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.
im working on views that can help me navigate through records in a table. i have managed to execute an sql string to select the table i.e "select * from Users".i however want to build a "Previous" and "Next" command on the view but im mixed up on the navigation [code] Now all i need is code for going forward or backwards to a record.
View 1 RepliesI have a form that is used to navigate through records in a table one at a time. The form generates the number of textboxes required automatically. Navigating through the records is easy enough, but when I click the update button it comes up with the error: Object reference not set to an instance of an object.
Here is the code I have for when the Update button is clicked:
Dim con As New MySqlConnection
Dim da As New MySqlDataAdapter
Dim Query As New MySqlCommand

View 3 RepliesI have the following code i got from another thread and modified it to be able to navigate through records. The first record of the table is loaded into the textbox, but will not navigate. Tested already with a combox and worked, so i'm sure there is data in the bindingsource.
Me.BindingSource1.DataSource = MyData
Me.BindingSource1.DataMember = "ParentTable"
Me.BindingNavigator1.BindingSource = Me.BindingSource1

I have been trying to add First Previous Next Last buttons to my windows form (visual studio 2008), everything I have tried or found does not work.

This does not do what I thought it would do..I think that the problem is that when it sees System.Threading.Thread.Sleep(5000) everything stops for 5 secs .How can I make it go to google.com and then after 5 seconds, yahoo?
I would like for my program to navigate via textbox1.text with multiple lines and multiple url links inside of it. I know how to make the webbrowser1.navigate via textbox1.text with multiple lines, however I want my webbrowser to navigate to each url every 1-1.5 seconds once button1 is clicked. Yes, my webbrowser1 will navigate to the specified urls via the textbox1.text (multilines) with a button click, but I need the webbrowser1 to navigate in a order sequence from top to bottom of Textbox1.text (multiplelines) every 1 second. Here is the current code that I have to navigate via multilined textbox1.text control in order sequence:

View 8 RepliesI 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.

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.

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

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
