RE: [Dev-C++] _outp & _inp under windows 2000

[Santiago P. C. <San...@yd...>]

Hi Per, Mark and *,

I know that there is no portable way for __low-level__ access to I/O port=
s
due to OSes differences, but I thought we were talking about some kind of=

__high-level__ I/O port access...
BTW, it seems to me that we were talking about accesing 'common' I/O port=
s:
COM, LPT... from a console program, not creating a low level access drive=
r
for any OS nor accessing special/rare/propietary data acquisition HW,
weren't we?

So that's why the wxCTB exists, it is not a device driver but an attempt =
to
create a portable __high-level__ (like the rest of wxWindows itself and i=
ts
contribs) communications package.=20
We must say that, like all free/open source/etc projects, it is still bei=
ng
actively developed, so while being completely functional for a lot of
situations, it is not complete by now...

Anyway, this library (provided as a contrib package for wxWindows) uses
internally separate low-level access code for Windows & Linux (the only 2=

platfforms currently supported), but provides an external 'common' unique=

interface for high-level access, that's why I think it would be a good
solution ;o)

OTOH, it seems to me that the app is accessing (from a high-level approac=
h)
a 'common' I/O port (probably a serial one) because Mark Smith has the
source code of the 'data acquisition SW', don't you think so? It would be=

very strange to have the source code of an app that accesses some propiet=
ary
interfaces or special device drivers...

So the real question is: What kind of I/O port does Mark Smith really nee=
d
to access? And how? ;o?

Best regards,
~Santy

Old data acquisition software written for MsDos, Win 3.1, Win95, Win98 et=

Hi,

I want to use libmySQL.DLL with dev-C++ and after reading some docs...
I use :

I add alias and@xx needed to the libmySQL.def
dlltool --dllname libmySQL.dll --def libmySQL.def --outputlib libmySQL.a
I copy libMySQL.a into c:\dev-cpp\lib

But when I buid my project I continue to take a lot of error like that:

mysql_1.c undefined reference to 'mysql_connect@16'

What is wrong? 

Thanks for help,

Daniel

Well, writing the configs is the easier task. Parsing them is hard. Actually I 
wanted to achieve the following:
  - sections, like [Section1] etc.
  - single line data, like Value=data
  - (!)multi line data. This is the hardest to parse. You need to convert the
    given string, when you write, because when you read, you need to know,
    where to stop. I thought of the following: (using '\' at the end of the line)

MultilineData=This is a multi \
line data. \
\
And may contain empty lines, like above. \
Stop here

Data2=
...

I would need something like this for my project, but I have no time to implement 
a complete new library, and make interface for it. I have already made 3 
independent libraries. Now the parser is "hacked" (hard coded) into my project. 
If I have time, I will make one (or extend yours), and post it to the list.

Anyway, the libraries, what I have already made:
xstring - A string manipulation library for C. C handles strings awfully, 
actually it doesn't even has strings, just char arrays, which is the source of 
many errors. strcpy() and similar functions can easily freeze your program. This 
is the reason for the existence of this library. Luckily C++ already has strings 
built-in, so it is recommended for "C only" users.
list - simple, fast doubly linked closed list implementation, which may be 
sorted or unsorted given a cmp function (like to qsort()).
error - last error handling library for single threaded apps. Register last 
error codes, assign error messages to them, set, get last errors.

If you need them, let me know.

Thanks anyway.

I was aware of that, I just didn't know, how much is the maximum. I think DOS

Yes, I knew that. Actually I wanted to know, how much memory can I get from a 
DOS program, that is running under Windows, from a console. As I saw in the 
command-prompt settings, the memory can be set for the console.

Thanks, although I have already heard of that too, but I don't really want to 
develop anything for DOS. I suppose I would be able to use djgpp with Dev, I 
would just need to set the compiler executables.

No problem, but thank you very much. I only needed the answer because I went to 
a Secondary (High?) School Programming competition(?) (yet I'm only 17 :), and 
they still provide Borland C++ 3.1 for programming.

Hi *,

You can consider porting your app to wxWindows, it is not only a GUI
library, it is a complete portable framework.
You can use the latest wxWindows stable release (2.4.0) and wxCTB
communications package by Joachim Buermann (http://www.iftools.com/), it =
is
not GUI based so it can be used in console apps.

It's an "easy" way to have a portable app that accesses I/O ports...

I think that you can't.
Only SYSTEM level software can access directly the I/O ports, all other 
software can only open it as a file [and is not a great method, i tried 
it for one program].

