Automated file upload using IE, without user interaction - VBA

Areas>Languages>VBA to v. 6
Areas>VBA>POST http method
Areas>ASP / ASP.Net>File & data transfer

To upload specific file using VBS/ASP with client-side compression see Zlib class of ScriptUtilities library and its upload sample.

There are many samples which lets you accept uploaded files from multipart/form-data forms with <input type=file> in ASP on this site (See home page of Pure ASP file upload with progress).
But what to do if you want to upload some specific file without user interaction? For example, you have a next form:

 <Form Action=http://127.0.0.30/util/up/free/upload.asp
  Method=Post ENCTYPE="multipart/form-data">
  <Input Type=File Name=FileField>
  <Input Type=Submit>
 </Form>

Next VBA code simulates the same submit of the form (upload of file) using IE and VBA. You can use the code in VisualBasic 5 and 6 or in Excel, Word and Access.

You can use ScriptUtils.ASPForm to accept uploaded files in ASP. ScriptUtils.ASPForm contains hi-performance, low resources consumption algorithm which can accept up to 2GB of data.

UploadFile "http://127.0.0.30/util/up/free/upload.asp", _
  "F:\work\Pstruh\Articles\upload\xx", "FileField"

'******************* upload - begin
'Upload file using input type=file
Sub UploadFile(DestURL As String, FileName As String, _
  Optional ByVal FieldName As String = "File")
  Dim sFormData As String, d As String
  
  'Boundary of fields.
  'Be sure this string is Not In the source file
  Const Boundary As String = "---------------------------0123456789012"

  'Get source file As a string.
  sFormData = GetFile(FileName)
  
  'Build source form with file contents
  d = "--" + Boundary + vbCrLf
  d = d + "Content-Disposition: form-data; name=""" + FieldName + """;"
  d = d + " filename=""" + FileName + """" + vbCrLf
  d = d + "Content-Type: application/upload" + vbCrLf + vbCrLf
  d = d + sFormData
  d = d + vbCrLf + "--" + Boundary + "--" + vbCrLf
  
  'Post the data To the destination URL
  IEPostStringRequest DestURL, d, Boundary
End Sub

'sends URL encoded form data To the URL using IE
Sub IEPostStringRequest(URL As String, FormData As String, Boundary As String)
  'Create InternetExplorer
  Dim WebBrowser: Set WebBrowser = CreateObject("InternetExplorer.Application")
  
  'You can uncoment Next line To see form results
  'WebBrowser.Visible = True
   
  'Send the form data To URL As POST request
  Dim bFormData() As Byte
  ReDim bFormData(Len(FormData) - 1)
  bFormData = StrConv(FormData, vbFromUnicode)

  WebBrowser.Navigate URL, , , bFormData, _
    "Content-Type: multipart/form-data; boundary=" + Boundary + vbCrLf

  Do While WebBrowser.busy
'    Sleep 100
    DoEvents
  Loop
  WebBrowser.Quit
End Sub

'read binary file As a string value
Function GetFile(FileName As String) As String
  Dim FileContents() As Byte, FileNumber As Integer
  ReDim FileContents(FileLen(FileName) - 1)
  FileNumber = FreeFile
  Open FileName For Binary As FileNumber
    Get FileNumber, , FileContents
  Close FileNumber
  GetFile = StrConv(FileContents, vbUnicode)
End Function
