The pointer in the first byte points to a block of memory named Itable (called Itab in C). The Itable header stores some type-related metadata, and then the list of function pointers. The itable corresponds to an interface type, not a dynamic type. In our case, Stringe
ArcGIS Engine efficiency exploration--adding and deleting features, reading and updating attributesFrom: http://blog.csdn.net/freewaywalker/article/details/23703863Category: Arcnotes2014-04-14 20:56 1781 people read comments (0) favorite reports 1. Adding a featureIn ArcGIS engine, there are two main methods for adding features:
Using Ifeatureclass.createfeature followed by Ifeature.store
Using Ifeatureclass.createfeaturebuffer with an INSERT cursor

In modern learning and office, the use of forms is often exposed, such as various documents, statements, accounts, etc. The same inevitably applies to various data tables in PowerPoint presentations. I found a new way to insert a table in ppt, but I used a free one.

In the following example, the "name_city" field is added to the current map in mapControl. IField, IFieldEdit, ITable (IClass), IFeatureLayer, IFeatureClass, and IFeature fields are used. IField, IFieldEdit is used to create a new field "name_city". The "name_city" Field of each element is stored as "city_name ".
Note: when calling the AddField method, use ITable or IClass instead of IFieldsEdit. Refer to t
