Dim hwnd11 As Integer

第二個(gè)是你要生成EXE后 運(yùn)行EXE

第三就是沒(méi)好像沒(méi)有文本框控件

vb.net如何找到一個(gè)網(wǎng)頁(yè)中的按鈕的句柄

網(wǎng)頁(yè)中的按鈕沒(méi)有句柄可言，只有控件id，你想要的到底是什么，找到按鈕模擬點(diǎn)擊按鈕？

找到按鈕不難，查找input，id是那個(gè)按鈕的話就用DOM獲取到，然后發(fā)送.click方法

也可以用附加js腳本的方式來(lái)實(shí)現(xiàn)點(diǎn)擊那個(gè)按鈕，js腳本里實(shí)現(xiàn)獲取那個(gè)按鈕并點(diǎn)擊

求vb.net句柄實(shí)例，實(shí)現(xiàn)操作其他程序窗口。如我給的例子
