Binding source does not update when the linked table is updated in code.

Hello All,

I am currently in the process of adapting an application that previously worked only with Microsoft Access to work with SQL server or Access. Previously, all database interaction was designed based upon using the XSD file to create queries (etc).

I wasn't sure how to handle the new situation with two types of database using the visual methods (e.g. did not want two separate datasets (etc) so I created a static class that contains a function as follows:

<br />
public static DataTable SelectRows(string connectionString, string queryString)<br />

The function will connect to either type of DB based on the connection string and will run the query held in queryString returning a table of the selected records.

I create a binding source and assign it to a table called masterTable as follows:

<br />
cards_photo_accesslevelBindingSource.DataSource = masterTable;<br />

I then have a DataGridView that points to the binding source as follows:

<br />
dgNavigatorTable.DataSource = cards_photo_accesslevelBindingSource;<br />

At various times in my code, I call the SelectRows method and store the returned table over the top of the masterTable as follows:

<br />
masterTable = MyQuery.SelectRows(MyConnectionStrings.getConnectionString(),<br />
            "SELECT * FROM (Cards LEFT JOIN Photo ON Cards.Card = Photo.Id)LEFT JOIN AccLevel ON Cards.AccessLevel = AccLevel.AccessLevel WHERE Cards.FirstName LIKE '" + tbFirstName.Text + "%'");<br />

My first concern is that the binding source does not update in relation to the update of the table.

I have found that the only way to get the binding source and associated DataGridView to update after my masterTable has changed is to re-assign it as follows:

<br />
// This seems necessary to update the navigator linked to the binding source<br />
cards_photo_accesslevelBindingSource.DataSource = masterTable;<br />

Even using this naive technique, I also need at this point the PositionChanged event to fire on the binding source as it used to when I would call a Fill method on the datasource before I replaced this method with my SelectRows method.

I haven't done much C# for a while and previously have always used an XSD file for my database connection and queries and therefore I assume that I am using the binding source and DataTable in an illegal and naive way? I will keep searching the web for an answer and apologise in advance for my lack of understanding.

Regards,

Chris

Hi All,

I have a very strange problem with xp_cmdshell. Here is a Stored Procedure that is meant to execute a VB script file.When i run the VB Script independently it works fine.

But when i execute the stored procedure that is pointing to this VB script file it runs with No error But Doesnt do the work.

Stored Procedure

USE [Database]
GO
/****** Object: StoredProcedure [dbo].[sp_SendSMS] Script Date: 06/27/2010 10:14:13 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

CREATE PROCEDURE [dbo].[sp_SendSMS]
-- Add the parameters for the stored procedure here
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;

DECLARE @Numbers NVARCHAR(200)
DECLARE @Body NVARCHAR(160)
DECLARE @Command NVARCHAR(500)

-- Insert statements for procedure here
SET @Numbers = '00442345672'
SET @Body = CAST(GETDATE() AS NVARCHAR(20)) + ' Test Message'

-- TODO: Get Revenue Statistics and append them to @Command
SET @Command = 'd:\test\SendSMS.vbs /Numbers:' + @Numbers + ' /Body: "' + @Body + '"'

EXEC xp_cmdshell @Command
END

The VB script file is under test folder on D drive which has Read write permission set on the folder.

Set WshShell = WScript.CreateObject("WScript.Shell")
sNumbers= WScript.Arguments.Named.Item("numbers")
sBody= WScript.Arguments.Named.Item("body")
URL = "http://sampleweb.com/samplepage.aspx?IFVERSION=210000&MESSAGETYPE=10&OADC=00447956053317&MESSAGEID=3333&RECEIVETIME=20070320151916&BODY=This%20is%20my%204th%20message%20on%20the%20LIVE%20TV&MCLASS=2&HEADER=0048001&DESTADDRESS=1234&CONNECTION=MIG01l1&DCS=240&RETRYCOUNT=3&PID=0&AVSTATUS=1&GUID=9BBA5E93-390C-450C-94C3-1122E5D4858B"
WshShell.Run(URL)
Set WshShell = Nothing

When i run the VBS file Independently it works fine.However when running the stored procedure above which contains the file i dont see the file being excuted.

Could You please advice what is going Worng?

Thanks for your time.

So let me get this straight; you're using a stored proc, to execute a VBS file which makes an http request to send an SMS? Multiple points of failure doesnt even begin to describe this monster.

Anyway, in answer to your question, its almost certainly a permissions problem. When you execute the VBS file directly, its running in the context of the currently logged in user. When you run it using xp_cmdshell its running in the context of whichever user SQL Server is running as.

Thanks for your reply.Its Much appreciated.I have already checked and changed the user who loggs in as An is An administartor.

Is there any thing i have to do to force the Login name to remain as the one who had access to that particualr folder.

Many thanks for your Info.

There are so many things wrong with that response.

That is why you can run the VBS manually. your logged in user is an admin, and as an admin has rights to run the script. SQL Server runs as a service, it knows nothing about your logged in user, and has a completely different set of permissions.

This problem has exactly nothing to do with folder permissions. You can give a user permission to read a file from a folder, but they may still be denied things like "Execute processes".

If you have acccess to sys admins, ask them for help. If you dont then start reading up on the permission system in operation for the OS you're using. It varies quite substantially between older generation servers like Win2K and new generation servers like Win2K8.

Finally, nobody here will be able to help you on this problem, as none of us have access to your servers, and all servers are set up differently.

Dear All,

Please help me to JOIN 2 table from different server.

Thank you.

1. Some "more" (more than JOIN) information would help.
2. Read the guidelines at the top of this page.
3. Where is the question?

Infrastructure/Environment fail.

Now, to answer your question; execute sp_addlinkedserver[^] to link the two servers, then using the server name to fully qualify a table, write a join in the normal way.

This post assumes MS SQL Server.
