I wrote a small server, executing just ServerSocket1->Open(); I wrote a small client : ClientSocket1->Address = "192.168.0.2"; ClientSocket1->Port = 1234; ClientSocket1->Open(); only i get a compilation error : [Linker Error] Unresolved external '__fastcall Scktcomp::TAbstractSocket::SetPortA(int)' referenced from BUILDERINO.OBJ. I looked for a patch that should solve it but the borland page that should contain it has gone offline. When i remove the line ClientSocket1->Port = 1234; i get an error : Project builderino.exe raised exception class ESocketError with message 'Asynchronous socket error 10049'. Process stopped. Use Step or Run to continue. I looked up error 10049 and it says that my address isn't set right. I use Builder 4 and run out of idears. Any help is appreciated.

I see that you do not care using capitals in your text, as if this was a chatroom; which it is not. Not using capitals makes your text difficult to read and is often confusing. But if you use dimensions you certainly need to take the dicipline to use capitals if there are. If it is a 700 MB file then please try that code first with 7 MB. Hans.

You don't show port in your code, but you mentioned 1024 which could be a bit small. See this link for a (large) list of registered ports. http://www.iana.org/assignments/port-numbers Pick something that is "unassigned" or that you know won't be a problem (like PlayStation2) Quote: TFileStream *file = new TFileStream("film.avi",fmCreate); try { ReadStream(Socket, file); } __finally { delete file; } Just wondering if "delete file" closes the file first. The docs only mention that it releases the handle. Perhaps FileClose( file->Handle); delete file; would fix a part of the problem?

Use only one. And you can connect to one ip-address only. Hans. Back to top Hans Galema Guest Posted: Wed Apr 27, 2005 3:30 pm    Post subject: Re: Socket problem setting port and connecting.
