如何使用ocx？程序自动生成了一个pas，然后怎么办？显示pdf文件内容的问题。(50)

我想在程序中显示pdf内容，但是不知道如何使用？我搜索了论坛看到说使用import activex，我也已经加入了pdf的activex，程序给我自动生成了一个pas，但是在往后怎么用……我实在是不知道了，能否帮我详细说下？非常感谢！！

有人帮忙看看么？我看着他给的那个pas就是interface，我就想知道如何去写定义和调用……

导入完成会成成一个tlb文件,当你引用这个控件的时候会在use段看到这个文件,查看这个文件内容就可以找到可以调用的过程的定义及参数

我也是这么用的可是我用pda.loadfile('d:/1.pdf').总是报错。应该如何调用？这是我导入的那个pas文件，谁能帮我看看应该如何使用？我可以单开帖子在给分～非常感谢！！unit AcroPDFLib_TLB;
