View 1 RepliesI am developing a chat application using online connection to a mysql databbase. But i am facing a problem. After 10 minutes, MySQL closes all the chat connections because of the 600 seconds timeout (has been set by the host service i am using). I don't understand why is that happening cause every piece of my code which needs data from the database opens and closes the connection (i mean that it dosn't maintain the connection after the query's execution). If i .close() and .dispose() the connection, it still appears in mysql at sleep mode (it terminates only if i exit the program).
Dim MySQLCon as New MySQLConnection
Dim MySQLCom as New MySQLCom

im trying to make a little application that will read an fps server chat log.the chat logs are plain text files that come in the format :
Billy says: yada yada yada
Bob says: mooo
on certain key phrases (which will be user defined) it will reply (also user defined) now my problems. (there are many). most of which stem from not actually knowing any syntax for this language.firstly im suffering something of a huge brain fart with trying to read only the last line. i have it currently reading though the whole file and counting line numbers but then i just hit a wall . what do i do with the line number? i cant find a simple way to stop and come then have it check again after a couple of seconds for a new line? allegedly filestream can seek the end of the file however all my attempts to do anything with filestream have met with absolutle failure.
this is what i currently have for this, and it works to some degree
FileReader = New IO.StreamReader(OpenFileDialog1.FileName)
Do While FileReader.Peek <> -1
txtln = FileReader.ReadLine()
[code]....
i have the remnants of both the options ive considered in there, and its almost doing what i need it to . i just have no idea what to put into the last section to make it wait for another line to be added to the text file, or use the linenumber to make it check back from there for more lines. i cant seem to find a wait/sleep/pause so i just dont know.
my other problem is one of file access. i am aware of some properties of filestream that allow for a shared read/write access for other programs . however as i stated before . i have had no success even getting this simple peice of code to work with filestream.

View 1 RepliesI have been trying for years making a network app.I need linked to a video or something, mainly on msdn or some microsoft site, because youtube created videos for coding aren't all that helpful as most of the microsoft made videos.
I need not linked to things like multi-user tcp chat application, as i have looked at these, and even found no code solution, but the no code doesn't allow too much customization and hard to deal with data received to make your own commands send and receive and have events for them.
The multi-user tcp chat application, it doesn't explain anything, just gives you the code for you to look at, and well, it's hard to understand.
