[Dev-C++] WxWindows

[RICARDO H. F. <OP...@si...>]

	Does anyone know how do I use WxWindows with DEV-C++ ?
	Which 'def' do I have to use ?
	Does the library that I had compiled in Visual C works with gcc
?
	I have to use DEV-C++ with gcc compiler and wxwindows interface,
I'm kinda lost, if someone have some information that could help me, I
would appreciate.

	Thanx,

 Your program is valid and compiles. There's probably a problem 
with the includes or libs (i.e; are they found?) on your side.

 It'd help if you'd gave us the first few lines of error-messages.

[Miguel M <st...@ya...>]

Hey whats up people. Have another problem again... Im
just starting to learn how to program so this may seam
strange but Im trying to compile a simple little
program. Its so I can get use to iostream.h

---

#include <iostream>
using namespace std;

int main() {
  // Specifying formats with manipulators:
  cout << "a number in decimal: "
       << dec << 15 << endl;
  cout << "in octal: " << oct << 15 << endl;
  cout << "in hex: " << hex << 15 << endl;
  cout << "a floating-point number: "
       << 3.14159 << endl;
  cout << "non-printing char (escape): "
       << char(27) << endl;
}

----
I try to compile this and I get like 400 and something
errors. Its strange. Am I going something wrong.
Thanks in advance. Later

Yes you can not have a reference to a pointer with exception to
templates.

Yes, you probably made some logical error in the definition of
operator<(). Send us its definition.

 I'm in a good mood today, so I wrote you up a short example using 
a functor predicate. I'm sure it can be solved using an overloaded 
operator<() too, that's just now how I'd do it.

#include <iostream>
#include <string>
#include <vector>

using namespace std;

template <typename T>
class on_age
{
public:
    bool operator() (const T& v1, const  T& v2) const
    {
        return v2->age_ > v1->age_;
    }
};


struct t_person
{
    t_person(const string& name, int age) : name_(name), age_(age) 
{ };

    string   name_;
    int      age_;
};


int main(int argc, char *argv[])
{
  vector<t_person*> people;
  vector<t_person*>::const_iterator it;

  people.push_back( new t_person("Gordon", 31) );
  people.push_back( new t_person("Tiny", 1) );
  people.push_back( new t_person("Alice", 16) );
  people.push_back( new t_person("Second", 2) );
  people.push_back( new t_person("Grandpa", 101) );

  sort(people.begin(), people.end(), on_age<t_person*>() );

  for( it = people.begin() ; it != people.end() ; ++it ) 
    cout << (*(it))->name_ << ", " << (*(it))->age_ << endl;

  // yeah, yeah, "leak". Whatever
  return 0;
}

[Dev-C++] STL sort() problem

[Abhijit S. <mu...@gm...>]

Greets.

I'm using a vector of a structure pointer (I use dynamic allocation), like
so:

    vector<PlsLine *> lines;

and PlsLine is a structure:

typedef struct _PlsLine
{
    char    *fn;            // Full filename (c:\foo\bar.mp3)
    char    *filename;      // Filename part only (bar.mp3)
    int     size;           // Filesize
} PlsLine;

I need to sort this, and I call sort() like this:

    sort(lines.begin(), lines.end());

However, sort() uses the comparison operators (< and >), and I can't define
them for pointers... The compiler flags this:

    bool operator <(const PlsLine *&left, const PlsLine *&right)

as an error. It says it should be a class or enumerated type. I tried doing
this:

    bool operator <(const PlsLine &left, const PlsLine &right)

and the compile worked, but it doesn't seem to sort.
Any work-around?

[Dev-C++] brush gets modified

[Carlos d. M. <cg...@wo...>]

I am writing a program which displays a series of bitmaps, placed such
that white is transparent, and it shall be displayed over a red
background.
The bitmap mask is generated by the program in a way specified at the
Forger's win32 programming tutorial, so I select the color bitmap in a
first memory device context (created with createcompatiblebitmap [I omit
the upper case only in the messages, not in the code]) to which I select
the color bitmap, I create a second bitmap with the color bitmap
dimensions and select it in a second memory DC, the bitmap is monochrome
with 1 depth and correct, then I bitblt from second to first with
SRCCOPY, then from first to second with SRCINVERT, then I bitblt from
second to the window, and bitblt from a previous memory device in which
I select the color image (I select it now) to the window, so the image
is set with white as transparent color to the window. And befora all
this I selected a brush.
I have an object with a member which is HBRUSH hbrush, in its
constructor I set it to  red with createsolidbrush(RGB(255, 0, 0));,
then I have a function which is HBRUSH getBrush(){return hbrush} (It is
not inline but I write it this way in the message, so I don't spend
writing the code exactly, but I spend this explanation :)),
so before all that, I write brush = object.getBrush(); (object is a
static variable in WindowProcedure).

