mailto: error

I'm triing to give my users several different ways to send mail from my app.
One of it is the mailto: command that is send by ShellExecute()

When sending the mail it works well for small mailbody's

When the mailbody is bigger there is a VO error.
Are there some known limits on this ?

I use

ShellExecute(NULL,String2Psz("open"),String2Psz("m ailto:x@y.com"),NULL,
NULL,SW_ShowNormal)

so the 2nd argument differs, and there's your error.

Dick,

IF ShellExecute(NULL_PTR, String2Psz("open"), PSZ(cShell), NULL_PSZ,
NULL_PSZ, SW_SHOWNORMAL) == NULL_PTR

Gives the same error on the same line with the same VO-error
Error Code: 50 [ ]
Subsystem: VO-CODE

A problem with a big email and not a smaller one would lead me to look for
something preceding this that is screwing up memory. Bigger email could
cause GC, that a smaller one wouldn't.

Some people have been using CreateProcess rather than ShellExecute.

Finally, the first parameter is looking for a window, the code that Dick
posted used a NULL rather than a NULL_PTR, any difference? (You can see my
background is Clipper...and not C <g>.)

others have previously reported limits on shellexecute with mailto:
but I thought they reported it simply not working (basically
it looked like either a mailer limit or a commandline limt)

Dick,

can you try the following:

IF ShellExecute(NULL_PTR, String2Psz("open"), String2Psz(cShell), NULL_PSZ,
NULL_PSZ, SW_SHOWNORMAL) == NULL_PTR


If cShell is a VO string, PSZ(cShell) could be the reason for the error.
Try String2Psz(cShell) instead.

Sven

Sven/Marshall,

IF ShellExecute(NULL, String2Psz("open"), String2Psz(cShell), NULL_PSZ,
NULL_PSZ, SW_SHOWNORMAL) == NULL_PTR

Still gives the same error.
When I make the string cShell smaller it works. There seems to be no
relation to the chars in it but on the size.

CreateProcess(NULL_PTR, String2Psz(cShell), NULL_PTR, NULL_PTR, FALSE, 0,
NULL_PTR, NULL_PTR, @startup, @pro_inf)

Always returns false when using mailto: as the start of cShell

There is an issue like less 200 chars for Windows 98 I have found.

John,

I gave up on Shellexecute() for attachments to the default mail handler.
If I have to send attachments I use SMTP or Outlook or MAPI.

Phil,

I think I'm going to use SMTP as well.
MAPI is my default solution but some users that have strict safety policies
or less compatible mail clients do not get MAPI working.
