Change System Date/Time with C#

[session]

How to?

[Holiday]

Just start the extern process cmd.exe with the time argument, i.e.
String arg = @"/C \"time hh:min:sec\"";

Similar with date:
extern process : cmd.exe
arg =@ "/C \"data dd-mm-[yy]yy\"";

Hope this helps

can you please explain a lil bit more???

[pareshgh]

it is better way to use
P/Invoke functions using Win32 API.

define this structure in your form's main class
------------------------ [StructLayout(LayoutKind.Sequential)]
public struct SYSTEMTIME
{
public short wYear;
public short wMonth;
public short wDayOfWeek;
public short wDay;
public short wHour;
public short wMinute;
public short wSecond;
public short wMilliseconds;
}

[DllImport("kernel32.dll", SetLastError=true)]
public static extern bool SetSystemTime( [In] ref SYSTEMTIME st );


----------------------


now somewhere you can test following

SYSTEMTIME st = new SYSTEMTIME();
st.wYear = 2003; // must be short
st.wMonth = 5;
st.wDay = 22;
st.wHour = 0;
st.wMinute = 0;
st.wSecond = 0;

SetSystemTime(ref st); // invoke this method.

-hope this helps,

The way parshgh proposed is the more sophisticated. You should use this way.
Just for satisfying your request:

args as in the first post!

string command= "cmd";
string args = string.Format("/C \"{0}\"",argument.Trim());

System.Diagnostics.ProcessStartInfo psi =
new System.Diagnostics.ProcessStartInfo(command,args);

psi.UseShellExecute = false;
System.Diagnostics.Process proc = null;
proc = System.Diagnostics.Process.Start(psi);

Hi
I want to use your code in my project too. but I don't know where I have to write these parts
would you please give me a single example of using these instructions in C#.NET 2005 ? I really need this so emergency
I'm looking forward your respond
thanks

[roza_gh]

what's the meaning of this error?????????????

Error 2 The type or namespace name 'StructLayout' could not be found (are you missing a using directive or an assembly reference?) F:\Documents and Settings\admin\My Documents\Visual Studio 2005\Projects\changesystemtime\changesystemtime\Form1.cs 13 12 changesystemtime

[hspc]

Add this line at the top of your code where you use StructLayout attribute.

using System.Runtime.InteropServices;

[nidostyle]

extern process :cmd.exe arg
arg=@ "/C \"data dd-mm-[yy]yy\"";

this is what language code i cant run it in C# can you write the whole function
instead of writing snapet

process: cmd .exe

does not support by Process class
argumets also

plz tell breafly

plz explan it.
