1:获得本程序的进程ID
         long gpid; 
        gpid=::wxGetProcessId(); 
        wxString tempWxString; 
        tempWxString.sprintf(wxT( "%d"), gpid); 
        wxMessageBox(tempWxString, _( "Welcome to..."));
 
2:定时器
        ::wxStartTimer(); 
         long gt; 
        gt=::wxGetElapsedTime( true); 
        wxString tempWxString; 
        tempWxString.sprintf(wxT( "is %d second"), gt/1000); 
        wxMessageBox(tempWxString, _( "Welcome to..."));
 
3:一句话COPY文件
//bool wxCopyFile(const wxString& file1, const wxString& file2, bool overwrite = true) 
 
::wxCopyFile( "c:\\README.TXT", "d:\\1.txt", true);
 
4:获得系统文件夹
        wxString osDirectory; 
        osDirectory=::wxGetOSDirectory(); 
        wxMessageBox(osDirectory, _( "Welcome to..."));
 
5:获得系统版本信息
        wxString OsVersion; 
        OsVersion=::wxGetOsDescription(); 
        wxMessageBox(OsVersion, _( "axi Test"));
 
6：窗体坐标
        wxPoint wp; 
        wp=frame->GetClientAreaOrigin(); 
         int x1,y1; 
        x1=wp.x; 
        y1=wp.y; 
        wxString tempWxString; 
        tempWxString.sprintf(wxT( "x: %d y: %d"), x1,y1); 
        wxMessageBox(tempWxString, _( "frame xy"));
 
其他的一些文件操作
::wxRemoveFile 
bool wxRemoveFile( const wxString& file) 
 
Removes file, returning  true  if successful. 
 
 
 

 
::wxRenameFile 
bool wxRenameFile( const wxString& file1,  const wxString& file2,  bool overwrite =  true) 
 
Renames file1 to file2, returning  true  if successful. 
 
If overwrite parameter  is  true ( default), the destination file  is overwritten  if it exists, but  if overwrite  is  false, the functions fails  in  this  case. 
 
::wxRmdir 
bool wxRmdir( const wxString& dir,  int flags=0) 
 
Removes the directory dir, returning  true  if successful. Does not work under VMS. 
 
The flags parameter  is reserved  for future use. 
 
Please notice that there  is also a wxRmDir() function which simply wraps the standard POSIX rmdir() function and so return an integer error code instead of a boolean value (but otherwise  is currently identical to wxRmdir), don't confuse these two functions.
