My program so far reads a certain webpage's source code and places it in a textbox. This much has already been accomplished.
Now I need to pick certain strings out of the rather large amount of text data and have the lines stored in variables, but the trick of it is, the exact string is unknown. The exact function should be, that the code finds certain tags from the source code, say <td> and </td> and takes the string data in between those tags, what ever it may be.

What I'd like to do is when a user clicks a button in my windows form application, it launches IE etc and opens webpage, sends the username/password stored on the pc and logins into the main page.Some background-the password will be stored in a txt file on the pc in encrypted form-the webpage am login into is a aspx company intranet page-security is really not a major issue as everything is internal-the main page of the intranet page is just two textboxes asking for username/password before going any further. There is a button to login on the webpageIs what am trying to do possible as I really do not have understanding of how the login page works underneath or for that matter much about HTTP post requests etc

I am trying to create an application that will login our company's intranet portal via a webpage. The webpage has a single frame in it that loads a secure(https) login form. After logging in, the application will need to read and send xml to and from the portal. I have been digging around and have seen a few different ways of submitting the login information from the program to the site, however, I have not gotten any of them to work. From what I can tell it is difficult to change the values of input boxes that are inside a frame. Am I accurate on this? There will be a large amount of data transfer between the app and the portal so I will need something lightweight but I have enough room that I would rather not reinvent the http/web-browser wheel if at all possible. The reason I say that is because I have read that some objects that handle web pages are very resource hungry. I have no preference on the .net frameworks as this is the area of VB thats kinda confusing. What I am looking for is either a point or violent shove in the right direction.

I'm creating a reporting application in Windows Forms. The application will allow the user to browse and search within a database table, but I also want it to integrate with a 3rd party web page that reports on related information. I understand it's simple enough to view the web page, but, integrating with my application will be quicker and easier. The web pages shows "operational status" on individual recording systems for the call centre telephones. To make sure that these recording systems are working correctly, a list of the extensions whose recording systems aren't working is drawn up. I want my application to draw up this list automatically, but to do that, I have to get it off the web page first.

I'm trying to write an application that will notify me when a webpage changes. I used a web browser form and it opens the main website fine. You have to click a submit button to get to the page that I need to track. After this page opens I copy the text I want to track into an input box and then I need to refresh the page every minute or so to see if the text changes.The problem I am having is I cannot get the page to refresh properly. I send the WebBrowser1.Refresh() command but my ap stops responding, but only sometimes. If the refresh works then I get a popup window where I need to send [enter] to get the page to

've written a desktop application in VB.net which gets data from numerous serial devices and graphs it in a windows form. What I'd like to do enable remote users to view this data remotely from a web browser.
So, is it possible to add a webpage to a desktop application which could be dynamically updated from from my windows app or do I have to rewrite the entire application in asp, flex or silverlight so it can be viewed remotely via a web browser?I'm not familiar with asp flex or silverlight and have only developed desktop apps using vb.net 2010 on win7 and XP.

We have a company intranet and the powers that be think it would be nice to have a collection of icons/links representing the applications that most reps use (Outlook, Excel, few other apps).
The idea would be that if the application is installed, clicking the link/icon would launch the application on the client machine.
Anyone ever had a requirement like that and been successful implementing it?

I am developing an application for internal use in our company. The purpose of this application is for document imaging. What we are wanting to do is print a barcode label to attach to documents so that when they are scanned in a piece of software such as vfiler will be able to read the barcodes and know how to file them.The main focus is our ERP system which is web based (PHP). We are wanting to modify the code to allow the user to print the barcode label immediately once they enter an order or PO. I have access to the source code for the ERP web pages. I don't know of any way to make a web page print to a printer without displaying the printer select dialog. So, I decided that I wanted to try and create a VB application that would do the printing of the barcodes. This would allow me to bypass the the printer select dialog.
Now for the question. Is there any way to have a web page (PHP) running on the server call a VB app to perform a task? So, if I had a button on the webpage and the user clicked it, that button would somehow send the pertinent information (Order number) to the VB app and the VB app would print the barcode. The VB app will always be running on the machine. The label printers will be Zebra USB label printers on each person's machine.

