Function UnZip(PathToUnzipFileTo As Variant, FileNameToUnzip As Variant)

    ' Unzips a file

  ' the "24" argument below will supress any dialogs if the file already exist. The file will

    ' be replaced. See http://msdn.microsoft.com/en-us/library/windows/desktop/bb787866(v=vs.85).aspx

    objOApp.Namespace(varFileNameFolder).CopyHere objOApp.Namespace(FileNameToUnzip).items, 24

End Function

Note the 24 in the last line. This suppresses any dialog boxes in the event of the extracted file(s) already existing. See http://msdn.microsoft.com/en-us/library/windows/desktop/bb787866(v=vs.85).aspx for more details.

Improvements to this could could consist of checking to see if the extracted files exist and handling that by renaming, deleting, etc.

On this page you can find example code to copy, move and delete files and folders.

There are three sections on this page :

1) Copy and Move files and folders

2) Delete files and folders

3) Special Folders

4) VBS script to clear the Temp folder

Copy and Move files and folders

Below are a few examples to copy and move files and folders.

For one file you can use the VBA Name and FileCopy function

and for entire folders or a lot of files use the other macro example’s

Sub Copy_One_File()

    FileCopy "C:\Users\Ron\SourceFolder\Test.xls", "C:\Users\Ron\DestFolder\Test.xls"

End Sub

Sub Move_Rename_One_File()

'You can change the path and file name

    Name "C:\Users\Ron\SourceFolder\Test.xls" As "C:\Users\Ron\DestFolder\TestNew.xls"

End Sub

Delete files and folders

Important !

Read this page from Chip Pearson first

http://www.cpearson.com/excel/Recycle.htm

From Chip’s site :

You need to remember, though, that Kill permanently deletes the file.

There is no way to “undo” the delete. The file is not sent to the Windows Recycle Bin

( Same for the macro’s that use the filesystemobject )

Sub DeleteExample1()

'You can use this to delete all the files in the folder Test

    On Error Resume Next

    Kill "C:\Users\Ron\Test\*.*"

    On Error GoTo 0

End Sub

Sub DeleteExample2()

'You can use this to delete all xl? files in the folder Test

    On Error Resume Next

    Kill "C:\Users\Ron\Test\*.xl*"

    On Error GoTo 0

End Sub

Sub DeleteExample3()

'You can use this to delete one xls file in the folder Test

    On Error Resume Next

    Kill "C:\Users\Ron\Test\ron.xls"

    On Error GoTo 0

End Sub

Sub DeleteExample4()

'You can use this to delete the whole folder

'Note: RmDir delete only a empty folder

    On Error Resume Next

    Kill "C:\Users\Ron\Test\*.*"    ' delete all files in the folder

    RmDir "C:\Users\Ron\Test\" ' delete folder 

    On Error GoTo 0

End Sub

Sub Delete_Whole_Folder()

'Delete whole folder without removing the files first like in DeleteExample4

    Dim FSO As Object

    Dim MyPath As String

    Set FSO = CreateObject("scripting.filesystemobject")

    MyPath = "C:\Users\Ron\Test"  '<< Change

    If Right(MyPath, 1) = "\" Then 

        MyPath = Left(MyPath, Len(MyPath) - 1)

    End If

    If FSO.FolderExists(MyPath) = False Then

        MsgBox MyPath & " doesn't exist"

        Exit Sub

    End If

    FSO.deletefolder MyPath

End Sub

Sub Clear_All_Files_And_SubFolders_In_Folder()

'Delete all files and subfolders

'Be sure that no file is open in the folder

    Dim FSO As Object

    Dim MyPath As String

    Set FSO = CreateObject("scripting.filesystemobject")

    MyPath = "C:\Users\Ron\Test"  '<< Change

    If Right(MyPath, 1) = "\" Then 

        MyPath = Left(MyPath, Len(MyPath) - 1)

    End If

    If FSO.FolderExists(MyPath) = False Then

        MsgBox MyPath & " doesn't exist"

        Exit Sub

    End If

    On Error Resume Next

    'Delete files

    FSO.deletefile MyPath & "\*.*", True

    'Delete subfolders

    FSO.deletefolder MyPath & "\*.*", True

    On Error GoTo 0

End Sub

SpecialFolders

How do I get the path of a special folder and open the folder ?

Sub GetSpecialFolder()

'Special folders are : AllUsersDesktop, AllUsersStartMenu

'AllUsersPrograms, AllUsersStartup, Desktop, Favorites

'Fonts, MyDocuments, NetHood, PrintHood, Programs, Recent

'SendTo, StartMenu, Startup, Templates

'Get Favorites folder and open it

    Dim WshShell As Object

    Dim SpecialPath As String

    Set WshShell = CreateObject("WScript.Shell")

    SpecialPath = WshShell.SpecialFolders("Favorites")

    MsgBox SpecialPath

    'Open folder in Explorer

    Shell "explorer.exe " & SpecialPath, vbNormalFocus

End Sub

Sub VBA_GetSpecialFolder_functions()

