1 Introduction
Limnor Performer Import Wizard is a tool to convert ActiveX controls and .Net classes into Limnor
Performers. Thus you can use those software components in your Limnor applications.
The properties, methods and events of an ActiveX control or a .NET class become the properties,
methods and events of the Limnor Performer generated. The Wizard lets you choose which properties,
methods and events to be generated.
It should be pointed out that codeless programming as the new generation of software engineering it is
fundamentally different than current software engineering based on coding. ActiveX controls and
.NET classes are designed for coding. Therefore the designs of ActiveX controls and .NET classes are,
in most cases, not best for codeless programming. This Wizard just does a direct converting and
cannot re-design them for best codeless usages. The Wizard will produce source code of the Limnor
Performer generated, and you may hand-craft on the source code to create Performers best fit for
codeless programming and your needs.
2 Choose Source Type
Click “Start” button to start the Wizard:

Limnor Performer Wizard
It allows you to choose one of 3 source types to start:

Limnor Performer Wizard
.Net Class. This option lets you select a .NET DLL and select a class from the DLL to be
converted into a Limnor Performer.
ActiveX control. This option lets you select an ActiveX control. The wizard will convert it to
a Limnor Performer.
Compile C# code. This option lets you compile a C# source code file into a DLL file. You
may modify the source code generated from the other options and use this option to compile
your code into DLL files.
3 Convert .NET Classes
When you select “Create a new Performer from a .NET class” and click Next, it allows you to specify
a DLL file containing the class you want to convert. You can select a DLL file made by you or some
one else. Let’s use a DLL from Microsoft .NET Framework to do the demo. You can find all DLL for
Microsoft .NET Framework in a folder named “Microsoft.Net\Framework\v<version number>” under
Windows folder:

Suppose we want to convert the Button class into a Limnor Performer. The Button class is in
System.Windows.Forms.DLL. Click button “Select a DLL file”, select System.Windows.Forms.DLL:
All public classes contained in the DLL file will be listed for your choice. There can be too many
classes and not easy to find the one you want. If the class to be converted is a screen element (derived
from Control class) then you may check the option “Show screen elements only”. With this option
checked, non-screen-elements will be excluded from the list, making it easier to locate the class you
want.
In our case, we want to locate and select the Button class, and click Next:

Limnor Performer Wizard
All properties of the selected class will be listed for you to make selections. Selected properties will
become the properties for the new Limnor Performer:
All rights reserved by Longflow Enterprises Ltd.
5
Limnor Performer Wizard
All events of the selected class will be listed for you to make selections. Selected events will become
the events for the new Limnor Performer:
All rights reserved by Longflow Enterprises Ltd.
6
Limnor Performer Wizard
All methods of the selected class will be listed for you to make selections. Selected methods will
become the methods for the new Limnor Performer:
All rights reserved by Longflow Enterprises Ltd.

Limnor Performer Wizard
After selecting properties, events and methods, click Next. A C# source code file is generated. The
source code is for the new Limnor Performer:
All rights reserved by Longflow Enterprises Ltd.
8
Limnor Performer Wizard
Clicking Next will compile the source code into a DLL. Once it is in DLL your Limnor applications
can use it.
Before compiling it, if you know more DLL files are needed for the compilation, you may use “Add”
button to add such DLL files into “Support DLL files” list.
To generate debug information during compilation, check the box “Debug”.
You may modify the source code before compilations. Click button “Edit”, the source code is
displayed for editing:

Limnor Performer Wizard
As you can see, the source code editor is a simple one. It does not have color coding as a professional
source code editor. And it does not have intelli-sense as Visual Studio does.
When you are ready to compile the source code, click Next. If there are compilation errors then those
errors will be displayed. You may edit the code according to the error messages, and re-do the
compiling by clicking the Next button again.
If compilation succeeds then you may click “Test load” button to test the newly compiled DLL:
All rights reserved by Longflow Enterprises Ltd.
10
Limnor Performer Wizard
If the testing does not find any problems then you can see the last
line of the message is “No errors found”. We are done.
If the testing finds problems then you may click “Save to file” button
to save the test results to a text file for later references. You may
modify the source code according to the test results and recompile it.
Before you can re-compile the source code, you need to close this
wizard program and re-run it because the testing will cause the
operating system to lock the DLL file.
With the new DLL compiled and testing being OK, we will see the new
Limnor Performer in the toolbox under “Others” category:

4 Convert ActiveX Controls
When you select “Create a new Performer from an ActiveX control” and click Next, it allows you to
search for ActiveX controls:
All rights reserved by Longflow Enterprises Ltd.
12
Limnor Performer Wizard
Click button “Select from all COM objects”. It will start searching your computer for all COM
objects:
You may then select the ActiveX control you want from the list:
All rights reserved by Longflow Enterprises Ltd.
13
Limnor Performer Wizard
You can see the DLL file for the selected ActiveX control is also displayed.
If you know the DLL/OCX for the ActiveX control then you do not need to search for all COM
objects. You may click button “Select a DLL or OCX file” to pick that file.
When you select a COM file, all COM objects contained in the file will be displayed. Make sure the
ActiveX control you want to convert is in the list.

14
Limnor Performer Wizard
Click Next. A .NET DLL file will be created. It wraps all COM objects to .Net classes:
All rights reserved by Longflow Enterprises Ltd.
15
Limnor Performer Wizard
At this stage it is the same as we have selected option of “Create a new Performer from a .NET class”.
The .NET DLL file we used is the newly created DLL file for wrapping the ActiveX control. In our
example here, it is AxInterop.OWC11.DLL. The only difference from the option of “Create a new
Performer from a .NET class” is that the button “Select a DLL file” is disabled, because we do not
need to select a .NET DLL.
The next operations are exactly the same as we described for option of “Create a new Performer from
a .NET class”. Only that for ActiveX controls, you may see some properties cannot be used. When we
get through all the steps and click “Test load” button, it will show the properties failed to load:

16
Limnor Performer Wizard
You may click “Save to file” button to save the results to a text file for references. From the text file
we can see such errors:
We need to close this wizard program to release the DLL we generated. We re-start the wizard
program, and re-do it. At the step of selecting properties, we may uncheck those properties which
cause problems:

Now this time no errors are found:

Limnor Performer Wizard
When you are doing a converting and you do need those properties causing errors, please contact us at
[email protected] We may hand-craft it to put those properties back.
Now we may start using the new Performer in our applications:

5 Compile C# code
When you choose option “Compile C# code”, the Wizard jumps to the step of before compiling and
enables the “File” button:
All rights reserved by Longflow Enterprises Ltd.
20
Limnor Performer Wizard
Click “File” button to specify the source code file to be compiled. If your source code uses classes
from other .NET DLLs then you need to add the DLL files to the “Support DLL files” list:
All rights reserved by Longflow Enterprises Ltd.
21
Limnor Performer Wizard
Click Next. The source code will be compiled into a DLL file.
