The Visual Basic 3.0 FAQ covering the CDK may contain additional
information regarding a portion of these questions. This FAQ is in the
process of being completed. More frequently asked questions will be added
to this article by the end of January 1996.
- Q. How do I create an OLE control?
A. Visual C++ 4.0 comes with the OLE CDK, which will allow you to create
an OLE control. It also comes with the Control Migration Pack, which
will help in transforming a VBX control written in C into an OLE
control.
For additional information, please see the following article(s) in
the Microsoft Knowledge Base:
Q113895 Intro to Microsoft OLE Custom Control Architecture & Tools
This article discusses OLE controls and their future within Visual
Basic and Windows.
- Q. How do I create a 16-bit OCX? VC++ 4.0 is 32-bit only, right?
A. Yes, Visual C++ 4.0 is 32-bit only. But it also ships with Visual C++
1.52, which includes some bug fixes to 1.5 (our 16-bit compiler), and
support for the OLE Control Development Kit. It also has a mechanism
(the Control Migration Pack) for migrating the source code to a VBX
you've created into an OCX via the AppWizard with relatively little
effort.
- Q. How do I create a 32-bit VBX?
A. You can't. Ever. You can, however, create both 16-bit and 32-bit
versions of OLE controls (OCXs). Visual C++ 4.0 supports this with
the OLE Control Development Kit.
- Q. How do I create my own custom controls?
A. Visual Basic 3.0 Professional Edition ships with the Control
Development Kit (CDK), which allows you to create a custom control,
that is, a VBX. The VBX Control Development Kit does not ship with
Visual Basic 4.0. However, to use the CDK you also need a C compiler
that can create Windows DLLs. Visual C++ comes with a project option
for building a VBX. You might find the following references useful
when creating a Custom Control (VBX):
