I am trying to add two radio buttons to a dialog box with values so that you can ONLY click the 'NEXT' button when one of the radios are checked.  I haven't been successful at all since i'm VERY new to this.  The following is all i have so far.
szMsg = "Select your Connection Type Below.";
szText1 = "HUMCMD.net Dial-up Access";
szText2 = "HUMCMD.net Broadband Access";
bvCheck1 = FALSE;
bvCheck2 = FALSE;
nResult = SdAskOptions(szTitle,szMsg,szText1,szText2,"",0);  
nValue = EXCLUSIVE;  
AskOptions (nValue, szMsg,szText1, bvCheck1,szText2, bvCheck2);

//CtrlSetState (SdAskOptions,bvCheck1,"Select your Connection Type Below.") ;

//if (CtrlSetState (SdAskOptions,bvCheck1, BUTTON_CHECKED) < 0)  then
//MessageBox ("First call to CtrlSetState failed.", SEVERE);  

if (bvCheck1 = 0 || bvCheck2 = 0)then
goto Dlg_SdAskOptions;


if (nResult = BACK) goto Dlg_SdRegisterUser;

I was trying to find a way to do this with Component Trees, as well.  I'd like Next button greyed-out if no components are check in (say) the Custom Setup tree.

All I do now is loop until at least one component is checked, but this isn't very elegant.

Is there a general-purpose solution to this?

I third this.  We're working with the same issues.  Need to grey out the next button if the option is not selected in the Options dlg and also, disable it on custom install if nothing is checked.  It would also be nice to be able to grey it out on the modify screen if the user chooses to remove the app.

Anyone have an answer or is this something we should approach InstallShield with, since so many of us are facing the same issues?

You would have to do this inside the script that drives the dialog box (message handler). Unfortunately in IS6 these scripts are not available in source code. They were in IS5, so for dialogs that exist in IS5 in a similar way you may be able to use these.
The alternatives are either to create a custom dialog from scratch, or use the InstallDialogue tool from http://moonsea.com

Is there a way to disable a control in a custom scripted-dialog without re-initializing the dialog? I've found that EnableWindow(hwndControl, FALSE) doesn't immediately work. If I close the dialog, then re-initialize it, then the control will show up disabled.

Unfortunately, this screws up the tab order. Is there any way around this?
