This example demonstrates how to Adds labels to the layer without using automated procedures like Labels.Generate. Here is a screenshot with the results of the code execution.

int fieldIndex = 0;

// the old method should be used like this
//axMap1.AddLabel(layerHandle, text, 0, pnt.x, pnt.y, tkHJustification.hjCenter);
sf.Labels.Synchronized = true;
