This post originally appeared on Joycode on Sept 17 2004. 在文件选择对话框和浏览器中都可以显示文件夹视图，但是有时需要对显示的方式进行控制，例如在文件选择对话框初始化时设置显示方式为详细资料视图或者缩略图视图，有的时候需要用程序来选择一些项目，例如在文件选择对话框中添加全选按钮，或者打开文件所在文件夹并且选中指定文件。 我在大约一年之前的一个Post(http://blog.joycode.com/jiangsheng/archive/2003/11/09/6152.aspx)中提及到这个问题，搞定了之后一直忘记公布答案了，今天在CSDN社区看到别人问的类似问题才想起自己已经解决了，所以现在拿出来分享…… 关于如何设置文件夹视图的显示方式的问题，Paul DiLascia在他的MSDN杂志C++Q&A专栏中提供了另一个解决方案。参见List View Mode, SetForegroundWindow, and Class Protection(http://msdn.microsoft.com/msdnmag/issues/04/03/CQA/)。PS:这家伙又用Spy++大法…… 浏览器控件显示文件夹视图（例如本地目录或者FTP站点）时在其中双击目录，选中的目录会用新的资源管理器窗口打开的问题，是因为浏览器控件中的文件夹视图在打开文件夹的时候并不触发浏览器的NewWindow2事件，而是调用ShellExecuteEx，用DDE的方式和Shell通讯。微软知识库文章Q189634 WebApp.exe Enables User to Move WebBrowser Ctrl（http://support.microsoft.com?kbid=189634）描述了如何处理这样的DDE会话。呃……顺便说一下，这篇文章文不对题…… 下面的给出访问文件打开/保存对话框和浏览器控件的文件夹视图的代码(MFC) #ifndef WM_GETISHELLBROWSER#define WM_GETISHELLBROWSER (WM_USER+7)//差不多一年过去了，这个消息还是a yet-to-be documented message#endif void CCustomFileDialog::OnInitDone(){CFileDialog::OnInitDone();//Remember, when you … Continue reading →

OopFactory.X12 can parse EDI messages into segments and loops. However despite typed segments and loops exist, the parser does not generate them in the object model.  The unit test only use them when generating EDI messages. The typed segments and … Continue reading →

Got called into a memory leak troubleshooting. The application was leaking memory at 1mb per second. In memory profiler, most of the growing memory are used by byte[] and RuntimeMethodHandle (growing at around a million per minute). Initially I thought … Continue reading →

微软拼音最近每次激活的时候都要卡上个几分钟。而且不是一个程序只卡一次，中英文切换之后还会继续卡。 用了Process Monitor跟踪了一下，发现每次切换中英文的时候，微软拼音都会在%appdata%\Microsoft\InputMethod\Chs下面创建一个名字为UDPXXXX（这里XXXX是16进制数字）.tmp的文件，我这个目录下有六万五千多个这样的文件。从命名风格来看，很明显是在调用GetTempFileName，而这个函数有65535个文件的限制，不删除文件的话，第65536次调用会失败，应该是微软拼音没有处理好调用这个函数失败的情况，也没有删除临时文件的代码，就卡住了。 目前的绕过这个问题的方法是把 del %appdata%\Microsoft\InputMethod\Chs\*.tmp /q 加到每日备份脚本。 已经向微软反映了这个问题。不知道微软为什么临时文件不放%TEMP%放应用程序目录下，以及为什么不定期清理自己创建的临时文件。
