本次是用WPF實(shí)現(xiàn)的是一款基于BT協(xié)議的P2P 播放器。內(nèi)核是用vlc來(lái)實(shí)現(xiàn)。結(jié)果辛辛苦苦做了半天結(jié)果發(fā)現(xiàn)用wpf不能滿足公司一些需求。

所以擱淺，專(zhuān)用winform去開(kāi)發(fā)，主要2個(gè)原因：

1、界面美觀時(shí)發(fā)現(xiàn)渲染視頻的時(shí)候會(huì)有問(wèn)題，這個(gè)問(wèn)題等會(huì)會(huì)講。

2、主要原因如果wpf這個(gè)程序開(kāi)發(fā)完成是不能內(nèi)嵌到網(wǎng)頁(yè)的。因?yàn)楹罄m(xù)還要要開(kāi)發(fā)IE ActiveX 插件。然后總監(jiān)就說(shuō)：那就不用wpf了，轉(zhuǎn)用winform。 我只能呵呵！呵呵呵呵！

wpf我一竅不通，之前完全沒(méi)接觸過(guò)。做出這個(gè)效果已是我最大能力了。（專(zhuān)業(yè)人員請(qǐng)用看小白的態(tài)度）

ok，這里說(shuō)下第一個(gè)問(wèn)題，在渲染視頻的時(shí)候會(huì)發(fā)現(xiàn)只有聲音，沒(méi)有畫(huà)面，在我找了2天問(wèn)題之后發(fā)現(xiàn)是因?yàn)榻缑嬗昧薃llowsTransparency="True" WindowStyle="None" 這段屬性的修改。如果修改一下AllowsTransparency="False" WindowStyle="XXX"(除了不是None之外的都可以)。則就變成這樣了。

 仔細(xì)看，會(huì)多了個(gè)邊框。只有這樣，畫(huà)面才能出來(lái)。 這里可能只有自己重繪這個(gè)界面元素。希望有人能指教一下。

這里我會(huì)將這個(gè)界面的項(xiàng)目打包上傳，點(diǎn)擊這里下載。（有點(diǎn)大，含有vlc的dll文件）因?yàn)槿サ袅薟indowStyle，鼠標(biāo)在邊框進(jìn)行縮放效果和最大化處理以及多顯示器上的兼容都要自己來(lái)實(shí)現(xiàn)。項(xiàng)目都會(huì)有，我其他文章也有對(duì)這些技術(shù)點(diǎn)進(jìn)行部分的講解，這個(gè)就自己去看啦。連接就不打了。

這個(gè)是要利用到WPFToolkit.dll的引用才可以。像這些界面控件的美化一般是用Blend工具來(lái)做的。我都是代碼Copy一些，然后修改一些。 ^.^ 親，代碼要會(huì)抄哦。當(dāng)然了，前提你得懂。這樣也是一種學(xué)習(xí)
