Visual Basic Help please!

[dwj100uni]

Hi all,

I am using Visual Studio to create a form that will allow a user to enter a product code into a field, click enter and the form will display an image that refers to the product.

The product image is always in the same location, "C:\pics\" and is always named after the product code, but with the suffix ".jpg".

I am really struggling to ge this to work as Im not a programmer and don't know where to start, and have searched the net...

Code I have at the mo is;

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

If Dir("C:\pics\" & TextBox1 & ".jpg") <> "" Then

PictureBox1.Image = ("C:\pics\" & TextBox1 & ".jpg")
Else
PictureBox1.Image = ("C:\pics\nopic.jpg")
End If

End Sub

But its not working at all... can anyone help!! Please!!
Thanks,

David

Hi... got it working perfectly with this;

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

If Dir("C:\pics\" & TextBox1.Text & ".jpg") <> "" Then

PictureBox1.Image = Image.FromFile("C:\pics\" & TextBox1.Text & ".jpg")
TextBox1.Text = ""
TextBox1.Focus()

Else
PictureBox1.Image = Image.FromFile("C:\pics\nopic.jpg")
TextBox1.Text = ""
TextBox1.Focus()

End If

End Sub

But how do i link textbox1 to button1_click when enter (return) is pressed on keyboard?

Thanks!!
