when I'm trying to compile it gives me 26 errors however everything is at its right place
but won't able to understand the errors mostly constant is too long.
Plz help I want to play a mp3 file through C programming.
*errors are shown in the jpg image
#include "inc/fmod.h"
FMUSIC_MODULE* handle;
int main ()
{
// init FMOD sound system
FSOUND_Init (44100, 32, 0);
// load song
handle=FMUSIC_LoadSong ("don.mp3");
// play song only once
// when you want to play a midi file you have to disable looping
// BEFORE playing the song else this command has no effect!
FMUSIC_SetLooping (handle, false);
// play song
FMUSIC_PlaySong (handle);
// wait until the users hits a key to end the app
while (!_kbhit())
{
}
//clean up
FMUSIC_FreeSong (handle);
FSOUND_Close();
}

Borland Turbo C++ pre-dates most C++ standards and modern C. I would not expect FMOD or any modern library to work with this compiler.
Visual C++ is free to use in the Express form, and is a vastly better compiler.
The code you have listed is FMOD 3 code, yet you are using FMOD 4 headers (and probably libs too). This will not work, I can see from your error pic you have other troubles too, perhaps include paths not being set correctly.
We provide a Borland lib that you will need to link with: 'fmodex_bc.lib' but again this is FMOD 4 code, I would highly recommend looking at the 'playstream' example that ships with the SDK, it demonstrates MP3 playback.

I am trying to make a graph using graphics.h in c++. I was following a tutorial on youtube. It seems that either due to the age of the video (perhaps the syntax has changed slightly?) or a problem on my end; I cannot even get a separate window for my graph to open. I am in completely uncharted waters for me as the limit of my coding knowledge is what you would expect to learn from a first-semester coding class. I am using DEV C++ and am compiling using "TDM-GCC 4.9.2 32-bit Release" (because the 64 bit release gives me an error in "Makefile.win" that scares me) and my program exits with a return value of 3221225477. What am i doing wrong?
#include"graphics.h"
#include<math.h>
#include<conio.h>
#include<iostream>
using namespace std;
int main() {
initwindow(800,600);
int x,y;
line(0,300,getmaxx(),300);
line(400,0,400,getmaxy());
float pi=3.14159;
for(int i=-360;i<=360;i++){
x=(int)400+i;
y=(int)300-sin(i*pi/100)*25;
putpixel(x,y,WHITE);
}
getch();
closegraph();
return 0;
}
According to your issue and exit-code, the return value in hex is 0xC0000005 or STATUS_ACCESS_VIOLATION. But most developers didn't even bother to learn out-dated legacy API and I can not help you to find the exact line (use debugger, it shows you the exact line, still not the reason).
But to answer your question in the title, well, according to what free framework one uses (Qt or XWidget), the method differs, for Qt (which I would recommend) simply override paint-event and use QPainter renderer to show your QPath data.
Don't reinvent the wheel (or render-system in this case), your course and/or book may soon introduce you to one of the mentioned frameworks.
I am new to c++ programming , today i was trying to save an image using CImg .
CImg is C++ Template Image Processing Library .
The basic code i wrote is(Please forgive any syntax erros , as copied part of my codes) :
#include "CImg.h"// Include CImg library header.
#include <iostream>
using namespace cimg_library;
using namespace std;
const int screen_size = 800;
//-------------------------------------------------------------------------------
// Main procedure
//-------------------------------------------------------------------------------
int main()
{
CImg<unsigned char> img(screen_size,screen_size,1,3,20);
CImgDisplay disp(img, "CImg Tutorial");
//Some drawing using img.draw_circle( 10, 10, 60, RED);
img.save("result.jpg"); // save the image
return 0;
}
But I cannot run my program as it says :
Invalid Parameter - 100%
'gm.exe' is not recognized as an internal or external command,
operable program or batch file.
This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

