How to: Search files from a certain directory with Progressbar + Backgroundworker

Tue, 31 Oct 2017 15:25:17 +0000

Hello Everyone, Admin. I'm new to this Forum and i want to ask how to search files from a certain directory with progressbar & background worker?Â

Code: (from the Admin-(Brandonio)) :
----------------------------------------------------------------------------------------------------------

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Â Â Â Â BackgroundWorker1.RunWorkerAsync()

Â Â End Sub

Â Â Private Sub BackgroundWorker1_DoWork(ByVal sender As System.Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles BackgroundWorker1.DoWork

Â Â Â Â Dim directory = "Path"
Â Â Â Â Dim files() As System.IO.FileInfo
Â Â Â Â Dim dirinfo As New System.IO.DirectoryInfo(directory)
Â Â Â Â files = dirinfo.GetFiles("*", IO.SearchOption.AllDirectories)
Â Â Â Â For Each file In files
Â Â Â Â Â Â ListBox1.Items.Add(file)
Â Â Â Â Next

Â Â End Sub

----------------------------------------------------------------------------------------------------------
But whenever i click the button, i get an error saying :Â Cross-thread operation not valid: Control 'ListBox1' accessed from a thread other than the thread it was created on.
----------------------------------------------------------------------------------------------------------
I'm new in VB.NET and i'm making an application that cleans up the Temporary folder.
Thank you. and uh, i like this forum.

Krypton Toolkit Download

Tue, 29 Mar 2016 03:55:55 +0000

It has come to my attention that the Krypton Toolkit (ComponentFactory) is no longer available for download. Instead, theÂ pageÂ simply contains no download link.

In the past, certain components of the software were free, while others were free for a limited number of days. In order to continue using the software indefinitely, a license key is needed.

Since the files are no longer available from the ComponentFactory webpage, here is the link to 4.4

(Apologies for the file provider.. it's a pretty big file)

It was pointed out by a viewer of my original RunAsAdmin video that the files for RunAsAdmin have seemed to disappear from the web. I am putting them here for public access. If you are a viewer of the aforementioned video, the file that is of interest to you is "RunAsAdmin.zip", available here:
RunAsAdmin.zip (Size: 21.46 KB / Downloads: 2434)

If you are a developer, you may download the source package here:

Using a string as an alias/nickname

Thu, 04 Jun 2015 17:12:11 +0000

So part of the application I am building is a user blog, where the user can submit new blog entries or view previous entries. I've managed to write to/read the blog entry to and from a text file, with a 9 digit date format in front of the entry.

The problem I am having is that when I am loading the previous entries into a comboBox, it is loading all the text from the blog into each item of the comboBox.

What I want to do is load the date of the blog into the comboBox only, and when the user clicks on said date the entire blog text file is loaded into a textBox.

In the code below, I really need the blogAlias string to act as alias/nickname in the comboBox for the actual blog text. But I can't figure out how to do it.

Code:
'Fill comboBox with array of previous blog entries

While j < blogLineCount

 Â  Â  Â  Â  Â  blogAlias = blogArray(j).Substring(1,9)

 Â  Â  Â  Â  Â  comboBox1.Items.Add(blogArray(j))

 Â  Â  Â  Â  Â  j = j + 1

End While

Read all lines from multiple text files.

Hello. Nice site.

I just recently viewed on of the BP youtube tutorials on how to get all the files from a certain directory.

I was wondering if there was a way of amending it so that every line of every text file in a directory could be stored into an array?

Thanks.
