[Dev-C++] Strange Icons

[Ameer K. <sm...@vs...>]

Hi Friends,
Sorry for an Out of topic  enquiry.
The icons on my desktop is behaving strangely.
When the mouse pointer is brought near  any of the icons on the desktop, =
the icon is skipping  away from the pointer.We can move the icon to any =
part of the desktop by following the same with  the mouse pointer.
Is this due to any virus. I have scanned using Norton Antivirus updated =
one week ago.
No problem in opening any of the programmes and I feel the system a bit =
slow.
The strange behaviour is on the  desktop only
Can anybody help me in this case
With regards
Ameer khan

[Flavio de S. <fla...@se...>]

I did it, but I had to do one more thing: change the main() function to the=

following.

int STDCALL
WinMain (HINSTANCE hInst, HINSTANCE hPrev, LPSTR lpCmd, int nShow)

Then it worked well.

Tks everybody that helped me.

Re: [Dev-C++] cout vs cprintf

[Jason H. <jas...@bt...>]

There are advantages and disadvantages to both. printf() is fast =
flexible and usable in c. It has the advantage that the library for =
<stdio.h> is smaller than the equivalent C++ <iostream> so in theory you =
could make smaller apps with it.

However in C++ you can create objects that have stream operators =
associated with them, which allows for a cleaner interfaces most of the =
time. Which makes it easier to output loads of data in an object, i.e =
cout << MyObject; as opposed to printf("Var A: %d, Var B: %s, etc...", =
MyObject.A, MyObject.B, etc...);

In general printf has more in common with other languages such as =
Pascal, and therefore the structured approach. In cout you don't need to =
remember any %letter combinations, as the compiler handles it all for =
you. You can use whatever suits your needs.

In the end the output is directed at STDOUT (or something similar) for =
both.

As for cprintf, does it take the same form as standard printf? It may be =
a dedicated version for a specific implementation, or it only works with =
certain values. I know that standard C does supply a few other printf =
functions i.e. vprintf (I think), but I've never really looked into =
them.

Jason.

Re: [Dev-C++] cout vs cprintf

[David N. <dne...@mi...>]

printf() is a powerful function and allows you to output variables in =
(nonstandard) ways.  Dumping the hex value of a pointer, hex values of =
ints, longs, etc., all without requiring casts.  Lot's of rope to hang =
yourself with.

Re: [Dev-C++] cout vs cprintf

[Jason S. <mys...@op...>]

    Not exactly where it comes from (conio.h tho, no?  I know printf is C, so cprintf is probably just a nice little cousin of it) but do know if you used it on the ap exam it would be pretty icky. :)

    Printf is a little bit more flexible from what I've seen, though.   For instance,

cout<<"I will love you for "<<years<<" years and forever after that!";

can be replaced with

printf("I will love you for %d years and forever after that!",years);

I really don't know more than that, but I'm sure it can probably do other neat things as well.  Whether or not it's better or worse than cout, faster or slower, yadda or not...dunno. ;)

[Dev-C++] Dev-c++ and common controls

[ken b. <kbo...@ea...>]

Has anyone out there actually compiled/linked/run a win32 program using =
"common controls"? This sounds like a dumb question but I just can't get =
a program using "InitCommonControlsEx" to  link. Another computer on my =
network with Dev-c++ does the same thing. The linker spits out =
"undefined reference to InitCommonControlsEx@4" I look at the compiler =
log and see that the linker is using libcomctl32.a (I added that just to =
 make sure that library was being used) still fails.
Anybody know what this newbie is doing  wrong?

thanks,

Ken Bouchard

Re: [Dev-C++] usinng common controls

[Jason H. <jas...@bt...>]

Dev-C++ (MinGW) uses libraries like used in Linux (AFAIK) so they all =
end in .a

They follow the form lib"name".a so you would want: libcomctl32.a which =
you will find in the Dev-C++ or MinGW lib directory.

Re: [Dev-C++] Using Graphics Libraries in Dev C++

[Jason H. <jas...@bt...>]

There is a port of the Borland Graphics Interface that can be used with
MinGW (the standard Dev-C++ compiler). Look at
http://www.cs.colorado.edu/~main/bgi/doc/bgi.html Remember to follow the
instructions to get it all to compile properly. I have had it working with a
little trial and error involving linking in the right libraries. For some
reason using the -l???? command for compiler options never seems to work
right for me, so i just link in the library using the additional libraries
options.

Learning  the windows GDI (Graphics Device Interface) isn't too difficult
either, it depends upon what you need to do in the end.

[Dev-C++] Print numbers n digits wide of number system m. (SOLVED)

[Dario P. <do...@ho...>]

I have to say Mr. Nebinger, you really are skeptic.
Like i said before, this is not homework. It can't possibly be homework
because i don't take any programming classes. I learn on my own. And, on
top of that, i never asked for any code, i merely asked for advice.

I found this problem on the internet, while i was looking for
application information for the University of Helsinki. Here's the link,
knock yourself out: http://www.joensuu.fi/tkt/teh_eng.htm

I'm happy to say that, given all of the advice i got, i was able to
solve the problem.

This is the important part of the code i wrote:

/* Where m > 1 */
for(i = (n-1); 1;)
{
	/* Find the first nonzero array index */
	for(j = 0; nsys[j] == 0 && j < (n-1); j++)
		;
	/* Print everything thereafter */
	/* The first time around this will just print the last array index */
	while(j < n)
		printf("%d", nsys[j++]);
	putchar('\n');

	if(nsys[i] == (m-1))
	{
		/* Find the last array index less than (m-1) */
		for(j = i; nsys[j] == (m-1) && j >= 0; j--)
			;
		/* If there is not one then we are all done */
		if(j < 0)
			break;
		else
		{
			/* Increase it and set everything thereafter to zero */
			/* Except the last array index (units) */
			nsys[j]++;
			j++;
			while(j < i)
				nsys[j++] = 0;
		}
	}

	/* Increase the last array index (units) */
	if(nsys[i] < (m-1))
		nsys[i]++;
	else
		nsys[i] = 0;

	/* Pause every ten iterations */
	if(k++ == 9)
	{
		k = 0;
		printf("\nPress any key to Continue or Ctrl-Break to Quit.\n");
		getchar();
	}
}


Thank you all very much for all your help. That includes you Mr.
Nebinger.

adios,

Re: [Dev-C++] port access???

[Kevin W. <ke...@me...>]

If you are writing a Windows program, use CreateFile for serial and parallel
port access.
This is the recommended way, but (except for WinNT) you could use assembler
code.

I have not tried parallel port access under Windows32. Using CreateFile
seems more complicated than the "old" way, although most of the parameters
mentioned in the SDK are for serial port access.

Re: [Dev-C++] Detecting running applications

[Kevin W. <ke...@me...>]

Perhaps the window-enumerating function is what you need?
When you identify the correct window, you could then call
SetForegroundWindow

Kev.

(From the Windows
SDK)......................................................................
The EnumWindows function enumerates all top-level windows on the screen by
passing the handle of each window, in turn, to an application-defined
callback function. EnumWindows continues until the last top-level window is
enumerated or the callback function returns FALSE.

BOOL EnumWindows(

    WNDENUMPROC lpEnumFunc, // pointer to callback function
    LPARAM lParam  // application-defined value
   );


Parameters:

lpEnumFunc
Points to an application-defined callback function. For more information,
see the EnumWindowsProc callback function.

lParam
Specifies a 32-bit, application-defined value to be passed to the callback
function.


Return Values:
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero.

Remarks:
The EnumWindows function does not enumerate child windows.
