Hi, I can send a single character when I press a command button in VB.

Here is the code

Code:

Private Sub Command1_Click()
MSComm1.Output = "A" + Chr(13)
End Sub

Now I need to send a string which is typed in the textbox when I pressed the command button. Can anybody help me out to do this?

Thanks

Private Sub Command1_Click()
    MSComm1.Output = Text1.Text & vbCr
End Sub

Hi Mike thats what I was looking, I couldn't find this on the net.

Ahh this will send a string what I type in the Text1 box.

I'll try to add your code.Can I change the character length also,I mean character length (Word) must not exceed 10 characters.Its never mind I'll try to solve that out.

Thanks Mike

You could do,

Code:

Private Sub Command1_Click()
Dim Temp As String
    Temp = Text1.Text
    If Len(Temp) > 10 Then Temp = Left(Temp, 10)
    MSComm1.Output = Temp & vbCr
End Sub

Hi Mike now I got it.Thanks for the superb code.All I understand except the Left(Temp, 10) part.Does it move left when it receive 11 characters?So every time it is a below 10 letter word.

Left just returns a number of characters from the beginning of the string and so, Temp=Left("Hello World",5) would result in Temp containing "Hello".
