ShellExecute does not send $CrLf 's

[Gösta H. Lovgren-2]

I can't seem to send a text string with $CrLf's embedded. In Body$ below, Eudora shows Test Test instead of two separate lines. Do I need to send something else other than $CrLf 's?

'
Sub W_Email_Tape        
 common_Locals
  Local ppr As  String Pointer                 
  Local subj, body As String

  'find name only
  i = InStr(-1, Prm.Current_File_Name, "\") + 1
   subj$ = Mid$(Prm.Current_File_Name, i)  
     subj$ = Trim$(subj$)
'     
   Body$ = "test " & $CrLf & $CrLf & "test" '  Tape_to_String
   
  s$ = "[EMAIL="gosta"]MailTo:gosta[/EMAIL]" & _
       "?Subject=" & subj$ & _
        "&Body=" & Body$ & _
       Chr$(0)
  ppr = StrPtr(s$)
'>>>>>> Does not send $crlf's in Body$ or Eudora does not receive them.

Nix request. Found the answer here: http://www.ianr.unl.edu/internet/mailto.html

just had to

     Replace $CrLf With "%0a" In Body$

There appears to be a limit of about 2,000 characters that can be sent with shellExecute

  i = InStr(-1, Prm.Current_File_Name, "\") + 1
   subj$ = Mid$(Prm.Current_File_Name, i)  
     subj$ = Trim$(subj$)
'              
   Body$ = Tape_to_String 
   Replace $CrLf With "%0a " In Body$                             
em20:   
  ln = Len(Body$)
   If ln > 2000 Then
     ?"The detailed Tape is too long to send from here." & $CrLf  & $CrLf & _
      "  Try just sending the totals and summary,"& $CrLf & _
      "and Attaching the file saved as '.Txt' from ." &  _
      "your email client." _
      ,%top, $Title
     Exit Sub 
   End If
 
 '2529 in orig too long?
'  n = 2000             
'   Body$ = Left$(body$, n) 
'   Subj$ = Using$("   used #, of #, ", Len(Body$), ln)
  s$ = "MailTo:" & _
       "?Subject=" & subj$ & _
        "&Body=" & Body$ & _
       Chr$(0)
  ppr = StrPtr(s$)
  ShellExecute 0, "open", ByVal ppr, ByVal 0&, ByVal 0&, %SW_SHOWNORMAL 
 
End Sub
'

Or am I doing something wrong here? When Body$ is something over 2,000 chars, it just doesn't execute. I tried any number of things, thinking it may have been a particular char sequence but that doesn't seem to be it. Anybody got any ideas? (Well I know some do but I mean about a char limit on ShellExecute.)

No it didn't Mike. Unless I tried it wrong (a quite real possibility).

Passing CHR$("MIKE",0,0,"DOTY") only receives 4 characters.
Change to CHR$("MIKE",1,1"DOTY") and it receives all 10 characters.

I've passed over 32,000 characters using this:

I don't doubt it Mike. If I'm not using Wait_Shell wrong (see above snippet), the 2,000 bytes may be an inherent limitation in the "Mailtto:" function.

I tried WaitShell with a small msg but it failed as well so either I'm using it wrong or WS won't execute the MailTo cmd.

Thanks your trying.

Try it with ShellExecuteEx and a separate parameter string (SEI.LpParameters) as shown here:

I get an Invalid handle error. I suspect because I used hdlg (a global). The function succeeds though, in that it launches the MailtTo but some of the Body of the message is truncated. which doesn't happen with ShellExecute:

But won't send a long one.

The same Tape to send was used in each case.
