[Dev-C++] error messages

[<h.r...@gm...>]

Hi List,

what is the meaning of the following error message:

19 showres.cpp
request for member `TI' in `arh', which is of non-aggregate type `arrhenius
()()'

the line in which the error occurs:

void showres()
{
  extern arrhenius arh();

  cout << "TI  = " << arh.TI  << endl;  
 [...]

TI is a public member of arh. 

The constructor of arh:

arrhenius::arrhenius(int gr, int smpl)
{
[...]
}

Whats wrong ???

Thanks in advance
Horst

[Dev-C++] Allegro Help

[B. P. <nu...@ho...>]

I tried installing Allegro for the Dev compiler, but I keep running into an 
error. I added 'c:\dev-cpp\bin' to the beginning of my Environment path(I 
used the default directory to install on my XP machine) and added 'set 
MINGDIR=c:\dev-cpp' to my autoexec.bat. When I type gcc -v in the command 
prompt I get a respose that it is reading the stuff.  However, after I 
'fix.bat mingw32' in the allegro directory and type 'make' it gives me an 
error saying:
"Please specify your MINGW32 directory via MINGDIR=
See the docs/build/mingw32.txt file!"

RE: [Dev-C++] NT 5.0 Passwords

[Ioannis V. <no...@ho...>]

It doesn't sound feasible. Presumambly he refers to a network connection
from UNIX. Now if UNIX is installed on the same system as NT and can
mount the file system so as to be able to write on it and knowing the NT
internals (e.g. the algorithm used to encrypt/decrypt) he theoretically
can do that. However the files encrypted with the EFS of NTFS using the
previous key would not be cracked.

 So for summary, to change the admin password you must know where to
write, what encryption algorithm is used and the access to write.

[Dev-C++] NT 5.0 Passwords

[John P. <jpa...@ya...>]

Hey guys,
I was talking with some guy and he had told me that he can hack into a NT
5.0 system (and previous versions) using a Unix script that allows him to
write his own password. Is this possible. Can he access a password protected
box and rewrite the password to suit him, if so how does he access the box
in the first place to do it. I don't think it is possible. Let me know what
you guys think.

This isnt a dev-C++ specific question, but i am wondering if anyone
knows how you check if a float or double carrys valid data. 
 
My program runs fine most of the time but every now and again it spits
out -NaN.
I figure its from uninitialised variables, however I cant track down
where they enter the program without performing periodick checks at
suspect locations. 
 
So is there a function like 
    bool validFloat(float num)  for instance?

Here a function from the open SciLab system (matlab clone)

int mxIsNaN(double x)
{
  if ( x != x ) 
    return 1;
  else return 0;

[Dev-C++] Still can't open the application

[<Bha...@cs...>]

Yesterday I downloaded the Dev C++ application twice. It gave me the error 
message for the frist download, so I did it again by downloading file 
devcpp4290, the 9465kb application. It appeared to download successfully but 
gives me the following error message when I click on the application using 
Windows Explorer:

NSIS ERROR       
Installer verification failed   

plus text with possible reasons for the failure including a virus, incomplete 
download and failing disk. I ran McAfee which said the file was clean.

At Ioannis' suggestion I downloaded memt2.9 today, unzipped it and ran it for 
5 passes with no errors reported. Apparently my CPU memory is OK. Thanks for 
the suggestion though, Ioannis.

The NSIS error message also said I could try to force the installation of the 
application using the /NCRC command line switch, but recommended not doing 
that. I don't know how to do that anyway. 

Any suggestions on how I can get the application to execute would be great. 
Should I download it a third time?

If you compile with Borland using the AT switch, i am sure it will not
compile either:

E.g. bcc32 -AT temp.cpp


-AT forces ANSI compatibility.

Re: [Dev-C++] QUESTIONS FROM A NEWBIE

[Jason H. <jas...@bt...>]

I'm not familiar with Dev C++ 4.9.2, but check that you are compiling for a windows program (or
console if you need to).

Windows uses the backslash character '\' and you can use short (8 char) or long filenames in Win 98
etc...

