Lotus C API里面有没有哪个函数可以得到邮件的附件名字的？

能不能给点注释？我看着满天的$,%都晕了。我是菜鸟没办法 :)
Peek和PeekString也是您自己写得函数吧？我在Lotus C API里面找不到它的帮助。
另外我粗略看了一下

PeekString fname$, p& + 38, nF&
m$ = m$ & Chr$(10) & "File: " & fname$

就是上面这2行得到文件名的吧？这样做似乎不行，您自己试验了吗？把两个同样名字的文件作为附件，然后用这样的方法得到的第二个文件名就变成“ATT*****”了。我觉得要判断个什么flag之类的，可是又没有资料。菜鸟继续求教。谢谢！

参考一些这个：

End Type

( Byval P As String, hDB As Long) As Integer
Declare Function NSFDbClose Lib wAPIModule Alias "NSFDbClose" _
( Byval hDB As Long) As Integer
Declare Function NSFNoteOpen Lib wAPIModule Alias "NSFNoteOpen" _
( Byval hDB As Long, Byval N As Long, Byval F As Integer, hNT As Long) As Integer
Declare Function NSFNoteClose Lib wAPIModule Alias "NSFNoteClose" _
( Byval hNT As Long) As Integer
Declare Function OSMemFree Lib wAPIModule Alias "OSMemFree" _

老大，加我QQ：95112013，注明：louts c api
指点我一下lotus c api,不甚感激。

现在我碰到的问题是：如果邮件附件有2个文件名一模一样，那么用这些API得到的文件名第一个正常，第二个变成了ATT*****，请问这种情况下应该怎么得到文件名？

[yaorong]

不要意思，公司里不能用QQ；
还有一个函数
Declare Function NSFItemInfoNext Lib wAPIModule Alias "NSFItemInfoNext" _
( Byval hNT As Long, Byval hP As Long, Byval B As Integer, Byval N As String, Byval nN As Integer, iB As BlockID, D As Integer, vB As BlockID, nV As Long) As Integer
