I need to perform a huge amount of registry read operations, and I'm trying to figure out a way to make each read operation faster than using My.Computer.Registry.
If I used APIs directly to do it, it should be faster, right?
I am working on a small program to teach myself how to use timers, and I would like to know if there is a way to make the timer control faster.I set the Interval property to 1 and it is to slow for what I am trying to do.(All I am trying to do is loop a button left to right, right to leftand so on in a Panel)
View 39 RepliesI have a windows form which to summarize lets the user open a file containing 32 bit hashes, then search for one of them. The hash is then converted to its string representation. The application is giving the results I would expect but I'd like to make it execute faster than it does now; some files can be pretty big > 100 MB.
I'm doing the file read using a BackgroundWorker object to display progress updates and ensure that the UI is available during the process. But for that i need to add a System.Threading.Sleep(1) instruction in the loop; otherwise the application freezes with big files. And System.Threading.Sleep(1) creates a noticeable lag. Any suggestions on how to make searches fast without freezing the UI? Getting speeds comparable to hex editor programs for example.

View 2 RepliesBasically what i need is for something to look at the items in a list box then compare it to the contents that is in the database. The issue is that the listbox can have more than one of the same item. For instance, LstBox_Order.items(0) could be the same at any position in the listbox. This code works, but it is slow if there is like 10 or more items added.

View 12 RepliesI have a function that I use quite a bit that I wrote more than 2 years ago. It works fine but recently I saw how it can use up a good deal of time under certain condition. Here's some code that uses the function SelectValue The function works so that if you had N which you plug into the function rising continuously while SelectLimit was set to 255 then SelectValue would match N until N reached 256. SelectValue would start to descend to 0 until it reached 0 and then it would again ascend to 255 and the process would repeat. So SelectValue(255, 255) would return 255 and SelectValue(256, 255) would return 254. SelectValue(257, 255) would return 253.

The function works exactly as I want it to but if one of you knows a way to write this so that it will process faster then you can let me know. I get a result for processing time of 6.11 seconds on my computer for the above code.

View 14 RepliesOK, I've been searching for hours trying to find the best way to fill a listview from a comma delimited file but have come up empty handed so far. Currently I am using code I found on the NET, which works, but it is EXTREMELY slow. As a test, I created a file with 5,000 rows, and 10 columns. The column layout is as follows:123,NAME,NAME,NAME,NAME,0.00,NAME,YEAR,NAME,1
Dim ofd As New StreamReader(".dataCardData.bct")
Try
Using reader As New Microsoft.VisualBasic.FileIO.TextFieldParser(".dataCardData.bct")
reader.TextFieldType = FileIO.FieldType.Delimited
reader.SetDelimiters(",")
[Code]...
The code I am currently using appears to be loading the file and somewhat simultaneously filling the listview at the same time. I feel that I should load the entire file into an array or arraylist and the send the array or arraylist to the listview. However, if this is the best way to do it, I have not been able to find any examples of how to do this.
I have an array of approximately 1000 classes. All of these classes must have one of their properties changed to the same value. I need this to be as optimized and fast as possible.

View 1 RepliesSuppose you have an array with 10.000.000 elements filled with values between 1 and 10, and you need to count how many fives it contains, something like:
Dim RandList As New List(Of Integer)
Dim r As New Random
Dim Counter As Integer = 0
For i As Integer = 1 To 10000000
RandList.Add(r.Next(1, 10))
[Code] .....
Here I got 2 problems, both versions are returning different values at each call with the same array, and the sequential ForEach is being executed much more faster than the parallel.
