NetOpenRemoteAccess (Function)

In french: NetOuvreAccèsDistant

Establishes a remote connection with a modem. This function can be used to handle the emails via the POP3 protocol on the remote server.

Note: Then, the remote connection can be closed by NetCloseRemoteAccess.

Example

// Starts the Internet connection on a PC
// The name of the connection to use is the one defined in the list of
// connections of the PC (control panel).
Report is int = NetOpenRemoteAccess("Connection_LiveBox")
IF Report = 0 THEN
...
NetCloseRemoteAccess()
ELSE
Error("Error during the connection", NetMsgError(Report))
END

// Open the connection on a Smartphone
sConnectionName is string
nCntReturn is int
// The name of the connection is given by the provider
sConnectionName = "Bouygues Internet"
// Open the connection
nCntReturn = NetOpenRemoteAccess(sConnectionName)
IF nCntReturn = 0 THEN
// Requested process
// ...
NetCloseRemoteAccess(sConnectionName)
ELSE
Error("Error during the connection:", NetMsgError(nCntReturn))
END

Syntax

<Result> = NetOpenRemoteAccess(<Access Name> [, <Password>] [, <Automatic closing>])

<Result>: Integer

0 if the connection was established,
an error code otherwise. This error code can be used by NetMsgError to know the error details and the corresponding message.

<Access Name>: Character string (with quotes)

Name of "Remote network access" connection defined in Windows. The list of remote accesses installed on a computer is returned by NetListRemoteAccess.
If the connection is already enabled (if it was opened manually or by another application), it is automatically retrieved.
In Windows Mobile 5 and 6, this parameter must correspond to an empty string (""): the connection is automatically found and used.

<Password>: Optional character string (with quotes)

Password associated with the connection.

<Automatic closing>: Optional boolean

True (default value): the connection will be automatically closed at the end of application or during the call to NetCloseRemoteAccess without parameter (valid for the last connection opened by NetOpenRemoteAccess).
False: the connection is not closed when the application is closed. Used, for example, to create an application that opens a connection. Similarly, NetCloseRemoteAccess without parameter will not close the connection. To close this connection, the access name must be passed in parameter.

Remarks

Connection for the remote network access

A connection for remote network access is created in the control panel of Windows. The following information is required to create the connection:

the caption of the connection (used by NetOpenRemoteAccess),
the phone number to dial,
the user login,
the modem, the protocol, etc.

This information is supplied by the provider.

When the connection is run via a double click performed on the corresponding icon, you have the ability to specify a password for this connection. This password can be stored in order to be used whenever this connection is started.

Various

Caution: The connection to a remote network can take quite a long time. The execution of the current application is locked during the entire duration of the connection.
A single connection can be opened at a given time.
We recommend that you check whether the connection operates properly in Windows before running NetOpenRemoteAccess.
