使用HTML界面的Delphi开发环境建立

淩亂°似流年 2021-11-30 01:28 264阅读 0赞

1 SHDocVw\_TLB是shdocvw.dll的类型库导入单元，没有的话就改成shdocvw（delphi自带），或者在“Project”菜单下选“Import Type Library”，在弹出的对话框中再选择“Microsoft Internet Controls”，再点“Create Unit”即可。但是把第二个webbrowser改为webbrowser2.但以后其他工程要用就要改回来了.

2 安装EmbeddedWB\_D2005\_Update12.zip,它包含了IEConst,IEUtil等.

3 安装zoc,在demo中.

4 安装的路径,就是有dcu的路径加入delphi的环境变量 .

附Zoc代码:
