This interface contains a method for drawing layers, defining attributes of the maximum and minimum display scales, space references, names, layer visibility, whether to use layer caching, and whether to display layer prompts, whether the layer is valid, the supported drawing mode, the areas of interest, and the map prompts under the given coordinates are also supported.
EsriCarto ILayer Example
[Limit L Basic 6.0]
Function FindLayerByName (pMap as IMap, sName as string) as ILayer
Dim I as integer
For I = 0 to pMap. LayerCount-1
If pMap. Layer (I). Name = sName then
Set FindLayerByName = pMap. Layer (I)
End if
Next I
End Function
