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;")
Dim con As New OleDb.OleDbConnection Sub connecttodatabase(ByVal fileselected As String) Dim databasepassword
[code].....
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.
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
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.

Am getting the below error at the time of running form to save data. Am checking step by step, at that time i found the error occured in the open connection line [Con.Open()]. Am Using MS Access 2007 for Database. Kindly give any solution to solve this error.

I am learning visual basic .net 2008. I am trying to connect to the access 2000 database and am recieving the following error "Could not find installable ISAM. The other issue is that I am running these applications on a Windows 7 operating system. the office package installed on my computer is 2007.
I finally got the code I needed for inserting data to an Access database and it's working fine. Now I'm applying the same code to a new Button object and I'm getting that ISAM error thing.
Here's the code I'm using and the error I'm getting: Dim saveConn As New OleDbConnection _ ("Provider=Microsoft.Jet.oledb.4.0;Datasource=c:usersEuclides MediciDocumentsVisual Studio 2005ProjectsSistema de Inventario 2007Sistema de Inventario 2007Sistema_de_Inventario.mdb") Dim sql As String = String.Empty Dim clear As String = "" [Code] .....

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.
Imports System.Data.OleDb Module Main Dim mDataPath As String
I am gettig "could not find installable isam" while connecting to access 2007 databse the code that i wrote is: Public Sub MyConnection()constr = "Provider=Microsoft.ACE.OLEDB.12.0;Data
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 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.
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:
Dim Cmd As OleDbCommand Dim SQL As String Dim objCmd As New OleDbCommand Dim Con = New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;""Data Source= C:\Users\STRIDEO1\Desktop\HIS1.accdb;User ID=Admin;Password=;")
I'm scanning using WIA. What is happening is there is a temp file created under "C:Documents and SettingsuserLocal SettingsTemp". For some reason, the WIA service is deleting the temp file before I can transfer the image. The exact error is: "The system cannot find the file specified. (Exception from HRESULT: 0x80070002)". Is this a bug in WIA? The error occurs on the last line...

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...

I'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"
When 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)
