OA辦公系統(tǒng)源碼使用方法

當(dāng)前來說，大部分的OA系統(tǒng)都是通過java的形式來實(shí)現(xiàn)的，可以將OA系統(tǒng)源碼導(dǎo)入到eclipse中查看即可。

步驟一：打開eclipse，選擇菜單欄的file下拉選的import進(jìn)入項(xiàng)目引入設(shè)置界面。

步驟二：選擇要導(dǎo)入的項(xiàng)目路徑后，勾選上projects中的項(xiàng)目名稱。

步驟三：點(diǎn)擊頁面右下角的“Finish”即可完成項(xiàng)目引入。

第四步：在引入的項(xiàng)目上右擊，選擇run on ?server運(yùn)行即可。

視頻會(huì)議軟件開發(fā)源碼（視頻會(huì)議源代碼）

用c#做一個(gè)簡單的視頻會(huì)議系統(tǒng)，要求實(shí)現(xiàn)文件傳輸，會(huì)議主持人和參加會(huì)議的人都實(shí)現(xiàn)相對(duì)的功能！

Anychat有提供C#語音的視頻會(huì)議系統(tǒng)源代碼哦，而且能夠符合你的要求的~需要的話可以跟我聯(lián)系~??！

webrtc源碼用什么語言編寫

必須要安裝的軟件如下： SVN，這個(gè)是必須的?？梢园惭bTortoiseSVN，找個(gè)合適的版本就可以了?！军c(diǎn)擊免費(fèi)試用，0成本啟動(dòng)】

WebRTC實(shí)現(xiàn)了基于網(wǎng)頁的視頻會(huì)議，標(biāo)準(zhǔn)是WHATWG 協(xié)議，目的是通過瀏覽器提供簡單的javascript就可以達(dá)到實(shí)時(shí)通訊（Real-Time Communications (RTC)）能力。

WebRTC（Web Real-Time Communication）項(xiàng)目的最終目的主要是讓W(xué)eb開發(fā)者能夠基于瀏覽器（Chrome\FireFox\...）輕易快捷開發(fā)出豐富的實(shí)時(shí)多媒體應(yīng)用，而無需下載安裝任何插件，Web開發(fā)者也無需關(guān)注多媒體的數(shù)字信號(hào)處理過程，只需編寫簡單的Javascript程序即可實(shí)現(xiàn)，W3C等組織正在制定Javascript 標(biāo)準(zhǔn)API，目前是WebRTC 1.0版本，Draft狀態(tài)；另外WebRTC還希望能夠建立一個(gè)多互聯(lián)網(wǎng)瀏覽器間健壯的實(shí)時(shí)通信的平臺(tái)，形成開發(fā)者與瀏覽器廠商良好的生態(tài)環(huán)境。
