c++ - Program does not proceed - OpenCV related -

-

I got OpenCV to work at the end, but I had to face a problem where my program does not grow ( No results). The result of the program should be an image in a new window. Snippet: #include & lt; Opencv2 / core / core.hpp & gt; #include & lt; Opencv2 / highgui / highgui.hpp & gt; # Include & lt; Iostream & gt; Using namespace cv; using namespace std; Int main (int argc, char ** argv) {if (argc! = 2) {cout & lt; & Lt; "Usage: display_image imageToLoadAndDisplay" & lt; & Lt; Endl; Return -1; } Mat image; Image = imed (RGR [1], IMRADADOLOR); // Read the file (! Image.data) // Check for invalid input {cout & lt; & Lt; "Image could not be opened or found" & lt; & Lt; Std :: endl; Return -1; } Named window ("display window", WINDOW_AUTOSIZE); // Create a window for display imshow ("display window", image); // Show our image inside waitKey (0); // Wait for a keystroke in window return 0; }

Point is a program that successfully creates, but when I debug it, nothing happens. I tried to get started without debugging (ctrl + F5, I'm using MSVisual2012) and that has been raised: Enter image details here

How can I fix this? Is it linked to a bad library?

Output "Usage: Display_Image ImageTolled Endspeplay", which means the file does not get the name of the program Can:

  1. image = imread ("C: \ myfile.jpg", IMREAD_COLOR); (and delete the previous lines)

  2. Open the terminal, cd in the executable dior and yourprogram to run Exe myfile.jpg

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i

I am trying to create Java web framework (and learning), and on the basis of 'Code Generator In the process of making the material view of the database in the process of development, I stumbled into a difficulty, which I do not know how to solve it.
