Try to use a dynamic string instead of az * 50000
Then use StrPtr() instead of VarPtr()..

That's the way it was at first Edwin. Notice the code that is commented out.
But it also had the same problem. I tried with the ASCIIZ string because 'ShellExecute'
requires an ASCIIZ string as argument, as I noticed in the function declare in
win32api.inc .

In your REPLACE, don't you need REPLACE ANY?

The way it's written, only the first occurrence of the charcters will be replaced. Maybe something barfs if you leave the control characters in there. Longer message, greater chance for occrrence of control characters?

Michael,
Not really. The REPLACE statement replaces all occurrences of MatchString in MainString with
NewString.
Furthermore, in this demo, the messagetext consists of nothing but characters "a"
without any control characters and the program still crashes..
Thanks for your input though.

Code:

[b]LOCAL mText AS ASCIIZ * 50000[/b]
change to this...?
 mText = "mailto:" & "[email protected]" & "?" & _
         "Subject=" & "Some subject" & _
         "&Body="   & mStr 
Perhaps it will work..?

Fred,
I hope I understood you correctly. I replaced this:

Code:

   mText = "mailto:" & "[email protected]" & "?"
   mText = mText & "Subject=" & "Some subject"
   mText = mText & "&Body="   & mStr

with this:

Code:

    mText = "mailto:" & "[email protected]" & "?" & _
            "Subject=" & "Some subject" & _
            "&Body="   & mStr

while mText is still:
LOCAL mText AS ASCIIZ * 50000
I'm sorry,but no change in behavior...
Thanks
Eddy

Individual "lines" of message body text in an email (ie, between CR or CR/LF) should be
less than 1000 characters (see the appropriate RFC for more info).

Can imagine the limitation is within the ShellExecute call. It was designed
for calling upp "associated" app's, etc, so guess the buffers for the parameters
has their limits - this causing the GPF on too long strings. Don't think
ShellExecuteEx can do it any better either.

Solution? Use own PB-written mail client, or do advanced stunt - send all
data except the body text, so mail program is started and cursor placed in
body text window, then find out handle of that window and send the text to
it via a WM_SETTEXT message call or the SetWindowText API.
Should be possible, I think..
------------------
BTW, "LOCAL mText AS ASCIIZ * 50000" only allocates this space within your
program. LEN(mText) is what you actually send.

Eddy, forget my post. I was not awake when I sent it.
Your code is perfectly good. (my minds were at fixed string, not asciiz buffer...)

Lance,
I will check out your suggestion. Thanks!

I begin to believe you are right Borje... So there's no hope for 'mailto:'...

Originally posted by Borje Hagsten:

I thought of that too, but 'mailto:' would have been easier, especially from an unexperienced
users point of view. He does not have to set his mailserver settings etc.
In a PB-written mail client, this would be the case, although not a gigantic problem I suppose.
A question on the side. Would an IT-responsible notice that the mail that is sent from
within his company, is sent by another mail program than the 'normal' mail program in
that company? (OE, Eudora,..) ?

That's far beyond my programming capabilities Borje .
I bet you could do it in a flash...
Anyway, Thanks all for your suggestions!!!

Use 'Byval' StrPtr()

------------------

**Borje Hagsten** · 20 Sep 2001, 12:24 PM

posted a small sample to source code forum that shows one way of doing it.
works fine with my netscape 4.6 here, but no guarantees for other app's.
see: http://www.powerbasic.com/support/pb...ad.php?t=23154

note: in win95/98, there is a 16-bit limit for text length in edit controls.

Borje,
Your sample looks awesome!!!! Will try it with Eudora as soon as I am on my
'PB'-pc !!!
Don't know how you pulled this one out of your sleeve so fast. I bet you
even type faster than you think
Thanks for once again a fine piece of sample code!
Kind regards

borje,
your program does not work with eudora and outlook express.
i changed the idstring. eudora seems to have difficulties with the tabs.
it now works with eudora but still not with outlook express... probably
also not with outlook.. as usual it's the m$ software that gives troubles.
would there be a workaround for oe..?
kind regards

Well, it isn't called "MS Outlocked" for nothing..

I reluctantly started MSO and looked at the class name for the edit part,
and it is "INTERNET EXPLORER SERVER". Seems impossible to reach inside it,
so I guess they have made a real advanced stunt there and encapsulated the
whole thing.

However, there are always ways to fool MS. One can use the clipboard, and
first copy the text and then look for main window handle, plus send a
Ctrl+V to paste the text into the window. Tested here and it worked.

To find MS Outlook's main window, look for classname "ATH_Note" when
enumerating main windows (in EnumWindowsProc). When/if found, simulate
a sendkeys statement, like: (place this at top in EnumWindowsProc)

Code:

  IF hWnd THEN
     LOCAL clName AS ASCIIZ * 100
     GetClassName hWnd, clName, 100

     IF UCASE$(clName) = "ATH_NOTE" THEN
        'Simulate Key Press
        Keybd_Event %VK_CONTROL, 0, 0, 0
        Keybd_Event 86, 0, 0, 0             'V = ASC 86
 
        'Simulate Key Release
        Keybd_Event 86, 0, %KEYEVENTF_KEYUP, 0
        Keybd_Event %VK_CONTROL, 0, %KEYEVENTF_KEYUP, 0
        FUNCTION = 0 : EXIT FUNCTION
     END IF
  END IF
 
'---------------------------------------
' ..and to copy the text to the clipboard:
'---------------------------------------
FUNCTION ClipboardPutText (BYVAL txt AS STRING) AS LONG
  LOCAL cbPtr AS LONG, hData AS LONG, Bytes AS LONG
 
  txt = txt + CHR$(0)                    ' make it an ASCIIz string
  Bytes = LEN(txt)                       ' get # of bytes to load
  IF Bytes < 2 THEN EXIT FUNCTION        ' if no bytes to load
 
  hData = GlobalAlloc(&H2002, Bytes)     ' get memory address of clipboard
  cbPtr = GlobalLock(hData)              ' lock and get pointer to data
  POKE$ cbPtr, txt                       ' paste the text into memory
  GlobalUnlock hData                     ' unlock memory
 
  IF ISFALSE OpenClipboard(0) THEN       ' if clipboard isn't available
    GlobalFree hData                     ' free up memory
    EXIT FUNCTION                        ' Return false
  END IF
 
  EmptyClipboard                         ' empty whatever's in there now
  SetClipboardData %CF_TEXT, BYVAL hData ' point the clipboard at it as text
  CloseClipboard                         ' release clipboard
 
  FUNCTION = %TRUE                       ' return true
END FUNCTION

Can't seem to get it working with M$ Outlook Express.. My programming skills
do not reach far enough I'm afraid.
I think the best thing for me to do is to write an e-mail client in PB.
I probably can use the example that came with PB/DLL.
The advantage is that it is independent of the users e-mail client. The
(perhaps small) disadvantage is that the user must fill in his mail server data.
Anyway, thanks Borje for your time and your example code. I'm sure this will be
usefull for other applications!
Kind regards
Eddy

Finally I have been able to spend some time on my mailto

roblem.
Thanks to Borjes code snippets and tips I have been able to put some code
together that is able to send long mails in Eudora, Outlook Express (!) and
Netscape Messenger.
I have not been able to test with MS Outlook because I don't have it.
Could someone of you who does have MS Outlook please test this program to see if it
works??
This program should open your default mail client, create a new mail and put
some (long) text in the body of the mail...
I would appreciate it if someone could test it with MS Outlook.
Kind regards
Eddy
