Hi Experts,

I want to use internet explorer shortcut keys in my vb.net application. Basically I want to use CTRL+A, CTRL+C and CTRL+V for copy and paste purpose. I am using WebBrowser control in my vb form and have button and text box on it. What I want is when I press the button, It should select All the web content and copy the text in clipboard and paste it back on my textbox. I have tried sendkey with differently but nothing is workout.
Any help will be appreicated. Thanks

 I have used the follwoing code

        WebBrowser1.Focus()
        SendKeys.SendWait("^a")
        '  Threading.Thread.Sleep(1000)

        SendKeys.SendWait("^c")
        '   Threading.Thread.Sleep(1000)
        RichTextBox1.Focus()
        SendKeys.SendWait("^v")

If you are using the WebBrowser control, there are a wide variety of ways to extend and customize the control, which are usually pretty complicated.

Cut, Copy, and Paste operations, though are easy.

Web Browser in C#
http://www.codeproject.com/Articles/60179/Web-Browser-in-C

'cut
Private Sub cutToolStripMenuItem_Click(sender As Object, e As EventArgs)
	getCurrentBrowser().Document.ExecCommand("Cut", False, Nothing)

End Sub
'copy
Private Sub copyToolStripMenuItem_Click(sender As Object, e As EventArgs)
	getCurrentBrowser().Document.ExecCommand("Copy", False, Nothing)

End Sub
'paste
Private Sub pasteToolStripMenuItem_Click(sender As Object, e As EventArgs)
	getCurrentBrowser().Document.ExecCommand("Paste", False, Nothing)
End Sub
'select all
Private Sub selectAllToolStripMenuItem_Click(sender As Object, e As EventArgs)
	getCurrentBrowser().Document.ExecCommand("SelectAll", True, Nothing)
End Sub

Hi TheLearnedOne,
Thanks for reply.
I have modified your code little bit as follows. What I see the its copying the content but not pasting in my textbox automatically. If I press CTRL+V in my textbox I get the content copied in my textbox. Is there any workarround for it.


  Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
        '        getCurrentBrowser().Document.ExecCommand("SelectAll", True, Nothing)
        WebBrowser1.Focus()
        WebBrowser1().Document.ExecCommand("SelectAll", True, Nothing)
        WebBrowser1().Document.ExecCommand("Copy", True, Nothing)
        RichTextBox1.Focus()

        WebBrowser1().Document.ExecCommand("Paste", True, Nothing)

    End Sub

Thanks for help

The ExecCommand works on the WebBrowser control, so Copy would copy from the control, and Paste would paste to the control.  If you want to copy from the clipboard to the TextBox control, then you would need to use the TextBox.Paste method.

Thanks a lot. Its working

my coding is as follows.

  Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        WebBrowser1.Focus()
        WebBrowser1().Document.ExecCommand("SelectAll", True, Nothing)
        WebBrowser1().Document.ExecCommand("Copy", True, Nothing)
        'RichTextBox1.Text = Clipboard.GetText
        Dim oFile As File
        Dim oWrite As System.IO.StreamWriter
        Dim fname As String = "Lab"
        Dim mPath As String = "C:\Temp\"
        Dim mExt As String = ".txt"
        Dim myLab As String = ""
        Dim mFile As String
        Dim mVer As Integer = 1
        mFile = mPath + fname + mVer.ToString + mExt

        For i As Integer = 1 To 10
            If oFile.Exists(mFile) Then
                mFile = mPath + fname + i.ToString + mExt
            Else
                Exit For
            End If


        Next

        oWrite = oFile.CreateText(mFile)
        '  oFile.OpenText()
        Dim data As IDataObject = Clipboard.GetDataObject()
        'If the data is text, then set the text of the
        'TextBox to the text in the Clipboard.
        If (data.GetDataPresent(DataFormats.Text)) Then
            myLab = data.GetData(DataFormats.Text).ToString()
            RichTextBox1.Text = data.GetData(DataFormats.Text).ToString()
        End If
        oWrite.Write(myLab)
        oWrite.Close()
        oWrite.Dispose()
        '        'The OpenText method opens an existing text file for reading and returns a System.IO.StreamReader object. With the StreamReader object, you can then read the file. Let’s see how to open a text file for reading:
        '        Dim oFile As System.IO.File
        '        Dim oRead As System.IO.StreamReader
        '        oRead = oFile.OpenText("C:\sample.txt")
        'Writing to a text file


    End Sub
