My bad, I meant to say Ticks are 100 nanosecond units.
TickCount becomes inaccurate (without conditional calculation) if the system is up for more than 24,9 days
To get system uptime I used this
DateTime Utime = new DateTime(1970, 1, 1).AddSeconds(t);
string uptime = String.Empty;
uptime += (Environment.TickCount / 86400000).ToString() + "d";
uptime += (Environment.TickCount / 3600000 % 24) + "h";
uptime += (Environment.TickCount / 120000 % 60) + "m";
uptime += (Environment.TickCount / 1000 % 60) + "s";

This bit of code will give you the system uptime regardless of how long the system has been running:
TimeSpan uptime = TimeSpan.Zero;
using (var ut = new PerformanceCounter("System", "System Up Time")) {
ut.NextValue();
uptime = TimeSpan.FromSeconds (ut.NextValue());

The Windows "System" process has a StartTime value of 01/01/1601 00:00:00. It is what it is and there is nothing you can do to transform the value into the actual start time of the process.
You have to accept that Windows is not giving you the start time and assume that 01/01/1601 means "not available". If you want to assign a hypothetical start time corresponding to computer's boot time then do so, but be clear in your own mind that the calculation you do to get that has nothing to do with January 1, 1601.

Hi Alan,
I am aware of the unix epoch time value for Window's "System" process starttime but I have to disagree that it is 01/01/1601, that is just what it reports.
As I posted in my original question, if you do this
string stime = String.Empty;
stime += (Environment.TickCount / 86400000).ToString() + "d";
stime += (Environment.TickCount / 3600000 % 24) + "h";
stime += (Environment.TickCount / 120000 % 60) + "m";
stime += (Environment.TickCount / 1000 % 60) + "s";
you can get the amount of time that the process has been running. From that, a better coder than I could deduce the starttime by somehow converting the resultant stime string to a datetime then subtracting it from datetime.now.

1) Unix time's epoch is 1/1/1970
2) 01/01/1601 is the epoch for Windows FileTime which is used by the operating system to report process start times. See for example the documentation for the win32 function GetProcessTimes[^].
3) I stand by my assertion that a reported process start time of 01/01/1601 is Windows way of telling you that it's not telling you.
4) Has this whole thread been about this?
private void Boot() {
DateTime boot = DateTime.Now - TimeSpan.FromMilliseconds(Environment.TickCount);
Console.WriteLine("System started at {0}", boot);
}
Alan.

Hi,
4) No, I already have a way to get the system uptime, I would like to get a full listing of all processes and as much information as I can get for each process.
Will get back to you on the others.

Well isn't that strange.
Okay, Environment.TickCount it is, but that resets every 232 ms, so that's not really useful either.

Ravi's answer gives the proper way to do it using a performance counter, thus avoiding the Int32.MaxValue problem.
Also see GetTickCount[^] for some useful info.

This is a very broad question that cannot be easily answered in a forum like this. Take a look at the articles[^] section, or try some Google searches to get some ideas and sample code.

You just did.
Why is common sense not common?

You did. The problem is no the lack of "experts" seeing your question.
The problem is that your question is so broad and requires an answer so large that it won't fit in a few forum posts.
The quality of the answer you get is directly dictated by the quality of your question.
BTW, using a downloader on sites like YouTube, or pretty much any other, is a violation of their terms of service. You are basically stealing their content and can be arrested for doing so.

Take out the single quotes from your query string.
make it
SqlCommand cmd = new SqlCommand("select * from " + comboBox1.SelectedItem.ToString(), con);
The difficult we do right away...
...the impossible takes slightly longer.
