Hi, In an MFC application, I have several text edit controls that are monitored (through the EN_CHANGE event / ON_EN_CHANGE handler) to immediately update some output values. However, as a result of a change of one field, I may have to 'automatically' change the content of another field. To avoid any callbacks (and potentially infinite recursion), I would like to be able to set the contents of a text edit field without triggering the ON_EN_CHANGE callback of the containing dialog. Do you know of a proper way to do so ? An approach I could think of is to temporarily change the parent of the text field (e.g. to NULL), but it's kind of ugly. Any other ideas ? Thanks, Ivan
