Re: [Dev-C++] Application Icon

[Per W. <pw...@ia...>]

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.

Re: [Dev-C++] Application Icon

[Hind F. <the...@ho...>]

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

RE: [Dev-C++] Application Icon

[Hind F. <the...@ho...>]

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

[Dev-C++] Application Icon

[Blagoja G. <bla...@gm...>]

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

Re: [Dev-C++] Unhandled exception

[Alfred P. R. <al...@ya...>]

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.

Re: [Dev-C++] Unhandled exception

[Per W. <pw...@ia...>]

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.

Re: [Dev-C++] Exception Handling

[Wolf P. <pe...@re...>]

Yes, but you should catch the base exception class by (const-) reference.
for example:

class GeneralX {
  public:
  // properties ...
  virtual bool IsSpecial() const { return false; } // 
Standard-Implementation
};

class SpecificX: public GeneralX {
  public:
  // further properties ...
  SpecificX(): m_kind( 815 ) {}
  virtual bool IsSpecial() const { return m_kind > 0; } // overrides 
Standard-Implementation using new Member
  int m_kind;
};

void may_emit(bool x_trigger) {
  // do something...
  if( x_trigger )  {
    throw SpecificX();
  }
   // do something else...
}

bool test_byref( bool x_trigger) {
  bool bSpecificCaught = false;
  try {
    may_emit(x_trigger);
  }
  catch( const GeneralX& e ) { // catch by reference
     // do something with e...
     // if you check against SpecialX you would succeed:
     bSpecificCaught = e.IsSpecial();
  }
  return bSpecificCaught;
}

bool test_byvalue(bool x_trigger) {
  bool bSpecificCaught = false;
  try {
     may_emit(x_trigger);
  }
  catch( GeneralX e ) { // catch by value
     // do something with e...
     // if you check against SpecialX you would succeed:
     bSpecificCaught = e.IsSpecial();
  }
  return bSpecificCaught;
}

bool test_all_passed() {
  bool by_ref_result = test_byref(true);
  bool by_value_result = test_byvalue(true);
  return
    (by_ref_result == true) &&
    (by_value_result == false);
}

This compiles with devcpp test_all_passed() returns true for me.

[Dev-C++] Class browser and method's throwable exceptions declarations

[Gaetano S. <gae...@gm...>]

Hello,
the class browser seems to be confused when encounter throwable
exceptions declarations on methods prototypes. Take as example the
following code piece:

[myexception.h]
#include <string>
#include <stdexcept>
using std::string;
using std::runtime_error;

namespace my
{
  class MyException : public runtime_error
  {
    public:
      MyException(const string& msg);
  };
}

[myexception.cpp]
#include "myexception.h"
using my::MyException;

MyException::MyException(const string& msg)
:runtime_error(msg)
{
}

[myclass.h]
namespace my
{
  class MyClass
  {
    public:
      MyClass();
      ~MyClass();
      void my_method(int something) const throw(MyException);
  };
}

[myclass.cpp]
#include "myclass.h"
using my::MyException;
using my::MyClass;

MyClass::MyClass()
{
}

MyClass::~MyClass()
{
}

void
MyClass::my_method(int something) const throw(MyException)
{
  int remind_me;

  if (something !=3D 0)
    throw MyException("Hey! You must pass 0 as argument!");
}

Ok, in the class browser i see:

+MyException
+MyClass
|  |- ~MyClass()
|  |- MyClass()
|
|- remind_me : int

1 - Below the MyClass node "my_method" does not appear;
2 - The "remind_me" variable declared into "my_method" appear as a global o=
ne;
3 - This happen for all methods with a throwable exception declaration;
4 - The project compile and link as expected, without warnings or errors.

Have someone any ideas about how to fix it?

Thank you,

[Dev-C++] Exception Handling

[Noorez K. <lor...@ho...>]

For my program, I have a main exception class to handle general exceptions 
and all the other exceptions are derived from that one. In the catch block, 
can i catch an error of type "general exception" for all the exceptions 
derived from that class?

[Dev-C++] PostgreSQL and Dev-Cpp Dev-C++ on Windows example

[Reid T. <jre...@ea...>]

I thought it might be of interest to post steps to using PostgreSQL on 
Windows with the Dev-Cpp/MINGW IDE/compiler.  This example is C, but the 
steps for configuring the IDE/Project to use the PostgreSQL libs/headers 
should be the same or very similar for C++/ecpg.

Install PostgreSQL for Windows using the windows installer ( for those 
who haven't used the PostgreSQL windows installer, it's a quick and easy 
process ).

Start Dev-C++.
File->New->Project.
Select Console Application.
Select C project.
Give the project a pertinent name ( myPgsqlTest ).
Click OK.
Create a new dir to contain the Project ( give it a pertinent name).
Save the initial project.
Select Project->Project Options.
  Select the Parameters Tab.
  Click the Add Library or Object button.
    Traverse to your PostgreSQL installation's lib directory - mine is
    ../../../PostgreSQL/8.0/lib/ and select libpq.a.
    In my case, the linker window now contains 
../../../PostgreSQL/8.0/lib/libpq.a.
  Select the Directories Tab.
    Select the Include Directories sub-tab.
      Traverse to and select your PostgreSQL installation's include 
directory - mine is
      D:\PostgreSQL\8.0\include.
      Click on Add ( your Include directories window should now list 
this path.
Click on OK to close the Project Options Dialog

Insure that the db 'test' exists in your PostgreSQL instance, or change 
'test' in the conninfo to your test db when you populate the other 
appropriate values for your connection. 

Replace the Dev-C++ template created main.c

#include <stdio.h>
#include <stdlib.h>

int main(int argc, char *argv[])
{
 
  system("PAUSE");   
  return 0;
}

with ( this is based on the libpq example from www.postgresql.org/docs )

#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include "libpq-fe.h"
