You are mixing you data types.
You need a property for each field in the table
You need a private var for each field
then you can populate the object
Private Overloads Sub RowToObject(ByVal oTable As DataTable)<br />
If (IsNothing(oTable) OrElse oTable.Rows.Count = 0) Then 'no table not row then empty the object<br />
mvPFClassID = Nothing<br />
mvPFClass = Nothing<br />
mvModified = Nothing<br />
mvModifiedBy = Nothing<br />
Else<br />
Dim oRow As DataRow = oTable.Rows(0)'get the first row from the table<br />
mvPFClassID = IIf(IsDBNull(oRow("PFClassID")), 0, oRow("PFClassID"))'load the properties via the private vars<br />
mvPFClass = oRow("PFClass") & ""<br />
mvModified = IIf(IsDBNull(oRow("Modified")), Nothing, oRow("Modified"))<br />
mvModifiedBy = oRow("ModifiedBy") & ""<br />
End If

Open Image file in Binary mode and send it through serial port.
and receive also in Binary mode.
put your serial port encoding to UTF-8
use this for put UTF-8 Encoding
SerialPort1.Encoding = System.Text.Encoding.GetEncoding(1252)

There is an on screen keyboard CP article. Getting it to work between apps, is probably a little complex for you right now.

In order to press a button in one application, it needs to have the input focus. Since your keyboard now has the focus, what was the last control to have the focus??? Hint: There's no function or method that will tell you that. So where do you send the key stroke??

Please help me i've seen it done before i just dont know how to code it in i think possibly you could set it so when a button is pressed it opens a microsoft word document and then all the other buttons simply Word.Application = Word.Application & button1.Text but word. Application does not seem to work in vb 2008 express edition.
Can no one help me

This should be a softball for some of you.
I want to have all of the text in a textbox highlighted when I enter (click, tab, etc) into it. How do you do that?
Thanks in advance!

Use the selectionstart and selectionlength properties, set them to 0 and the length property of the text.

Create a handler for the GotFocus event & use SelectAll method. This works for tabbing between controls. Select all on click is a difficult, because the control uses mouseDown to set the caret. You could handle the MouseDown event in the same way as GotFocus & see if you like the result.

You'd have to handle the ItemChecked event of the ListView, which will give you the item that was clicked on. You'd then have to set a static flag in the event handler that will signal that you are changing check marks. Iterate over the items in the list, changing each check mark, then reset the flag. Since changing the check mark will fire the same event again, the handler code has to start by check that flag. If it's set, then the handler code can exit without making any changes.
But, wouldn't this be a job for RadioButtons?? After all, this is exactly what they do.

Hello,
Please try this code. I believe this should assist you.
<br />
Private Sub ListView1_ItemCheck(ByVal sender As Object, ByVal e As System.Windows.Forms.ItemCheckEventArgs) Handles ListView1.ItemCheck<br />
<br />
For i As Integer = 0 To Me.ListView1.Items.Count - 1<br />
<br />
If i <> e.Index Then<br />
<br />
Me.ListView1.Items(i).Checked = False<br />
<br />
End If<br />
<br />
Next<br />
<br />
End Sub<br />
<br />
Regards,
Allen

For each oItem as Listview item in LVData.items<br />

No, you can't. Opacity only applies to the entire form, not controls. Currently, you'd have to use WPF to do this.

I am developing in VS2008 Express Edition using ASP.net and VB.net. I would like to record the local time when something happens in the application (say a button is pressed). If you use the Now() function, it returns the Servers time. I want the time on the local computer. I have searched high and low and am baffled this is not needed more often. There is practically no mention of it on the web. Any pointers would be appreciated.
Thanks,
Karl Tomecek

This question really belongs in the ASP.NET forum. It has nothing to do with VB.NET at all.
There is nothing that the browser sends to your ASP.NET code that will tell you what timezone the client is in. You'll probably have to use JavaScript code in the page to set a hidden field with the clients time when the form is submitted back to your server to get the client time, or at least the timezone the client is in. Your ASP.NET code would then have to parse the date time value found in the hidden field to get at this information.

I beleive it is available in the environment variables which can be got at via JS
