ValidateId Method  
 

Check an application identifier to ensure it is valid and exists.

Syntax

object.ValidateId ( AppId )

Parameters

AppId
A string which specifies the application ID to be validated. If the application ID is a zero-length string or contains illegal characters, the method will fail.

Return Value

A value of True is returned if the application ID is valid. Otherwise, a value of False is returned and the LastError property will return the specific cause of the failure.

Remarks

The ValidateId method is used to determine if the specified application identifier is valid and has been previously registered using the RegisterId method. The ID must only consist of ASCII letters, numbers, the period and underscore character. Whitespace characters and non-ASCII Unicode characters are not permitted. The maximum length of an application ID string is 63 characters.
