Determine whether parameter is dynamic or static?

Question

I'm having some challenges with applying connection information to my reports. I'm seeing that I need to use one method for reports that contain dynamic parameters, and another method for ones that do not. It's insane to me how difficult it's been to find a solid way to handle setting connection information, and there appears to be a million ways to do it, but I digress.
What's the best way to load a report and determine whether or not it contains parameters that are dynamic or not? Any advice would be appreciated!

Ok... I'll take you down the rabbit hole, which will probably slightly change the topic of this thread This all stems from a post I made back in 2011 which you and Don were active on:

I never did quite figure out the issue described in that thread, and finally began to tackle it again. My CR viewer needs to support reports that utilize ODBC (RDO) and OLE DB (ADO) connection types. As it turns out, reports utilizing OLE DB (ADO) connection types were actually working as expected, no login screen was being shown prior to the dynamic parameter being displayed, it was only reports utilizing the ODBC connection type. So I downloaded the "CodeBuilder-RasConnectionInfo" utility and worked with the code it generated, which looked like an entirely different method of setting the connection info. After using this new method, my ODBC based reports began to work just fine, whereas my OLE DB (ADO) reports were now displaying the logon prompt prior to displaying the dynamic parameters. The code I've been using all along has been working so well and is very trusted that thought one approach I would take is to detect if the crystal report contained dynamic parameters, and only use the new connection code if it did, otherwise it would revert back to what I was always using. I'm now changing my tune on this, and don't think that's the right approach. I'm actually comfortable with making the statement that my viewer only supports dynamic parameters when utilizing OLE DB (ADO) connection types. But just in case you are curious, here are the two blocks of code:
Here is what I was always using, where dynamic parameters show a logon prompt for ODBC connections types, but not OLE DB (ADO) connection types:

Here is what I used from the code generator, where dynamic parameters do not show a logon prompt for ODBC connection types, but do for OLE DB (ADO) connection types (In this example, there are minor changes to the code depending on whether the report utilizes ole db (ado) vs ODBC... The example here is for odbc

Ideally I would find one method that work work against both connection types and display dynamic parameters without the logon prompt, but I haven't found the answer yet.
I'm currently using 13.0.5.891 on the development system, and am testing the functionality against a 13.0.8 version of the runtimes. If you've got any thoughts or direction I might take, let me know.
