在C#中使用ocx文件 [英] Using an ocx file with C#

问题描述

我必须在C#Windows应用程序中使用ocx文件.我能够成功引用和访问ocx文件中定义的方法.但是:

Hi,

I have to use an ocx file with my C# Windows application. I am able to successfully refer and and access the methods defined in the ocx file. But:

1. 当我尝试实例化对象时，例如
   

1. When I am trying to instantiate the object like
   

objIRC = new IRCClass();

然后我编译时间错误是 类型" IRC.IRCClass没有定义构造函数"

所以我尝试了新关键字.发生对象引用错误 对象引用未设置为对象的实例" .在谷歌搜索时，我得到了一些建议，建议使用Activator方法，但发现效果并不理想.

then I compile time error is getting "The type ''IRC.IRCClass'' has no constructors defined"

So I tried with out new keyword. The object reference error is occuring ''Object reference not set to an instance of an object''. On googling I got some advice to use the Activator methods, which I found not good.

你知道为什么会这样吗?
注意:我只有ocx文件.不知道.

谢谢你

Do you have any idea why this is happening?
NB: I only have the ocx file. No idea about it.

Thanking you

推荐答案

这仅表示无法实例化此类，但具有私有或受保护的构造函数.看看您在哪里下载了它，也许他们为如何使用它提供了指示.

祝你好运！

This simply means that this class cannot be instantiated but is has private or protected constructors. Have a look at where you downloaded it maybe they give pointers on how to use it.

Good luck!
