SQL query time out

[qfchen]

Hi,

I had one problem when query in VB.net. It fails at first time after SQL server restart, the fail message is "timeout expired". The same query success in second time onward, How can I set timeout in VB dataSet property? I use DataSet to communicate with database. Below is the query statement I used in FillBy() function.

cnt = Me.EM_AWARE_20kV2TableAdapter.FillByTOP_EndDT(Me.DataSet_ESD2.EM_AWARE_20kV, samples, toF)

SQL statement:
SELECT TOP (300) CdmFilter, DateTime, DateTimeStamp, Distance, EsdCntAll, EsdCntLast, EsdLimAbs, EsdLimLin, EsdLimLog, EsdMaxAbs, EsdMaxLin, EsdMaxLog, EventNumber, IP, SvCurrent, SvMax, SvRange FROM EM_AWARE_20kV ORDER BY DateTimeStamp DESC
