Need help finding a flaw in my code
Hi,
I need to look up the number of certains rows and if the number is greater than 0, I upload the database. Now in rare cases I know for a fact there are a number of rows in the database but IntAantalRB stays at 0. I can't reproduce this issue but this needs solving asap, I'm hoping someone can help me with this?
Kind regards,
MrFawlty

Dim blnTestAantal As Boolean
IntAantalRB = 0
Using conn As New SqlCeConnection("Data Source=\SD-MMC Card\Database.sdf;")
Mobile.DtaDocument.Connection.ConnectionString = "Data Source=\SD-MMC Card\Database.sdf;"
Try
If conn.State = ConnectionState.Closed Then
conn.Open()
End If
Mobile.DtaDocument.Fill(Mobile.adsMobile.DocumentRB)
IntAantalRB = Mobile.adsMobile.DocumentRB.Rows.Count
conn.Close()
blnTestAantal = True
Catch ex As Exception
conn.Close()
IntAantalRB = 0
End Try
End Using

I only want IntAantalRB = 0 when there are Rows.Count = 0, the problem is that in some cases I'm 100% sure Rows.Count should be > 0 but something goes wrong with retrieving this information.
I need to make 100% sure that Rows.Count is actually > 0 or = 0.
Perhaps the sdf is locked?
How can I be 100% sure I get the correct Count?

Hi OP_Zaharin,
- I don't display the result, if Rows.Count > 0 I upload the sdf in question but in 0,5% of cases this code returns intAantalRB = 0 when it should be > 0.
- IntAantalRb is a property.
- True, overkill :(

At what point in the code do you want IntAantalRB = 0? When theres an exception? Or at the end of the Try block?
Try
If conn.State = ConnectionState.Closed Then
conn.Open()
End If
Mobile.DtaDocument.Fill(Mo
IntAantalRB = Mobile.adsMobile.DocumentR
conn.Close()
blnTestAantal = True
Catch ex As Exception
Finally
conn.Close()
End Try
