Generating the hash value of a file

Question

I have managed to gather code and tried to generate the hash value of a file, but in the present code I need to drag the file on the VBScript, then it gives the hash value.<

Here we go:

Set fso = CreateObject("Scripting.FileSystemObject")
Dim oMD5:  Set oMD5 = CreateObject("System.Security.Cryptography.MD5CryptoServiceProvider")
Dim oLog 'As Scripting.TextStream

Set oArgs = WScript.Arguments

If oArgs.Count = 1 Then
    sFolderPath = GetFolderPath()
    Set oLog = fso.CreateTextFile(sFolderPath & "\FileHash.csv", True)
    oLog.Write "sep=" & vbTab & vbCrLf
    CheckFolder oArgs(I)
    oLog.Close
    Msgbox "Done!"
Else
    Msgbox "Drop Folder"
End If

Sub CheckFolder(sFolderPath)
    Dim sKey
    Dim oFolder 'As Scripting.Folder
    Set oFolder = fso.GetFolder(sFolderPath)

    For Each oFile In oFolder.Files
        oLog.Write oFile.Path & vbTab & GetMd5(oFile.Path) & vbCrLf
    Next

    For Each oChildFolder In oFolder.SubFolders
        CheckFolder oChildFolder.Path
    Next
End Sub

Function GetFolderPath()
    Dim oFile 'As Scripting.File
    Set oFile = fso.GetFile(WScript.ScriptFullName)
    GetFolderPath = oFile.ParentFolder
End Function

Function GetMd5(filename)
    Dim oXml, oElement

    oMD5.ComputeHash_2(GetBinaryFile(filename))

    Set oXml = CreateObject("MSXML2.DOMDocument")
    Set oElement = oXml.CreateElement("tmp")
    oElement.DataType = "bin.hex"
    oElement.NodeTypedValue = oMD5.Hash
    GetMd5 = oElement.Text
End Function

Function GetBinaryFile(filename)
    Dim oStream: Set oStream = CreateObject("ADODB.Stream")
    oStream.Type = 1 'adTypeBinary
    oStream.Open
    oStream.LoadFromFile filename
    GetBinaryFile= oStream.Read
    oStream.Close
    Set oStream = Nothing
End Function
