筆者的解決方法是利用app.path 來(lái)解決這個(gè)問(wèn)題。
一、用data控件進(jìn)行數(shù)據(jù)庫(kù)鏈接，可以這樣：
在form_load()過(guò)程中放入：
private form_load()
Dim str As String '定義
str = App.Path
If Right(str, 1) <> "" Then
str = str + ""
End If
data1.databasename=str & "數(shù)據(jù)庫(kù)名"
data1.recordsource="數(shù)據(jù)表名"
data1.refresh
sub end
這幾句話的意為，打開(kāi)當(dāng)前程序運(yùn)行的目錄下的數(shù)據(jù)庫(kù)。
你只要保證你的數(shù)據(jù)庫(kù)在你程序所在的目錄之下就行了。
二、利用adodc（ADO Data Control)進(jìn)行數(shù)據(jù)庫(kù)鏈接：
private form_load ()
Dim str As String '定義
str = App.Path
If Right(str, 1) <> "" Then
str = str + ""
End If
str = "Provider=Microsoft.Jet.OLEDB.3.51;Persist Security Info=False;Data Source=" & str & " sl.mdb"
Adodc1.ConnectionString = str
Adodc1.CommandType = adCmdText
Adodc1.RecordSource = "select * from table3"
Adodc1.Refresh
end sub
三、利用DataEnvironment進(jìn)行數(shù)據(jù)庫(kù)鏈接
可在過(guò)程中放入：
On Error Resume Next
If DataEnvironment1.rsCommand1.State <> adStateClosed Then
DataEnvironment1.rsCommand1.Close '如果打開(kāi)，則關(guān)閉
End If
'i = InputBox("請(qǐng)輸入友人編號(hào):", "輸入")
'If i = "" Then Exit Sub
DataEnvironment1.Connection1.Open App.Path & "userdatabase sl.mdb"
DataEnvironment1.rsCommand1.Open "select * from table3 where 編號(hào)='" & i & "'"
'Set DataReport2.DataSource = DataEnvironment1
'DataReport2.DataMember = "command1"
'DataReport2.show
end sub
四、利用ADO(ActiveX Data Objects)進(jìn)行編程：
建立連接：
dim conn as new adodb.connection
dim rs as new adodb.recordset
dim str
str = App.Path
If Right(str, 1) <> "" Then
str = str + ""
End If
str = "Provider=Microsoft.Jet.OLEDB.3.51;Persist Security Info=False;Data Source=" & str & " sl.mdb"
conn.open str
rs.cursorlocation=aduseclient
rs.open "數(shù)據(jù)表名",conn,adopenkeyset.adlockpessimistic
用完之后關(guān)閉數(shù)據(jù)庫(kù)：
conn.close
set conn=nothing
(完)
