怎样用vb开发即时命令
各位高手，请教vba或者.net能开发出向CAD内部命令一样使用的命令么？想学习一下cad二次开发，还没有想好学哪个，请大侠不吝赐教，谢谢。 vba是不能直接实现的，必须借助Lisp.NetApi没问题
如果有VB的基础，不如直接学VB.Net或C#
谢谢飞狐兄，前段时间比较忙，一直没有来，我对vb还是比较熟悉，vba经常用，现在正准备抽取时间学习。net
呵呵，我还提问说能不能利用VBA编写内部命令呢，看来不行啊，但是我想能否用VBA调用LISP的语句写一个命令，达到lisp的效果呢，请赐教 选择用
Sends a command string from a VB or VBA application to the document for processing
Use a space or the ASCII carriage return character (vbCr) at the end of the command string to end the command; this is equivalent to pressing ENTER on the keyboard.
This method processes any AutoCAD command-line function, including LISP expressions.
If the drawing specified is not active, it will be made active.
This method is generally synchronous. However, if the command sent with this method requires any user interaction (such as picking a point on the screen) then this method will continue as soon as the user input begins. The command will then continue to be processed asynchronously.
When this method is called from an event handler it is processed asynchronously.
You should never use this method to issue a command for which there is an ActiveX method available. For example, do not use SendCommand "VBALOAD ". Instead, use the LoadDVB method.
