VB.NET應用程序中的JavaScript
[英]JavaScript in VB.NET Application
問題描述
我目前正在開發一個VB.NET應用程序，以優化工作流程並使之自動化。
部分工作是從我們的Intranet下載.pdf文件。 為此，我們使用腳本和CPAU.exe（下面的腳本）打開IE。
然后，我們用“ ITEM”號填寫表格並下載pdf。
Intranet站點然后運行JavaScript以獲取文件。
當前，我通過使用CPAU腳本打開一個新的IE任務，用Document.GetElementByName填寫表單，單擊下載鏈接並使用FindWindowEx打開文件來完成此任務。 但是這種方式不是很可靠，並且可能使用戶感到困惑，因為IE窗口可見1-2秒。 然后下載看不見的文件等。
現在，對於我的應用程序，我想實現JavaScript並直接下載/打開.pdf文件。
這可能嗎，或者還有另一種方法可以做到這一點？
也許使用WebBrowser.InvokeScript Method ？
信息：
填寫“ ITEM”編號的元素名稱：
ctl00$ContentPlaceHolderTitle$tbNumber
用於搜索文件的按鈕：
ctl00$ContentPlaceHolderTitle$btnFind
如果找到文件，則下載鏈接（ID）：
ctl00_ContentPlaceHolderMain_tabQueries_TabPanel1_repeaterSearchResults_ctl01_lbRevision1

這將需要使用其他兩個答案中的信息。
要替換瀏覽器交互，您可以以編程方式創建POST請求，如如何發出HTTP POST Web請求中所示 。
由於您還需要通過請求進行NTLM身份驗證，因此需要將“發出Web請求 ”信息添加到需要Windows身份驗證的網頁中 。
