An application sends an EM_REPLACESEL message to replace the current selection in an edit control with the specified text.
EM_REPLACESEL
fCanUndo = (BOOL) wParam ; // flag that specifies whether replacement can be undone
lpszReplace = (LPCTSTR) lParam ; // pointer to replacement text string
Parameters
fCanUndo
Value of 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.
lpszReplace
Value of lParam. Points to a null-terminated string containing the replacement text.
Return Values
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 current selection, the replacement text is inserted at the current location of the caret.
