Excel Formatting Issue

[Ashwini.Ghonge]

Hi,

I have embeded Excel in IE and i am performing operations like painting,
applying format and others on embeded excel using a dll. When my painting and
other activities (like formatting) are in progress and i switch to other
Office application (like Microsoft Word) and start typing, calls like
tempRange->PutNumberFormat(....); fails...
(there are other Formatting calls that fails along with this)
According to Excel behaviour, formatting calls fails when you are in Edit
Mode in same Excel application.
But when i am switching to other Office Application this calls should not
fail.
Further, sometimes this call even fails when i am typing in notepad.

Can any one tell me the reason why this calls are failing when i am typing
on some other application.

Thanks
Ashwini
