I am getting over lapping data while sending and receiving data in a tcp listener I am working on. How does one reset or clear the buffer or bytes so they don't carry over to the next send or receive?
Thanks in advance!
Partial Example:
' Client sends:
TempS = curAdd.ToString & ".............. ............... ............... ............... ............... ............... ............"
' Padding the end of the IP address so I can trim(".") when received because I couldn't trim the free space at the end.
Buffer = System.Text.Enc oding.Default.G etBytes(TempS.T oString)
Client.GetStrea m().Write(Buffe r, 0, Buffer.Length)
' The Server Receives:
While Not StopListener
If CurSocket.Avail able > 0 Then
' 1. Receive IP Address from client:
Bytes = CurSocket.Recei ve(Buffer, Buffer.Length, 0)
SyncLock CurThread
clientV = (System.Text.En coding.Default. GetString(Buffe r)).ToString
clientV = clientV.Trim(". ")
Buffer.Clear(Bu ffer, Buffer.Length, 0)
On the next send / receive I am getting leftover ........... in the string.
THANKS! 3 1469
Kenneth,
I'm not sure I understand the problem, but ... Buffer = System.Text.Enc oding.Default.G etBytes(TempS.T oString)
I'd recommend using an encoding other than Default (such as UTF-8),
because the default can be different on different systems.
Buffer.Clear(B uffer, Buffer.Length, 0)
Since you specify a length of xero here, nothing will be cleared.

Please reply only to the newsgroup.
When I send this: TempS = curAdd.ToString &
".............. ............... ............... ............... ............... ............... ..........."
to the server I then trim(".") to get rid of the periods. Then the server
sends four messages back to the client depending on the processes that takes
place. Finally the client Sends: "PCNAME-Scheduled" to the server and the
server receives "........ti ng". It appears as though its pieces of previous
buffer information.
I hope I explained the issue!
Thanks for the HELP!

HI;
I have a table where the user is entering data which shows scheduling for member of teams.
One problem we have encountered is that sometimes the inputter (is this a word) puts in
dates for an individual that overlap, creating all sorts of problems. One record is
entered for each scheduled event (each one is a day in length or more), so that an
individual will have multiple events on the table.
For the purposes of this question,...

I hacked this together this morning so that I could shift my out-of-
space code away from the rest of my logic. I wanted to allow array
syntax on my dynamic buffers, so I manually created a struct with
malloc() and judicious use of void* pointers.
I decided to post it because stuff like this is breeding ground for
UB, and this group is good at finding it. (I had a dentist analogy
for that, but it didn't work out.)
Here's my code:

Hi,
I got a large text string, and a bunch of regular expression patterns
i need to find within the string. in other words, to find all the

is, if I got 500 different patterns, this means 500 searches on the

up? In other words, I am looking to do what the old 'LEX' tool in unix

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
