如何解決“非法引用null"值的錯(cuò)誤

nmysc

我做了一個(gè)小程序，準(zhǔn)備向WORD的表中填加數(shù)據(jù)庫中的字段值，但是出現(xiàn)了一個(gè)小問題，當(dāng)字有數(shù)據(jù)時(shí)，沒有問題，但是當(dāng)沒有數(shù)據(jù)是提示我“非法引用NULL值”，我應(yīng)該如何處理，就象郵件合并是，沒數(shù)據(jù)，只顯示為空的單元格。因?yàn)樽侄魏芏�，不能每個(gè)都去判斷是否為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，你可以用一個(gè)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?yàn)?quot;"與Null值連接時(shí)值為"","" 與其它值連接時(shí)值不變.

這可是我的妙招呵!
