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 _

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:

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
Dim mDataPath As String

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)

Even if I hardcode the connection string, rather than using Dim con as New OledbConnection(My.Settings.login). I still get the ISAM error.
It is possible to catch an exception and throw a new exception which wraps the first exception as an inner exception: [URL] Also, if I call a function and it throws a certain error, but I catch it, will the calling code's catch handler execute? If so, and it is of a higher exception type, is this not wrapping the exception? eg I can throw exception ex of type IndexOutOfRange, log it but rethrow, catch a higher up exception and do something, or I can throw a new exception and wrap an inner exception like:

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

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?

I have a large project where we have 2-3 dll projects that are converted from VB6 to VB.NET. We have fixed all the issues that caused compilation errors, and most of obvious issues in running, so now we have basically a program up and running. The exe is created from scratch in VB.NET, using a lot of functionality from the converted dll's (including GUI forms). What I wonder is when I run the program in debug mode, I get a bunch of warnings in the "Immediate Window" saying:
A first chance exception of type 'System.Exception' occurred in Microsoft.VisualBasic.dll
...and some of other type (but most of them in Microsoft.VisualBasic.dll).I was wondering if this is common in projects converted from VB6, or if it is caused by bad design in our code...

View 4 RepliesI'm trying to catch a user defined permission exception - i.e. a user does something their level of system access won't allow, permission exception is thrown. My problem is, the exception is caught and then rethrown as a genertic System.Exception.Is there any way I can deduce the original exception type, without resorting to string comparisons, like if ex.ToString.Contains("Permission denied"
View 2 RepliesWhen catching an exception in .net, you can have as many type-specific exception blocks as needed. But I usually try to have at least one "general" exception catch block. But is there a way to get the type of the "real" exception thrown that is caught by the generic exception handler, perhaps using reflection?For example, if I have
Catch ex As System.ServiceModel.FaultException(Of InvalidUser)
ProcessModuleLoadException(Me, ex)
Catch ex As System.ServiceModel.FaultException(Of SQLExceptions)

do i have to create a class that inherits from Exception for each type of exception?
Is there anyway to create a Custom Exception without inheriting System.Exception?
my reason is that they have a lot of methods which i do not wish my Class to have.
I have written a program which uses a SQL exception class and then use it show custom messages for the primary key violation. Also i want the primary key value that caused the violation. How can i get all the primary keys which generated the exception from the sqlexception object.[code]
