My Source code is
Imports System.Data.Odbc
Public
Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
[Code] .....
The table1 contains two parameters name and emplyoyee no. I am using Odbc driver. The connection is ok. But I am getting the error
An Odbc Exception occurred : {0}ERROR [07002] [Microsoft][ODBC Microsoft Access Driver] Too few parameters. Expected 1.
Is there any way to pass multiple values (a list of values) to a query via ODBC Parameters in VB.Net?
For instance, is there a way to create a query along the lines of:
-- vb.net has something like Dim itemNumbers As New List(Of Integer)(SomeCount)
SELECT Cost, Description
FROM MyItemList
WHERE ItemNum IN (<my list of item numbers>)
I'm connecting succesfully to an Oracle 10g DB with an the Microsoft ODBC for Oracle driver.Regular queries without parameters work fine, but parameterized queries act as if the parameters aren't getting passed in.ex.
--this works fine
Select * from tbl1 where column1 = 'test'
--this doesn't
select * from tbl1 where column1 = ?
--odbc string parameter 'test'
Here's what my connection string looks like:
"Driver={Microsoft ODBC for Oracle}; " & _
"CONNECTSTRING=(DESCRIPTION=" & _
"(ADDRESS=(PROTOCOL=TCP)" & _
[code]....
I use codes below to inserts values to database by executing stored procedure.
Dim connstring As String = "dsn=test"
Dim oConn As Odbc.OdbcConnection = New Odbc.OdbcConnection(connstring)
Dim com As New Odbc.OdbcCommand("{? = call sp_test1(?,?,?,?)}", oConn)

I am getting the following ODBC exception when I moved my development platform from Windows XP X86 to Windows 7 X64: ERROR [IM014] [Microsoft][ODBC Driver Manager] The specified DSN contains an architecture mismatch between the Driver and Application What I'm sure it means is that the server it is connecting to is 32 bit, and the computer I'm running on is 64 bit and the ODBC driver in use is 64 bit.
The application I am writing is set to run in 32 bit mode because some of the third-party software that we employ is not 64 bit compatible. I tried downloading a 32 bit driver and changing the DSN but it did not fix my issue. I still get the exception. If anyone has any links for 32 bit SQL drivers, or how I could fix this by changing the project around, I'm all ears.
I have a small vb.net application that fires a crystal report through crystal viewer.
The report uses an ODBC connection provided by 32-bit software accounts package, which is installed in the ODBC 32-bit This all works fine on 32-bit XP and 32-bit Win7 with no problems, When run on a win7 64-bit machine the application launches ok, but when it comes to running the report, it prompts for a database logon box for the odbc connection.
When the report is run seperate on its own, on the exact same pc through crystal reports desginer it runs fine, Its almost like the application is not picking the 32-bit ODBC set up is it the case that the connection needs to be coded rather than using the report connection,
i am new to vb .net i just want to ask why is it i don't see the odbc data adapter in the toolbox pane? i just have (under data) pointer, dataset, datagridview, bindingsource, and binding navigator.
View 3 RepliesIt 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 should be able to get result back as long as there's a match in the parameters. If I use Function Contains (q.FirstName & " " & q.LastName).Contains(employeeName), I will not get any result back if employeeName is "John Clark" Function Contains looks only for next words from left to right. It doesn't match a single word at a time. So that's why I used this in the Linq to SQL:

Basically Commands has Parameters and parameters has functions like Add, AddWithValue, and etc. In all tutorials i've seen, i usually noticed that they are using Add instead of AddWithValue.

since it saves my coding time. So which is better to use? Which is safe to use? Does it improves performance?
is there a way to get the GET parameters and POST parameters in just one function or Collection in ASP.NET? Like using $_REQUEST in PHP? I'm using VB.NET.
View 3 RepliesI 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...

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)

i have about 20 possible exception messages that i want thrown when an error occurs.i need somthng like this when catching the exception
Try
' do domthing
Catch ex As CustomInvalidArgumentException

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]
