Can't locate wxWidgets app with EnumWindows()/EnumDesktopWindows()

[bsenftner]

I have a wxWidgets application I want to periodically check is running. I believe the method to do this on Windows is with a Service.

I am using a minimally modified version of the "A basic Windows service in C++" sample, located here: https://code.msdn.microsoft.com/windows ... e-cacf4948

The Service compiles and runs fine. At this point, the Service is just the Service skeleton provided by that sample. I'm trying to add logic that locates my wxWidgets application, but am having zero luck...

I have tried both EnumWindows() and EnumDesktopWindows() with different Service Users ("LocalSystem", "NT AUTHORITY\\LocalService", & my own account) and in every case a series of window names are generated, but no where near the actual number of desktop windows I have, and never my wxWidgets application.

I actually have one other wxWidgets app running, multiple Google Chrome browser windows, multiple ms windows cmd shells, Visual Studio, Outlook, Skype, the Event Lister, and Notepad++ (not to mention 6 different File Browser windows) and NONE of these show up in any cases of my Service's call to EnumWindows() or EnumDesktopWindows().

When trying with Service Users "LocalSystem" or "NT AUTHORITY\\LocalService" I do set the Service to interact with the desktop. Makes no difference...

I have some log messages:

Just entered wmain.

CServiceBase::Start: I think we're running!!!

Where you see "window title:" that is the output from EnumDesktopWindows(). I get the same listing from EnumWindows(). Of those 8 "windows" listed, none are my desktop applications. So, I'm confused...

Anyone have any ideas here?

First of all: Try the code from inside a "normal" application instead of a service. Just to make sure that that's not the reason.

I don't know why you don't see the wx windows (maybe you should have posted the code for the searching), but maybe getting a list of running processes does also work for your purpose:
