Hi
Someone replied requesting some samples of failing code:
The following Try..catch statement does not always work:
Try
NNoteId = myNotes.Create(mybizUser, AddString)
NumNotesCon = NumNotesCon + 1
Catch myE As Exception
Try
If myNotes Is Nothing Then
myNotes = New
Microsoft.CRM.Platform.Proxy.CRMNotesManager
myNotes.Credentials =
System.Net.CredentialCache.DefaultCredentials
myNotes.Url = StrDir & "CRMNotesManager.srf"
End If
If RetryCreateUpdate() = True Then
NNoteId = myNotes.Create(mybizUser, AddString)
NumNotesCon = NumNotesCon + 1
etc...
end try
end try
If the original line of code fails I want to catch the error and check and
retry some connections and then try the create function again. However I get
a connection failed popup error which is possible and the reason I want to
trap any error caused by this line. I am not new to ado, I am new to .net
however I can step thru my code and see that the catch statement is not
working or in some cases it is woking however the error still pops up. This
seems to be mostly a problem on win 2003.
Isdbnull sample
isdbnull(myRS.Fields(5).Value)=True then ......
myRS is an ado recordset connecting to an ODBC database and a single table.
The statement simply does not always return the correct true/false value
based on the field value, regardless of the OS.