So, the image shall be displayed over a red background, and it is true
for the first three (perhaps one, two or four) bitmaps (the full amount
of bitmaps is sixteen, divided in two sets of eight), but after that the
background gets white. It doesn't happen if I substitute in windowproc
brush = object.getBrush(); with brush = createsolidbrush(RGB(255, 0,
0));.

Here is the code of the WM_TIMER: (where all these things happen)

The comments are added in the message.

           {

I don't achieve to see any reason for that behavior, don't find my
error. Perhaps, that use of hbrush in objects is not correct?

Thanks in advance, and sorry if stupid message.

Yes, I suppose many things (other than the error which leads to the
color) can be improved, and I'll do that, now I am just in the beginning
of the experiment, doing things in the right first place, later I'll put
many of these things inside the object and more adequate places.

Relax... I know your pain :).

First of all, try removing everything related to your modem from your
computer (including drivers, sound devices, etc). Some related devices may
be showing up as unclassified ('PCI communications device' under 'Unknown
devices'). To uninstall the drivers, check under 'Add-Remove programs').
Next, go to the 'windows\inf' directory and move all files related to your
device to a different directory as backup (not under 'inf' itself). Then
restart, and the modem should be detected. If it's not, and your modem
drivers come as an executable, run it and it should be installed.

All the best :).

Try pasting the code into a new Windows GUI project. Alternately, link it
with the gdi lib (add '-lgdi32' to the command-line).

I recall having this problem... I don't rememeber exactly how I resolved it.
Try setting up your window and showing it using ShowWindow() or something.
Maybe messages are sent only once the window is created and shown. This
would explain the MessageBox() thingy making it start working.

[Dev-C++] Problem

[Miguel M <st...@ya...>]

Hey all. Whats up. I have a problem when Im trying to
compile a simple window program. I keep on getting the
error message:
 

 C:\Documents and Settings\Miguel\Desktop\Enticing
Software\Demos\DEMO2_3.CPP
[Warning] In function `int WinMain(HINSTANCE__ *,
HINSTANCE__ *, CHAR *, int)':

114 C:\Documents and Settings\Miguel\Desktop\Enticing

 C:\DOCUME~1\MIGUEL~1\LOCALS~1\Temp\ccuabaaa.o
[Warning] In function `WinMain':

 
[Linker error] undefined reference to

I have worked with the compiler options and the
directories but nothing. I tried it with VC++ and it
worked fine. Now Im using version 4.9.5.0. Any reply
would be greatly appreciated. Thanks. Oh and the
source is attached.

[Dev-C++] timers

[Ramana K. <ra...@my...>]

Hi, did anyone even get this message? or did nobody know the solution :(
i sent it a little while ago:
---------------------------------------
Hi, I have a problem concerning timers in windows.
I am using only win32 API, and i use the fuction:

 SetTimer(hwnd,id,len*100,NULL);
//hwnd is the HWND of the window, id is a UINT, len is a UINT

to set a timer that will later send a WM_TIMER message to my WindowProc. In
my WindowProc i have code like this:

 case WM_TIMER:
 {
  myclass->blah();
  return 0;
 }
//myclass is a pointer to an object with a function called blah

and the function blah sets bool thebool to the value false.

in the function that calls SetTimer, i later have the code:

 thebool = true;
 while(thebool)
 {
  MessageBox(hwnd,"WAITING","ERROR",MB_OK); //this gets deleted
 }

when i run the program, the messagebox comes up a number of times until
len*100 milliseconds has passed, then it resumes normal operation.
The problem is, i do not want to have to put up this messagebox. So i delete
the code for it. Once i do this, it seems the WM_TIMER message is never sent
for some reason. even if a put a messagebox in the case WM_TIMER: section,
it is never shown, unless i keep the messagbox in the while loop.
what is the meaning of this?
how am i using the timer wrongly?
thanks in advance
ramana
ps i also tried putting WaitMessage(); in the while loop instead, but it has
no effect.

