Hi All,
I'm trying to write a small sub/function to replace some (invalid) character
in a combo box, or may be even text box. For example, I have several combo
boxes that allows user to select a time value, i.e. 21:30, however I also
want to allow them to enter a time, as a result I want to replace comma,
fullstop etc with a colon ":". I've done this in VB6 keypress event,
however with the "sender", "e" in .net I'm a bit lost... I don't have much
experience in .net could you guys give me some help?
Thanks!

Kay,
Here is an autocomplete sample for a combobox, in my idea are all the
ingredients in that to make what you want. (It begins with building a
sample). http://www.vb-tips.com/dbPages.aspx?...f-c22411591992
I hope this helps,

Hi Cor & all,
Core thanks for your response, I have a look on your web site, but I think
it may be a bit difficult if I want to use it for a text box - after I think
again what I really want - if it's possible I want to create a function,
with a papramater, then check whether it's a valid character, i.e. in this
case ":" & number are valid, if not cancel the character entered, or replace
with other character....um ... that sounds good to me but if you guys have a
better advice please tell me!! So now the problem I have is how to capture
the character just entered....

Kay,
Have a look at the thenthousand samples about a numeric textbox on Internet
by using Google.
I have not set this one on our site, because there is nothing in it for
pushing the del key etc.
Especially for your question, use the keyup event most people want to use
the key down, which gives less information in the KeyEventArgs.
\\\\
Private Sub Form1_Load(ByVa l sender As System.Object, _
ByVal e As System.EventArg s) Handles MyBase.Load
Me.TextBox1.Max Length = 10
End Sub
Private Sub textbox1_KeyUp( ByVal sender As Object, _
ByVal e As System.Windows. Forms.KeyEventA rgs) Handles textbox1.KeyUp
If e.KeyValue <8 Then
If Not IsNumeric(TextB ox1.Text) Then
If TextBox1.Text.L ength 0 Then
MessageBox.Show ("Only numeric is allowed")
TextBox1.Select ionStart = TextBox1.Text.L ength - 1
TextBox1.Select ionLength = 1
End If
End If
End If

Hi Cor,
Thanks for your help! Can I ask one more question? :P
Is there something like an ASCII table that represent a KeyValue? Coz I
want to capture more characters other than numbers. Tried to search through
the help but it didn't tell much.... may be I'm looking at the wrong
direction...

Kay,
No I thought you know that, you see in the latest sample the 8 but there are
more therefore I said it was not complete.
Therefore I said have a look for a numeric textbox
This is a nice solution with the control characters http://groups.google.com/group/micro...f7a8450e71ebf6
I took from Internet the first table I could find. I know that there is a
nicer one on MSDN, but with the same search information I could not find it
there, maybe you can try that yourself. http://www.lookuptables.com/
I hope this helps,

I have a form in c#. I want whenever a user presses return
on a text box, combo box or numericupdown control the key
press will be trapped and replaced with a tab character
forcing the user to move to the next control. I can trap
for the character but can only block the return and then
do a sendkeys for tab.
Surely there is a way to change the character that is
trapped.
