Display The Data (prices) From Some Hard Drives From Some Site's?
Jan 14, 2012
I have a small app and i want to display the data (prices) from some hard drives from some site's. I use this code
Dim PageElements As HtmlElementCollection = WebBrowser1.Document.GetElementsByTagName("img")
For Each CurElement As HtmlElement In PageElements
TextBox2.Text = TextBox2.Text & CurElement.GetAttribute("src") & Environment.NewLine

I'm trying to get a list of current hard drives (that part is done), but then go through the list one by one and remove those that have no size (dvd drives for example). I'm sure this is horribly wrong (4 errors are shown in the list). Could someone give me a hand?
Here is what I have so far:
ComboBoxHD.Items.AddRange(System.IO.Directory.GetLogicalDrives) Dim dInfo As New System.IO.Directory For Each drive As System.IO.Directory In dInfo.GetLogicalDrives()
I want to make 2 dynamic comboboxes; The first will list all the hard-drives/thumb-drives etc, the second will list all the CD/DVD drives.Beneath each combobox there will be a set of buttons that control the selected drive:Beneath the hard-drive combobox there will be two buttons: one is "open" (will open the select drive in explorer) the other is "remove" (checks if the selected drive is removable and if so safely removes the drive).Beneath the CD/DVD combobox there will also be two buttons: one is "open" (will open the drive's contents, if present, in explorer), the other is "autorun" (will execute the autorun for the disc).
I have a school project, and for some reason in the book it doesn't show how to keep a variable cross sub functions. Can anyone give me a clue of what i'm doing wrong ?
Here is my code Private Sub processButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles processButton.Click
i have a form and it has checkboxes that are different prices for options on a car. my problem is I don't know how to write the code to add the checkbox prices up to display in the lable.
This is what I have so far, I know it should be simple as hell, but I'm having a huge brainfart at the moment. Im going to continue messing with it though. Im trying to make it so I can input a number for a percentage, multiply that with my current array prices, and display the total in the listbox. I have a few theories on why it isnt working but cant pinpoint which one to use, I'm at a basic level to this and still learning the process. Im also pretty sure I dont have everything I need on here yet.
So I have a code atm that has 2 combo boxes, one to select the make, then it will enable the model, I have 3 model choices, here's code: [code] Once I have selected my model of the car, it takes me to that specific form with a picture of that model, I then want to display individual parts, with individual prices that will add up in a text box above.
Basically i would like to get the Initial Size For the (C Hard drive, and then display it in a textbox. Heres a diagram of what i want. Code > Get.(C.Size > hddsize = harddrive size > TextBox2.Text = hddsize.
I would also like the code to get the Harddrive name, and display it in a ListBox - Diagram Time xD Code > Get.(C.Name > hddname = harddrive name > ListBox1.Text = hddname.
Code: InputStream in = new WebInputStream( url ); BrowserOutStream out = new BrowserOutStream(); while(in.read()){ out.write() }; in.close(); out.close();
Simple enough (although the code is simplified here). But i cant seem to find a proper example of the equivalent in vb .net. I am assuming i have to use System.Net.WebClient.OpenRead, but not sure where to go from there.
I was using ContentType="application/vnd.ms-excel" on my web site to display a datatable in an excel workbook on the client. It worked great. Now that I have upgraded to Office 2007 and vb.net 2010, I get a warning saying that the file is in a different format than specified by the file extension (.xls). I googled new ways of exporting data to excel, but have yet to find a good example. I usedMicrosoft.Office.Interop.Excel which worked great, except I read that you are not supposed to use this on a web server.
I am trying to write an application that accesses the SMART data from a hard disk, so I can show all the values and whether anything is over the threshold or failing etc Have spent many hours trawling the web without any success.
I found something very strange, in the data base explorer I modify the conection to the location of the data base(F:My DocumentsMy ResepteResepte.sdf) , but after raning the app. the path is back to what it was in the project folder and so the same in the selution window. It is set to Do Not Copy. How can I change this so that the IDE looks at the propper data all the time.
I am not sure if this is possiable but I am looking to build an application that will login to a web site, navigate the site and download files. I would like to do this all in code and able to run multiple instances of the program to get information from many different web sites. Is something like this possiable in VB.net?
Ive got an app that holds a list of site we have, At each site there are a few devices. The idea is when they click on a site all the details for the site are loaded and then a second thread sits and pings each device to see if its live. Im trying to do this in a seperate thread so if they click another site while its still pinging them it doesn't wait before it switches site. This all seems to be workling fine except if you click through the sites quickly, when you do that it will eventually come up with

