InternetData
PowerScript function
Description
Processes the HTML data returned by a GetURL or PostURL function.
The Context object calls this function; you do not call this function
explicitly. Instead, you override this function in a customized descendant
of the InternetResult standard class user object.
Applies to
InternetResult objects

servicereference |

Blob containing the complete data requested by a GetURL or |
Return value
Integer.
Returns 1 if the function succeeds and -1 if an error occurs.
Usage
Override this function in a user object that is a descendant of
InternetResult. The overridden function must contain one argument of type
blob, which is passed by value. It should return an integer, processing
data as appropriate for the situation.
Do not call this function explicitly
Do not code calls to this function. The GetURL and PostURL
functions include an argument that references an instantiated
InternetResult descendant. When these functions complete, the Context
object calls the InternetData function, returning HTML in data.
Examples
This example shows code you might use in an overridden InternetData
function to display data from a GetURL function:
|
1 2 3 |
MessageBox("HTML from GetURL", & String(data, EncodingANSI!)) RETURN 1 |
The blob contains the actual data and is not Unicode encoded,
therefore you must use the EncodingANSI! argument of the String
function.
