View 1 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.
I currently have a directory with 98,000 individual archive transaction files. I need to search those files for user input strings and have the option to open the files as it finds them or at the end of the search. I'm using Notepad++ currently and, while functional, it's quite slow. I thought about writing my own, but I am only familiar with .NET and I'm a beginner. Also, I'm not sure how efficient that would be compared to NP++.
This tool would be used again and again so the dev time would definitely be worth it if it came to that. Is there some other tool out there that's already developed that would accomplish this?

View 6 RepliesIf e.CommandLine.Count > 0 Then
Dim IncomingCommand As String = e.CommandLine.Item(0).ToString
If IncomingCommand.Substring(0, 2) = "-1" Then
form1.close()
End If
End If
I am trying to make the program close if the -1 string is sent with the program. See my installer allows for me to run certain programs before it actually installs, but it doesn't shut down copies of the program itself. So I have a next startup instance set to shut the program down if the -1 is received. But if the program is not running it starts up instead. This is not desired. form1.close doesn't work. e.cancel = true doesn't work, etc etc. What can I do to make the program not start during this instance.

View 2 RepliesI've been developing a simple virus scanner and it works by reading the hex code of a file and comparing it to signatures from a database. Anyway, the only thing slowing it down is how it reads the hex. This is the hex reading part of my code so far:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LoadFile.Click
Dim ArrayHold() As Byte
Dim Index As Integer = 0
Dim Str As New StringBuilder

What I need is to highlight multiple matches within some portion of text as the user types a search pattern. Right now I'm using a RichTextBox to highlight text. The highlighting takes place if a user changes the search pattern and naturally it happens with each key press. It works, but I'm experiencing a performance issues. If the text is large enough the highlighting takes too long (up to several seconds).
Facing that I tried to launch the highlighting procedure in a different thread aborting it and launching it again if the search pattern was changed during the highlighting but still I'm not satisfied with performance. Now I'm asking if there some other control I could use to speed up the process?

View 1 RepliesOK. I am making application for copying. Problem is that every time application wants to write it first tries to write via fast IO and get response that it isn't allowed and then it writes a file (i am assuming without fast i/o). I have no idea what fast i/o is (i know io is input output -> read write). So I can assume that it is handled by class that I am using to write. I am using System.IO.FileStream and its functions Read and Write. Is there any other class that I can use witch will allow Fast IO or disable trying it in first place (I would like the first solution)? Or should I do something else?
View 6 RepliesI need to transfer files from one server to multiple cients (using the internet) in the fastest possible way in .NET .

I have written a logon script using Visual Basic Studio Express 10 and it simply installs printers and adds network shared drives. It does look at the users Active Directory group and add drives / printers. But on occasion it doesn't install the drives or printers.
I've placed a copy of the logon exe on the desktop and if the user finds they are missing drives etc they click on this and add them again. This has never failed so I'm curious as to why exactly the same exe would fail at logon? Is it something to do with speed of the computer or a time out somewhere? A frustrating problem!
