i have a macro that opens a webpage, 99.9% of the time it works, for some
reason this time the webpage did not open and i got a message that
says...Microsoft Excel is waiting for another application to complete an OLE
action.
is there any way to get around this or at least be able to save excel before
i close it?

thanks in advance

This doesn't necessarily mean that your macro won't be able to open the
webpage at some point. It's an OLE timeout. I don't know an easy way to
change the default value to something higher. In C/C++ you can use the
CoRegisterMessageFilter to avoid this message. Here's an article where this
API call is used:

Hi Fredrik,

You can do the same thing in an Excel app like so:

Declare Function CoRegisterMessageFilter Lib "OLE32.DLL" _
(ByVal lFilterIn As Long, ByRef lPreviousFilter) As Long

Private mlPreviousFilter As Long

Sub Auto_Open()

CoRegisterMessageFilter 0&, mlPreviousFilter

''' Do your stuff here.

End Sub

Sub Auto_Close()
''' Restore the message filter.
CoRegisterMessageFilter mlPreviousFilter, 0&
End Sub

I use this all the time when my business logic is in a DLL and I'm
debugging into the DLL. Otherwise Excel times out in a manner exactly like
that described by the OP if I'm debugging for more than 30 seconds or so. It
works fine, but I don't fully understand why. I've never seen any value
other than zero returned to the mlPreviousFilter variable, so I don't know
what exactly is being unregistered and reregistered.

You are missing lPreviousFilter type in you declaration:

Declare Function CoRegisterMessageFilter Lib "OLE32.DLL" _
(ByVal lFilterIn As Long, ByRef lPreviousFilter -->As Long<--) As Long
