TCPStartup() not receiving all the data.

4 posts in this topic

I'm using something like this...

TCPStartup()
Local $ConnectedSocket, $szData
;Local $szIPADDRESS = @IPAddress1
Local $szIPADDRESS = TCPNameToIP ( $_MonitorNameIP )
Local $nPORT = 65534
$ConnectedSocket = -1
$ConnectedSocket = TCPConnect($szIPADDRESS, $nPORT)
If @error Then
FileWriteLine(@ScriptDir & "\Errors.log","TCPConnect failed with WSA error: " & @error) 
Else
$szData = $_SendData
;if $szData = "" then _GoConnect()
TCPSend($ConnectedSocket, StringToBinary($szData, 4))
EndIf

to send data. It is sending, but not all of it. the variable $_SendData I guess does get pretty big. I'm wondering if I'm hitting some sort of variable size limit or a TCP send limit or something. And if anyone knows of a work around.

Hi,

What is the receive code? Are you sure you have not set a byte limit shorter than the length you are sending ?

Br, FireFox.

recieving code had this line

$recv = TCPRecv($ConnectedSocket, 2048)

changed 2048 to 1024000 * 5 for 5 MB. Works now, thanks!

Where would I have set a byte limit?

I don't know much about this function, but from looking at the help file, I'd say here.

$recv = TCPRecv($ConnectedSocket, 2048)

EDIT: If you want to receive more than 2048 characters, you'd need to put this into a loop until you get an error indicating that the connection has closed.

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.
