[2005] Working Of Friend Class With Public Methods?
Feb 27, 2009I understand how the class modifiers work like public, private, protected, friend and protect friend. They are pretty straight forward. However my question is, if I have a class is marked as friend, what should the properties and methods be marked as? Friend or public? Does it matter? I just want my classes at the lowest exposure level that will let my program work properly and that is friend. If I understand correctly, the public properties of a friend class are available to all members of the assembly. Wouldn't that be the same access level if the properties were all friend properties?The reason that I ask is that using the autocomplete feature to make new properties (type property and hit tab) it creates the new properties with the public attribute.

Threads In .vb Class Not Working For Web App
Feb 11, 2010I have a web app that I'm writing in asp.net, with vb code behind. The threads were working well when I had all my code in the aspx.vb code behind files, but after I moved the code into a seperate Class.vb file, the threads don't seem to be working in parallel any more. Below is a small section of my code.
It used to be that when the "botThread.Start()" method was called, the page would redirect to success.aspx, and work on the SQL query (RunBots()) thread in the background. Now when botThread.Start() is called, the page doesn't redirect to success.aspx until AFTER the RunBots() sub has been completed.

View 6 RepliesVS 2010 See If The Microphone On A PC Is Working Correctly By Utilizing The SpeechRecognitionEngine Class?
Nov 15, 2011I'm trying to see if the microphone on a PC is working correctly by utilizing the SpeechRecognitionEngine class.I'm using the following
VB.NET
Dim RecognitionEngine As New SpeechRecognitionEngine(New CultureInfo("en-US"))
'Dim synth As New SpeechSynthesizer
'synth.SpeakAsync("Microphone")
[code]....
When I run this code, the microphone runs until it detects a sound. If the room is silent, it never stops. At least so much as I can tell so far.But I need a way to detect when it can't detect a sound within a specified interval.I looked on MSDN and all I could find was a property called, BabbleTime. I can specify a TimeSpan that will time out the speech recognition, but from that, I can't determine if it was the timeout that caused the code to continue or if it detected sound.
Right-Click Not Working In VB 2005?
Apr 25, 2011I should mention I am developing this in SharpDevelop, so if it's a bug with this software then I'll take this up with them.
So I am having issues with trying to get a right-mouse click to work. I have a grid of 30 buttons and I need to right-click to enable a button and left-click disable. I have surfed all over the internet trying to find the answer and the closest I have come to it is it detecting a left-click, but never right.
Sub Button1Click(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Button1.Click
DataGridView1.CurrentCell = datagridview1.Rows(0).Cells(0)

As you can understand, I am having a lot of frustration with this. It just seems that I can't get it to work. I've scoured the internet looking for a solution without avail.

VS 2005 RaiseEvent Not Working?
Apr 30, 2011I'm having an issue with rasing an event. In my application I have a form and within that form I create an instance of a class (clsUsage). Within clsUsage I create an instance of clsUser which does several checks form permissions and other things. What I want is for clsUser to send status updates to clsUsage. ClsUser will be a dll but for now I've got it as a separate project in my solution. The RaiseEvent in clsUser seems to execute but the proc in clsUser that handles the event does not execute. I'm wondering if this is threading issue.

VS 2005 Importing Data Not Working?
Mar 16, 2011I have a table in my database. I have an import routine which reads rows from and XML file. It first loops through my existing table to see if the row exists using a date and store code column as a unique id. It all works fine until this senario occurs.First file is read in and a new row is added for 01/03/2011, store code 100. The second file is read in which also has a row with 01/03/2011, store code 100. But when I loop through it does not find the row I just added so it adds it again.The only solution I can think of is to re-populate the local table everytime I add a new row but this will have a massive amount of over heads.If I add a row to an existing dataset surely if I loop through that dataset I should come across it.
