Ayuda creacion RunPE VB6

Bueno, estoi intentando aprender como trabaja el loader de windows y me e puesto a hacer un runPE, viendo como funcionan otros y tal despues de haber leido varias veces sobre el formato PE, pero tengo problemas, no me funciona correctamente el api NtUnmapViewOfSection ni VirtualAllocEx y nose porque no funcionan bien... el código que tengo es el siguiente:
