i am trying to complete a project. My task is to read large TXT files (300 files, 2.2 GB in total) read the customers inside, perform some data calculation and write each customer data to a separate txt file.
I made a code in VB6, it runs fine, however it takes 8 days to run on a quadcore processor, utilizing 20-30% of the CPU. Now I upgraded the code and am running on VB.NET 2008, the latest version. The speed still remains the same, and the CPU usage is also about the same.
Anyway I can make this process faster. I have a quadcore PC with 8GB of ram, possible to maybe make VB utilize all the CPU say 100%? so it executes atleast 2 to 3 times faster.
For some reason, .NET applications that I've written seem to have issues if they're launched when Windows starts (by being in the Startup folder for instance). An application that can finish in 3/10 of a second if one launches it normally may seriously take 45-90 seconds to finish if it was launched when Windows loads. Even if I just manually wait 30 seconds after login and launch the program, it'll complete virtually instantly while a copy launched at startup is still struggling along, so it isn't just that Windows is still loading...this continues AFTER that finishes and all HDD activity stops.Writing something to disk using an IO.anything goes at about 20KB/s during this event.
I have Created an windows Application in .Net, when i start it first time, it takes lots of time to load. however i have used StoredProcedures to get data from database.So is there any technique to decrease the load time of an application?

How do I speed up a download / increase bandwidth usage? I tried using more threads but the speed caps at 2 threads.how do download accelerators like internet download manager speed the download so much?
I have created a code in VB.NET to read data from text files. Data is read from a list of files, where each file is changed using a for loop. Data is written to a new text files. Each file is read one by one and written in the same way. Now, my speed of execution is very slow. I am using a Quadcore processor with only 20-30% of CPU utilization when my code runs. Is there anyway I can increase the speed of reading and writing? To read only 125 files it takes 10 minutes or more, which is very slow indeed, because in the end I need to read thousands of files and write them. Each file is approxiamately 30-50kb.
Here is my code.
Public Sub ReadRMRDataFileIntoTextFiles() 'Read in the customerids once up front Dim customerids As Collections.Generic.List(Of String)

We are four in a team using a data entry application created using VB and MS Access as backend DB. The application is installed on all our PCs, but uses my PC as server. We enter data at same time. The application has been slow since we started using it. We were advised to increase the internet bandwidth, which we doubled, but the application is still slow. What can be done to increase the speed of the application to make work move faster?
I'm going to create some command line tools that make use of some large library DLL's. For security reasons I plan to embed the DLL's in the command line's EXE. Example:Suppose the CL's (command line tool) functionality is to just copy a file from A to B. The procedure to do this is included in a 100MB library DLL. If I would just take out the lines of code from the DLL and paste them in the CL's code then the CL would only be 10Kb.But I don't want to do that, so I embed the full library in the CL's EXE, which will make it 101MB in size.I once read somewhere (cannot remember where) that Windows would only use the part of the EXE that's actually used. So if that's true then it shouldn't matter if the EXE size is 10Kb, 100MB or 1GB.I own the code of the DLL, so if the best solution is to not include the whole DLL but just only link to or include those code files, of the DLL project, that are used by the CL then I will go that way.will the 10Kb CL run faster and consume less memory than the 101MB CL?
"Does the selection type of variables speed up the code execution in VB.NET?"For example, I have two same exactly same projects where the first project is running with all Single variables and the other project which running with all Double variables.Is there any difference in term of the speed of code execution?This is because I'm working on a project which is very critical in term of the speed of execution. However, I'm using Double variables for most part of the code.
I have a per-call WCF service that serves a number of clients. I'm looking to speed up the services by running some background processes so they don't block or slow down the main function of the services.
One example is that the main function needs to return a set of data, while the background thread needs to record some statistics based on the parameter(s).
Code:
Public Function GetAccountDetails(id As Integer) As AccountDetails Dim retVal As New AccountDetails Dim a As New Accounts
[Code]....
If I use this background thread to record the statistic it doesn't block the main thread from returning the data to the client.
It's been working well in test scenarios, but my question is, are there any dangers with leaving this thread to execute without Joining it before returning the data to the client? Could there potentially be any loss of statistic data? Could there be potential memory problems on the server side?
I'm trying to code an 'increase' button to prompt a user to input a rate by which to increase select prices in an array.It should request the increased rate, then request a number from one to five, representing which price in the array to increase.Then, if 'increase' button is selected again and another number from one to five is chosen, then that element should be increased.It's working, but all the numbers in the array are changed. And, when I hit the increase button again, the array is repopulated below the first price increases instead of only replacing the designated price.
'declare 5 element array of prices Dim prices() As Double = {12.2, 8.5, 12, 50, 2.4} Dim rateIncrease As Decimal Dim isConverted As Boolean
How do i exactly check internet connection speed.I have searched around google and found out a method w/c will Download a file like 1mb size, then it will calculate the speed.
I have a codes that calculates DownLoad speed and UpLoad speed kb/s. I would like to implement this kind. I also want to put such kind of graph. Any article or links where can I start building my own like that.
I'm having trouble inputting data in to an array. The first input is fine but after that it just overwrites the first input. i tried to write it so that it would increase the array index by one each time but it hasn't worked.[code]
I'm in the process of making a barcode printing program for my job. The barcode is printed by printing text using font "WASP 39 LC". I have it automatically determining the correct font size of the text so that it will stretch from the left edge to the right edge, but the barcode isn't very wide (or tall), It's only about a centimeter tall (when printing a 9-digit number).
this is what I want it to do. On the label, I put a little image (a question mark icon). When hovered, a bigger image would appear. But the problem is, some other "labels" is going on top of the bigger image. And also, the bigger image, gets cropped when it reaches the border of "groupbox"
