在前面用C#開(kāi)發(fā)完CRM的來(lái)電彈屏之后，有些客戶有了新的要求，他們希望不但能夠?qū)崿F(xiàn)來(lái)電彈屏，更希望能夠?qū)⒑羧牒舫龅碾娫掍浺舨⑸蟼鞯紺RM服務(wù)器上，方便日后跟蹤記錄。于是便有了來(lái)電小秘書(shū)客戶端的開(kāi)發(fā)。 來(lái)電小秘書(shū)客戶端的開(kāi)發(fā)是基于紐曼USB來(lái)電通客戶端的基礎(chǔ)上進(jìn)行開(kāi)發(fā)的，由于紐曼USB來(lái)電通的硬件沒(méi)有錄音功能，于是硬件上使用了紐曼的另一個(gè)硬件產(chǎn)品來(lái)電小秘書(shū)，雖然是同一個(gè)廠家的產(chǎn)品，可是它們的API卻是完全不兼容，更煩的是，來(lái)電小秘書(shū)API沒(méi)有來(lái)電的回調(diào)接口，無(wú)法通過(guò)回調(diào)觸發(fā)程序，也沒(méi)有C#的Demo，很多功能只能通過(guò)一個(gè)不是那么詳細(xì)的文檔和一個(gè)Delphi的Demo摸索著做了，經(jīng)歷了一些挫折和困惑，終于完成了這個(gè)客戶端程序。 首先，開(kāi)發(fā)要做的就是與硬件的API進(jìn)行溝通，依然通過(guò)C#的P/Invoke來(lái)完成，以下是來(lái)電小秘書(shū)的P/Invoke代碼。
