MS Access DB And VS C# 2005?
Jun 4, 2009
I have been programming in C# for some time, I would like to use (link?, connect?) a C# Windows Application to a MS Access Database (the database already exist, the C# winapp would be the GUI of this DB).
I have browsed from the internet and I have found plenty of examples, however they are different from one to another, some are from older .NET. For visual studio 2005 (the one that I use) it seems that there are two ways:
From: Menu -> Data -> Add New Data Source From: Menu -> Tools -> Connect to Database I have seen that it is also necessary to add in reference the System.Data and also add it to the program as a namespace System.Data.OleDb, and then also add some code like this in the "main form" constructor:

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 two Access database, say database One.mdb and Two.mdb. I want to use VB2005 to export tblCustomer from One.mdb to Two.mdb, and replace the existing tblCustomer in Two.mdb, during run time. I basically want to simulate the export function that is available in MS Access (which can export one table from one Access database to another) with VB2005 during run time. I can think of a way by querying the table to a dataset and then delete everything on the other database before filling the table in that database with the dataset. However, there should be something simpler and faster than that, shouldn't it? Any idea?

Namespace A and B are in different directories but are a part of the same project and solution. I try using the imports statement and referencing the class itself directly but it doesn't find it. Does anyone know what's wrong?

How do i allow the HttpListener in vb2005.net to allow outside access?
For testing purposes i have set it up to use the same ports as my webserver uses so there are no firewall issues.
the prefixes are set up to take the localhost on port 80 the realm is unset AuthenticationSchemes = Net.AuthenticationSchemes.Anonymous
it works just fine locally on the machine, but cant be reached by web browser on any other machine on my network

I am trying to access a list box using tab or an access key but to no avail. I set a label control and assigned an access key and also set the labels tab order to be one less than the list box but still have to use the mouse in order to get the list box. I also want to be able to limit the keypresses of an inputbox but I'm not sure how to add that. I can do it with a text box but I'm not sure if I should be selecting an object or not for the input box.This app is supposed to calculate total and average scores based on the number of judges selected in the list box (2-8)

I want to connect to a Access Database I've tried to do it though Data Binding and that doesn't seem to be working so I'm going to have to do this through Code... every book I have tells you how to do it with SQL Server but can't find a example for Access that doesn't involve just using the databinding tool. Writing the queries isn't a issue it's just connecting to the database and then putting that data into a couple of text boxes. Lets say the database is called TestData and the table is ClientInfo and we want to put Date, First, Last into txtBox 1, 2 and 3 respectively when the form loads.

I'm new to using databases within VB, so bear with me. I've created a couple of extremely simple tables in Access, and I've successfully connected to them in VB. My questions are:1. Is it possible to import the tables' field properties with the table, such as the captions for the columns or the number formats. Those details seemed to have disappeared during the import. Or do I need to set all these properties within VB after the

I'm building an aplication with an MS Access database behind the scene. In many of my forms I'm gonna use DataGridViews to show data from the database, not an entire table but data based on manually built queries. So, I have few questions without answers, by now. Solutions or 1. I haven't decided how will I bring the database into the project: from the menu -> Add New Data Source, or within the code, at runtime. I still don't know which one's best or why.2. How exactly can I execute any SQL query (SELECT, INSERT, UPDATE, DELETE etc) on my Access database from my aplication?

I have an Access data base back end that contains only the tables that was created in the year 2005 (by someone no longer here so cannot answer much about past and I am not very familiar with Access). When I use SSMA 2005 for Access v4.0 to migrate to SQL 2005 a table with images (defined as OLE Object) the ones that appear in the Access table as bitmap will work fine, there are ones that appear in the Access table as "Microsoft Photo Editor 3.0 Photo" or "Picture" that will not. I set up a data source and used tableadapters in a VB Windows Form and used data binding by dragging the column from the data table and dropping it on a predefined picture box on the form (this basic method works fine for all the other columns in the table). I am using Visual Studio 2008.
The Access database is over 130 megs and we are migrating it to make it available across a network to multiple and sometimes distant sites. [Code] I have used all the extensions defined in Photo Editor and this .obd is just another one I have tried to see if that makes any difference. I tried moving the array to a variable defined as an Image and then moving that to the picture box and that failed too. [Code]

We are using VB 2005(Visual Basic.net) with SQL server as database and MS Access for the Reports. Right now we are passing the footer label from our VB app to MS Access for a selected report. If the user closes that report(not closing access) and opens another report the footer label is not being displayed. Is there any way I could send the footer label to all the reports in Access as soon as I open the database.Right now in below code we are sending the footer label just for the report selected. Is there a way to send the footer label to all the reports that are existing in the Access database.
Here is the code we are using right now.
Public Sub printReports(ByRef trn As ITTransaction, ByVal blnPreview As Boolean)

I want to know if I can directly read or write values in the current process in a Visual Basic 2005 Windows application. Like *(DWORD*)(0x123456) = 1; in C++ will write the value 1 at the address 0x123456. So anyway to do the same in VB using only built in functions and not using ReadProcessMemory and WriteProcessMemory?

OK, before I throw my laptop out the window... I need to insert data into my Access Database from my VB.Net2005 application. I have written and re-written this code, trying everything I can find from the web and I've had no luck. I'm getting a {"Data type mismatch in criteria expression."} error on the ExecuteNonQuery line - I'm fairly certain that it's the DateTimePickers, as I rem them out and the code works fine. However, I've tried everything - changed the column in my database to Text, changed the .Value to .Text, .Value.ToLongDateString, and every time I'm getting the same error. One of the things I read on line was that I need to use parameters in order to pass the DateTime - I need to pass the Date and Time (date format is not important, but I require the hh:mm:ss format for the time). The fields currently default to the current date/time which is perfect, but I read that depending on how you pass the data, you may run into problems if the user does not pick the drop box (leaving it as the default).
