Description

TConnectMode values indicate the persimissions available to a connection.

Use TConnectMode values to determine the permissions available to a connection and thus what type of data operations can be performed through that connection.

TConnectMode constants correspond directly to the ConnectModeEnum values for the Mode property of the ADO Connection object. The TConnectMode constants have the same effect on a TADOConnection component as the ConnectModeEnum values have on the Connection object. These values are discussed in the Microsoft Data Access SDK help.

TConnectMode consists of the eight constants summarized in the following table:

Connect Mode	Meaning
cmUnknown	The permissions have not yet been set for the connection or cannot be determined.
cmRead	Read-only permissions are available to the connection.
cmWrite	Write-only permissions are available to the connection.
cmReadWrite	Read/write permissions are available to the connection.
cmShareDenyRead	Prevents others from opening connections with read permissions.
cmShareDenyWrite	Prevents others from opening connection with write permissions.
cmShareExclusive	Prevents others from opening connection.
cmShareDenyNone	Prevents others from opening connection with any permissions.
