VS 2008 - Error With Making Update To Database
Apr 2, 2009
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.

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.

Here is the part of the code that will error out. Specifically the
da.Update(ds, "info") Everything works fine with the datasets on the form and I can manipulate everything just fine. When it comes down to actually updating the changes to my database it errors out. Here is the entire code.

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 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

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?
