[Dev-C++] Doble pointer

[Esteban V. <est...@ho...>]

Hi, I can do this:

int array [ N ];
int *p = array;

but I can't do this:

int matrix [ M ] [ N ];
int **q = matrix;

An "suspicius pointer conversion" warning message appear and the program
halts when I run it. Why can't do this assigment ?

Re: [Dev-C++] Two compilation bugs

[David M. <dem...@uw...>]

Another bug is with the class browser - when view projects with hundreds of
entries, the names go all weird (see the JK2 source code, or many other
large msvc imported projects.)  Turning off 'view colors' fixes that, but
it's annoying.

Another class browser issue - if you have any prototypes in another file,
it will add those to the list as well as the original, making doubles of
each function.

If the Herbert Schildt book is the spanish version of "C: The Complete
Reference" then there's a much newer version from 2000.

This code compiles. Find the differences. :)



template <class T, int optimum>
class CConteiner
{
};



class CScene{};


class CScenes:public CConteiner<CScene*, 4>
{
};


int main()
{
}

you can't access hardware without writing a device driver in win2k/xp.

try http://www.driverlinx.com/DownLoad/DlPortIO.htm (it works)

[Dev-C++] ARGV PARMS FOR CGI

[<jim...@es...>]

Hi Folks.

  I'm experiencing problems in reading the argv[1] parm from a C++ small
apl as CGI.  I'm usign Dev-C++ v.4, for your info, under Windows98.

  I basically have an HTML FORM that receives input from the user.  The
HTML calls my C++/CGI with GET method, this way I could grab the parm
list with argv[1].  The problem is that the argv[1] is returning a NULL
pointer, instead of the parm list that appear after the ? following the
.exe CGI.

  Any hints?

  Thanks in adv.

  Jose

[Dev-C++] templates and inheritance

[Astar <As...@tu...>]

Hello Dev-Cpp,

I have some problems with using templates.
  
i have template like:

       template <class T, int optimum>
       class CConteiner {
       .......
       };

and i want to make child from it. something like:

      CScene{.....};
      class CScenes:public CConteiner<CScene*, 4>{
      ........}

its ok, when i compile it, but when i try to link it, i have error.
something like:
unresolved link to CConteiner<CScene*, 4>::CConteiner()

i tried to change code to:

      template <class T>
      class CConteiner {
      public:
             CConteiner(int optimum);
             ....
      };

      template <int optim>
      class CScenes:CConteiner<CScene*>{
      public:
             CScenes();
      .....
      };
      template <int optim>
       CScenes<optim>::CScenes(): CConteiner<CScenes*>( optim ){
      ...
      }

but linked error appeared again.... (compiling - ok)
How i can inherit templates like this?

any ideas?
thanx a lot....


PS. source code is approximite, couse i'm trying another ways (
aggregation for example, but it's bad decision)

[Dev-C++] How to ignore special characters on stdin?

[Christian S. <ca...@kr...>]

hi there,
as I stated before, I write a small console terminal for an application.
up to now, I found great help from this list. so thanks for that!
but now I encountered a new problem.

I am reading my commands from stdin.
but when you press an arrow key or alike, an escape sequence is printed
on the screen, which anoys a lot.

how can I prevent such behaviour, or (better) use these key for a small
command history within my app?

thanks a lot!

[Dev-C++] Two compilation bugs

[<Mys...@cs...>]

I really like DevC++ so here are some bugs I've noticed in the new beta.

"The rebuild-all bug"
"compile" or "compile and run" will run the previous compilations' EXE, and 
not the new code I just typed in. But if I "rebuild all" it compiles the new 
code.

"The occasional not-saving correctly bug"
When saving sometimes it won't compile small changes.
It happens mostly when cutting or pasting a few lines, possibly if you don't 
hit the keyboard between two saves? Because when it happens, if I go to the 
source file(s) and hit space or any key and resave, then it saves correctly..

[Dev-C++] vUpdate broken???

[Reid T. <Rei...@at...>]

It appears that the update from vUpdate 1.616 to 1.617 introduces a
fatal error????
Version 1.616 connects to the server, recognizes that 1.617 is
available, downloads and installs it.
From this point on attempts to update result in the error message:
Error:  server returned code 504
Error:  server temporarily down?????

Hi,

I tried what you told us.
It works :)

There are two shortcuts: CTRL+ALT+. as 'notes on' and CTRL+ALT+ as 'notes off'.
I deleted these shortcuts, after that the ';' character works perfectly.
I know, RTFM :)
Thanks again :)

[Dev-C++] regexec() help needed

[Christian S. <ca...@kr...>]

hi there!

I want to have regexec parse a string by a re that I wrote.
that works fine.

but I want further to have an array resulting, that holds each
parenthesized subexpression found/not found in the string.
I reccon that is done by the 3rd and 4th argument to regexec, but I need
to see some example of how to declare and then use those arguments.

something like: printf("//%s//%s",match[0],match[1]);

google brought me a lot of examples which all ignore those matches..

so please.. =)

Re: [Dev-C++] two-dimensional arrays

[Daniel G. <sp...@ho...>]

Try two nested for loops, like

for (condition relating to [x][])

   // then
   for (condition relating to second dimension [][x])

So you end up with
[0][0] to [0][9] (or whatever) then you come out of the inner for loop. Then 
control goes to the outer loop and then goes back into the second to do 
[1][0] to [1][9]

Of course you couldn't since they belong to the C subset of C++ (that is
they are valid C++).

If you say to them that printf() is not C++ then you are wrong. What you
must say is that C++ provides newer facilities which are superior
alternatives.

No because it is C++. You haven't any mixture of the 2 languages. Personally
I wouldn't mark it as wrong since it is not.

[Dev-C++] two-dimensional arrays

Hello

Could somebody help me to solve the following problem?
I have to swap two two-dimensional arrays. I wouldn't like to do it in
this way:

...
double vec_1[N][M],vec_2[N][M],temp;
int i,j;
...
for(i=0;i<N;i++)
   for(j=0;j<M;j++)
      {
       temp=vec_1[i][j];
       vec_1[i][j]=vec_2[i][j];
       vec_2[i][j]=temp;
      }
...
      

Thanks for advance. Peter.
