Unable To Flip Through The Records In That One Text Box?
Nov 7, 2009
I have a blank form, and I've added a really simple Access database with two tables with two columns each. If I click and drag the name of one of the columns, and drop it on the form, I get a label and a textbox.
I was assuming that since the load procedure already had Me.WhateverTableAdapter.Fill in there, that when I pressed the green arrow to run the program, I'd be able to flip through the records in the column.
When I click "preview data", I do see the data is there, but when I run the program, it says 0 records and none load. Is there something else I have to do to be able to flip through the records in that one text box?

When I modify and delete data in a DataGridView, I get the error:
The record cannot be deleted or changed because table 'Table Name' includes related records.
but I can add new data, only cannot modify and delete data.

In my application, I open a "Customer Details" form and on confirming I have to delete all records from other 2 tables (Order & OrderDetails) of the database. I am not able to delete records. It somehow stops by on - ordDetAdap.Update(ordDetDs) . The code is as follows :
[Code]...
There may be N number of Orders and each order may have N number of OrderRedetails. There are rows and also shows proper data in MsgBox, also row.Delete works fine, BUT why does it stop at Update(OrdDetDs) I can't make out. Any idea where am I going wrong.
Also Is their any easy way out to delete all records using just a single statement providing OrderId from OrderDetails table ? As of there are 10 rows of a single order, then For loop will iterate 10 times and delete 10 rows, instead if I can delete all 10 rows at once would be beneficial.

I have a program which I am converting from VB6 to VB2010 this is also my first venture into sql. I have read many of the examples to try to get to grips with deleting records including those in this forum by imcilhinney
My problem is that I want to delete all but one of the records when the user presses a button, everything goes well until the 'ExecuteNonQuery' is reached.

I am building a custom search control in VB.NET and came across a problem getting distinct records into my datagridview. I want to bring exact matches back first so I run 2 of the same query on the same table with a slight difference:
select ... like "code%"
select ... like "%code%"
I have a datatable that I need to get distinct records from; I am append records from a sql query to the end of the datatable so I cannot use a union in sql to return the dataset (I want to preserve the order which the rows are added) I have been using this which is working fine for 2 fields:
dt2 = dt.DefaultView.ToTable(True, "Code", "Name")
But when I have 3 (or more) fields I get duplicates ONLY for the row I am querying:
dt2 = dt.DefaultView.ToTable(True, "Code", "Name", "Initial")
select ... like "initial%"
select ... like "%intial%"
I am clearing the datagridview.source before rebuilding this. Is there a way to get the distinct rows this way or should I just build something myself to remove the duplicates from the second datatable before appending them to the new table?
