Try making the height of the control larger. That should help show part of the combo drop down. This is not a fun exercise. To do it properly you'll need to create a dialog box, that pops up in the right place, determining if should drop up or down. And then the hard part. Working out when it loses focus.

dear friends,
I need to get picture of each box on the conveyor band while they are on the move. I can get video stream of conveyor (of course) but I don't know how to get pictures of them.
I believe algorithm has to separate each object with the distance among them and when new object come into sight, should take the picture. assuming that the belt (means background of image) is black, algorithm can process image by contrast. but I need to get each objects picture ONCE. box sizes are different so I cannot use belt speed, timings, etc. I need to "understand" which object is where on the video stream.
any ideas please ?

Hi!
How to print a BMP graphic in Zebra TLP2844, using VB6?
Thanks

Hello All,
I want to know how to use the color rotate function to pro-grammatically select a different color for each of the "curves" and using a "list" I add to a graph for e.g.: by use of a button command.
Thanks in advance,
Nikhil

There is a TextBox in my Project. It takes Math expression as Input.
eg., sin(Cos(10))
How to Parse for the functions and perform the trig calculations.

there are a lot of articles on parsing and evaluating expressions here at CP.
Here is one (not VB.NET!)[^] of them, however you'll have to search for one that suits your needs.
From your recent questions, I'm not sure you're up to it already.

you have a couple of options
1. Open Forms collection
my.application.openforms collection[^]
but this assumes the form is already loaded!
2. or this code snippet
Public Function GetForm(ByVal Formname As String) As Form
Dim t As Type = Type.GetType(Formname)
If t Is Nothing Then
Dim Fullname As String = Application.ProductName & "." & Formname
t = Type.GetType(Fullname, True, True)
End If
Return CType(Activator.CreateInstance(t), Form)
End Function

In VB 2010 the TextBox displays negative sign after the number. It displays -1234 as 1234-. I am coding a calculator and it has a +/- button.
code is :
if plusminus button is clicked
ReadOut.Text = Convet.ToString(Convert.ToDouble(ReadOut.Text) * (-1))
|
|
|
|
|
Use this
ReadOut.Text = (CDbl(ReadOut.Text) * -1).ToString

The codes below doesn't solve my Problem
ReadOut.Text = Convet.ToString(Convert.ToDouble(ReadOut.Text) * (-1))
ReadOut.Text = (CDbl(ReadOut.Text) * -1).ToString

Hello !
Always i have used this code to query from entity framework
dim query=From t1 in context.mytable where conditions
select t
Now i need to declare query variable before using.this is my code
----------------------------------------------------
Dim query1 as ???????
Dim list1 as ???????
query1=From t1 in context.mytable where <conditions>
select t
list1=From t1 in query1.ToList where <conditions2>
select t1
---------------------------------------------------
What are the types that should i use on Dim .....?

You have many ways to consume the results but, which is best depends on what you are after doing with the results.
I would look into
1.
dim Query as IEnumerable(of t)
Ienumerable(of t)[^]
2.
dim Query as List(of t)
List(of t)[^]
3.
dim Query
But this one you already know about

thank tou , but in my code i have :

Dim list1 as ???????
query1=From t1 in context.mytable where conditions1
select t
list1=From t1 in query1.ToList where conditions2
select t1
which of your variants should i use for query1 and list1 ???
thank you !

without knowing what you are going to do with the results. I would start with using the list(of t) where t is your table name.
I.E
dim Query1 = (From t1 in context.mytable where conditions1 select t)
dim List1 as list(of mytable) = (from t1 in Query1 where conditions2 select t1).toList

Dim query as ????????
and after to use : query1=From t1 in ......
so how i can declare Query1 ?
Thank you.
