[OpenLayers-Users] Help with creating custom controls

[Vish Uma]

Hi All,

I am pretty new to OpenLayers and am trying to figure out how I can create a
custom control in OpenLayers that can be placed in the ToolBar  and will be
used to query some data from our server.

I would appreciate it if somebody could point me towards an example or
instructions on how that can be accomplished.

Thank You,
Vish
