Hi

i have a serious problem while i was working in Excel.I want to fetch
columns from an excel worksheet and i need to compare it with an sql
querry fields,so i tried to open an excle worksheet first..


Unfortunately my code was throwing error like


CLSID\{00020819-0000-0000-C000-000000000046} IS NOT VALID OR NOT
REGISTERED.
But the same exe is working fine in other Pc's except mine.Then i
overcome the error with the code


Dim oldCI As System.Globalization.CultureInfo =
System.Threading.Thread.CurrentThread.CurrentCultu re
System.Threading.Thread.CurrentThread.CurrentCultu re = New
System.Globalization.CultureInfo("en-US")


after that excel sheet was opening but i cant read the rows or columns
in it
error throws like "Old format or Invalid Type Library" in the
particular statement wherever i used worksheet.methodname


Here i put the entire code