[Dev-C++] _outp & _inp under windows 2000

[Mark S. <mar...@li...>]

I have some data acquisition software which runs OK on win98 but because you
cannot address the hardware directly with win 2000 it wont work, It is a
console based application,  is there an easy way for me to modify the code
so it will run under win 2000?
An example would be most helpful. I'm a console only app man at this moment.
TIA
Mark

[Dev-C++] to include "winbgim.h" in Dev-C++ 5 ??

[Ricardo R. <ri...@po...>]

Dear Colin and coworkers,

perhaps it would a good idea to include the
header "winbgim.h" and the library "libbgi.a"
 in the new version of Dev-Cpp to work with graphics
easily and to portate the graphical programs done
with the C++-Borland compiler.
What do you think?.

Ricardo.

winbgim. Do a search for it.

You could also use the registry settings.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\IEXPLORE.EXE

Re: [Dev-C++] Creating a .DLL

[Abhijit S. <mu...@gm...>]

Greets, Duncan.

This site may help:

http://webclub.kcom.ne.jp/ma/colinp/win32/dll/make.html

It tells you how to create a DLL using the command-line. You'll have to add
the options to your project.

In DOS (real-mode), memory is banked. So you need two thingies to address
it: the segment and offset. To make a pointer, given segment and offset, use
MK_FP(seg, off) and to find the segment and offset of a pointer, use
FP_OFF() and FP_SEG().

The segment is like a bank (they overlap, however), and the offset is the
memory location within the segment. Search on Google for more info. Or see
the X2 FTP, it's got a treasure-trove of info about MS-DOS programming:
http://sunsite.lanet.lv/ftp/mirror/x2ftp/msdos/programming/

However, in most general applications, you won't need to bother with them.
You simply call new or malloc(), and they return an appropriate far pointer
(depending on the memory modely you're using - small, tiny models don't use
far pointers). Only if you're doing some hardware-level stuff, you'll need
to bother with segments and offsets. In small, tiny and medium models, I
think you get 64k memory (a 16-bit pointer), and in huge, large models you
get 1 meg (a 20-bit far pointer). The other differences in these models are
the size of the data segments and global heap (I think... long time no
real-mode).

Also, in protected-mode DOS (DPMI), memory is linear. Use djgpp:
http://www.delorie.com/djgpp
for this, its a GCC port for DPMI. It's also got an IDE similar to
Turbo-C++, called RHIDE. You may or may not be able to use it with Dev. If
you're successful, post to this mailing-list for the welfare of humanity and
stuff.

HTH, and sorry for the late reply.

You'll have to do a recursive search on all available disks, or, if you want
to save time, only on the primary disk (the one with windows - use
GetWindowsDirectory() for identifying it), using FindFirstFile() and
FindNextFile().

Note that, though spawn(), exec(), system(), WinExec() etc. will work, they
are not the most efficient ways of executing external processes on Windows,
CreateProcess() is.

See my (basic) helper class:
http://mudeth.tripod.com/rsearch.htm
for reference.

Hi again ,

 Something like this :


************************************
#include <process.h>


 char *my_env[] =
{
   "Environ To Pass",
   NULL //pass sytem environ
};

char *my_Prog ="iexplorer"; //program to launch
 char *args[4]; // arguments for my_Prog






 _spawnvpe( _P_NOWAIT , my_Prog, args, my_env );

**************************************
  
 Hope it works .

I don't have the answer but to launch an URL I use (in C++Builder but its 
Windows stuff so it may work in Dev-CPP) :
  ShellExecute(Handle, "open", MyURLToLaunch, NULL, NULL, SW_SHOWNORMAL);

[Dev-C++] Interactive screen-saver

[Philippe de R. <phi...@ww...>]

Hello,

is there a way to make a screen-saver interactive? For instance, I 
would like to let the user click on text displayed on it without the

[Dev-C++] How do you find a file's path?

[Philippe de R. <phi...@ww...>]

Hello,

I have developed a basic application using C++-Dev that creates a 
process that runs IExplorer. Unfortunately, CreateProcess will not 
launch IExplorer unless I specify the latter's complete path (e.g., 
C:\program files\Explorer\ieexplore.exe) as second parameter value: 
CreateProcess( NULL, "C:\\Program Files\\Explorer\\Iexplore.exe", ...). 
I would like to search for IExplorer on the user's PC before creating 
the process. What is the easiest way to do that on Windows?

Many thanks.
