You have to use GetLastError function to get API Error number

Declare Integer GetLastError In kernel32.dll as GetLastError

Declare Integer FormatMessage In kernel32.dll as FormatMessage ;
		Integer dwFlags, ;
		String @lpSource, ;
		Integer dwMessageId, ;
		Integer dwLanguageId, ;
		String @lpBuffer, ;
		Integer nSize, ;
		Integer Arguments

lcErrorTxt = ApiError()	
? lcErrorTxt 

.....
FUNCTION ApiError

Local lcErrBuffer, lcErrorMess, liNewErr, lnErrorCode
lcErrBuffer = REPL(CHR(0),1000)
lnErrorCode = GetLastError()
liNewErr = FormatMessage(0x1000;
 	,.NULL., lnErrorCode, 0, @lcErrBuffer,500,0)

lcErrorMess = Transform(lnErrorCode) + "    " + LEFT(lcErrBuffer, AT(CHR(0),lcErrBuffer)- 1 )

RETURN lcErrorMess
