Hi Goran,

After many hours of frustration I've come to the conclusion that the 
default wxWindows 2.2.9 package will not work with Dev-C++ 4.7.9.x/gcc 
3.2.  I believe you have two choices:

1)  Use Dev-C++ 4.7.9.x/gcc 2.9.5.  A fresh installation will allow for 
a build of the provided example.  Should you install the upgrade for 
v4.7.9.1, be sure to copy and paste the "Compiler" flags to the "C++ 
compiler" list box (under Project Options->Compiler->Compiler Options).

2)  If you want to use the gcc 3.2 version, I could find only one 
solution:  build a new wxWindows lib from the source provided at the 
official wxWindows web site (located at 
http://www.wxwindows.org/dl_msw2.htm).  This was actually a 
frighteningly straight-forward procedure, except that that a debug build 
of the library will not work -- an executable linked against such will 
report a library mismatch.  I used the 2.3.4 snapshot and built a 
Unicode release-level static lib and all appears well.  Be sure to 
remove the existing wxWindows package and perhaps even the "Image 
Library" package as the wxWindows source includes that for libpng, 
libjpeg, libtiff, and libzlib.  Otherwise, watch out for lib 
conflicts...  In addition, you'll have to perform the aforementioned 
compiler flag copy.

Good luck to you.  If you need any further help, I'll be happy to 
provide it.

Marshall

Hi,

Thanks for your prompt responses!

I should have mentioned in my earlier that I did try adding the -lwsock32
option to the linker command line.I tried it once again though and the
result was the same as before.The undefined reference error to WSAStartup
error still shows up.

Also I would like to run this a stand alone  file (not a project). Any
suggestions?
Thanks in advance once again for your help.

Just because a file is present in the `lib' directory, doesn't mean that
it'll be linked in. You need to add it to your the list of libraries the
linker must add. Add `-lwsock32' to the linker command-line. Any lib by the

    Just add "c:\Dev-c++\Lib\libwsock32.a" (supposing you have Dev-c++

[Dev-C++] Trouble compiling winsock programs.

[Manoj S. <sha...@ro...>]

Hi,

I am trying to compile a simple winsock program using Dev-C++ and get the
following error
[Linker error] undefined reference to WSAStartup@8. I tried generating my
own libwsock32.a   library using the wsock32.dll on  my system with the help
of the dllwrap utility and linking it to my program by copying the generated
.a file to the lib directory but the error stayed the same.

I also tried using an older version of wsock32.dll (since I have the latest
version of the dll) and it may not be compatible with the header files as
supplied by Dev-C++. But this gave me the same undefined reference error.

As a last resort I tried using the header files supplied by the Microsoft
SDK instead of the include directory header files as supplied by Dev-C++. I
get a target architecture must be defined error. An attempt to #define
_M_IX86 which is the macro that needs to be defined leads to further errors,
so I would prefer not to go down that path further.

Can anyone suggest what else can be done to get a very simple winsock
program to work. I have the XP OS on a Pentium machine.

Regards,
Manoj.

LOL!
first: for such questions you should use genereal discussion groups,
this one is dedicated for DevC++... if you are form Poland (tak jak

char strInfo[ 100 ];
float fPi = 3.1415926;
sprintf( strInfo, "%f", fPi );
remember to include <stdio.h>

and if you really want to use string class then do this similar to

Subject: [Dev-C++] trim / sub string


Hi,

Another problem to solve.. i wish to make a routine which gives me a
substring or trimmed down on the following
conditions that i can start from anypoint in the string untill the offset is
reached. so for example

mytext = "this is a test";
result = substring(mytext,6,2);

result would now have to contain the 2nd word "is"...

--------------------------------

You can use pointer arithmetic to reach characters. For example,
    mytext + 5
will access the string from `is' onwards (uptil the NULL character).

To copy it into another buffer, you need to copy from the above location
until the number of characters specified have been exhausted. For example,

char *substring(const char *orig, char *buf, int offset, int len)
{
    for(unsigned i = 0; i < len; ++i)
        buf[i] = orig[i + offset];

    buf[i] = 0; // NULL terminator
    return buf; // For convenience
}

This is a zero-based function, so

mytext = "this is a test";
substring(mytext, result, 5, 2);

Would give a resultant buffer containing `is'.

HTH.

[Dev-C++] DevC++ & wxWindows

[Goran K. <go...@em...>]

As a result of past years experience and current demmands I came to a
decision to use DevC++ and wxWindows to have a multi platform development
environment.

