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

Please refer to VBScript to loop through all files in a folder for one part and to How to create text file and write to it in vbscript for other part. Please search this site and use Google before posting questions about simple issues.
