[求助]关于sendcommand的疑问

mikewolf2k 发表于 2005-10-13 22:41:00

在vba中用sendcommand，好像与vba执行并不是同步的，比如下面这段代码，多次执行的结果并不是相同的，请问有什么办法能确保sendcommand的语句在acad中执行完毕后再执行sendcommand下一句vb代码？
Sub bb()       lsp = "(command ""text"" ""mc"" """ & 0 & "," & 0 & """ ""2"" ""0"" """ & "0" & """)"       ActiveDocument.SendCommand lsp & vbCr       lsp = "(command ""text"" ""mc"" """ & 1 & "," & 1 & """ ""2"" ""0"" """ & "1" & """)"       ActiveDocument.SendCommand lsp & vbCr       lsp = "(command ""text"" ""mc"" """ & 2 & "," & 2 & """ ""2"" ""0"" """ & "2" & """)"       ActiveDocument.SendCommand lsp & vbCr       lsp = "(command ""text"" ""mc"" """ & 3 & "," & 3 & """ ""2"" ""0"" """ & "3" & """)"       ActiveDocument.SendCommand lsp & vbCr       lsp = "(command ""text"" ""mc"" """ & 4 & "," & 4 & """ ""2"" ""0"" """ & "4" & """)"       ActiveDocument.SendCommand lsp & vbCr       lsp = "(command ""text"" ""mc"" """ & 5 & "," & 5 & """ ""2"" ""0"" """ & "5" & """)"       ActiveDocument.SendCommand lsp & vbCr       lsp = "(command ""text"" ""mc"" """ & 6 & "," & 6 & """ ""2"" ""0"" """ & "6" & """)"       ActiveDocument.SendCommand lsp & vbCr       lsp = "(command ""text"" ""mc"" """ & 7 & "," & 7 & """ ""2"" ""0"" """ & "7" & """)"       ActiveDocument.SendCommand lsp & vbCr       lsp = "(command ""text"" ""mc"" """ & 8 & "," & 8 & """ ""2"" ""0"" """ & "8" & """)"       ActiveDocument.SendCommand lsp & vbCr       lsp = "(command ""text"" ""mc"" """ & 9 & "," & 9 & """ ""2"" ""0"" """ & "9" & """)"       ActiveDocument.SendCommand lsp & vbCr       lsp = "(command ""text"" ""mc"" """ & 10 & "," & 10 & """ ""2"" ""0"" """ & "10" & """)"       ActiveDocument.SendCommand lsp & vbCr
End Sub

就为了生成几个简单的文字，不用那么复杂吧。读你的程序的人会有麻烦的。

 我只是举例说明连续写text时会出现问题，当然不是实际上这么用。

一定要可以这样
    lsp = "(progn (setvar ""cmdecho"" 0) "     lsp = lsp & "(command ""text"" ""mc"" """ & 0 & "," & 0 & """ ""2"" ""0"" """ & "0" & """)"     lsp = lsp & "(command ""text"" ""mc"" """ & 1 & "," & 1 & """ ""2"" ""0"" """ & "1" & """)"     lsp = lsp & "(command ""text"" ""mc"" """ & 2 & "," & 2 & """ ""2"" ""0"" """ & "2" & """)"     lsp = lsp & "(command ""text"" ""mc"" """ & 3 & "," & 3 & """ ""2"" ""0"" """ & "3" & """)"     lsp = lsp & "(command ""text"" ""mc"" """ & 4 & "," & 4 & """ ""2"" ""0"" """ & "4" & """)"     lsp = lsp & "(command ""text"" ""mc"" """ & 5 & "," & 5 & """ ""2"" ""0"" """ & "5" & """)"     lsp = lsp & "(command ""text"" ""mc"" """ & 6 & "," & 6 & """ ""2"" ""0"" """ & "6" & """)"     lsp = lsp & "(command ""text"" ""mc"" """ & 7 & "," & 7 & """ ""2"" ""0"" """ & "7" & """)"     lsp = lsp & "(command ""text"" ""mc"" """ & 8 & "," & 8 & """ ""2"" ""0"" """ & "8" & """)"     lsp = lsp & "(command ""text"" ""mc"" """ & 9 & "," & 9 & """ ""2"" ""0"" """ & "9" & """)"     lsp = lsp & "(command ""text"" ""mc"" """ & 10 & "," & 10 & """ ""2"" ""0"" """ & "10" & """)"     lsp = lsp & "(setvar ""cmdecho"" 1))"     Dim fso As New FileSystemObject     Dim ts As TextStream     Set ts = fso.CreateTextFile("d:\mycmd.lsp")     ts.Write lsp     ts.Close     ThisDrawing.SendCommand "(load ""d:\mycmd.lsp"")" & vbCr     Kill "d:\mycmd.lsp"

这个问题我很就遇到了，我是求各一个任意线条的均分点，因为CAD中没有这样的函数，所以只有用SendCommand，但是经常出错，如果单步执行，则从不出错。

请版主指定5楼代码要加载什么库。
另外我的程序是写一个文本，然后用vb对该文本进行一些设置，比如字高、字宽等。必须等lisp执行完后再执行下一句vb代码，这样可以吗？

Microsoft Scripting Runtime

mikewolf2k 发表于 2005-10-17 22:11:00

还是有问题，一步步执行可以，连续执行不行。而且一步步执行的结果也不对，同样各次运行的结果也不一定相同。
