OLE Control Container Support in Visual C++ and MFC

WINDOWS        | WINDOWS NT

The information in this article applies to:

• Microsoft Visual C++ for Windows, versions 1.5, 1.51, 1.52
• Microsoft Visual C++, 32-bit Edition, versions 2.0, 2.1, 2.2

SUMMARY

The Microsoft Foundation Classes included with the versions of Visual C++ listed at the beginning of this article do not provide any support for creating OLE control containers.

MORE INFORMATION

The OLE Control Development Kit (CDK) provides the ability to create OLE controls which can be used in OLE control containers such as Microsoft Visual FoxPro version 3.0 and Microsoft Access version 2.0. However, current versions of MFC and Visual C++ do not provide any support for creating OLE control containers.

The next major version of Visual C++, currently planned for release in the fall of 1995, will provide support for creating OLE control containers.

REFERENCES

Here are sources of information regarding creating an OLE control container:

• "Notes on Implementing an OLE Control Container"

  This article by Kraig Brockschmidt can be found on the Microsoft Developer Network CD (MSDN). It discusses the OLE control container architecture and provides sample code that illustrates how to implement an OLE control container.

• "Implementing OLE Control Containers with MFC and the OLE Control Developer's Kit"

  This article by Mike Blaszczak can be found on the MSDN CD and in the April 1995 issue of the "Microsoft Systems Journal." It discusses different types of OLE control container support and provides sample code for an OLE control container.

• "CONTROLS: Demonstrates How to Test OLE Controls"

  This article can be found on the MSDN CD and in the February 1995 issue of the Microsoft Systems Journal. It includes a sample application that implements a version of the MFC DRAWCLI sample that has been modified to provide OLE control containment.

Microsoft Developer Support does not currently provide any support for the creation or implementation of OLE control containers. Because the next major version of Visual C++ will provide a fully supported OLE control container implementation, Microsoft recommends that developers wait for this release unless they have an immediate need for OLE control containment.
