DataToSend Property

A string of data to be sent to the remote host. Write-only property.

Syntax

public void setDataToSend(byte [] dataToSend);

Remarks

This write-only property contains a string of data to be sent to the remote host. Assigning a string to this property makes the component send the string to the remote host. The Send method provides similar functionality.

The TCP/IP subsystem attempts to send the string assigned to this property as a complete message. If socket buffers are full, or the message cannot be delivered for any reason, an error is fired, and no portion of the message is sent. This is different from TCP where portions of the messages can be sent. The component sends either a complete message or nothing at all.

If you are sending data to the remote host faster than it can process it, or faster than the network's bandwidth allows, the outgoing queue might fill up. When this happens, this property fails with exception 10035: "[10035] Operation would block" (WSAEWOULDBLOCK). You can check this error, and then try to send the data again. .

This property is write-only and not available at design time.

Default Value

""
