Obtain the checkedlistbox value

I am positive that your VC++ programmer will understand the steps that need to be taken. VB.NET is fairly easy to read for a C++ programmer.

You can always come back here if you get stuck Smile | :)

I have the following code to populate a checkedlistbox

'Sets up dataset
Dim ds2 As New DataSet
ds2 = Populate_Employees()

'Sets the checkedlistbox to the dataset and sets the displaymember and valuemember
clb_employee.DataSource = ds2.Tables("Employees")
clb_employee.DisplayMember = "Username"
clb_employee.ValueMember = "Employee_ID"

Now all i want to do is iterrate throught the checkedlist box and return the value of those that are checked.

Can anyone shed some light upon this for me?

Hi Mc--Gann,

The code bellow should help:

'loop through check box list
For i=0 To clb_employee.Items.Count - 1

If clb_employee.Items(i).Selected Then
'Do something with the selected value
strValue = clb_employee.Items(i).Value.ToString

End If

Next

I hope this helps.

Problem with WinForm Application Tab Control using VB.NET2008 Framework 2.0

Sorry, my mistake, I didn't realise it was a windows application. How about trying this:

Dim obj As Object
For Each obj In clb_employee.CheckedItems
strValue = obj.ToString
Next obj

Hopefully this will work better for you.

Hello all,

I would like to make the Tab movement can also pressing the "Enter" Key. I have google and found the code which possible to used. But I found its not running fine with me. When I press "Enter" key,it runs fine for the tab movement.
But if I put something into my textbox,it only allowed me to put 1 character and it will move next. Anyone can help me solve this? Because the Textbox 2 can able to put in any kind of numbers. But after add in the code that allowed "Enter" key move the Tabindex,it will move to the next tab index after I lick 1 character.

Please help me to check is that I use this code wrongly?

Private Sub TextBox2_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox2.KeyPress

        If Keys.Enter Then
            SendKeys.Send("{TAB}")
            Exit Sub
        End If

        Select Case e.KeyChar
            Case "0" To "9"
            Case Microsoft.VisualBasic.ChrW(8) 'backspace
                'Case Microsoft.VisualBasic.ChrW(46) 'dot (.)
                '    If InStr(TextBox2.Text, ".") > 0 Then
                '        e.Handled = True
                '    End If

            Case Else
                e.Handled = True
        End Select

    End Sub

Thanks you all so much for reading. Anyone can give me some suggestion how should I do to make the "Enter" key press work as tab?

How to get the attachment ContentID from an Outlook.MailItem

Hi there,

I'm trying to write a piece of code to convert an Outlook OFT file into a html file.
(If you try SaveAs HTML from Outlook, it doesn't save the attached images)

Using the Outlook.MailItem object, I can iterate through the attachments, but I cannot seem to locate the ContentID for the attachments (I need this in order to figure out which image attachment belongs to which tag).

Anybody done this before?

Thanks,

David

How do you trap mouse clicks for save, copy and print?

AndyASPVB19-Apr-09 2:33

Re: How do you trap mouse clicks for save, copy and print?

19-Apr-09 2:33

Hi
I am looking to see if I can trap when a user clicks on the save and print icons using their mouse in word. Now, you probably asking what a stupid question, but stick with me! What I have is this, I have an ASP web site running through my bespoke web browser control, and in my website running on an intranet, I have an iframe, which in turns shows a word document.

However, when the word document is displayed it has all the word tool bars. The easiest way would be turn things off registry wise, but this, I am told, would go if the user was to use it normally. Unfortunately, I haven't been able to use an Active X control, for some reason that gives me back blank. So, I was wondering if there is a way of trapping these events through the browser control as we don't want the user to do anything locally.

I am okay with hot keys, it is how to stop mouse events.

Last thing, I am not looking for anything complicated, just simple, nice and neat code would be great!

So your form has a browser control, and in that, you show a word document ? I think you're fighting a losing battle - the user can configure that toolbar, right ? So how would you know what button was at a specific mouse point ?

Protected Overrides Function ProcessCmdKey

Hi
I just need some help to refine some code I am writing inside the function above in Windows form, which includes a web browser control.

In my code so far I have written if msg.WParam = keys.controlkey then return true. Now this works fine, but what I am really trying to do is capture key combinations, like control & c. So, I changed it and said if msg.WParam = keys.controlkey And msg.WParam = keys.c then return true. Unfortunately, it is only capturing the control key, and if I change it to an OR then it only captures the c, which is not what I want.

Is there a quick way to get both at the same time? I am not looking for lots of complicated code, just something neat and simple.

Hi,

msg.WParam cannot have two different values at the same time.

you can get the instantaneous value of the modifier keys through Control.ModifierKeys, so check that together with msg.WParam==(int)'c'

If you are trying to capture the Ctrl Key plus an alpha char, like 'C', in ProcessCmdKey I believe the following will work:

If keyData = (Keys.Control + Keys.C) Then
   ' whatever
   Return True
End If

In this case the keyData parameter is handier than the message parameter.

AndyASPVB19-Apr-09 5:11

19-Apr-09 5:11

Hi
Thanks for your advice

I tried it and it skipped over the if statement. In debug mode I hovered over the keyData variable and its value was 131089, whereas keys.control was 131072 and C was 67. Therefore, it will never equate to true.

Also I noticed that won't work because the function is fired twice, which must be because there is two key strokes?

Does anyone have any ideas?

Have you tried running the code without stepping through the debugger? I believe ProcessCmdKey may fire twice under this scenario with the first firing showing keyData as the modifier key values summed (e.g., Keys.Control + Keys.ControlKey), and the second firing being, from my code example (Keys.Control + Keys.C).

At any rate, I know the sample I gave you works for me with VS 2003 or VS 2005 for capturing modifier key combinations in ProcessCmdKey (whether it be Alt or CTRL with another key). If it really is not working for you, I'm sorry I don't know why. I have not tried this under VS 2008 and, if that is what you are working under, maybe there is some slightly different behavior.
