CloseSource Method




ImageGear.Twain Assembly > ImageGear.TWAIN Namespace > ImGearTWAIN Class : CloseSource Method
This method closes the currently opened Data Source Manager as well as any currently open Data Sources.
Syntax
'Declaration
 
Public Sub CloseSource() 
'Usage
 
Dim instance As ImGearTWAIN
 
instance.CloseSource()
public void CloseSource()
public: void CloseSource(); 
public:
void CloseSource(); 
Exceptions
ExceptionDescription
Thrown when this method is called but there is not an open connection with the Data Source Manager.
Remarks

When an application is finished with a Data Source, it must formally close the session between them using this method. This is necessary in case the Data Source only supports connection with a single application (many desktop scanners will behave this way). A Data Source such as this cannot be accessed by other applications until its current session is terminated.
