@gnozal: Is there a way to get the entire e-mail into memory? At the moment
if I use PurePOP3_GetMessageTextInMemory() it only gets the body, and I
have to use PurePOP3_GetMessageInfo() to get the rest. It doesn't look like
PurePOP3_RetrieveMessage() gets it all into memory, or can it? Because that
is what I'm after, without having to save it to a file.

PurePOP3_RetrieveMessage() get all the message in memory (as you can see if you use PurePOP3_Trace(#True) : have a look at the PurePOP3-DEBUG* files). I could add a function to retrieve the memory address <PurePOP3_MessageBuffer>. Would this help ?

Yes please.

Micro update (both libs)

- added PurePOP3_GetMessageBufferAddress() function [3 lines of code, not tested]

Thank you gnozal, I can confirm it works great!

Update (both libs)

What's new :
- new function PurePOP3_SetRetrieveCallback(*ProcedureAddress) : set the progression callback address for PurePOP3_RetrieveMessage() ; usefull to indicate the progress when a big file is retrieved.

@Gnozal

I have this email check program, but occasionally (most of the time when having > 15 messages) I get a memory access error.
The error occurs in PurePOP3_GetMessageTextInMemory()

Thanks,
Rob.

Cannot test it until the weekend, but :
- I have tested the lib with > 100 messages with/without attachments and without problems
- In GetThem(), you should FreeMemory(*Message) at the end of the < If *Message / Endif > block

Code: Select all

        If *Message 
          Inhoud.s = PeekS(*Message) 
          Inhoud.s = LCase(Inhoud.s) 
          ;Debug "*INHOUD*:" + Inhoud.s 
          FreeMemory(*Message) ; <---------------
        EndIf

- if this does not help, you could activate the trace mode [PurePOP3_Trace(#True)] and have a look at the PurePOP3-DEBUG*.txt files to help debugging : you can see all the communications and eventually where the crash occurs.

Thank you Gnozal!

I will try what you suggest and report it back.

@Gnozal,

Your solution worked fine, Thanks again!

Hi gnozal, I just noticed that if I turn on "Create threadsafe executable" for
PureBasic v4.00 then I get this error when using your lib:

Code: Select all

---------------------------
PureBasic - Linker error
---------------------------
POLINK: error: Unresolved external symbol '_PB_StringBasePosition'. 
POLINK: fatal error: 1 unresolved external(s). 
---------------------------
OK   
---------------------------

If I remove your lib, or turn off threadsafe, then my app compiles fine.
Don't know if it's a PureBasic bug or something with your lib? I'm using
the latest version of the lib: installer exe of size 88.1 KB (90,275 bytes).

I assume you use the PB IDE.
Did you enable the UserLibThreadSafe subsystem ?

The library exists in two versions :
- the standard version, located in %Purebasic%\PureLibraries\UserLibraries\ ;
- the thread-safe version, located in %Purebasic%\SubSystems\UserLibThreadSafe\PureLibraries\ .
In order to use this library in thread-safe mode (compiler option /THREAD), you have to enable the
subsystem 'UserLibThreadSafe' in the PB IDE, or add '/SUBSYSTEM UserLibThreadSafe' to the
PBCompiler arguments. In jaPBe, do nothing : it will automatically enable the 'UserLibThreadSafe'
subsystem to use the threadsafe versions of the installed userlibraries.

I've never heard of this before, and can't find it in the PB IDE options anywhere.
Where do I find it? I checked the entire "Compiler Options" but there's nothing
there that says UserLibThreadSafe at all.

Edit: Never mind, I just realised to put "UserLibThreadSafe" (no quotes) in
the "Library subsystem" field and it now compiles. Newbies will have fun!

I've never heard of this before, and can't find it in the PB IDE options anywhere.
Where do I find it? I checked the entire "Compiler Options" but there's nothing
there that says UserLibThreadSafe at all.

The %Purebasic%\SubSystems\UserLibThreadSafe\PureLibraries\ directory is created by my library installer. The library in this directory is compiled with my custom Tailbite version with option /THRD. This is the way I use to make thread safe libs [ http://www.purebasic.fr/english/viewtop ... &start=392 ].
It should work (not tested for PurePOP3, but works for PureZIP) with thread safe executables.
You have to enable the subsystem just like you would do it for NT4 or OpenGL. I don't use the PB IDE, sorry.
An easier way to test : replace PurePOP3 from %Purebasic%\PureLibraries\UserLibraries\ with PurePOP3 from %Purebasic%\SubSystems\UserLibThreadSafe\PureLibraries\ and compile in thread safe mode.

In jaPBe, it's automatic !

Yep, that works better (don't need to specify a subsystem anymore). Thanks!