I've search numerous hours, but I haven't been able to find the appropriate solution. What I want to do: Get the html of a certain webpage (Lets say in this case url...this html within my wpf application, so that you can see the content of the page you requested. Then I want to be able to trigger events on the html that has been loaded from the URL. Like I want you to be able to click on a certain node in the HTML and I want to be able to link this node to a certain value. Basically a crawler application that let's you request a page, see the page in a control and allows you to click in the loaded HTML and link values to predefined values you set. So basically I want to be able to get a webpage displayed within my application and be able to trigger events on the html (For example a click on the html which would need me to know on what node you clicked in the html, or for example be able to edit the html by clicking in it).

We have an ASP classic ERP (very large application) that we want to rewrite using ASP.NET. I am looking for a way to organize the application so we are going to be able to separate every program / webpage (over 400) from each other. Every program needs to be independent because many developers will work on the project at the same time.Visual Studio seems to make a DLL for every assembly so I was wondering if it's a good idea to make a huge solution with one project per DLL.[code]This way, we would be able to deploy every program separately without altering the others. We would also have over a thousand DLL to manage...

Is there a .Net control I can use to display a web page from a vb.Net windows forms application?
I am writing an app that will produce a slide show from a specified directory. The idea is it will ideally include Images, Video clips (via Windows Media), URL's (held in a text file), PDF documents and power point presentations.
Images and media clips aren't an issue. At present I am looking at displaying specified web pages. I am aware that I can use
System.Diagnostics.Process.Start("http://webinta/Pages/Home.htm"
to open a browser window, but I want control of that as after a specified amount of time it needs to close so I can display the next image (media clip, url etc).

Is there any way i can get the asp.net web page to read the directory path stored in the app.config file? Should i look to use the web.config file at all?

I like to make an console application to measure the time it takes to fully load a web page, what's the best approach to do that? The purpose of this small app is to monitor some pages in a website, in a predetermined interval, in order to be able to know beforehand if something is going wrong with the webserver or the database server. It would be nice to be able to measure the time it takes to fully load the the page (images, css, javascript, etc). I have some code but I is not measuring the fully page.
Dim sw As New System.Diagnostics.Stopwatch
Dim req As System.Net.HttpWebRequest = CType(HttpWebRequest.Create("[URL]"), HttpWebRequest)
sw.Start()
Dim res As System.Net.HttpWebResponse = CType(req.GetResponse(), HttpWebResponse)
sw.Stop()
Dim timeToLoad As TimeSpan = sw.Elapsed

im developing an application that constantly checks a particular webpage for changes in the page. im using the webbrowser.documenttext to read changes in the source, its working great. until when i tried to use webbrowser.refresh(), an ugly popup that says. "To display the webpage again, Internet Explorer needs to resend the information you've previously submitted.If you were making a purchase, you should click Cancel to avoid a duplicate transaction. Otherwise, click Retry to display the webpage again."

A couple of months ago, before I started learning C++, I made an application in VB.net that reads memory from an external program. This could be anything, from notepad to windows media player etc. I have been trying to find a way to do the exact same thing in C++, but to my suprise I can't find anything straightforward on the subject. All google comes up with is threads on several forums, where the general response is "Windows doesn't allow you to read from memory you do not own". But if it works in VB.net, it can work in C++ too.

I have created a program which should perform a certain action whenever a certain group of keys is pressed at the same time. The program must be able to run in the background, or in the system tray or something. Essentially, this should work like the KeyDown event on a form, except the form in this case is everything.
I'm not certain if there is a way to do this directly from within the .net API, but if there is I certainly have not found it.

One thing is if it doesnt ping it doesn't say anything its just empty space.
