ActiveView Control Events
BeforeConnection Event
This event occurs before a connection to the Historian Server is attempted.
This allows the programmer to alter the user name and password so that
logging into the Server is not apparent to the user. When the call returns,
connection is attempted.
Format
BeforeConnection (myParam as BCParam)
Example
The following is an example of using JavaScript to use the security events:
<html>
<head>
<script language = "VBScript">
Sub window_onLoad()
Pbd1.DisplayURL = "<MyDisplayURL>"
End Sub
</script>
<script id = "clientEventHandlersJS" language = "javascript">
function Pbd1_BeforeConnection(pParam) {
pParam.Username = "MyUserName";
pParam.Password = "MyPassword";
}
</script>
<script language = "JavaScript"
for = "pbd1"
event = "BeforeConnection(pParam)">
Pbd1_BeforeConnection(pParam)
</script>
</head>
<body>
