As already stated, a Windows Service is designed to run in the background without a UI and is best suited for tasks that do not need user interaction or even a user session. If at all you have to show a message and interact with the user, you may consider writing a windows application instead of a windows service.

Windows Service dn't show message. if you show message you can write LOg FIle or you store message to DB

Hello, am new to C# programming, and would like to develop a small application with an in-built scheduler which would for example daily wake up my PC from sleep mode at 8AM and go to sleep mode at 10PM, the same routine going on the next day from Mon to Fri every week.
I do know about using Task Scheduler in Windows 7, but here would like to do it programmatically using C#. Anyone can help me finding the exact codes to perform this?
Thx...

This[^] is an article that shows you how to put the computer into sleep mode.

The task manager is for starting applications; you could write an application that shuts the computer down, but waking it up is a lot more challenging.

See here: Wake the PC from standby or hibernation[^] - it goes through the process and code pretty well.

Hello,
I am trying to learn functions in C#. I wrote the following test functions and I am getting the error: Error 1 An object reference is required for the non-static field, method, or property 'Testing_Functions.Program.Test(double, double, double)' C:\Users\computerpublic\AppData\Local\Temporary Projects\Testing Functions\Program.cs 18 29 Testing Functions.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace Testing_Functions
{
class Program
{
public Double Test(Double Val1, Double Val2, Double Val3)
{
Double Test_Val = Val1 + Val2 + Val3;
return Test_Val;
}
static void Main(string[] args)
{
Double A = 1, B = 2, C = 3;
Double Result = Test(A,B,C);
}
}
}

You have to declare the Test method as "static", just like your Main method.
Either that, you have to new up an instance of the Program class and use the Test method through that.
Serisouly, this is C# 101 stuff. You really need to pick up a beginners book on C# and work through it.
|
|
|
|

I am using the a book and I am following the example. I don't know why I am getting the error.
|
|
|
|

Look up the keyword "static", as that is why you are getting that particular error.

You're trying to call an instance method on an implicit this, but Main is static so there is no this.
|
|
|
|
|
The function "Main" is the start point of the program. When "Main" is called, no instance of any object could yet be created, hence it must be static.
From a static method, you can reach other static methods. Or you can create an object. When you create a e.g. new Windows Forms application in Visual Studio, it adds a line to Main: Application.Run(new Form1());. This creates a new object of type Form1.
Similarly, you could write another class, create the corresponding object, and call its function, e.g.
namespace Testing_Functions
{
class Addition
{
public Double Test(Double Val1, Double Val2, Double Val3)
{
Double Test_Val = Val1 + Val2 + Val3;
return Test_Val;
}
}
}
and then call it from your Main method:
Addition a = new Addition();
Double Result = a.Test(A,B,C);

I think it's been explained pretty well already, but just in case...
static methods are available without an instance of the class. Non static methods are only available through an instance of the class.
This gives you two options in your case. Either
1. Make the Test method static
public static Double Test(Double Val1, Double Val2, Double Val3)
or
2. Create a new instance of the class that holds the method (Program in this case).
Double Result = new Program().Test(A,B,C);
alternative
Program program = new Program();
Double Result = program.Test(A,B,C);

What is the C# equivalent to the following VB.NET code?
Delegate Sub SetStatus(ByVal Text As String)
Private Sub SetStatusStrip(ByVal Text As String)
Dim d As New SetStatus(Sub()
End Sub)
Me.Invoke(d, New Object() {Text})
End Sub
|
|

|

This seems homeworky but since you could just whip it through an autotranslater anyway, here you go:
delegate void SetStatus(string text);
private void SetStatusStrip(string text){
Invoke(text => {
}, new object[] { text } );
}
I think that's right. Invoke is a bit sniffy sometimes, you might need to cast the lambda, but I don't think so. Although it seems like the VB method you're generating for the delegate doesn't actually use a parameter so there's no reason you need to use that delegate for the inner method.

Doesn't sound like homework to me; I don't know any schools that mix VB/C#, but I do know that managers "insist" on keeping their codebase in a single language

I assure you it's not homework. I've been programming (promoted from drafting) for about three years. I started in VB.Net and am now trying to convert to C#. That doesn't seem to work. How can I cast a lambda expression? Thanks for the auto translate idea. I ran the code through a couple and none seem to work. Thanks for your help.

internal delegate void SetStatus(string Text);
private void SetStatusStrip(string Text)
{
SetStatus d = new SetStatus(() => {
});
this.Invoke(d, new object[] {Text});
}

Thank you sir. The following is what I ended up using and it works great.
SetStatus d = new SetStatus( (string myText) =>
{
});
this.Invoke(d, new object[] { _text });
