MapXtreme v7.1 197 Developer Guide
MapXtreme ships with a Search sample application that you can run and learn more about each
search type. The illustration below shows the Search menu with the SearchInfoFactory methods that
use a spatial reference. The Map Search menu has methods for searching based on a drawn screen
geometry object (circle or rectangle). The Query Definition menu highlights the use of various filters
that act on an SQL statement. Find the sample in the
..\MapInfo\MapXtreme\7.x.x\Samples\Desktop\Features\Search folder.
Code Samples
This section includes several code samples that pertain to SearchInfoFactory methods.
SearchNearest
Using the SearchNearest method, the code simulates the Select Point tool behavior to select the
topmost items under a mouse click and add them to the selection.
VB example:
Public Shared Sub MapInfo_Mapping_SearchInfoFactory(ByVal _
mapControl1 As MapControl)
' Get a point from mouse click. Hard coded value use in sample.
Dim pt As System.Drawing.Point = New System.Drawing.Point(100, 100)
' Assumes there is a MapControl with a map in it.
SearchIntersectsGeometry Returns the rows where the table geometry intersects with the
search geometry.
