Yeah, we have no idea what else he's got to control, nor how he has to refer to them. The LED=n might work for him but it really depends on the complete list of items he needs to control and the verb and value options available for each of those. When he knows that, then he might be able structure a standard format command line if there are a lot of possibilities or, if not, simplify it to what you've said.
I've noticed that when I tried to set a string variable to the folderBrowserDialog.SelectedPath property it does not work. Can someone please explain why that is and is there a way around this? I don't want to have to keep writing folderBrowserDialog.SelectedPath every time I need to use it. Thanks in advance for your reply.

"Works on my machine".
Perhaps it'd help if you posted your code? The only way the property (which is a string, an can be assigned to a string-variable) is when the object that owns the property is not yet created. You'd get a refernce-exception.

If you can't read my code, try converting it here[^]
The "UnauthorizedAccessException was unhandled" exception was thrown and I get the error message "Access to the path 'C:\MyTestFile' is denied" when I run the code above. It works fine if I use folderBrowserDialog1.SelectedPath in place of myFolderPath.
You can't set string myFolderPath = folderBrowserDialog1.SelectedPath; until after the dialog has returned!
The string there before the call is not modified in place by the dialog.
It is replaced by the dialog. myFolderPath just has the wrong value.
Without seeing the result of the string concatentation you're using inside the parenthsis in the CreateText call, it's impossible to say for sure.
But, if the result is actually a valid path and you're trying to create a file in the root of C: on Vista or Win7, you'll get that error because normal Users cannot create files in the root of C:. You can make folder, not files.
On top of that, why are you calling ToString() on txtFileName.Text?? The .Text property returns a string, so the call to ToString() is a bit redundant.
Thank you everyone for responding. After reading your posts and reexamining my code, I realized that I did make two noob's mistakes. I've fixed the errors and everything works fine. I learned some valuable lessons today and that was the intention of the current project I'm working on. Thanks again for replying.
How can I check if my graph stays connected, after removing one or more edges from it?
I try to implement Christofides heuristik, and in some cases my code works (that is when the graph dosent disconnect under the process). Unlucky that is not the case for all the graphs.
I use Dijkstras to check if there is a route from my last node in the edge I am to remove, to other nodes. But, how du I see that "this" edge if removed is disconnecting the graph, so I can leave the edge and try the next one?
It would be easier to understand if I could post a picture of the problem. :(
