Cntl - A or Cntl-F in a multiline text box

Cntl - A or Cntl-F in a multiline text box

• Ernest Wilkerson

  Hi,

  The &&, == represents logical operator in VB. '&&' - AND, '==' would just be plain =.  You can place it in the KeyDown event of your textbox. So to translate the code:

  If e.Control AND e.KeyCode = Keys.A Then
  TextBox.SelectAll()
  End If

  But the documentation clearly states that by enabling the ShortcutsEnabled property of a textbox the ctrl+a function would readily be used. Heres the doc http://msdn2.microsoft.com/en-us/library/1y92bbh2. I suggest you report this to Microsoft Feedback Center...

  Finally,
  
  The double-click worked.
  
  However, the a still showed.  Let's see if I had that code right.
  
  

  Private Sub txtGeneralText_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles txtGeneralText.KeyDown

  If e.Control And e.KeyCode = Keys.A Then

  'If e.Control And e.KeyCode = Keys.Control Then

  txtGeneralText.SelectAll()

  txtGeneralText.Copy()

  e.Handled = True

  End If

   

   

  End Sub

  Hi,

  Pressing "A" before ctrl would indeed show the letter a. If you will press ctrl first, then the letter a won't show. But if in some case that you really wouldn't want the user to enter a letter "A" then you can also handle that. Try adding this code on the keydown event...

  If e.KeyCode = Keys.A Then
  e.Handle = True
  End If

  thanks.
  
  Eventually I would have figured out if e.control and keycode.F then...
  
  but I wouldn't have included the rest.

  edit:  As it turns out this doesn't work.  The search dialog doesn't appear.  Furthermore, only the first searchstring is highlighted.

  Hi,

  I just copy pasted your control in a new vb project and it works perfectly fine. This puzzles me. BTW, when is the "a" showing before or after the highlight

  I only know visual basic.  && and == don't show up in the documentation.

  I also don't know where to place the code.  MouseDown

  Thanks for your answer.

  edit.  The example they give in the October msdn is
  
  Public Sub CopyAllMyText()
      ' Determine if any text is selected in the TextBox control.
      If textBox1.SelectionLength = 0 Then
          ' Select all text in the text box.
          textBox1.SelectAll()
      End If
      ' Copy the contents of the control to the Clipboard.
      textBox1.Copy()
  End Sub
  
  
  But how do I call that sub

  How do I implement cntl-F

  In the keydown event I tried no code at all.  Didn't work.

  tried e.KeyCode = Keys.F.  Message - property keycode is read-only.

  How do I do it

  You have to do it yourself
  
  if ( (e.Control) && (e.KeyCode==Keys.A))
  {
  TextBox.SelectAll();
  }

  Hi,

  I just sent you a mail containing the project that I tinkered with. Try tweaking it and to find out what part of your code is missing...

  BTW, got a problem on sending a rar file to gmail. So I removed the extension. Just rename the file to .rar upon downloading.

   

  cheers,

  First I press the a.  It shows.  Then I press cntl a and it selectsall and copies.

  Thanks, Paul, I'll give it a try.
  
  dennist685
  
  edit.  I tried it.  The trouble is, the 'a' actually appears in the text before the shortcut works.
  
  dennist685
  
  Things are even stranger.
  
  I tried
  

  Private Sub txtGeneralText_DoubleClick(ByVal sender As Object, ByVal e As System.EventArgs) Handles txtGeneralText.DoubleClick

  If e.Control Then

  txtGeneralText.SelectAll()

  txtGeneralText.Copy()

  End If

  End Sub
  
  And got control is not an member of system.events.arg.  Why is it OK for KeyDown but not double click
  
  I tried
  
  

  If e.Control And e.KeyCode = Keys.Control Then

  but that doesn't work.  Why

  Paul,
  
  worked fine.  thanks.
  
  Whew!
  
  I'll skip preventing the user from typing in whatever letters he wants, but thanks for that information as well.

  Hi,

  Yes, the routine that was posted would never work on double click. (Is double click on textbox defaults to highlight all-text )

  In your other inquiry, about the letter a showing in the textbox. You could override this by placing e.Handled = true before the end if declaration...

  Place Directly in DoubleClick event to work:

  txtGeneralText.SelectAll()
  txtGeneralText.Copy()

  remove the if e.control statement....

  Hi,

  This is much trickier that Ctrl+A. Try pasting this code in the KeyDown event of the textbox. Just after the ctrl+A statement...

          If e.Control And e.KeyCode = Keys.F Then
              Dim searchString As String
              Dim pos As Integer
              searchString = InputBox("Place search String")
              If searchString <> "" Then
                  pos = InStr(TextBox1.Text, searchString)
                  TextBox1.Select(pos - 1, searchString.Length)
              End If
          End If
  

  cheers,
