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()
[code].....
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).

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.

View 2 RepliesI have a https site where i have to display images from a http source. To enable this i want to make a proxy, so i can display the image as:
src="https://mydomain/showimage.aspx?url=http://externalserver/image.jpg"
I can do this in Java, somthing like this:
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.

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.

View 3 RepliesIve 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."}

View 16 RepliesI'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 want to know how can i code my button when i click it will open my site ... i Think i was clear.

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.
