I want to perform double click on an html element. I can click once, but cant double. I tried to move mouse on element but couldnt find coordinates.

Code:
...
IE.Document.GetElementById(An & "q8").focus  
IE.Document.GetElementById(An & "q8").dblclick ' not working on hmtl 
...
I can't add,change etc html codes. So i can't add or change events, attributes. I need to doubleclick on element directly, maybe mousemove and click or something like that. Double click action selects a value from a popup list, and set it to a inputbox. Keystrokes not working. Client side changes are not applied. I tried to change input value, but when another element's value changes first one returns to original value.

Any idea? I'm realy stuck here

(vb6 and ie8+)
