I had to check, you are obviously new to CP, so read the guidlines, decide wether this is a forum you want to use as your development LEARNING resource.
From this question I do not expect to see you here again, except possibly to trade insults because we will not send you the code.

In a Winforms application? I'd make a Menu item and set Ctrl+S as the hot key.
(Or I could be completely wrong; I ate a handfull of chocolate-covered espresso beans.)

Just listen for the KeyPress event of the form (if it's in fact a WinForm application). When the key, or the key combination, is pressed just run your method. For instance:
this.KeyPress += new System.Windows.Forms.KeyEventHandler(this.MyApp_KeyPress);
private void MyApp_KeyPress(object sender, System.Windows.Forms.KeyEventArgs e)
{
if (e.KeyCode == Keys.F5)
{
this.MyMethod();
return;
}
}
private void MyMethod()
{
MessageBox.Show("MyMethod");
}

Hey,
I got a project to make an video application (that I can see myself on windows form).
The problem is that I dont know how to do that kind of things, so I searched the net and found the WIA COM and thinking of using it.
I found that article: WIA Scripting and .NET[^]
But for some reason my computter says that the COM "WIALib" not exists... so I continued search and found that:
http://www.codeguru.com/forum/showthread.php?t=439027[^]
But for some reason, the line
CommonDialogClass class1 = new CommonDialogClass();
Gives me an problem
Error 2 Interop type 'WIA.CommonDialogClass' cannot be embedded. Use the applicable interface instead. C:\Users\Yahav\Documents\Visual Studio 2010\Projects\ControlCamera\ControlCamera\Form1.cs 69 40 ControlCamera
and the same for that:
DeviceManager manager = new DeviceManagerClass();
Someone can explain me why?
Thank you very very moch! Yahav.

In the properties of assembly,
Change "Embed Interop Types" To 'False'

Hi all, I am trying to use SQLite database for my App. It seems like I can insert datetime into datetime column.
Does anyone know how to do this.
thanks in advance.

If you use a parameterised query, it will take care of any data type conversion for you. What have you tried ?

purpose
I am implementing a singleton "message queue". Several threads will enqueue messages to this queue and the worker thread will dequeue messages and process the message.
problem
in the line: "instance.threadWorker = new Thread(new ThreadStart(MessageWorker));" causes the error...
"An object reference is required for the non-static field, method, or property 'Application_Messaging.class_MessageQueue.MessageWorker()'"
code
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading;
#pragma warning disable 0628 //suppress "new protected member declared in sealed class"
namespace Application_Messaging
{
public sealed class class_MessageQueue
{
private static class_MessageQueue instance = null;
private static readonly object padlock = new object();
private Thread threadWorker;
protected class_MessageQueue()
{
}
public static class_MessageQueue Instance
{
get
{
lock (padlock)
{
if (instance==null)
{
instance = new class_MessageQueue();
instance.threadWorker = new Thread(new ThreadStart(MessageWorker));
instance.threadWorker.Start();
}
return instance;
}
}
}
private void MessageWorker()
{
}
}
}
how can I get the worker thread running ?
|

Should the thread be spun off in the constructor?
And why have the constructor protected rather than private?
|
|
|
|
|
"protected" is how Microsoft showed the singleton pattern on MSDN
|
|
|
|
|
I bet they didn't seal it though.

A static constructor/method/property cannot access any non-static members in its class; that includes both data members and code members (constructors/methods/properties).
==> make MessageWorker() a static method.

This[^] seems to suggest it isn't; and I wouldn't make the queue neither static nor singleton myself, however it was my attempt to answer the question in general, allowing the OP to get the code to compile.

My original intent in creating the message queue as a singleton was purely for good design. Now I'll rework the class and simply ensure that the class isn't instantiated more than once.
