2 Read Placemarks (location in Google Earth interface) and show, hide
3 Read all layers, show and hide
Next, continue to put the code:

Daosh One, life two, two born Vientiane. Oo's idea is abstract, Vientiane, and complex as a simple. 99% of programmers use OO, or the so-called Class library is designed to be useful, without having to know the internal implementation can directly achieve the desired results. A progress in productivity, A pipeline half-part production process. The programmer is only the last worker to assemble the screw on the assembly line (strictly speaking, the yard farm). C + + is a powerful tool for abstrac

Civil 3D provides. net-based APIs and COM-based APIs. We recommend that you use. net APIs, but sometimes you also need to use COM APIs. This example shows how to use the com api to import DEM data to generate a Civil 3D surface. In Civil 3D development, the reference to be added using the
Following the "C # call GoogleEarth Com API Development (i)", Neil also brings you to the second article. This article, based on the first article, shows how to invoke the Windows API to hide the GoogleEarth interface and display the GoogleEarth map on a custom form. Less nonsense, directly on the code.
