one way to implement communication between 2 threads is "message passing".

can anyone give me hint to implement it in win32 api?
i guess it is "dispatchmessage" and "getmessage"?

thanks,

Hi List

Someone know or already done a c++ browser plug in with GUI (mean... c++
GUI)? I'm googling around for a couple of weeks and cant find anything
useful.

Another question:
What is the fast way to parse a char[n]? I have a string like that:
L 12/11/2007 - 15:56:45: "x6_Squibles<52><STEAM_0:1:3683971><TERRORIST>"
attacked "x6_scottish<37><STEAM_0:1:1737><CT>" with "glock18" (damage "72")
(damage_armor "0") (health "28") (armor "0")

and like to split in different, say rows in a XML file. I can write the XML
with no problem, but I'm stuck into many loops reading the string, see if I
already pick that value, if, then, for.... well... isn't beauty at all. Its
working, but way too complex.

Thanks in advance.

Good morning,

thank you to everybody, i've solved the problem with the project. 

Thank you

D

Per Westermark,

    I apologize, I did not review my last email before sending it.
    Let me try to elaborate...

    I see some co-relations of my concept with your second paragraph.
    My main idea is to have a internal "plug-in" structure, based on two 
Linked Lists...
    One is a Message Queue, shared by all the "internal plug-ins".

   /** @code : */

   struct Message    {
       char bUrgentMessage;
       long lToPlugin;/** @brief containing signature of the intended plugin 
*/     void* vData; /** @brief Data of variable length and type */
       struct* Message
   }

   struct Plugin    {
      long lPluginSignature; /** @brief Plugin Signature */

      char sPlugin_Name[32];

      int (*Plugin_Constructor )( void **vData );
      int (*Plugin_Main )( void **vData );
      int (*Plugin_Destructor )( void **vData );

   }

   /** @brief  When we created a internal plugin, we would just create a
    static object and assign our own made functions into those pointers, 
then add a line into a function  that does all the loading, creating 
therefore a dynamically amount of internal plugins, by linking them all 
together and in run time cycling through them delivering messages.
   This method also provides me a way to message through my plugins...
   */
    /** ! @code */

   As the exterior plugins are concerned, I am thinking of using an internal 
plugin to load exterior ones... and seek out always the same named functions 
by GetProcAddress() by that is seeming a quite hazardous scheme as I am sure 
to get in trouble if a malicious DLL gets loaded into process...
   Could you advise me on that?

   Maybe I could, as you state, run some of the plug ins in threads... That 
would help me in processing information much faster, as this is designed to 
be a Database Server with HTTP and other capabilities built in . But I am 
not so sure about that shared memory statement. How can I share memory ? ... 
  I do not want to be a CPU hog ( :) )

  I am sorry that I cannot give out any more code... I haven't any, as this 
is mainly a theoretical design.

Too little information given.

You can load plugin modules as DLL files - one or more plugins/DLL.

You will have a hard time protecting your program from ending if the
plugin is badly written. Windows kills broken programs, not broken
plugins. Maybe you can run the individual plugins as separate programs,
but then you must check into shared memory, sockets etc for
sending/receiving data between main program and plugin.

You haven't written anything about how much data each plugin needs to do
it's work. You haven't mentioned how long running time a plugin may
require for a call. You haven't specified expected # of calls/time unit.
You haven't discussed any requirements for concurrent operation of
multiple plugins, or how long time a plugin may consume before returning
(potentially with an answer).

The paragraph "To be clear" is most definitely not clear. It almost sounds
like you are talking about a driver layer either interfacing below the
Win32 API, or between the Win32 API and the plugins. But too little
details and no information about what problem you want to solve.

Hi. I am developing a application, where my developmental concept is a 
hierarchical set of platform.

  I have a platform, at the very start of my tree-like app. This platform I
gave the name "plugin_engine".
  Its basically two Linked Lists, one with function pointers (struct 
Plugin), and the other with data structs(struct Message)...
  The ideia is to itenerate through the Plugin Linked List, and 
subsequentially  through the Message Linked List.
  If a Message ( read "a member of struct Message** LinkedList") is 
designated to a defined Plugin ( read "a member of struct Plugin** 
LinkedList ") we give the control to the plugin main function ( Remember 
that struct Plugin has function pointer members. )

  The first conceptual challange I have is... How to integrate the Win32 API 
into that Plugin platform ?
   To be clear, I wan't my platform at the very first start of the design 
and not as a branch of Win32 Windowing API, so i can also have complete 
control over files/socket operation, and users databases (Also to be 
included)
   I cannot have a critical error that forces my app to break... I wish to 
maintain the most control possible.
  The second is : How can I also create a dynamic plugin structure? Load 
exterior plugins developed for my app?

When compiling, you should have a header file that contains the
declaration for the gcd function. The actual implementation may be in a
separate source file, but the compiler must be able to see return type and
what parameters the gcd function takes.

