About the closest you're going to get, without actually saving the file to do it, is to use the length of the RTF property.
Dim length As Integer = RichTextBox1.Rtf.Length

I have made a program and it has a Rich Text Box. I have a button called "TblBtn" and when its clicked I want it to insert text at the cursor location on the Rich Text Box. Using VB 2005. Any advice?
In the end we're all just the same

You might want to try something like this:
rtb.SelectionStart = 100;
rtb.SelectionLength = 0;
rtb.SelectedText = "text to insert"

Dim myFileName As String
Dim myFile As System.IO.FileInfo

myFile = New System.IO.FileInfo(fileName:=tmpstr)
stream = File.Create(tmpstr)
Dim info As Byte() = New UTF8Encoding(True).GetBytes("hello")
' Add some information to the file.
stream.Write(info, 0, info.Length)
sream.Close()

Uhhh...This is very confusing. The code you posted doesn't read anything. It writes a string of bytes to a file and that's about it.

That's because you don't read anything from USB. It's a bus, not a port. You read data from the devices attached to the USB bus, but how you do that depends entirely on the device itself and what methods it's driver exposes.

I've not used Crystal for many years - but I seem to remember that there was an option for executing a "pass-through" query that would allow you to use native SQL-Server syntax (ie. "EXEC MyStoredProc 'ABC'").

I am trying to send an email using my program. How Many ways are ther to do it? Which is the best way, currently i have:
Dim m As New MailMessage(FromtextBox.Text, ToTextBox.Text, SubjectTextBox.Text, BodyTextBox.Text)<br />
Dim a As New Attachment(My.Settings.CurrentList)<br />
Dim c As New SmtpClient<br />
m.Attachments.Add(a)<br />
c.Host = ""<br />
c.Send(m)
My main problem however is that i have no host info, is there anyway to access the host information on the machine the program is running on and, if not, is there an alternative, other than manuel user entry?

If you don't have the host info, you need to use MAPI, there are .NET MAPI wrappers on the web.

You make it sound easy, but i'm new to sending mail and have no idea about MAPI. Is there anyway to programatically extract Host Info or should I just add a user customisable setting to my program.
P.S. What Host Info is actually required to send an email, does it include password etc, or just the server.

I've decided to go with having the user enter the server setting. Then its saved and is used automatically until changed.

You must using dataset and binding it with datagrid

Hello all!
I can't beleive I can't get this, but here it goes. I want to reset a integer number that used for a time. So at the top I have
Public mysec As Integer = 15
Then I have this for my timer
Private Sub tmrGame_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tmrGame.Tick<br />
Threading.Thread.SpinWait(1000)<br />
mysec = mysec - 1<br />
lblcdClock.Text = ":" & mysec<br />
If mysec > 15 Then<br />
mysec = 0<br />
End If<br />
If mysec = -1 Then<br />
tmrGame.Stop()<br />
lblcdClock.Text = ":" & 0<br />
Threading.Thread.Sleep(2000)<br />
lblcdClock.Text = ":" & 15<br />
End If<br />
End Sub
How can I reset "mysec" to 15 so when the time stops, and I start it agin, it start from 15? Using VS 2003.
Thanks!

The method that starts the timer should reset the variable.
rudemusik wrote: If mysec = -1
if mysec < 0 is a safer check to make, just in case.
So, if it goes over 15, it gets reset to 0, and on the next iteration, it will end ?

Hi Christian!
It's actually counting down from 15. I have mysec = -1 so that a 0 will show. After the 0 shows, I set the label to 15. But it doesn't change my intger, so if it starts again, it will start with -1, -2 and so on. How can I change the 0 to a 15 as if if I were reloading the form to kick off the "Public mysec As Integer = 15" line.
Thanks!
Rudy
