I want to generate a web popup window when a user clicks a linklabel in my VB application.
Ideally the popup window will be using whatever the users default browser is.
Is this possible?
Any ideas how?
Thanks :)
Process.Start(Url)
should do what you want.
use Process.Start("http://www.google.com") on click event
Use Process.Start in the LinkClicked event of the LinkLabel
Private Sub LinkLabel1_LinkClicked(sender As Object, e As LinkLabelLinkClickedEventArgs) Handles LinkLabel1.LinkClicked
Process.Start("http://www.bbc.co.uk")
End Sub
If you want to specify the URL at some point earlier you could store this in the Tag field:
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
LinkLabel1.Tag = "http://www.bbc.co.uk"
End Sub
Private Sub LinkLabel1_LinkClicked(sender As Object, e As LinkLabelLinkClickedEventArgs) Handles LinkLabel1.LinkClicked
Process.Start(LinkLabel1.Tag.ToString)
End Sub

i'm just a beginner here, please help me to solve my problem, and actually i didn't have a code yet for this.
i have a 2 flow out panel and have a buttons. the Menu button in the upper side and the Menu button in the bottom side. how can i click them at the same time?
No you cannot do that, but there is a way to achieve your problem,
Do something like this,
This is only a suggestion..
Private Sub btnMenuUpper_Click(sender As Object, e As EventArgs) Handles btnMenuUpper.Click
'Code Here
End Sub
That's the first button and that will be activate also the second button.
Private Sub btnMenuBottom_Click(sender As Object, e As EventArgs) Handles btnMenuBottom.Click
'Code Here
End Sub
And just call the btnMenuBottom to btnMenuUpper.
Private Sub btnMenuUpper_Click(sender As Object, e As EventArgs) Handles btnMenuUpper.Click
'Code
btnMenuBottom_Click(sender, e)
End Sub
This should work
Private Sub btn1_click(sender as object, e as EventArgs) handles btn1.click
btn2.performclick
end sub
I am using the Skype4ComLib library to try and send an image to a contact on Skype.
Private Sub Button17_Click(sender As Object, e As EventArgs) Handles btnImageLoad.Click
OpenFileDialog1.ShowDialog()
PicBox.ImageLocation = OpenFileDialog1.FileName.ToString
End Sub
This opens a dialog box for the user to select an image and loads it into a picture box called PicBox.
Private Sub Button15_Click(sender As Object, e As EventArgs) Handles Button15.Click
TimerImage.Stop()
End Sub
Private Sub Button15_Click(sender As Object, e As EventArgs) Handles Button16.Click
TimerImage.Stop()
End Sub
Buttons 15 and 16 start the timer.
I want to send the image from within the timer but I can't use skype.sendmessage as it only accepts a string.
Any ideas?
Using the SendKeys.Send method you can paste the picture from the clipboard in the message via the actual Skype application.
This is how I do it:
My.Computer.Clipboard.SetImage(PicBox.Image)
SkypeClient.Client.OpenMessageDialog("<contact to send to>")
SkypeClient.Client.Focus()
SendKeys.Send("^(V){ENTER}")
Replace <contact to send to> with the name of the contact you want to send the picture to.
This I thought would be easy. I have not used VB.NET all that much, and I am trying to open up a form from a button click. The form will not show and I get a null exception error.
What is wrong with the code?
Private Sub Button3_Click(sender As System.Object, e As System.EventArgs) Handles Button3.Click
Dim A
A = AboutBox1
A.Show()
End Sub
Private Sub Button3_Click(sender As System.Object, e As System.EventArgs) _
Handles Button3.Click
Dim box = New AboutBox1()
box.Show()
End Sub
You can also use showdialog
Private Sub Button3_Click(sender As System.Object, e As System.EventArgs) _
Handles Button3.Click
dim mydialogbox as new aboutbox1
aboutbox1.showdialog()
End Sub
You could use:
Dim MyForm As New Form1
MyForm.Show()
or rather:
MyForm.ShowDialog()
to open the form as a dialog box to ensure that user interacts with the new form or closes it.
You may like to first create a dialogue by right clicking the project in solution explorer and in the code file type
dialogue1.show()
that's all !!!
***THE CODE FROM THE FIRST WINDOW GOES INTO A TEXT BOX AND YOU HIT THE BUTTON HERE.
Private Sub btnOk_Click(sender As Object, e As EventArgs) Handles btnOk.Click
Me.Close()
End Sub
***THE CODE ON THE FORM WHERE I WANT THE INFO TO BE PLACED IS HERE.
Private Sub Loan1Form_Load(sender As Object, e As EventArgs) Handles Me.Load
Me.lblCompanyName.Text = DataEntryForm.txtCompanyNameInput.Text
End Sub
Anyway's that's what I found on a youtube video and im having trouble getting it to work. Any help would be appreciated.
Thanks.
Pass the data to an instance of the form:
Private Sub btnOk_Click(sender As Object, e As EventArgs) Handles btnOk.Click
Dim f As New OtherForm
f.lblCompanyName.Text = txtCompanyNameInput.Text
f.Show()
Me.Close() 'make sure this form is not the one that closes the app if it closes
End Sub
If I want to set the focus on a textbox when the form is first opened, then at design time, I can set it's tabOrder property to 0 and make sure no other form control has a tabOrder of 0.
If I want to achieve the same result at run-time, using code, how should I proceed?
Are there alternatives to using tabOrder?
I assume any run-time code will be in the form's constructor or its onload event handler?
EDIT
In other words I'd like to be able to type straight into the textbox as soon as the form appears without having to manually tab to it, or manually select it.
Because you want to set it when the form loads, you have to first .Show() the form before you can call the .Focus() method. The form cannot take focus in the Load event until you show the form
Private Sub RibbonForm1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Me.Show()
TextBox1.Select()
End Sub
I think what you're looking for is:
textBox1.Select();
in the constructor. (This is in C#. Maybe in VB that would be the same but without the semicolon.)
From http://msdn.microsoft.com/en-us/library/system.windows.forms.control.focus.aspx :
Focus is a low-level method intended primarily for custom control
authors. Instead, application programmers should use the Select method
or the ActiveControl property for child controls, or the Activate
method for forms.
Private Sub Form1_Shown(sender As Object, e As EventArgs) Handles Me.Shown
TextBox1.Select()
End Sub
Using Focus method
Private Sub frmTest_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
yourControl.Focus()
End Sub
To set focus,
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs)
TextBox1.Focus()
End Sub
Set the TabIndex by
Me.TextBox1.TabIndex = 0
Quite simple :
For the tab control, you need to handle the _SelectedIndexChanged event:
Private Sub TabControl1_SelectedIndexChanged(sender As Object, e As System.EventArgs) _
Handles TabControl1.SelectedIndexChanged
If TabControl1.SelectedTab.Name = "TabPage1" Then
TextBox2.Focus()
End If
If TabControl1.SelectedTab.Name = "TabPage2" Then
TextBox4.Focus()
End If
I think the appropriate event handler to use is "Shown".
And you only need to focus the appropriate text box.
Private Sub Me_Shown(sender As Object, e As EventArgs) Handles MyBase.Shown
myTextbox.Focus()
End Sub
create a textbox:
<TextBox Name="tb">
..hello..
</TextBox>
focus() ---> it is used to set input focus to the textbox control
tb.focus()
