Invoking COM objects or .NET assemblies

Ignition
1

Hello.

Is it possible, through scripting, instantiate and invoke COM (Component Object Model) objects or (better) .NET assemblies?
If yes, does someone have some examples?

Of course: these are MS Windows specific platform features but our customer uses only MS.

Thanks in advance.

This won’t be possible through scripting, but you could probably develop a module that let you interact with the COM objects or .NET assemblies, assuming you can find a Java library that actually works and lets you do what you need to do.

Hello.

Thanks so much for your tip.
I’ve found one working solution, using the JACOB package; see http://sourceforge.net/projects/jacob-project/
After install it in the JRE folder, you can invoke COM objects directly inside the Ignition scripting.

Here an example.

[color=#FF00FF]import [/color]com.jacob.activeX.ActiveXComponent;
[color=#FF00FF]import [/color]com.jacob.com.Dispatch;
[color=#FF00FF]import [/color]com.jacob.com.LibraryLoader;
[color=#FF00FF]import [/color]com.jacob.com.Variant;

myObj = com.jacob.activeX.ActiveXComponent("[color=#0000FF]MyProgrId[/color]")

param1 = com.jacob.com.Variant("[color=#0000FF]MyParam1[/color]")
param2 = com.jacob.com.Variant("[color=#0000FF]MyParam2[/color]")
param3 = com.jacob.com.Variant("[color=#0000FF]MyParam3[/color]")

myObj.invoke("[color=#0000FF]MyMethod[/color]", [MyParam1, MyParam2, MyParam3])

Regards.
