Visual C++ :: Can Only Make Video With 255 Frames
May 4, 2015
I have code (found long time ago, ~2001) to make videos from OpenGL rendering in my view class. In my OnDraw() function I call the function SaveAsAvi(). This works as intended until I have 255 frames in the movie I am trying to make. After that, Windows Media Player claims it cannot play the file. VirtualDub claims the avi contains Palette Changes and shows the correct number of frames (>255) but all frames past 255 are the same and equal to the last frame.
Memory overflow? Need to free m_pixels sometime somewhere?
Code:
void C***View::SaveAsAvi() {
C***Doc* pDoc = GetDocument();
if (pDoc->m_avi_status == -1)// initialize AVI stuff {
KillTimer(1);
// allocate space for the pixel info
[Code] ....

I have a code which is a set of rgb frames to be displayed at 25 fps to make it look like a video. While I createWindow invalidate and update it based on a timer, the video plays fine, but the buttons of Play, Pause etc hangs during the time video is playing.?

I am using DirectShow to play/pause/stop a video file. I am having a slider control which increments with the playing video. I have done some calculation to find the exact step to forward or backward the video.
On dragging the slider to any position, video forwards/backwards to the new position, but slider doesn't get increment. Say I drag the slider from 10 to 50, video goes to the new position, but on releasing the capture slider again jumps back to the previous position from where it was dragged.

I would like to know in which way is the best to make ActiveX control for video. ActiveX control will need at least show picture and be able to go back in past, change resulation of picture and similar. How complex it is to do something like that? Is MFC best way to make it? Is there somewhere similar code?

I am working on a project in which we capture a video using DirectShow samples. I want to know whether it is possible to capture a video with No noise, No interference etc. in other words, we want to capture High Quality (HD) video using DirectShow.
Is there any sample defined in DirectShow using which we can capture HD video.

I am working on a project in which I use DirectShow to Play / Pause / Stop the video. I am using slider bar to show the progress of the video. As the video starts playing, the slider bar moves in proportion to the video duration. Now when user moves/drags the slider bar to a new position, I want to forward the video in equivalent proportion.
Say if video duration is 50 seconds and max range of the slider bar is set to 100. slider will 2 steps for 1 second of video progress. Now if user drags the slider to 60 while video is playing, I want to increment/forward the video. if user moves the slider backward, video should move backward.
I have done with the slider moving along with the video and when user drags the slider. How to set the new position of the video, so that the video starts playing from that point.

I tried to initialize the frames variable but when I go to debug it, it just gives me 30 errors compared to the one error when I don't initialize the frames variable.
#include "Gfx.h" // general gfx lib I made for SDL
#include "Input.h"
#include "General.h"
#include "Sprite.h"
#define screenw 620
#define screenh 480

//int mousex; int mousey; int mouseon = 0;
//int red = 0; int green = 0; int blue = 0;

I am fairly new to the topic of the ethernet and the data link layer and I am trying to write a C program which allows the sending and receiving of ethernet frames.
I am trying to have my program send the ethernet frame to myself, so the program will have the same source and destination mac addresses.
The program that I'm using is a modified version of the code from [URL] ....
I keep having trouble with the recvfrom() function, it seems to just be blocking and the program doesn't terminate. From the code, I am trying send the ethernet frame and have the recvfrom() function be able to retrieve the frame and store it in a buffer. But because recvfrom() function is just blocking, it seems to me that the sendto() function was not able to successfully send the frame.
Here is my code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <sys/socket.h> /* Must precede if*.h */
#include <linux/if.h>
#include <linux/if_ether.h>
[Code] ....
This is on a linux machine ....

I am trying to make an add-on to IE. This add-on doesn't have any tool bar or any UI.
I am just taking the details of currently loaded HTML page. Basically it is for manipulating one dialog box. I want to get access to the DOM COM interfaces of the dialog box.
Since it doesn't have any button I didn't impliment IOleCommandTarget. I implemented only IObjectWithSIte.
My RGS file contain following in addition to my COM related entries
HKLM
{
NoRemove SOFTWARE
{
NoRemove Microsoft
{
[Code]...
But I couldn't see my add-on working or even not loading to IE.

I'm developing a software for Windows using MSVC 2010. My employer sent me 2 png files: 16x16 and 32x32 for the icons.
What I would like to do is to use them as a MSVC icon resource and don't use any code hacks. In the past all I had was an ico file and I just included it in the resource (rc) file for Visual Studio and that was it.
Now my question is: how do I make one ico file out of those 2 png files that will be accepted by MSVC? Is there a tool (preferably free) for it or some online service?

