4、oreDirectory.- SafeFileName SafeFileNamesShowDialogShowHelp ShowReadOnly Site SupportMultiDottedExtensions ft lotina 腳本之家 jJ ValidateNames提到擴(kuò)展，很多人可能想到繼承它就可以擴(kuò)展它，可惜OpenFileDialog聲明為sealed，不允許從他繼承。稍 微底層一點(diǎn)的，想到可以通過Win32 API來修改它的顯示方式，只可惜，如你所見，它根本沒提供Handle 屬性，更別說 HandleCreated、HandleDestroyed 等事件了。那么怎么樣子搞呢

5、？其實(shí)答案還是通過 Win32 API,只是我們?nèi)〉盟木浔姆绞揭獜?fù)雜一點(diǎn)而且調(diào)用API的時(shí)機(jī)隱晦了一點(diǎn)。提示：1.Win32 API 操作窗體需要知道窗體的句柄；2不熟悉Win32編程的同學(xué)可以先上網(wǎng)查查資料，特別是不知道SetParent、SetWindowPos等API是干嘛的，我覺得以下的看 不懂。為什么說取得它的句柄復(fù)雜了一點(diǎn)？難道不是用“FindWindow”、“FindWindowEx”、“ EnumChildWindows” 等獲取 OpenFileDialog 的句柄，再用“SetParent、“SetWindowPos等 API 將.net 控件（本例中是 DataGri

6、 dView控件，當(dāng)然可以使其他任何一種）添加到OpenFileDialog中去？沒錯，以上列舉出來的API都是基本 要用到的，“只是用在什么地方、什么時(shí)候用是個(gè)比較麻煩的問題，原因如下：1）我們知道OpenfileDialog顯示的是模式對話框，也就是說，一旦它ShowDialog （），它以下的代碼是不會 再執(zhí)行的，具體原因是什么（我以后的博客會專門講為什么），你現(xiàn)在可以理解為OpenFileDialog（）方法會阻 塞調(diào)用線程，既然阻塞了調(diào)用線程，那么我們再無法控制程序了（直到它返回），根本談不上再調(diào)用API獲 取OpenFileDialog的句柄然后去操作它。如果有人會說，我可以另開辟

7、線程去取OpenFileDialog得句柄再 操作它”，恩，我不否定這個(gè)方法，只是我想說，如果你真的按照這個(gè)方法去試，那么肯定會陷入泥潭。因 為你不僅要取它的句柄，你還要監(jiān)視 OpenFIleDialog 的一舉一動，移動、縮放、用戶鼠標(biāo)點(diǎn)擊選擇文件、 更改目錄等，然后再操作.net控件（本例中是DataGridView控件，下同），讓.net控件去適應(yīng)OpenFileDial og的大小等等，你會發(fā)現(xiàn)你忙死了，甚至有的你根本監(jiān)視不了，比如用戶點(diǎn)擊選擇文件、更改目錄。2）就算我們能夠在OpenFIleDialog顯示之后，取得它的句柄，那么什么時(shí)候再調(diào)用其他API呢？比如什么 時(shí)候調(diào)用SetW

8、indowPos，讓.net控件適應(yīng)OpenFileDialog的大小變化？什么時(shí)候知道用戶選擇文件發(fā)生了 變化？所以，API方法什么時(shí)候用？用在什么地方？就是接下來要討論的東西。我不知道各位在使用各種框架的時(shí)候，對“框架”的理解到什么程度，我覺得可以總結(jié)成一句話“跟個(gè)2b 似地注冊一些事件，然后苦逼地去寫好每一個(gè)回調(diào)方法，我們卻不知道為啥要這樣寫”，不是么？既然這樣， 那么我們的API方法只要寫在了正確的回調(diào)方法中，我們就能到達(dá)想要的目的了?？紤]幾個(gè)問題：1）OpenFileDialog顯示，我們向其中添加.net控件。我們什么時(shí)候知道它顯示？2）OpenFileDialog大小發(fā)生變化時(shí)，

9、我們要更新.net控件以適應(yīng)新的大小。我們什么時(shí)候知道OpenFileDial og的大小發(fā)生了變化？3）OpenFileDialog中用戶選擇的文件發(fā)生了變化，我們需要知道新選擇的文件路徑，用來顯示在.net控件 中。我們怎么知道選擇了什么文件？（這里選擇文件指用戶用鼠標(biāo)在OpenFileDialog中單擊選取不是點(diǎn)擊 “確定”后。）以上所有的問題，其實(shí)在一個(gè)地方都可以知道，那就是監(jiān)聽OpenFileDialog窗體的Windows消息，因?yàn)橐?個(gè)窗體的任何一個(gè)動作都伴隨著一系列的Windows消息（這個(gè)可以用Spy+查看）。既然這樣，那么我們可 以在窗體處理Windows消息的回調(diào)方法中調(diào)

10、用API方法了，也就是窗體的Control.WndProc方法中。之前已 經(jīng)說過了，OpenFileDialog聲明為Sealed，提供的接口少之又少，我們幾乎根本不可能接觸到OpenFileDial og的WndProc，更談不上監(jiān)聽Windows消息，然后調(diào)用API去操作它。這時(shí)候，NativeWindow該出場了， 先來引用一下MSDN上對NativeWindow的解釋：“提供窗口句柄和窗口過程的低級封裝?！闭f了像沒說一樣，其實(shí)就是說，將一個(gè)窗口句柄與NativeWindow對象綁定后，該NativeWindow對象就能 接收到這個(gè)窗體的所有消息。說到 Windows 消息，我想說一下

11、Windows 桌面應(yīng)用程序的運(yùn)行流程，其實(shí) 如果看了我前一篇博客的同學(xué)應(yīng)該有些了解，中基本提到了一些。為了配合本次講解，我再次畫了一張圖上圖中，虛線框可以看做是一個(gè).net中的Control類對象（或者其派生類，下同，控件即窗體、窗體即控件）, 正常情況下，Winform程序會按照1-2-3的步驟運(yùn)行，當(dāng)我們將Control類對象的Handle （就是我們常說 的窗口句柄，做了一下封裝）與一個(gè)Nativewindow對象綁定后，程序不再按照1-2-3這樣的順序運(yùn)行了， 他會按照1-2-1-2-2-3這樣運(yùn)行，也就是說，Nativewindow對象可以攔截Control類對象的Windows消

12、 息，我們完全可以在Nativewindow中重寫他的WndProc方法，像處理自己的Windows消息一樣去處理C ontrol類對象的消息。所以，我們就可以在Nativewindow對象的WndProc中調(diào)用我們的API方法。接下來，上代碼（代碼只提供大概思路）1.擴(kuò)展對話框復(fù)制代碼弋碼如下：i#region fieldsprivate const SetWindowPosFlags UFLAGSHIDE =SetWindowPosFlags.SWP_NOACTIVATE |SetWindowPosFlags.SWP_NOOWNERZORDER |SetWindowPosFlags.SWP
