I need to scrape data from a windows application to run a query in another program. Does anyone know of a good starting point for me to do this in.

Check out this page for an example of doing this in C. Second, you recursively enumerate the controls on that window with EnumChildWindows to find all of the window's child controls, and all of those children's children until you have a complete map of the target form.

Here is a selected portion of Theta-ga's excellent explanation from Google Answers:. To get the contents of any textbox or listbox control, all we need is it's window handle. If you have already obtained the window handle then move to part 2 of the explaination.

Here is a selected portion of Theta-ga's excellent explanation from Google Answers: To get the contents of any textbox or listbox control, all we need is it's window handle.

PART 1: Obtaining the control handle To obtain the handle of a control, we first obtain the handle of it? We can do this by using the Win32 FindControlEx method. Once we have the parent window handle, we can call the Win32 EnumChildWindows method. This method takes in a callback method, which it calls with the handle of every child control it finds for the specified parent.

For eg. Since we are only interested in the handle of the textbox control, we can check the class of the window in the callback method.

The Win32 method GetClassName can be used for this. This method takes in a window handle and provides us with a string containing the class name. So a textbox belongs to the? Once you have determined that you have the handle for the right control, you can read its contents. This will give you the text content of the control.

This method will work for a textbox, button, or static control.

However, the above approach will fail if you try to read the contents of a listbox. HanClinto HanClinto 8, 3 3 gold badges 26 26 silver badges 30 30 bronze badges. Quick question, if I have rectangle coordinates i.Jump to navigation. The real internet teases at times by making data available, but usually in HTML or PDF documents—formats designed for data display rather than data interchange. Accordingly, the screen scraping of yesteryear—extracting displayed data and converting it to the requested format—is still relevant today.

The request traffic from the user's browser to the Plack server and then to the server hosting the data. The source code and data file data. Here is a quick summary of the pieces, and clarifications will follow:.

The plackup command starts a standalone Plack web server that hosts the Scraping program. The Scraping code handles request routing, extracts data from the data.

Creating a Web Text Scraper with Visual Basic

Because the Plack server runs indefinitely, the Scraping program prints the process ID, which can be used to kill the server and the Scraping app. This function, as the request handler, then starts the job of retrieving the data to be scraped, scraping the data, and generating the final report.

The data-retrieval part falls to a utility function, which uses Perl's LWP::Agent package to get the data from whatever server is hosting the data. The data. Here are the three critical lines of code for the data extraction:. After the call to the TableExtract::parse function, the Scraping program uses the TableExtract::rows function to iterate over the rows of extracted data—rows of data without the HTML markup.

The next step is to process the extracted data, in this case by doing rudimentary statistical analysis using the Statistics::Descriptive package.

In Fig. The final step in the Scraping program is to generate a report. The template file is report. Here is how the code and the template interact. The report document Fig.Language : Translate W.

Web Scraping Library (Fully .NET)

Language :.Web scraping is a term that is becoming increasingly popular in the development world. It could because developers always tend to try to make things more and more convenient for users. At first, I wasn't a big fan of scraping because it can be used to obtain data not intended to be had by a user.

Today you will create a program to scrape text from a website. Here is a nice definition of Web Scraping. Open Visual Studioand create a VB. NET Windows Forms project. Name it anything you like and design it as shown in Figure 1. Figure 1 - Our Design. Not much coding.

Screen Scrapes in ASP.NET

Be warned though, that doesn't mean that the code you will learn today will be easy. Nothing worthwhile is ever easy. Now, you're not here to learn about my life lessons, nor philosophy. Let's get the show on the road. You will use the System. Text and System. We need to take all of these factors into consideration when dealing with web pages. The System. Net namespace provides objects such as the WebResponse object that provides a certain response to a calling application, and the HttpWebRequestwhich enables us to understand the HTTP text.

This protocol deals solely with web pages. IO namespace will give you the StreamReader object, which you can use to read any stream of data. Let me break my logic down for you. I created a string object to hold the URL Universal Resource Locator, in layman's terms it means a web address from which I will be scraping text.

In this case it is Codeguru. After I create the request, I send it via the WebResponse object. This object returns the text sent from the HTTP protocol back to us. Now, the tricky part Once we have the text, we need to format it appropriately.

