Set text limit in an Edit Control

[BillHart]

I want to limit the text in an Edit Control but don't see how I would obtain the handle of that edit control (see hWndControl in the code below), so as to be able to use SendMessage.
I do see the edit control with an ID of IDC_EDIT1 in the properties pane. Am using Visual C++ out of Visual Studio.Net.


HWND hWndControl;
int lResult;
lResult =SendMessage( hWndControl, EM_SETLIMITTEXT, 2,0);

There is already a message from the edit control when the value in the edit changes - pick this up and check the length of the string in the box

No point in re-inventing the wheel

BillHart,

If you are using MFC you can set the maximum number of characters in an edit control at design time in classwizard for the membervariables tab.
