Get handle for dialog and RadioButton. Use EnableWindow() for enabling\disabling the control.

hwndDlg = CmdGetHwndDlg ( szDialogName );
hWndRadBtn = GetDlgItem( IntToHex(hwndDlg),nIDRadBtn);
EnableWindow( hWndRadBtn , FALSE);

IntToHex function:


function HWND IntToHex(value)
STRING sResult;
NUMBER h1, h2;
HWND handle ;

begin

sResult = "";
LOOP:
if ( value <= 16 ) then
sResult = HexEquivalent(value) + sResult;
while (StrLength(sResult)<8)
sResult = "0" + sResult;
endwhile;
sResult = "0x" + sResult;
StrToNumHex(handle,sResult);
return handle;
else
h1 = value/16;
h2 = value-(h1*16);
sResult = HexEquivalent(h2) + sResult;
value = value/16;
goto LOOP;
endif;

end;

function STRING HexEquivalent(value)
STRING szVal;
begin
switch (value)
case 0: szVal = "0";
case 1: szVal = "1";
case 2: szVal = "2";
case 3: szVal = "3";
case 4: szVal = "4";
case 5: szVal = "5";
case 6: szVal = "6";
case 7: szVal = "7";
case 8: szVal = "8";
case 9: szVal = "9";
case 10: szVal = "a";
case 11: szVal = "b";
case 12: szVal = "c";
case 13: szVal = "d";
case 14: szVal = "e";
case 15: szVal = "f";
default: szVal = "-";
endswitch;
return szVal;
end;

Hope it helps.

Thanks for help.
I wrote some scripts and fix the problem.

I use below line in my script to disable the radio button;

_WinSubEnableControl (hwndDlg, 1301, 0);
1301 - radio button identifier
0 - for disable
