Excel VBA ENVIRON(Environment)

The VBA ENVIRON function (stands for ENVIRONMENT) which can be categorized as an Information Function as this function returns the values for an operating system environment variables. Environment (Operating System) variables contain information about profiles of all users, user name, user profile, a home folder for the user, etc. This function returns a string value.

Syntax 

Syntax of VBA Environ

This function has only one argument that is ‘Expression.’ We can specify the numeric position (integer value) representing the numeric position of the environment variable in the environment variable table or variable name itself.

If we specify the numeric position, then the function returns the environment variable and its value, both with an equal sign in between.

Example #1

Open Command Prompt using ENVIRON Function in VBA.

To do the same, steps would be:

Insert the command button using the ‘Insert’ command available in the ‘Controls’ group in the ‘Developer’ tab or use the shortcut excel key (Alt+F11).

VBA Environ Example 1

If the ‘Developer’ tab is not visible, use the following steps to make the tab visible.

Click on ‘File’ and choose ‘Options’ from the list.

VBA Environ Example 1-1

Choose ‘Customize Ribbon’ from the left menu and check the box for the ‘Developer’ tab and click on ‘OK.’

VBA Environ Example 1-2

Now the ‘Developer tab’ is visible.

While inserting the command button, if we keep pressing the ALT key, then the edges of the command button will be along with the border of the cell. Change the properties of the inserted command button using the contextual menu, which we get by right-clicking on the ‘Command button.’

We have formed the entire structure. Now we need to write the code.

Activate the ‘Design Mode,’ and right-click on the “Fetch all files details” button to choose the “View Code” from the contextual menu to add the code for the switch.

We will declare some variables first in the module.

variable Example 2-15

Below is the code added to a “Fetch all files details” button.

Code:

Private Sub FetchFilesBtnCommandButton_Click()
iRow = 14
fPath = Environ("HOMEPATH") & "" & SelectTheFolderComboBox.Value
If fPath <> "" Then

Set FSO = New Scripting.FileSystemObject
If FSO.FolderExists(fPath) <> False Then
Set SourceFolder = FSO.GetFolder(fPath)

If Sheet2.IncludingSubFoldersCheckBox.Value = True Then
IsSubFolder = True
Else
IsSubFolder = False
If SourceFolder.Files.Count = 0 Then
MsgBox "No files exists in this Folder" & vbNewLine & vbNewLine & "Check your folder path and Try Again !!", vbInformation
Exit Sub
End If
End If

Call ClearResult

If FetchAllTypesOfFilesCheckBox.Value = True Then

Call ListFilesInFolder(SourceFolder, IsSubFolder)
Call ResultSorting(xlAscending, "C14", "D14", "E14")
Else

Call ListFilesInFolderXtn(SourceFolder, IsSubFolder)
Call ResultSorting(xlAscending, "C14", "D14", "E14")
End If

FilesCountLabel.Caption = iRow - 14

Else
MsgBox "Selected Path Does Not Exist !!" & vbNewLine & vbNewLine & "Select Correct One and Try Again !!", vbInformation
End If
Else
MsgBox "Folder Path Can not be Empty !!" & vbNewLine & vbNewLine & "", vbInformation
End If

End Sub

Define the ‘ClearResult’ function in the module. To insert the module, select ‘ThisWorkbook’ then ‘Insert’ and then ‘Module”’.

Module Example 2-16

Write the following code in the module.

Code for ClearResult

Clearresult Example 2-17

There are more subroutines like ‘ListFilesInFolder,’ ‘ListFilesInFolderXtn,’ ‘ResultSorting,’ we will define all these subroutines in the module.

‘ListFilesInFolder’

Code:

Public Sub ListFilesInFolder(SourceFolder As Scripting.Folder, IncludeSubfolders As Boolean)

If IncludeSubfolders Then
For Each SubFolder In SourceFolder.SubFolders
ListFilesInFolderXtn SubFolder, True
Next SubFolder
End If

Set FileItem = Nothing
Set SourceFolder = Nothing
Set FSO = Nothing

End Sub

‘ResultSorting’

Sub ResultSorting(xlSortOrder As String, sKey1 As String, sKey2 As String, sKey3 As String)
Range("C13").Select
Range(Selection, Selection.End(xlDown)).Select
Range(Selection, Selection.End(xlToRight)).Select

Selection.Sort Key1:=Range(sKey1), Order1:=xlSortOrder, Key2:=Range(sKey2 _
), Order2:=xlAscending, Key3:=Range(sKey3), Order3:=xlSortOrder, Header _
:=xlGuess, OrderCustom:=1, MatchCase:=False, Orientation:=xlTopToBottom _
, DataOption1:=xlSortNormal, DataOption2:=xlSortNormal, DataOption3:= _
xlSortNormal

Range("B14").Select
End Sub

In ‘ListFilesInFolderXtn’ subroutine, we have called a function named ‘ReturnFileType’ and ‘GetFileTypeArray’, we need to define the functions in the same module.

