Question
Importing ActiveX in Delphi 2005
Answer
Actually this problem can occur with OCX controls which have been
written using Visual Basic (VB).
You can solve this problem by doing the following in Delphi:
1. Select File, Open 2. Change file type to "Type Library" 3.
Select the ocx which you want to import. 4. After a long pause this
opens the Type Library Editor. Click on the name of the control at the top
of the tree in the left-hand window. 5. Click on "Flags" on the
right-hand panel so that there is a tick in 'Control'. 6. Now click on
the name of the control which appears part way down the tree (not the one
that begins with an underscore). Click on the check box that says "Can
Create" so that it is checked. 7. Select File, Save As from the Delphi
menu and save the newly created type library to C:\Program
Files\Borland\delphi (your version)\Imports 8. Save the file as your
ocx's name but with an extension of .tlb - for example myfabocx.tlb 9.
Select Project, Import Type Library 10. Import the myfabocx.tlb file
that you saved earlier. Don't forget to choose the name of the pallette
page it will appear in. 11. Make sure you say NO to overwriting the tlb
that already exists and make sure "create component wrapper" is ticked.
You should now see the OCX has been created on the component
pallette page that you selected in step 10. From that point on you can use
the control as if it was a VCL component.
If you distribute your application you need to put the OCX in the same
directory as your exe and then run "regsvr32 myfabocx.ocx" to register it
BEFORE your Delphi application can run.
