DataToSend Property

A string of data to be sent over the connected pipe.

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_PIPECLIENT_DATATOSEND 4


IPWORKSIPC_EXTERNAL int IPWORKSIPC_CALL IPWorksIPC_PipeClient_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 server. The Send method provides similar functionality.

When Timeout is set to 0 the class will behave asynchronously. If you are sending data to the receiving process faster than it can process it, the outgoing queue might fill up. When this happens, the class 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.
