EM_EXLIMITTEXT message

Sets an upper limit to the amount of text the user can type or paste into a rich edit control.

Parameters

wParam

This parameter is not used; it must be zero.

lParam

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

This message does not return a 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.
