Re: Add file to Custom Property

Bill Vlahos wrote: The data will be stored in a different stack. How does that make it different? Where the file is stored doesn't matter. The issue occurs after extraction; you have content in a variable at that point, and almost no apps will open content that is in memory (outside of pasting from the clipboard in some cases.) If you are using the launch command then the file absolutely needs to be on disk. In some cases, if you know what file type the content is and you know which app needs to open it, and if the user has that app on disk, and if that app is scriptable, you can use AppleScript to transfer the content in RAM over to a new document. You may also be able to do the same with a VB script on Windows (but I don't know much about VB, so I'm not sure.) But this approach depends on knowing a lot about the file content itself and the content of the user's drive, and won't always be dependable. Rev has the ability to open stacks from RAM. So the one exception to the above would be if the stored content is actually a stack file. In that case, you can extract it, use the go stack command, and Rev will open it. -- Jacqueline Landman Gay | jac...@hyperactivesw.com HyperActive Software | http://www.hyperactivesw.com ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
Add file to Custom Property
I want to add a file from disk to a custom property, encrypt it, and save it. Then I want to be able to extract the file from the custom property and open it in the appropriate application.

Base64 encoding is a means of taking binary data and turning it into something that can be sent via email, posted to a website, etc (read: no spaces, line feeds, nulls, etc). If you want to actually encrypt the data, you should do that first before base64 encoding it (with the encrypt command). But, you should be aware that the encrypt command requires a password/key, which will also be needed to decrypt the data. While you may be able to encrypt it with the message box or via some other means, you'll need the password/key in a script somewhere to decrypt it... thereby nullifying any hope of secrecy for whatever the data happens to contain.

Re: Add file to Custom Property
Now for the encryption... base64 is not encryption. It is conversion to another character representation, which is easily transparent to most word processors, such as BBEdit, TextEdit, etc. You need to decide what level of security is required.

Re: Add file to Custom Property
The goal is to allow the user to save a file of any format, encrypted, and password protected. Therefore Rev can't be counted on being able to display it. I know I could save the file to disk and then issue an open command but that would leave a copy on the disk. Is it possible to present the file from Rev so that the program (Word, etc.) would be able to open it directly without saving it to disk first? The following example writes the file from the custom property to disk and then launches it: on mouseUp put the uFileStore of button Save File into URL binfile:ScreenShot.png set the filetype to launch document ScreenShot.png end mouseUp Is there a way to skip the writing to disk part and just open it directly?

First, the temporary file can be intercepted mid-operation by a secondary process that's monitoring yours and watching the OS for new open file handles (all easily doable).
