Get Resolution Of Local Machine in TypeScript Using ASP.NET

Introduction

In this article, I will explain how to get user screen resolution or local machine resolution.

Step 1

Open Visual Studio 2012 and click "File" -> "New" -> "Project...". A window is opened. In this window, click "HTML Application for TypeScript" under Visual C#.

Give the name of your application as "Get_Resolution" and then click "Ok".

Step 2

After this session, the project has been created; a new window is opened on the right side. This window is called the Solution Explorer. The Solution Explorer contains the ts file, js file, and CSS file and aspx page.

Coding

Resolution.ts

class Get_Resolution {
Resolution() {
var txtwidth = < HTMLTextAreaElement > document.getElementById('txtwidth');
var txtheight = < HTMLTextAreaElement > document.getElementById('txtheight');
txtwidth.value = screen.width.toString();
txtheight.value = screen.height.toString();
}
}
window.onload = () => {
var bttnresolution = document.getElementById("show");
var obj = new Get_Resolution();
bttnresolution.onclick = function() {
obj.Resolution();
}
};

Get_Resolution.prototype.Resolution = function() {

var txtheight = document.getElementById('txtheight');
txtwidth.value = screen.width.toString();
txtheight.value = screen.height.toString();
};
return Get_Resolution;
})();
window.onload = function() {
var bttnresolution = document.getElementById("show");
var obj = new Get_Resolution();
bttnresolution.onclick = function() {
obj.Resolution();
};
