Is there a known character limit in textboxes in c# winform applications with MaxLenght set to 0 ?

Thanks, Hans

Answer 1

Win32 documentation says:

Before EM_SETLIMITTEXT is called, the default limit for the amount of text a user can enter in an edit control is 32,767 characters.

For single-line edit controls, the text limit is [...] 0x7FFFFFFE (2147483646) bytes

TextBoxBase.MaxLength documentation confirms this:

The number of characters that can be entered into the control. The default is 32767.

If the MaxLength property is set to 0, the maximum number of characters the user can enter is 2147483646 [or 32,766 on Windows ME,] or an amount based on available memory, whichever is smaller.
