#!F-adobe-helvetica-medium-r-normal--18* #!N #!CSeaGreen #!N #!Rall1147 Sending Messages to the Server #!N #!EC #!N #!N The function DXLSend (see #!Lmsgrtns,dxall1150 h Messaging Routines #!EL ) sends specific messages directly to the server. In general, one needs to be sure that the server will either handle the message properly or ignore it. The user interface will ignore most unrecognized messages, while the executive will accept most legal scripting-language commands. #!Lsetvars,dxall1154 h Setting Variables #!EL discusses how an application program can set the value of variables in a visual program. #!N #!N Other functions may also result in messages to the server. For example, DXLStartDX initiates the connection to the server and manages all the messaging associated with establishing the connection to Data Explorer. #!N #!N When a function call results in sending a message to the server, DXLink can either synchronize with the server to ensure that the message has been accepted or it can return without receiving an acknowledgment. By default, DXLink is configured to use the latter (asynchronous) method. DXLSetSynchronous sets the synchronization method to be used. DXLSync allows synchronization at specified points in an application that does not use synchronous mode. #!N #!N #!N #!F-adobe-times-medium-i-normal--18* Next Topic #!EF #!N #!N #!Lrcvmsg,dxall1149 h Receiving Messages from the Server #!EL #!N #!F-adobe-times-medium-i-normal--18* #!N
