DataSourceComponent Class

Uses

System.ComponentModel.Component

Description

The DataSourceComponentClass provides properties and methods that allow the user to interact with the data source. A description of how to use the data source can be found here. A description of the contents of the data source can be found here.

Public Constructors

Constructor	Description
DataSourceComponent	Creates a new instance of the DataSourceComponent class

Public Properties

Property	Description
CalculatedSignature	The CalculatedSignature Property returns the signature calculated from the current contents of the base data source file.
CustomFileName	The CustomFileName property returns the path and name of the custom data source file that is currently loaded into the DataSourceComponenet.
DefaultIssuer	Gets or sets the default issuer value for use with Get/Put/Remove methods
Editable	A boolean value that indicates if the data source can be modified
FailOnInvalidSig	The FailOnInvalidSig property indicates or sets whether we should throw an exception during the LoadFile call if the base data source file has been manually edited
FileName	The path and file name of the data source currently loaded into this object
HasExpiry	Indicates if the license used for GeoCalcNET has an expiration data
IgnoreEnvelope	Indicates if all Envelopes should always return true for InBounds
IsLoaded	A boolean value that indicates if a data source is currently loaded
IsSignatureValid	The IsSignatureValid Property indicates if the base data source file has been manually edited since the last time it was saved.
IsTrial	Indicates if this is an evaluation version of GeoCalcNET
Licensed	Indicates if this is a licensed version of GeoCalcNET
SignatureFromFile	The SignatureFromFile property returns the signature stored in the base data source file.
TimeToNag	Indicates if it is time to remind the user that this is an evaluation version of GeoCalcNET
WKTForceMatch	Indicates if GeoCalc should try to find an existing CoordSys that matches the WKT when importing a CoordSys from WKT
