cab安裝時如何更新安裝新版本控件

1.首先要編譯好新版本的控件。

 

2.在頁面調用時在codebase 屬性中加入新版本號

例如：

修改前：

< OBJECT id = " formx " classid = " CLSID:E5022E7E-758C-4A32-99C6-55742289301D " height = " 90% " width = " 100% " codebase = " cab/KoalForm.cab#version=1,0,0,1 " VIEWASTEXT ></ OBJECT >

修改後：

< OBJECT id = " formx " classid = " CLSID:E5022E7E-758C-4A32-99C6-55742289301D " height = " 90% " width = " 100% " codebase = " cab/KoalForm.cab#version=1,0,0,2 " VIEWASTEXT ></ OBJECT >
