'Next' Button To Navigate Records?

May 30, 2009

I have been working on database programming alot over the last few weeks, and up tell the last few days I feel like no progress has been made. I didnt understand how to use the databinding features included in Visual Studio 2008 and had a hard time hard coding. It has been making much more sense but the only book I have found thus far to be extremely helpful is a VB 2005 book. I have the database connected and displaying the records, but cant get the next and previous button working correctly (I got rid of the navigator that automatically gets added when you add a new data source, and am trying to code my own buttons). The book instructed me to create a currencyManager, and I declared it CurrManager in my code.


CurrManager = Me.BindingContext(DsCompactDiscs, "tblCompactDiscs")

this is what I coded for the CurrManager and the following is the code for the next button.....

If CurrManager.Position < (CurrManager.Count - 1) Then
CurrManager.Position += 1
Else
MessageBox.Show("No more records.")
End If

I can click next all over and over again, and once it reaches the end it gives me the message i wanted it too, it just doesnt update the textbox with the next records data.

Why Does Master Detail Records Search Doesnt Bring Detail Records

Sep 29, 2009

I have a dataset containing 2 tables,Customers and Contacts. Just showing the master-detail is not a problem. Problem occurs when I try to search the master table to bring in the detail table. Searching the master table shows only the master record, but not the related detail records. Adding a 'findby' query on the detail table only shows the records.url.. Normally when the master table is filled, the detail record shows in a form.

Navigate Through XML In VB?

Apr 23, 2011

I'm having a few problems working with XML in Visual Basic.Net. My code's really long so I'm going to use a simplified version of it, basically my program's like this[code]...

So what I want to do is get the number of <tag> tags in the <section> tag and attribute that value to the NumberTags variable. Oh by the way <tag> tags may have other tags inside them but I only need the number of <tag> tags. I was using the MyIterator.Count command but then I remembered that that will only get the number of <category> tags in the XML File.

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.

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

Navigate Through DataTable?

May 30, 2009

I have a section of code that builds a table as the user enters information. I'm having trouble figuring out how to navigate through this table. There is a NEXT button and a BACK button. When they hit NEXT, either the next row loads, or the textboxes are emptied out. en they hit BACK, if there is text in the textboxes, save it, then load the row above current one. The code I have now will work until you go back too many times. You can go back, then forward, but it has trouble seeing the end of the table. And for some reason, I get phantom rows in between, but not every time. The rest of the code, where this table gets saved to the server, all works. Just navigating the table is giving me trouble. Here is what I have so far:

Private Sub nextNewTr()
Try
'check that the itemNo and item boxes have text
