I'm a bit new to this, but I'm working on a web browser with tabbed browsing, however..
When a new tab is created, it creates a web browser in it - but I want a function called when the browser is finished loading. I can't create a private sub inside a function, So I am not sure what I should do. Any Ideas?
My Code:
Function addtab()
Dim myTabPage As New TabPage()
Dim theweb As New WebBrowser
myTabPage.Text = "TabPage Test" & (TabControl1.TabPages.Count + 1)
TabControl1.TabPages.Add(myTabPage)
theweb.GoHome()
theweb.Parent = myTabPage
theweb.Visible = True
theweb.Dock = DockStyle.Fill
Return True
End Function
Thanks!
Sounds like you want to create a new webBrowser object, dock it in the new tabPage you make and then have the webBrowser do something when it's finished loading, correct?
What about something like this...
Public Class Form1
Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
addtab()
End Sub
Function addtab()
Dim myTabPage As New TabPage()
Dim theweb As New WebBrowser()
AddHandler theweb.DocumentCompleted, New WebBrowserDocumentCompletedEventHandler(AddressOf Run_Me_On_Load)
myTabPage.Text = "TabPage Test" & (TabControl1.TabPages.Count + 1)
TabControl1.TabPages.Add(myTabPage)
theweb.Navigate("http://justinchoponis.com")
theweb.Parent = myTabPage
theweb.Visible = True
theweb.Dock = DockStyle.Fill
Return True
End Function
Public Sub Run_Me_On_Load(sender As Object, e As EventArgs)
MessageBox.Show("Finished loading")
End Sub
End Class

I have a first form (form_notice_hashtag) called like this:
Public Sub afficher_hashtag(hashtag As String, plateforme_hashtag As String)
Dim form_notice_hashtag_1 As New form_notice_hashtag
form_notice_hashtag_1.StartPosition = FormStartPosition.CenterScreen
form_notice_hashtag_1.Show()
End Sub
In form_notice_hashtag_1, i have a button calling a 2nd form (form_recherche_thesaurus) like this:
Private Sub hashtag_thesaurus_search_button_Click(sender As Object, e As EventArgs) Handles hashtag_thesaurus_search_button.Click
Dim form_recherche_thesaurus_1 As New form_recherche_thesaurus With {
.StartPosition = FormStartPosition.Manual,
.Location = New Point(Me.Left + Me.Width, Me.Top)
}
form_recherche_thesaurus_1.ShowDialog(Me)
End Sub
In form_recherche_thesaurus, i have a datagridview listing some words. The user can select one word, then by clicking a button in form_recherche_thesaurus, the word which will be added to a textbox in form_notice_hashtag
Private Sub thesaurus_ok_button_Click(sender As Object, e As EventArgs) Handles thesaurus_ok_button.Click
Dim list_terms_array As String()
Select Case Owner.Name.ToString
Case "form_notice_hashtag"
list_terms_array = Split(Remove_Duplicates_From_Strings_With_SemiColon(form_notice_hashtag.hashtag_descripteurs_txtbox.Text & ";" & selected_term), ";")
form_notice_hashtag.hashtag_descripteurs_txtbox.Text = (String.Join(";", list_terms_array.Where(Function(s) Not String.IsNullOrEmpty(s))))
End Select
End Sub
I used a select because this mechanism would be used in the same way with other forms than form_notice_hashtag.
Problem: the textbox in form_notice_hashtag is not filled with the selected keywords. I guess it's because of the way form_notice_hashtag is called.
I can't use the solution as explained here Send values from one form to another form because i understood (maybe badly) that this solution works only if the 2nd form (form_recherche_thesaurus in my case) is closed (i.e closing was the trigger) which i don't want.
How can I proceed?
Thanks to jmcilhinney and this page of his blog, here is the solution that allows to transfer several data from a called form (form_recherche_thesaurus) to a calling form (form_notice_hashtag) without closing the called form .
Public Class form_notice_hashtag

Private selected_thesaurus_term As String
Private Sub form_recherche_thesaurus_1_TextBoxTextChanged(sender As Object, e As EventArgs) Handles form_recherche_thesaurus_1.TextBoxTextChanged
Dim list_terms_array As String() = Split(Remove_Duplicates_From_Strings_With_SemiColon(Me.hashtag_descripteurs_txtbox.Text & ";" & form_recherche_thesaurus_1.selected_term), ";")
Me.hashtag_descripteurs_txtbox.Text = (String.Join(";", list_terms_array.Where(Function(s) Not String.IsNullOrEmpty(s))))
End Sub
Private Sub hashtag_thesaurus_search_button_Click(sender As Object, e As EventArgs) Handles hashtag_thesaurus_search_button.Click
Dim form_recherche_thesaurus_1 As New form_recherche_thesaurus With {
.StartPosition = FormStartPosition.Manual,
.Location = New Point(Me.Left + Me.Width, Me.Top)
}
If Me.form_recherche_thesaurus_1 Is Nothing OrElse Me.form_recherche_thesaurus_1.IsDisposed Then
Me.form_recherche_thesaurus_1 = New form_recherche_thesaurus With {
.StartPosition = FormStartPosition.Manual,
.Location = New Point(Me.Left + Me.Width, Me.Top)
}
Me.form_recherche_thesaurus_1.Show()
End If
Me.form_recherche_thesaurus_1.Activate()
End Sub
End Class
Public Class form_recherche_thesaurus

