RE: [Dev-C++] stl and windows apps

[James G. <Jam...@Cl...>]

I assume that you have included the line 'including namespace std;' or
'including std::list;' in there?

Regards,

James.

Subject: [Dev-C++] stl and windows apps


posted this on the forum but hoping that more people will read it here...

i've had some real problems using the stl in programs compiled for windows 
(i.e. no console)... vector::push_back, the string constructor and the list 
constructor will all cause runtime errors...

does anyone know how to sort this out, or am i going to have to write my own

stl?

here's an example of some code that will die

#include <list>
#include "windows.h"

int WINAPI WinMain(HINSTANCE, HINSTANCE, LPSTR, int)
{
list<int> li;
return 0;
}

thanks in advance,

  richard

i think the statement is 'using namespace std', but this stl seems to be a 
bit confused about where various things should go, and you can have things 
in the std namespace whether or not you 'using' it. anyway, that should 
cause a compiler error, and the problem here was a runtime error :O(

thanks for the suggestion,

Opps! That will teach me to try and remember this from a year ago rather
than looking it up!

What is the runtime error?

I haven't tried this is a windows program but it's okay in console mode?

Regards,

James.

the runtime error is the usual Windows 
take-it-back-to-whoever-sold-it-to-you jobby... not fantastically specific 
:O(

>I haven't tried this is a windows program but it's okay in console mode?

yeah i've had hardly any trouble with the stl stuff in console mode - it's 
only when its built for windows that problems start appearing. it's 
especially annoying because i've been using the console to develop modules 
and make sure they're working, and then when i move them into a proper 
windows app, they blow up without much hint of what's wrong.

i've tried using the debugger on it (gdb with insight frontend) and it goes 
in to the std::list constructor before dying, so i take it there's a problem 
with the stl, or some compiler option i'm setting/not setting which is 
needed.

hmmm... i tried changing it in my code but still got the same error (i think 
it gets the same windows.h regardless of the include method) but then i 
looked more closely at your code and realised that you had your #include 
<windows.h> *before* your #include <list> where i had it after. apparantly, 
this makes all the difference :O)

many thanks,

   richard

Good observation. I didn't know that.

As a standard I always include the windows headers first and the C/C++
headers after. I never thought the order was important.

Now I learnt something new. Thanks

I know what the problem is.

should be 

#include <windows.h>

I tried this and works. When I tried your code it showed the annoying
error message.

#include <windows.h>

#include <list>

int WINAPI WinMain(HINSTANCE, HINSTANCE, LPSTR, int)
{


list<int> li;

MessageBox(0, "list created", "Test", MB_OK);
return 0;
}

Re: [Dev-C++] stl and windows apps

[Andre` N. C. <ca...@op...>]

I have a quick question how do you know when to use "" or <> when typing
includes? I.E.
#include "resource.h"

Re: [Dev-C++] stl and windows apps

[guus <gzu...@de...>]

You should use the " " if the include files aren't in the same directory as
the compilers directory.(Set the path to....)
You must use the <> if the include files are in the compilers directory.

Re: [Dev-C++] stl and windows apps

[Michael P. <mdp...@ya...>]

I believe that the <> will search for the file in the
include directories as specified in Dev_C++.

The "" will use the systems (windows) path resolution.

Anyone else have a better definition?

Re: [Dev-C++] stl and windows apps

[<jos...@ya...>]

I found these definitions in my archive
**********************************************************************

There are two slightly different formats for file inclusion: one using
"" and the other using <> 

1)	#include <myfile.h> says to look in established system directories
for the file to include. How these system directories are established
and where they are located is system dependent; that is, it depends
upon the system on which you are working. 

2)	#include "myfile.h" says to look in your current directory for the
file. If not found there, the preprocessor will look in the system
directory. This is not necessarily true for all
compilers/preprocessors. 

*********************************************************************
This is from WinAPI

The #include directive causes resource compiler to process the file
specified in the filename parameter. This file should be a header file
that defines the constants used in the resource-definition file. Use
the statement 

#ifndef RC_INVOKED
 

in your header file to surround statements that can be compiled by a C
compiler but not RC. This way, you can use the same include files in
your .C and .RC files.

Syntax

#include filename

Parameter

filename

Specifies the name of the file to be included. If the file is in the
current directory, the string must be enclosed in double quotation
marks; if the file is in the directory specified by the INCLUDE
environment variable, the string must be enclosed in less-than and
greater-than characters (<>). You must give a full path enclosed in
double quotation marks (") if the file is not in the current directory
or in the directory specified by the INCLUDE environment variable.

 

Example

This example processes the header files WINDOWS.H and HEADERS\MYDEFS.H
while compiling the resource-definition file:

#include <windows.h>
#include "headers\mydefs.h"

**********************************************************************

As a rule of thumb I can say

1) If you're including headers from the compiler/stl/etc use <>

2) If you're including your own header files use ""

Hope this clarifies

Chemanuel
