EM_REPLACESEL message

Replaces the selected text in an edit control or a rich edit control with the specified text.

Parameters

wParam

Specifies whether the replacement operation can be undone. If this is TRUE, the operation can be undone. If this is FALSE , the operation cannot be undone.

lParam

A pointer to a null-terminated string containing the replacement text.

Return value

This message does not return a value.

Remarks

Use the EM_REPLACESEL message to replace only a portion of the text in an edit control. To replace all of the text, use the WM_SETTEXT message.

If there is no selection, the replacement text is inserted at the caret.

Rich Edit: Supported in Microsoft Rich Edit 1.0 and later. For information about the compatibility of rich edit versions with the various system versions, see About Rich Edit Controls.

In a rich edit control, the replacement text takes the formatting of the character at the caret or, if there is a selection, of the first character in the selection.
