Here we go... a working example for NX6 32bit written in C using Visual Studio 2005.
If you are looking for additional examples, I highly recommend searching for some in GTAC (if you have an account). They have a very large collection of simple examples from which you can learn. Perhaps you will find a similiar example to the one I have provided for the BlockStyler alternative.
If you found this example useful, I would appreciate it if you could mark this reply as "useful", thank you!
HOW TO USE:
1. The project is already built; you will have to edit the file "run.bat" and change the location of where NX6 is installed. The enviroment is necessary for NX to find the dialog file (radio_buttons.dlg).
2. Start "run.bat".
3. In NX, press Ctlr+U and select "ui_styler_radio_button.dll", then press OK to run the sample application.
The most important code is in the source file radio_buttons_template.c, particularily functions named *_cb.
I hope you are able to work off this example!
