Hi All,


I am really struggling with trying to use Process.Start("Regedit.exe", "/e path + argument) to work.

I do not have a set path as the user is to be able to select a path to export a registry key to. The problem is that if I choose a folder that does not contain a space in the name, it works fine. If I select a folder or create one with a space in it, it does not work.

For testing, I created 2 folders on a USB stick;

Test
Test 1

The code below works when selecting "Test" but not when selecting "Test 1"


The only way I have it working is that I have it save to the root of c:\ and then copy it from C:\ over to "chosenpath" but I know that this is a stupid way to do it. There must be something small I am missing.

Can anyone please please please help me with a solution? I have tried everything I know and can find.

What I have tried:

With FolderBrowserDialog1
.Description = "Select destination folder to save the backup. Create a new folder if you wish."
.ShowNewFolderButton = True
' Opens the folder dialog to select the source folder
If .ShowDialog = Windows.Forms.DialogResult.OK Then
chosenpath = .SelectedPath
finalpath = chosenpath & "\RegBackup.txt HKEY_LOCAL_MACHINE\SOFTWARE\TestRegKey"

End If
End With
' Checks to see if a destination folder was selected or "Cancel" was clicked
If chosenpath IsNot Nothing Then
MsgBox("Reg will be exported to " & finalpath, MsgBoxStyle.OkOnly)
System.Diagnostics.Process.Start("Regedit.exe", "/e " & finalpath)

ElseIf chosenpath Is Nothing Then
MsgBox("Backup aborted. No destination folder selected.", MsgBoxStyle.Exclamation, Title:="Backup aborted!")
Exit Sub
Else
End If




I have tried the following;

Adding quotation marks around the chosenpath (As recommended by a post I found however it was a very old post)
finalpath = """" & chosenpath & """" & "\RegBackup.txt HKEY_LOCAL_MACHINE\SOFTWARE\TestRegKey"

This did not work

I have also tried another recommended solution I found;

string finalpath = string.format(@"\{0}\", chosenpath & "\RegBackup.txt HKEY_LOCAL_MACHINE\SOFTWARE\TestRegKey")

That does not work,

Next I tried;

finalpath = "@" & chosenpath & "\RegBackup.txt HKEY_LOCAL_MACHINE\SOFTWARE\TestRegKey")

That does not work.

You want the double quotes around the whole path, not a portion of it, so that the whole text is treated as a single parameter:
VB
System.Diagnostics.Process.Start("Regedit.exe", "/e ""D:\Test 1\My file.txt""")

That did not really answer my question however after messing around with the code and I tried the double quotes (as you suggested) instead of 4, I was able to get this to work.

Thanks for the advice though.
This is how I finally got it to work..

System.Diagnostics.Process.Start("Regedit.exe", "/e """ & chosenpath & "\RegBackup.txt""" + " HKEY_LOCAL_MACHINE\SOFTWARE\TestRegKey")
