Davi,

Are you talking about DirectIO now?
Any errors you are getting?
Did you include all the DirectIO dependencies?
Did you try your application and DirectIO under XP Pro?

If you can't get it working with DirectIO, switch to WinIO as Stuart suggested. It is a great libary.

PS. What are trying to accomplish with your app? Is it somehow related to watchdog timers?
 
Dear KM,

Yes, I am talking with DirectIO.
I thinks I had include all the DirectIO dependencies and it is works fine in
WinXP Pro.
I will try WinIO in next step.

PS : As you say, I want use the app to control watchdog timers.
 
Davi,

It would be hard to help you to debug the issue if you don't elaborate on what errors you are gettings.

Please verify that the Direct-IO package got installed properly (check Device Manager and SetupAPI.log).
Or properly componentize the package.You can install it on XP Pro, capture all the files and registry entries with tools like
RegSnap and InCtrl5.

For the debugging purposes you can also use Regmon and FileMon (www.sysinternals.com).
