Craig, short time before I answered a similar question in a French newsgroup by copying (and translating) a former post of mine. Here a copy of the English text: ------------------- {See corel.wpoffice.paradox-opal, Disable the wheel on a mouse? 28. April 2004 15:39} Paul, I know the same problem and its really bothering, if you change a record without intention. The same thing happens to me when scrolling in internet-forms with the mouse wheel. I do understand your concerns. Nevertheless I would agree with Jim. Disabling the wheel function may appear as a weakness of your app for the costumer. So it's better to distinguish, which field is active and to chose the best action (setting the event you like and disable the default or use setErrorCode(userError). This does not apply to actions fired by key-pressing. But to all menu-actions, this means also clicks on icons in the toolbar, are involved. Please note: The wheel-move triggers first an menuAction event. Here you can use some method to decide what to do. For example: I do redirect the NextRecord to FieldForward in some critical cases. method menuAction(var eventInfo MenuEvent) var siID smallInt uiActive uiObject stAName string endVar if eventInfo.isPreFilter() then ;// This code executes for each object on the form siID=eventInfo.ID() if (siID=MenuRecordNext OR siID=MenuRecordPrevious) then stAName=active'name view("Wheel or not wheel, that is the question!",stAName) switch case stAName="myField": ;do something case stAName="yourField": ;do something different ;... endSwitch ; Code here endIf else ;// This code executes only for the form endIf endMethod HTH Egbert -- _______________________________ Babst, Institutionsberatung, BabstSoft e.K.

If I have a form of many records (1 record per page). How do I prevent the user from scrolling to another existing record using the mouse scroll button. I know how to intercept keyboard stuff, just not mouse scrolling. Thanks, Craig Futterman |
