attempting to compare a variable with the contents of an array

[Lucian Cain]

I am attempting to compare the variable "ResultOS" with the contents of the array/table "PossiableOS.Valid".
any ideas?

ResultOS = System.GetOSName();
PossiableOS = {};
PossiableOS.Valid = {"Windows 98 SE", "Windows 2000", "Windows XP"};
PossiableOS.Invalid = {"Windows 95", "Windows 98", "Windows ME", "Windows NT 3", "Windows NT 4", "Windows Server 2003"};

if ResultOS == PossiableOS.Valid{} then

do this

else

do this

end

Hello,

Something like this may work for you:

Valid_OS = {"Windows 98 SE", "Windows 2000", "Windows XP"};
sSystemOS = System.GetOSName();

for nIndex, sOS in Valid_OS do
	if (sSystemOS == sOS) then
		bValidOS = true;
		break;
	end
end

if bValidOS then
	-- The OS is valid
	Dialog.Message("", "Valid OS");
else
	-- The OS is invalid
	Dialog.Message("", "Invalid OS");
end

sorry in advance for the lengthy post...

MGT wanted it to look for the reverse Desmond, thanks for your help. (GRUMBLE, GRUMBLE) I am still having a slight problem. Maybe it is just me. I do not understand how you went from the table PossiableOS.Invalid to boolean bPossiableOS.Invalid:

for nIndex, sOS in PossiableOS.Invalid do
if (sResultOS == sOS) then
bPossiableOS.Invalid = true;
break;
end
end
if bPossiableOS.Invalid then

Hello,

bValidOS was set in this block of my example, and only if the user's OS was on your allowed list:

for nIndex, sOS in Valid_OS do
	if (sSystemOS == sOS) then
		bValidOS = true;
		break;
	end
end

I'm simply setting a variable to true so I can check it later.

Does that answer your question?

yes, thanks
