Funciones en power builder
Me pregunto si puedes ayudarme con unos problemitas que tengo. Resulta que estoy tratando de utilizar unas funciones de la librería Kernel32, pero tengo varios errores que no se en que consisten, creo que es problema de llamado o algo así, me tomo el atrevimiento de enviarte el código de lo que he avanzado para ver si puedes darme alguna sugerencia al respecto, te agradezco de antemano y espero una pronta respuesta. Gracias.
Protoripos de las funciones:
Locales:
Function ulong FindFirstFile (string lpFileName, ref WIN32_FIND_DATAA
lpFindFileData) LIBRARY "KERNEL32.DLL"
Function boolean FileTimeToSystemTime (ref FILETIME lpFileTime, ref SYSTEMTIME lpSystemTime)
LIBRARY "KERNEL32.DLL"
Function boolean FileTimeToLocalFileTime (ref FILETIME lpFileTime, ref FILETIME lpLocalFileTime)
LIBRARY "KERNEL32.DLL"
Externas:
FUNCTION uint FindWindowA (long classname, string windowname) LIBRARY "user32.dll"
Estructuras utilizadas:
