Hello.

I'm no expert on using COM-Objects and the WinSock control...but could it be that it's a bad idea to close the Socket first, and then try to bind it?

to double check which line makes this error, i added some logs

          gLog.Write("1")
        winsock1.Close()
         gLog.Write("2")
        winsock1.LocalPort = 1223
         gLog.Write("3")
        winsock1.Bind()
         gLog.Write("4")

and when i checked the log after running the program. the log contain

1
2
3

after that .net error is showing.

so i changed winsock1.Close() at the beginning and tried

         gLog.Write("1")
        winsock1.LocalPort = 1223
        gLog.Write("2")
        winsock1.Bind()
        gLog.Write("3")

no change.. same error at same line.

then i try changing the port number and tried

         gLog.Write("1")
        winsock1.Close()
         gLog.Write("2")
        winsock1.LocalPort = 1227
         gLog.Write("3")
        winsock1.Bind()
        gLog.Write("4")

no change.. same error at same line.

if anyone have anyidea what this error means, then please help me... i search this error, but couldn't find any help. can you please help me to figure out what this error means...

thank in advance.

How many different forums did you post to? I make it at least 20!

If it's broken, inexplicable, rip it out and use something else.. Why are you using COM at all? .NET can do sockets..
