[Dev-C++] Is a struct preserved when used into a cpp file?

[Vinicius <cvi...@uo...>]

Hello,

a) I have a .h (header file) that declares a struct:
...
typedef struct {
   UINT4 state[4];  /* state (ABCD) */
   UINT4 count[2];  /* number of bits, modulo 2^64 (lsb first) */
   unsigned char buffer[64];  /* input buffer */
} MD5_CTX;
...

b) and I have .c (C source file) that uses the header above:
...
void MD5Init(MD5_CTX *context);
...

c) I have created a .lib (library file) with the functions above.

I have used the header file above into a .cpp (C++ source file). The .cpp
file uses the .lib functions, but the compiles says "Unresolved external
MD5Init(MD5_CTX*) ...".

I think the .lib was included correctly on the project, so is a struct
preserved when used into a cpp file?

Thanks in advance, Vinicius.

PS: I'm using actually the Borland C++Builder 3 IDE for this project, but my
doubts is concerned about the theory, excuse me for anything.

RE: [Dev-C++] Using namespace std

[Daniel G. <sp...@ho...>]

You could use GDI to draw shapes and lines. For collision detection put a 
bounding box around the circle and for the corners perhaps put a conditional 
statement in that lets another body pass into the bounding box by X pixels 
but no more. It depends how detailed you are going to do it.

Try looking up modelling a kettle on the web - many physics students create 
animations that bounce a kettle around inside a box. This is because it is 
an odd shape and is difficult to do, but it is a famous example.

[Dev-C++] Problem on XP Professional

[Mohammed I. <mi...@ac...>]

Hi...


I wrote a a large program with Dev-C++ on Windows XP Professional. The
compilation went smooth for three hours and the program ran fine. There's
only one problem I can't find the reason for it. Some parts of my program
when I try to use produces an error message saying that some portion of
memory can't be written. Why?

[Dev-C++] Win32 API tabbed dialog

[Ed C. <em...@to...>]

Hello,

I'm looking for some guidance on a Win32 API question. I have a dialog =
that
has lots of different options, too many to put on a single dialog
reasonably, but it lends itself well to a tabbed display, with certain
groups options on each page.

Here's the problem: I have never built a tabbed dialog like this, =
before,
and can find relatively little of use through Google or MSDN. I can get =
a
simple dialog based on the Win32 TAB control or on the Property Sheet
controls. Property sheets seem easier, in most respects, but it's =
unclear to
me whether or not I can put anything in the dialog box other than =
property
sheets. There are a few controls - mostly buttons - that I would like to
have visible below the tabbed portions.

Should I use the TAB controls? I'd like to get this right before coding =
the
whole thing.

Thanks!

Hello,

 I looked in the Output Debugger message, and says simply:

 I changed the Project Options to reference "main.exe" as the output... but
 nothing happens, the error continues... I already put the -g3 parameter in

Re: [Dev-C++] My First Program

[Maya <Esc...@ne...>]

You know what I would do? I would solve the whole thing by not using the 
char array, just use the std::string.
The program is a C++ program, and as a C++ programmer you have to master 
the object oriented paradigm. Forger about char, that's a more 'C' kind 
of style!

Have good one!!

RE: [Dev-C++] Windows XP Home edition

looks to me like -lobjc means you've setup your project to link with the

C or C++ program, remove the reference to link the objc library.  I
believe that:  g++: -lobjc: linker input file unused since linking not
done may mean that '..you asked to link objc, but your code doesn't use
it, so i'm not linking it to your program'..

Re: [Dev-C++] My First Program

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

Since char xx[] is a native type, there are no built-in functions
available for character arrays. If you want to perform any operations, you
must call the global functions declared in string.h.

// Compare first 3 characters in array
if (!strncmp(inbuf,"ZIP",3))

// Locate a substring anywhere in the character array
if (strstr(inbuf,"ZIP"))

Re: [Dev-C++] How to update beyond 4980? (vUpdate is barking at me)

[Doug M. <dou...@al...>]

Egg on my face.  I usually have "search hidden files and folders" 
checked in the search dialog, but it was unchecked when I looked just 
now.  That's why it didn't find the Dev-Cpp.cfg file.

