The system cannot find the reference specified for an assembly - vb.net

I have a VB.NET solution which have a few projects and a 'References' folder in the root directory.
Now I want to add a new dll reference to one of the projects from this References folder but getting the following message:
The system cannot find the reference specified
How can this be solved?

I encountered this many times. Here I was trying to execute a jar file when a picturebox was clicked. I added my jar to my resources :
Private Sub PictureBox9_Click(sender As Object, e As System.EventArgs) Handles _PictureBox9.Click
Dim dir As String = My.Computer.FileSystem.SpecialDirectories.Temp
Dim filename As String = dir + "minecraft.jar" 'Look Below
IO.File.WriteAllBytes(filename, My.Resources.minecraft)
Process.Start(My.Computer.FileSystem.SpecialDirectories.Temp & "minecraft.jar")
End Sub
The following worked for other programs though, but not minecraft, :
Private Sub Panel9_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Panel9.Click
proc = Process.Start("vbexpress.exe", "")
End Sub
*proc was a New System.Diagnostics.Process()
But for actual files, you have manually lure them out of their location.
So I did Me.Resources.1234.png which saved me writing the directory. But this still did not work with minecraft, so I kept that long paragraph about in place.

How can I move a certain file extension into one folder with VB

I am new to VB and would like to create a software that moves a certain file extension into a single folder. I have already built the code that creates a folder on the desktop when clicking the button although after that runs I need to compile a certain file such as (.png) into the folder in created.
This code creates two buttons that when pressed creates a folder called "Pictures" and "Shortcuts".
How would I go about moving all .png files from the desktop into the pictures folder?
Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
My.Computer.FileSystem.CreateDirectory(
"C:\Users\bj\Desktop\Pictures")
MessageBox.Show("Pictures Compiled And Cleaned")
End Sub
Private Sub Button1_Click_1(sender As Object, e As EventArgs) Handles Button1.Click
My.Computer.FileSystem.CreateDirectory(
"C:\Users\bj\Desktop\Shortcuts")
MessageBox.Show("Shortcuts Compiled And Cleaned")
End Sub
End Class
We'll start simple. This command will generate an array of all the PNG files' paths on the desktop
Dim filePaths = Io.Directory.GetFiles("C:\Users\bj\Desktop\", "*.png")
We can loop through this array and act on each filepath:
For Each filePath in filePaths
Dim filename = Io.Path.GetFilename(filepath)
Dim newPath = IO.Path.Combine("C:\Users\bj\Desktop\Pictures", filename)
IO.File.Move(filePath, newPath)
Next filePath
We have to pull the filename off the path and put it into a new path, then move from old to new. This I also how you rename files; have a new name in the same folder and use Move. Always use the Path class to cut and combine file paths

vb.net ~ How to add folder names from a directory to a list box

I'm trying to add folder names from within a directpory specified by the user to a list box. I have tried a few solutions, but can't seem to add any items. Most recently I tried:
For Each folder As String In System.IO.Path.GetDirectoryName("D:\")
ListBox1.Items.Add(folder)
Next
The form was built using VB in VB Studio Express 2013. There were no errors when running the program.
If anyone can point me in the right direction, then please help!
If you want to have a list of Directories you need to call Directory.GetDirectories(path), not Path.GetDirectoryName(path) that, in your case returns just null (passing the root directory of a drive)
For Each folder As String In System.IO.Directory.GetDirectories("D:\")
ListBox1.Items.Add(folder)
Next
if you want to show only the folder name and not the full path, just use
For Each folder As String In System.IO.Directory.GetDirectories("D:\")
ListBox1.Items.Add(Path.GetFileName(folder))
Next
Yes, I know, it seems wrong to ask for GetFileName over a folder name, but passing a full path to GetFileName returns just the folder without the path.

