Emulate Picture Box double click

I have the following code

Private Sub PictureBox_DoubleClick(ByVal sender As System.Object,
ByVal e As System.EventArgs)
Try
Dim p As PictureBox = CType(sender, PictureBox)
Dim filetemp As String
filetemp = Replace(p.Tag, "Thumb", "jpg")
If Me.UseEditor = True Then
System.Diagnostics.Process.Start(filetemp)
Else

End If

_Image = Image.FromFile(filetemp)

Catch ex As Exception
Throw New Exception("PictureBox_DoubleClick", ex)
End Try

End Sub

Is there a way to emulate this functionality by single clicking the
image to select and and then click a button on the form to perform the
same action as the above code? If so, please could you provide sample
code.

Thanks.

Extract the code into a separate routine and call it wherever you want
to call it from.

Private Sub EditPicture( ByVal sender as PictureBox )
'Try
Dim p As PictureBox = CType(sender, PictureBox)
Dim filetemp As String _
= Replace(p.Tag, "Thumb", "jpg")
If Me.UseEditor = True Then
System.Diagnostics.Process.Start(filetemp)
Else
???
End If

_Image = Image.FromFile(filetemp)

'Catch ex As Exception
' Throw New Exception("PictureBox_DoubleClick", ex)
'End Try
End Sub

.... then ...

Private m_CurrentPicture as PictureBox = Nothing

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

m_CurrentPictureBox = DirectCast( sender, PictureBox )

End Sub

Private Sub Button7_Click(ByVal sender As System.Object _
, ByVal e As System.EventArgs)

EditPicture( m_CurrentPictureBox )

End Sub

You'll note I've commented out your Exception Handling in EditPicture -
there's no point catching an Exception unless you're going to do
something /useful/ with it (and, IMHO, wrapping a nice, specific
Exception in a System.Exception isn't).

Hi,
As Picturebox is a control, and control class has OnDoubleClick method
to raise DoubleClick event. So you can directly call it from anywhere
and you'd better look at that method:

Hope this helps,
