[Dev-C++] Webupdate under Win98

[Martin D. <nex...@qu...>]

I'm running Windows 98SE with latest updates and the latest version of =
Dev-C++ seems to have trouble moving downloaded devpaks from =
C:\Windows\Temp (I get message about verifying my permissions to install =
packages). I didn't have any problem with previous versions.

I'd also like if the comment/decomment shortcuts would be something =
different from Ctrl+Alt+, or Ctrl+Alt+. because those two shortcuts =
interfere with '<' and '>' marks on my keyboard (I'm using Czech =
language set which has those two marks accessible only by pressing Alt =
Gr+, or Alt Gr+. which result in commenting/decommenting the line I'm =
writing in).

Re: [Dev-C++] while termination problems

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

Also, you should _not_ compare floating point numbers with == and != since
floating point numbers - even if looking ok in a printout - are often
inexact, i.e. have a bit of noise in the last value digits. If you think a
variable has the value -1, it might just as well have the value
-1.0000000001 which obviously would make your compare to fail.

Your test should in this case instead have been
  if (acctnum < -0.5) break;
which would break for -1 while not breaking for 0.

Normally the general floating point compare for equality would look like:
  if (fabs(acctnum - -1) < EPS) break;
where EPS is a suitably small number. Note that EPS must be larger for
float variables than for double variables. Also note that EPS must be
larger, the larger numbers that are compared.

Re: [Dev-C++] while termination problems

[Reid T. <rei...@at...>]

as a note, you should avoid using C and C++ headers in the same program, 
use cin.get rather than system("PAUSE") to keep your window around.  You 
should also initialize your variables before using them.
not sure if this is what you mean,,,... but....

#include <iostream>
#include <iomanip>

using namespace std;

int
main(int argc, char *argv[])
{
    /* arbitrarily initializing all of these to 0 */
    double acctnum = 0;
    double bBal = 0;
    double nBal = 0;
    double charges = 0;
    double limit = 0;
    double credits = 0;

    while (acctnum != -1)
    {

        cout << "Enter account number (enter -1 to end): ";
        cin >> acctnum;
        if (acctnum == -1)
        {
            break; /* break the while loop */
        }

        cout << "Enter beginning balance: ";
        cin >> bBal;

        cout << "Enter total charges: ";
        cin >> charges;

        cout << "Enter total credits: ";
        cin >> credits;

        cout << "Enter credit limit: ";
        cin >> limit;

        nBal = bBal + charges - credits;

        cout << "Account:" << setw(13) << acctnum << "\n";
        cout << "Credit Limit:" << setw(9) << limit << "\n";
        cout << "Balance:" << setw(14) << nBal << "\n";

        if (nBal > limit)
            cout << "Credit Limit Exceeded.\n";
    }

    cin.ignore();
    cin.get();
    return 0;

fopen returns NULL if it fails and sets errno.

If i remember well, there is a variable named errno, this have the
error after a system call fail, if you need a string of the error, you
can use perror or strerror.

Re: [Dev-C++] Dev C++ 4.9.7.0

ß ö R N L ë G ë N Ð wrote:

I do not know if you could write that in 4.9.7.0 but if so I sureley 
would not write that. It implies iostream is a C header. Streams however 
are C++. In C++ you normally wirte headers like #include <iostream> 
(withouth the dot h).
So instead of switching to an older version of the IDE (which has, as 
Per did mention, nothing to do with the actual compiler, and therefore 
his pickiness on syntax) it is maybe a better idea learning to use the 
C++ header notation for C++ headers.

Using antique headers however, should not give compile errors, only 
warnings. It is strongly deprecated to use C-style headers since support 
might be dissapear in the future, but it should work with the compiler 
delivered by 4.9.9.0.

  Hielke

Re: [Dev-C++] Dev C++ 4.9.7.0

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

It's syntax? Are you talking about the actual compiler?

The compiler and the IDE are two separate things. 4.9.9.0 is the version
of the IDE. You may use this IDE with just about any version of the MinGW
compiler you like.

The only think to notice is that the library packages installed with
Dev-C++ are built with specific versions of the compiler so if you make
too large step in MinGW version, you will have to rebuild any extra c++
libraries yourself.

Good Morning:

     DEV is an IDE not a compiler.=20

     I suggest you use the Microsoft compiler, and quit bugging =
everyone.

     If this is in a foreign language, Learn it.

  Using code in this way requires a compiler that works the way you

  Switch off MS specific language extensions on your MS-compiler (/Za).

I do not think so, but they are silently encouraged to be polite.

Re: [Dev-C++] OpenSSL

[Vivek J. <viv...@ya...>]

www.openssl.org

You should find the documentation as well as the file
there. If you are looking for something related to
HTTP, HTTPS, FTP or one of these protocols a better
place would be http://curl.haxx.se/

[Dev-C++] OpenSSL

[Dmitry S. <si...@si...>]

Hello, dev-cpp-users.

I have the following code

EVP_MD_CTX crypt_ctx;
EVP_MD_CTX_init( &crypt_ctx );
EVP_VerifyInit( &crypt_ctx, EVP_md5() );
EVP_VerifyUpdate( &crypt_ctx, msg, msgsize );
EVP_VerifyFinal( &crypt_ctx, sign, signsize, pubkey );
EVP_MD_CTX_cleanup( &crypt_ctx );

This code is compiled as well, but when I try to run my program, I get
an error that entry point for function EVP_MD_CTX_init not found in
libeay32.dll.

Does anybody use libeay32.dll?

are people being actively encouraged to post on the list in random

Re: [Dev-C++] Nested Structures in a Database.

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

You just have to add an extra field to store the container id.

To connect items you need relations, and relations need something to match
against. Hence an extra field.

[Dev-C++] Nested Structures in a Database.

[David M. <dml...@co...>]

What is the best structure to use when saving nested data in a database?

I wantto use an embeded database to store character info and am a bit 
stuck on the inventory. How do I use the databse to handle container 
items which can have items in them. If possible I am interested in a 
method that would allow me to nest indefinely (let the code limit how 
far we can nest).

So far the best I can come up with is an extra field which can be NULL 
and has the item number of the object it is contained in. I was hoping 
to not have to add another field to do this.

Any thoughts appreciated.
