Aximp is a tool which is shipped with .Net Framework where Ax stands for Active X and imp for importer. This tool is used to convert Active X control to a windows form control. The .NET equivalent of ActiveX controls are Windows Forms controls. This tool actually creates a wrapper around the Active X control so that it can used from .NET (i.e. managed code). It basically creates an Active X interop assembly.
This wrapper class is derived from System.Windows.Forms.AxHost. This wrapper control contains an instance of the underlying ActiveX control and has access to all its properties and events. To host any Active X control on a Win Form it is necessary to extend it from Axhost class.
There are several ways by which you can use Active X components in the .NET. One of the ways would be adding the active component to your toolbox directly as follows :-
1. Right click on the tool box .
2. Select customize tool box.
3. Select the COM component.
4. Drag and drop the Active X control on your form.
You will see that .NET Studio has generated an interop assembly (solution explorer) for the selected active X control. Now you can use this control seamlessly as you would have used any other .NET component.
We will create this same interop using Aximp.exe.
Go to the visual studio command prompt and type aximp.exe /h. This will display all the options available with Active X importer.
Setting environment for using Microsoft Visual Studio 2008 x86 tools. D:\Program Files\Microsoft Visual Studio 9.0\VC>aximp.exe/h
Microsoft (R) .NET ActiveX Control to Windows Forms Assembly Generator
[Microsoft .Net Framework, Version 2.0.50727.1434]
Copyright (c) Microsoft Corporation. All rights reserved.
Generates a Windows Forms Control that wraps ActiveX controls defined in the giv en OcxName.
Usage:
AxImp OcxName [Options]
Options:
/out:FileName File name of assembly to be produced
/publickey:FileName File containing strong name public key
/keyfile:FileName File containing strong name key pair
/keycontainer:FileName Key container holding strong name key pair
/delaysign Force strong name delay signing
Used with /keyfile, /keycontainer or /publickey
/source Generate C# source code for Windows Forms wrapper /rcw:FileName Assembly to use for Runtime Callable Wrapper rather than generating new one.
Multiple instances may be specified. Current directo
ry is used for relative paths. /nologo Prevents AxImp from displaying logo
/silent Prevents AxImp from displaying success message
/verbose Displays extra information
/? or /help Display this usage message
To create a interop for an active component you need to type the name of the component ( make sure you in the same directory as your Active X component is ... else type the whole path).
e.g. C:\WINNT\system32>aximp comdlg32.ocx (This is VB's common dialog Active X control)
This will generate interop assemblies for the selected active X control as shown below.
Generated Assembly: C:\WINNT\system32\MSComDlg.dll
Generated Assembly: C:\WINNT\system32\AxMSComDlg.dll
You will notice that there are 2 assemblies that are generated, but one prefixed with Ax. The second one that is the one which is prefixed with Ax is the Active X Assembly and the first one is the Interop assembly.
The Interop assembly made by tlbimp is same as the one made by aximp.
Open the AxMSComDlg.dll with ildasm and notice that it extends System.Windows.Forms.Axhost class which is required to host an Active X control in a winform.
