I have finally figured out how to download a file with background worker and downloader. Now the form does not freeze.. I have only one problem left now... How do I get the progress bar to increment in tandem with the data flow? I have listed my full code below. Towards the bottom where the DoWork() sub resides, I am just a few lines short of this year long goal.

I've create my program before in Windowx XP ir required 1:37 seconds to finish the Genetic Algorithm but after I moved to Windows 7 64 bit and trying to used the 64 bits compiled version it runs much more slowly, it could take 5 minutes more, I've tried to change to 32 bit compiled version it run more faster than 64 bits but still slower than Windows XP it takes about 2:01. Is there something I missed in the compiling for 64 bits, or maybe the VS 2008 still not compatible with Windows 7.
View 3 RepliesI have written a dll in vb.net that does a lot of number crunching and iteration and takes about 2 1/2 minutes to complete, so I would like to make the progress available to the calling application.
At present I have created a couple of public variables in the dll called sngProgress and intIteration and update them in various loops in the dll.
In my calling applications I have a text box and a progess bar on a form but I cant see a logical way of updating them during the lifetime of the instance of the dll.
The call to the public fucnction in the dll cannot be in a loop otherwise it would be called multiple times so a doEvents call does not seem feasible.
i have a .txt file containing 27,607 words, 1 per line, and i need my program to slowly read through and put it into a textbox/label. It only needs to read in order, not randomly or anything. It needs 2 be slow enough that I can read every word being shown, and if possible it would be nice to be able to change the speed but it is not needed.
Public Class Form1
Dim FILE_NAME As String = "C:My DocumentsWordList.txt"
Dim objReader As New System.IO.StreamReader(FILE_NAME)
[code]....
This is what i tried and all this does is displays 2 words in the middle of the file, then form goes white for about 5 seconds and then the last word in the file shows up and the program remains white. When i try with a txtbox only the last word is displayed.
I have such a bad habbit of cramming all my code into one form. But i dont know when i should write a class. or dont really understand how to return the information back to form1. when should i even use a class? for example i have some code here

I am trying to implement a BGW and want to report progress to a progress bar for my TextFieldParser program, sometimes if your opening very large files it takes a while and I would like the user to be able to see the progress and have some interaction so they know the program is still running I am a little hung up on what to in the reportprogress
I have:
worker.ReportProgress(0, myReader.ReadFields())
and its not doing anything, I didnt expect it too since ReadFields is an array

I have a form and some controls as dropdown and textboxes..
The situation is that when the form loads, i want the value in textbox to be incremented, everytime it loads..
This is something i tried.. I get the value '1' everytime !! It shows no sign of increment..
However, i also want it in the format 0001,0002 if possible..I tried something like this..
Private Sub Order_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
textBox1.ReadOnly = True

Im trying to change or increment the month value of the datetimepicker using a command button. I tried to use the sample code from MSDN site but I was only able to increment once. I want to increment the value of the month everytime you click the command button. Do I need to use a loop statement? If so, how do I do that? I used this code below which can only increment or change the month value once but when you click the button again, no changes will be shown.
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
'DateTimePicker2.Value = New DateTime(2001, 10, 20)
DateTimePicker2.Value = New DateTime(DateTimePicker2.Value.Year, DateTimePicker1.Value.Month + 1, DateTimePicker2.Value.Day)

So in this program that I've made, I have 5 tabs. One of them uses this chart control for .NET ver 3.5 that I downloaded from the Microsoft website. The issue is, though, that when I start the program, everything is fine until I click on the tab with the 3 charts on it. The tab freezes a little bit, and it takes a few seconds to load the charts. After this initial hiccup everything is fine, but I've tested this on three computers now and it happens to all of them. Anyone know what I can do to make these charts load faster or smoother? This is quite a roadblock.because otherwise I'd be done I've been working on this project in VB.NET for the past 3 weeks and it's my first time using the language. So far every single one of my questions on here has been answered and all within a day or two
View 5 RepliesI am working with serial port communications. I have very fast and continuous data on my serial port. I have a program to read data from serial port. I have comport.Datareceived event in my program to receive data. Now, the problem is there is data going every 100ms to comport. Will my comport.DataReceived event will receive also with that fast? Now,let's say there is data on comport and if I don't read it what happens to the data? The problem I'm facing is my dataReceived event is getting very slow after some time.If I stop sending data to my com, still my datareceiving program is receiving. That means it is not as fast as sending data.If I keep sending data from 4 to 5 days and coz my datareceived event is not that fast as sending, I am getting data very slowly and some times I am getting MemoryOutofRange Exception.

View 4 RepliesBackground :While running benchmark tests this morning, my colleagues and I discovered some strange things concerning performance of C# code vs. VB.NET code.We started out comparing C# vs. Delphi Prism calculating prime numbers, and found that Prism was about 30% faster. I figured CodeGear optimized code more when generating IL (the exe was about twice as big as C#'s and had all sorts of different IL in it.)
I decided to write a test in VB.NET as well, assuming that Microsoft's compilers would end up writing essentially the same IL for each language. However, the result there was more shocking: the code ran more than three times slower on C# than VB with the same operation! The generated IL was different, but not extremely so, and I'm not good enough at reading it to understand the differences.
Benchmarks I've included the code for each below. On my machine, VB finds 348513 primes in about 6.36 seconds. C# finds the same number of primes in 21.76 seconds.
Computer Specs and Notes
Intel Core 2 Quad 6600 @ 2.4Ghz
Every machine I've tested on there is a noticeable difference in the benchmark results between C# and VB.NET.Both of the console applications were compiled in Release mode, but otherwise no project settings were changed from the defaults generated by Visual Studio 2008.

I have a website(asp.net) which displays ssrs reports. Howevery everytime that I try to run the report from the website it takes about 2 min to load, but if I click on the report again , it will load up in seconds. I have tried to run a query that is used by the report and I get the results in second as well.

I have gone through to solutions provided here on stackoverflow but still had no luck.
I created a program that has 11 threads running simultaneously.Each thread runs a stopwatch and measures the amount of time that passes between the Start and Stop.There is no code between the start and stop, so most often, the result is 0 milliseconds.I noticed that INITIALLY, after a few minutes, the program would slow and the output to the RichTextBox would become disjointed.So, every two minutes, I have a timer execute and end the threads and restart them all.This seemed to help, however, after about an hour and a half, the program becomes more sluggish, evident in the stopwatches recording more instances over 0 milliseconds.Does this have to do with 'garbage collection' and is that even possible in VB .NET (I thought C only had that), or perhaps memory management?
