VS 2008 : Database Save Update Remove?
May 19, 2010
i got a table in a datagrid, i did the whole connection with visual basic, the one to add a database, and now i see my mdb database in datasources and all..
this is my code
vb.net
Public Class InventarioIps
Private Sub InvIPS04_10BindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles InvIPS04_10BindingNavigatorSaveItem.Click
[code].....
I dont know if i have to create the connection to the table in this code so it can update,save,delete my info in the datagrid directly to the database source.?
When i save the info it only shows in the DATABASE thats in the BIN directory not the other one (the main one)...but either way when i close the whole project and open it again it loads the info from the main DATABASE and of course the BIN one changes witout the saved data?

When I'm trying to update or remove record from database I'm getting this error:
Syntax error (comma) in query expression 'Ime='Blagojce', Prezime='', Adresa='', Grad='', Telefonski_br='( ) -', Fax='( ) -', e_mail='''
Here is my connection string:
command.CommandText = "DELETE * FROM podatoci WHERE Ime='" & ime & "', Prezime='" & prezime & "', Adresa='" & adresa & "', Grad='" & grad & "', Telefonski_br='" & broj & "', Fax='" & fax & "', e_mail='" & email & "'"
where ime, prezime and so on are ListView selected items.

I'm using VB 2010 Express with a local Access DB. I am having trouble determing whether there are changes in a DataGridView to save back to the underlying DB.
The DB has been copied to the project directory and its properties (by selecting it in the Solution Explorer) include Copy to Output Directory: Copy Always, so I know that any changes I make when running a build will disappear on the next build. The problem I'm having is within a run / test session, working with the application.
The Access database has the following connection string, with Application scope:
Provider=Microsoft.Jet.OLEDB.4.0;Data Source="|DataDirectory|Component MI.mdb"

I have implemented the filestream feature of SQL Server 2008 in a VB.Net application. I can insert files, and then retrieve/view them just fine. However, I have huge problems trying to update a file. Eg. The user selects a file from the grid which I execute via process.start. If that file is a .txt file, the user may choose to edit it. In case that happens, I need to save the changed file back to the database. So far I have failed to do that.
What I do, is take the retrieved file, copy it (cause i got some errors about it being used), and then Process.Start it. After that, via .NET filestream, I convert the file to bytes and try to update the record. SQL Profiler and a manual SELECT on the varbinary(max) column tell me that the file is updated properly, but the very next try to retrieve it I get an unchanged file.
After that I also tried to update the file by changing its File-System Version, but the file still wouldn't seem to update. Does Anyone have a code sample of how I can achieve this operation? Like 500 sites on the internet have examples of how to Insert And Retrieve the file, but not a single example on how to update. This is how my second attempt of trying to update the file via the filesystem looks like. The code for inserting/retrieving is very similar and it works properly. [Code]

Now it updates when I press the update button and then it displays the data like it has updated the database, but when I close the program and run it. It displays the data as not updated WHY DOESN'T THE DATABASE UPDATE?Same with the Add and delete commands, I've almost finished my program but there's always a problem :...
Dim StudentID As Integer = Me.Lst.SelectedValue
Dim con As New SqlConnection("Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|StudentTeacherDB.mdf;;Integrated Security=SSPI")

I'm at the moment busy with a project for school. Well I have a datagridview that displays all of the employees within the company. But I want to be able to change, delete or add new employees in the datagridview and then save it in the actual database. I used this code to do that.
Me.Validate()
Me.TblPersonnelBindingSource.EndEdit()
Me.TableAdapterManager.UpdateAll(Me.DtsPersonnel)
But when I run my program and click on the save button I get this error message:
Application Exception was unhandled
TableAdapterManager contains no connection information. Set each TableAdapterManager TableAdapter property to a valid TableAdapter instance.How can I get around this? I think it has to do that my dataset exists out of 1 table but actually it contains items from 2 tables. Would this be the problem?I need to have the dataset like that though otherwise other parts of the program won't work.

This is in a BindingNavigator. I'm trying to get it to save to the database when i click the Save button. This is what I have so far:
vb Private Sub SaveToolStripButton1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SaveToolStripButton1.Click
[CODE]..............
It's telling me "Object reference not set to an instance of an object." on the dsNewRow declaration, I have no idea what that means. That same code (aside from different names) works fine another another project.

I have made a small form where I have bound textbox with records from database.Although my code for inserting and updating the record seems fine and working. But when I view the database, tables i see no inserts/updates made there. But When I run my application again, I see the records in the bound textbox but only for some seconds (for around 1 and half minutes), although they are not shown in the database (tables) actually.
When I close the application and run again it after 1-2 minutes there are no more records bound to the textbox, since no records at all.How can this be possible. I don't have any idea what's going on.
I have been using visual studio 2008 and sql server.Code I have been using for ::

I am currently puting together a data driven application just for fun and to get to know sql. The problem i am having is on my new customer form I cannot get the data in my text boxes to save into my database table at runtime. I simply have 4 textboxes and a save button the code for my save button is as follows:
Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click
Dim Connection As SqlConnection = MSDB.GetConnection
Dim mySqlCommand As SqlCommand = New SqlCommand
Connection.Open()
[Code] ....
All this does is bring up an error in runtime. How to get that to work when I press save the details in my text boxes are actually saved into my database table.
