Checking for Direct X

[Bruce]

I think this was Corey's coding below...

If I change the IF (%RegData% < 4.08.01.0000) to IF (%RegData% < 4.09.00.0902) it does nothing. What am I not changing correctly? Take a look.

Re: Checking for Direct X

IF (%RegData% < 4.09.0000.0902)
Try that. Seems like you were just short 2 numbers in the 3rd grouping.

Re: Checking for Direct X

NOPE! didn't work...
Thx for the reply.

Re: Checking for Direct X

Bruce, I see a couple of things that might be fouling things up here. First is the way that version math works in AMS. In my registry, it says I have version 4.09.00.0902 I don’t know if that is version 9b or not. I’m guessing that it’s not the newest version. Since your program is looking for version 4.09.0000.0902 I’m guessing that the version with the four zeros in the third grouping represents a newer version than what is on my machine (Not too surprising). If my assumptions are true, then AMS wouldn’t differentiate between four zeros and two zeros, when it did it’s little subtraction to compare versions. Any number if zeros minus any number of zeros is still zero, or zero change as far as AMS is concerned. If this is the case, I wonder if the version search can be combined with checking one of the other keys.

The other problem I see, is how the ‘if “ statements are nested, at the end of your script. It asks the first if, but doesn’t say “what” before it asks the second “if”.

Re: Checking for Direct X

Bruce,

This works for me.

// Setting DoesKeyExist to a default value so we can run a test on it.
%DoesKeyExist% = "NOTFOUND"
// This will search the registry to see if that key exists.
%DoesKeyExist% = Registry.DoesKeyExist ("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\DirectX ")
// Now we are going to check and see if the key was found or not. If found it will check the version...
IF (%DoesKeyExist% = "NOTFOUND")
%Result% = Dialog.MessageBox ("Title", "DirectX not installed", Ok, Question)
ELSE
// This will check for the version of DirectX
// directx 9.0b is 4.09.0000.0902
%RegData% = Registry.GetValueData ("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\DirectX ", "Version")
%Result% = Dialog.MessageBox ("Title", "%RegData%", Ok, Question)
// If it is less than 8.1 it will offer to upgrade
IF (%RegData% < 4.09.00.0902)
%Result% = Dialog.MessageBox ("Title", "You are running an older versi...", Yes|No, Question)
ELSE
%Result% = Dialog.MessageBox ("Title", "You are running the current ve...", Ok, Question)
END IF
