Hai vbk,

if you have the HWND, try the following lines of code to get the text from that window ...
 
CString strWindowText;
char szText[255];
::SendMessage(HWND, WM_GETTEXT, 255, (LPARAM)szText);
strWindowText = szText;

Hope It will help you.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

GetWindowText() would be better than SendMessage().  It will be much faster and far simpler.  (SendMessage() will require a thread context switch among other things.)

But syntaxe of GetWindowText is
int GetWindowText(

    HWND hWnd,      // handle of window or control with text
    LPTSTR lpString,      // address of buffer for text
    int nMaxCount       // maximum number of characters to copy
   );

it return error sometimes

The last parameter is the size of the buffer that the name is to be placed in.  If this size is too small, the name will be truncated to fit the buffer.  Just create a longer buffer and specify a longer length in the last parameter.

>> it is same like on Visual C++.isn't it?
API functions are part of windows.  They don't have anything to do with a particular compiler manufacturer or a particular language.  i.e. GetWindowText() works the same in assembly, C, basic, Pascal etc.  Its not part of any language.
