Question

I add C# group too in this, because this is not VB problem but ExecuteNonQuery gives timeout. how to increase the time-out?

Exact errormessage: ERROR [HYT00] [Microsoft][ODBC SQL Server Driver]Timeout expired

we do have cms system and in that CMS I have created a IFRAME which calls this ASPX +VB code, which is in different physicall folder and it has managed Pipeline Classic.

When I run this in Old application it works fine. But I copied the pages to the news server and created new application pool/website Call OldASPPAGES I get ODBC timeout on ‘ExecuteNonQuery()’ function below.

Sometimes I works but 9 of the 10 cases I gettimeout. I checked the records and there are 247 records. But below you see there are 2 sql statements composed per Each loop. (update and insert)… 2 x 247 records = approx. 500 records.

But since the sql statement is concantenated so 1 call of ExecuteNonQuery, executue does do 500 SQL Statements….

I know this is GARBAGE, unacceptable…. But I inherited so for the moment I can’t rewrite that.

To the point:

Below are the original statemenst: I have just added : conn.ConnectionTimeout = 240
As you can see I’ve added 240 seconds, but I still get timeouts after approx. 30 secs… so this is not the right place….

question:
– Why does this statement work in old ASP environment (without problem) and not in this environement in an IFRAME….

• I set timeout =240 but I still get timeout after 30 secs. Where do you set the timeout more?

Can someone advice?

thanks

Have you tried the CommandTimeout property on the Command class yet ?

However, that’s only symptom-fixing. Can’t you tweak your query to make it more performant ?
