The MouseIcon property provides a custom icon that is used when the MousePointer property is set to esriPointerArrowHourglass (99).
In most development evironments the control's property pages can be used to load either a cursor (.cur) or icon (.ico) file. A cursor contains a custom 'hotspot' location and can be any size. The 'hotspot' location for an icon file defaults to the center of the icon. This property cannot be used to load animated cursor (.ani) files.
To programatically create an object implementing IPictureDisp there is the win32 function OleLoadPicture or helper methods depending on the development environment.

throws IOException,
AutomationException
This property is a shortcut to IMap::SpatialReference. The Map's SpatialReference will be set automatically to match the SpatialReference of the first Layer added to its layer collection. If the first Layer added has no SpatialReference defined, the coordinates in the Layer will be analyzed. If the coordinates range from 0 - 180, the MapControl assumes the layers data is geographic (i.e. contains unprojected coordinates in latitude and longitude) and the SpatialReference will appear as "GCS_Assumed_Geographic_1". If the MapControl cannot determine that the data source is geographic, the current SpatialReference will be "Unknown". The SpatialReference is also "Unknown" if the MapControl contains no data.

public double getReferenceScale()
throws IOException,
AutomationException
This property is a shortcut to IMap::ReferenceScale and is the scale to which all symbol and text sizes used in the Map will be made relative.
A ReferenceScale set to 0 indicates that no ReferenceScale is set and is the default. When no ReferenceScale is set, the size of any symbols or text on the Map remains the same irrespective of MapScale. When a reference scale is set, the size of any symbols or text on the map changes as the MapScale changes. For example, text labels will get larger if you zoom in to a scale larger than the ReferenceScale and smaller if you zoom out to a scale smaller than the ReferenceScale.

public double getMapScale()
throws IOException,
AutomationException
This property is a shortcut to IMap::MapScale which itself is a shortcut to IDisplayTransformation::ScaleRatio.
MapScale is the relationship between the dimensions of features on a map and the geographic objects they represent on the earth, commonly expressed as a fraction or a ratio. A MapScale of 1/100,000 or 1:100,000 means that one unit of measure on the map equals 100,000 of the same units on the earth. Some common scales are as follows:

public ITool getCurrentTool()
throws IOException,
AutomationException
The CurrentTool is the Tool used to interact will the MapControl's display. Always check if a tool is enabled before setting it to the CurrentTool property, otherwise a user will be able to use a tool that is actually disabled.
When the CurrentTool is set the following events occur:
Within an ITool implementation it is recommended that the ITool::Deactivate event returns true. This allows a 'new' CurrentTool to be set, and allows the release of the CurrentTool when an application is shutting down.

When the CurrentTool is set the following events occur:
Note that if the CurrentTool is set to Nothing, the ITool::Deactivate event is not triggered on the 'old' CurrentTool, instead it is forcibly removed. The same behaviour occurs if the PageLayoutControl is killed.

public void addLayer(ILayer layer,
int toIndex)
throws IOException,
AutomationException
When a Layer is added to the MapControl's layer collection and no index is specified, it is added to the beginning or top of the collection with an index of 0. The numeric index of any other layers in the layer collection increments by one.
When a Layer is added and an index is specified, the numeric index of any other layers in the layer collection will increment by one, except for those layers with an index less than the specified index. The index of these layers will remain the same.
The Layer at the beginning or top of the collection with an index of 0 will be drawn last, whilst the Layer at the bottom of the collection will be drawn first.

When LoadMXfile is used the user may be prompted for a password; refer to the tables below to determine when this may occur. Additionally, password prompts may be given if accessing MapDocuments using either the MapControl's PropertyPage, ArcMap or ArcReader; the tables also show in what circumstances this will occur.

public void refresh(int phase,
Object layerOrElement,
Object envelope)
throws IOException,
AutomationException
Use the Refresh method to redraw the display. If the Refresh method is used and no arguments are supplied the refresh is based upon the IActiveView::Refresh method.
In all other cases the refresh is based upon the IActiveView::PartialRefresh method. The Refresh method supports the esriViewDrawPhases given below:
0 :esriViewNone
1 :esriViewBackground
2 :esriViewGeography
4 :esriViewGeoSelection
8 :esriViewGraphics
16 :esriViewSelection
32 :esriViewForeground
If the Refresh method is used and no phase argument is supplied, but one of the other arguments is supplied then all phases will be refreshed and the phase value will be 65535. Always supply a phase whenever possible to increase efficiency.
Use the layerOrElement argument to refresh a particular layer or graphic element. Use the envelope argument to refresh only a particular region. For example, if a new graphic is added you may only want to refresh the area surrounding the graphic.
Use the TrackCancel object to set whether users can stop drawing processes by using the escape or spacebar keys or by clicking the mouse.
