> AFAIK, it is limited with packet length. ReceiveStr will return at most what can fit into winsock receive buffer which default to 8KB if memory serve me well. But if your program is responsive, you'll likely never receive more than the largest packet size which is 1514 bytes on Ethernet. >> I mean, are there any limitations or can I send a complete (maybe >> acsii-coded) picture (~200kByte) in a String? Sending is totally independent of receiving ! TCP has no datagram boundaries preserved. TWSocket will accept any size in SendStr. No problem to load your image into a single string and send it in a single call to SendStr. This is a bad idea, but ot will work. This doesn't mean the receiver will receive in a single OnDataAvailable ! Please read "TCP/UDP primer" available from "support" page at http://www.overbyte.be for more explanation. btw: To send a small image, you'd better load it into an array of bytes and send it in a single call. For larger images, it is better to read the image file by chunck (for example 4KB) and send each chunk individually. You send the next chunk from the OnDataSent event. This way, you have never more than 4KB in memory and will able to send multi-megabytes or gygabytes of data without "using" too much RAM. Contribute to the SSL Effort.
