I am updating some apps because the server will be replaced very shortly.The apps were created in VS 2005 and upgraded to vs2008.For some reason. my update command does not seem to work when I changed over to the new server.All settings that I have are pointing to the new server. The table Adapter has been updated to reflect the change too.I'm able to add a record to the table - I'm using this in my code:

Does anyone know how to do it? Or can give me some Tutorials?
View 5 RepliesI have ALWAYS used the SQLDataSource to update my records in my SQL Server 2005 database, so i am not really sure how this would be done in normal code. I am using VB.NET but if you are a C# developer and want to show me some code that is more than welcome as well.
I am using ASP.NET 3.5.My user will see a page with 5 Text boxes with their contact details in. Those details I will get from a SQL Server DB and when they go and change the text in the text box and click submit, it must then save the changes.
This is very easy with the SQLDataSource but how can i code this myself?

I believe my problem is fairly simple, and not uncommon among programmers switching from VBA (Access) to the big leagues (SQL Server / VB.NET). I'm using a 30-day trial version of Visual Studio 2008 and SQL Server 2005.
Now, I've created a form with a datagridview control that pulls information from my database on the SQL Server, and I use this code to put the changes back to the database. This code works perfectly:
Private Sub frmTrendsPlanningList_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
Dim command_builder As New SqlCommandBuilder
command_builder = New SqlCommandBuilder(daTrends)

Using Office automation in Word 2007, I view the Document Information Panel, showing me properties of a document that resides in a SharePoint location. Using VS 2008, I interrogate the following in the Immediate Window:
[code]...
but I don't see a corresponding change to the screen. I do however see that, on Advanced Properties/Custom Tab that a Custom Property by the name of "Process Name" has been recorded with the value "New Value"There seems to be some kind of one way mapping going on between "server" and "custom" properties, but the really strange part is:I can update SOME server properties, others I cannot.I don't know a darn thing about SharePoint, other than as a dumb user. And getting any help from a SharePoint admin in my company is probably a very long shot...I checked all of Word's Built-in Properties and Custom Properties, I decided that none of them can be used to update the "Process Name" "server" property.How can I update this stubborn property? Most of the server properties I can update, a few I cannot.I see some articles referring to using what looks like "SharePoint objects." Do I need to download an SDK just to populate these properties? So far I've used Office automation, because I am running locally on the user's PC and pre-filling documents using the Word object model. All that is left is to finish populating the last couple of server properties after I copied the doc to a Sharepoint folder.
I have a webpage with a form that is used to edit some object. This object contains a Collection of other objects defined like this: Public Overridable Property Employees As List(Of Employee)
On a form I can delete an employee, add a new one or modify existing one. When I click save new values are sent to the server. On a server I check if the user exists. If exists then I modify its values, if it does not exist then I add it. All employees that exist on the server and were not sent are marked as deleted (State changed to EntityState.Deleted). I try to use the following code (dbCollection = database entities, newCollection = collection sent from the form):
[Code]...
This code does not work, because changing to EntityState.Deleted removes the object from collection, and for each loop breaks, since the collection is modified...I know that I can overcome this problem by using a for loop or adding objects to delete to some other list first, but I hope maybe there is a pattern that would make my code nicer.

However I've had some interest from a few customers that asked if I have a network version for site licencing.If my app did not save any data or write any reg entries, this might have been ok.

I also built in my own copy protection and trial function that stores data in the registry on the local computer.What would I need to do to enable my application to run on a server/network share, so that the only a serial number needed is for the server?

I have a client/server application set up that the client sends a word file to the server and then the server converts that word file to a .TIF and sends the image back.The stuff I have now works.Say if I sent the size of the file and the actual file byte() to the server back to back, would the NetworkStream contain both back to back? This what I though would happen. So I implemented a kind of 'turn' based interaction during the duration of the conversion process.

I have developed a VB.NET program using a strongly typed dataset. This dataset has its connection to a SQL Server 2008 R2. The software should now be additionally used offline. The database should be exported to a *.sdf database. If no connection to the SQL server is produced, the software have to try to connect to the *.sdf database.I would like to achieve:
1. Export the data in the SQL Server 2008 R2 database to a local *.sdf file.
2. This *.sdf file has to work as an alternate connection string in the strongly typed dataset.

View 1 RepliesI wrote a VB code to call a sp in sql server 2005, which returns a recordset as follows:Dim objRecordset As ADODB.Recordset Set objComm = New ADODB.Command
Set objRecordset = objComm.Execute If Not objRecordset.BOF And Not objRecordset.EOF Then
Set objRecordset = objRecordset.NextRecordset I need to continue to get next recordset since there are many select statements inside the sp which I need to get the data. The code works fine when I create the DSN using SQL Server but it does not work when using the connection string or SQL Server Native Client DSN. It either breaks at Set objRecordset = objComm.Execute ( connection string )or at If Not objRecordset.BOF And Not objRecordset.EOF Then(SQL native client )
I have worked on this for a couple of days now and could not figure it out.Is this a bug in SQL Native Client or something related to some configuration on the database side? IS there a way I can change the connection property to get this working using SQL native client or connection string?

View 1 RepliesI made a simple TCP server (I've found the example on the web) in VB to receive data from about 40 TCP clients.The clients are not synchronized but sends data about every 18 minutes; the problem is sometimes several clients sends data at the same moment, so I can't receive data.I also made a second program that reads the data (server program writes data on a file, read from the second program) scheduled.
My question is this: I've seen on the web examples about Multithreaded Server Socket Program, so I suppose this could manage my 40 clients (but now the clients are syncronized and send data at the same time in client mode) or is better get data (I have a central client that asks data to all 40 devices in server mode)?
Second question: can I make a single program where I run both TCP client and TCP server at the same time?
