View 2 RepliesTitle pretty much says it all. Does anyone know a way to to prevent a computer from entering a low/non-processing mode while the program is running? I don't care about monitor modes, screen-savers, hard-drive spindown, etc (in fact, I'd prefer to leave those alone; I like it that it shuts the monitor off after a time period).Basically, I have an industrial program that needs to continually monitor a PCI card it uses for IO; and this activity alone isn't enough to convince Windows not to go into Sleep mode. We normally just shut the power-save features off, but we had an incident where a technician forgot, a customer's machine went to Sleep after the end of the shift, the pumps stopped recirculating, yadda-yadda big mess.

"Write a program that allows users to vote on their favorite singer American Idol style. Your program should have the following features:
Your program should use a single listbox to display the names of the contestants and the number of votes for each contestant.
Use a class to hold the contestant�s first name, last name, and number of votes. The class should include a method to increment the contestant�s vote count by 1. Be sure to use property procedures for the first name, last name and number of votes properties.
Your program should read the names of contestants from an input file and display them in the listbox. You cannot make assumptions about how many contestants there will be in advance.
Your program should allow the user to sort the contestants by the number of votes they got. It should also allow the user to vote for any contestant any time by entering the last name of the contestant."So far this is the only code that I have... not sure why nothing is working.

I have a form where the user chooses a facility and then the list of patients for that facility are displayed in a data grid view. When I click to add a resident, the last name field on the data grid view is highlighted in blue below the last record that already exists.If I try to start typing without clicking in that cell, the facility changes - it looks like the control is still in the facility drop down box. How can I code it so that the user can just start typing in the data without having to physically click in the cell to start entering data?
