When I select 'Auto open', 'First project file' it never seems to work? 
Is this a bug? Btw I'm using 4.9.9.2.....

I was wondering if I could open the Date and Time Properties Dialog Box wit=
h any Win32 function if, for example, a user clicked a button or something =
in my program?

Yes, there are a way to call a constructor late. The method is used when
creating an object in an already existing memory buffer.

However, note that a constructor normally affects all fields - and
allocates resources - so you do not want to run the constructor multiple
times.

If you want to reset the object to an initial value, you should instead
create a method init() - or possibly clear() - and have the constructor
call this method.

Once more, you do not want to call a constructor multiple times! If the
constructor allocates memory, you would get memory leaks.

is there a way to call a constructor on a class after the object has  
been created?

simply put, I wish to create an object, perform operations on it,  
then modify it using it's constructor

is this possible?

why is this always in HTML when plain text will do just as good

now this is not your daily 'i forgot WinMain in my windows application'
question but a more complex one.

what i have is a game engine based on heavy modularization. especially
the start-up code is outside the .exe running the engine. hence i have
the game engine in the shape of a .dll file providing entry points for
whatever system you want to run it on so that the user doesn't have to
worry. for windows systems the entry point looks like this:

>>> CODE
int WinMain( HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR
lpCmdLine, int nCmdShow ){
=2E..
}
<<< CODE


in the launcher file i simply subclass an application class which keeps
a 'theOneAndOnly' type variable of the app-object. hence the launcher
simply links against my library and provides this subclasses object and
all is working. on my linux box this works like a charm. on the windows
machine with Dev-C++ compiling i reveive a linker error about WinMain@16
missing. it is though part of the linked library and correctly exported
( shows up in the .def file ). what can be wrong? why does the linker
not eat this?

i set the project to be 'Windows Application' without compile/link
options except -ldragengine ( =3D> libdragengine.a in dev-c++/lib ) so i
don't see a problem there. if i compile the library directly as .exe
instead of .dll it does link hence the function is there and recognized.
it simply doesn't work if i link it into an external project not having
WinMain.

Hi there:
 
I'm in use of Dev C++ 4.9.9.2
 
I get a g++ 255 make error.
 
It says to me: "Line is too long"
 
Compiling is correct.
My problem is in linker process.
 
 
Any ideas?
 
 
Thaks in advance.
 
 

How can I make my MS-DOS program understand special character input =
(<ALT> combinations) from the keyboard? E.g. when I type <ALT>164, I =
wanted =F1 to be displayed.

I use curses wgetch(), but this does not seem to catch special =
characters (<ALT> combinations), all normal characters are displayed =
fine.

Thanks in advance,

Patrick Hens

MSDOS in itself doesn't support a cursor color, just a cursor size, i.e.
upper and lower scan line.

I don't think that M$ have made any extensions for the 32-bit command line
interface when run in window mode since the original MDA and CGA hardware
doesn't support cursor color.

"graphics.h" is delivered only by Microsoft and Borland compilers(as far =

as I know), because it is not part of ISO C++ standard so other compilers=

don't have to provide it.
"kbhit()" funtion has the same condition. Compilers are not forced to =20
implement is (because is not part of the ISO standard) so you shouldn't =20
expect any compiler to provides this.

Is it possible with DEV-C++ to see memory addresses while in debug mode?
Thanks

You haven't shown the full code for your objects, but...

The inner loop seems to add multiple entries to the SEQ hash.
The outher loop removes a single entry from the SEQ hash.

That makes SEQ constantly growing, making SEQ.size constantly growing.

Note that for most container classes (STL or home-grown), it is
problematic to iterate through all elements while at the same time add or
remove entries.

for(int j=0;j<SEQ.size();j++){
			
	for(int k=0;k<codons.size();k++){
				
		SEQ.add(SEQ.get_keys()[j]+codons[k],1);
				
	}

}

above is the code I'm using.

SEQ is an object of my own devising called "Hash"

it functions exactly like an STL vector, except instead of having  
integer values call the data, it has a string key that calls data.   
for those of you who know perl, you know exactly what I'm trying to do.

codons is a vector <string>

can anyone give me any insight towards why the outer for loop is  
infinite?

SEQ.remove(j) is like saying vector <string>::erase

how do I create a pipe to command line such that I can send  
information to a process such as top?

Hello,

  What are the diferences between them? Why did Borland build a differente
compiler?

  Are there other versions of C/C++ compiler? Which of them follows the ANS=
I
standard?

  Thanks in advance.

Hello Friends,

I need a dll sample in Dev C++. I want to call functions from VB6.

You can store iterators, pointing to the elements in the first list, to 
the second list. Only don't forget, that iterators become invalid after 
adding or removing elements from the first list.

Hello:

I hope this example could help you.

Regards.

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

main(){

    long x,y,z;
    scanf("%lx",&x);
    x = x & 0xffffffff;          /*number of bits = 32 */
    y = x & 0xff000000;         /*MSB = most significant byte */
    z = y >> 24;                /* shift right 24 bits */
    y = x << 8;                 /* shift left 8 bits */
    y+=z;
    printf("\n%lx\n",y);
    system("pause");
    return;
