Hi
I have created a new dataset based on a schema based on my database. I have added a new row a table in the dataset and am now trying to Insert this into the database. When I run it I do not get any errors, or do any records go into the database. What am I doing wrong?
<br />
newDataSet.Tables("tblHouse").Rows.Add(newAddress)<br />
newDataSet.AcceptChanges()<br />
Dim myTable As New DataTable = newDataSet.Tables("tblHouse")<br />
<br />
myAdapter2.Update(myTable)<br />

Don't execute AcceptChanges() until AFTER the .Update() is executed.

Thanks Dave. That has worked for when I am changing a record. What if I have added a new record.
The interface I have at the moment is a simple data bound form bound to a DataTable. The user presses the next button to add a new record. This is the code I used in the button
<br />
Me.BindingContext(myTable).AddNew()<br />
myTable.NewRow()<br />
When I try and save the new record to the database I get an
"System.Data.OleDb.OleDbException" error come up.
Many Thanks for the previous reply.

Don't call AddNew on the BindingContext object. You're not adding a Binding to anything, soooo...
Call NewRow on the table you want to add a row to. A new DataRow object will be created, according to the schema of the table, and returned. It does not add this row to the table!
Dim nr As DataRow
nr = myTable.NewRow()
You can then set the fields in the new DataRow to whatever you want, then just add it to the table:
myTable.Rows.Add(nr)

Cheers. Many thanks for that. The book I've got isn't all that good. Couldn't really find an example on the MSDN Either.
Thanks again

Uhhh... What? You're post appears to say that you're creating an MDIChild window in another application. This is just not possible.

dear friend...
if i have a form in vb.net such as (A) and another application in c language such as (B) how can i control the application (B) from the buttons based on form (A) and i mean of control :
1-run application B
2-minimize and mazimize form B
3-close form B
4- the most thing is make the form A always active that mean you cant use the appliation B except throught the form (A)

While it's entirely possible, your application sounds more complicated than it should be. For curiosity, why do you want to do it this way?

OK I WILL TELL U WHY?
i have old appllication build on C and i creat a interface with a vb.net form which let user to write somthing in the old system.the problem that i need to force the user to use the vb.net form to write in old application without click on old application and write on it .. that mean i need a way to make a old system behaive as a child of vb.net form ...do you know when we make as this example :
dim a as form1
a.showdialog()// that mean you cant edit a perant without close the child ..
that what i need .. i need to make the old system as a child which prevent the user modify except through the vb.lnet form
thanx alot for you ..

It looks like a multi-process application. The communication between your old and new has to go through certain IPC. There are several IPC mechanisms which you choose from, socket, shared memory, RPC, COM, etc.

Hi,
I have read that an array list stores objects. So, if an application creates Picturebox control objects at run time, can they be stored in an array list at run time?
Is an array list an array of objects or a linked list of objects?
Also, how do I pass the array list to a public sub as an argument?

hi
yes , you can consider "an array list an array of objects or a linked list of objects", also you can create an array of Picturebox !!
pass the array list like this :
Dim zzz As New ArrayList
zzz.Add("a")
zzz.Add("b")
zzz.Add("c")
Dim c As Integer = zzz.Count
SunName(zzz)
Dim dd As Integer = zzz.Count
.
.
Sub SunName(ByVal al As ArrayList)
al.Add("5")
End Sub
' notes that all the operations on arrays on general are done
' by referance , notes the count of the items before and after the call
' of the sub
hope its help
