"Bad Variable Type", Excel, W2K

[Alfredo Magallón Arbizu]

Hi,

I have an ASP.NET app that works perfectly in Windows Server 2003, but fails
in Windows 2000.

It fails when trying to read the data in an Excel Workbook (range.value)...
The error is:

COMException (0x80020008): Bad Variable Type

The app works in Windows Server 2003 !!!

Why it fails in Windows 2000... Any idea???

Thanks,
Alfredo

Hi Alfredo,

Generally speaking, the error happens when you have different versions of
Excel. If you referenced Excel 10.0 (Office XP) type library in windows
2003 server and then use the same program in a machine with Excel 2000, the
error happens. So please make sure that the version of Excel is the same.
If not, please add reference to the right type library in your program.

Hope this helps.

Hello Alfredo,

I noticed that you also post this issue to another newsgroup
"microsoft.public.office.developer.vba". One of my colleagues replied there
and I paste it here for your reference. Please let us know if the following
information helps you resolve the problem.

"Alfredo,

I found a case that describes similar symptoms to those you are seeing.
Please check the following:

1) Excel is installed on the Windows 2000 machines. Excel.exe is an
out-of-process server and has to be installed on the machines on which you
wish to automatic. The Excel version must match that refernced in your
program or you will receive interface mismatch errors.
2) Check that the expression you are building to access the range matches
the data type expected. In a previous case

xlSheet.Cells(i + 4, 1).Value = "Test Value" produced the same error
because i was declared as long and is expected to be integer.

If this information doesn't fix your problem, please feel free to post the
following information:

1) A snipet of the failing code
2) OS and Excel versions in the various environments
3) Whetther you are using VB or C#

Thanks,

Jim

I changed range access variables from long to integer, and it works now !!!

Anyway, I consider this a very limiting issue and a bug to be corrected, as
it is if I use Windows Server 2003.

Many thanks for your help!!!