{"Collection was modified; enumeration operation might not execute."}
The error flags up on the "Next" line in "ThreadedPing"

When i publish my program i choose to let the application check for updates via a website and if their is one update automatically when the program starts. Is their a way were on the main user form i can make it so that the user can change the update site with out me building the program again with the new site. I want to do this becuase the site i use goes down alot so when i changed the update url no one was able to download the update for the new update server.
I'm deploying a VB.Net app (VS 2010 Pro) that requiers the user click a command button to open IE to a financial WEB site and download informaion from the site. The app works fine in every detail when installed on the development computer. But, on the target computer when the command button is clicked an unhandled exception occurs which says: System.IO. FileNotFoundException:File Not found.My code behind the button is Shell("C:Program Files (x86)Internet Exploreriexplore.exe www,fidelity.com",AppWinStyle.NormalFocus)
This works fine on the development computer. Do I need a way to code this as a relative path? If so,can you tell me how this is done?Throughout the app I have written relative paths to needed files using paths like (Open(Environment. GEtFolderPath (Environment. SpecialFoldder.Desktop) + "File Name). They all work fine when deployed.
I'm being asked to maintain several internal-only web apps for my company. For testing, after making my changes, I've created some staging sites which make use of separate databases. As such, if my users were to mistakenly use this site as if it were the production site, they may enter important data and wonder where it "disappeared" to thinking it was the production server.
I'd like to create a big banner of some sort across the top of the staging site (which ONLY appears on the staging site) to remind my users that they are on the test site. I'd like recommendations on the best way to do this, with the following considerations:
IDE: Visual Studio 2008 Server: Windows 2003 with IIS 6 Language: VB.NET 2.0
I have a textbox where a user enters a code that is connected to their account. It will then display a welcome message in place of the textbox where they entered their information. It used to work up until I added more code for it to query another database. That ended up messing up my page and since I have deleted that code, I must've forgotten something, or maybe my code was messy to begin with....but now my welcome message is always the wrong person's name. In fact, no matter what code you type in, it displays the same person's name.This person doesn't even have a code in the database. I tried adding IS NOT NULL and ISLIKE 'B%' so that i

I'm watching tutorials about creating Web Site and about controls.I think I added SQL Database to the project (it's not empty) properly. Suppose it has two columns: FirstName, LastName.I have TextBox1, TextBox2 and Button1 on the web site form.I enter any integer number (5, 10, 15 or whatever) into TextBox1. I want to press Button1 and get a value of 5th person (10th, 15th or whatever) from SQL Database into TextBox2.Who can help me with that? Should I read about ADO.NET and use something from there?Later I want to use VB for work with that strings.
I'm trying to make an application which will log me into a site and read the text of the site and display a certain part of that text in my form. I'm stuck at the login, its a .php page with 2 text boxes, 1 check box and 1 button.Is there any way to manipulate those objects by using controls in my form?
I want to build a VB program that will go to a web site and pull out a specific piece of data.I am using VB Express 2010 not sure if it belongs in this .net forum.I am successfully getting to the website using WebBrowser.navigate()The data is provided to me in XML format and I am told that it is ready to be retrieved. They tell me to use XML Parser.When I go to their web site I see the data I need to pull out there is a column with tags in front of each piece, the piece I need is between <Vr0> and </Vr0>.I have no resources other than the net currently I do have a dummies book ordered but will be at least next week (at the earliest) before my first book arrives.Can you explain how I can sort through the data and pull out the data in XML format on a web site?
