(using VB2008) I am trying to automate Access from VB.Net. To do this, I added two libraries to my project, Microsoft.Office Interop.Access v12.0.0.0, and dao v10.0.4504.0. This seems to give me all the necessary commands, yet when I tried to open up an Access database via the following code:

View 1 RepliesA. A Visual Basic program is developed to read a text file to Access 2003 database using the Data Access Objects (DAO). The following is the DAO command:
Set db = DAO.DBEngine(0).OpenDatabase("C:TempMyAccess2003.mdb")
B. The office Access 2003 database (*.mdb) is going to be upgraded to Access 2007 database (*.accdb).
C. The Visual Basic program is revised to read the same text file to Access 2007 database using the same Data Access Objects (DAO), The following is the DAO command:
Set db = DAO.DBEngine(0).OpenDatabase("C:TempMyAccess2007.accdb")
D. The following error message occurs when the revised Visual Basic program is executed:
"Run-time error '3343': Unrecognized database format"
I had previously used VB6; I am now using VS2008; What is the best manner to now open the database using the VB code? The code works with the Access 2003 database.

View 1 RepliesI have an app with a password protected MS access database connected to it. lets say the password is "123".
when I run my app i get an error saying that the password is incorrect even thought its not.i have been readig around but am strugling to find a solution.
this is the line that causes the error:
Me.Table1TableAdapter.Fill(Me.PassSafeMianDataSet.Table1)
I can't open an Access database on a mapped drive. However it works if I use the UNC path. how I can get this to work? See the code below for an example of what works and what doesn't...
Code:
mConnString = "provider=Microsoft.Jet.OLEDB.4.0;Data Source=\tiger-2000dvb_mt7MTrackBE.mdb" ' This works
mConnString = "provider=Microsoft.Jet.OLEDB.4.0;Data Source=T:vb_mt7MTrackBE.mdb" ' this does not work
Dim objConn As New OleDbConnection(mConnString)
[code].....
The error message I receive is...'T:vb_mt7MTrackBE.mdb' is not a valid path. Make sure that the path name is spelled correctly and that you are connected to the server on which the file resides.I've done the obvious and verified that t:vb_mt7MtrackBE.mdb is a valid path.
I've been working on an application for awhile that, basically, allows the viewing and printing of a maintenance database. It allows the user to view basic information for the object and then view the maintenance history. My approach for the maintenance history is simply to have unique tables per object since a history has to be kept for each, however, I'm running into a problem in the application that allows the user to view the general information from one DB and the Maintenance history from the other DB.
Say you have Object ID BG1. I can enter the object ID into a search field, pull the data from the general DB and display the data, but I also need it to pull the information from the maintenance history and display. If maintenance history for this object is not found, then create a new table within the DB, fill the columns with the required fields and allow for the user to edit the history.

View 2 RepliesI have an access 2007 database that I have been developing a front end for in vb.NET for the past 3-4 weeks using vs2008 in a Windows 7 enviroment. Yesterday I started getting an error of "Your network access was interrupted. To continue close the database and then open it again." This happens in the Form Load on the line:
gotData = Me.LeaguesTableAdapter.Fill(Me.LeaguesSeasonsPlayersDataSet.Leagues)
I can go into access 2007 and view all the data fine and in vs2008 I can view the server explorer and browse the tables. However, under data sources if I try and preview the data, I get the same error message as before. What confuses me the most is that the database is not stored on a server is just stored in My Documents. It was origionally stored on my desktop pc but has been copied to the My Documents on my laptop. But as I mentioned previously it has been working fine and has just all of a sudden started throwing this exception by my Try Catch routine. FYI I have tried creating a new DB and importing the tables from the old DB but this hasn't solved the problem either.
this is my code for adding users in my database but it has an error on the INSERT INTO statement.here is the error: Microsoft office access database engine: syntax error in INSERT INTO statement.

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.
