Question

I have a need to run different code when a user clicks or double-clicks an item in a VB6 ListBox control. When I click on the control, the Click event handler executes. However, I am finding that when I double-click on the control, both the Click and DblClick event handlers execute.

Anyone have a good solution for getting just the DblClick event handler code to run without the Click code being executed first?

Thanks in advance for any suggestions.

A slight hack, but you could use a Timer control and a boolean variable:

• Start the timer on the Click event, set the boolean variable to false
• Set the boolean variable to true on the DoubleClick event
• When the timer Tick event fires, check the boolean variable to see if the user did a Click or DoubleClick

I’d recommend setting the timer interval to the Windows double click time setting, plus a bit (There should be a Windows API call that will give you this value).
