Draw text

This sample application demonstrates the splined text rendering capabilities of ArcObjects. You click the map to track a line, then use the MapControl DrawText method to place the text in the text box along the tracked line. At least two mouse clicks are required for the line and text to appear on the MapControl.

This sample uses the AddShapeFile method to load the world countries sample data, which is then symbolized. The OnClick event uses either the TrackRectangle method to zoom in if the right or middle mouse button has been used, or adds the new point to the line and updates the display through the Refresh method. The Refresh method is used to draw the esriViewForeground phase, thereby, removing any previously drawn annotation and triggering the MapControl OnAfterDraw event. The OnAfterDraw event uses the DrawShape and DrawText methods to draw the line and text onto the MapControl in response to the refresh of the esriViewForeground phase.
