Navigate From One Record To The Next?

Jul 18, 2009

I'm new to VB and have bought a book (Database Access with Visual Basic)that I'm trying to follow but ran into problem right away.Have created a table (tblCustomer) and populated it with a few lines of data then I have a form with two textboxes connected to the table. So far no problem I can see the first row of the table.Next step was to create two buttons to be able to navigate in the table, one forward and one backward but nothing happen when I click on one of these buttons.

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Me.BindingContext(NoveltyDataSet, "tblCustomer").Position += 1

Foreign Key Constraint Error / Parent Record Does Exist But Won't Let Child Record Be Created

Feb 21, 2010

While I've previously many years of relational databases and procedural languages, I'm stumbling with Visual Basic. In this problem, the simple situation is that I have two files, parent and child. The primary key of the parent file (Area file) is linked by a relation to one of the two fields that makes up the primary key in the child file (Project file) (unique key is formed from 'area' and 'project'). I have the default table adapters created on both files. I have created two maintenance forms showing one each of the two files in datagrid view format.I can create some records in the Parent (Area) file, but when I try to create a record in the child (Project) file, using one of the valid key values from the Area file, I get the 'ForeignKeyConstraint [relation name] requires the child key values [actual value] to exist in the parent table' which I'm absolutely definitely sure it does.

I haven't done any actual coding for those two maintenance forms, just dragged-and-dropped the files from the data sources screen onto separate forms so it creates the controls itself. But I can't work out, if it already knows the data does exist because I can load it back in to the Area maintence form, why it can't check itself to find out the record does exist. Why does it think the record from the parent record doesn't exist? It does exactly the same thing, whether or not the database is in access or SQL Server Express. I have all the latest updates.

Adding Association (link Table Record) Without Creating A New Related Record?

Jul 31, 2011

I have two tables Products and Categories with a many to many relationship. I am trying to copy the categories linked to one product (OriginalProduct) to another product (newProduct). The problem is when I execute the SaveChanges() method, I not only get the records in my linking table, but it also creates another copy of the categories in the categories table. I've tried this in many ways but here are the last couple that I've attempted:

' Copy Product/Categories
For Each oneProdCategory In OriginalProduct.Categories
Dim relatedCategory = _productContext.GetObjectByKey(New EntityKey ("ProductInfoEntities.Categories", "RecordId", oneProdCategory.RecordId))

Event After Next Record Has Populated Child Record In A Datagrid?

May 27, 2011

Visual Studio Pro 2010 Win 7 64 bit running bootstrapped to a MacBook Pro i5 (blasphemer!!!) works really well though!!New to vb.net, have used vb6 for several years and finding the transition interesting to say the least.I have an access database with a vb.net front end all auto bound by the connection and binding wizards (I know, I know...) Not too complicated, but a simple 2 table related db. On the form the parent table shows customer details with the child table related and displayed by datagrid. I have a field in the child table for images and I have figured out how to store and retrieve images to the db. I am using the datagrid.rowheadermouseclick event to reload the picturebox on the main form as I click down the child table datagrid. Now I need to be able to click the bindingnavigator, go to the next record and have the program reload the image for the next child record. The problem is I'm trying to use an event from either the datagrid or bindingnavigator to reload the picturebox in the child table after moving to the next record, but all of the events I am trying are firing before the next record is moved to and therefor the logic I'm using to retrieve the image from the db is not working.

Anyone with an idea on how to move to the next record and then run my logic to populate the picturebox? What events might I use that fire after the next record has been populated? I know this is probably not that hard, but I have been racking my brain all day now.

Retrieve Found Record Into Own Record Buffer?

Sep 12, 2010

I have now wasted over two days going round & round in circles with the pathetic excuse for a Help System Microsoft now makes us put up with (& nearly blown my monthly broadband data cap doing so).I have lost count of the links that do not exist.The Give Feedback option also does not work (I do not like Microsoft Outlook, & in spite of having set Windows Mail as the default mail that doesn't work either!).Every VB example I have downloaded has failed to operate as it should (if at all), so surprise, surprise nor does my implementation of what they say is how to do it! please give me the "exec summary" version of what I need, ON ONE PAGE which is: Correct way (& syntax) to (in VB code):

1 Open an existing SQL compact 3.5 database THAT IS WHERE I SPECIFY - NOT WHERE the wizards keep saying it is(it against my instructions)!

2 Search to see if a particular record exists in the database (eg WHERE ColumnName. FieldContents = ContentsImLookingFor)?

3 Retrieve the found record into my own record buffer?

3 Add the record if it does not exist?

4 Change the record?

5 Delete the record?

6 Close the database?

The rest I will do MY WAY, a thousand times faster & more efficiently than anything I've seen "documented" so far. Surely that is not a huge ask requiring GBs of "Help" garbage leading nowhere?I've only been programming for 25 years (but not in this environment),
