Error As No Value Given For One Or More Required Parameters.[code]...
View 2 RepliesI wanted to know how I can solve my error.I used the "Add New Datasources" wizard to create a conection to my acces database with visual basic.net 2010. I then added two more after I created the datasources and I dragged the table navigator from the dataset from the datasouces window and I ran the system and It was bringing the information and was working great. However I then decided to add a few more columns to my table, and that is where the problem began the next time I tried to run the system it gives the error "no value given for one or more parameters"If you think it you can achieve it

The bold/underlined text is where the error is coming up.What am i doing wrong? I've got a feeling it is something really stupid as i modelled the code on an example project that a teacher gave me, so it's practically the same code except for the field names etc.
I'm getting this error, Update error: No value given for one or more required parameters, which seems to indicate a variable is not making it to Access or is empty. My procedure is meant to update a product record in the database.

No value given for one or more required parameters. I found the code in a vb.net book someone lent me. It doesnt work at the moment and I wondered if I have everything correct the bit at the top in brackets (Phone LIKE?) is that saying check if there is a row in the 'Phone' column that is the same? Because I am also selecting Phone (the column) in that line? Later I say compare to Form3.Textbox1.Text so I am not sure whether they should both be 'Phone' inthe SQL line? Is it saying that If it finds something display whatever is in the details column to display in the text box?

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

The Error occurs when I try to access any property of "access.Forms("frmTest")"

I have an MS Access 2003 database built that resides on a shared network path at the company I work for.The database works perfectly for users connected directly to the company network.However, when a user tries to open the database while connected remotely to the company network (they can still access the shared path), they receive the following error:The Microsoft Jet database engine stopped the process because you and another user are attempting to change the same data at the same time.At the time that they tried it, they were the only person accessing the database.They tried a local copy as well as a copy on the network shared drive.[code]
