The error I am encountering occurs at the second con.Open() when I try to connect to a .mdb database file which I created in access, the function correctly tells me I have a password, but then once I enter my password I get the error defined in the title, and I have no idea why.

Exception Text : Can-not find installable ISAM.
I get this exception "could not find installable isam" when trying to read from an excel file in vb. I tried google and the most I get refers to a problem with my connection but I don't know how to fix that. Here is my connection string
Dim MyConnection As System.Data.OleDb.OleDbConnection
MyConnection = New System.Data.OleDb.OleDbConnection _
("Provider=Microsoft.Jet.Oledb.4.0; Data Source='" & Application.StartupPath & "kk.xls'; Extended Properties=Excel 9.0;")
I need to open and read a Dbase file in my ASP.NET application. When I try to open the connection, I am getting the exception "Could not find installable ISAM." I have tried the solutions in the top answer in this question, but they did not work for me.The filepath of the data file is C:devDATA.DBF. Here is the code I am using to try to open the connection:
Dim connectionString = "Provider=Microsoft.Jet.OLEDB.4.0;DataSource=C:devDATA.DBF;Extended Properties=dBASE IV;"
Dim connection As OleDbConnection = New OleDbConnection(connectionString)

I'm using vb.net 2003 and I want to read excel file 2003 using OleDb Connection. But I have a problem when I'm putting the IMEX=1 property on the connection String. But when I have to romove this IMEX property, the system run without an error. Here is my connection string
xlsCon = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & pathName & " ; Extended Properties=Excel 8.0;IMEX=1")
I need to put IMEX property so that it tells the driver to always read intermixed (string, integer, date) data type on each cell.
Here is the error I've encountered.

Im new to visual basic.. I would like to ask on how to fixed the problem "Could not find installable ISAM.". I used Visual Basic as programming language. I used MS access as the database. My program is to fetch data from access. This would be my code.

Module Main

I keep getting a "Cannot find installable ISAM" error in my catch. And I've set up my connection string the same way that is in my signature "Let the user select the connection string." Here is the connection string being used(I did MsgBox(con.connectionstring)
Provider=Microsoft.Jet.OLEDB.4.0;Data Source =C:Documents and SettingsPC #6My DocumentsVisual Studio 2010Projectsfajsdl;kfajsdl;klogin.mdb;Persist Security Info=False
Even if I hardcode the connection string, rather than using Dim con as New OledbConnection(My.Settings.login). I still get the ISAM error.
I'm trying to parse a user-submitted csv file in ASP.NET with VB. Here is my function:

I have a program runs with access database. It runs ok on WINXP. However, when I run it on Vista, it shows this exception: system.InvalidOperationException: The 'Microsoft.Jet.OLEDB.4.0' provider is not registered on the local machine.
I searched, it seems the exception has some relations with 64bit OS, but my vista is 32bit home version.
I want to make some exception catching code a little cleaner, if possible.I currently have the below:
Catch ex As System.Exception
If ex.Message.Contains("opened exclusively by another user") And errCnt < 30 Then
sender.ReportProgress(0, "Waiting for database to become available")

To query an excel sheet via SQL, I used to use either:
Dim excelConnectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + strPath + ";Extended Properties=""Excel 8.0;IMEX=1;HDR=YES;"""
or
Dim excelConnectionString As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source= " + strPath + ";Extended Properties=""Excel 12.0;IMEX=1;HDR=YES;"""
Now this worked fine until I installed Office 2010.
Now I get a
Microsoft.Ace.OLEDB.12.0 provider is not registered on this machine
exception.
How can I find out the correct connection string/provider?

The idea is to detect if the cell of the first datagrid column is null and display the message. However, the code is not detecting the cell as null and the table adapter is throwing the OleDb exception.
I have been programming vba for some time and am now starting VB.NET. I need to connect to an existing access db file (access 2003). I downloaded VS2010 and found an example on the net. Here is most of the code:

Dim cn As OleDbConnection
Dim cmd As OleDbCommand

I am getting this error message:

I have tried to add a reference to System.Data.OleDb but it doesn't appear in the add reference box. System.Data.OleDb is checked in the Imported namespaces window. I have tried changing the .NET Framework but, no help.
Just wondering if i might hit a snag in my program. Ive got 10+ users using the same files, via a Oledb to put info into an excel spreadsheet. If 2 or more people save there file at the same time will the program go into read only on one person. Normally one 3 will use the file at one time. I know Sql itself would be better to use. best way i can describe it, normally using excel if you manage to open the same file twice one opens as normal but the other opens as a Read only file, will the same thing happen if im using Oledb connections?

I have my .net app running on my home machine, and at one point it threw an exception.Problem is, Windows doesn't tell me what the exception is, just says that it stopped responding and closed it.I want to find the exception and stack trace so I can debug it, since I can't to reproduce the problem inside visual studio.The machine is running Windows 7 x64. I found in the event viewer some minor information:
Problem signature:
P1: server info.exe
P2: 1.4.0.0
[code].....
So based on that I can see there was a null reference. I remember way back when I was on XP, when the application crashed it would show the whole exception stack. Can I find that information somewhere?
I am currently working on an existing Windows Forms application (VB.net), and am busy reworking the exception handling mechanism.Currently, a lot of methods in the code are just surrounded with try/catch block that catches a generic exception and then calls a utility method that just shows the user a messagebox informing him of the error, and then logging it.So in a lot of cases no corrective action is taken and the exception is just logged. I know this probably isn't the best way but that's they way we're gonna have to do it for the near future.Anyway, I wanted to do this in a more generic way, so I hooked up Application.ThreadException and AppDomain.UnhandledException.
This seems to work well, except for one inconvenience. Whenever an error gets thrown from the .net runtime itself, or a 3rd party control, the stacktrace begins there where the exception is thrown in the framework-methods or 3rd party methods (obviously!)But it would be handier if I had an easy way of finding out exactly where these exceptions cross the boundary into my code. I would like an easy way of determining (in Application.ThreadException) where in my own code an exception originated. am aware this information is contained in the Exception.StackTrace property, but I would like an easy way to get to this specific information seeing as the stacktrace property is one huge string.
