I'm not quite sure where to begin with this. This is basically how I'm trying to get it to work. I will enter the ID of a Hire Record in a textbox, hit the show hire record at which point it will materialise that hire records details in their associated textbox fields.I attached a screenshot of the form in question. I can also create a new record as you may be able to see by typing in the details and hitting create record (this is not a problem, i already understand how to do this), but I also want to be able to display an existing records details in the textboxes again

I am relatively new to the whole .NET thing, coming from a VB classic background.On my form I have a tabcontrol, with 4 tabs. Most of the code is handled using a shared handler, but for the others I have to write a handler for each.How can I optimize these routines into a single procedure?

My textboxes and labels are fine in design view, but when I switch over to Debug or Build, a couple of the textboxes are pushed together and the labels aren't in their original spots.Haven't seen this before and was wondering if anyone has any suggestions as to why and how to fix?

Here's the setup: I've created a class that represents a temperature and humidity monitor. This class handles all of its own operations (connects to the monitors via TCP, reads the temperature and humidity values at set intervals, logs the data, sends email notifications, etc.). I've got a single Windows form that has two textboxes for displaying the values of temp and humidity. When I start the application, I simply instantiate an object of this class and let it do its thing. Every five minutes, it opens up a socket connection, pulls in the data I want, sets the Temp and Humidity properties of the object to the values it obtained, and fires a DataUpdate event which is captured in an event handler in the Windows form.
When this event occurs, the textboxes on the form are updated with the values from the Temp and Humidity properties of the object. Works like a champ. However, I've been playing around with multithreading. Since a disconnected device will cause my entire application to block when it tries to connect, I decided to place the socket connection/data acquisition method into a separate thread. If it can't find the device, no big deal -- at least it doesn't lock up my UI. This thread is instantiated and started inside the object code, NOT the Windows form.
Here's my question, the socket connection/data acquisition method is run inside this new thread and sets the properties of the object when it's done. So, why do I get an illegal cross-thread exception on my Windows form, now, when I try to update the textboxes? It seems to me that the instance of the monitor class is running in the same thread as the Windows form. I only employ a separate thread when I want to run the socket connection/data acquisition method. Is my understanding flawed? I can display the updated property values in message boxes that are called from the Windows form. I just can't manipulate the textboxes.

I got 100+ textboxes that display record values. Most of the textboxes display correct values but several textboxes doesn't. These are the same textboxes. And they only display wrong values if I edit a record for the first time. After correcting the wrong values in the textboxes the first time, they display correct values in succeeding editing of records. Tried to compare their properties and all but they are the same with textboxes that worked...

I want it so every time I click an ITEM in the Listbox it displays ALL the data into the textbox. I know there's an easy way using table adapters and binding the listbox, but I'd prefer to do it this way for my project.
So this is what I got.
Lst.DataSource = ds
Lst.DisplayMember = "tblStudent.FirstName"
Lst.ValueMember = "tblStudent.StudentID"
[code]....
It only adds the first rows details to the text box when I click the second record the first rows details are still there.

In PHP I can use the following to stop HTML from rendering, so it actually displays html as text on the web page:
$html = "<div>Some text</div>";
echo htmlentities($html);
How do I do the same with asp.net pages (vb.net). I am using .NET 3.5.

Can anyone possibly take a look at my code (below) and tell me what I'm doing wrong? I have been sitting here for hours trying to figure it out. I'm very new at this and I'm thoroughly confused. I am using a book for Visual Studio "Programming in Visual Basic" and I have gone through all of the tutorials and code examples and followed them exactly (at least as far as I can tell). However, whenever I run the program, I am not getting the sum of the quantities I assigned to the constants showing up in"AccessoriesTxtBx" as I'm trying to. It shows up as $0.00 even when I have checked the boxes.[code]

I'm encountering some rather strange behavior in the VB2008 IDE regarding exceptions. I tried to explain what I need as best I can in the title, but I'm not sure there's a succinct way to describe it.I'm not the best programmer in the world to say the least, so sometimes I do things that generate exceptions when I try to run them (This is why we test things continually, right?). Typically, in addition to the Exception Assistant popping up and giving a suggestion, the IDE highlights the code that caused the Exception in the Code Window.
Well, today I went back to a project I had been working on after putting it on hold for awhile, and while the Exception Assistant still pops up when there's an exception, the IDE doesn't auto-scroll and highlight the offending code anymore. I have no idea why it does this, nor do I know how to fix it. Resetting settings from the Import and Export Settings Wizard didn't fix the problem, and neither did trying to reinstall VB2008. Is there some setting, obvious or otherwise, that would cause this?

I've written some code to get an image file from a OpenFileDialog, and then offset the X position of the image by -50, and then display that offset image in a panel. But for some reason, it is displaying the image twice inside that panel. Could someone please tell me how to get it to only display the offset image in the panel? I'm sure it's something simple, but I'm wracking my brain with this one.
If OpenFileDialog1.ShowDialog() = Windows.Forms.DialogResult.OK Then
Dim Bitmap As New Bitmap(OpenFileDialog1.FileName)

i know there are no "control arrays" in vb.net. i do come from vb6, and im trying my way now within bv.net, so please be gentel...
if someone could please post a simple code to do the following, it would be great:
i have 3 textboxes called txtBet1, txtBet2 and txtBet3.
i have another 3 texboxes called txtResult1, txtResult2, txtResult3.
so i want to have one loop code, to get the value in txtBet1, calculate somethings, and put it into txtResult1.text.
i know it's basic, but i tried using this sample here as a reference, but its not really understandable for me, because its not really choosing the exact control i want to address...
this is from Microsoft website - a comparison between vb6 and vb.net:
"' Visual Basic 6.0
Private Sub ClearText()
For i = 0 To Text1().UBound

I am creating a form application that should display information from one dataset into individual textboxes (ie. system name, system id, location name, location id). The textboxes populate upon the selection of a pair of cascading combo boxes. So, the user first selects a system name from the first combobox, then that selection will populate the second combo box for the locations of that system. (This means that each system may have more than one location.) Once the location is selected, each of the 4 textbox should populate with the corresponding data but I'm not quite sure how to write the code..

1) Lets say I have three textboxes: TextBox1 TextBox2 and TextBox3.
Public Sub loopthing (ByVal input1, ByVal input2, ByVal input3)
For i = 1 To 3
TextBox(i).Text = input(i)[code]....
I know that the (i)-thing will not work, but my question is if it's possible somehow to set the three textboxes text to different variables using only one line of code (Like my attempt above).
2)How can I do so that when I click a tabpage on runtime, a certain textbox is highlighted and ready to write without a mouse-click?
I've tried the tabpage's GotFocus- and Enter-events, and writing
TextBox1.Select()
there, but it only works the first time I enter that spesific tabpage.
