Try placing this in the control source property of a textbox on your report (include the = sign):

= Environ("username")

Hi mbizup,  I did try that in a text box like this: ="Printed: " & Now() & " by " & Environ("username")

I get a message "Enter parameter value" and 'Environ', will this function only work by itself?

An alternate (and better) solution is to use an API function to get the user name.  

Set your textbox control source to this:

= GetUserName()

and add this code to a module:

Option Explicit
     ' Declare for call to mpr.dll.
   Declare Function WNetGetUser Lib "mpr.dll" _
      Alias "WNetGetUserA" (ByVal lpName As String, _
      ByVal lpUserName As String, lpnLength As Long) As Long

   Const NoError = 0       'The Function call was successful


   Function GetUserName()

      ' Buffer size for the return string.
      Const lpnLength As Integer = 255

      ' Get return buffer space.
      Dim status As Integer

      ' For getting user information.
      Dim lpName, lpUserName As String

      ' Assign the buffer size constant to lpUserName.
      lpUserName = Space$(lpnLength + 1)

      ' Get the log-on name of the person using product.
      status = WNetGetUser(lpName, lpUserName, lpnLength)

      ' See whether error occurred.
      If status = NoError Then
         ' This line removes the null character. Strings in C are null-
         ' terminated. Strings in Visual Basic are not null-terminated.
         ' The null character must be removed from the C strings to be used
         ' cleanly in Visual Basic.
         GetUserName = Left$(lpUserName, InStr(lpUserName, Chr(0)) - 1)
      Else

         ' An error occurred.
         GetUserName = ""
      End If



   End Function

Open in new window


The function is a modified version of the code here:

Its simply modified to return a string rather than posting a message box

<< I get a message "Enter parameter value" and 'Environ', will this function only work by itself?>>

Are you certain that you included the = sign in the control source?  It looks like it should have worked.

Edit:

although, depending on your security settings, Environ might not work.   Try the API suggestion I just posted...
