[rajeshnrh74]

Hi Gurus,
I need one solution
I'm using VB6, one of its Form contains a TextBox
What i need is whatever characters I type in it that
should be highlighted
ex

First when I type "a" -> "a" should be selected
second when I type "b" -> "ab" should be selected
third when I type "c" -> "abc" should be selected
fourth when I type "d" -> "abcd" should be selected
likewise it go.

ie overall characters upto the cursor end should be selected.

Hi,

To Highlight Text in a Textbox, you can use this code:

[code=vb]
Text1.SelStart =0
Text1.SelLength = Len(Text1.Text)
[/code]

Write this in Got_Focus Event.
If you write this in Change Event (as per your Requirement),
The Highlighted Text would keep on deleting with every key typed..
Not very sure, why do you have such a requirement...

Veena,
Thnks for your response.
Actually my work behind reading Barcode thru Barcode Reader into the
TextBox, The Maxlength of the TextBox is 12.
If I Input some characters manually into the TextBox Say "abc" (without quotes)
now the cursor is in 4th place from there it won't allow Barcode Reader to read.
It should start from 1st place only by erasing already existing 3 characters.
This is my situation.

Can U come out of this.

Hi,

Then, write the code (my previous post) in got_focus event, I think it would solve your problem..

Hi,

Maybe You can add this code on Change event in your textbox

Dim ChrSet As String, chrpos As Integer, getchr As String
ChrSet = Text1.Text
If IsNumeric(ChrSet) = False Then
    If Len(ChrSet) <> 0 Then
        chrpos = InStr(1, ChrSet, Right(ChrSet, 1), vbTextCompare)
        getchr = Right(ChrSet, 1)
        Text1.SelStart = chrpos - 1
        Text1.SelLength = Len(getchr)
    End If
End If

This Code Will Highlight the last character, and you replaced it with the right for for you card reader!
