Notes中幾個處理多值域的通用函式

1.查詢出查詢內容在多值域中的索引值

getitemindex(網域名稱，域值，文件)

public function getitemindex(byval fieldname as string, byval itemval as object, 

byval doctt as notesdocument) as integer
dim i as integer
dim j as integer
dim item as notesitem
item = doctt.getfirstitem(fieldname)
j = ubound(item.values)
for i = 0 to j
if itemval = item.values(i) then
getitemindex = i
exit function
end if
next
getitemindex = -1
end function

2.刪除多值域中的資料

delitemvalues(多值網域名稱,更改的索引值,所在文件物件)

public sub delitemvalues(byval fieldname as string, byval index as integer, byval doctt as notesdocument)

dim i as integer
dim temp() as object
dim item as notesitem
item = doctt.getfirstitem(fieldname)
dim j as integer
j = ubound(item.values)
'-----------
if j = 0 then
'當j為0時，即僅有乙個值，給予空值即可
call doctt.replaceitemvalue(fieldname, "")
exit sub
end if
'------------
if trim(item.values(0)) = "" 
then
index = j
end if
if index > j then
'仍然做為最後乙個資料加入 
j = j + 1 '索引位僅增加1
index = j '重定義索引位，防止超出範圍
end if
redim temp(j-1) as variant 
'重定義陣列 
for i = 0 to index - 1
temp(i) = item.values(i)
next
for i = index to j - 1
temp(i) = item.values(i + 1)
next
call doctt.replaceitemvalue(fieldname, temp)
'end if
'end if
end sub

3.更改多值域中的資料

edititemvalues(多值網域名稱,更改的索引值,更改的內容,所在文件物件)

public sub edititemvalues(byval fieldname as string, byval index as integer, byval itemval as object, 

byval doctt as notesdocument)
dim i as integer
dim temp() as object
dim item as notesitem
item = doctt.getfirstitem(fieldname)
dim j as integer
j = ubound(item.values)
if trim(item.values(0)) = "" 
then
index = j
end if
if index > j then
'仍然做為最後乙個資料加入 
j = j + 1 '索引位僅增加1
index = j '重定義索引位，防止超出範圍
end if
redim temp(j) as variant 
'重定義陣列
for i = 0 to j
if i = index then
temp(i) = itemval
else
temp(i) = item.values(i)
end if
next
call doctt.replaceitemvalue(fieldname, temp)
'end if
'end if
end sub
