Hi albertkhor. I am not sure if this is exactly what you want, but at least it will give you something to work on that I know works because I have just built it for you and am copying and pasting the code.
Start a new project. On the Form put a PictureBox and two buttons. Also from the Toolbox you will need to double-click on an OpenFileDialog. I changed the Name of mine to ofdLookalike.
To the first button click event, put this code:-
Now, put this code in to the second button's click event:-
'Show the open file dialog box.
If ofdLookalike.ShowDialog = DialogResult.OK Then
'Load picture into picture box.
picPictureShow.Image = Image.FromFile(ofdLookalike.FileName)
'Show the name of the file in the Form's caption.
Me.Text = "Picture Show (" & ofdLookalike.FileName & ")"
If I can help you further I shall do my utmost to do so.
MsgBox("Picture Show (" & ofdLookalike.FileName & ")")
Sometimes, just having the tools is not enough - a good guide will show how to use them.
