I would like a procedure to select (simulate a mouse click on) an item in the right-click popup menu of an arbitrary (i.e. third-party) icon (application) in the system tray.

I imagine the parameters would be something like

Blah(TrayIconHandle: THandle; MenuCaption: String);

or

Blah(TrayApplicationEXEName: String; MenuCaption: String);

or

Blah(WindowClassName: String; MenuCaption: String);

...or something similar.

It works more different than you think, unfortunately... I've done quite a few interesting things with trayicon applications and often use the raw API functions to make them do what I want them to do. So let's explain how the mechanism works...

Behind a treeview there's a messageloop that is responding to messages send to it. This messageloop is linked to a popup menu and this popup menu is just sending messages to the message loop. So you (right) click on the icon and it gets a message to show the popup menu. Then you click on a menuitem and a message is posted to execute some action.

A messageloop is represented by a handle of a visible or non-visible window. This window captures the GUI related messages. So you need to know to which handle you have to send the messages. The application can contain multiple messageloops each in their own thread so it's not easy to determine to which messageloop you have to post a new message. (Or which window) And you need to know which message for the menu-item you want to post. (You can actually skipping the right-click here, btw.)

It's not an easy task but a tool like winspy or spy++ can show you the messages that are sent around and to which messageloops they are sent.

Unfortunately, there are many programs called "winspy", and I'm having difficulty filtering the Google search results down to the appropriate tool.  Can you provide a URL?

Try D:\Borland\Delphi5\Bin\ws32.exe or wherever else you have Delphi installed. Delphi has a tool called WinSight that's doing something similar to WinSpy and those tools. ;-)
And to be honest, there are hundreds of these kinds of message spy tools. They're not too hard to make yourself once you're familiar with Windows hooks...
