以下程序直接执行不可以，但如果在vbarun对话框选逐语句就可以运行．
开始时我想在对话框按下一个按纽，然后在图上选一个点，插入一个块，就用了sample的程序试了一下，结果对话框是焦点的情况下不能用utility的getpoint,只能在form1.hide之后才能utility.getpoint．后来发现，ThisDrawing.SendCommand 以后对话框还在，但不是焦点,可以用utility.getpoint,所以我想在getpoint前用一个空的指令，让对话框仍然显示在屏幕上，但不是焦点．
Private Sub CommandButton2_Click()
Dim returnPnt As Variant
ThisDrawing.SendCommand ("_open")
returnPnt = ThisDrawing.Utility.GetPoint(, "Enter a point: ")
MsgBox "The WCS of the point is: " & returnPnt(0) & ", " & returnPnt(1) & ", " & returnPnt(2) & vbCrLf & _
"(Enter the next value without prompting.)", , "GetPoint Example"
returnPnt = ThisDrawing.Utility.GetPoint
MsgBox "The WCS of the point is: " & returnPnt(0) & ", " & returnPnt(1) & ", " & returnPnt(2), , "GetPoint Example"
Dim basePnt(0 To 2) As Double
basePnt(0) = 2#: basePnt(1) = 2#: basePnt(2) = 0#
returnPnt = ThisDrawing.Utility.GetPoint(basePnt, "Enter a point: ")
MsgBox "The WCS of the point is: " & returnPnt(0) & ", " & returnPnt(1) & ", " & returnPnt(2)
Dim lineObj As AcadLine
Set lineObj = ThisDrawing.ModelSpace.AddLine(basePnt, returnPnt)
ZoomAll
UserForm1.Show
