Re: [Dev-C++] Windows95 Shell and COM

[<or...@vp...>]

Hello va13ak!

> I have a little problem with compiling project using Windows95 Shell
> and COM. Does anybody know how to compile, for example, next example ?

First, I want to tell you, that I have absolutely NO C++ experience, and I don't 
know ANYTHING about C++ (yet :), although I have been programming in C for quite 
a while now, and I know a lot in it.

I hope you want to compile it with gcc (from Dev-Cpp) not from MSVC. So first 
you need to import the treesize.dsp. It was done correctly with Dev 4.9.6.8.

Warning:
You should know, that your program is obsolete. It uses deprecated C++ headers 
(iomanip.h, etc.). You should update your files, although it still works.

Here are the corrections that I have made, regarding the errors, that gcc 3.2 
reported to me:
1. In file main.cpp:
    At line 9 write this:

void NewHandler ()
{
     throw WinException ( "Out of memory" );
}

// Instead of:

// int NewHandler (size_t size)
// {
//     throw WinException ( "Out of memory" );
//     return 0;
// }

    At line 58 write this:
    set_new_handler (&NewHandler);

// Instead of:
// _set_new_handler (&NewHandler);

2. In file controller.h:
    At line 8 write this:
#include <strstream.h>

// Instead of:
//#include <strstrea.h>

//Note: THIS header is also deprecated


After these corrections click compile in Dev :)

I hope I could help.

The above program compiles perfectly from Dev-C++ (4.9.6.8), and even from a 
command prompt. I have MinGW (gcc 3.2) separately installed. The command is:

g++.exe code.cpp -o code.exe

I think there may some installation/corruption problem with your gcc. If you 
could post the errors, I would be able to help you more.

[Dev-C++] C++ compiling problems

[Matthews <dem...@uw...>]

I've been trying to teach myself c++ recently, so I started out with this
basic program.

#include <iostream>
#include <cstdlib>

int main()
{
  using namespace std;
  cout << "Hello.\n";
  cout << "Press ENTER to continue.";
  getchar();
  return 0;
}

I attempted to compile this in Dev-C++ 4.9.7.0, which I downloaded with
gcc3.2 packaged along with it.  172 errors are given, which all seem to be
based off of a missing "c++config.h" which is included from iostream.  So,
I try to find the header file.  The one I get is faulty, so I abandon it.
Reinstalling doesn't put it in, I tried twice.  In a last-ditch effort, I
reinstall Dev-C++ 4.9.5.0 which I downloaded packaged with gcc2.89 (or
whatever the one before 3.2 was.)  Compiling the same program (except with
changing the <iostream> to <iostream.h> and also including <stdio.h>) works
perfectly.  It appears as though I'll be doing my c++ coding in 4.9.5.0 for
now, but can anyone help me figure out the reason for this?

RE: [Dev-C++] EXCEL files as a datasource

[Marc H. <ma...@e-...>]

Hi,

There is a OleDB datasource provider for Excel. The trick is in the
connection string which should be something like:
"Provider=Microsoft.Jet.OLEDB.4.0;Data
Source=F:\agasp\samp\excel.xls;Extended Properties=Excel 8.0;" where the
Extended properties give the version of Excel to use. You can use ADO as
well (as ADO simply wraps OleDB). You'll probably want to find some kind of
class library to do this. I know you can also use ODBC to connect to Excel
spreadsheets, but I'm not sure how.

Some information here:
Using ASP to connect to Excel:

A ADO wrapper for use with VC:

Subject: [Dev-C++] EXCEL files as a datasource



I trying to use DEV C++ (and the built-in compiler of course) to access MS
EXCEL files. The basic idea is to use an  EXCEL file as a data source for my
C++ code. 

Any one have any ideas or experience on this matter ? Is it an easy or
complex thing to do ?

Any help would be appreciated

Re: [Dev-C++] failure to execute

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

Select Tools/Code Generation

Uncheck checkbox 'Use fast but imperfect dependancy generation'

If this doesn't solve your problem, are you running on a mounted file
system, i.e. are the source files stored on a file server. In that case,
you might get synchronization problems between the clock on the computer
and the clock on the file server.

[Aimee S. <Ai...@ca...>]

Greetings;
   I was working with my students last night on Dev-C++.  We encountered a
few problems -- the most perplexing one being that when they altered the
code and then rebuilt the prog. then executed it, the previous program was
run and had not rebuilt/complied the altered code.  
If we copied and pasted the program into a new environment then it worked
just fine.  
This was not a consitent error, just an infrequent one but I wouldn't have
thought that it would have happened at all.  
Is there something that I can do to sort this out or did I not tell them
something that I needed to?

RE: [Dev-C++] using 2 .c files

[Jaap de W. <wo...@Ne...>]

c++ is not c.
By defining CServer, you define a new object type.
Your compiler has to know from both implementation files how the class =
is
defined.
The usual way to do this is putting the class definition in a header =
file,
and include it in both implementation files eg:

MyClass.h:
class MyClass{
	MyClass();
	void anyFn();
	...
};
MyClass.cpp:
#include "MyClass.h"
MyClass::MyClass()
{}
void MyClass::anyFn()
{}
main.cpp
#include "MyClass.h"
main()
{
	MyClass myclass;
	myclass.anyFn();
}

Re: [Dev-C++] EXCEL files as a datasource

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

Bad idea. Definitely complex.

