As Dave allready has written ...
But there is another possibility :
You create your own (customized) AnalogueLabel which derives from Label and has a Property 'Value' which type is for example single (or double).
If a legal value is assigned to this Property you can assign it to the Text-Property with the rerquired formatting :
Public Class AnalogueLabel
Inherits Label
Property Value As Single
Get
Return my_Value
End Get
Set(value As Single)
my_Value = value
Me.Text = my_Value.ToString("F3")
End Set
End Property
Private my_Value As Single = 0.0
End Class

I have a string...
<pre><add name="ConDB" connectionString="‘Ú·ÐŽÇáäޯΟ£‘ ª~«q œª¤ªµºÒÖÛÂÞ™Ú·ÐÚãÙ¬°ŽÀÇÛÈÚ»¿â§ÖÓ¯ÇâѾ‰«¶žØëˆÉ¤âáëááЉ³ÃÝÂäí®ªu¢©ÁÛÝŒœØÑÞÅâÇÞ€¤©ÁÓ猜ØÑÞÅâÇÞ€¥ž¯"
providerName="System.Data.SqlClient" />
How to change connection string above into regular string...

You need to know both the encryption algorithm and the key.

im newbie programmer... im not understand...
please advise...

The data is encrypted so if you do not know how it was encrypted there is nothing you can do.
|
|
|
|

Can i change the string with:
<add name="ConnDB" connectionString="Data Source=localhost; Initial Catalog=DB_WB; User Id=sa; Password=123456; Integrate Security=false"
providerName="System.Data.SqlClient" />

Try it and see what happens.

If you typed that into the code, sure, it might work, IF that connection string is appropriate for your database and database engine.
Also, if that is an appropriate connection string, using the SA account is a horrible idea and a huge security risk to your database and the database server, subjecting both to being destroyed. Google for "SQL Injection Attack" for more information on why that is.

That's not how it works.
Even if you had provided a complete and actionable specification, this is not a "write-my-code-for-me" site.
We're happy to help with specific questions about code you have written. But nobody here is going to write the code for you.

You're asking for source code written in a language that's been obsolete for 16 years now.
Yeah, good luck with that.

Hi,
i have a question like ..suppose i have a string= "help" and I want to sort it in an alphabetically order like=ehlp . i need a code for it.

Sorry, but this site does not offer code writing services.
Try it yourself first. If you then got stuck, post what you have done so far and we will try to help.
Another option is searching the web. It should be no problem to find something that can be at least used as starting point.

thanks for your reply can you please tell me from where i can get the code

By using an appropriate search term entered into the input field of your favorite search engine.
If this is some kind of homework you should be aware that your teacher might read here and has done similar research to identify copy and paste solutions.
So the option of doing it yourself is probably the best (and intended!) one.

So i have a accdb name itemdb with table name Products and i want to subtract the value input in the txtbox8 to the field name RegBal
so far i have this code
Imports System.Data.OleDb
Public Class Order
Public conString As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Users\Landon-PC\Documents\Visual Studio 2010\Projects\Final\Final\bin\Debug\itemdb.accdb;Persist Security Info=False"
Public con As New OleDbConnection
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
con.ConnectionString = conString
If con.State = ConnectionState.Closed Then
con.Open()
MsgBox("Connected")
End If
End Sub
Private Sub Button4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Try
Dim sqlQuery As String = "SELECT itemdb.Products, Products.RegBal, Products.RegBal- " & TextBox8.Text & "
Dim sqlCommand As New OleDbCommand
With sqlCommand
.CommandText = sqlQuery
.Connection = con
.ExecuteNonQuery()
End With
MsgBox("SAVED")
Catch ex As Exception
MsgBox(ex.ToString)
End Try
End Sub
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
Me.Close()
Main.Show()
End Sub
End Class

First Richard Deeming is right, do not concatenate SQL strings form user input, wide open to injection attack, use parameterised queries.
That said your SQL will do what you ask, however it is a SELECT statement which will return rows of data to your program, take it that part of your sqlQuery string is missing as you also need a FROM and table name.
You execute it as NonQuery which will return nothing from a SELECT anyway, you need to look at UPDATE if you want to alter the values in table(s).

Hy. I have VB page. Now I added Page_Load with some actions in it and I got error
Error BC30652 Reference required to assembly 'App_Code.ukzuepxw, Version=1.0.6298.24385, Culture=neutral, PublicKeyToken=null' containing the type '[Global]'. Add one to your project.
I fixed it, by commenting the function and reloading the environment. And when I started to run my app, it worked without function off course, because it is commented. So now it looks like there is a problem with function though no syntax error detected. So what I did is I uncommented that function during runtime and reloaded the page. And it works. Could you explain me what`s going on here.

Means VS cannot find the assembly that is to contain that function. Since it is now in comments, the compiler ignores it.
Add a reference to the assembly. Google knows how
