Then check the history of this project. Maybe it never worked (recently). Anyway, take out some useful part and see if you can compile that. Never met software where I couldn't find something to remove / refactor (or totally rewrite). If you don't understand it, you probably don't need it.

This has nothing to do with Managed C++/CLI. Please use the correct forum for your questions. You already have a question in the MFC forum. And the answer to your question is simply to use a timer as described at SetTimer function (winuser.h) - Win32 apps | Microsoft Docs[^].

I've gotten further. It looks like you need to hand-edit the .vcxproj file and add the proper framework references. For example: Alas, now I can compile but am left with unhelpful link errors. 1>MSVCMRTD_netcore.LIB(mstartup.obj) : error LNK2022: metadata operation failed (80131195) : 1>MSVCMRTD_netcore.LIB(mstartup.obj) : error LNK2022: metadata operation failed (80131195) : 1>LINK : fatal error LNK1255: link failed because of metadata errors

You already [osted this question at Alternate swapping of boundary elements of square matrix[^]. Please do not cross post.

Posting the same question over and over is frowned upon. The most likely cause of unresolved external references is that you have not included a reference to a necessary DLL. Open the project properties, go to Linker, Input and add the name(s) of the required LIB file(s). The difficult we do right away... ...the impossible takes slightly longer.

It has already been suggested to you that you need to provide more information. We have no idea what your problem is and have no way of guessing.

It is most unlikely that the poster of this question is still waiting for an answer nearly eleven years later.

Look at the question. This is a basic classroom assignment for people with no programming background.

Have a look at the [ShellExecuteA function (shellapi.h) - Win32 apps | Microsoft Docs](https://docs.microsoft.com/en-us/windows/win32/api/shellapi/nf-shellapi-shellexecutea) : its fourth parameter (LPCSTR lpParameters) is what you are looking for.
