I just missed my connecting flight in Chicago, so have 3 hours to pass until the next, and decided to post some code I finally got around to writing on the plane from Zurich.Ive had a few requests

As mentioned in this previous post, tomorrow were delivering a fun (and free!) AutoCAD development-oriented webcast entitled "AutoCAD: 10 easy ways to crash your AutoCAD addin". In case its not obvi

A comment came in on this previous post regarding how best to know whether a media name is valid during your plot configuration.There are a few approaches, other than the one I chose of hardcoding t

Just a quick post today regarding an AU Unplugged! topic Ive submitted.The proposed session is called "Developing applications for AutoCAD: best practices for using AutoCADs APIs." Heres the de

This was a fun one to work on. The code in this post combines and extends upon techniques shown in two earlier posts: one showing how to plot multiple sheets and the other showing how to preview a s

 This question was asked as comment to a previous post by har!s:Thanks a lot for the code. I have yet to see 2008 and MultiLeader. But I presume that it works on both Model and paper spaces. In

I thought Id bring your attention to this post on Scott Guthries blog - this is a really exciting announcement for .NET developers everywhere:Releasing the Source Code for the .NET Framework Libra

This post extends this previous post that dealt with driving a single-sheet AutoCAD plot by adding some code to handle selection and transformation of a window to plot.First order of business was to

Im now back from a fantastic break in Italy and am trying hard to catch back up. Next week Im off again to San Diego (work, this time), which may cause further interruptions in blog postings.Thi

 This weeks posts take the code I threw together last week for single-sheet and multi-sheet plotting, and introduces the concept of "plot preview".Im learning as I go for much of this, so there ar

Somewhat symmetrically I’m posting this from Chicago airport, once again, but thankfully I’m now on my way home. It was a busy week of meetings, but I did get the chance to put together some code that

　　获取当前程序文件的路径也算是一个比较常见的需求，比如我有一个文件conn.xml位于.exe的同一目录，在运行时需要从中读取一些设置信息。 　　 　　进程对象在.NET中表现为System.Diagnostics.Process类，通过调用Process.GetCurrentProcess().MainModule.FileName可获得当前执行的exe的文件名。但是这个方法得到的仅仅是文件名

到了.NET后，VS.NET就很难生成一个像VB或者VC里那样的COM了 ，一直没有找到好的解决方法，最近在网上看到了一篇文章说可以用.NET2.0创建可以供VB调用的COM，拿来放着，有空研究一下。　　1.定义接口 　　Com是通过抛出接口让外部应用调用的，每个接口、组件都有一个Guid，

NET API的初始化与清除    在ObjectARX中，"acrxEntryPoint"函数是ARX程序的载入点，程序的初始化和清除均可在该函数中进行。而在.NET API中则首先需要将初始化代码封装在一个类中，同时该类需要压迫实现    IExtensionApplication接口。该接口包含Initialize与Terminate两个函数。其中Initialize负责加载程序时的初始化操

 最近一个项目需要将大文件写入和读取到数据库，觉得可能很多人也需要相关得东西，所以就将代码帖出来protected int state = 0; //表示进度条当前处理的事件类型，1表读取word,2表写入word，3表doc转pdf，4表txt转pdfprivate System.Windows.Forms.Form getDialog(string strFormName,Syst

This topic was briefly introduced almost a year ago, in this post. I then looked into the code a little further in a follow-up post. But at the time this topic wasnt the main thrust of the post, i
