How to control spin control buttons in test complete?

What language is the application you're testing in?

I have Spin controls in Delphi. Two types. A single button type, and a dual button type. The dual button type presents as two child items which I just click. The single object type simply has "Up" and "Down" methods, so I call those. They're both simple to work with. Have you checked the available methods for it?

Knowing the language you're dealing with and the class name of the control would help ....
