I have a program in VB.NET 2005. At some point I have to open an Access2003-Application for getting data in it. I do that by pretending my program is a human user and let it do all the work in Access as a human user would do. Filling Fields, pressing buttons etc. I use the Primary Interop Assemblies for that. So far so good. That code is in use for over half a year now. In the last week I got Office 2007 installed on my machine. Of course I tested the installed version of my program if everthing still works. Every test was succesfull. But if I do the same tests in Visual Studio it always crashes.
All I get is this Errormessage: {"Das COM-Objekt des Typs "Microsoft.Office.Interop.Access.FormClass" kann nicht in den Schnittstellentyp "Microsoft.Office.Interop.Access._Form3" umgewandelt werden. Dieser Vorgang konnte nicht durchgefhrt werden, da der QueryInterface-Aufruf an die COM-Komponente fr die Schnittstelle mit der IID "{66B22FB4-F70E-4F03-A00A-F76E9ADBBF10}" aufgrund des folgenden Fehlers nicht durchgefhrt werden konnte: Schnittstelle nicht untersttzt (Ausnahme von HRESULT: 0x80004002 (E_NOINTERFACE))."}
For all who can't read german:
"Microsoft.Office.Interop.Access.FormClass" can't be converted in to "Microsoft.Office.Interop.Access._Form3" ... Interface is not supported.
Code I use:
Dim access As Microsoft.Office.Interop.Access.Application = Nothing
.
.
.
access = New Microsoft.Office.Interop.Access.Application()
[CODE]...
The Error occurs when I try to access any property of "access.Forms("frmTest")"

I have written a program that access's data from sql and it seems to work fine, I have now installed sql to the live server and restored a copy of the data in to the new server. I have altered the connection string in the program to point to the new server yet when I compile and run it it still wants to look at the old server

I wish to create a stored procedure with multiple select statements. In addition, I then want to access each of the statements on the page load event. The purpose of the statements is to create multiple 'counts', and a number of labels on the page will each contain an individual returned count. At the moment I have created a basic stored procedure with two select statements:
CREATE PROCEDURE [dbo].[Finance_CustomerCount]
AS SELECT COUNT(Quote_ID) AS Count1 FROM dbo.generatedquotes WHERE (status = 2)
AND (Contract_End_Date >= GETDATE()) OR (status = 4) OR (status = 7) OR (status = 1)
SELECT COUNT(invoice_id) AS Count2 FROM dbo.invoices GROUP BY invoice_open HAVING (invoice_open = 'Y')
RETURN
I can then access the result of the first select statement by using this code:
Dim newconn As String = Session("ConnectionString")
Dim connection As New Data.SqlClient.SqlConnection(newconn)
Dim MyCommand As Data.SqlClient.SqlCommand = New Data.SqlClient.SqlCommand("Finance_CustomerCount", Connection)
[Code] ....
So what I basically need to know is, how do I access the second select statement result set for another label.

I've got a program where the insert/update SQL was created with the values coded directly into the SQL string. I've changed this to use the Command's Parameters.AddWithValue method and all worked well. I'm now in the process of separating the data access code out into it's own class. I've got the Select code working using a DataSet in the form that I pass ByRef to my data class so it can populate or refresh it. My sticking point is in how to pass the parameters for the Insert/Update commands to the class since from the form I no longer have access to a Command object. Do I need to make the Command object in the data access class available to the form?

I'm trying to add a computed column to a datatable that references another column in the datatable. Sometimes the computed column has a mathematical operation applied to it, but in this case I'm just referencing the original column. The code looks like the following:
ReportData.Columns.Add("1_1_US", _
GetType(Single), _
"1_1")
The code isn't actually hard coded as shown above - there are functions that return the values for the first and third parameters - but I checked those and they are returning the expected values and not generating any errors themselves.
The error is thrown when the .Add method is called, and the error states "Syntax error: Missing operand after '_1' operator." It seems to me that it doesn't like the column name, which I suppose I could change and just workaround it at the presentation level. Still, I'm curious. Is this a bug in the .net framework or something? It doesn't mind "1_1" as a column name in the datatable, so why is it having a problem with it in the expression statement?

I have created a very basic web service in vb.net using vs 2008. When I run the service within visual studio debugger, the service runs fine and gives me the expected results. When I deploy the service to the server and invoke it from a client, it always throws a NullReferenceException error when trying to access the data. More specifically when I call the DbConnection open() method within a dbhelper executeScalar method.
I'm using a custom dbhelper class I found on the web here: [URL] The only thing I've changed is the _factory at the top points to Providers.Odbc (since I'm using a ODBC connection). Like I said previously, the service (and the dbhelper class) work as expected within VS- it's only once I deploy it that it seems to bomb out. I've even tried hard coding the connection string in case it was having problems getting that but no difference there.

We are thinking about changing our current database system, MS Access 2007 front end and MS SQL Server 2005 backend to using a higher level language such as Visual Basic .Net. I wonder if this is the BEST solution for data management? Currently, among others, we have two big database programs that handle more than two hundred users and it's crashed often. That's the reason we think about changing to something that can handle these database programs effectively preferably using MS technology such as .Net.