'Here are a few VBA path functions

    MsgBox Application.Path

    MsgBox Application.DefaultFilePath

    MsgBox Application.TemplatesPath

    MsgBox Application.StartupPath

    MsgBox Application.UserLibraryPath

    MsgBox Application.LibraryPath

End Sub

Temp folder

Without code you can do this to open the temp folder

Start>Run

Enter %temp%

OK

Or use one of the two code examples

Sub GetTempFolder_1()

    MsgBox Environ("Temp")

    'Open folder in Explorer

    Shell "explorer.exe " & Environ("Temp"), vbNormalFocus

End Sub

Sub GetTempFolder_2()

    Dim FSO As Object, TmpFolder As Object

    Set FSO = CreateObject("scripting.filesystemobject")

    Set TmpFolder = FSO.GetSpecialFolder(2)

    MsgBox TmpFolder

    'Open folder in Explorer

    Shell "explorer.exe " & TmpFolder, vbNormalFocus

End Sub

0 = The Windows folder contains files installed by the Windows operating sys

1 = The System folder contains libraries, fonts, and device drivers

Excel VBA: Function to get logged in user name (plus the Environ Function)

One commonly asked task is how can you get the name of the current user of an Excel spreadsheet into a cell in the spreadsheet. A lot of people quickly stumble across the UserName property in VBA and create a function similar to this:

Function UserNameOffice() As String

     UserNameOffice = Application.UserName

End Function

But as you know, that only returns the name of the user according to the registration information of Office. A lot of companies set that at something generic like “User”or “Registered Owner”. That’s not what you really want though right? You really want the user’s name based on their Windows login. How do you get that ?…. well it’s a little complicated with an API call from VBA as shown here is below:

Private Declare Function GetUserName Lib "advapi32.dll" Alias "GetUserNameA"(ByVal lpBuffer As String, nSize As Long) As Long

Function UserNameWindows() As String

    Dim lngLen As Long

    Dim strBuffer As String

    Const dhcMaxUserName = 255

    strBuffer = Space(dhcMaxUserName)

    lngLen = dhcMaxUserName

    If CBool(GetUserName(strBuffer, lngLen)) Then

        UserNameWindows = Left$(strBuffer, lngLen - 1)

    Else

        UserNameWindows = ""

    End If

End Function

Then all you have to do in the cell of choice is enter the formula:

=UserNameWindows()

But as *Mike* reminded me in a comment on my original post (this is the updated version)….

There is the Environ Function in VBA that makes this a walk in the park without the API hassles:

Function UserNameWindows() As String

    UserName = Environ("USERNAME")

End Function

Thanks *Mike* for bringing that up….

I remember using Environ to get the current location of  the “My Documents“ folder for the current user:

MsgBox Environ("USERPROFILE") + "\My Documents"

So having my memory jarred on the Environ function, I thought I would check VBA help to see what else this Little gem provided. And boy, how disappointing Help was… here is what it looks like: Environ Help. Not too useful I thought… So I decided to figure it out on my own and loop thru all the arguments possible with Environ. Copy and run this little routine to see all that Environ offers:

MsgBox Environ("USERPROFILE") + "\My Documents"Public Sub EnvironFunction()

    Dim nCount As Integer

    nCount = nCount + 1

    Do Until Environ(nCount) = ""

        Debug.Print Environ(nCount)

        nCount = nCount + 1

    Loop

End Sub

There are lots of useful things in there including APPDATA, COMPUTERNAME, HOMEDRIVE, HOMEPATH, OS, USERDOMAIN and more… Hopefully you will find it useful and I won’t forget about it again.

****Nice to see blogging helps you remember what you forgot and that readers often help writers more than the other way around

Here’s a complete list (that I know of) of the named arguments for the Environ Function:

gAttach!  allows you to easily attach files to new messages in Gmail or Google Apps Mail.

All the features available in Windows that were once only available to your desktop mail-using friends are now available to all Gmail users.

Website: http://www.gattach.net/index.html

For example, if you had a column of data that contained a phone number without separators (1234567890), you could easily change the contents to be formatted to include separators (123-456-7890).

Magic/Replace will also change the case of the data in a field.

You would use Excel or some other more powerful tool for major data cleanup. However, Magic/Replace works well and is quick for simple data cleanup. Magic/Replace is brought to you by Dabble DB – an easy way to create online databases.

Like a big catfish going after a dough ball, folks are snapping up malware like it’s a $20 bill blowing across a parking lot. Specifically, we’re talking about the old “Antivirus XP”, which is now making the rounds re-branded as “Antivirus Plus”.

Behold…

System Tray

Desktop Icon

Fake Infection Alert

And I’d be willing to bet there are entries in the Quick Launch bar and start menu as well.

ATTENTION PLANET EARTH!

** Antivirus XP 2008, 2009 and Antivirus Plus are SPYWARE! **

They are not helpful programs, and you certainly shouldn’t give these folks your credit card number, OK??

Scroll down for removal instructions. Thank you!

Props to Kevin Royalty [SBS-MVP] for snapping these pics on his camera phone.

REMOVAL
According to Kevin, our old pal Malwarebytes still gets rid of this nasty. Thanks for the heads-up Kev!
