setTimer - causing exception errors?

[ajbeer]

In my VBA code in Excel, I am using the following function to call the Windows API setTimer

Sub StartTimer()
TimerSeconds = 300 ' how often to "pop" the timer.
TimerID = SetTimer(0&, 0&, TimerSeconds * 1000&, AddressOf TimerProc)
End Sub

I have only recently added this to my code. Previously I was just using an Excel timer.

Since changing the code I have had a few exception errors in Excel.

Could using the Windows API timer be causing these errors?

For example, if the Windows timer is not properly stopped (whilst debugging the code), would starting the timer again cause an exception error?

Any help on this would be very much appreciated.

Thanks.

Er...I'm assuming that you've have actually written the TimerProc code, and that it is bug free...

Yes, the code works fine.

The program is running fine at the moment.
I am just worried that I have had a few Excel exception errors, and just wondered whether it might be the fact that I am using a Windows API function that could have caused them.
I had no problems when using an VBA timer.
