This command-line executable provides an easy way to execute the templates of the SendCommand function from different environments

 

SendCommand function allows operations to be performed, using a standard template in XML and JSON format, synchronously or asynchronously.

 

For example, lksendcommand can be used from a Windows .bat file or from a BASIC Program, to access data from a remote MV database.

 

On Windows the syntax is: lksendcommand.exe [options]

 

On Linux and macOS the syntax is ./lksendcommand [options]

In the demo /lksendcommand folder there are script examples and command files that execute them so you can try some Linkar functions.

 

In Windows, see script demo_lksendcommand.cmd, which must be modified with local credentials before execution.

 

@ECHO OFF

 

SET host=127.0.0.1

SET entrypoint=E1

SET epport=11500

SET user=admin

SET pass=admin

SET freetext="From lksendcommand"

SET encoding=""

 

lksendcommand.exe /F:XML/New-None.xml /U:%user% /W:%pass% /H:%host% /P:%epport% /E:%entrypoint% /T:%freetext% /O:NewResponse.xml /M:XML /C:%encoding% /R

...

 

In Linux and macOS versions, it is called demo_lksendcommand.sh:

 

#!/bin/sh

 

host=127.0.0.1

entrypoint=E1

epport=11500

user=admin

pass=admin

freetext="From lksendcommand"

encoding=""

 

mono lksendcommand.exe /F:XML/New-None.xml /U:$user /W:$pass /H:$host /P:$epport /E:$entrypoint /T:"$freetext" /O:NewResponse.xml /M:XML /C:$encoding /R

...

In the MV components there is a command called LK.DEMO.SENDCOMMAND that executes operations against any database connected to Linkar from BASIC.
