This is an example of a Visual Studio 6.0 C++ which communicates with Ham Radio Deluxe using the DDE inter-process communications.

You will need the Microsoft SDK for some of the include files.

The actuall DDE code is in stddde.cpp and stddde.h which orginally came from Microsoft but have been edited.

 Click here to download the source code.

To run the demo:

1. Start Ham Radio Deluxe.
2. In the Demo press Connect to establish the DDE connection with HRD.
3. At the bottom of the window select a new mode and press Apply.
4. Similarly enter a new frequency in Hertz and press Apply.

Any questions - just contact HB9DRV.

As part of the new satellite tracking software development I needed to write some new DDE code, initially for the support of the NOVA protocol. To do this I developed simple projects for testing DDE logic in ASCII and UNICODE.

Two Visual Studio 6.0 C++ projects are available:

• DDE Server,
• DDE Client (DDE Monitor).

These are dialog projects which use MFC. If you have problems with DDE and C++ just contact HB9DRV.
