First thanks to DaveTips, raochetan, gxlzlu and Zyrenthian, but I feel like I'm talking to the planet "MorBok" with these "handles". I now have an application with a edit box that takes a CString. I convert this to an hex int and send it out a port. I also added Radio Buttons so the user could switch between entering decimal or hex. Since my code defaults to hex, I'd like to have the app come up with the "Hex" Radio Button highlighted. Any suggestions?? thanks in advance
