exclusionset of the Igeofeaturelayer interface allows you to exclude some of the features in the layer from being invisible. The Exclusionset property controls which features are excluded from the display through the Ifeatureidset interface, for example, we want to control that features with FID 2, 5, and 8 do not display. Can be implemented with the following code:ILayer PLayer = axMapControl1. Get_layer (0asnew Featureidsetclass ( );p IDSet. ADD (2);p IDSet. ADD (5);p IDSet. ADD (8= Pidset;T

end of an edit operation, the result is indeterminate, depending on the state of the database operation, and even the changes that are made cannot be implemented and an error occurs. For this reason, all editing operations should be in edit operation. Geodatabase ensures that the only instance of the row object in database is during the edit session. A geodatabase does not support nested transactions, and only one transaction can be opened at a time when editing in a version of an environme

The method of AE calling GP tool First, we must first make clear what tools you need to call arctoolbox and what functions to implement. Second, follow the requirements to see how the functionality is implemented in the Arctoolbox tool, and then determine the data source you want. Third, write command or tool tools and write your own functional tools. Finally, a simple kriging interpolation is used as an example to illustrate. (oneself once did not us

Recently, there have been a lot of friends looking for Hawk-eye problems. Ae+c# Eagle Eye in the online code has been a lot of, I also put a version up today, mainly has the following several functions: 1. After the main map window view scope changes, the Eagle Eye window draws a red box to display the current area; 2. When the scale of the main map changes, the scale of the Eagle's eye map also changes, but only the degree of change will be small;

For example, if you want to eat Let's see how greedy the regular expression is. Result: Array([0] => [1] => bread 1 ) 0 indicates the entire character, and 1 indicates the first match. How can we limit greed? Add "?

Application of regular expressions in iOS One, what is the regular expression Regular expressions, also called regular representations, are a logical formula for string manipulation. A regular expression can detect whether a given string conforms to our defined logic, or get the specific part we want from the string. It can quickly achieve complex control of strings in a very simple way. Second, the synt