Here is my code for a simple game. paste it and try it.
#include <iostream>
#include <string>
#include <ctime>
#include <cstdlib>
using namespace std;
int main (void) {
stringg[4],
[code]...
What they do (enter 4 actions)?
";
for (int ai = 0; ai < 4; ai++)
getline(cin, a[ai]);
cout << "
Where is happening (enter 4 locations)?
";
for (int li = 0; li < 4; li++)
getline(cin, l[li]);
for (int c = 0; c < 4; c++)
cout << g[rand() % 4] << " and " << b[rand() % 4] << " are " << a[rand() % 4] << " from a " << l[rand() % 4] << endl;
return (0);
}
At the end in the 4 lines some of the names, actions and locations repeat. How do I make them to not repeat and use every name that you will enter? do I need random_shuffle? How can I integrate it in my code?

I know how to define a shape (here, a rectangle) and attach it to a window in C++ as follows:
Code:
#include <Simple_window.h>
void cir() { Circle c(Point(100,100),50); }
int main() {
Simple_window win(Point(100,100),600,400, "test");
[Code] ....
But how to define a shape (say a circle by that cir() function which is) outside of the main() function that is how to create a circle inside of the cir() function and it returns that circle when I called it in my main() function so that I can attach it on the window win to be visible?

I'm working on a project which uses gtk+ and gtkmm. We use them in preference to MFC because the program needs to be cross-platform. For quite a long time, customers on OS-X and Linux have sometimes complained that the program would crash during shutdown but the Windows version (which I work on) never seemed to suffer. However, I'm now transferring my build environment to a new PC and I'm noticing the same shutdown crashes. It's a bit complicated so let me start with a small example:-
Code:
namespace Whatever {
class B {
public:
virtual ~B();
private:
int bb;
[Code] ....
Suppose I run the above program. When it stops at breakpoint #1 I make a note of the value of pA. Eventually the program reaches breakpoints #2 and #3. At each point my this pointer is exactly the same number. If the value of pA was 0x03604fb0, my this pointer is identical at both stages.
Now let's consider the real example:-
Code:
namespace Gtk {
class Widget {
public:
virtual ~Widget() {}
[Code] .....
Suppose I run the real example. At breakpoint #1 the value of pW is 0x03604fb0. But by the time I reach breakpoint #2 my this point is slightly different:- 0x03604fcc. It doesn't seem right to me and I'm wondering if it might be contributing to our shutdown crashes.

I'm trying to remake my Windows screensaver written with C++ and WinAPIs to work on multiple monitors. I found this article that gives the basics. But when I implement it in my own code, I get a weird result. Take a look at this code:
Code:
case WM_PAINT: {
PAINTSTRUCT ps = {0};
HDC hdcE = BeginPaint(hWnd, &ps );
EnumDisplayMonitors(hdcE, NULL, MyPaintEnumProc, 0);
EndPaint(hWnd, &ps);
[code]....
Painting always works on a primary monitor. But when I paint to the secondary monitor, I can only paint directly to its DC. When I use double-buffering technique (with DIRECT_PAINT pre-processor directive commented out) I only get a black screen on a secondary monitor when it should've been red.
First one with direct painting that works:
and then the one that doesn't, with double-buffering technique:

My assignment is to create a C++ Program to find the sine of a number without any library other than iostream by using Taylor Series:
sin (x) = (x/1!) - (x^3/3!) + (x^5/5!) - (x^7/7!) + (x^9/9!) ...... (x^n/n!).
Here is what i have done till now:
#include <iostream>
double fact (int f); //declaration of factorial function
double power(double x, int y); //declaration of power function
double sin(int x); //declaration of sine function
//double cos(int x); //declaration of cosine function

I have been working with video files and my task is open a video file, get it copied into another file and then changing into binary format. after getting few bits inverted, changing back it into ascii formats. Original video contains normal and extended ascii codes. Unfortunately, i got stuck at first step, whole video file is not being copied. i have written a piece of code that copies the whole word/ any text file but the video file is not fully copied as just 5KB out of 119,659 KB are copied.
Code: #include "stdafx.h"
int _tmain(int argc, _TCHAR* argv[]) {
FILE *fp1,*fp2;
char c;
fp1 = fopen( "sample.mpg", "r") ;
fp2 = fopen("result.txt","w");