If you really, really, really have to, you can communicate with a running
Excel application and send/receive data, but it isn't easy. And trying to
read and/or write *.xls files are not something you want.

If you need to share data between Excel and your program, it's easier  to
let Excel access the data from an alternative source.

Export/import of comma-separated text files, storing data in an Access
database etc.

[Dev-C++] Windows95 Shell and COM

[va13ak <va...@uk...>]

Hi, all !

I have a little problem with compiling project using Windows95 Shell
and COM. Does anybody know how to compile, for example, next example ?

[Dev-C++] vUpdate stuff

[Matthews <dem...@uw...>]

Whenever I try to run vUpdate it always crashes while downloading a
package.  I've only had one package get through, which was Akrip.devpak.
I'm not asking for help with vUpdate, unless you want to try to figure out
my problem.  Is there another place I can download the packages from,
without vUpdate? (eg. through Internet Explorer)

Each file you make must have the definitions of all the objects you use in

Your file main.cc uses the class CServer, but it does not have a definition
of it.
You can put  the declaration of class CServer in a header file and include
that header file in server.cc and in main.cc

I do´nt understand exactly what your second problem is, but I think it might
be that
server.cc does not have the object db_connection you define in main.cc
You can try to add in server.cc:

extern Connection db_connection;

before you work with the connection.

[Dev-C++] EXCEL files as a datasource

[Louis G. <lg...@ya...>]

I trying to use DEV C++ (and the built-in compiler of course) to access
MS  EXCEL files. The basic idea is to use an  EXCEL file as a data source
for my C++ code. 

Any one have any ideas or experience on this matter ? Is it an easy or
complex thing to do ?

Any help would be appreciated

[Dev-C++] using 2 .c files

[Steve B. <iac...@no...>]

Hi there, this is my first post, so please forgive me if my message is 
out of context for this list.

I am building an application in c++ on freebsd, and can't get 2 .c files 
to merge properly.  When I compile, I get 'undefined CServer' when I 
compile. I tried defining the 'server' variable with extern, but I don't 
know if I was using extern in the proper context. For instance, here are 
snippets of the 2 files:

-----snip server.cc--------

#include "myheader.h"

class CServer {
    int var1;
    int var2;
    string var3;
    string var4;

    void addServer(int, string, string);
}

void CServer::addServer(int a, string b, string c) {

var3 = c;
var4 = b;
var3 = a;
}

--------end snip server.c-----------

------snip main.cc-----------

void main() {

CServer *server;                    // The problem is here.
server = new CServer;

server.addServer(feedvar, feedvar, feedvar);

/* Do some other stuff */

----------end snip main.cc---------

Another problem: In this same program, I would like main.cc to connect 
to a mysql database early in main(), then allow the server.cc file (more 
specifically, the member functions of CServer) to read/write to the db. 
 I know the mysql syntax is correct, as when I put all of the code in 
one file, everything works ok.  Is this another extern problem?  What 
part of the mysql code to I have to initialize with extern and where? 
 Example:

main.c------

// all of the mysql db stuff defined and included in 'myheader.h'
#include "myheader.h"

main() {

Connection db_connection;
db_connection.connect(//send db info here)

end snip main.c----------

Eventually, the server.c file opens up a table, then does it's thing, 
but when compiling, it seems as though the database connection doesn't 
even exist (from the point of view of server.c).

What is the easiest way to link these 2 files so they merge and appear 
as one?  Or is that the purpose of extern?  I simply want to divide up 
my code so I can have 'modules' written in each .c file to make it 
easier to maintain.

Thanks for any help in advance.

[Dev-C++] paste a file in another file

[Ricardo R. <ri...@po...>]

if I want to write a text line in a file
I can do that in the way:

*********************
FILE *pf ;
......
fprintf(pf, "hello baby");
..............
**********************

but if I want to include the text file
'hello.txt' in the file pointed by 'pf',
how can I do that ?.

thanks in advance,
Ricardo.

you should add to the linker settings in the project options dialog

-lglu32 -lopengl32 (and if you use glut:) -lglut32

if you use glut try to compile it as win32 console, else as a win32 GUI 
application

check the header #includes at the top of program because it is possible 
that there are missing the "gl/" pathes :

#include <gl/gl.h> correctly, not <gl.h> (this applies for glu.h and 
glut.h too)

RE: [Dev-C++] debugging macros

[Marc H. <ma...@e-...>]

Hi Per,

Once again you have helped me immensely. DebugView has been successfully
integrated into my programming arsenal, and it is exactly what I needed.
It's a pity that Dev-C++ does not have a DebugView like feature built in,
but such is life. Perhaps in the future.

Create your own TRACE #define that calls an own-made function using
sprintf() to a buffer, and then emitting the buffer to the windows function
OutputDebugString().

That way, you may use any windows debugger or debug tracer program and view
the debug output while running your program.

If you go to www.sysinternals.com, you can download a nice program
DebugView, that will connect to the windows debug stream.
