How to use a custom DLL with common / reusable functions within scripting

[Frits]

To create a common set of functions and reuse them across graphic forms in the SmartUI:

1. From within Visual Studio, create a new project and choose class library
2. Add the functions you require, if you need to access any of the namespaces that you normally have available in scripting remember to add the references to your class library as well.
3. Add the compiled DLL as a reference in your script.

More detailed explanation from Visual Studio:

1. Create a class library project (this could be C#, VB.Net or any other .NET language you choose for your class library, the example here is C#):

2. If you would like to use existing SmartUI references, remember to add them:

Once you have created your DLL, just add it as a reference from within your script.

If you would like to use a common set of functions throughout multiple graphic forms and you would like to use the same instance of a class, consider using the singleton design pattern so that the same instance of the class is returned for all graphic forms requesting it:

public class MyUtilitiesClass
{
	private static MyUtilitiesClass _instance;
	public MyUtilitiesClass GetInstance()
	{
		if (_instance == null)
		{
			_instance = new MyUtilitiesClass();
		}
		return _instance;
	}

//put the rest of your functions and common variables here

}

Now add this DLL as a reference in your graphic form scripts and access the same instance from different graphic forms.

This can also be used to set Global User Interface variables. In this way you can manage and track user interaction by setting variables as the user interacts with the system.

Dear Frits and other forum leaders,

I’m new to MAPS.
I need very much to use reusable class libraries (dll).
I’ve used reusable class libraries in C# projects before.
But with MAPS I cannot use as you explained here.

I’ve created a class library in Visual Studio (C# .NET 4.0)
Referenced the created dll to the MAPS script (Grapghic Form script).
But when I running the form it does nothing.
It doesn’t even catching exceptions.

Please could you please guide a little more.
Looking for your reply

Put Your dll under C:\Program Files (x86)\Adroit Technologies\MAPS and try running the graphic form under MAPS Designer - if there is something missing, You will see the error in output window.
