[2005] determine crystal parameters

hey everyone quick and hopefully simple question and answer.

background:
we have a client that is going to be displaying CR's on the website. they want the users to have access to be able to enter the parameters. i know that i could allow CR to display the parameters automatically which is what I'd love to do but this is not the case or isn't how the client wants the system to work. so we've had to basically re-create the displaying of the parameters in a report so that some are auto filled and not editable while others are drop down list of values that can be accepted. i've managed to create everything so that it works this way, but there is one piece i have left and i'm not sure how this works.

i get a report and loop through all of the parameter and load the controls for the parameter. however it's loading way more controls then there are parameters in the report, that are visible. i've stepped through the code and have found that it's loading extra parameters that i'm not seeing in the main list of parameters. basically the parameters that are used to load data into the subreports. all of there additional parameters start with Pm- then the name of the parameter.

question:
first do there types of parameters ALWAYS start with Pm- if so then my question is answered. however if they don't is there a way to determine if it's not one of the main parameters in the main report?


thanks in advance for any info.
