how to remove duplicate matches in MatchCollection
Web Development

I'm using C# .NET, WinForms 2.0

In my MatchCollection, I get matches of the same thing. Like this:

string text = @"match match match";
Regex R = new Regex("match");
MatchCollection M = R.Matches(text);

So my question is, how to remove duplicate matches in the fastest way possible? Assume duplicate here means that the match contains the exact same string


Upload to Artifactory using Java client
Web Development

I use Artifactory Java client, and cant upload file to Artifactory. My code is very simple, taken from Artifactory Java Client test folder:

artifactoryClient = ArtifactoryClient.create("localhost:8081",
"admin", "admin");
InputStream content = new ByteArrayInputStream("I want to test my
upload!".getBytes());
UploadableArtifact apAtrifact =  artifactoryClient.repository("ext-snap

Exact comparison between two numbers with ZEROFILL
Web Development

I have a PHP script where I want to compare two numbers.

$usernumber = $_POST['usernumber'];

$sql = "SELECT password, isadmin, disabled FROM user WHERE usernumber = " .
$usernumber .";";

Everything is working fine but there is one more or less cosmetic problem.

The usernumber is saved as a DECIMAL(5,0) with ZEROFILL. If I compare

How to test reports?
Web Development

We are developing a Rails app, that has quite a few pages with data reports. A typical reporting page is based on a relatively big SQL query, usually involving 5–8 table joins.

The cornerstone question we've stumbled upon is – writing integration tests reports pages. A common integration test of ours looks like this:

  1. creating a bunch of records in the DB via

SQLite Java Android no such table, program crashes
Web Development

ORB/Bruteforce Hamming Good Matches Inaccurate
Web Development

I have this android program that would take a source images which will be matched with a template image. Using ORB, I was able to detect keypoints and extract descriptors as well. For matching, I used Brute-force hamming as suggested by some OpenCV tutorials that would fit for ORB descriptors. Based on the initial results, Brute-force hamming was able to match descriptors between a source image


Avoid multiple similar foreach - C#
Web Development

I apologize if I'm posting into the wrong community, I'm quite new here.

I have multiple methods using the same foreach loop, changing only the inner method I call:

    public void CalculationMethod1()
    {
        foreach (Order order in ordersList)
        {
            foreach (Detail obj_detail in order.Details)
            {
                CalculateDiscount(obj_de

fprintf and fwrite (written bytes to fp)
Web Development

I have question about fprintf and fwrite. How many bytes are written when this code runs (assuming fp has been correctly set up).

int i = 10000;

fprintf(fp,"%d",i);

fwrite(fp,sizeof(int),1,&i);

When I checked then 5 bytes and 9 bytes respectively. Maybe I am wrong. I thought it is 4 bytes since int. Can someone explain please??? Thanks.
