Custom mouse icon used if MousePointer is 99.

Description

The MouseIcon property provides a custom icon that is used when the MousePointer property is set to esriPointerArrowHourglass (99).

Remarks

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.

Spatial reference of the Map.

Description

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.

getReferenceScale

public double getReferenceScale()
                         throws IOException,
                                AutomationException
Reference scale of the Map as a representative fraction.

Description

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.

Remarks

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.

Scale of the map as a representative fraction.

Description

This property is a shortcut to IMap::MapScale which itself is a shortcut to IDisplayTransformation::ScaleRatio.

Remarks

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()

                            AutomationException
Current active tool for the MapControl. Set to nothing to clear the tool.

Description

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.

Remarks

When the CurrentTool is set the following events occur:

  1. The ITool::Deactivate event is triggered on the 'old' CurrentTool if one was set. If this event returns false a trappable error ocurrs. If this event returns true the 'old' CurrentTool is removed and replaced.
  2. The ICommand::OnClick event is triggered on the 'new' CurrentTool and its cursor is picked up.

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.

Remarks

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.

If pCommand.Enabled = True Then

  Set PageLayoutControl1.CurrentTool = pCommand

End If

When the CurrentTool is set the following events occur:

  1. The ITool:: Deactivate event is triggered on the 'old' CurrentTool if one was set. If this event returns false a trappable error ocurrs. If this event returns true the 'old' CurrentTool is removed and replaced.
  2. The ICommand:: OnClick event is triggered on the 'new' CurrentTool and its cursor is picked up.

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.

                    AutomationException
Redraws the Map, optionally just redraw specified phases or envelope.

Description

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.

Remarks

Use the TrackCancel object to set whether users can stop drawing processes by using the escape or spacebar keys or by clicking the mouse.

When selecting features, Refresh must be called twice, once before and once after the selection operation.

                    throws IOException,
                           AutomationException
Checks the specified filename to see if it is a map document that can be loaded into the MapControl.

Description

Determines whether the specified map document (*.mxd, *.mxt, *.pmf) is a valid map document and can be loaded into the MapControl. The method verifies the file exists and verifies the file internals conform to an expected storage format. The method does not read and validate the entire contents of the file; use the LoadMxFile to do this.

Available with ArcGIS Engine.

Specified by:
checkMxFile in interface IMapControl2
Parameters:
fileName - The fileName (in)
Returns:
The result
Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

                         AutomationException
Opens a map document specified by the supplied filename and reads the maps into an array object.

Description

ReadMxMaps creates an array of Map objects from the specified Map Document (ArcMap document, ArcMap template or ArcReader document).

Remarks

When ReadMXMaps 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.

Description

This property is a shortcut to IDisplayTransformation::Rotation. The Rotation property controls the rotation of the display, and so the angle data appears inside the Map. The angle of the rotation is measured in degrees. Positive numbers rotate the display counter clockwise and negative numbers clockwise.
