Dev-C++ proyect. I have de .lib and .dll. I put the .lib in the linker

a dll in Dev-C++?

Re: [Dev-C++] File Size

[Lukas 'C. M. <gry...@gm...>]

Note - not sure if it showed up properly, but there is a final } at
the end of the pasted code - for some reason Gmail's tossed it in as
part of the quoted text.

Re: [Dev-C++] File Size

[Lukas 'C. M. <gry...@gm...>]

Hello, Jarren!

Code follows below.  Hope it helps/is useful.  Just drop it into the
main file of a new console app and all should go well.

Please tell me if I've overlooked anything or you're curious about somethin=
g.

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

int main(int argc, char *argv[])

  printf("File name: ");
  char fname[80];
  fgets(fname,sizeof(fname),stdin); // grab file name from user
  fname[strlen(fname) - 1] =3D 0;
  // put a null character at the last place of the string to ensure
that display works properly
  // (to find out why, comment that line out and recompile)
  FILE *fp =3D fopen(fname,"r"); // Open the file as an ascii read-only fil=
e
  if (!fp) return 0; // File doesn't exist/can't be accessed/etc. =20
  char first[5];
  memset(first,0,sizeof(first)); // Ensure that the string will be blank
  fread(first,sizeof(first)-1,sizeof(char),fp); // Read three
characters in from the file
  first[strlen(first)-1] =3D 0; // as like last time (9th line)
  printf("First %d characters of file: %s\n",sizeof(first)-2,first);
  fseek(fp,0,SEEK_END); // Jumps to end of file
  unsigned long int fsize =3D ftell(fp); // Returns position in file
  printf("Size of file: %ld\n", fsize);
  fseek(fp,-2,SEEK_END);
  // Jumps back two from current position in file.  Could also use SEEK_CUR
  // as we're at the end
  // of the file, but this works because we've jumped to the end.
  char last[4];

Ok, what I need to do is open up a file and get the exact number of
bytes in the file, including the first three and the last two
characters, all stored in seperate variables. Example:

//start file.txt
This is a simple text file
//end file.txt

I want to be able to get this:

[Dev-C++] graphics library for windows

[Andrei R. T. <and...@gm...>]

hello list,

I need a graphic library to make a screensaver for windows. Basically, i 
need some functions not available in Windows GDI, as semi-transparent 
shapes and alternative ways of filling a shape (inverting the colors in 
the screen, this kind of thing). It needs to be compatible with Dev-C++. 
I found Anti-Grain Geometry and Libart, with Google, but I would like to 
ask if you know some library that can be useful for me.

thank you,

[Dev-C++] File Handling

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

I'm having some problems with my file handling. The problem is very strange. 
The functions that I attached are all called from the Window Procedure. Here 
is a quick explanation. If I call the SaveAsText() function first, and use 
the SaveText() method, everything saves to the text file fine, when I look 
with notepad. But if I use the OpenText() or OpenTextDrop() function to open 
a text file, then try to use the SaveText() function, nothing goes to the 
text file at all. Can someone help me?

Re: [Dev-C++] Accessing Project Data

[PIBCharon <PIB...@co...>]

hi

just include the header like every other header in one of your project-files :
#include "myproject_private.h"

inside this file there are 3 "defines", like this :
#define VER_MAJOR		0
#define VER_MINOR		1
#define VER_RELEASE	1

well thats all you need! do whatever you like with this version information.
for example print it to the console :
printf( "version of my project is : %i.%i.%i\n", VER_MAJOR, VER_MINOR, VER_RELEASE );

hope this helps.
if not please elaborate your specific problem a little bit more.

greets
Markus

Huh...  Oh, and if you actually want to see your code, you should
include stdlib, and put before the very end "system("pause");" if you
don't want the window to blink in and out of existance faster than you
can read it, unless you're executing it from a command prompt window,
which I doubt.

Anyway, WM_SETSEL is obviously wrong.
WPARAM is start, end LPARAM is end.

WM_REPLACESEL: WPARAM: Can undo, LPARAM text.

Re: [Dev-C++] Accessing Project Data

[PIBCharon <PIB...@co...>]

hi

have a look into your projects directory, there should be a header file with the version info.
its name is "projectname"_private.h .
so if your projects name is "mytest" for example the file would be called "mytest_private.h" .
just be sure not to alter its content, dev-cpp itself alters it with every compile!

greets
Markus

Hi,
you can ask some UNIX/Linux programmers about this, *curses is 
originally UNIX console manipulation library used long before Borland 
came with conio. You can also read manual entries for functions with 
'curs_' prefix at http://www.rt.com/man/indc.html

Happy coding,

[Dev-C++] pdcurses ?

