@badrepent Thanks for the tutorial, however i get `imageBoxCapturedFrame` does not exist erroe. can you help me out regarding this error?

[badrepent]

@Yashu808

It simply means that there's some error with emgu imageBox control. It could depend on non correct loading of emgu dll's. Take a look at references section of my project and check that all dll's does not contain a yellow triangle. You should also take a look at emgu website where there's a tutorial on using and loading imagebox control.

@badrepent

hello! thank you for the code, i downloaded and tried it,but there was that sticky cvInvoke error again,

if you'd kindly add opencv_core220.dll and opencv_highgui220.dll to your debug folder, then the most downloaders wont have anymore trouble running the application with Cvinvoke error :)

[badrepent]

@MrShybul

You should install visual c++ runtime (x86 or x64 it depends on your machine). Follow emgu wiki installation issues and you'll be able to run the code...

[MrShybul]

@badrepent i've install the runtime..but my prob occur when pop up window asking for capture.cs file in C:\Users\Luca\Desktop\EmguCV\E­mgu.CV\Capture\Capture.cs.

I've install libemgucv-windows-x86-2.2.1.11­50..and locate the capture.cs file...

but..still cannot run...

help me pls..

[badrepent]

@MrShybul

Are you able to run examples that comes with your libemgucv-windows-x86-2.2.1.11­­50 installation.

Right now you are simply debugging my code that comes with precompiled dll so debugger is not able to find

source code for Capture.cs class. Your problem does not concern my code...

[MrShybul]

@badrepent yes..i can run all example in emucv lib.

yes, i believe that this prob is not bcoz of ur code..

so, how to run this code..help..help