[Dev-C++] Moden Not working after win 2000 update

[Napoleon A. <nah...@so...>]

Hello,

Let me appologise for bothering this forum with what is a non related =
matter but such is my frustration.=20



I have an Intel celeron 566 PC with an intel 810 chipset. It originally =
had windows 98 se which i have upgraded to 2000. The upgrade report =
indicated the possiblity of the Modem and the network adapters not =
working so I downloaded a windows 2000 compatible driver from PCtel for =
(HSP56 micromodem which is the modem I've got).



I updated the modem driver after installing win 2000 but it hasn't =
worked since. I have repeated the driver installation several time =
without success. I have taken the modem(built in) out , restarted the =
PC. I have put it back in and restared but it still didn't pick it up. =
It's as if win 2000 doesn't see the moden at all.



Has anyone had this problem before and if so what can do to resolve it. =
As a result, I'm unable to connected to the internet with my PC. I have =
to use a friends. Any help welcome please I'm desperate. Please.

Also even if you use printf() inside the for loop, things will go much
faster if you minimize the console (command prompt) window during the
execution. And this because windows will not have to display every
number.

Did you printed the result after every x++ inside the for loop in QB?

Of course it can. Printing in console is slow (the time cost of a
function call, etc).

Theese arguments are not needed.

No accurate results with this method.

Here you have 100000 function calls for printing in the console.

A better program:


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

int main()
{
 clock_t t1, t2;

 long int x;

 t1=clock();

 for (x = 1; x <= 1000000;x++)
     ;
     
 printf("%ld\n", x);

 t2=clock();

 printf("\n\nProcessor time: %lu", (unsigned long)t2-t1);
 printf("\nIn seconds: %f\n\n", (double)(t2-t1)/CLOCKS_PER_SEC);

 system ("PAUSE");

 return 0;
}



The above prints the final value of x only.



Using MINGW GCC 3.1 with optimizations:


gcc temp.c -o temp -ansi -pedantic-errors -Wall
-fexpensive-optimizations -O3 -ffloat-store -mcpu=pentiumpro


C:\c>temp
1000001


Processor time: 0
In seconds: 0.000000

Press any key to continue . . .



Here obviously the compiler performed an optimisation with which he saw
the final result of the loop and avoided the loop completely.


Running the GCC 3.1 without the optimisation switches:


C:\c>gcc temp.c -o temp -ansi -pedantic-errors -Wall

C:\c>temp
1000001


Processor time: 10
In seconds: 0.010000

Press any key to continue . . .



Here it performed the loop and it took it 10 msec (something similar
will happen with Dev-C++ eith optimisations off).


In summary, your time cost was imposed due to 1000000 function calls to
printf().

Re: [Dev-C++] wxWindows

No, I'm using a separately installed MinGW compiler, and as you can see
from the extra Includes/libs, I keep the libraries/includes away from the
compiler directories, since I want to be able to easily switch between
different versions of wxWindows.

Re: [Dev-C++] speed test

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

What should be noted is that your test code doesn't test the speed of the
Dev-Cpp++-generated program - which in fact is the MingGW- or
Cygwin-genrated - but instead measures the time to process a couple of
million bytes of output to standard out.

Do you redicrect the output, or is it scrolling in a text window. What
size is the text window etc.

This kind of programs also notoriosly generates a large percent of system
(kernel) time, giving the OS scheduler some extra concerns about how to
schedule between this and other programs.

Re: [Dev-C++] What is the meaning of 'Clock skew detected'?

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

It usually occurs when you are storing your source files on a remote disk
volume.

The development environment - make - is using the local PC clock to decide
what to do. However, for a number of file-sharing protocols, the
last-change date on the files are set by the computer actually owning the
files, i.e. exporting the file system.

The make program emits the clock skew message if it compiles a file and
notices that the emitted output file got a time stamp "older" than the
source file.

The correct solution is of course to use ntp or similar to keep the clocks
synchronized between file servers and workstation machines.
