vb中如何用calendar控件查找数据库内容

Answer 1

Public Function ConnectString() _
As String

ConnectString = "FileDSN=info.dsn;UID=sa;PWD=23" '连接字符器，改成你自己的
End Function
Public Function ExecuteSQL(ByVal SQL _
As String, MsgString As String) _
As ADODB.Recordset '这里是执行SQL语句，你只需要调用这个方法，把SQL查询语句参数传进来，最后返回一个Recordset

Dim cnn As ADODB.Connection
Dim rst As ADODB.Recordset
Dim sTokens() As String
On Error GoTo ExecuteSQL_Error
sTokens = Split(SQL)
Set cnn = New ADODB.Connection
cnn.Open ConnectString
If InStr("INSERT,DELETE,UPDATE", _
UCase$(sTokens(0))) Then
cnn.Execute SQL
MsgString = sTokens(0) & _
" query successful"
Else
Set rst = New ADODB.Recordset
rst.Open Trim$(SQL), cnn, _
adOpenKeyset, _
adLockOptimistic
'rst.MoveLast 'get RecordCount
Set ExecuteSQL = rst
MsgString = "查询到" & rst.RecordCount & _
" 条记录 "
End If
ExecuteSQL_Exit:
Set rst = Nothing
Set cnn = Nothing
Exit Function
ExecuteSQL_Error:
MsgString = "查询错误: " & _
Err.Description
Resume ExecuteSQL_Exit
End Function
Public Function Testtxt(txt As String) As Boolean
If Trim(txt) = "" Then
Testtxt = False
Else
Testtxt = True
End If
End Function
