Javascript - JS EventListener Equivalent In VB 2010
Jul 18, 2011
I have this problem: I need to be able to catch changed in DOM elements in a page that I am loading in a Visual Basic webBrowser control. Normally in JavaScript in Firefox I would do something like this: element[0].childNodes[1].addEventListener("DOMAttrModified", functionX, true); where element[0] is the element that I need monitored and child[1] is the 2nd child for this element that has its text value changed which I need to catch when it changes, while functionX is the function/sub that I want to trigger everytime there is a change in element[0].childNodes[1].

Using this code on the javascript side and
Using sha As New SHA256Managed
Using memStream As New MemoryStream(Encoding.ASCII.GetBytes("Hello World!"))
Dim hash() As Byte = sha.ComputeHash(memStream)
Dim res As String = Encoding.Default.GetString(hash)
End Using
End Using
I have been unable to recreate the same hash for the same values with these two bits of code.
The javascript implementation returns: 7f83b1657ff1fc53b92dc18148a1d65dfc2d4b1fa3d677284addd200126d9069
and the vb.net example returns: ƒeñüS-ÁHÖ]ü-KÖw(JÝÒ mi"
What am I missing? I assume it's something to do with the character encoding?
So for anyone interested it was 1 simple change.

This is starting to drive me nuts. I'm executing a DTS package from a worker thread that is calling an EventListener class to update the background worker ProgressChanged sub. As instructed, the ProgressChanged method is trying to update a progress bar to avoid thread issues but it is not working. I know the EventListener is throwing events because if I put a message box in ProgressChanged I get the package progress %. Why can't it update the progress bar?

I am trying to get the following VB6 listindex to work within my vb.net
setTheR CStr(payReq.ItemData(payReq.ListIndex))
But if i copy and paste that into VB.net it wont accept it.
This is what VB.net did with the converting of the VB6 to .net
strContract = payReq.Items.Item(payReq.FocusedItem.Index).Text
However, checking that value it returns the name instead of the index. While the VB6 code returns the value of 2311 (which is what it needs to return)
When i add items to the listview i do this:
Item = payReq.Items.Add(rsPayRequests.Fields("userid").Value)
Item.SubItems.Insert(1, New System.Windows.Forms.ListViewItem.ListViewSubItem(Nothing,
[Code]...
But that does not work with my listview in .net since that above is a listbox and not a listview. Is there an equivalent in .net for the listbox to have a custom index?

Is there an equivalent to Java Properties in VB. A Properties file in java is a place where you can save propeties for an application. So if an application looks at a file on a server (which could change) you could save to location in a properties file the if the location changes you just change the properties file. You do not have to recompile the program.

I'm currently trying to create a Visual Basic 2010 Installer for an application that I recently created. The idea of the Installer will push the necessary JavaScript Files to the designated location and also create the program for users to use.
Problem: I am trying to incorporate the Javascript files into my Installer so I can push it into the user's files - of course, checking if that file structure is installed or not, but I do not know how.

An action that I'm trying to automatically complete on a web page requires me to click "Yes" on a JavaScript alert box. Obviously the entire process cannot be automated unless the program clicks "Yes" or "No" for the user. Is there any way that I can capture this alert box and click "Yes" programmatically?

I know that AndAlso is equivalent to && and OrElse is equivalent to ||. But what is the cleanest way to achieve the equivalent of Visual Basic's And and Or in C#?For example, consider the following VB.NET code.The ValidateForControl method performs some validation and returns whether the state of the specified control is valid. The entire input form is valid if all controls are valid. However, each control must be individually validated even if one is invalid (which requires the operator not to short-circuit). Visual Basic's And operator is perfect for this situation, but unfortunately there's no equivalent operator in C# as far as I know (&& short-circuits).

What I am trying to do is to check if a value matches one of two numbers (and easily be able to add to the numbers to compare to). Rather than doing a longer-winded way such as: [Code] I have found that this only works when SectionID is 2 or PageID is 8. If SectionID is 3 or PageID is 12 then it doesn't work. Why is this and what can I do to try to get around the problem?

I've got a large codebase which I'd like to expose to plugin authors to allow them to use VB.Net Express to code plugins for a server app, which is not available to them. My problem is that even with obfuscation, I'd rather not distribute the complete app and/or dlls, as even with obfuscation peeling apart a .NET assembly and puzzling out code is relatively easy to do. I'm interested in this because the licensor I obtain the code from requires me to protect IP and assets and while distributing .NET apps opens up the app to disassembly, keeping the server app private and allowing users to utilize a skeleton dll to code against is a happy medium.
What I'm looking for is some way or a utility to go through my server app source code and create a codeless version of the app which only contains method and property signatures.The intent is to provide a stub .NET dll for them to add as a reference and code against as if they were directly interacting with the server, without actually providing the server code to them, compiled or not. I can of course do this by hand but there are over 90 classes and hundreds of thousands of lines of code I'd rather not spend a week hand tweaking. Also, this presents a problem whenever new methods or code are added to the project. Finally, two separate projects is an even worse scenario.Because people will post suggestions that have little or nothing to do with the question, here's a short, clear example. I want to turn this class:
Public Class MyServer
Public ReadOnly Property Name() As String
Get
Return "Whatever"
