C# :: How To Show A Frame Of Gif
Jan 10, 2015
I want to show a frame of a gif image. I searched and found that the following code should work, but it doesn't work. it detects the number of frames correctly but it shows the whole frames of gif instead of the specified frame.
Image[] frames = new Image[36];
Image GG = Image.FromFile(@"C:UsersAdministratorTEST C#TEST2frame2chef.gif");
FrameDimension dimension = new FrameDimension(GG.FrameDimensionsList[0]);
// Number of frames
int frameCount = GG.GetFrameCount(dimension);
label1.Text = frameCount.ToString();
// Return an Image at a certain index
GG.SelectActiveFrame(dimension, 1);
frames[1] = ((Image)GG.Clone());
pictureBox1.Image = frames[1];

Code:
/* some useful headers */
#include <stdio.h>
#include <fcntl.h>
#include <errno.h>
//my headers
#include <iostream>
#include <fstream>
#include <string>
#include <cstring>
#include <vector>
[XCode] .....
The bit that's giving me issues is the "calculatedetails" function, where an mp3 file is opened in binary and then an array of chars is filled with the binary data.
The problem I'm having is that I want to be able to read the constituent bits of the characters in, so that I can find the mp3 frame headers (12 1's in succession)
I'm aware that the section I've added in to perform this is incorrect.

I m trying to place an image on the colour frame of the Kinect live video. I m able to overlay the image using alpha blending mechanism.
The image used is a bitmap image of dimension 128*128.
The Kinect has a resolution of 640*480.
IDE used is Visual studio 2010 and I m developing using c++.
The Kinect has a render target whose size is taken as 640*480 so that it stretches for the complete window. So when I try to overlay the image it appears 5 times because of this stretching.
If I increase the image size to 640*128 i get a single image that is stretched horizontally across the window with dimension 640*480.
I have created a function that will create a render target with bitmap properties and size equal to 640*480. This is used to store the data from the Kinect, frame by frame, and draw it on to the screen
So I think when I overlay the image, it gets replicated 5 times to meet the render target size.By default the image is placed at the left top position.
My doubts are
- How can I use different functions to specify the size of render target for Kinect as 640*480 and the size of render target for bitmap image as 128*128.
- How to I give overlay or place the image on the live video at a specific location.

what I'm trying to do is output a certain string depending on the color I see in the video feed. For right now, what I've done is threshold the feed so that everything above a certain brightness shows up as Red. Now I want to have something that says if there's any red in the feed, then I output a "1" to a text box on my user interface that's showing the feed. If there is no red, then I output a "0" to the text box.
I'm using Emgu CV C ++ with VS2010.
This is the code I have so far that isn't working correctly, it's giving me a compiler error.
cvConvertScaleAbs(frameFromCamera->Ptr.ToPointer(),frameDisplay->Ptr.ToPointer(),double(1)/16,0);
cvCvtColor(frameDisplay->Ptr.ToPointer(),frameColorDisplay->Ptr.ToPointer(),CV_GRAY2BGR);
cvThreshold(frameDisplay->Ptr.ToPointer(),maskSaturated->Ptr.ToPointer(),200,255,CV_THRESH_BINARY);
[Code] .....
and the error it's giving me
BAOTFISInterface.cpp(1010): error C2664: 'Emgu::CV::Image<TColor,TDepth> ^Emgu::CV::Image<TColor,TDepth>::InRange(Emgu::CV::Image<TColor,TDepth>
^,Emgu::CV::Image<TColor,TDepth> ^)' : cannot convert parameter 1 from 'Emgu::CV::Structure::Bgr *' to 'Emgu::CV::Image<TColor,TDepth> ^'
[Code] .....
Build FAILED.

A program is a set of all subsets of this part of the show. Users can enter a number., For example, if n = 2 the output looks like this:
{}
{1}
{2}
{1,2}
or for n=3 we have:
{}
{1}
{2}
{3}
{1,2}
{1,3}
{2,3}
{1,2,3}
meantime this program should be solved with tow way. recursive function and Non-recursive.Can also be used in solving the problem of bitwise operations.

I am working from my "ansi c" book by steven lawlor, page 73 program 2. write a program that accepts two numbers from the keyboard and prints the following information.
variables
first
second
execution
First number ? 7
Second number ? 2
the second goes into the first 3 times
with a remainder of 1.
the quotient is 3.5.
Code:
#include <stdio.h>
main() {
int first, second;
scanf(" %1i %1i", &first, &second);
printf("First number ? %1i
[Code] ....
//I included this as I had some error message come up
// before, not sure if this is correct though?
} it shows what is expected but I cant get the 3.5.
I have tried %f and variations of width/precision but still not luck. Also, when I click on the application and put in the variables I press enter, the program executes and disappears so I cant see the result. how do I get the program to stay up until I want to get rid of it?

I have been given an assignment which I have big troubles with. The assignment is:
"If I ask you “When is the weekday of the 2nd of August in 1429?”, you can answer immediately with your program to my question.
The initial value for the 1st of January in (the year) 1 will be sought by inducing, for example the crucifixion of Jesus is said to be held on Friday, the 3rd of April, AD 33."
How can I solve this?

I would like to know if there's a way to show at least two numbers in the output instead of just one. For example: instead of showing 4 it shows 04. Its for a console application.

As you can see I will have the Name and total right next to eachother.. Problem is I dont want to make a million MySQLCommands for each ID.. Is there a Way I can list all data in each label?
For instance the Select from Text will show all the text from each different ID
and the Select from STOCK-USED as total will show all the total for each ID
Instead of having to list them individually.
Even if I leave it to this
"Select text FROM `parts`";
It selects the 2nd ID in my database and displays its text.. Forgets about the first one completely ...

I created a simple calculator in Win App. When I played it, the form is displayed blank. Not a single control is shown.
The only thing I've done differently is adding a Coded UI Test in my test project. This is the first time I'm going to try to add a coded UI test so I wonder if that's the cause for this.

I have a main WinForm that I want to press a hotkey and show and hide the form. I can press Insert and hide the form and I see its icon in my Win7 task bar but when I press Insert again it doesn't show. Is my coding logic wrong to make it work? Maybe when its hidden the Insert key isn't being 'seen'? Although the code I am using I got somewhere on the internet that says it will work at the app level.
virtual bool PreFilterMessage(Message% m) {
// Detect key down messages.
if (m.Msg == WM_KEYDOWN) {
Keys keyCode = (Keys)((int)m.WParam) & Keys::KeyCode;
