Parameters
-
wParam

Specifies the maximum amount of text that can be entered. If this parameter is zero, the default maximum is used, which is 64K characters. A COM object counts as a single character.
Return value

Remarks
The text limit set by the EM_EXLIMITTEXT message does not limit the amount of text that you can stream into a rich edit control using the EM_STREAMIN message with lParam set to SF_TEXT. However, it does limit the amount of text that you can stream into a rich edit control using the EM_STREAMIN message with lParam set to SF_RTF.
Before EM_EXLIMITTEXT is called, the default limit to the amount of text a user can enter is 32,767 characters.
