[RESOLVED] Winsock data problem

[rolahara]

Im building a client server app, everything works just fine the problem is that sometimes when i send multiple data to the server of from the servr to the client, the strings of two or more events overlap for example in form_load i request the server for the list of users and the list of online users at the same time so it would be:

winsock.senddata "/Userlist/"
doevents
doevents
winsock.senddata "/OnlineUsers/"
doevents
doevents

the problem is that somtimes the data arrives to the server as one string instead of two separate command, for example it arrives like:
"/Userlist//OnlineUsers/"... i thought that DoEvents would handle that but apparently it didnt, is there any other way i can take care of that... thnx

That's a common problem, you have to check, the work around I used is checking each message received if it consists of more then one message. You need to have a characteristic ending sign to do that.

Split Them
Example:
wsk.Senddata "NAME" & "/UserList/"
doevents
wsk.senddata "NAME" & "/OnlineUsers/"


on DataArrival
dim SplitData() as Variant, I%, Buffer$
wsk.getdata buffer
SplitData = split(Data, "NAME")
for i = 1 to ubound(splitdata)
debug.print splitdata(i)
next i

This is the easy way to do it i guess, i could be wrong

I had that problem too. Like already mentioned, you'll either have to add a specific character symbol at the end of the string being sent so you can then split them at the receving end. The other way I managed to get around this was to use a timer. The timer will cause enough of a delay to make sure that the data is sent one message at a time. The slowest I've set my timer to is half a second and the receving end gets the string one at a time and not bunched up.

Take a look at this thread, we had a small discussion on this:

The proper/best way is to use a delimiter, like drivenbywhat said.

Avoid using a timer. It slows down your program for no reason, and is not 100% reliable.