I am very much a C++ newbie trying to get up to speed! I hope I can bother
you for a few answers.....

I have just started with Dev C++ 4.9.2. When compiling I am getting errors
like:

7 //C/MYPROGS/FLTKTest/Hello1/Hello1.cpp
undefined reference to `Fl_Window::Fl_Window(int, int, char const *)'

As far as I can see I have properly included headers etc and nominated the
correct library/header etc paths in Dev C++, so I am not sure why these
errors. A number of questions:

1. I am running on Win 98. Am a bit confused about whether to use / or \ for
file path separators in my source code and also include paths in Dev C++
IDE. As far as I understand, UNIX and DOS use different separators.

2. Do I need to keep my directory names to 8 characters or less with no
spaces? (again a carryover from DOS or UNIX).

3. Is there any documentation listing the error messages and explanations
for DEV C++?

[Dev-C++] (Possible feature request) - using a wildcard (*) when specifying include file and libraries directories

[Andy E. <and...@pa...>]

Hi all .  I've been mulling this over for a while, so I thought I'd see =
if anyone else would like this feature ... (just btw, I'm using Devcpp =
4.0 under Win98 ) . =20
 In the "directories" section of "compiler options" , you can specify =
the directories to be searched.  What I would find *really* useful would =
be if I could use a wildcard (*) to specify that *all subdirs* under =
this directory should be searched as well.  For example -=20

 "C:\devcpp\foo\; C:\mydir\* "

  This would be a lot more concise than doing what is needed at the =
moment, i.e. , something like -=20

 "C:\devcpp\foo\; C:\mydir\subdir1; C:\mydir\subdir2\; =
C:\mydir\subdir1\anotherdir\ " ...... (and on and on .... :-)=20

 One of the biggest hassles in compiling programs is when files can't be =
found (arrgh) , so allowing the use of a wildcard like this would be =
_really_ useful .    Is there *anyone else*  who'd like to see this?  =20
 ( As an aside, if this _weren't_ to be implemented , maybe someone can =

[Dev-C++] Resource: WASP Server for C++

[Yeoh H. <ye...@ye...>]

<begin extract>
WASP Server for C++ is a small, embeddable solution that brings the
advantages of Web Services to the world of C and C++. A flexible runtime
framework based on standard SOAP and WSDL ensures seamless integration with
existing solutions. WASP Server for C++ also includes a number of advanced
features that set it above the competition, including security, rich type
mapping, extensibility, remote references, extensibility, and portability.

WASP Server for C++ performs dynamic and automatic data type mapping between
C++ and XML, supporting simple and complex datatypes and objects.

WASP Server for C++ supports a variety of configuration options and
extensions. WASP services can run stand-alone, or they can be deployed
within a Web server. The environment supports custom datatypes, custom
encodings, custom serialization modules, and custom authentication and
authorization mechanisms.

A feature unique to WASP, remote references allow a Web Service to pass a
reference to another Web Service over the SOAP. Remote references are
critical to many distributed computing design patterns, particularly the
Factory pattern, which is used in many enterprise-class application systems.

WASP Server for C++ comes with a convenient API and a set of command-line
code generation tools that give developers a strong foundation for building
portable Web Services. WASP Server for C++ is supported on Microsoft Windows
CE/95/98/NT/2000/XP, Linux, and Sun Solaris. The core SOAP stack is
available as Open Source, allowing users to port WASP Server for C++ to
additional platforms as desired.

Re: [Dev-C++] enum

[Graeme F. <gr...@dr...>]

Assigning values to an enum has (under certain circumstances) great value.
If you have set up an enum in a binary escalating scale (1,2,4,8,16 etc) and
you also wish to use it in a loop then use the bitwise shift operator as
follows:

#include <conio>
#include <iostream>

enum state {none = 1, open =2, modified = 4, deleted = 8};

int main(int argc, char* argv[])
{
   for (int i=1; i<=deleted; i<<=1)
   {
      std::cout << "did something\n";
   }
   getch();
   return 0;
}

Now it is possible to loop through each state and do something as well as
use logical operators to combine the different states using the bitwise or
operator, e.g..

fileState |= modified;
