VB学生宿舍管理系统(十)

VB学生宿舍管理系统(十) ist中加载各表名。以便进行选择转换。添加表名部分在load进行加载，其中的导出与取消按钮是由coolbar制作而成。
Form的load事件处理内容如下：
TMaxAni1.FileName = App.Path & "\icon\find.gif"
TMaxAni1.ShowGif
Dim cnn1 As ADODB.Connection
Dim rstschema As ADODB.Recordset
Dim strcnn As String
Set cnn1 = New ADODB.Connection
strcnn = "provider=Microsoft.jet.oledb.4.0;" & "data source=" & App.Path & "\db.mdb"
cnn1.Open strcnn
Set rstschema = cnn1.OpenSchema(adSchemaTables)
Do Until rstschema.EOF
temp = rstschema!Table_Name
If Left(temp, 1) <> "M" Then
List2.AddItem temp
End If
rstschema.MoveNext
Loop
cnn1.Close
List2.ListIndex = 0
On Error GoTo err
PathName = App.Path & "\db.MDB"
dbasize = FileLen(PathName)
数据转换成excel用到了一个部件，在引用中用到了Microsoft Excel9.0 Object library。转换代码如下：
Select Case Button.Index
Case 1
 Dim provider As String
Dim datasource As String
provider = "provider=Microsoft.jet.oledb.4.0"
datasource = "data source=" & App.Path & "\DB.mdb"
With Adodc1
.Mode = adModeReadWrite
.ConnectionString = provider & ";" & datasource
.CommandType = adCmdTable
.RecordSource = List2.Text
.Refresh
End With
ProgressBar1.Max = Adodc1.Recordset.RecordCount
ProgressBar1.Min = 0
'开始转换
Dim Irow, Icol As Integer
  Dim Irowcount, Icolcount As Integer
  Dim Fieldlen()
  Dim xlApp As Excel.Application
