Possible to get names of class/modules at run-time?

edb · **Posted:** Fri May 24, 2013 10:04 pm

Add a couple of custom modules or classes to a project, and name them. Is there a way to retrieve the names of these classes/modules within an application/project at run-time using code?

Yes, using the Introspection class. There is an example in the documentation.

Thanks, simulanics. I figured introspection is the place to go for this; however, I have no idea what I'm doing. I can find ways to pull method names, etc. out of a class that is already known, but I can't find a way to pull the class names themselves from the app. I'll re-read the documentation and see what I can figure out. Again, I appreciate the assistance.

put App (without quotes) in place of the control/class name in the Introspection Methods parameter...

Dim myMethods() As Introspection.MethodInfo = Introspection.GetType(App).GetMethods
For i As Integer = 0 To myMethods.Ubound
  msgbox myMethods(i).Name
Next

hope that helps...

Tried that already, and unfortunately the names of my classes/modules don't appear in the return array.

If I understand correctly, you want to use the "runtime" function:
http://docs.realsoftware.com/index.php/Runtime

With the introspection system "GetType" method:
http://docs.realsoftware.com/index.php/ ... on.GetType

Then you should be able to go over all the runtime objects and check the various Type properties (such as fullname):
http://docs.realsoftware.com/index.php/TypeInfo

That dont seem to work either... I was reading that custom modules and classes are handled differently than the built-in ones by the compiler...so it's as if they don't exist...I'm sure there has to be a way though...the method you mentioned above would be the following:

Dim myDbMethods() As Introspection.MethodInfo
Dim o as Runtime.ObjectIterator=Runtime.IterateObjects
While o.MoveNext
  myDbMethods() = Introspection.GetType(o.current).GetMethods
  For i As Integer = 0 To myDbMethods.Ubound
    Listbox1.AddRow(myDbMethods(i).Name)
  Next

For my project over at www.simscript.org I had to fan-angle a bunch of API's to peek for method names. SimScript is a plugin engine to compile plugins (like applications) for Xojo/RS..they can have interfaces, access the parent app's properties, methods, etc...and pass information back and forth between the loaded plugin and the Xojo/RS application and/or the Plugin Designer debugger. :-)

Unfortunately that is proprietary code..but there is demos and source if you're interested. There has to be a "purely" Xojo/RS method to obtain all the methods from custom classes/modules...I've search almost a year and still no answer so the previously mentioned project required some 'creativity.'

Classes yes
Modules no - at least not without using unsupported hackery

You can't find a list of all classes in your RB app.

Would it be possible to use IDE Scripting to auto-generate this info?

I've done this before by saving as XML, processing that and dragging a generated class file back into the project. Clumsy but the only way without hackery or possibly IDE Scripting.

I'll confess I'm VERY curious how you'd even make use of this or what the intent is

You can save your project as an XML document and get grab them from there for purposes such as documenting them but as norm said, without unsupported "Hackery" it is not possible.

:) I don't really remember. I think it was for a graph editor where the user can add nodes for any class available to the app, including those in the RB API, and rather than manually maintain the functions for listing and constructing classes it seemed saner to auto-generate. Or maybe it was for an RBScript app; can't find the projects atm.
