These are my directories:

I have been creating instance to that COM exe (child exe) and at the end of the function i am releasing that object (myinfo->release).i want to create single instance for it and i want to use them in different .cpp files and finally i want to kill the child exe.

int number , a;
cout<<"enter en integer number";
cin>>number;
cout<<"add 600 to the number"
cin>>a=number+600;

C++ :: Undefined Definitions When Try To Compile A Single File (GCC)
Jul 4, 2013When I try to compile a single file with GCC (I'm using Code::Blocks as my IDE if that is relevant) it gives me a bunch of undefined reference errors. Well, of course they are undefined since I haven't linked anything yet, but why is GCC complaining at compiling time?
The problem is that when I try to link and compile the project in one go I don't get any errors. The references in question are from the GLEW library if that is relevant.
srccharrenderer.o:charrenderer.cpp|| undefined reference to `_imp____glewDeleteBuffers'|
srccharrenderer.o:charrenderer.cpp|| undefined reference to `_imp____glewDeleteBuffers'|
srccharrenderer.o:charrenderer.cpp|| undefined reference to `glEnableClientState@4'|
srccharrenderer.o:charrenderer.cpp|| undefined reference to `_imp____glewBindBuffer'|
srccharrenderer.o:charrenderer.cpp|| undefined reference to `glVertexPointer@16'|

C++ :: Calling A Script From Makefile
May 18, 2013I would like to call a script from a makfile to glean some information about the OS. What I more or less need is the OS name and version (CentOS-5.9, OPENSUSE-12.2, Cygwin, etc). I think I can get the rest of what I need from uname. The OS name and version doesn't seem to reside in any consistent place over the various Linux flavors. I also need to get the version of the gnu c compiler, since I think that may also require a bit more involved scripting than I would like to try out of make.
The main question is weather I can call a script out of make and have it return a value for a variable.
Something like,
OS := $(shell ./script_name)
C++ :: Makefile Options To Compile For 64 Bit

C++ :: Reading Two Words Into Single Char Array From Text File
Sep 15, 2014I am trying to read in player names (ex: first last) from a text file into the people[].name data struct. I can successfully read in my card file, but I cannot get this to work. I get a seg fault. I believe this is because nothing is actually being read in for my while loops. I can't use std::strings so these must be c-style strings aka char arrays.

C :: Create File To Write Text And Read Back The File Content
Mar 15, 2013The Objective Of This Program Is To Create A File To Write Text And Read Back The File Content. To Do That I Have Made Two Function writeFile() To Write And readFile() To Read.The readFile() function works just fine but writeFile() doesn't.
How writeFile() function Works? when writeFile() function Execute It Takes Characters User Type And When Hit Enter(ASC|| 10) It Ask "More?(Y/N)" That Means What User Want? Want To Go Next Line Or End Input?
If "Y" Than Inputs Are Taken From Next Line Else Input Ends.
But The Problem Is When Program Encounters ch==10 It Shows "More?(Y/N)" And Takes Input In cmd variable.If cmd=='Y' I Mean More From Next Line Than It Should Execute Scanf Again To Take ch I Mean User Input.But Its Not!!! Its Always Showing "More?(Y/N)" Again And Again Like A Loop.
Code:
#include <stdio.h>
void writeFile(void);
void readFile(void);
int main(){

C++ :: Create Save File For A Game That Is Not A Separate File?
Oct 10, 2014How do you create a save file for a game, that is not a separate file? Specifically I am using code::blocks and sfml 2.1 to make a game and it saves to a text file at the moment. My problem is that it is very easy to modify the text file, and it is annoying to have to copy and paste several files if you want to use a copy of the game. I have a feeling that it may be to do with resource files, but I'm not exactly sure how to get these to work or whether you can modify them dynamically.

C :: How To Create A Program That Take AVI File
Jan 26, 2015I want to create a program that would take an AVI file, alter each frame (ex: change contrast, invert colors, etc.) and dump a new AVI. I've wrote a simple program for this experiment that loads up the header information from the video and dumps it. It also dumps a list of the frame data chunks within the 'movi' chunk.
The info I've gathered from coding this:
1. The recommended buffer size for each type of stream (vids, auds, etc.) is the size of the largest frame of corresponding type, plus 1 or two extra bytes.
2. numFrames in main header is the total number of frames for all types of data (video,audio,etc.) The 'length' value within stream header of type 'vids' is the number of video frames. The sizeImage value within BITMAPINFOHEADER is 921600 (==640*480*3) and the specification states that, quoth, "This can be set to 0 for uncompressed RGB bitmaps."
3. This video uses DIVX encoding.
Now my problem is this: How do I get the data within each video frame in a simple BMP like format? Even the uncompressed frames (with chunk id 'nndb') have variable sizes...let alone the compressed ones.
Information about a software that converts AVIs to a format with fixed sized uncompressed frames. Or at least some information about the frame decompression techniques.
Here's a dump made by the program for a 9 sec, 640x480 video I recorded from Pokemon. (Without the frame dump that is, it'd have made the post too long.)
Code:
AviMainHeader
-------------
size = 56
usecPerFrame = 66666
maxBytesPerSec = 7680000
padSize = 0
flags = 0x00000810
numFrames = 162
initialFrames = 0
numStreams = 2
