My app lets users create a canned thematic map layer, and them lets them
remove the thematic layer.
MapInfo names the first thematic layer created "Dealers(1)". When it is
removed, and the Create-Thematic-Layer sub is called again, the layer will be
named Dealers(2), and so on. This complicates removing the layer. I loop
through layer names, and remove any layer where LAYER_INFO_TYPE =
LAYER_INFO_TYPE_THEMATIC and Left$(layername,8) = "Dealers(".
This works, but seems a cumbersome and shotgun approach. It works only
because the app, not the user, controls the layers that appear on the map.
Is there a better way to handle the layer removal? Would it be better to
create the thematic layers first, and let the user just turn the layer
displays On/Off? Would we wish for the ability to rename map layers for
better control? Like: Shade Dealers... Title "Dealers by 2001 Sales"?
