VS 2010 Navigate Through Records With TextBox DataBinding?
Jun 5, 2010
I 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 the following project. When I push the button "storage" and form appears I cannot navigate with the mouse in the textbox, if i write a word eg "George" cannot go the cursor in the middle of the word with the mouse, but only with the keyboard. Probably the not focus form (import product) blame but how can I focus that form?
Public Class mainMenu_Form1
Public Sub Panel1AddControl(ByVal control As Form)
control.TopLevel = False
Panel1.Controls.Add(control)
control.Left = (Panel1.Width - control.Width) / 2

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.

I 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

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:

I have a form with lots of textbox, and a dateTimePicker. All of these controls are binded to a JoinTableDataBindingSource. So when I wanted to insert a new value or update the values, I have to rebind all these controls to the respective tableBindingSource.So after saving all the values to database, I rebind them again to the JoinTableBindingSource to display the values accordingly.
All these works perfectly until I tried to bind the DateTimePicker. I am able to show the Date, insert new values to Date, and updating date.However, after all the binding and rebinding,whenever I tried to call tblJoinTruckTableAdapter.Fill (me.dataset. tblJoinTruck), All the textbox.Text becomes "Nothing". I am unable to show the values in the textbox.
Everything works when I commented off the binding and rebinding of dateTimePicker. I seriously have no idea what had happen.Below is the binding and rebinding of my dateTimePicker.'I have clear the databinding before adding this to point it back to its respective table.
dtpTareDate.DataBindings.Add(
New Binding("Value", TblTruckBindingSource, "dtTareDateTime"))
'After inserting or updating the values, I clear the binding and rebind it back to tblJoinTable.
dtpTareDate.DataBindings.Add(New Binding("Value", TblJoinTruckBindingSource, "dtTareDateTime"))[code].....

I seem to be having a problem binding the visibility property of a textbox to a database value using the advanced binding property.
I found this article (BUG: Inconsistent behavior when you bind the Visible property of a Windows Form control to a Boolean field) stating there is a bug in some older versions of the .net framework.
Does anyone know if this has been fixed in 4.0?

I'm relatively new to VB.NET and am having a problem when Databinding a Class to a Forms Controls. Basically within the Class, when Setting certain String Properties I heck that they are not Null/Empty and if they are Throw an Exception. The problem occurs when I bind the properties to textboxes - when the textbox is empty I expect an error to occur (which I will handle). So does anyone have any insight or solutions into why the exceptions are not being thrown when a textbox changed to an empty string?
A condensed example follows:
Dim a As New SomeClass("Random", "Text")
Dim f As New SomeForm(a)

I have a form, frm1 w/a combobox, cboLocations, which is being populated using a sql string. There is also a frm2 w/a series of textboxes and other comboboxes. I want it so that once a selection is made from cboLocations, the textboxes and comboboxes on frm 2 are populated with the corresponding data. Here is what I have so far:
frm1:
Public Class frmLocations
Dim conn As New SqlConnection("Data Source=f03d3s-dev01; Initial Catalog=dos_track;User Id=vbuser; Password=tran3;")
Dim depot_refnbr As Integer
Private Sub frmLocation_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
conn.Open()
[Code] .....
What's happening right now is that I make a selection from cboLocations on frm1 and click on the OK button, frm2 loads, but none of the textboxes are populating and one of the comboboxes, cboDepot, shows the different data when you click on the down arrow, but it's not displaying anything it its text field when frm2 loads.

I have a LINQ to SQL DataContext with all my tables and all my stored procedures in it. Let me first start off by saying that we are upgrading our project from an access project to a WPF project. So in the Access project you could set a forms datasource to a stored procedure and edit and add new information. So in my WPF project on the page load I call my stored procedure to return an ISingleResult and then call a function to set the binding on every single textbox on the form. One is there an easier way to do this and two what if I want to add a new record since the textbox's are binded to an ISingleResult?

I have a treeview populated with nodes, each of which, corresponds to a particular record in a DataSet.The desired behaviour, is... when a node is clicked inside the TreeView, if there's a record in the DataSet with with the same ID value as the name of the clicked node, then jump to that record.
