說明
本功能就是直接點擊cad圖元獲取vla函數,快速知道圖元對應的方法和屬性(存在可用的).
小賤賤他復刻了一個高版本用的vlisp小助手,因為他調用了高版本函數,導致沒有Acad08版,我很郁悶,然后就在他的基礎上造了一個net全版本通用的...
至於貓老師曾經實現過的,通過幫助文件實現參數獲取,我懶得做了,要新建數據庫做快速索引才行,還要對數據庫整理...
動圖演示
制作過程
亂碼
Acad08測試時候:
以下操作不加T表示僅看vlisp支持的屬性,加T表示加看vlisp支持的方法,而加T時候會有亂碼信息.
(if (setq ent (entsel))(progn (vlax-dump-object (vlax-ename->vla-object(car ent))T)))
它會將";支持的方法:" 會隨機變成 ";?С值姆椒?"...等等含有"椒"字的字符串,由於直接使用Acad08獲取都有,
所以這無法通過改變字符串編碼修改,懷疑是Win10系統中文和Acad08編譯環境不同導致.
處理方法詳情見代碼SplitMethod內,這可能僅發生在Acad08或者net35下,因為我用Acad21測試並沒有這樣的問題.
如果是lisp寫小助手,恐怕每次獲取都是不一樣的碼值(lisp的解釋器有bug),無法用eq/equal對比,因為圖層亂碼是導致我學c#原因之一...
這可能就是不死貓老師vlisp小助手會出現有的能用,有的不能用的問題.
對話框模式和發送命令
代碼同時支持調用winform的模態窗口和非模態窗口兩種方式,可自己修改為自己喜歡的.
首先要說明: 先要發送復制命令歷史命令,再從剪貼板獲取歷史.
1: 當發送命令時,此時要同步處理剪貼板,那么需要同步命令,但是非模態不能發送同步命令,否則出現Acap.DocumentManager.IsApplicationContext == true 命令上下文的報錯.
2: 異步命令會導致先獲取剪貼板,之后才發送了復制命令歷史.而cad異步命令又沒有執行完成后的回調.
在我一籌莫展的時候,edata給了我個建議:
寫一個自己的同步命令,在命令內發送復制命令歷史命令,再在剪貼板獲取命令,並且修改窗體信息.
然后點擊圖元時候發送異步命令,調用這個自寫的同步命令,這樣執行順序就是正常的,窗體也能得到信息.
簡直妙到不行,有一種用魔法打敗魔法的感覺.

Arx制作
由於Arx可以通過重寫命令欄的方式攔截命令文本數據,所以不需要像c#一樣在那繞圈圈,
便可以導出命令歷史到窗體上面,不過實現了功能就好啦🌚
后記
實際上我們需求是反射圖元下面所擁有的東西,那么,我們為什么要靠net調用arx反射?
我們net可是有API的啊!所以只需要反射圖元就好了...