It's also odd that when I retried the "Tools->Check for 
Updates/Packages..." just now, the complaint about $INCLUDE field was no 
longer there.  You'd think it would have the consderation to break 
consistently, but no.... 8^)

Thanks,
Doug

Re: [Dev-C++] My First Program

[Doug M. <dou...@al...>]

Hi Ken,

It's hard to tell what's going on without any variable declarations or 
code comments.

Two things are interesting about your code.

First the hang you are seeing.  Do you know that the construct

	while (MtgCode0 == "W") MtgType=12;

repeats the assignment 'MtgType=12' over and over, as long as the 
expression 'MtgCode0 == "W"' remains true?  This line will do one of two 
things.  It will drop through without doing the assignment if MtgCode0 
!= "W".  Or, if MtgCode0 == "W", it will hang.

You probably wanted straight-through conditionals rather than loops, 
something more like:

	switch ((int)*(char *)MtgCode0) {
	case 'P':
		MtgType=10; TotP++; break;
	case 'L':
		MtgType=11; TotL++; break;
	case 'W':
		MtgType=12; TotW++; break;
	default: TotOther++;
	}

However, if I understand your intent, there may be another problem 
lurking in your code snippet.  I hope you realize that in the expression

	MtgCode0 == "W"

you are checking for equality of the value contained in the variable 
MtgCode0 with the _address_ of the literal string "W".  This code is not 
performing a string match!  In C and C++, the runtime value of a quoted 
string literal (e.g., "W") is the memory address of its first character 
- not the char's value.

But, you may say, I've used code like this before, and the comparison 
does work when I've assigned "W" to MtgCode0!

Well, yes, it has happened to work, but only because of a fact about how 
the compilers generate code.

I'm guessing that prior to reaching this part of the program, another 
part of the code assigned the value "W" to MtgCode0.  Right?  When you 
compiled the program, the compiler noticed that you were using the 
string literal "W" in more than one place, and its codegen combined the 
first "W" (the one you assigned to MtgCode0) and the second "W" (the one 
in the equality test) into the same object.  Compilers like to economize.

So, when you earlier assigned "W" to MtgCode0, you were really assigning 
its address to MtgCode0.  And later, when you checked MtgCode0 against 
"W", you were really testing the _address_ contained in MtgCode0 against 
the _address_ of [the same code object representing] "W".

This works as long as the compiler likes to economize with its code 
generation of string literals, AND is able to do so.  That's a risky 
assumption to make.  Suppose you assign the "W" in one subprogram in one 
file, let's call it doubleyoo1.cpp, and test equality with "W" in a 
second subprogram in a different file, doubleyoo2.cpp.  Suppose further 
that you compiled the two at separate times and then linked them. 
Dollars to donuts, there will be two copies of "W" in the resulting 
binary, and the equality test will fail.

You'd be safer using the single-quoted 'W' (an int value containing the 
ASCII code for doubleyoo) rather than "W" (the address of a 
compiler-generated, zero-terminated, length-two C string containing the 
ASCII code for doubleyoo).  If you look back, you'll see that is what I 
have done in my suggested replacement for your "while" and "switch" blocks.

Hope this helps,
Doug

Re: [Dev-C++] HELP: in MSW testing program for Linux

[Maya <Esc...@ne...>]

To me the name GCC is synonymous with EVERY_WHERE. You can very easily 
say: "This code has to compile not only in this machine and that one, 
but EVERY WHERE!"; meaning that you want this code to be GCC compliant.
There is no doubt, GCC is portable to... all common / feasible  machines 
out there.
I have use most of the C/C++ compilers in the market, MS or Borland for 
their speed and the others for the heck of it, but I have come to 
accept  that clients don't care about waiting 2 or 3 nanoseconds, but 
get really P.O. when I tell them that the project would have to be 
extended for another 2 or 3 weeks due to code incompatibility.
No doubt, GCC *is* the way!
For future reference, I cannot say that it was my idea to use GCC, that 
credit goes to one of my kids.

Man, you must need some time away from the every day vida loca :). I

I know that IT can gobble you up, but it is good to be aware that even

Take it easy for a day or two, please?

Have a good one

Okay. If you are running Windows XP, it should be under  Hard Drive 
Partiton:\Documents and Settings\Your Username\Local 
Settings\Application Data.
You may also download Dev-C++ 4.9.8.5 from the site.

Jens,

I looked in the Output Debugger message, and says simply:
"Executable file could not be loaded in the debugger"

I changed the Project Options to reference "main.exe" as the output... but
nothing happens, the error continues...
