Hi, Danny

If your program is a console application, what I'll say should work, if 
instead your  dealing with Windows applications, I can't help you. I'll 
also assume that Windows is your OS.

Your question is: given source files, how do I build the binary file?.

There are two ways I can think of: one uses Dev-C++ (so it is a GUI method) 
and the other is the classic CLI method resorting to makefiles.

-Using Dev-C++:
1- use Explorer to make a new folder (say c:\test) and move (or copy)  the 
source files of your program (dynarray.h, dynarray.cpp and your main which 
I'll name test.cpp) to it;

2- start Dev-C++, from the "File" menu select new project, then select 
"console application" and give a name to your project (the obvious choice 
would be "test", so that "test.dev" would be created, but then Dev-C++ will 
not allow you to add the file "test.cpp" to the project, so I suggest you 
use "test_prj"), also save your project file to "c:\test" (so that 
everything is stored in one folder);

3- close the "Untitled1" window, and remove the "Untitled1" file from the 
project (by left clicking on "Untitled1" in the project manager window and 
then choosing "remove from project");

4- left click on "test_prj" in the project manager window and choose "add 
to project", then select the three source files you have in the directory 
"c:\test";

5- from the "Execute" menu, select "compile", this will build the binary 
file named "test_prj.exe" (if your code is error free! (-; ), you can now 
run it from inside Dev-C++ in the usual way (i.e selecting "run" from the 
"Execute" menu).

-Using a makefile:
this approach is a bit longer to describe and probably you are not 
interested,  so I'll say nothing about it, I just mentioned it so that one 
knows the method exists (actually makefiles are nice tools when your OS has 
no GUI). If instead you are interested let me know and I'll try to explain 
an easy way to put up a simple makefile and to use it to build/update your 
binary file.

I hope the above helps.

Hi Stein.
I have an idea how to make a window "unresizable".  Either just don't define
a resize-function (I guess, this would be the wrong way) or instead of using
the resize-parameters you always use the same values for defining the
"resized" viewport.  If this doesn't work - I wouldn't have another idea ...

Which method are you using for displaying the double? Is it printf or cout?

For cout then you need to change the value of precision it used, as you have
noticed it defaults to 6.

The ios member function precision(15); should do the trick. i.e.

cout.precision(15);

I think I got that right. There are other ways of doing the same, but I'll
let you look them up. I/O manipulators and flags (ios class).

With printf then you have to modify the format specifiers a little i.e.

printf("My double value is: %1.15f\n", MyDouble);

I don't use printf often so it's up to you to make sure it is right. The
first number after the % specifies the minimum number of digits displayed,
the number after the decimal point is the precision and then the f says you
want to display a floating point value.

I recommend you get a good reference book to allow you to look up stuff like
this, which is what I did. I suppose I had the advantage of knowing where to
look :)

Jason.

When you refer to CString are you talking about a class of some kind or are
you mixing up the C++ class String with a c "style" string?

A c style string is in fact a null terminated string, and when you write
"Hello World!" (note no need for \0) you are just declaring a null
terminated string.

If you are useing the C++ String class then to use it as a C string you have
to use it's member function c_str(); which returns a pointer to a temporary
c style string. Note that you shouldn't try to modify the string through
this function.

The way that most compilers work is that they will compile each individual
cpp file into an object file (.o). All these object files are then passed
through a linker program which connects then together, mainly making the
function calls in one cpp file point to the relevant function in another
cpp. The linker will output the executable code (.exe). You shouldn't ever
need to include a .cpp file into any other cpp file or header, you only
include the header (.h) file if you happen to need a function from one of
the other cpp's (or libraries). In fact it is considered bad practice to
include a cpp into another.