Me.selected_term = Me.thesaurus_search_results_datagrid.Item(0, Me.thesaurus_search_results_datagrid.CurrentRow.Index).Value

So I've been fiddling with this for a while and I don't know if I'm not understanding how the BackgroundWorker works and/or I'm using it wrong or if I'm missing something.
Basically what I'm trying to do is call a BackgroundWorker from a DragDrop function where the user can drop a set of images into the form. The BackgroundWorder then copies the images to a temp location thumbnails are pulled and turned into PictureBoxes and the PictureBoxes are added to a collection. Once the BackgroundWorker is completed the function runs to add all the picture boxes to the form.
All of this is working properly except the progress. The progress function doesn't like to fire until near the end (after almost all the pictures have been copied) during this time the UI is locked (which I'm sure is why the progress function isn't firing) I just can't figure out why the UI is locking.
I've stepped through the code and the ReportProgress method is being called ever loop but the ProgressReported function isn't called until near the end.
HELP! LOL

.... FacePalm.. I figured it out. Apparently during my testing (before I decided to use this control and a background worker, I had added another drag drop function in another area of my code that was being called first. It was taking all the dragged images and turning them into Image data types. The rest of the function was commented out which is why I didn't notice it before because I was only stepping though the classes functions not the functions in the main UI. but it makes perfect sense now, the backgroundworker and the UI function were kicking off at the same time but while the UI thread was processing the Image data typing the report progress calls were stacking up.
After removing that secondary function it works exactly as it should, UI remains fully functional Images and PictureBoxes are processed in the background and the Progressbar updates properly and remains functional as well.
Hellos guys, I'm trying to create tabpages dinamically everytime I clic a button so the problem is when I limit the creation of a tab that exist already, I tried Controls.Find method and got "Value of type 'Control()' cannot be converted to 'Boolean'"... Here is my code in Visual Studio 2015. I will appreciate any help or another method.
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim myTabPage As New TabPage()
TabControl1.Visible = True
If myTabPage.Controls.Find("Pedido", True) Then
TabControl1.SelectedTab = myTabPage
Else
Form1.TopLevel = False
myTabPage.Text = "Pedido"
TabControl1.TabPages.Add(myTabPage)
myTabPage.Controls.Add(Form1)
TabControl1.SelectedTab = myTabPage
Form1.Show()
End If
End Sub
Controls.Find returns an array of controls, not a boolean. So do the following:
If myTabPage.Controls.Find("Pedido", True).Length > 0 Then
EDIT:
With the assumption you are trying to either select or create a tab called "Pedido" (and stripping out some of the code for clarity), try the following:
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
TabControl1.Visible = True
Dim c = TabControl1.Controls.Find("Pedido", True)
If c.Length > 0 Then
TabControl1.SelectedTab = CType(c(0), TabPage)
Else
Dim myTabPage As New TabPage()
myTabPage.Text = "Pedido"
myTabPage.Name = "Pedido"
TabControl1.TabPages.Add(myTabPage)
TabControl1.SelectedTab = myTabPage
End If
End Sub
Is there a way in VB.NET to make components like buttons and menus bars show in design view of you added them in programmatically?

The Designer does only show Controls that are created in the FormName.Designer.vb file. It does not run code in the FormName.vb file. When adding controls in the Designer, they are added to the InitializeComponent() method in the FormName.Designer.vb file.
So the only way to show the controls in the Designer is to add them in the Designer or to edit the FormName.Designer.vb file manually. If you decide for the latter, you should mimic the code that is generated by the Designer very closely in order to avoid problems when the Designer is shown. Also, be prepared that the Designer regards the FormName.Designer.vb file as completely generated code and might decide to recreate the file sooner or later omitting parts that it cannot handle.
Side note: in order to see the FormName.Designer.vb file, you should select "Show All Files" for the project in Solution Explorer.
I have a programs path..like utorrent and it pid too. I have achieved these values programatically using vb.net. I just want to hide their icon form tray just to run them in background and if possible attach the process with a hotkey to call them back. Is there any way to achieve this.
