Excel throws exception if cell being edited
I'm at my wits end with this bug.. I'm hoping this is so common, that there is a very simple fix. I have a C++ app that does COM based import/export of data directly from Excel, but I have to think that anyone doing VBA would see this all the time.. All of my calls to Excel to determine current workbook, how many workbooks, current worksheet, how many worksheets, getting/setting cell data all work wonderfully.. *unless* the user was editing a cell in the worksheet.. If the worksheet is left in 'editing mode', almost all of the COM calls will thow an exception, and not return successfully. To get out of 'editing mode', I have tried everything from SendKeys("ENTER") to closing the damn Workbook & reopening it (and switching workbooks, activating, etc etc) The machine either locks up, or just throws more exceptions. I've meticulously gone through excel9.tli and excel9.tlh, looking for some method remotely pertainant, such as a 'deactive' or 'end edit' or anything that would allow the COM automation calls to succeed.. This is so very frustrating, because one very common user action in Excel can bring (the functionality of) my whole app to its knees.. Any help/pointers/direction/solution would be greatly appreciated.. Thank You. -- Pixeled ------------------------------------------------------------------------ Pixeled's Profile: http://www.excelforum.com/member.php...o&userid=26932 View this thread: http://www.excelforum.com/showthread...hreadid=401558 |

Excel throws exception if cell being edited
I haven't tried to do this with automation, but all of us in the VBA sphere
just know that if a cell is being edited then VBA will not function. In most VBA situations, it's hard to get into this position. If VBA is running you can't edit, if editing VBA can't run, so the most typical time that we see this is when scheduling routines to run at a future time. There is no method that I know of that will get you out of edit mode unfortunately. I'd guess you are looking at some kind of control loop in VB that creates a delay and a retry if your call fails. Alternatively, can you do this with another hidden instance of Excel rather than the instance that can be locked up by your users? Or, can you have a launch routine that asks your user if it is ok to run, and an exit message when your code has run. This way if the launch routine fails you don't do anything. I know I'd be annoyed if Excel got hijacked while I was working on something. Robin Hammond www.enhanceddatasystems.com "Pixeled" wrote in message ... I'm at my wits end with this bug..
