Use A For-each Loop To Enable Each Element?
Dec 23, 2011
If I want to enable a bunch of textboxes and I have the names of the textboxes stored in a string array, how can I use a foreach loop to enable each element?I've tried the following, but it doesn't work.
Dim strElements = New String() {"chkFirstname", "chkLastname", "chkCompanyname", "chkFullname", "chkContactTitle", "chkEmail", "chkAddress", "chkCity", "chkState", "chkZipcode", "chkHomePhone", "chkWorkPhone", "chkFaxPhone"}

I'm trying to create an app with a backgroundworker to enable canceling a loop, but it won't work as I hoped it would.When I debug right after the line ThreadWorker.RunWorkerAsync() the programm goes directly to Private Sub ThreadWorker_RunWorkerCompleted and skips the Private Sub ThreadWorker_DoWork part, where of course the actual code is in (I've left that code out, it's about a 100 lines and without BGW it works).Does anyone have an idea what could be wrong with it?

I have a number of rewrite rules for a lot of things that I did in IIS7, like removing trailing slashes, canonnical URLs, lowercase lettering, and such. IIS altered my web.config, and everything works fine on the website, like it should. But in the Visual Studio web.config, the opening < rewrite > statement is underlined in blue, and at the bottom of VS, it says that the element 'system.webServer' has invalid child element 'rewrite'. But this is how IIS made it. I didn't do this manually. Should I be concerned with this VS error, or should I just leave as be, since it's working how it should work? Here's an example of my web.config:

I have been doing well and also I am a noob I know it and you know it a lot has started making sense and I am evening figuring new things out without using Google but of course I have hit another snag in my program so here goes
I am waiting for an email to arrive (the page automatically refreshes) and then I want to click the link (I do not need to click to open the email or anything like that) I also have the code to click and navigate to the address reason being it was the only way I could figure out how to stop it opening in a new window on IE
So my only problem is I need a way to check every x seconds for the element and then if its there proceed with my code and if its not wait and then check again or however this is done in VB.If this is not the way its done please point me in the right direction the code I am using to find and then navigate to the link is
Dim emailpageelements As HtmlElementCollection = WebBrowser2.Document.GetElementsByTagName("a")
For Each emailver As HtmlElement In emailpageelements
If InStr(emailver.InnerHtml, "https://twitter.com/account/confirm_email/") Then
WebBrowser1.Navigate(emailver.InnerText)

I want to be able to reference an element in an array of structures by the name of the element in a visual basic 2010 function. For example
Public Structure myStruct
Public element1 as string
Public element2 as integer
Public element3 as boolean
[code]...
Is it possible to reference a structures element by the element's name in a similar way to that shown above. The code shown above does not work, as the expression obj(i).[elementName] does not work as hoped.

Makes the following statement about the code below:
**"The computer evaluates the loop condition in the Do...Loop statment to determine whether the loop instructions should be processed. In this case, the inputsales <> String.Empty condition compares the contenst of the input sales variable to the String.Empty value. As you know the String.Empty value represents a zero length, or empty, string if the inputsales variable is empty, the loop condition evaluates to True and the computer process the loop instructions. *If on the other hand the inputsales variable is not empty, the loop condition evaluates to false and the computer skips over the loop instructions.
Based on the code I think it is the opposite: ...that while the inputsales value is not empty it should evaluate to true and process the loop and if it is empty it should evaluate to false and skip the loop?
See below.

Option Strict On

I am constructing a program, i am new to Visual Basic, but i have past programming experience. I was wondering if anyone knew how to form a loop that could...lets say calculate the answer when two numbers are added together,and it would repeat this thousands of times, etc. And if there is a way, would it be possible to calculate the time taken to complete this loop.

I have written a function that gets the alexa ranking of a given url, now this function works perfectly but I want to loop through a ListView of urls and grab the alexa rank of each item (url) with my function.The code works great if I put a MessageBox in the loop to test that the function is returning a value but when I remove the MessageBox the loop does not work.I need it to loop through adding each result without a MessageBox stop in each loop.
vb
For Each Item In ListView1.Items
Dim result As Integer
result = GetAlexaRank(Item.Text)

So I made a simple patform game where the player has to jump quickly while the platforms move to the bottom of the screen, as to not touch the bottom of the screen. But, I need to know how to create a loop to loop the locations of the platform. This means that after twenty or so platforms, the same platforms come up again, so that the player will have an "endless" game. I've declared all the platform's locations relative to the location of the first repeating platform:

I was wondering if it is possible to allow the add-ons that were developed for IE to work with webbrowser control.
I am working on a browser that uses the webbrowser control. I need to add certain features like ad-block to it. I noticed that these features are available as add-ons already for IE. Since webbrowser control is IE-based, I was wondering if it was possible to enable the webbrowser control to access these add-ons?

I have been working on my application for quite a long time, and now that I get to the closing stages I have hit a wall that I cannot quite get over (or work out how to get over ). My problem is that my application needs to be able to; edit registry keys, create them, and eventually delete them. Thats fine I have the code for it. The problem occurs because my app does not have the required security settings. I have been looking at this and came up with an idea
In the my project tab there is a tab called settings and I have enabled custom security with everything ticked but the problem is, is that my application still does not have the required permissions to edit the registry . So my question is... How Can you enable a program to edit the registry?