I had some problems using DevC++.4 I added some defines(like -D__WXMSW__)
patched some *.h files (I know it's not the supposed procedure) in order to
make some projects run.
 But it become almost imposible when I came to the point of using wxWindows.
When if finally mannaged to compiled it failed to link(wx32.lib) It failed
also with BCC5.5 because was no wx32.lib on the disk.
 After that I tried to recompile wxW but failed on some parser.y file. Then
I gave up.

I tried on W2k and later on a plain Win98. I also downloaded DevC++5(4.9.7.0
with gcc 3.2), but this doesn't compile even added examples. Another try was
Detlev Reymann's page "wxWindows and Dev-C++" - failure again (not blaimming
Reymann anyhow). Currently the machine has installed DevC++ 4 and 5, Borland
C++ 5.5, mini IDE, small IDE, VIDE, Chimera IDE, Mingw 2.0 with gcc 3.2.

Anyone has some idea or procedure how to install and setup DevC++ 4
(preferably 5) in order to work with wxW?

funny *function stuff? Does it means say funny *function; and then
function = new funny[number]? I do it. (No spam)

   >Then inside another function:
   >int cuantos = rand() % 19;
   >(this->*function[cuantos])(NULL);

   >NULL is deprecated in C++. Also you forgot some parenthesis. You

   >(this->*classname::function[cuantos])(0);
The parenthesis are there.


I didn't say all functions are private.
I used the modifications you pointed, still access violation, when 
calling the function.
...
cout << "Here!" << endl;
(this->*(classname::)cion[index])(param);
...
The output:
...
Here!
Program.exe has generated errors, it will be closed by windows, you'll 
have to restart it.
I tried some compiler options (-vtable-gc, and other) but no resul.

Re: [Dev-C++] rookie question... Getting the current directory

[<or...@vp...>]

Hello!

> Windows uses GetCurrentDirectory()
Well, you have to be careful with this function, because it not always gives the 
directory, where the program executable is! Whenever you press enter (or 
double-click) on a file, which is associated to your program, then the current 
directory will be the dir, where the associated file is, NOT the dir of your 
exe! This can be annoying, when you want to write config-files. To retrieve your 
programs path, use __argv[0]. This contains the path to your program (for 
example: "C:\myprog\myprog.exe"). The other __argv[] elements contain the 
command-line arguments.

Hope that helps.

[Dev-C++] Problems with function pointers inside a class

[<cg...@wo...>]

  Hi:
I am trying to use the title of the message.
I declare:
class{
...

typedef void (classname::*funny)(void**);  //I tried either void 
(classname::*function[19])(void**);
funny *function; OR funny function[19];
};

Then
class::class(){
function = new funny[19];
function[0] = &class::function1_name;
:
function[18] = &class::function19_name;
}


Then inside another function:
int cuantos = rand() % 19;
(this->*function[cuantos])(NULL);
                                           ^-- Or &void_pointer_*,  or 
void_pointer_**, or (void**)int_pointer_**, set to NULL or not 
initialized or initialized.
I read this is the correct way for doing this, and 
(this->*function[cuantos]) is the only syntax the compiler accepts.
When it's time to use the function it crashes.
Right now all the functions are:

void class::functionx(void** tas){
cout << "functionx" << endl;
}

What I see in my code is done as "Thinking in C++" says it must be done.

----------------------------

Windows uses GetCurrentDirectory()

------- From docs ---------
The GetCurrentDirectory function retrieves the current directory for the
current process.

DWORD GetCurrentDirectory(

    DWORD  nBufferLength, // size, in characters, of directory buffer
    LPTSTR  lpBuffer  // address of buffer for current directory
   );
Parameters

Return Value

If the function succeeds, the return value specifies the number of
characters written to the buffer, not including the terminating null
character.

If the function fails, the return value is zero. To get extended error
information, call GetLastError().

If the buffer pointed to by lpBuffer is not large enough, the return value
specifies the required size of the buffer, including the number of bytes
necessary for a terminating null character.

<iostream.h> is deprecated. The latest C++ standard specifies using
<iostream> along with namespaces. cout, cin, cerr, all standard library
functions are in the `std' namespace. To access them, you would say
std::cout, or std::cin.

So your hello program would be

------- Start -------
#include <iostream>

int main()
{
    std::cout << "Hello, world.\n";
    return 0;
}
------- Stop -------

However, when you run it directly from the IDE, or from Windows explorer,
you won't see any output. Run the program from a console, or see the FAQ.
