如何解决“非法引用null"值的错误

nmysc

我做了一个小程序，准备向WORD的表中填加数据库中的字段值，但是出现了一个小问题，当字有数据时，没有问题，但是当没有数据是提示我“非法引用NULL值”，我应该如何处理，就象邮件合并是，没数据，只显示为空的单元格。因为字段很多，不能每个都去判断是否为NULL



Sub startword()

On Error GoTo err_startword
Dim wrd As New Word.Application, isrunning As Boolean
Dim tableNew As Table, tableNew1 As Table

Dim dbMyDB As Database, rst As Recordset, rst1 As Recordset


isrunning = True
wrd.Documents.Open fileName:="D:\Documents and Settings\ysc\My Documents\djb"
wrd.Visible = True
Set tableNew = ActiveDocument.Tables(1)
Set dbMyDB = CurrentDb
Set rst = dbMyDB.OpenRecordset("jijan1", dbOpenSnapshot)
rst.MoveFirst


With tableNew
    .Cell(1, 2).Range.Text = rst("01")
    .Cell(1, 2).FitText = True
    .Cell(1, 4).Range.Text = rst("02")
    End With


If isrunning = False Then
wrd.Quit
End If
Exit Sub
err_startword:
If Err.Number = 429 Then
Set wrd = CreateObject("word.application")
isrunning = True
Resume Next
Else
MsgBox Err.Number & "" & Err.Description
Exit Sub
End If
End Sub

空值，你可以用一个空格代替。

wrd.Visible = True
Set tableNew = ActiveDocument.Tables(1)
Set dbMyDB = CurrentDb
Set rst = dbMyDB.OpenRecordset("jijan1", dbOpenSnapshot)
rst.MoveFirst

做以下的修改:
.Cell(1, 2).Range.Text = "" & rst("01")
.Cell(1, 2).FitText = True
.Cell(1, 4).Range.Text = "" & rst("02")

因为""与Null值连接时值为"","" 与其它值连接时值不变.

这可是我的妙招呵!
