To many IF's. Is there a better way? - vb.net

Question

I have this code:
If CheckBox1.Checked = True Then
My.Computer.FileSystem.RenameFile("C:\Users\mario\Desktop\Dominio\1\Pc - S.txt", "Pc - S - A.txt")
'Sleep(2000) ' to sleep for 2 second
System.Threading.Thread.Sleep(2000)
My.Computer.FileSystem.RenameFile("C:\Users\mario\Desktop\Dominio\1\Pc - S - A.txt", "Pc - S.txt")
End If
If CheckBox2.Checked = True Then
My.Computer.FileSystem.RenameFile("C:\Users\mario\Desktop\Dominio\2\Pc - S.txt", "Pc - S - A.txt")
'Sleep(2000) ' to sleep for 2 second
My.Computer.FileSystem.RenameFile("C:\Users\mario\Desktop\Dominio\2\Pc - S - A.txt", "Pc - S.txt")
End If
And it continues with another 24 if's. I need them to change the name all at the same time and then wait two seconds and change it again all at the same time.Will i need to have 48(24+24) IF's?
Explanation:
Im creating a super simple way of shuting down the computers at my school. Here is my idea(hope you can understand it)
I put a program at every computer at school (in the regestry at the startup) that does the following:
(Atencion not really in a programing language)
for(1){
sleep 1000 // wait 1 sec
if.FILE.EXISTS(\\domain\folder1\shutdown.txt) then{
do: shutdown pc // if file exist it shutdowns the pc
}
}
So what this does is if there is a file in a certain directory in the domain, it shutsdown the pc.
Im doing this for 24 pcs, so i need to shutdown them individualy, therefor the many folders.
So i could simply rename the files by hand, but for 24 pcs that is a lot of work. So im developing a aplication that asks me what pcs i want to shutdown and then does:
1: Rename file.
2: Wait 2 or more seconds (so the computers in the network have time to verify if there is such file)
3: rename back the file so when the pc restarts it doesnt shutdown again.
Did you get what im trying to do? And yes there are more orthodox ways of doing this. but this is really simple, and this is more of a test than anything. (Later will be using more proper ways of doing this and do other options over the network)

Answer 1

Since the only difference is a single number in the filepath, why not do something like this?
var dict = new Dictionary<CheckBox, string>();
dict.Add(CheckBox1, "1");
dict.Add(CheckBox2, "2");
//etc
foreach (var kvp in dict)
{
if(kvp.Key.Checked == true)
{
My.Computer.FileSystem.RenameFile(String.Format("C:\Users\mario\Desktop\Dominio\{0}\Pc - S.txt", kvp.Value ), "Pc - S - A.txt")
}
}
We create a generic dictionary to store the association of the checkboxes to the string/number and then loop through the dictionary, checking the values. We use a format string (you could use string concatenation instead) to insert the string/number into the filepath string.
Note, this is in C#, as I'm not a VB programmer. The syntax will likely be slightly different.

Answer 2

Since your intention is to remotely shut down the PC's, why not actually shut them down from your code, rather than some hackish "create files then wait 2 seconds" approach?
Again, this is C# but the translation should be pretty straightforward:
var ComputerNames = new List<string>() {"Computer1", "Computer2", "Computer3"};
foreach(var pc in ComputerNames)
{
Process.Start("shutdown","-s -m \\\\" + pc);
}