Creating an application that moves a collection files from one place to another using VB

So this is an application I have to create that moves files from one directory to another, both directories being specified by the user. It seems easy enough, but the problem is that there are millions of files that have to be searched through. These files are all named with 8 digits for example, "98938495.crt". The directory where all these files are has multiple folders. These folders within the main one are named with the first two digits of all the files that are in the folder. And then in that folder there are roughly ten zipped folders that contain 100,000 files each. The name of those folders are the minimum and maximum names of the files. For example, I go into the main folder, then click on the "90xx" folder. In that one there are 10 zipped folders which are named with the minimum and maximum names of the files, like "90000000_90099999.zip". That zip folder contains 100000 files. Now, this app is supposed to find all the files that the user inputs and then move them to a folder specified by the user. I have posted my code so far below, any help at all is greatly appreciate!!
FYI: The STID is the name of the file.
GUI for the app
Edit: I realized there is no way to answer this question because there really isn't a question, just a broken app. Basically, how do i search for the items in the directory and then copy them into a new directory?

In answer to the .ZIP unpacking, use the System.IO.Packaging (more can be found at CodeProject - Zip Files Easy)
Don't you think using a database would be easier to store that data?

What is the file path, as a string, of a file in the application's resources?

The reason I ask is that I want to print, at run-time, a file in the application's resources, like this:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim printProcess As New Process
printProcess.StartInfo.CreateNoWindow = True
printProcess.StartInfo.FileName = "C:\Users\Geoffrey van Wyk\Documents\Countdown_Timer_Help.rtf"
printProcess.StartInfo.FileName = My.Resources.Countdown_Timer_Help
printProcess.StartInfo.Verb = "Print"
printProcess.Start()
End Sub
When I use "C:\Users\Geoffrey van Wyk\Documents\Countdown_Timer_Help.rtf" as the argument of FileName, it works. But when I use My.Resources.Countdown_Timer_Help, it says it cannot find the file.
No you didn't get it, that file will only be present on your dev machine. After you deploy your program, the file will be embedded in your program and cannot be printed. You'll have to write the code that saves the file from the resource to disk, then prints it. For example:
Private Sub btnPrint_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPrint.Click
Dim path As String = Application.UserAppDataPath
path = System.IO.Path.Combine(path, "Help.rtf")
System.IO.File.WriteAllText(path, My.Resources.Countdown_Timer_Help)
Dim printProcess As New Process
printProcess.StartInfo.CreateNoWindow = True
printProcess.StartInfo.FileName = path
printProcess.StartInfo.Verb = "Print"
printProcess.Start()
End Sub
Given that you have to save the resource to a file, it probably makes more sense to simply deploy the file with your app instead of embedding it as a resource and writing it to disk over and over again. Use Application.ExecutablePath to locate the file. To make that work at debug time you have to copy the file to bin\Debug. Do so by adding the file to your project with Project + Add Existing Item and setting the Copy to Output Directory property to Copy if Newer.
OK, I got it.
System.IO.Path.GetFullPath(Application.StartupPath & "\..\..\Resources\") & "Countdown_Timer_Help.rtf"

resource file in VB.NET

How can I use a .exe file in my resources folder? I want to copy the file in the resource folder to another folder.
tried this
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
If (Directory.Exists("Files")) Then
Else
End If
Directory.CreateDirectory("Files")
Dim FileToCopy As String
Dim NewCopy As String
FileToCopy = My.Resources.THEFILEIWANT <- only this part doesn't work
NewCopy = "Files\THEFILEIWANT.exe"
If System.IO.File.Exists(FileToCopy) = True Then
System.IO.File.Copy(FileToCopy, NewCopy)
End If
End Sub
This is needed so when ther file doesn't exists the file gets created/copied.
Does anyone knows how I can call the file from the resource folder?
Tried this ` Dim writePermission As FileIOPermission
writePermission = New FileIOPermission(FileIOPermissionAccess.Write)
If (SecurityManager.IsGranted(writePermission)) Then
My.Computer.FileSystem.WriteAllBytes("Files", My.Resources.unscrambler, False)
End If`
But I'm getting a invalid permission error.
I am still a beginner but I could suggest using a packer, such as the one included with CodePlex's Confuser. It packs multiple assemblies into one (as do all packers), and obviously, Confuser offers obfuscation, and is Free.
*One warning!* Packers have been known to raise alerts in Anti-virus software, so check your app with different AV software.
Hope this info is useful. :)
