My problem does not seem to be the same as in other links. I'm trying to teach myself VB 2008 and I want to connect to an Access MDB file. I follow the instructions in all the different books and websites. I start a new project, choose a new data connection, change the type to Microsoft Access and browse for the file. When I get the connection string I press "Test Connection" and it's okay. I then drag either the entire table or just a field to the form. I use Data Preview Data and can see all the rows and columns and the data, so I know the connection has been made. however, when I press F5 I get a form, but no data and it says "0 records of 0".
I accessed the code and put a MsgBox before and after the "Fill" statement. The one before pops up, but the second one (below Fill) does not. I also get "A first chance exception of type 'System.InvalidOperationException' occurred in System.Data.dll" in the Immediate Window. I have tried putting a "Try" statement around the code and in this case it will go to the second MsgBox, but still no data.
I'm following what seems to be the most basic and simple method, but I cannot get data in my form.
I would like to know how to upload .doc files to access database in VB.NET.All the codes I find are ASP.NET I don't understand how to do that in Vb.net.
I have a large text file that I want to use in my project, that data in the text file has about six items for each location. Now I had thought of importing the text file into a database using Access, but not had a lot of luck making it work. The question is is it better to load the data in the project as a text file then search for the string required or to convert it into a database. (The text file is a list of airports and related data.) Can a text file be converted to a Microsoft compact SQL database?

Friends I have Developed my Data base Project on vb6, using adodc and datagrid using ms access database file, it was working nice in vb6, I also put Search box there and used adodc1.recordsource="select * from table" sql query.
later i needed to convert it in vb.net I converted it, every thing is working fine, but one problem appears, an adodc's Recordsource query for searching records is not working, it only works if there is data in dataset (Datagrid),suppose once i pressed search button to search record and if no record found then dataset / datagrid becomes empty, now i wanted to search an other record with other name, but this time it does not work and following error appears Either BOF or EOF is True, or the current record has been deleted. Requested operation requires a current record.

I have the following code where I make an copy of my database that I use. the code executes 100% but the problem I have is I'm not able to access my database afterward.I get a "Cannot start your application. The workgroup information file is missing or opened exclusively by another user." and so if I restart the application it all works fine again.I'm certain the reason is because I can only access that database using a specific account name and password which is not account I'm logged in with.What i want to try is to default that database mdb to the point where no user is accessing it, or to reassign the the only account name that can access it to that database mdb. I've tried playing around with file security but had no luck.

I recently made a small exe program that connects to an Access database.Now it runs fine on most computers, but the one it HAS to run good on has some pretty harsh restrictions set on it's network.The problem is an OLEdb connection is refused because the file is not trusted on the Network, and I don't know how to give it the access it needs.I've tried running an install with it, and that will give it access, but only on the local computer and not on the network drives.I've tried placing the database in the network drive and accessing it with the install there, but there is a problem in that the local drives are wiped at logout.I've tried giving it trust access through Administrator Tools, but it always throws an error when I try it.
I use the following code to import a XML file into an Access database: dbname = "c:PC Auditer.accdb" xmlFile = strFileName Dim ds As New DataSet Dim streamRead As New System.IO.FileStream(strFileName, System.IO.FileMode.Open) ds.ReadXml(streamRead) streamRead.Close() [Code] ..... The import works fine, but when a next XML file is imported with less records, the database don't get updated and the 'old' records remain in the database.
