MS Excel allows users to do event programming, usable within VBA code. An event is the action which gets started either by some other VBA code or any user action. Using them, user’s actions and changes in the application state can be monitored and along with it, the suitable action can be taken as a response of certain user actions. This tool was first introduced in Excel 97 and remains the same through 2007.
But the problem starts when the user events don’t get any response. MS Excel 2002 may stop acting to these events. Basically, the problem arises when these events switch to asynchronous behavior. When you drop events for COM component and then call Calculate function on the Excel worksheet from the event, the results may not come as expected.
But, in the severe chances it may bring corruption to the file and cause error messages like:
“Microsoft Excel has encountered a problem and needs to close. We are sorry for the inconvenience.”
The problem starts from a complex worksheet, which is being worked upon by the Calculate function. Now, if while the process application runs in background and foreground window then moves across the application window, it may stop responding. During the process, the calculation starts picking messages from queue and then an asynchronous event is allowed to trigger. As the last COM event and calculation hasn’t completed yet, the next call may cause corruption, which may ask for excel repair.
Excel Repair
Such corrupted worksheets can be repaired and can then be safely restored by excel recovery applications. These are the tools which are programmed to scan the corrupt worksheets through powerful set of algorithms.
Stellar Phoenix Excel Recovery uses the most powerful scanning algorithms which proves helpful to repair and restore the corrupted worksheets. This Excel recovery application supports MS Excel 2007, Excel 2003, Excel 2002 (XP) and Excel 2000.
