public class IMapControlDefaultProxy
Provides access to members that control the MapControl.
The IMapControlDefault interface is the default dispatch interface that most development environments will automatically expose. For example, placing the MapControl in a container will typically generate an object called MapControl1. The properties and methods available directly on this object correspond to this interface, together with container specific properties and methods.
The IMapControlDefault interface is a 'pure' dispatch interface, so can be extended with new properties and methods at future releases of ArcGIS. The methods and properties are identical to the highest numbered main interface on the MapControl. For example, IMapControlDefault is equivalent to IMapControl4, but at future releases this could become IMapControl5. By using the IMapControlDefault interface you are guaranteed to always have access to the latest MapControl.
There is a small performance overhead in making calls through to a pure dispatch interface, but to avoid this you can QI to a specific interface. In some development environments it is not possible to QI directly on the control to other COM interfaces, because the control is contained within a wrapper object. Use the Object property to get the real control before performing the QI.

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.
getCurrentTool in interface IMapControlDefaultIOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
public void setCurrentToolByRef(ITool rhs1)
throws IOException,
AutomationException

public void suppressResizeDrawing(boolean suppressResize,
int resizeHWnd)
throws IOException,
AutomationException
If the MapControl contains a lot of data, redrawing this data during a resize event can be costly. To increase performance you can suppress the data redraw until the resizing is complete with the SuppressResizeDrawing method. During the resize a stretched bitmap will be drawn instead.
Passing the suppressResize value sets the IScreenDisplay::SuppressResize property on the ActiveView. Pass True to suppress normal drawing and draw a stretched bitmap when a resize event begins. During the resize the data is not refereshed and the captured image is stretched. As such, the image can appear pixelated when a small display area is resized to a large display area. Pass False to resume normal drawing when a resize event ends.
In development environments that do not trap the beginning and end of a resize event, the MapControl can 'watch' the hwnd supplied to the SuppressResizeDrawing method. When a form or container starts resizing the WM_ENTERSIZEMOVE windows messge is sent and the MapControl will set suppressResize to True. When windows sends the WM_EXITSIZEMOVE message the form or container is released from resizing and the the MapControl will set suppressResize to False. Pass the hwnd of the form or container to the SuppressResizeDrawing method when the form or container is initialized. Passing an hwnd of 0 will stop the MapControl watching the hwnd.

public int getKeyIntercept()
throws IOException,
AutomationException
Returns or sets keys on the keyboard that will be intercepted by the MapControl, triggering the OnKeyDown and OnKeyUp events when pressed. These keys are often hidden from the MapControl by the development environment container. By default the KeyIntercept is set to esriKeyInterceptNone.
Many development environment containers use the up, down, left and right arrow keys to change control focus on a form. These keys can also be useful for navigating around the display. To intercept the arrow keys and the Tab key combine the enum values using a logical OR operation (esriKeyInterceptArrowKeys OR esriKeyInterceptTabKey, which is 1 OR 4 = 5).

Most development environments use the 'Arrow' keys to switch focus between the controls embedded in a form or container. In such environments the MapControl will not by default receive the 'Arrow' keys to pan the display. To ensure 'Arrow' keys are received by the MapControl the KeyIntercept property must be set to intercept the 'Arrow' keys in order to pan the display when AutoKeyboardScrolling is true.
