Any graphics in C/C++ generaly requires a lib of some sort.  
DirectX, and OpenGL are used often for Windows programs, and 
Allegro works well for Console things if you can get it to work.

The only other option is to learn a LOT more about PC hardware 
than most sain people desire too....

Did anyone answer this one? I would like to know how to use graphics in the=

I'm using nearly the same tools exept my Dev-C++ version counts 4
I've some trouble with the Insight debugger too.

I) During a debugging session the source-code doesn't get shown anymore.
   This happens most times when I step into a function which is contained in

  a different file than the current one

II) The debugger seems to hang up in a endless loop or something.
     Windows gives me the hour glas while pointing on the debugger
     (I own a 500MHz AMD, 96MB RAM)
    Restarting the debugger somtimes help somtimes don't (it crashes)

Are there any non console alternatives?

You need the function atof(). This function and atoi() and atol()
 are declared in stdlib.h

Hope this helps

 Alan,
 
char(10) is '\n', the line feed character. When you paste into
 Notepad you get the solid block in Microsoft's edit boxes
 (Notepad is a simple edit box) unless you add also the char(13),
 ie '\r' the carriage return.


Hope this help.

    I`m having a strange problem.   I am writing a program that decodes =
a file (holds calendar data) and encodes entries for appending to the =

I'm running version 4.01 of Dev-C++ under Windows 95 with the Mingw
2.95.2-1 compiler.  I have also been using version 4.18 of gdb
"configured as i386-mingw32."

Recently I downloaded the Cygnus Insight debugger from the Bloodshed Web
site.  Now I show the gdb version as 19991101 which is "configured as
i586-cygwin32."

Insight exhibits some strange behavior:

a. Sometimes setting a breakpoint at a particular line in one program
module results in the setting of a breakpoint at the same line number in
another module instead.

b. Attempting to view the Memory window causes an invalid page fault and
Insight crashes.

c. The Insight Run, Step, Next etc. buttons do not appear to work.  The
Run, Step, Next etc. commands do work correctly in the Console window
though.

Should I be using the Cygwin compiler instead of Mingw or should I look
elsewhere for the solution to these problems?


Chuck Brockman

in c you would use this:
#include <math.h>
double atof(const char *s);

I tried to build a win32 console app using the netapi32.dll function
NetScheduleJobAdd (#include <lm.h>, ...)
After linking, i get the error "c:\tools\dev-c++\projects\atsubito
1.00\atsubitomain.o(.text+0x22f):atsubitomain.c: undefined reference to
`NetScheduleJobAdd@12'"

Can anyone give me a hint on what to do (I#m a newbie to C / C++)

TIA, Stephan

Hi all,
stupid question maybe, but I couldn't figure out a solution so far...
After compiling and running a program, i'd like to look at the results
or any output, but the console window disappears immediately. How do i
prevent this?
thanks Tilman

Hi there...

How do I convert a string (like "7.25") to a float?

Thanks! :)

-------------
#define stone

you can do two things :

one option is that u include the <conio.h> header file in ur proggie and use
the
getch();
after the output statement, or at the end of the program

or you can press alt + F5 to view the output
