I have a problem regarding my project. thanks for answering this :)) - C# Discussion Boards

First step of course is to look at the requirements. Don't implement the code based on what someone thinks the users will do but rather based on what the users actually do.

Second step is to look at the design. Such as the suggestion in the other posting. Which is probably likely given that people don't randomly mix up names - they are often in the same order. There are probably many other possibilities.

Third step profile the solution - actually measure where the time is being spent in the code and then try to determine ways to make those parts faster. However when doing this use REAL test data and not just random stuff.

Note that the first two items in the above are the only way you are going to achieve something that approaches what would be reasonable.

Well, first ensure that you have the best Levenshtein implementation. Your developer could post what he has in the Algorithms Forum[^].

Does the implementation calculate the full distance? Or does it stop once it exceeds the threshold?

And have a look at this old thread: Levenshtein-Distance[^].

A guide to posting questions on CodeProject[^]

I am loading a panel of dynamic questions in the panel, in the Page_Init method, to avoid situation of losing the values on postback issues. There is a linq statement that loads this dynamic panel.

The same aspx page is used in 3 step registration process.

And this dynamic questionnaire is step 3 of process. I now need to limit the questions that appear on this dynamic queationnaire, by what was entered in step 1 of questionnaire, like a radiobutton choice. How can I pass this to the Page_Init page?

Thanks!!

when i try to run the code it always return only a black screen..

here's the code..

C#

        private CvCapture VideoCapture;
        private IplImage frame;
        private IplImage imgMain;

private void btnVideo_Click(object sender, EventArgs e)
        {
            //double vidWidth, vidHeight;

            if (btnVideo.Text.Equals("Start Video"))
            {
                trainData();

                videoCapture = highgui.CvCreateCameraCapture(0);

                if (videoCapture.ptr == IntPtr.Zero)
                {
                    MessageBox.Show("Failed");
                    return;
                }

                btnVideo.Text = "Stop Video";

                //highgui.CvSetCaptureProperty(ref videoCapture, highgui.CV_CAP_PROP_FRAME_WIDTH, 640);
                //highgui.CvSetCaptureProperty(ref videoCapture, highgui.CV_CAP_PROP_FRAME_HEIGHT, 320);

                highgui.CvQueryFrame(ref videoCapture);

                //vidWidth = highgui.cvGetCaptureProperty(videoCapture, highgui.CV_CAP_PROP_FRAME_WIDTH);
                //vidHeight = highgui.cvGetCaptureProperty(videoCapture, highgui.CV_CAP_PROP_FRAME_HEIGHT);

                //CamImageBox.Width = (int)vidWidth;
                //CamImageBox.Height = (int)vidHeight;

                timerGrab.Interval = 45;
                timerFPS.Interval = 1100;
                timerGrab.Enabled = true;
                timerFPS.Enabled = true;

                hc = new HaarCascade(this);
                abs = new AbsoluteDiff(this);
            }

            else

                btnVideo.Text = "Start Video";
                timerFPS.Enabled = false;
                timerGrab.Enabled = false;

                if (videoCapture.ptr != IntPtr.Zero)
                {
                    highgui.CvReleaseCapture(ref videoCapture);
                    videoCapture.ptr = IntPtr.Zero;
                }
            }
        }

C#

private void timerGrab_Tick(object sender, EventArgs e)
{
    frame = highgui.CvQueryFrame(ref VideoCapture);

    if (frame.ptr == IntPtr.Zero)
    {
        timerGrab.Stop();
        MessageBox.Show("Invalid");
        return;
    }

    imgMain = cxcore.CvCreateImage(cxcore.CvGetSize(ref frame), 8, 3);

    cxcore.CvCopy(ref frame, ref imgMain);
    cxcore.CvFlip(ref imgMain, 0);


    pictureBox1.Image = highgui.ToBitmap(imgMain, false);

    cxcore.CvReleaseImage(ref imgMain);

}

Have you stepped through the code in the debugger to see where it is failing?

The difficult we do right away...
...the impossible takes slightly longer.

i dont know. hmm theres no failing and theres no error in the code Cry | :((

Somewhere in the code it is not giving the results you expect. Your job is to step through it and identify where.

...the impossible takes slightly longer.

uhm sir can you help me find the error in the code? i really dont know where is my error in the code. Cry | :((

Did you write that code or copy it from somewhere?

The difficult we do right away...
...the impossible takes slightly longer.

i copy it from somewhere.

would you mind in helping me sir?

I am helping you.

You need to find out how the code is supposed to work, and then step through it in the debugger to figure out where it is not working the right way.

Look up the function calls in the documentation to find out what they do.

i think i know where the code is not working..

i think in the picturebox.image = highgui.tobitmap() its not really converting.

it looks like that its not querying any frame coming from the camera..

sir there's an error when i step through the debugger..

it says that cannot evaluate expression because a native frame is on top of the call stack.

what is that sir?

I'm using the class and example "Invoking Commands With Errors Ouput" from the website below.

I need to be able to open the pipeline with elevated credentials I provide, not the credentials I use for my workstation. How can this be done?

I found this, but it causes the aspx debug web browser to crash, when I remove it, the code works fine, but of course I'm not impersonating at that point.

private void BeginImpersonation(string domain)
{

EndImpersonation();

bool success = LogonUser(

"xxx",

"xxx",

"xxx",

2,

0,

ref _userToken);

// Did it work?

if (!success) throw new Exception(string.Format("LogonUser returned error {0}", System.Runtime.InteropServices.Marshal.GetLastWin32Error()));

WindowsIdentity fakeId = new WindowsIdentity(_userToken);

_impersonationContext = fakeId.Impersonate();

//("User After Impersonation: " + WindowsIdentity.GetCurrent().Name);

}

And the exception that it throws is?

Every day, thousands of innocent plants are killed by vegetarians.

It does not throw an exception, the browser closes and the output reads

The program '[7868] WebDev.WebServer.EXE: Managed' has exited with code 1 (0x1).
The thread 0x2248 has exited with code 0 (0x0).
The program '[10108] iexplore.exe: Script program' has exited with code 0 (0x0).

I would have a check of the event log to see if any errors from the WebDev.WebServer.Exe are there.

The problem might not be with code that you have written in your page, but an error caused by the webserver from values that you have passed into it.

Good call, I'm not sure what this means yet, but this is added each time it fails.

Apparently you cannot do impersonation with some exchange commands, such as add-mailboxpermission,but can with others such as get-mailbox.
