Hello, how i can replace the missed functions ReadBuffer and WriteBuffer in TIdTCPConnection? --------------------------------------------- Thomas Wegner Cabrio Meter - The Weather Plugin for Trillian http://trillian.wegner24.de/cabriometer Back to top Remy Lebeau (TeamB) Guest Posted: Fri Nov 12, 2004 6:24 pm    Post subject: Re: Indy 10 ReadBuffer, WriteBuffer, where?

Use the ReadBytes() and Write(TIdBytes) methods of TIdIOHandler instead, respectively.

It would help if you could show what you are actually trying to send/read in the first place. In general, Indy 10 does not support operations are raw memory anymore. This is required in order to support DotNet. TIdBytes is just an array of bytes. When calling Write(), you have to allocate a TIdBytes and put your raw data into it. When calling ReadBytes(), a TIdBytes is returned containing the data, so just extract your data from it as needed. For example: // writing... var Buf: TIdBytes; begin //... Buf := Idglobal.RawToBytes(YourRawData, SizeOfYourRawData); ...Write(Buf); //... end; // reading... var Buf: TIdBytes; begin //... ...ReadBytes(Buf, NumberOfBytes); Idglobal.BytesToRaw(Buf, YourRawData, NumberOfBytes); //... end; Make sure to download the latest snapshot of Indy 10, I just added the BytesToRaw() function to Indy 10 a few minutes ago.

I changed following now (for others): Indy9: Context.Connection.ReadBuffer(buffer^, size); Indy10: Buf : TIdBytes; .... Context.Connection.IOHandler.ReadBytes(Buf, size); BytesToRaw(Buf, buffer^, size); and Indy9: Context.Connection.WriteBuffer(Buffer, Count); Indy10: Buf : TIdBytes; .... Buf := RawToBytes(Buffer, Count); Context.Connection.IOHandler.Write(Buf); --------------------------------------------- Thomas Wegner Cabrio Meter - The Weather Plugin for Trillian http://trillian.wegner24.de/cabriometer "Remy Lebeau (TeamB)" <no.spam (AT) no (DOT) spam.com> schrieb im Newsbeitrag news:419524f5$1 (AT) newsgroups (DOT) borland.com...
