My.application.networkavailabilitychanged Takes Forever To Fire
Feb 9, 2010
I am working with the my.application partial class and I was trying to launch some events off of the networkavailabilitychanged event and what I have noticed is that it takes 9-10 seconds to fire that event if I disable wi-fi and pull the LAN cable on my development machine. What I would like to do is significantly shorten this duration. Something like 100ms would be great. If no, what else can I poke for a network status that will handle this response time?

Ok, this might be something stupid that im not doing right, but here is my problem. Im moving from my 1st form, a small window, into my second form, that is full screen, but it takes like 4-5 seconds to load the full form. It sucks because during this 4-5 second load time, parts of the form at transparent and it just look bad. I think it might be because i have around 35 labels and a few other objects on the form. Does anyone know a way to make this not happen? Im in VB08.

This loop takes forever to run as the amount of items in the loop approach anything close to and over 1,000, close to like 10 minutes. This needs to run fast for amounts all the way up to like 30-40 thousand.

I am creating a WPF Application that uses Fluent library.
On my computer with Windows 7, 2GB RAM and AMD Triple Core processor, after double clicking on the program icon, The Splash image shows after about 1-2 seconds.
But on my brother's old computer with Windows XP, 512MB RAM and Intel Celeron 2.0 GHz Processor (Single core), after double clicking on the program icon, First, a process called PresentationFontCache.exe runs and it uses almost 100% of CPU for some seconds. And Total time is needed for displaying the initial Splash image is almost 30 seconds (or more).
I don't want that some users have to wait 30 seconds for displaying splash image and about 7-8 seconds for loading application. (my application load process takes 7-8 seconds)

I wrote an app in Visual Studio and is about 20k+ lines, but I don't know why it takes so long to start up. I have a splash screen just to test it to see if the program is working, and it is, but I have to wait for so long for the app to actually get to the start up form. A splash screen for this app isn't ideal, but was only using a splash screen for test purposes.

For a class assignment I created an application that takes grades from the user via input box and adds them to an array called grades. Here is some of the code.
vb.net
Option Strict On
Option Explicit On
Option Infer Off
[Code]...
My problem is that the variable x is an integer and the user input from the InputBox is a string so I get the error: "Option Strict On disallows implicit conversion from 'String' to 'Integer'.I've already submitted this assignment with out the first three lines of code (which allows the code to run flawlessly), but I would like to know how to get around the error while still using the Option Strict On parameter. I am aware of the ToString method but I am not sure of how to use it here or even if it will work here. I've tried to use in a few variations but none worked.

I'm a relatively seasoned VB (COM) vet but this is my first VB.Net application and as is my luck a web services application feeding off a site that I can't publicly mention nor can I post any code that may expose the site.
So, here's the problem. I have written a simple form and have 2 buttons. 1 button simply asks the webservice for it's version. This works no problem. I was able to load the web reference using their supplied WSDL file for this "version" class. Now that I have that working I think "GREAT, that was straight forward. I have my credentials, urls, etc working, the rest of this should be just as straight forward." (See where I jinxed myself here?)
Anyway, I move onto the next WSDL and set of classes and get that reference added no problem. (Man that took a LONG time, like 20 minutes.) I then build my "Get my order data" code syntaxes on the prescribed exposed classes and run my project just to see what errors I get. The "run" process takes almost 45 minutes to an hour..... It's as if the app is getting the WSDL set all over again but doing it over and over..... I have no clue what's going on.
I've tried to disable all the Windows 7 "potential" issues, UAC, firewall, etc, but these changes don't help. Anti virus, spyware, etc all these are off and no difference. I'm running VS2008 as an Admin, right click "run as admin", and have complete control over this machine. Any ideas, suggestions, etc are VERY welcome and I am happy to expose as much of this application as I can providing I can stay with in the rules of the confidentiality contract.

I made two applications the first one calls the other. But the other application takes time to load. Even on a fast Pc. So i was thinking of adding a loading form to it. For example when the other application is done loading the loading form goes away.

I created for my app unhandled exception it ask the if they want it to "phone home" and report the problem. I want to test the code, but I can't, since if I try to fire an unhandled exception when debuging, by typing Throw New Exception() at a point in the code, the debuger just stops the code there, not letting the UnhandledException code run.

I have a program that reads data from a scanner via the serial port.This program works fine on Windows XP.We have a terminal server set up running Windows Server 2008.I run HyperTerminal on our test terminal, it connects and reads the scanner data fine through COM1.I run my app on that same test terminal and get nothing when I scan.My app connects to COM1 without errors and disconnects without errors.BUT, the DataRecieved event is NEVER getting fired.Neither is the ErrorReceived event.I have played with the Handshaking, with the RecievedBytesThreshhold and pretty much every setup setting I found.Set it up exactly like the settings on Hyperterminal.I have even tried starting a timer on a different thread to call ReadByte every second to try to KICK this thing into doing SOMETHING.Nothing has worked.
I have been trying to fix this for an entire day now.Added events to my class trying to see EVERYTHING that is going on. All I know is, it connects to the port and it disconnects from the port correctly but nothing happens in between.No data when I scan.No event fired at all between connecting to and disconnecting from the port.I have also downloaded other's simple serial communications applications.Nothing in .NET works.[code]

I wrote a simple auto login script to update my IP address on a certain website. Something really strange is happening now though. The first time I run the program, nothing happens. However, the second time I run the program, that instance will work fine. Then I look in task manager, and the first program is still running, using a whopping 50% of my CPU. I believe VB may be blocking off memory or something, as when two instances are running each is using around 25% of CPU. Then after the second one successfully completes, the first starts to use 50% again.
Here's my code below:
Option Strict Off
Public Class frmTest
Private Sub frmTest_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

A couple days, I figured up a working program and it was def. faster than what we needed. Now, adding a couple more loops, the program barely uses any memory, but the cpu used spikes up to 90+ and just letting it sit doesn't help.I tried taking out the couple loops I put in, but it does not revert back to being fast. It's nothing big, but since dealing with 1000+ excel files a day, I'd rather not do that by hand.
how many infinite loops vb.net can support without dragging down the system? I know, infinite loops are poor design, but it works.
