Hi,
I want to make it possible for the user to create an unlimited
(perhaps up to ten in practice :-) ) number of dialog boxes/windows at
runtime depending on what the user selects in the main gui. It is
meant to be a lot of dialog modules each containing a specific set of
adjustable parameters that affects the processing in the main gui. The
problem is I don't know how many dialog are going to be created at
compile time.
Because of the ways I want to use the code it is very important for me
that I do not just hardcode ten different resource ids in the resource
file. I want to create the dialog ids, set their positions, styles,
sizes and fill controls into them at runtime.

I have made this class:

class AM3DParamInterfaceWindow : public CDialog

and in the constructor I try to create the dialog:

this->Create(dialogId, pParent); //CWnd* pParent is a pointer to the
parent window

The problem is that "dialogId" apparently has to exist in the ".rc"
file otherwise I get an error saying that the resource can not be
found. I also think the ids of the dialogs have to be different in
order not to mix up things.

I hope you understand what I want to accomplish otherwise I will try
to explain it better.

Have you considered using just one dialog template, with no controls on it?
That would be much easier.

Are you a beginner with MFC? Your concept sounds like a poor solution and
will be extremely difficult to implement. But you haven't explained your
real problem so I can't suggest a better approach. To do what you think you
want to do you will have to create the dialogs with the
CreateDialogIndirectParam API, which is not part of MFC. But MFC itself
uses this API so you can get some hints how to integrate it with CDialog by
studying the MFC source code.
