Visual Studio pre-build event; Checking exit code for each event

events, exit-code, pre-build-event, visual-studio

Solution

I think yuou can do as follows:

run command 1
if ERRORLEVEL 1 (
    exit /b 1
    )
run command 2

Problem

I have a solution with multiple projects. One project only needs to build if both two events, in the pre-build event, exit with error code 0. So I thought I could do the following: "C:\Path\To\Binary1.exe" & "C:\path\to\binary2.exe" In my test scenario something goes wrong so Binary1.exe exits with a non-zero value. But visual studio goes on building the project anyway. When I run the pre-build event commandline in cmd and echo %errorlevel% I see the exit code being non-zero. When I only put "C:\Path\To\Binary1.exe" in the pre-build event, the build is stopped and en error is shown in the `Error List` window of Visual Studio. I am definitely sure that Binary1.exe is exiting with a non-zero value as its also shows a messagebox prior to exit. I can think of one solution. Binary1.exe calling Binary2.exe and exiting with a non-zero exit code when Binary2.exe exits with a non-zero exit code. But that is not really a flexible solution. To summarize: How can I run multiple pre-build events and stop buidling when one of the commands returns a non-zero value?
