Chr and ChrB.. Why doesn't work????

Hi everyone,
I have tried a sample code in a form with 2 buttons and 3 textfields:

Private Sub Command1_Click()
Text3.Text = Asc(Text1.Text)
End Sub

Private Sub Command2_Click()
If Text3.Text > 31 Then
Text2.Text = Chr(Text3.Text)
Else
Text2.Text = ChrB(Text3.Text)
End If
End Sub

This should work, but when i put in Text3 a value under 31, in Text2 nothing appears. Can you help me please?

not surprising really, Ascii char 31 is not supported by windows, in other words some fonts will show nothing.

install the MSDN library if you havent already and use it: go to the index and type "Ascii Character Codes", and you'll get a map of them.

Ahi ahi... this is a bad thing... any idea on how to solve this problem?

It's best to stay away from character's 0-31 and 127-159.

It's in the VB5 help file (at least). Also, try Character Map for all the characters 32->256.

Parksie: You are forgetting characters 127-159 are not supported by Windows

Override:

Code:

---

If Not (Asc(Text1) > 32 And Asc(Text1) < 127) Or Asc(Text1) > 159 Then
    'Key is invalid
End If

---

Strange. Then how come in Character Map, when selecting Times New Roman, I have a total of 224 characters displayed?

Yes, actually you're right, but 127-159, for the most part, are only supported with TTF. If you try it with a Non-TTF (which includes the standard MS Sans Serif) then chances are it won't work.

Hmm. It's got characters for those as well! I tried MS Sans Serif, MS Serif, Terminal, Fixedsys and some others and they all had those characters supported. Although most of them missed 127->159 out. The chars from 160->255 seemed to be stuff like é and ô.

That's strange, i have tried chars beetween 127 - 159 and
actually they don't give me any kind of problem. They work
well, i am using Terminal Font.
Just another question:
I have to send to a multiline textfield a simulation of an
Enter keystroke.
If i want to add a simple character then i do
Text1.Text + "a"
but how to send a enter keystroke?
Text1.Text + ENTER
Does not work! Eheh! ;-)))

For ENTER use:

Code:

---

'Either this
Text1.Text = Text1.Text & vbNewLine
'Or this
Text1.Text = Text1.Text & vbCrLf
