C# Auto click button and auto fill form

This tutorial will show you how to auto fill forms and click buttons in a website using the

webBrowser control When you learn to do this you can make your own web bots!

To show you how autoclick/autofill works we’ll make a simple Google AutoSearch Bot

So lets begin…

First of all, add a webBrowser control to your form Set its “Url” property to

“www.google.com”

Now we’ll add two methods SetText() and ClickButton() SetText() method will automatically fill

a textBox and the ClickButton() will click the submit button.

Since we are making a Google AutoSearch Bot we need to find what’s the name of the Google search textBox and the submit button To find these, visit Google.com from your browser and view the page source

Here’s the code for the SetText() method:

view source

Trang 2

// Set value for the attribute that has the name (attName)

void SetText(string attribute, string attName, string value) {

// Get a collection of all the tags with name "input";

HtmlElementCollection tagsCollection =

webBrowser1.Document.GetElementsByTagName("input");

foreach (HtmlElement currentTag in tagsCollection)

{

// If the attribute of the current tag has the name attName

if (currentTag.GetAttribute(attribute).Equals(attName))

// Then set its attribute "value"

currentTag.SetAttribute("value", value);

}

And now the code for the ClickButton() method:

// Click the button whose attribute has a name "attName"

Trang 3

void ClickButton(string attribute, string attName)

{

HtmlElementCollection col = webBrowser1.Document.GetElementsByTagName("input");

foreach (HtmlElement element in col)

{

if (element.GetAttribute(attribute).Equals(attName))

{

// Invoke the "Click" member of the button

element.InvokeMember("click");

}

Now that the main methods are added we can now tell the bot what to do

Declare “bool searched = false” at Class-level (i.e add it above pulic Form1() {……) We’ll use

it to check whether we have already searched or not

Add DoucmentComplete event for the webBrowser DocumentComplete event is fired when the

page is loaded completely

Use this code:

Note: The name of the Google search textBox is “q” and the submit buttons is “btnG”.

private void webBrowser1_DocumentCompleted(object sender,

WebBrowserDocumentCompletedEventArgs e)

{

Trang 4

// Check if already searched

if(searched == false)

{

// Set the text to "Search Text Here" of the textBox whose "name" attribute is "q";

SetText("name", "q", "Search Text Here");

// Click the button whose name attribute is "btnG"

ClickButton("name", "btnG");

// Since we have already searched, set it to true

searched = true;

}

That’s it! Debug the project and watch the bot

If you have any questions don’t hesitate to post a comment

Thanks

You can use this method to click a span:

Trang 5

// The Method:

void ClickSpan(string attribute, string attName)

{

HtmlElementCollection col = webBrowser1.Document.GetElementsByTagName(“span”);

foreach (HtmlElement element in col)

{

if (element.GetAttribute(attribute).Equals(attName))

{

element.InvokeMember(“click”);

}

// Example use:

ClickSpan(“class”, “yt-uix-button-content”);

Thanks
