Deployment Tools Foundation Database Constructor (filePath)

Opens an existing database in read-only mode.

Declaration Syntax

Visual Basic

Visual C++

public Database(
	string filePath
)

Public Sub New ( 
	filePath As String
)

public:
Database(
	String^ filePath
)

Parameters

filePath (String): Path to the database file.

Remarks

Because this constructor initiates database access, it cannot be used with a running installation.

The Database object should be Close()()()()d after use. It is best that the handle be closed manually as soon as it is no longer needed, as leaving lots of unused handles open can degrade performance.

Win32 MSI API: MsiOpenDatabase

Exceptions

Exception	Condition
InstallerException	the database could not be created/opened