terminate called after throwing an instance of 'cimg_library::CImgIOException'
what(): [instance(800,800,1,3,02150020,non-shared)] CImg<unsigned char>::save_other() : Failed to save file 'result.jpg'. Format is not natively supported, and no external commands succeeded.
Though i can see the image , I cannot save it.
After googling a bit i found people saying to install ImageMagick , i have installed it but no help .
Some of the Forum says to compile against libjpeg, libpng, libmagick++. But i don't know how to compile against those libraries.
I am using Eclipse CDT plugin to write C++ project .
Please help me .
I had the same error, and installing of GraphicsMagick (not ImageMagick) helped me.
I've downloaded and installed GraphicsMagick-1.3.26-Q8-win64-dll.exe from ftp://ftp.graphicsmagick.org/pub/GraphicsMagick/windows/. You may choose another one, if you need:
Note that the QuantumDepth=8 version (Q8) which provides industry
standard 24/32 bit pixels consumes half the memory and about 30% less
CPU than the QuantumDepth=16 version (Q16) which provides 48/64 bit
pixels for high-resolution color. A Q8 version is fine for processing
typical photos intended for viewing on a computer screen. If you are
dealing with film, scientific, or medical images, use ICC color
profiles, or deal with images that have limited contrast, then the Q16
version is recommended.
Important: during installation, don't remove checkbox "Update executable search path", which updates environment variable %PATH%, making gm.exe available from any place.
In my case, it was also required to install Ghostscript - which is highly recommended to install by GraphicsMagick. There is a link to x64 Ghostscript: https://sourceforge.net/projects/ghostscript/files/GPL%20Ghostscript/9.09/gs909w64.exe/download (I've put it here, because links from the GraphicMagick websites leads you to 32-bit only).
After that, it worked fine for me.
For some image formats (as .jpg, .png, .tif and basically all formats that require data compression), CImg will try to use an external tool to save them (such as convert from ImageMagick or gm from GraphicsMagick).
If you don't have any installed, then you won't be able to save .jpg files without having to link your code with the libjpeg library, to get a native support for JPEG read/write (then, you'll need to #define cimg_use_jpeg before #include "CImg.h", to tell the library you want to use the libjpeg features).
If you want to keep things simpler, I'd recommend to save your image using another (non-compressed) image format, as .bmp or .ppm.
These formats are handled natively by CImg and do not require to link with external libraries.
I know this question is old, but I kept getting the same error on one project and not on another and this is the only thing on Google.
To get rid of it, you must do 2 things:
Install dynamic ImageMagick libraries for your appropriate OS and architecture(32/64). Link
I was using VisualStudio, and the character set must be set to "Unicode". The error would appear again when I reverted back to Multi-Byte character set. I guess this has something to do with the way CImg handles strings and miscompares them.
I need to decompile a windows program which the source code was lost for a long time.
I am using boomerang in Windows 7 for this. However, it looks broken, gives this message and quits:
Could not open dynamic loader library Win32BinaryFile.dll (error #998)
Googling about it gives no useful results. Looking in the boomerang source code, it is apparently coming from this:
00137 hModule = LoadLibraryA(libName.c_str());
00138 if(hModule == NULL) {
00139 int err = GetLastError();
00140 fprintf( stderr, "Could not open dynamic loader library %s (error #%d)\n", libName.c_str(), err);
00141 fclose(f);
00142 return NULL;
00143 }
I.e. LoadLibraryA is failing with the status 998.
What could I do to fix that?
Edit, four hours later:
The program that I want to decompile is a work that me and a friend implemented in 2005. The source just gone in the mean time without we seeing that. Now, in 2013, when we searched it, nothing was found. In retrospect, it was probably lost in 2008 or in 2010, two occasions where my computer hardware crashed and I needed to get a new computer (and lost a lot of data with that). We had several backups scattered in several places, but after an exhaustive search, I found nothing.
I know that since boomerang is open source, I could just get its source code and hack it around. However, that sort of task is not what I originally intended to do, since the focus is just to decompile my program and I guess that I am missing something simple, since it can't load the DLL while it is clearly there.
I don't need the exact code back, just a sketch of what were the exact details of the algorithm that were implemented. Having that, I can rewrite the rest again.
I'm running a graphical program in Turbo C++ using DosBox on Windows 7 64 bit. Now, I want to use the IBM3514 graphics driver in the High resolution mode (IBM3514HI). So, I wrote the following bare bones program to test it:
#include <graphics.h>
#include <iostream.h>
void main() {
int gd = IBM3514, gm = IBM3514HI, e;
initgraph(&gd, &gm, "C:\\TC\\BGI");
if (e = graphresult()) {
cout << grapherrormsg(e);
}
cleardevice();
rectangle(100, 100, 300, 300);
cin.get();
closegraph();
restorecrtmode();
}
Now, the program compiles and runs without any errors. However, the initgraph function call doesn't initialize graphics mode. The return value of graphresult is 0. Hence, no error has occurred. Yet, the program still runs in text mode. The blinking underscore is visible and the rectangle is not drawn.
I checked my C:\TC\BGI folder and the IMB3514.BGI file exists. Thus I assume that it does load the graphics driver. Yet, I can't figure out why the program doesn't execute in graphics mode, or even throw an error. However it works perfectly fine if I use the default settings: int gd = DETECT, gm;
Any explanation as to why my program doesn't work will be greatly appreciated. Please try to provide a fix to this problem. I would really like to draw on a 1024x768 screen with 256 colors.
Under Windows your graphical adaptor is virtualized. You can't access it directly and use its specific features (unless you use DirectX/OpenGL/other strange methods). DOSBox emulates some "historical" graphical adaptors for the programs it runs (to be precise: Tandy/Hercules/CGA/EGA/VGA/VESA). You must use the VESA 2.0 driver of TC (or in general the VESA driver).
The correctly name of the driver is ibm8514.bgi - not "3514" and not "imb" or so. But like my previous speaker said, better you use another driver. The best choice is to use the egavga.bgi driver of the Turbo resp. Borland C++ or Turbo Pascal package. Then you should compile them successful.
Expect you need a special feature of this driver. Then you must check them of this effort if you need them. I think the egavga.bgi, vesa or a directly switch to the graphic mode with some special routines to make graphic should work in DOSBox, EmuDOS or in all 32-Bit-Version of Windows like Windows XP or so.
Try this code instead:
int gd = 6, gm = 0, e;
(Both variables are INTEGERS, not STRINGS)
Could anyone give me a suggestion or an example of how I would loop through the samples of CAF (Core Audio Format) file? Like taking the first 1000 samples and changing them to 0?
Something like:
for(int i=0; i < numberOfSamples; i++)
{
cafFile.sample[i] = methodThatUsesSampleValue(cafFile.sample[i]);
}
Keep in mind:
I don't need to do this live. No buffers, etc. needed.
I would like to do this in C, C++ or Objective-C.
Would like to be able to use the code on the iOS platform.
Any help appreciated!
The libsndfile C++ library is well-known and provides -among lot of other functions - a function to read AIFF-files: http://www.mega-nerd.com/libsndfile/, the lib is distributed under the "Gnu Lesser General Public License". I don't know if that is an issue.
Recently I stumbled over the amazing OpenFrameWorks library: http://www.openframeworks.cc/about And I know it compiles on MacOS and iPhone. Amongst many(!) other libs it come with an interface to rtAudio: http://www.music.mcgill.ca/~gary/rtaudio/index.html. You might want to consider also using that directly. Hope that helps.
