Handle the EN_UPDATE notification in the parent dialog box.
The notification is sent in the form of a WM_COMMAND message.
In this handler, the edit box text can be retrieved and manipulated.

Another thing you can do is to let the user type the space key and then use Trim() function once you acquire the data from your edit box. I think you are more interested in getting the string without the spaces, than not to allow the user to enter spaces.
You need to google first, if you have "It's urgent please" mentioned in your question.

If you just want the string without spaces in the staring and ending, then you can use the CString::TrimLeft and CString::TrimRight.
But if you need to prevent it from entering itself, then you need to map the EN_CHANGE and watch the input and filter it. This might be simple.

To move the cursor use
edit.SetSel( nPos, nPos )

Well...
CString csStr = _T( " Some text with spaces... " );
csStr.TrimLeft();
csStr.TrimRight();
Have a look at MSDN also...

The idea of using TrimLeft/Right is that you can then let the user enter spaces if she like. Later, when you get the text from the edit box for use, you can just throw the spaces away.
It's a choise. Trimming later will be less confusing for the user, and less work for you.
I know if I wanted to enter text in a box, and my keyboard suddenly looked like it stopped working, I would be concerned...

I saw that question. I replied telling you (politely) that you're being thick, and should do things in a different way, as you had already been shown.

that function is not supported in EVC++.

Are these not the right ones?
CreateFile()
