That's interesting, but what are you trying to accomplish? Without that we can't help you.

You could try my Code Snippet Manager[^], I'm sure it could be adapted to VB.NET without too much difficulty.

That dont work ... (Just Create Notify Icon and ContextMenu , nothing else...)
Please help more than it... (if possible...)
thank you

What "don't work"? If you wish for help with your problems then it's about time you made a greater effort to explain them in proper technical detail.

Maybe if you bothered to read the article you would find out how it worked and how it might be able to help you. You really need to make a bit more of an effort for yourself and not expect to be spoon fed for the rest of your life.

Great link. Thanks Richard.
Why is common sense not common?
Never argue with an idiot. They will drag you down to their level where they are an expert.
Sometimes it takes a lot of work to be lazy

I wanted to know if I can use Aforge library for YUV display in a GUI that I want to create, I just wanted to know if I can use Aforge for this?,
I have used OpenCV for this, But that is not customizable. Thus exploring other options

how to type in a datagridview textbox column and find in a listbox like a tally finds in vb.net

Not everyone is aware of what Tally is or how it works. Please be specific in what you are trying to achieve and where are you stuck.

My ticketing system has reached a point where the installations will need to communicate with the office. I cannot guarantee constant connectivity.
I am thinking of SOAP with Web Services. It appears easier to follow than TCP networking and in my limited knowledge perhaps better suits my needs.
Traffic will not be constant and it will function more as a notification device telling the office what transactions have taken place onboard, and the office will then notify other installations of tickets sold elsewhere.
What should I be looking out for?

Hello
I have a class :
cls_Communication_base
which has a private variable
Private p_Descr as String = nothing
and a public property
public Overrides property [Descr]() as String
get
return me.p_Descr
end get
set (ByVal value As String)
me.p_Descr = value
end set
end property
I have some load method, which loads data
from a data table and assigns the value from
the datarow to the property
row is a datarow from a datatable with 47000 Records
public overrides sub fillDataRow(byval row as system.data.datarow,byval bolBuffer as boolean)
...
If (Not row.isNull(5)) Then
' this line is too slow, really!!!!!!!!!!
me.Descr = row(5).tostring()
End If
....
end sub
Like said. Everything is ok in terms of speed. Only the line assigning the row value to the string property is really slow.
OK. I am skipping a lot of lines here to make the example easy. But, Without this line assigning the value to the property (but creating 47000 instances of my class and doing everything like querying the database takes Zero Seconds). Just including this one line and the whole thing needs 72 seconds
So, I guess there is something wrong in my way assigning strings to a property
Is there a better way assigning values to a string property?
Many thanks for helping

Not sure that there's any other way let alone a better one!

There is no other way to do this.
Since creating a string involves memory allocation and filling in of data, remember, you're doing this 47,000 times!
If your case, you're also looking up an array item then calling ToString() on that object. You're doing a lot of stuff to create a string, so the trick is to have the string already created for you, like in an XML document or something...

I'd bet the problem is not in the string assignment but in the call to tostring() . Strings are objects with reference semantics. They are assigned by copying an address (think "pointer"). This is not going to be expensive. (Well, for a property it calls the setter method which simply does the simple assignment, and a good compiler will optimize this to eliminate the call overhead. You are doing timing in Release mode, not Debug, right?)
This can be verified by removing the assignment but keeping row(5).tostring() and ignoring the returned string.
The real questions are:
What type of object does row(5) return?
How expensive is it's tostring() implementation?

I am currently learning EF and I am coding a Windows app as part of the learning process.
Given this code fragment:
using (var context = new MovieList_EFEntities())
{
string esql = "select value m from Movies as m Where m.MovieId = " + Convert.ToInt32(movieId) + "";
var Movies = context.CreateQuery< Movie>(esql);
foreach (var movie in Movies)
{
movie.Name = tbTitle.Text;
context.SaveChanges();
}
}
SaveChanges throws an exception - New transaction not allowed.
The Movie entity maps to the equivalent database table composed of 2 fields, the PK (identity) and the Name field. I want to change the Name. Why is the above not permitted?
As a workaround, I created a Movie object with the 2 field values assigned. I did not get the desired effect. My db record was not updated, rather, EF inserted a new record. I will figure this out eventually. Was hoping someone can help me out before I do.
Thank-you.

You should try to get the movie from the context using LINQ.
using var context = new MovieList_EFEntities())
{
int id = Convert.ToInt32(movieId);
Movie mov = context.Movies.SingleOrDefault(m => m.MovieId == id);
if (mov != null)
{
mov.Name = tbTitle.Text;
}
else
{
}
context.SaveChanges();
} Hope it helps, good luck!
It's an OO world.
public class Naerling : Lazy<Person>{
public void DoWork(){ throw new NotImplementedException(); }
}
