CAD从二进流加载数据（com接口VB语言）

主要用到函数说明：

MxDrawXCustomFunction::ReadBinStreamEx

从二进流加载数据，详细说明如下：

参数	说明
IMxDrawBinStream* pBinStream	二进制流对象

代码实现如下：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

Dim param As MxDrawResbuf Set param = New MxDrawResbuf   Dim ret As MxDrawBinStream   Set ret = MxDrawX1.CallEx("WriteBinStreamEx", param)   If ret.GetCount() > 0 Then       MsgBox "保存成功执行"   End If   ' 读取 Dim retRead As MxDrawResbuf Set retRead = MxDrawX1.CallEx("ReadBinStreamEx", ret) If retRead.AtString(0) = "Ok" Then     MsgBox "读取成功执行" End If
