dev-cpp-users Mailing List for Dev-C++ (Page 3)

Hello all.

Suppose you are asked to suggest 5 somewhat small
books that will significantly improve C++/software
engineeering literacy in a company whose main product
is a 500,000 line software written in (you guessed
it!) C++. Most of the employees are
otherwise-intelligent Electrical Engg. graduates who,
unfortunately, write HORRENDOUS code ("it doesn't
matter what the variable is named as long as it is
named something", "don't worry about where I place my
function, just use it", dynamically allocated objects
where automatic variables would *perfectly* suffice,
massively redundant coding, zero documentation...).

What would your suggestions be?

VM.

Hi Andreas,
WtsApi32.lib and WtsApi32.h files you can find in Microsoft Platform 
SDK. You can download Platform SDK for free from www.microsoft.com (~384 
MB). Location is 
http://www.microsoft.com/downloads/details.aspx?familyid=EBA0128F-A770-45F1-86F3-7AB010B398A3&displaylang=en
If you don't like to download Platform SDK I can send to you only this 
two files (~30 KB)

Good luck,

Blagoja

Hello,

I use dev-cpp together with QT 4.01.
I created a templated file like explained in
http://translate.google.com/translate?u=https%3A%2F%2F2.zoppoz.workers.dev%3A443%2Fhttp%2Fnicolasj.developpez.com%2Farticles%2Fqt4%2F&langpair=fr%7Cde&hl=de&ie=UTF8

For qt projects a custom makefile must e used.
I tried to put this lines to the [ Project ] section of my template file

UseCustomMakefile=1
CustomMakefile=Makefile.Release

but this does not work. Dev-cpp ignores this parameters.
Is this the wrong section or is it necessary to set the full path to the 
makefile ?

How can i set in the template that the exe is build in the "release" 
sub-directory  of the project

Bye
Andreas

  Thanks Eric...

  Indeed i had "libodbc" and similar, just not "libobjc"

  But i put the file where Alfred said, and linked it as Hind said,
  and it's now working great....

  When i reinstall, i will see if i'm missing the file next time...
  So thanks again guys... Hind, and Alfred, and Eric, much appreciated.

  Cheers,
  Scott.

Hey Scott,

Sent that file as an attachment to your e-mail address.

Hi Alfred, 

 

Hmm i can't seem to find it at all, in my DevC++ install.

I did a search i found 12 files with a "libo*.*   prefix

 

But alas, did not find any matching or looking like libobjc.

in any directories, anywhere  (strange) Anything else i can do?

 

Can someone send me this file?

I will look at doing a Reinstall after that...

 

Thanks again...

Hi Scott, 

 

Try doing a Windows Explorer Search from F:\Programming\Dev-Cpp\ for
libobjc*.*.  It should reside in the lib folder of dev-cpp or in a path
declared in the libraries directory of the project options.  dev-cpp only
searches default paths and paths defined by the user.

 

You may find that it's not in the expected path.  That assumes that the
argument to the linker options is -lobjc, BTW.

Thanks Hind, I found the option you mean..

I click "add library or object" i then chose libglut

And replaced it with just 1 error... (Doh!)

Sorry, I forgot that I can find that info in Win32 help file.
OK, thanks again. :-)

It starts with an identifier. A in this case is a name - somewhere else
that name 'A' is probably mapped to a number. It is possible to have
resources with text names but it is _very_ seldom used because of all
problems with tools etc...

MOVEABLE means that on older platforms (Win16) the memory allocated for
the icon may move around in the computer if Win3.1 needs to compact
available memory.

LOADONCALL means that all info in the resource file must not be loaded at
the same time. It is enough for the OS to load the icon from the exe file
when it is needed.

DISCARDABLE means that if the computer have little memory, the memory
allocated for the icon may be reclaimed. You may either run the
application without an icon if out of resources, or it may be loaded again
later.

Any ressource used in a program need to be identified, so useally we use 
numbers to be sure that every ressource has a single identifier. I never 
used letters but its have the same role.

Concerning the "MOVEABLE LOADONCALL", this attributes are ignored because 
they concern 16-bit Windows, for the meaning here u are, but as I told u, 
you can find this information in the win32 help (I just copy/paste them)

LOADONCALL : the resource is loaded when called
MOVEABLE : the resource can be moved if necessary in order to compact 
memory.

