locking - How can I lock the screen using C#? -

-

I just write my first c # application, which is a scheduler. I once wanted to pop up a dialog I want to lock the screen for two minutes to take a break.

As of now, my application only shows a form on "top-mast" when it's time to break it and hide it after two minutes.

How can I lock the screen? Something similar to the UAC style in vida.

As an option to grab a screen (which is also 'you also under the slightly different circumstances in the past Used as an Approach) You can also do this by creating a new window (WinForm) which is full screen and at the top of all other windows

If you have the background color of the window background solid black If you set the opacity to 70-80%, then you will find something that is available in U.A. Looks at the prompt.

For example. 

  formName.WindowState = FormWindowState.Maximized; FormName.FormBorderStyle = FormBorderStyle.None; FormName.Opacity = 0.70; FormName.TopMost = True;

Of course it would be sensible to pull a window at the top of informing a user that the screen has dimmed due to a counter.

Hold the approach with the screen, on its own basis, a user can access it by pressing the Windows key, Alt - tab or Ctrl - Esc to launch or switch to other functions. It's a bit more difficult.

asp.net - Javascript/DOM Why is does my form not support submit()? -

This is my first time working with asp.net and javascript, so I do not know very good web resources, or Much about javascript debugging I have to find out that on line oFormObject.submit (); Microsoft JScript Runtime Error: Object does not support this property or method I am using the link to work as a button because I am terrible in aesthetics and I think That link will look more professional than a table of 50 buttons. I have read that this solution can cause problems with browsers due to pre-rendering of my links and many additional traffic and problems, but CSS gives me a button like a link, which has issues of alignment and difference seemed to. & lt ;!

I am trying to implement one for Delphi, but there are some problems with communication. Fitnesse will start my process, and give me a portmember as a command line argument. Then I should make a socket on the port number given to me, and fitness will connect to that port I am using a TCPCP server for the job: < Pre> TcpServer1.LocalPort: = ParamStr (ParamCount); TcpServer1 Active: = true; On OnEXEPT () -Event, I send the protocol version to use as specified in the protocol. Process TForm1.TcpServer1Accept (From: TOBject; ClientSocket: TCustomIpClient); Var s: ansistring; Start clientSocket.

It shows that my code sends the protocol version, fitness sends back a message, and when I try to get this message

javascript - Classic ASP "ExecuteGlobal" statement acting differently on two servers -

-
I have a strange problem that I really do not know. In addition to developing a new ASP.NET site, I have to support the old "classic ASP" site. It is written in VBScript with a batch of JavaScript functions. Many of the JavaScript functions include 'files' Everything is fine on our production system (which security is controlled by another group - this is a military installation) Debugging them once did not work I). However, I have a fix for a vague bug that needs to be fully tested and some functions do not run under the "local" copy of the website that runs on my PC. For the record, I am running IIS 5.1 on XP. The problem is that some Javascript functions are running "OK" on the production server, but when they use it as a server, they are not defined on my PC what is happening that last Programmer, for some reason, has decided to put some functions in a series of files, which according to the observations, imitate the "need_once