[Big P. <big...@gm...>]

Hi,

is anybody familiar with pdcurses? or curses at all...
I've decided to go back to character mode and not hessle with win32
and other unnecessary (for me) things.
the dev-cpp port of conio misses the window function, so I've dropped
it too, and came up with pdcurses.
it knows many things, lacks only a few, but... is it really good for
working in a dos box? I don't need much portability and like things
which curses were originally designed for... but need some speed of
complex screen handling (editor/emulator purposes)...
opinions?
I can get along with the dev-cpp conio pack as well, but pdcurses
offers me so much more...
TIA,

tom

ps. I'm already convinced not to go win32, tried but didn't make any
good, that is no question... turbovision is way too complicated for my
projects, partly because never used it, and don't can't spend the time

[Dev-C++] Simple window in Dev C++

[Infinity <inf...@ne...>]

 I tried to make a simple window using this code

#include <windows.h>

// Prototype of a function with Windows procedurs

LRESULT CALLBACK WindowProcedure(HWND,UINT,WPARAM,LPARAM);

// Window class name

static char gszClassName[]=3d"MyClass";

// main()

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
LPSTR lpCmdLine, int nCmdShow)
{
      WNDCLASSEX WndClass;
      HWND hwnd;
      MSG Msg;

// Registration of a window class

WndClass.cbSize=3dsizeof (WNDCLASSEX);
WndClass.style=3dNULL;
WndClass.lpfnWndProc=3dWindowProcedure;
WndClass.cbClsExtra=3d0;
WndClass.cbWndExtra=3d0;
WndClass.hInstance=3dhInstance;
WndClass.hIcon=3dLoadIcon(NULL, IDI_APPLICATION);
WndClass.hCursor=3dLoadCursor(NULL, IDC_ARROW);
WndClass.hbrBackground=3d(HBRUSH)(COLOR_WINDOW);
WndClass.lpszMenuName=3dNULL;
WndClass.lpszClassName=3dgszClassName;
WndClass.hIconSm=3dLoadIcon(NULL, IDI_APPLICATION);

// Class registration check

if (!RegisterClassEx(&WndClass))
{
MassageBox(0,"Registration failed","Error", MB_ICONSTOP|MB_OK);
}

// Creating a window

hwnd=3dCreateWindowEx(WS_EX_STATICEDGE,
                    gszClassName,
                    "Window",
                    WS_OVERLAPPEDWINDOW,
                    CW_USEDEFAULT, CW_USEDEFAULT,
                    500, 400,
                    NULL, NULL,
                    hInstance,
                    NULL);

// Window creation check

if (hwnd=3d=3dNULL)
{
MessageBox (0, "Window creation failed","Error", MB_ICONSTOP|MB_OK);
}

// Showing a window

ShowWindow(hwnd, nCmdShow);
UpdateWindow(hwnd);

// message loop

while (GetMessage(&Msg, NULL, 0, 0))
{
      TranslateMessage(&Msg);
      DispatchMessage(&Msg);
}


UnregisterClass("MyClass",hInstance);
return Msg.wParam;
}// END

// Function with Windows procedurs

LRESULT CALLBACK WindowProcedure (HWND hwnd, UINT Message, WPARAM wParam, LPARAM lParam)
{
        switch (Message) {
               case WM_CLOSE:
                    DestroyWindow(hwnd);
                    break;
               case WM_DESTROY:
                    PostQuitMessage(0);
                    break;
               default:
                       return DefWindowProc(hwnd, Message, wParam, lParam);
                       }
}


And I got the following error:

In function `int WinMain(HINSTANCE__*, HINSTANCE__*, CHAR*, int)':
23 [Warning] converting to non-pointer type `UINT' from NULL
39 `MassageBox' undeclared (first use this function)
(Each undeclared identifier is reported only once for each function it appears in.)

[Dev-C++] Shortcut issue

[Infinity <inf...@ne...>]

I have a bit of problem. I had shortcut to compile and run (F9). After I installed a newer version
of Dev the shortcut was no longer set. I set it manually in tools->set shortcuts and it worked. When
I closed and reopened Dev, shortcut was no longer set so I have to do it again every time I reopen
Dev.
What should I do?
