How to wait for ShellExecute to run?

by

There is a CodeProject article that shows how, by using ShellExecuteEx instead of ShellExecute:

SHELLEXECUTEINFO ShExecInfo = {0};
ShExecInfo.cbSize = sizeof(SHELLEXECUTEINFO);
ShExecInfo.fMask = SEE_MASK_NOCLOSEPROCESS;
ShExecInfo.hwnd = NULL;
ShExecInfo.lpVerb = NULL;
ShExecInfo.lpFile = "c:\\MyProgram.exe";        
ShExecInfo.lpParameters = "";   
ShExecInfo.lpDirectory = NULL;
ShExecInfo.nShow = SW_SHOW;
ShExecInfo.hInstApp = NULL; 
ShellExecuteEx(&ShExecInfo);
WaitForSingleObject(ShExecInfo.hProcess, INFINITE);
CloseHandle(ShExecInfo.hProcess);

The crucial point is the flag SEE_MASK_NOCLOSEPROCESS, which, as MSDN says

Use to indicate that the hProcess member receives the process handle. This handle is typically used to allow an application to find out when a process created with ShellExecuteEx terminates

Also, note that:

The calling application is responsible for closing the handle when it is no longer needed.
