C # FAQs about secondary development based on AE Components, Because I am engaged in. net platform for secondary development of GIS, so the first blog post will talk about: I recently encountered a common problem in the project, if you can add a little convenience to everyone, it is also my pleasure. If you have any comments or suggestions on this blog post, you are welcome to discuss with me and make progress together. 1: The call to the COM compon

processing of timed events.Redis processing events are single process single-threaded, while classic Reator mode is serially processed for events.That is, if an event is blocked for too long, it can cause the entire redis to be blocked.The following is a brief analysis of the Redis AE event-handling model.You can see from the code that it mainly supports Epoll, select, Kqueue, and the Solaris event ports.There are two main types of event drivers avai

I have just implemented some functions related to property query. Here I will summarize them. If there are errors and inspecies, we also hope that experts in GIS and AE development will give some advice. // ****** The second part has a dot error.

Scenecontrol + AE + scroll wheel Scaling To set the scroll wheel scaling for scenecontrol, you must define the delegation. Because scenecontrol does not have a wheel event, the from wheel event must be delegated.

During the AE development process, some objects must be temporarily stored, such as element, layer, map, and symbol. arcengine provides methods for serializing objects to save this information. All serializable objects support the ipersiststream interface (For details, refer to the help group documentation ). ixmlstream is also an important interface. for more information, see the help documentation. This article is inspired by the technical docume

In AE development, we often encounter the need to export the current scenario in map, scene, and globe as an image. below is my summary of the export method, where two-dimensional can be exported to the memory or hard disk, you can also export the space data file of the image, which can only be exported to the hard disk in 3D, with the source code (VB. net), the usage is detailed in summary, ^ _ ^ ''' ''' Two-dimensional export the current scenario is

The toolbar has been encapsulated in AE. You only need to drag this control and set several properties to implement the corresponding functions in the desktop. (1) drag a arcengine toolbarcontrol on the form (2) Right-click toolbarcontrol --> Properties 1> under the items tab, select the tool to be added. You can see that commands and toolset do not include most of the functions of map browsing, property query, and space analysis. Customized deskt

There are many methods for reclassifying raster data. AE can be implemented in multiple ways, either by map algebra (implemented in RasterModel), IReclassOp, or Geoprocessor, it can even be implemented by traversing the raster. This is the most primitive method, but it may also be the most practical. The original raster Traversal method is used here. [Csharp] private void reclass (IRaster pRaster, float weight) {IRasterProps rasterProps = (IRasterProp
