Hello, i've created an edit field, but it can't contain an unlimited amount of chars. The width of the edit field is the max number of chars, how can i make this go away so that it can contain as many chars as i want?

In this sample, the bold line makes the edit control to use unlimited memory for the text that can be contained by the control: CEdit::Create(
WS_CHILD|WS_VISIBLE|WS_TABSTOP
|ES_AUTOHSCROLL|ES_AUTOVSCROLL
|ES_LEFT
|(isMultiline?ES_WANTRETURN|ES_MULTILINE/*|WS_HSCROLL*/|WS_VSCROLL:0)
,rcCtl,pParent,IDC_EDIT_BOX + (++count));
CEdit::SetLimitText(0);Regards,

That won't solve his problem... since Multiline Edit control will also limit the buffer size by default.

@vivendi: Another way of changing the behaviour of the control, using only APIs (no MFC derived class), would be to send EM_SETLIMITTEXT message to the control (using SendMessage API). Give both wParam & lParam as 0 (zero) in order to disable max_characters check.

Well, everything has a limit.
The max limit that can be set (by passing zero in wParam when sending EM_SETLIMITTEXT/EM_LIMITTEXT message) depends on edit type (single or multiline) and the operating system

Windows 95/98

0x7FFE for single line edit control
0xFFFF for multiline edit control

Windows NT/2000/XP

0x7FFFFFFE for single line edit control
0xFFFFFFFF for multiline edit control


If you want to step beyond these limits use rich edit control.

Just use the ES_AUTOHSCROLL style.
