MsOf07 [RESOLVED] Error in reading excel 07 from vb.net 2005

Hi all,
i have the following error.

Code:

'Sheet1$' is not a valid name. Make sure that it does not include invalid characters or punctuation and that it is not too long.

At first, I can read the same excel file with the same sheet name without this error.
but now i change the development PC and it hit this error.

I'm using Excel 2007 with VB.Net 2005.
Here is my connection string:

Code:

"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & strFile & ";Extended Properties=""Excel 12.0 Xml;HDR=YES"";"

And I also added the COM references for Microsoft Excel Object 12.0 in my project.

Any idea??

Help :(

Thanks.
