Hi All,

My c# windows application is crashing when load variables operation is performed in my application. In this operation, the variables queried from compactSqlce is not getting stored in a dataview, in VISTA, but works fine in XP.

The operations throwing exceptiop are,

query.AsDataView();

or

query.copytodatatable();

the query is fetching the required values, but fails to put them to a dataview or datatable.

This issue is occuring only in VISTA

Please help!

What is the error you are seeing? Can you paste any info from the exception that is thrown? If you're not getting a dialog with infos, check the event log. Cheers.

EnumerableRowCollection<devicevariablesdataset.devicevariablelistrow> query =
from rows in mVariableList.AsEnumerable()
where rows.Monitored == true
orderby rows.VariableName
select rows;

mSelectedVariablesLock.EnterWriteLock();
try
{
mSelectedVariables = query.AsDataView();// throwing exception
}
finally
{
mSelectedVariablesLock.ExitWriteLock();
}

Hi Espen, thanks for the input. The VISTA system has .net f/w 3.5 sp1 installed.
However I found out that the method asdataview is supported in VISTA sp1 or later.
I want to know if there is a work around for VISTA with versions previous to SP1.
