A string of data to be sent to the remote host.

Syntax

ANSI (Cross Platform)
int SetDataToSend(const char* lpDataToSend, int lenDataToSend);

Unicode (Windows)
INT SetDataToSend(LPCSTR lpDataToSend, INT lenDataToSend);
@property (nonatomic,readwrite,assign,getter=dataToSend,setter=setDataToSend:) NSString* dataToSend;
- (NSString*)dataToSend;
- (void)setDataToSend:(NSString*)newDataToSend;

@property (nonatomic,readwrite,assign,getter=dataToSendB,setter=setDataToSendB:) NSData* dataToSendB; - (NSData*)dataToSendB; - (void)setDataToSendB:(NSData*)newDataToSend;
#define PID_IPPORT_DATATOSEND 4


IPWORKS_EXTERNAL int IPWORKS_CALL IPWorks_IPPort_Set(void *lpObj, int propid, int arridx, const void *val, int cbVal);

Default Value

""

Remarks

Assigning a string to this property makes the class send the string to the remote host. The Send method provides similar functionality.

When Timeout is set to 0 the class will behave asynchronously. 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, DataToSend fails with error 10035: "[10035] Operation would block" (WSAEWOULDBLOCK). You can check this error, and then try to send the data again. The BytesSent property shows how many bytes were sent (if any). If 0 bytes were sent, then you can wait for the ReadyToSend event before attempting to send data again. (However, please note that ReadyToSend is not fired when part of the data is successfully sent).

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