[RESOLVED] Passing checked items/process to other form

**chris-2k** · May 8th, 2013, 09:27 AM

Hi,

Anyone can help, pass all checked listview items into my install form??

And then start process in install form... Here's what I have:

Code:

If ListView1.CheckedItems.Count > 0 Then
            For Each Item As ListViewItem In ListView1.CheckedItems
                '//Install
                'install = lVI.Checked
            Next
            Me.Hide()
            InstallPrograms.Show()
        Else
            MessageBox.Show("Nothing selected to install!")

        End If

Just a suggestion, there could be other ways. But I had a similar problem last time and was recommended something like this.

Create a module with a class of booleans for each install checkbox.
If the checkbox is checked change that boolean to True.

vb.net Code:

Module Module2
 
    Public setting As New installsettings
 
    Public Class installsettings
 
        Public Property var1 As Boolean
        Public Property var2 As Boolean
        Public Property var3 As Boolean
        Public Property var4 As Boolean
 
    End Class
End Module

Then for each check box do something like this

vb.net Code:

Private Sub chkvar1_CheckedChanged(sender As System.Object, e As System.EventArgs) Handles chkvar1.CheckedChanged
        if chkvar1.Checked = True then
            setting.var1 = True
        else
           settings.var1 = False
        End if
    End Sub

Then in your install Form you can access them like this

vb.net Code:

if settings.var1 = true then
   'Install var1....
End if

So you're saying to replace all this:

Code:

Public Class InstallPrograms
    Dim pCount As Integer
    Dim p() As Process
    Dim inifile As String = Application.StartupPath + "/Start/InstallCFG.ini"
    Dim stream_reader As New IO.StreamReader(iniFile)
    Dim line As String
    Dim ReadResult() As String

    Sub Form1_KeyUp(ByVal sender As Object, ByVal e As KeyEventArgs) Handles MyBase.KeyUp
        If e.KeyData = Keys.F1 Then
            Editor.ShowDialog()
        End If
    End Sub

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        line = stream_reader.ReadLine() 'Read InstallCFG.ini File

        Do While Not (line Is Nothing)
            ReadResult = line.Split(":") 'Split line at :

            If (ReadResult(0).ToLower() = "prog name") Then
                Label3.Text = "Installing " + ReadResult(1)
            End If

            If (ReadResult(0).ToLower() = "installer file") Then
                PictureBox1.ImageLocation = ".\images\System-Working.gif"
                Label3.Refresh()
                Label5.Refresh()
                Dim info As New System.Diagnostics.ProcessStartInfo
                info.FileName = ReadResult(1) 'Open the application

                Dim myProcess As New System.Diagnostics.Process
                myProcess.StartInfo = info
                myProcess.Start() 'Start the process
                myProcess.WaitForExit() 'Wait until the process started is finished
                myProcess.Close() 'Release the resources
                Label5.Text = "Install Complete..."
                Label5.Refresh()
                System.Threading.Thread.Sleep(750)
                Label5.Text = ""
                Label5.Refresh()


            Else
                MessageBox.Show("Something is wrong! File = " & ReadResult(1))
            End If

            line = stream_reader.ReadLine() 'Move on to the next line.
        Loop
        stream_reader.Close()

        ' We'll assume you have all the filepaths in a listbox
        ' it would work the same for any other collection type

        pCount = ListBox1.Items.Count
        ReDim p(pCount - 1)

        For i = 0 To pCount - 1
            p(i) = New Process With {.EnableRaisingEvents = True}
            AddHandler p(i).Exited, AddressOf ProcessExit
            p(i).StartInfo.FileName = ListBox1.Items(i).ToString
            p(i).Start()
        Next

    End Sub

    Private Sub ProcessExit(ByVal sender As Object, ByVal e As System.EventArgs)

        pCount -= 1
        If pCount = 0 Then
            MsgBox("All Done")
        End If

    End Sub
End Class-

with ur code......

No not at all, I am saying use my code and place it into your so you can pass the status of your chk boxes to your other form.
Although I feel like I mis understood your question

My Understanding:

You have a form with a list of items to install. The user selects what items he wants installed and you want to know how to get that list of checked items to your other installer form?

