"){
    cPath+="\\";
  }
  cPath+="*";
  BOOL res=ff.FindFile(cPath);
  while(res){
    res=ff.FindNextFile();
    CString name=ff.GetFilePath();
    if(!ff.IsDots()&&!ff.IsDirectory()){
      DeleteFile(ff.GetFilePath());
    }else if(ff.IsDots()){
      continue;
    }else if(ff.IsDirectory()){
      cPath=ff.GetFilePath();
      RecursiveDelete(cPath);
      RemoveDirectory(cPath);
    }
  }
}
  char *From = "F:\\test.txt\0";
  char *To = "E:\\test.txt\0";
  SHFILEOPSTRUCT op;
  ZeroMemory(&op, sizeof(op));
  op.hwnd = NULL; // 主窗体或应用程序的句柄，允许为NULL
  op.wFunc = FO_COPY; //此处可改变，执行移动功能（FO_MOVE）
  op.pFrom = From;
  op.pTo = To;
  op.fFlags= 0;
  SHFileOperation( &op);
