C++ :: Desktop Application To Utilize Camera And Scanners?
May 5, 2013
I plan on creating a desktop application that utilizes external hardware such as cameras and scanners and captures pictures and scans for use within the application. Is using straight C++ the way to go, or would a mixture between C++ and C# be beneficial? (I heard they can be used in conjunction but is it more hassle than benefit?)
Is GUI development any better in one language over the other? I am hoping to be able to choose a language with less installation requirements for the end user.
I understand that certain requirements are placed on the end users computer depending on what you are developing with (I would be using Visual Studio 2012).
I want to develop windows application using c# ,.net framework 3.5 as front and Mysql4.1 as a backed language.Now my question is i want to install this application only on server PC,so is it possible to access this application within LAN connected PC.If yes how do i build my application.or do i need to install .net framework on LAN connected PC's(or on client PC's)
I'm struggling with the pan gesture in a desktop application for my Surface Pro 2.
I simply want to pan (or "swipe" if you prefer) with two fingers, but it doesn't behave like I want it to. If I put two fingers on the screen and move them straight diagonally, I receive a series of client coordinates that are aligned in a vertical or horizontal direction. Only if I perform some circular motion, then it's suddenly possible to move diagonally and receive coordinates accordingly.
I've tried with MFC, by overriding CView::OnGesturePan. I've also tried with a sample project provided by Intel, that handles the GID_PAN message in WndProc to move a rectangle around, but with the very same result. The project can be downloaded from [URL] ... fordesktop.zip, so you can quickly reproduce the behaviour if you have a touch screen.
I first thought it had to do with the points being too close to each other. I mean, if two points lies only one pixel apart, it can only result in eight different directions. But if I modify the code to only update "m_first" when the distance between the points are greater than some minimum distance, the points still keep being projected to a horizontal or vertical line relative to the first starting point.
Using WPF and .NET 4.0 what would be the best way to utilize one panel but modify it for various options? For instance when having a basic or advanced view how would I go about changign the area to add buttons or other items most efficiently?
I'm making my view follow around my players ship, so it is always in the center, however at any angle other than 0/90/180/270 the player sprite starts shaking, more so when speed is increased and when the angle is closer to 45/135/225/315
I'm using SFML2, I would take a screenshot but it only captures one frame, which doesn't actually show it shaking.
Still working with SDL2 and c++ my map collision is messed up since I implemented my Camera.
I do understand that everything has a relative Position on the Screen, depending on the camera.
Problem No. 1: The camera is not moving as fast as the Player, despite having the absolutly same velocity (4/-4)??? How can this be O_o
Problem No. 2: My tile collision is totally messed now. Probably its because of the difference between the Player Position and the camera :/ So if you can solve Problem no. 1, Problem number 2 might work out on its own :)
How to to interface my digital camera or webcam with the c++ so that the camera can capture continuously when the camera or webcam detect a badminton shuttlecock. I am using Dev C++.
I am doing a project, which requires me to create a program which would calibrate the camera. The code is below.
#include<opencvcv.h> #include<opencvhighgui.h> #include<stdlib.h> #include<stdio.h> #include<vector> using namespace cv; int main() { int numBoards = 0;
Instead of using a Bitmap image (jpg, png, etc), I would like to use the desktop. I'm trying to scan my desktop for a pixel color using lockbits (GetPixel was way too slow.). I also do not wish to change the color of anything, I just want to loop until the pixel is found (with my getpixel method, I just put an if/then statement in the for loop). Something like:
I have a CFormView derived window which I would like to position at run time. In particular when the user clicks a button I would like to shfit the CFormView window and open up a new Dialog window so that the two do not overlap.
I have created the CFormView window and the dialog window - how to shfit the CFormView window?
I shift the Dialog window as follows in OnInitDialog: SetWindowPos(NULL, 0, 0, 0, 0, SWP_NOSIZE | SWP_NOZORDER);
write a program that will connect my laptop to my desktop unlike gotomypc.com. I want to have my desktop hooked up to a router and sends video and audio info to my laptop. At the same time my laptop will be sending it's keyboard and mouse. If there is an audio input from a microphone it will send that to the desktop. If the webcam needs to be used for something like Skype, it will send that to the desktop too. I think it would be faster for the laptop to process any flash drives, but it should be able to send that to the desktop too. Has a program like this already been created? Is C++ an optimal language to write the program in?
I have 2 database. One is on live server and the other on local desktop.
User can make changes in database offline on local desktop.
But later he wants to move his changes to live server and also get the updates done on live server by other users. How can this be accomplished? What algorithm can be applied?
What happens if I make a server application using tcp protocol and then establish connection with a client application but the server crash and then the client send data. Will the data be lost or the system will continue trying to send it?
I want to create an application that starts an application and passes input to that application. I know how to start a process using the classes in System.Diagnostics, but I don't know how to pass data to the process.
For example, and this is just an example, I would like to be able to automatically start an application that requires a username and password and automatically enter the username and password. Of course, that might open the door to security vulnerabilities, but that's not the point of the exercise.
How to implement the functionality I described? Is there a general way to go about doing this or does it depend entirely on the idiosyncrasies of the application in question?
I want to develop an application which can host multiple views of explorer (window), where as each window is totally separate from others. So that I can have multiple desktop views through my single explorer. Any built in feature in .NET ?
Is there any way to input a picture into an application? I want to make the console of my C++ program display an image across it for a short while. The picture in mind is a gif. If there is no way to make it display in the console, is there a way to make only the image and not the webpage pop up on the screen?
I am trying to replicate the Skyfall "M gets hacked" scene. But this would be useful for other purposes as well.
I am not familiar with using header files or any other files other than the .cpp file and I only use one .cpp file for all my programs.
I am using an increasing number of applications which can be serviced from a web page. These apps do not need tomcat, apache or IIS to be installed but they are able to serve out web pages on demand.
Question is how is this done? Is it just a thead polling a port, waiting for a mime message and then chucking out the content or is it something more complex than that?
i developed 2programm that the first one is in C and the second one is in c#.and now i have to send some string text from c to c#.how can i do that in c ?
I am looking at a same application in c that uses two different timing techniques. One involves the nanosleep() function which suspends thread for given nanoseconds. The other one uses a combination of gettimeofday() which returns number of microseconds since epoch as a start value. Then it uses var counter of for loop as max value. And it uses ellapsed time for each call of gettimeofday in microseconds in a do while loop to increment diff, until diff is not less than var. Why would someone choose to use this timing techinque be used instead of nanosleep?
I was wondering if there was a possible way to change my c program into an application so that i can send the application to another person and not let the other person have access to my codings?
My reasons for asking this question: For the application i want to send there are secrets that are meant to be unraveled by gameplay but i dont want people to look at the codes and know everything.