**chris-2k** · May 8th, 2013, 04:26 PM

Hmmmm... Is there a way to read the last column in the listview?

As i have the file location in a column......

**chris-2k** · May 8th, 2013, 06:51 PM

Can i do:

Code:

For Each App In SelectPrograms.App_List.Items(3).SubItems.ToString
     '//Install App
Next

i'm assuming columns start at 0

**chris-2k** · May 9th, 2013, 09:42 AM

Anyone?

**Crzyrio** · May 9th, 2013, 09:53 AM

You can specify which sub item it is by the name of the colum like so

vb.net Code:

ListView1.Items(3).SubItems("Name of colum")

So in that case it will return the value of the column specified of item 3.

If you are trying to get all the items in that colum you can do this

vb.net Code:

For Each item As ListViewItem In ListView1.Items
 
            item.SubItems("Name of colum").ToString()
 
 
        Next

EDIT: Let me double check this, I am more farmiliar with datagridview, but they seem very similar

**chris-2k** · May 9th, 2013, 10:07 AM

OK I shall try.......

**chris-2k** · May 9th, 2013, 10:20 AM

Ok i think that would work, now how would I pass checked items?

**Crzyrio** · May 9th, 2013, 10:56 AM

What exactly do you want to pass?

Your list view contains check boxes, and for every box checked you want to pass what is contained in those rows?

**chris-2k** · May 9th, 2013, 11:15 AM

I need to pass listview items (checked items) to Form2 and then start the process.....

I've got (form1, pass items):

If App_List.CheckedItems.Count > 0 Then
For Each Item As ListViewItem In App_List.CheckedItems
'Need to pass checked items to the install form, but how ?
Next
Me.Hide()
InstallPrograms.Show()
Else
MessageBox.Show("Nothing selected to install!")
End If

And (form2, to start the process):

For Each App In SelectPrograms.App_List.Items(3).SubItems.ToString
Label3.Refresh()
Label5.Refresh()
Dim info As New System.Diagnostics.ProcessStartInfo
info.FileName = App

'ReadResult(1) Open the application

Dim myProcess As New System.Diagnostics.Process
myProcess.StartInfo = info
myProcess.Start() 'Start the process
myProcess.WaitForExit() 'Wait until the process started is finished
myProcess.Close() 'Release the resources
Label5.Text = "Install Complete..."
Label5.Refresh()
System.Threading.Thread.Sleep(750)
Label5.Text = ""
Label5.Refresh()

line = stream_reader.ReadLine() 'Move on to the next line.
Next

I have the file location in the last column..

**Crzyrio** · May 9th, 2013, 02:04 PM

Since you are just hiding the first form, you should be able to simply do this in form2

vb.net Code:

Form1.App_List.CheckedItems

**chris-2k** · May 9th, 2013, 03:08 PM

Ok i've come up with:

Code:

For Each App As ListViewItem In SelectPrograms.App_List.CheckedItems
            Label3.Text = "wooork" + App.SubItems(0).Text
            Label3.Refresh()
            Label5.Refresh()

            Dim p As New System.Diagnostics.Process
            p = App.SubItems(3).Text

            Dim myProcess As New System.Diagnostics.Process
            myProcess.StartInfo = p
            myProcess.Start() 'Start the process
            myProcess.WaitForExit() 'Wait until the process started is finished
            myProcess.Close() 'Release the resources
            Label5.Text = "Install Complete..."
            Label5.Refresh()
            System.Threading.Thread.Sleep(750)
            Label5.Text = ""
            Label5.Refresh()
       .Next

but 1 error, can ya help?

Error 1 Value of type 'String' cannot be converted to 'System.Diagnostics.Process'. H:\X17-59183\PostInstall\PostInstall\InstallPrograms.vb 25 17 PostInstall

it is because of this line

vb.net Code:

Dim p As New System.Diagnostics.Process
            p = App.SubItems(3).Text

You are saying that your process is = to a line of text. What are you trying to do there?
