Why Web.Link UDF needs an unexpected click

[Kittychen]

1. example pfcUDFCreateExamples.html comes with Creo at "...\Common Files\M230\weblink\weblinkexamples" 

2. It can work

but needs a click to specify the csys to place the UDF <--- problem !!! csys is given whey still needs a click? 

find the source code and necessary .prt .gph to see the symptom.

Thank you very much!!!

I found the answer myself in the manual: 

The method pfcUDFReference.Create() is a static method creating a UDFReference object. It accepts the following parameters:

•

PromptForReference—The prompt defined for this reference when the UDF was originally set up. It indicates which reference this structure is providing. If you get the prompt wrong, pfcSolid.CreateUDFGroup() will not recognize it and prompts the user for the reference in the usual way.

I don't understand what does it mean. Sounds like the 'prompt' is a password the caller must provide it correctly or the given reference will be ignored and thus the function waits for a mouse click instead. That's a mistake-proof I guess.

This is the method for Jlink while you create UDF, all you need to do is to constructure the compact class (this kind of class just contains the dataobject for the other static mehod especially the static method to create some class )UDFGroupCreateInstructions to be passed to the method

CreateUDFGroup

(UDFGroupCreateInstructions Instructions)

weblink is the same as this! however,if you still need the method for weblink ,pls send me a message
