How to avoid

Question

I need to launch another application in current process which already called SetDllDirectory.As described here

child process will inherit the directory used by the calling of SetDllDirectory in parent process. My question is how avoid this? It seems that CreateProcess and ShellExecute both have this problem.By the way, I could not remove the calling of SetDllDirectory in parent process or add a calling of SetDllDirectory in child process.

Hello @Fan Young ,

Welcome to Microsoft Q&A!

According to the document,

For Win32 processes that are not running a packaged or protected process, calling this function will also affect the DLL search order of the children processes started from the process that has called the function.

This is by design. If you want to switch DLL directory in the win32 child process, you can only call SetDllDirectory again.

"By the way, I could not remove the calling of SetDllDirectory in parent process or add a calling of SetDllDirectory in child process."

It is recommended to use AddDllDirectory to add multiple DLL directories.

Thank you.
