Visual Studio: Run C++ project Post-Build Event even if project is up-to-date

问题

In Visual Studio (2008) is it possible to force the Post-Build Event for a C++ project to run even if the project is up-to-date?

Specifically, I have a project which builds a COM in-process server DLL. The project has a post-build step which runs "regsvr32.exe $(TargetPath)". This runs fine on a "Rebuild", but runs on a "Build" only if changes have been made to the project's source.

If I do a "Build" without making any changes, Visual Studio simply reports that the project is up-to-date and does nothing - the Post-Build Event is not run. Is there any way that I can force the Event to run in this situation? This is necessary since although the DLL itself is up-to-date, the registration information may not be.

回答1:

You can use the Custom Build Step property page to set up a batch file to run. This runs if the File specified in the Outputs setting is not found, or is out-of-date. Simply specify some non-existent file there, and the custom build step will always run. It will run even if your project is up-to-date, since the Output file is never found.

Use this DisableFastUpToDateCheck

See an example:

<PropertyGroup>
    <PostBuildEvent>IF  EXIST C:\Projects\Copy_Files_To_Instance.ps1 ( powershell -file C:\Projects\Copy_Files_To_Instance.ps1)</PostBuildEvent>
    <DisableFastUpToDateCheck>true</DisableFastUpToDateCheck>

The registration information is determined largely by what's in the .rgs file. If that file changes the project will get built. I am not sure how else COM registration can change without making the project dirty. Do you mind providing more details about your particular situation?

In Visual Studio 2017 (perhaps other versions as well), for C# projects (haven't checked for C++ projects per OP's actual question) there is an option for "Run the post-build event:", and one option is "Always", which will run the Post-Build even if nothing has changed, rather than simply reporting that the project is up to date:
