谁有TAPI.pas，能否发一份给我,谢谢！(100分)

哪位朋友手头有TAPI.pas，能否发一份给我？baeyk@sohu.com，急！
如果有例程一并发来更好，如果能告诉我下载处亦可

给你一个例程，先看看吧！

TAPIERROR_FORMATMESSAGE - macro to convert a TAPI error constant
into a constant that FormatMessage will accept

TAPIERR : Negative numbers and 0
Map to : strip off high WORD
Example: 0xFFFFFFFF (-1) becomes 0x0000FFFF
LINEERR : Start at 0x80000000
Map to : strip off 0x80000000 and add 0xE000
Example: 0x80000004 becomes 0x0000E004
PHONEERR: Start at 0x90000000
Map to : strip off 0x90000000 and add 0xF000
Example: 0x9000000A becomes 0x0000F00A

pseudocode:

if (__ErrCode__ is a TAPIERR)
strip off high word

else if (__ErrCode__ is a PHONEERR)
strip off 0x90000000
add 0xE000

else
strip off 0x80000000
add 0xF000
