With these it helps It returns an array of DataRow that match the selection criteria expressed by the first parameter of the Select method
code :
DataRow[] dr = objds.Tables[0].Select("ProcessName = '" + tnProcName.Text + "'");
foreach(DataRow r in dr)
{
   string procName = r["ProcessName"].ToString();
   treeView1.Nodes.Add(procName);

}
DataTable.Select(); // return all (same as dataTable.Rows)
DataTable.Select(filter); //The above one
DataTable.Select(filter, sort) //Filtered and/or sorted
DataTable.Select(filter, sort, rowstate) // Filtered and/or sorted and/or in a particular state
DataRow[] dr = objds.Tables[0].Select("ProcessName = '" + 
               tnProcName.Text.Replace("'", "''") + "'");

Does that help Such allocation schemes have been used everywhere from the early Unix file system to Python's internal list allocation.
Code on!

To fix this issue I have two rating/votes tables. One for user votes and stats and another for external votes. The external votes table always have data because it has a DEAFULT = 0, but the users votes only contains data if any user have voted for that specific ID.
code :
SELECT  ratings_stats.votes, 
        ratings_stats.total_value,
        ratings_stats.view, 
        ratings_stats.fav, 
        ratings_stats.wish,
        ratings_external.votes, 
        ratings_external.total_value
FROM  ratings_external
LEFT JOIN ratings_stats ON ratings_stats.imdbID = ratings_external.imdbID
WHERE ratings_external.imdbID = ?
LIMIT 1

wish helps you I was looking for Partial Response.
RESTful API Design: can your API give developers just the information they need? explains it all and gives examples from LinkedIn, Facebook, and Google. Google and Facebook both have similar approaches. Here's how Lie Ryan's example would look using Google's approach:
code :
url?fields=status,result(color,price)
LibGDX - InputProcessor - if user draggs finger from button which represents moving on X, to button which represents mov

I think the issue was by ths following , I would probably go for something like this in the player class update method itself
code :
//Declare velocity on top so you just have to change this to fine tune speed.
float velocity = 10;

if (Gdx.input.isTouched()) //isTouched should register as long as a screen is touched, you can use pointers for multiple fingers.
{
    if (touch within button) //just use Gdx.input.getX / Gdx.input.getY
    {
        position.X += velocity * Gdx.graphics.getDeltaTime();
    {
     //do for each button
}

will be helpful for those in need In Code A, this it is the email "yole@example.com", and in Code B, this it is every single char 'a', 'b', '1', 'c' of "ab1c", why? , These two methods:
code :
email?.let { sendEmailTo(it) }  //This it is the email "yole@example.com"
println("ab1c".filter { it in 'a'..'z' })  //This it is char  'a', 'b,' '1','c' of "ab1c"
email?.let(fun (string: String) {
    sendEmailTo(string)
})

println("ab1c".filter(fun (char: Char): Boolean {
    return char in 'a'..'z'
}))