This is where the Regular Expressions come in. If you haven't heard of Regular Expressions before, have a look through this article of mine.NET version 3. Introduction One of the great things about ASP. NET Web page. This is because ASP. NET has access to the hundreds of. NET Framework classes, which are the same set of classes that all. NET Web page to a stand-alone Windows application use.

Some of the neat things that can be accomplished in an ASP. This article will focus on how to quickly and easily perform a screen scrape via an ASP. NET Web page using the System.

WebClient class. Not surprisingly, there are a gaggle of articles on 4Guys explaining how to perform screen scrapes in classic ASP. NET, we will be using the WebClient class. For those who have spent much time working with the Beta1 code, understand that this class is new to the Beta2 code release. This class is located in the System.

Net namespace. The complete technical docs for this class can be found here. The simplest use of this class involves just a few lines of code.

Screen Scraping with C# for ASP.NET

The steps we need to perform include: Creating an instance of the class Calling the DownloadData method, passing in the URL we wish to scrape which returns an array of Byte s Convert the downloaded data's Byte array into a String Once we accomplish these three steps, we'll have successfully scraped the content from another URL and have it sitting in a String variable, ready to manipulate or display however we see fit.

So let's get started! Below you will see the code for an ASP. GetString objWebClient. Pretty simple, eh? For more information on ASP. NET Article Index! For More Complicated Screen Scrapes However, if you need a more advanced HTTP request - one that tunnels through a proxy server, perhaps, or one that you want to specify a timeout for - you'll need to use the HttpWebRequest class instead.

NETbut finally without the use of Microsoft mshtml parser! I often use this light version because it is simple to customize and to be included in new projects. Doing so, it will be simpler to locate data inside a web page. The base architecture, then, focuses on making this transformation and executing queries on the XML result document.

The Parser class includes all functions to navigate and parse. At this point, another object, the ScrapeBot can execute queries, extract and purge desired data with XPath syntax. The gkScrapeBot is the main object you will use in your project. It already uses the Parser for you.

It provides some wrappers to navigation functions, some useful query functions and some other functions to extract and purge data. This component is written in VB. Why not Microsoft Parser?

Ah, ok. I want to spend a little time to write about this painful choice. The first version of this project was made using mshtml. This is why I decided to change: First: my intent was to use this component windowless. There are many documents on the web about using mshtml. No one official from Microsoft. However, a lot about users troubles… The only few useful documents from Microsoft are dated walkall example from inet sdk!

It works, but I quickly found its limitation. Second: Then I start coding. NET based on walkall example. And POST? Microsoft writes about this. It writes that you have a total control on this… NO!

I see that work only if hosted by the heavy MS WebBrowser component. Then: I understand that Microsoft does not like developers using its parser.This project is not earth shattering or revolutionary, it is simply a means of coming to terms with ASP.

NET and C development on my part, and to hopefully expose some knowledge and ideas to others. This project began with the need to create an intranet portal that contained, among other things, the local weather forecast. Since I could not use their site, nor was paying for a service to provide the information an option, it was determined that screen scrapping the local TV site would be a good solution.

I decided this would be a good introduction the. NET with C as the coding language. It should go without saying that screen scraping is not the best solution in many cases. You are completely at the mercy of the third party site, if the layout changes, you must rework you solution. In my case I was able to search for the heading. The weather information was found in two tables so it was just a matter of searching the HTML text and extracting the tables. I could then pass this as the innerHTML content for a table on my webpage.

Using the. As can be seen we just need to create a WebResponse object and feed the ResponseStream into a instance of StreamReader. From there I parse through it to remove the empty lines and assign the result to a string.

I'm using StringBuilder. Append method as an alternative to appending to the string based on the recommendation of Charles Petzold in Programming Microsoft Windows with C. Here he demonstrates the using the StringBuilder is x faster than appending to a string.

After the text has been acquired it is simply a matter of extracting and returning the substring. To fix the relative path of the images I run the substring through another method to insert the absolute path before returning it. The complete site used ADO. They also had the ability to add events to their calendar. For simplicity I choose not include these features in this sample. NET exploration to give others some ideas.
