生成Excel文件与VB6

Question

我要找的建议对这个具体问题：

什么是在Visual Basic 6（VB6）来生成Excel文件（XLS定期，而不是那些XLSX），最快的方法？

非常感谢。

Answer 1

最简单的方法是将项目中的引用设置为Excel COM对象，并以编程方式将所有数据插入到工作表中。

Answer 2

Excel中已经能够读取HTML，因为Excel 2000中

的最简单方法是编写HTML表，并将它们保存扩展名为.xls，或者如果它是一个Web应用程序清除响应缓冲区，设置响应类型为“application/vnd.ms-excel”，并写出表中没有别的。

将以下内容复制并粘贴到记事本中，并以.xls扩展名保存并打开。

<table> 
<tr><th>Color</th><th>Shape</th></tr> 
<tr><td>Blue</td><td>Square</td></tr> 
</table> 

免责声明：

我不推荐这种方法，因为它可能只与Excel兼容的，但它是我所知道的最简单的方法。

Answer 3

在Excel对象库中设置一个引用（在VBA的工具菜单中，项目在VB6中）（不记得确切的名称，但它将以“Microsoft”开头并且在“名称）。

然后是这样的：

Public Sub BuildAndSaveWorkbook 

    With New Excel.Workbook 
     ' do all the stuff to create the content, then' 
     .SaveAs Filename:="WhateverYouWantToCallIt.xls", FileFormat:=xlExcel8 
    End With 

End Sub

创建XLS文件，最快的方式是使用Jet的ISAM驱动程序用于Excel。下面是一个示例如何使用ADO和ADOX做到这一点：

' References: 
' Microsoft ActiveX Data Objects 2.8 Library 
' Microsoft ADO Ext. 2.8 for DDL and Security 
Option Explicit 

Private Sub Command1_Click() 
    Dim rs    As ADODB.Recordset 

    Set rs = CreateRecordset(_ 
     "ID", adDouble, _ 
     "Name", adVarWChar, 200, _ 
     "Value", adDouble, _ 
     "Memo", adLongVarWChar) 
    rs.AddNew Array("ID", "Name", "Value", "Memo"), _ 
     Array(1, "test", 5.1, "long long text here") 
    rs.AddNew Array("ID", "Name", "Value"), _ 
     Array(1, "proba", 15.678) 
    AppendExcelSheet rs, App.Path & "\test.xls", "My Data", True 
    AppendExcelSheet rs, App.Path & "\test.xls", "More Data" 
End Sub 

Private Function CreateRecordset(ParamArray FldDesc()) As ADODB.Recordset 
    Dim lIdx   As Long 

    Set CreateRecordset = New ADODB.Recordset 
    With CreateRecordset.Fields 
     Do While lIdx < UBound(FldDesc) 
      Select Case FldDesc(lIdx + 1) 
      Case adDouble, adDate, adCurrency, adBoolean 
       .Append FldDesc(lIdx), FldDesc(lIdx + 1), , adFldIsNullable 
       lIdx = lIdx + 2 
      Case adVarWChar 
       .Append FldDesc(lIdx), FldDesc(lIdx + 1), FldDesc(lIdx + 2), adFldIsNullable 
       lIdx = lIdx + 3 
      Case adLongVarWChar 
       .Append FldDesc(lIdx), FldDesc(lIdx + 1), -1, adFldIsNullable 
       lIdx = lIdx + 2 
      Case Else 
       Err.Raise vbObjectError, , "Not support Excel data type!" 
      End Select 
     Loop 
    End With 
    CreateRecordset.Open 
End Function 

Private Function AppendExcelSheet(_ 
      rsSrc As Recordset, _ 
      sXlsFile As String, _ 
      Optional ByVal sSheetName As String, _ 
      Optional ByVal bCreateNew As Boolean) As Boolean 
    Dim sConnStr  As String 
    Dim oTbl   As ADOX.Table 
    Dim oCol   As ADOX.Column 
    Dim oFld   As ADODB.Field 
    Dim rsDst   As ADODB.Recordset 

    '--- init local vars 
    sConnStr = "Provider=Microsoft.Jet.OLEDB.4.0;" & _ 
     "Data Source=" & sXlsFile & ";Extended Properties=""Excel 8.0;Read Only=0""" 
    If LenB(sSheetName) = 0 Then 
     sSheetName = "Sheet1" 
    End If 
    '--- cleanup previous file 
    If bCreateNew Then 
     On Error Resume Next 
     SetAttr sXlsFile, vbArchive 
     Kill sXlsFile 
     On Error GoTo 0 
    End If 
    '--- create/open workbook and append worksheet 
    With New ADOX.Catalog 
     .ActiveConnection = sConnStr

     oTbl.Name = sSheetName 
     For Each oFld In rsSrc.Fields 
      Set oCol = New ADOX.Column 
      With oCol 
       .Name = oFld.Name 
       .Type = oFld.Type 
      End With 
      oTbl.Columns.Append oCol 
     Next 
     .Tables.Append oTbl 
    End With 
    '--- copy data to range (named after worksheet) 
    If rsSrc.RecordCount > 0 Then 
     Set rsDst = New ADODB.Recordset 
     rsDst.Open "[" & sSheetName & "]", sConnStr, adOpenDynamic, adLockOptimistic 
     rsSrc.MoveFirst 
     Do While Not rsSrc.EOF 
      rsDst.AddNew 
      For Each oFld In rsSrc.Fields 
       rsDst.Fields(oFld.Name).Value = oFld.Value 
      Next 
      rsDst.Update 
      rsSrc.MoveNext 
     Loop 
    End If 
End Function
