Did you know? You can generate VBScript or JScript code from a filter prototype by choosing File Menu\Export\Export VBScript or Export JScript. You can even generate a web page to run a filter from a friendly front-end.

For the TextPipe Engine, just substitute 'TextPipeEngine.Application' for 'TextPipe.Application'

Running an existing filter

This example simply loads and runs a predefined filter.

Dim TextPipeApp, Filter
Set
TextPipeApp = CreateObject("TextPipe.Application")
Set Filter = TextPipeApp.newWindow
Filter.openFilter( "C:\Program Files\TextPipe\EText\Centre text.fll" )
Filter.execute()
Set
Filter = Nothing
Set
TextPipeApp = Nothing

Processing a string in memory

This sample loads a predefined filter, then uses it to process and display a string.

Dim TextPipeApp, Filter
Set
TextPipeApp = CreateObject("TextPipe.Application")
Set Filter = TextPipeApp.newWindow
Filter.openFilter( "C:\Program Files\TextPipe\Fun\morse code.fll" )
msgbox "Converted text is: " & Filter.processString( "Hello from Mork" )
Set Filter = Nothing
Set
TextPipeApp = Nothing

Creating a filter on the fly

' addFile action - the action column
const afaAddTheFiles = 1

Dim
TextPipeApp, Filter
Set
TextPipeApp = CreateObject("TextPipe.Application")
Set Filter = TextPipeApp.newWindow
Filter.startFilters
Filter.addSimpleFilter( 42 )                     'randomize case
Filter.addLineNumberFilter( 20, 33, false, true, "%5.5d " )          'start number, increment
Filter.endFilters
Filter.addFile "c:\aemail\*.*", 3, afaAddTheFiles             '3 subfolders
Filter.execute()
Set
Filter = Nothing
Set
TextPipeApp = Nothing

A more complex example

Here's an example of TextPipe's powerful COM interface in action, using Windows Script. To use this example, save this text to a file (eg textpipe_example.vbs) and then double click it. You must also have Windows Script Host installed [more documentation]
