Malfunctioning Cancel button & image

Hello,

I've registered a AddOn in SAP B1 2005 B SP:00 PL:35

Problem--1:

when I press on Cancel Button or cross(X) mark, it hangs and shows me a messages having following lines-----

1)Restart Addon

2)Log off Current Company

3)Continue working without this AddOn

If I choose Restart Addon it shows me a message "failed to connect to the database."

Problem--2:

I added button images on the form and an image for Menu but after registering the Addon those are invisible.

My Code

oCreationPackage.Image = IO.Directory.GetParent(Application.StartupPath).ToString & "\CFL.BMP"

or

oButton.Image = IO.Directory.GetParent(Application.StartupPath).ToString & "\CFL.BMP"

Rgds
