hi, why i can open user form using this code yet cannot do for category? when i put 'category.' the suggestion didnt show up 'Show' and when i manually do this, the code is not being recognized by vs.

this is a code at a main form to open subform using tool stripbar.

thank you

The Show() method is part of the System.Windows.Forms.Form class. Your frCategory class must inherit from System.Windows.Forms.Form.
