Résumé: A step by step guide to importing a BCL Winforms component into a VCL package for use in a VCL application
by Tim Jarvis and John Kaster
Delphi 8 installs a utility into the Delphi 8 program group (available from
the start button) called "WinForms Control Import Wizard". You can use this
utility to wrap standard .NET controls for using in a VCL application. This
is the menu displayed in the Delphi program group:
Select the last menu option and you should see this dialog:
This wizard allows you to navigate to an assembly that contains an FCL
component (for example a winforms DataGrid contained in
After navigating to the assembly, you will get a list of all the controls
contained in the assembly. Select the one you want.
You can also use the wizard to specify what parts of the control to wrap.
For our example, the defaults are what we want. We can then specify where the
generated files should be written, and what the package assembly should be
You are prompted to confirm the overwrite of existing files.
When you select next, the wrapper unit will be created and the package
project files will be created.
Note: The package will not be compiled. You will need to load the package project
into Delphi 8 and compile it.
Click finish to close the Wizard.
Next, we'll load the package project into the IDE.
The project manager displays it.
Compile the project, you will now have a VCL package assembly that contains a
wrapper around the FCL component.
Now we need to install the package so that we can use it in a VCL
application. Select "Installed .NET components..." from the component menu,
or select it by right-mouse clicking on the component palette, and you should
see the following dialog. Click on the .NET VCL components tab.
Note: The first time you select this dialog, it will take a while to compose the
list of all assemblies on your machine, and the components that are available
Add and navigate to the package assembly dll
The package and component is now installed and ready to be used.
We should now see this component in our palette and can use this in our VCL
