Hello,
I am working in VB.NET (VS2005)
I need to disabled an item in CheckedListBox.
I know that I have to do as following: chk.items(No).enabled=false.
But in my case it is a little different:
Here is my code:
'In Form1
chk.Items.Add(New clsItem(ID1, Name1))
chk.Items.Add(New clsItem(ID2, Name2))
chk.Items.Add(New clsItem(ID3, Name3))
'Class
Public Class clsItem
Private ID As Integer, Name As String
Public Sub New(ByVal _ID As Integer, ByVal _Name As String)
ID = _ID
Name = _Name
End Sub
Public Overrides Function ToString() As String
Return Name
End Function
Property ItemID() As Integer
Get
Return ID
End Get
Set(ByVal value As Integer)
ID = value
End Set
End Property
Property ItemName() As String
Get
Return Name
End Get
Set(ByVal value As String)
Name = value
End Set
End Property
End Class
How can I disable one of my items now?
Thank you

Hello,
Shay, if you need to disable only single item in the CheckedListBox, you can then try using
the ItemCheck() event of CheckedListBox. For example, in the given code snippet, I have disabled
the second item in the list.
<br />
Private Sub chk_ItemCheck(ByVal sender As Object, ByVal e As System.Windows.Forms.ItemCheckEventArgs) Handles chk.ItemCheck<br />
<br />
If e.Index = 1 Then<br />
<br />
e.NewValue = e.CurrentValue<br />
<br />
End If<br />
<br />
End Sub<br />
You can manipulate it more, by taking a global variable which will hold the index of the row to be
disabled. You can match that variable value with the e.index to decide at runtime which rows to be
disabled.
I hope this will help you.
Regards,
Allen

Thank you, this is a good idea, I will use it.
Does anybody know how to solve it by really disabling the checkbox item as I ask in my first message?
Thank you

Hi all!
I'm trying to do a pretty simple thing in VB6, but it's not working!
In the main form:
Sub Command1_Click()
Dim cls1 As New Class1
cls1.fnc1 StatusBar1.SimpleText
end sub
And in Class1:
Function fnc1(ByRef logText As String)
Dim i as Integer
For i=0 To 10
logText = "We're at number " & i
Next
End Function
I though this would update the statusbar text in real time, but it doesn't work!
Anyone knows why?

Because
Gadjuka wrote: Dim cls1 As New Class1
creates a new Class1, which has no bearing on the instance of Class1 that is running.
Also, why on earth are you still using VB6 ?

Well...some of our customers still have old VB6 applications. Sooner or later we'll upgrade them to .NET, but it takes time...
I tried the same thing in .NET by the way. There I get "A property or indexer may not be passed as an out or ref parameter", so this particular problem doesn't seems to be solved by upgrading.
|

|
|

The status bar will contain only the text that is returned by the function - which will be "We're at number 10" since that is when the function call returns to the called procedure.

Hi Gadjuka,
I think the error message you got when you tried to do this in .Net answers the 'Why' your code doesn't work.
'I tried the same thing in .NET by the way. There I get "A property or indexer may not be passed as an out or ref parameter", so this particular problem doesn't seems to be solved by upgrading. '
So maybe the solution is pretty similar to what you already have. Try this:
<br />
Sub Command1_Click() <br />
Dim cls1 As New Class1 <br />
cls1.fnc1 StatusBar1<br />
end sub<br />
<br />
<br />
Function fnc1(ByRef sb As StatusBar) <br />
Dim i as Integer <br />
<br />
For i=0 To 10 <br />
sb.SimpleText = "We're at number " & i <br />
Next<br />
End Function<br />
<br />
You should be able to pass a reference of the control - I'm pretty sure I've done something along these lines way back when I was doing VB6. I didn't test this but I'm pretty sure it will work. Good luck!

Yepp, that works.
Problem is that I wanted it to be a bit more flexible. To be able to get a log text out from the function whether you want to continuously track the function's progress in the statusbar or write the information to a file.
But I guess this way of doing it (sending in statusbar.simpletext) isn't possible...
I achieved what I wanted by sending in an ordinary string as ref and then have a timer that checks that variable and updates the statusbar.

So pass a flag along with your status bar control to indicate you want to write to the log file, the statusbar or both and write the code to handle the log file in your Class1 class. Then you could call it from your method. Just a thought.
Glad you got it to work in any case, I've rarely found cases where you couldn't find some kind of way to solve the problem. Of course that's why we're software developers - because we like that sort of thing. Cheers!

hi
I want to open multiple websites on a button click.
I M coding like this:
Private Sub btnOpenWebSite_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnOpenWebSite.Click
System.Diagnostics.Process.Start("http://www.rediff.com")
System.Diagnostics.Process.Start("http://www.codeproject.com")
End Sub
but the above code open the 2nd website ie. it open only one website at a time. please help me to open multiple websites on a button click
thanks

That's odd. Perhaps they both open the site in the same browser instance ? There's no other way to do it, unless you host the browser yourself.

hi
thanks for your consideration. I have solved my problem. I m using web browser control and coading like this:
Private Sub btnOpenWebSite_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnOpenWebSite.Click
For i As Integer = 0 To 5
WebBrowser1.Navigate("http://www.codeproject.com", True)
Next
End Sub

Great - that's kind of what I was suggesting.

Hi, hoping you can help. I am trying to add a restore button to the toolstrip on a form. How can i tell if the table adaptor or binding source row data has changed to enable the restore/do you want to save procedure i have set up. Thanks

I'm writing a program and have the following function:
<br />
Public Sub SetInfos(ByVal dir As DirectoryInfo)<br />
m_JBXInfo = dir.GetFiles("*.JBX")<br />
m_JBNInfo = dir.GetFiles("*.JBN")<br />
End Sub<br />
There is more to the function but it is with these lines that I'm having trouble. To test the function I changed one of the JBN file extensions to .JBNp to see if the function would still pull this file, which it shouldn't (at least that's what I thought) because the string pattern is *.JBN. However it still places the *.JBNp file into m_JBNInfo. However can I modify this sub to only pull files with the exact extensions of .JBX and .JBN and not something like .JBNp? Thanks in advance.