Do you have any book on C or C++ programming? Dev-C++ uses the MinGW
compiler, but it doesn't matter what compiler is used. The requirements
are specified by the language, not by the specific compilers.

Sorry, i don't want to disturb, i apologize.

I tried to add in a project the three files, but when i compile the proje=
ct i have in output:
26 C:\Documents and Settings\the piper\Desktop\programmi C++\prova.cpp `g=
cd' undeclared (first use this function) 

i know to solve the problem only putting the gcd function inside the head=
er file, i don't know other solution. Do you?

Having read a mail doesn't mean I must answer it. This is a public mailing
list, where people write answers if they want to and have the time.

A little playing around (especially trying out that right mouse button of
yours) should quite quickly give you an idea how to add more source files
to a project. Most integrated development environments tend to function in
regular - and expected - ways, with expected interface methods to perform
standard actions.

Which source files that belongs to a project is very much something that
involves the project. Have you taken a closer look at your project?

Thank you for the information. But how could i link the gcd.cpp file to t=
he project? Sorry but i don't have idea..

thanks a lot

No, there is no zip file enclosed.

On the other hand: how many people do you think bother to look at attached
zip files? Try to manage with just text descriptions of problems, and wait
with attachments until someone requests it.

Anyway, you must add the gcd.cpp file to your project, so that it gets
compiled and linked. The header files are just there to inform the
compiler about available symbols and data types. Including a header file
will not inform the linker what object files that are needed to build the
application.

Good evening everybody,

i have a problem with the mailing list of Dev-C++ and also with this prog=
ram. I'm a C++ student and In my book the gcd.cpp is an external file fro=
m header file localmath.h but if i try to compile the prova.cpp i receive=
 a linker error for undefined link to gcd function., otherwise if i put t=
he gcd definition inside the localmath.h as the abs function everything i=
s correct. Could anyone explain me why? and how could i use the gcd funct=
ion defined externaly from localmath.h without an error? 

the programs are in the zip file enclosed.

thanks very much to everybody

I am attempting to learn how to use Win32 to create a GUI program but am having problems with the Dialouge boxes. 
   
  Here is what I have done so far (the dashed line seperates files)
  ---------------------------------------------------
  Resource.h
   
  #define IDD_DLGFIRST 101
  --------------------------------------------------------
  Wind32D.rc
   
          
#include "Resource.h"    IDD_DLGFIRST DIALOG 260, 200, 188, 95  STYLE DS_MODALFRAME | WS_POPUP | WS_CAPTION | WS_SYSMENU  CAPTION "Win32 Programming"  FONT 8, "MS Shell Dlg"  BEGIN      DEFPUSHBUTTON   "OK", IDOK, 130, 10, 50, 14  END

  ------------------------------------------------------------
  Then, when I try to compile the program, I get an error.  Included below is the text from the compiler tab, Resources tab, and Compile log.
   
   
  C:\Documents and Settings\Bradley\Desktop\Win32\Project5\Makefile.win

How to implement the "let the RS232 thread send message to the GUI thread"
for updating the GUI?
Can you give us a pseudo code for it?
I guess you will formulate a message in RS232 thread, then let the GUI
thread to get this message by PeekMessage().  ??

I agree that "you normally don't generate an update event every character".
So I am thinking to generate an update event every message.  I mean, after I
get the whole message (including end-of message character), I am thinking to
give out an indication to GUI that we got an full message.  What shall I do
for it? Do I need to set a flag here to give out this kind indication? OR
win32 API provide us functions to do that?

If I want to use RS232 thread to receive data, and GUI thread display data.
Do I need create two buffers in RS232 thread?
Back-end buffer is used to receive data, while front-end buffer is used to
provide data to the GUI thread.
What is the basic (classic) design for this problem?

===============
One alternative is to let the RS232 thread send messages to the GUI
thread. Either with the serial data, or just as information that there are
serial data available.

Yes, Google is very good at showing example code.

Remember what Dev-cpp is only ID.

1. U need create socket by old_socket = socket(...)
2. bind(old_socket, ...).
3. new_socket = listen(old_socket, ....)
4. recv(new_socket, buf, buf_length)
5. do something with buf.
6. close both sockets;
7. another turns.

I'm not exactly getting how this would work. Would anyone 
perhaps be able to show me example code for this?

i met that problem before.
because i have Eclipse CDT(based on MinGW) and Dev-cpp both installed in my
system.
after i un-installed Eclipse CDT , and re-installed Dev-cpp, Dev-cpp works
fine.
i think the problem is dev-cpp and eclipse cdt conflicts each other.
anyway, try to firstly un-installed any other stuffs about MinGW, then
install  Dev-cpp to see.

Oops.. I'm terribly sorry...

I got two books mixed up.  You want _Numerical Recipies_ in C (freely
downloadable, IIRC), not Thinking in C.
