String concatenation having null character
 

Hi to all

I'm trying to concatenate a array of bytes (0-255) to a single string,
like this:

Private conteudoBytes(2000) As Byte
Private conteudoStr As String

When I try to do:

For i = 0 To 2000
conteudoStr = conteudoStr & Chr(conteudoBytes(i))
Next i

conteudoStr have the concatenated string to the first null character
(0x00), exclusively. I don't know why it stops there.
conteudoBytes(2000) have the contents of a binary file. Am i doing
this the wrong way?

Sincere regards and thank you in advance for reading,
Marco

Maybe something like this:

Private conteudoBytes(2000) As Byte
Private conteudoStr*2001 As String



For i = 0 To 2000
if conteudoBytes(i) < 0 then
Mid(conteudoStr,i+1,1) = Chr(conteudoBytes(i))
end if
Next i

Are you sure that it stops there? If you were testing things by the
message box function, the msgbox function won't display past a null
character - but the data is there in the string nevertheless:

Sub test()
Dim S As String
S = "Hello" & Chr(0) & "World"
Debug.Print S 'prints "Hello World" in the immediate window
MsgBox S 'just displays "Hello"
MsgBox Mid(S, 7) 'displays "World" - the data is there and still
extractable
MsgBox Len(S) 'displays 11
End Sub

That's it !!

MsgBox() doesn't show chr(0), but the Immediate Window does.

Thanks alot, you saved me of alot of (debugging) time.

Thanks to all of you.