Concerning the "PURE", I must confess that I don't know, I never use it and 
search to understand it but this attribute is ignored too :)

Have good time :)

It work, thanks for help.

I have another question...can you explain syntax of line in 
test_private.rc file?
A ICON MOVEABLE PURE LOADONCALL DISCARDABLE "test.ico"

Why it start with character "A" and in your example is number "100" ?
100 ICON DISCARDABLE "test.ico"

What is meaning of "MOVEABLE PURE LOADONCALL" ?

Thanks again,

Blagoja

In the ressource file :
     100 ICON DISCARDABLE "test.ico"

And be sure that the icon file is in the same directory than the source file 
or change the path, for example "res//test.ico" if the icon is in the res 
directory.

In the header file or the source file:
    #define ID_ICON        100

And in the source file :
    wincl.hIcon = LoadIcon (hThisInstance, MAKEINTRESOURCE(ID_ICON));

If you need more information about the syntax or the use of the win32 
functions, use the win32 help, try for example this link to download it :
dimcom.uqac.ca/~ecoete/ftp/mmedia/MSHelp/WIN32.HLP

Hi,
I write simple aplication from templates and I want to insert icon 
(my.ico) into exe file like resource, and after that when I compile and 
run application see that icon in the list when click Alt+Tab and in the 
left side in the app titlebar.

In test_private.rc file is only this line:

A ICON MOVEABLE PURE LOADONCALL DISCARDABLE "test.ico"

Can somebody explain me syntax of this line or tell me URL on the net 
where can I find explanation of .rc file format, please?

When I compile app only see test.exe with icon (test.ico) in the Windows 
Explorer and when I start exe default Windows icon IDI_APPLICATION is in 
Alt+Tab list.

I know that I must change this lines in the main.c file:
     wincl.hIcon = LoadIcon(NULL, IDI_APPLICATION);
     wincl.hIconSm = LoadIcon(NULL, IDI_APPLICATION);
but I don't know how to use LoadIcon function. MSDN for LoadIcon have 
little info and don't help me.

Can somebody write simple example for line in .rc file (how to insert 
"my.ico" to exe) and example line in main.c file (wincl.hIcon = 
LoadIcon(???, ???);) please?

Thanks,

Blagoja

Did you add the library in the linker (see project options)?
Do it and u will fix the problem.

   I'm getting 18 errors like the following with DevC++

   I use DevC/C++ without problem usually, but i get
   these errors, as part of a 3D SDK....

   Is it a Opensource OGL library issue, can it be fixed?

    [Linker error] undefined reference to `glClearColor@16'  [Linker

    reference to `glColor3f@12'

Hi,
a have problems building log4cxx.
I'm using
Dev-C++ 4.9.9.2,
apache ant 1.6.5

I think with the STL is something wrong for Windows,
nevertheless I detected redefinitions in a ant-generated
header private.h that leed to compiler warnings only for gcc.

Can anybody help with log4cxx or suggest another logging framework?

Thanks, Wolf Peuker

Hi Hind,
 
I'm working on an imaging application that uses structure arrays of sizes of 22K elements to well over 4M depending on image size.  My problem usually occurs when mapping an array of floating point elements to array indicies.
 
Usually, for algorithmic reasons, an array element is in the form vect[i]={x,y,z}, double precision.  However for screen plotting I need an array in the form vect[x][y] = z.  It is in this conversion that most of my access violations or segment errors occur.
 
If I have an array of 3-vectors (x,y,z) and then preform a 3d transform (i.e. rotation on multiple axes), occasionally the resultant x and y coordinates will exceed the declared array size.  My correction to this is to scan the resultant array of 3-vectors for maximum transformed x and y values, then generate a new array that has those maximum sizes.  A further benefit is that it condenses a 3-vector array element of 24 bytes (3 doubles) to an x and y indexed array element of 8 bytes (1 double).  Then I can delete[] the original 3-vector array.

Bad programming - most probably either references to a NULL pointer,
access to an uninitialized pointer or access outside the bounds of an
array.

In this case I think you are sending bad parameters to a Win32 API.
