How can I launch a C++ native application from a Windows Service main function (the application interacts with the console)? -

-

i'm using _spawnl() function launching c++ native application main service function (svcmain), application never gets run.

is there trick launch applications interacts user?

it runs, cannot see it. have use createprocessasuser() instead of _spawnl() new process runs in specific user's session, not in service's own session. in vista , later, services run in own isolated sessions (session 0 isolation), users cannot see or interact with. common solution use wtsgetactiveconsolesessionid() and/or wtsenumeratesessions() find desired user session, use wtsqueryusertoken() token hanlde can used createenvironmentblock() , createprocessasuser(). also, when providing startupinfo createprocessasuser(), set lpdesktop field "winsta0\\default" (the user's default desktop can interact after logging in).

mysql - FireDac error 314 - but DLLs are in program directory -

i getting when trying access mysql database : [firedac][phys][mysql]-314. cannot load vendor library [libmysql.dll or libmysqlld.dll] this did not happen (unchanged) code, however, have upgraded windows 10 , had reinstall delphi xe8, system configuration matter. in order try solve problem, copied both of files c:\windows\sysytem32. when did not seem work, copied them \win32\debug, generated .exe resides. i imagine doing rather stupid, can't see what. the proper solution place driver file (eg., libmysql.dll ) in application's folder, or place installation location in fddrivers.ini file: [mysql] vendor=<folder>\libmysql.dll (recent versions of documentation seem use vendorlib instead of vendor in ini file.) see rad studio documentation topics configuring drivers (firedac) , connect mysql server (firedac) more information.