‘ReturnFileType’

Code:

Public Function ReturnFileType(fileType As String, FileArray As Variant) As Boolean

Dim i As Integer

IsFileTypeExists = False

For i = 1 To UBound(FileArray) + 1

If FileArray(i - 1) = fileType Then

IsFileTypeExists = True
Exit For

Else
IsFileTypeExists = False
End If

Next

End Function

‘GetFileTypeArray’

Code:

Public Function Get_File_Type_Array() As Variant

Dim i, j, TotalSelected As Integer
Dim arrList() As String
TotalSelected = 0
For i = 0 To Sheet2.FileTypesListBox.ListCount - 1
If Sheet2.FileTypesListBox.Selected(i) = True Then
TotalSelected = TotalSelected + 1
End If
Next

ReDim arrList(0 To TotalSelected - 1) As String
j = 0
i = 0
For i = 0 To Sheet2.FileTypesListBox.ListCount - 1

If Sheet2.FileTypesListBox.Selected(i) = True Then
arrList(j) = Left(Sheet2.FileTypesListBox.List(i), InStr(1, Sheet2.FileTypesListBox.List(i), "(") - 1)
j = j + 1
End If

Next

Get_File_Type_Array = arrList

End Function

We have a command button captioned as ‘Export to Excel File,’ we need to write the code for this button as follows:

Export to excel File
Export to excel File Example 2-19

In Module, define the subroutine named ‘Export_to_excel.’

Code:

Sub Export_to_excel()
On Error GoTo err


Dim xlApp As New Excel.Application
Dim xlWB As New Workbook

Set xlWB = xlApp.Workbooks.Add
'xlWB.Add
xlApp.Visible = False

ThisWorkbook.Activate
Range("B13").Select
Range(Selection, Selection.End(xlDown)).Select
Range(Selection, Selection.End(xlToRight)).Select

Selection.Copy

xlApp.Visible = True
xlWB.Activate
xlWB.Sheets("Sheet1").Select
xlWB.Sheets("Sheet1").Range("B2").PasteSpecial Paste:=xlPasteValues
xlWB.Sheets("Sheet1").Cells.Select
xlWB.Sheets("Sheet1").Cells.EntireColumn.AutoFit
xlWB.Sheets("Sheet1").Range("B2").Select
Exit Sub
err:
MsgBox ("Error Occured while exporting. Try again")

End Sub

We have one more command button captioned as ‘Export to Text File.’ We will write the code for the command button as follows:

VBA Environ Example 2-20
Export to Text File Example 2-21

In this code, we can see that we have a user form, which we need to design using the following steps:

Right Click on the ‘Sheet2 (Example2)’ sheet and choose ‘Insert’ and then ‘UserForm’ from the menu.

UserForm Example 2-22

Design the UserForm using tools from the toolbox.

Design the UserForm Example 2-23

We have used ‘Labels,’ ‘Combo Box,’ ‘Text Box,’ and ‘Command buttons’ for the Userform and have changed caption and name for all the components.

For the first command button (OK), we have to write the code as follows:

Code:

Private Sub CommandButton1_Click()
Dim iSeperator As String

If ComboBox1.Value = "Other" Then
iSeperator = TextBox1.Value
Else
iSeperator = ComboBox1.Value
End If

If iSeperator = "" Then
If MsgBox("Hello You have not selected any delimeter." & vbNewLine & vbNewLine & _
" It will be very difficult to read the Text file, without specific delimiter", vbYesNo) = vbYes Then

Call textfile(iSeperator)
Else

Exit Sub

End If

Else

Select Case ComboBox1.ListIndex

Case 0: iSeperator = ","
Case 1: iSeperator = "|"
Case 2: iSeperator = "vbTab"
Case 3: iSeperator = ";"

End Select
Call textfile(iSeperator)
Unload Me
End If
End Sub

We have called the ‘textfile’ function in the subroutine for the command button, so we need to define the ‘textfile’ function in the module.

