OpenDatabase Method Prompts for User Input (141826)

In Microsoft Excel, when you run a macro that uses the OpenDatabase
method to open a database, you may be prompted for information even
though the Source argument includes a complete connection string to the
data source you are using.
CAUSE
If either the Exclusive (called to Options in version 97) and Read-only
arguments are omitted, and the Source argument is included, you will be
prompted for any information needed to connect to a data source. The
following example illustrates this behavior.
Microsoft provides programming examples for illustration only, without warranty either expressed or implied. This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements.
Before you run the macro, you must create a reference to the DAO Object
Library. To do this, activate a module sheet, click References on the
Tools menu and select Microsoft DAO 3.5 Object Library (3.0 Object
Library in version 7.0).
Sub OpenDB()
Dim db As Database
' Open a connection to the SQL Server data source called
MySQLServer
Set db = OpenDatabase("", , , "ODBC;DSN=MySQLServer;" _
& "UID=user1;PWD=pass;DATABASE=Master")
End Sub
In this example, all necessary options to make a connection to the data
source called MySQLServer have been specified. However, because the
Exclusive (or Options) and Read-only options are missing, you will be
prompted for the connection information anyway.
RESOLUTION
When you use the Source argument of the OpenDatabase method, specify a
value of True or False for both the Exclusive (Options) and Read-only
arguments.
The example above would then read as:
Sub OpenDB()
Dim db As Database
' Open a connection to the SQL Server data source called MySQLServer
Set db = OpenDatabase("",False ,False , "ODBC;DSN=MySQLServer;" _
& "UID=user1;PWD=pass;DATABASE=Master")
End Sub
STATUS
This behavior is by design.