This is only a quick explanation of the process. Before IDE's you would have
edited all the code in a text editor of some kind and then typed in the
commands like gcc MyCPP.cpp, link MyCPP.o etc... (that may be wrong)

To produce a program in Dev-C++ at the moment you need to put all the CPP
files in to a project, making sure that if any one cpp uses a function from
another to #include the header of that cpp at the top. Then click on compile
and the rest of the work is done for you. If it's successful then you will
be given the option of executing it, otherwise you will be presented with a
list of errors, that you can double click on to take you to the relevant
section (most of the time). If you are editing the headers aswell then it is
safe to add them to the project also, as one of the faults with Dev-CPP at
the moment is that it won't let you edit a file that isn't part of the
project without closing the project.

Remember that most linker errors occur because the .o or .a (library) file
wasn't given to the linker program. Undefined reference or first occurance
type errors are usualy because you either failed to declare a function
prototype or variable, didn't include the relevant header, or you mistyped a
name somewhere.

Hope this helps.

Regards, Jason.

add cout.precision(15) prior to cout'ing it.
ie.
    double n;
    n = 0.2343434343434;
    cout.precision(15);
    cout << n;
--tim

Hi List,

If I print a double variable I get
only 6 decimals. How can I get all
decimal (15) ? 

Thanks
Horst

I wouldn't try and count the amount of memory available as you would get a
missleading figure. Memory addresses don't directly map to the real
addresses used by the system and Windows makes up for lack of physical RAM
by using Virtual Memory (a swap file). Also trying to access memory not
assigned to you will cause access violations to occur. After a quick look in
the Win32API Reference I found the function GlobalMemoryStatus(); which can
be used to obtain various memory usage details, including the amount of
physical RAM in the system.

A quick summary:

#include <windows.h>
#include <iostream>
...
MEMORYSTATUS meminfo;
meminfo.dwLength = sizeof(MEMORYSTATUS);
GlobalMemoryStatus(&meminfo);
cout << "Amount of Physical RAM = " << meminfo.dwTotalPhys << endl;
...

This is an untested segment, but should work OK. Check out the Win32API
Reference for more information.

Jason.

Include them in a project, that's all. And #include "file.h" in
file.cpp, and
#include "file.h" 
#include "file.cpp" in your main.cpp.
But if that doesn't work (I think you ask because that doesn't work, but
I say
it, so if not, you know now), I imagine you would must write all the
code in
the same file...
Well, but I am a so unexperienced about programming, perhaps there would
be
other solutions... Perhaps writing a makefile? (I have no idea about
makefiles)... Or perhaps your copy of the program is a wrong one
(perhaps it
got downloaded badly) and you'll need download it again. (?)

Hi, chromatonus 712

Mr. Hardman gave you the hints you asked for and his code is close to your 
approach, instead what I'm sending you relies on pointers though still 
using your idea of an array to store elements. I did not use the "conio" 
library but only standard I/O operations.

You will not find too many comments because the code is fairly simple, I 
also have the stack not deal with singular events (such as pushing on a 
full stack or popping from an empty one), because I can't think of any 
approach that is different from terminating execution (too abrupt) or 
throwing an exception (not sure how to do that yet); instead I let the 
client check if these events are about to occur.

Probably you will find my code too simple for your needs, but I hope you 
will appreciate it.

Hi List,


I want to sent an UDP Datagram via TCP...

The send and recive function works properly in a console app...

Now i want to make a GUI for that...



The problem is that the editfield in my application is a cstring (m_Edit1),
but my app needs a nullterminated string...

If I convert the CString to a nullterminated string I get nothing ...

If I write strcpy(szSendString, "hjsdfhs\0"); it works ....




I have many things tryed but nothing work...


Did you have an Idea ???

What can I do ?




Kind regrads


Christian

Hola,
I am trying to find out how to properly compile a program when there are
user-written classes involved.  I have 3 files- a header file (dynarray.h),
an implementation file (dynarray.cpp), and my main program.  Using Dev C++,
what is the proper method and order to correctly compile?  This is my first
program where I have had to implement a class, and I can't find information
on how to use Dev C++ to do this.  Thanks!

Danny