Code:

Sub textfile(iSeperator As String)
Dim iRow, iCol
Dim iLine, f
ThisWorkbook.Activate
Range("B13").Select
TotalRowNumber = Range(Selection, Selection.End(xlDown)).Count - 12
If iSeperator <> "vbTab" Then
Open ThisWorkbook.Path & "File1.txt" For Output As #1
Print #1, ""
Close #1
Open ThisWorkbook.Path & "File1.txt" For Append As #1
For iRow = 13 To TotalRowNumber
iLine = ""
For iCol = 2 To 7
iLine = iLine & iSeperator & Cells(iRow, iCol).Value
Next
Print #1, iLine
Next
Close #1
Else
Open ThisWorkbook.Path & "File1.txt" For Output As #1
Print #1, ""
Close #1
Open ThisWorkbook.Path & "File1.txt" For Append As #1
For iRow = 13 To TotalRowNumber
iLine = ""
For iCol = 2 To 7
iLine = iLine & vbTab & Cells(iRow, iCol).Value
Next
Print #1, iLine
Next
Close #1
End If
f = Shell("C:WINDOWSnotepad.exe " & ThisWorkbook.Path & "File1.txt", vbMaximizedFocus)
MsgBox "Your File is saved in " & ThisWorkbook.Path & "File1.txt"
End Sub

For command button 2 (Cancel), we need to write the following code. Double click on the cancel button to write the code.

command button 2 Example 2-24

For the Combo Box for selecting a specifier, write the following code.

Combo Box Example 2-25

For the UserForm, write the following code.

UserForm Example 2-26

For the ‘Fetch all type of files’ checkbox, write the following code.

Fetch all type of files Example 2-27
Fetch Example 2-28

For the ‘ListBox’ for file types, write the following code.

listbox Example 2-29
Filetypelist box Example 2-30

For the ‘SelectTheOrder’ combo box, write the following code.

VBA Environ Example 2-31

Code:

Private Sub SelectTheOrderComboBox_Change()
Select Case (SelectTheOrderComboBox.Value)
Case "Ascending"
If SortByComboBox.Value = "File Name" Then
Call ResultSorting(xlAscending, "C14", "E14", "G14")
End If
If SortByComboBox.Value = "File Type" Then
Call ResultSorting(xlAscending, "F14", "E14", "C14")
End If
If SortByComboBox.Value = "File Size" Then
Call ResultSorting(xlAscending, "E14", "C14", "G14")
End If
If SortByComboBox.Value = "Last Modified" Then
Call ResultSorting(xlAscending, "G14", "C14", "E14")
End If
Case "Descending"
If SortByComboBox.Value = "File Name" Then
Call ResultSorting(xlDescending, "C14", "E14", "G14")
End If
If SortByComboBox.Value = "File Type" Then
Call ResultSorting(xlDescending, "F14", "E14", "C14")
End If
If SortByComboBox.Value = "File Size" Then
Call ResultSorting(xlDescending, "E14", "C14", "G14")
End If
If SortByComboBox.Value = "Last Modified" Then
Call ResultSorting(xlDescending, "G14", "C14", "E14")
End If
Case Default
Exit Sub
End Select
End Sub

For the ‘Sort by’ combo box, we will write the following code.

VBA Environ Example 2-32

Code:

Private Sub SortByComboBox_Change()
Select Case (SelectTheOrderComboBox.Value)
Case "Ascending"
If SortByComboBox.Value = "File Name" Then
Call ResultSorting(xlAscending, "C14", "E14", "G14")
End If
If SortByComboBox.Value = "File Type" Then
Call ResultSorting(xlAscending, "F14", "E14", "C14")
End If
If SortByComboBox.Value = "File Size" Then
Call ResultSorting(xlAscending, "E14", "C14", "G14")
End If
If SortByComboBox.Value = "Last Modified" Then
Call ResultSorting(xlAscending, "G14", "C14", "E14")
End If
Case "Descending"
If SortByComboBox.Value = "File Name" Then
Call ResultSorting(xlDescending, "C14", "E14", "G14")
End If
If SortByComboBox.Value = "File Type" Then
Call ResultSorting(xlDescending, "F14", "E14", "C14")
End If
If SortByComboBox.Value = "File Size" Then
Call ResultSorting(xlDescending, "E14", "C14", "G14")
End If
If SortByComboBox.Value = "Last Modified" Then
Call ResultSorting(xlDescending, "G14", "C14", "E14")
End If
Case Default
Exit Sub
End Select
End Sub

Now we have written the entire code. Now we can select the desired folder and file type and find out the list for files, which we can sort by ‘File Name,’ ‘File Type,’ ‘File Size,’ or ‘Last-Modified’ and can export the list to excel or text file.

VBA Environ Example 2-33

Things to Remember

If the value we specify for the ‘investing’ argument is not in the environment string table, the ENVIRON function returns the zero-length string.
