[求助]请教高手：在AutoCAD VBA中怎么打开Excel文件？？
我用通用对话框打开Excel文件，但是不知为何总出错，高手请指教！Dim Excel As Excel.Application
Dim ExcelSheet As Object
Dim ExcelWorkbook As Object
Dim ExcelName As String
'设置标准对话框
With comDlg
.DialogTitle = "选择Excel文件"
.Filter = "Excel文件(*.xls)|*.xls|所有文件(*.*)|*.*"
.InitDir = "d:\my documents"
.ShowOpen
End With
'文件类型错误的判断
If Right(comDlg.FileName, 3)"xls" Then
MsgBox "不支持的文件格式！", vbCritical, "警告"
Exit Sub
End If
'打开文件的操作
'Open comDlg.FileName For Input As #1
'Close #1
ExcelName = comDlg.FileName
Excel.Workbooks.Open ExcelName
这样总有错误，说什么
Object variable or With block variable not set (Error 91)我看了半天也没懂什么原因。
但是用以下代码就正确。
'*********************************************************************************
'错误处理
'On Error Resume Next
'Set Excel = GetObject(, "Excel.Application")
'If Err0 Then
'Set Excel = CreateObject("Excel.Application")
'End If
'打开excel表
'ExcelName = InputBox("路径：")
'Excel.Workbooks.Open ExcelName
'********************************************************************************
这样就是用了inputbox。但就是每次要打开excel文件就要手动输入文件名。太麻烦了。。。
请高手们指教！
这两条语句是关键语句
Set Excel = GetObject(, "Excel.Application")
Set Excel = CreateObject("Excel.Application")
excel文件就要手动输入文件名。太麻烦了
你要达到什么目的?
我要选择一个excel文件的数据，在autocad中根据数据画出图形来。
看看我发的帖子，有专题描述，AutoCad二次开发教程有详细的介绍。
你最好发个示例，好给你讲解。
这是具体的代码
是个画纵断面的程序，还有一个测试用的excel文件
按照兰州人大哥的话
Set Excel = GetObject(, "Excel.Application")
Set Excel = CreateObject("Excel.Application")
这两句话我加上去了，貌似果然正常了。。。
我也有类似疑问，不知道如何编程实现将EXCEL中的数据（坐标值，标高等）导入CAD中自动生成平面或者空间的单线图（轴线图，钢框架结构） 我发个例子给你：
Sub clb() '画材料表
On Error GoTo err
Dim textObj As AcadText
Dim myselect(0 To 13) As AcadEntity
Dim mytxt As AcadTextStyle '定义mytxt变量为文本样式
Dim d As Long
Dim p(0 To 2) As Double '插入点
Dim excelapp As Excel.Application '定义excle应用程序变量
Dim excelsheet As Worksheet '定义工作表变量
Dim p1 As Variant '申明端点坐标
Dim p2 As Variant '申明端点坐标
Dim i As Long
Dim x As Long
Dim y As Long
Dim a1(0 To 2) As Double
Dim a2(0 To 2) As Double
Dim pp(0 To 9) As Double '定义点坐标
Dim txt

Dim attrtxt0 As String
