SqlCommand.CommandTimeout not working

[cmhavoc]

Can someone please look at my code and tell me what I might be doing
wrong? I'm getting the following error:

Exception Details: System.NullReferenceException: Object reference
not set to an instance of an object.

for the line with "cmdCat.CommandTimeout = 300"

How can I set the commandTimeout?


See my code below

------------------------------------------------

sub page_load(sender as Object, e as EventArgs)



Dim sqlcon As New
System.Data.SqlClient.SqlConnection(System.Configuration.ConfigurationSettings.AppSettings("CONNECTION_STRING"))
Dim cmdCat As System.Data.SqlClient.SqlCommand
cmdCat.CommandTimeout = 300
Dim daCat As System.Data.SqlClient.SqlDataAdapter
Dim dsCat1 As New System.Data.DataSet

Dim strCat as String = "SELECT GOES HERE"

daCat = New System.Data.SqlClient.SqlDataAdapter(strCat, sqlcon)
sqlcon.Open()
daCat.Fill(dsCat1)
sqlcon.Close()

rptEmails.DataSource = dsCat1
rptEmails.DataBind()

Page.DataBind()
end sub

Dim cmdCat As System.Data.SqlClient.SqlCommand

At this stage you haven't set cmdCat to a New
System.Data.SqlClient.SqlCommand(cmdText)
So there is no Object to reference.

Dim sqlcon As New
System.Data.SqlClient.SqlConnection(System.Configuration.ConfigurationSettings.AppSettings("CONNECTION_STRING"))
Dim cmdCat As System.Data.SqlClient.SqlCommand
cmdCat.CommandTimeout = 300

At this point cmdCat is a variable of type SqlCommand that is set to
Nothing. You need to allocate an object:

Dim cmdCat = New System.Data.SqlClient.SqlCommand

Thank you ... that fixed that error but now I'm back to getting a
timeout error. The weird thing is that it times out after only 30
seconds even though I have this and the IIS and the web.config set to
300 seconds. Any thoughts? Below is the error.

Thank you ... that fixed that error. However, now I'm back to my
original timeout issue. It times out after only 30 seconds, even
though I have this timeout set to 300 seconds and likewise for my
web.config and IIS. Any thoughts?
