Open Closed Stack Still in Memory
Aloha, Opening downloaded a closed stack in memory (i.e. not destroyed) that was downloaded but never saved to disk has some unusual behavior. Scenario: -- Boot Stack A, -- Button in Stack A downloads Stack "Portal" from the web -- Stack "Portal" has a button that downloads Stack C and then closes itself (but stack "Portal" is never saved to disk) -- We want stack C to auto open stack "Portal" when it closes According to documentation, Stack "Portal" is still in memory if not destroyed. . . But on closeStack open stack "Portal" #using the stack's filename end closeStack Doesn't open it. One could presume this is because it was never saved to disk and therefore has no path as such. Is there a way around this? Also I close stack "Portal" but not destroy it and then download stack "Portal" again, I don't get any message telling me that Stack B is already in Memory and if I want to purge the previous one or not. . . But then I solved the problem by a) not unloading Stack "Portal" after it arrived b) storing the hRef of the Stack "Portal" into a global gPortalhRef c) closing Stack "Portal" (one could also query the cachedURLs) Now, we can re-open stack portal anytime (assuming we never exit) with: global gPortalhRef on mouseUp go url gPortalhRef end mouseUp OK, fine, but can someone explain the two different behaviours in more explicit terms? Is there a way to go to the cached stack more directly? One would rather not have to globals or keep having to query the cachedURLs, although that is certainly doable if it is the only way. Is stack "Portal" in memory or not? Is the http "cache" in a different place in MC's heap space? Or is it placed in a ram sector outside of MC's heap space? The second issue (besides direct access to open the stack from memory) being how far can you go with this before you better make sure you start unloading some URL's .

Re: Emailing an attachment
on 7/16/2000 1:11 PM, andu [EMAIL PROTECTED] tried to help me with my problem below: I am trying to send an attachment file with the mcmail.mc file. So far, this is what I have done: I put a field "theAttachment" into the card. The script is from the button "Send", with my addition clearly marked. It does something, but it doesn't place it as an attachment, but as a part of the body text. # construct email header put "" into mailraw put "From: " fld "mailfrom" crlf after mailraw put "Date: " mimedate() crlf after mailraw put "Content-Type: text/plain; charset=us-ascii" crlf after mailraw put "MIME-Version: 1.0" crlf after mailraw put "Message-Id: " the seconds "-" the ticks "@MetaCardSMTP" crlf after mailraw put "To: " fld "to" crlf after mailraw if fld "cc" "" then put "CC: " fld "cc" crlf after mailraw end if put "Subject: " fld "subject" crlf after mailraw put crlf fld "body" after mailraw -- ** MY ADDITION if fld "theAttachment" is not empty then put fld "theAttachment" into theAttachmentName Try put url "binfile:" theAttachmentName into theattachment put crlf "Content-Type: application/base64; name=" quote \ theAttachmentName quote after mailraw put crlf crlf base64Encode(theattachment) after mailraw I tried it. Still doesn't work. It does do something different, though (I'm not sure exactly why...). It seems to encode the name, but not the file. But thanks. Still working on it. Any other suggestions? put "binfile:" theAttachmentName into theattachment put crlf "Content-Type: application/base64; name=" quote theattachment quote after mailraw put crlf crlf base64Encode(url theAttachment) after mailraw end if -- # socket implementation, talking to smtp smtpsend fld "smtpserver",fld "mailfrom",validEmailList,mailraw end composemail -- I sent the file (a MetaCard file) to myself. I copied and pasted the encoded data in my email into a MC field. A button has the following script: on mouseUp ask file "What file to save to?" put it into thefileName put base64Decode(field "thebinfile") into URL thefileName end mouseUp But now, when I attempt to open the file (type into the message box "Answer file "?"; open it), I get the message "stack was corrupted by a non-binary file transfer" - So, any suggestions? I really *need* to be able to send file attachments with this MCmail protocol. I am building an app that will generate a MC stack, then email it to the appropriate person.

And finally add the following for your attachment: # the attachment header put "--TheMailBoundary" crlf \ "Content-Type: application/base64; charset=us-ascii" crlf \ "Content-Disposition: attachment; filename=" quote \ theAttachmentName quote crlf \ "Content-Transfer-Encoding: base64" crlf crlf after mailraw # the attachment base64 code put base64Encode(theattachment) crlf after mailraw # closing the email put "--TheMailBoundary--" after mailraw -- ** MY ADDITION if fld "theAttachment" is not empty then put fld "theAttachment" into theAttachmentName Try put url "binfile:" theAttachmentName into theattachment put crlf "Content-Type: application/base64; name=" quote \ theAttachmentName quote after mailraw put crlf crlf base64Encode(theattachment) after mailraw I tried it. Still doesn't work. It does do something different, though (I'm not sure exactly why...). It seems to encode the name, but not the file. The point here is to create a multipart MIME mail. If you refuse to read RFC document, you can just grab a sample source of email with attachment. Note that used of static "TheMailBoundary" here wasn't a good idea, you should change it to a random generated string. I have tried the code, so be careful. Hope this helps.
