View 2 Repliesi 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.

View 1 RepliesI 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?
View 1 RepliesI'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

View 4 RepliesI have an application built in vs 2008. The main form is a MDI form with a datagrid for record selection. When the user double clicks on the datagrid it opens a child form with the selected information. the problem I'm having is once the child form appears if I move the mouse up and down I can see the cursor moving as if I was holding the mouse button down on the datagrid and selecting/deselecting multiple records. It will do this until I click on the child form. I've tried setting the focus to the child form but to no avail. It's almost as if the MDI form doesn't realize the mouse button has been released until I click on the child form.
