在Form中调用public sub [英] calling public sub in Form
问题描述
为什么我不能在模块或类中调用我的
应用程序主窗体中定义的公共函数或子函数，所有都是
同一个程序集的一部分？
当我在一个类中定义公共函数时，我可以从表单中调用它，
但是如果我在表单中定义公共函数并尝试从
类调用它，它就不起作用。不知道我做错了什么？
谢谢，
Strah

你可以，但你需要有一个类的实例打电话给它，除非
这是一个共享的方法。
// SomeModule
Dim F as New Foo
F.SomeSub< - 这样可以正常工作
// SomeBadModule
F.SomeSub< - 仅在共享时有效
Class Foo
Public Sub SomeSub（）
End Sub
End上课
希望这可以解决它。

你好Chris，
您的输入有帮助。我正在创建
Windows.System.Forms.Form的新实例，而不是我的表单......它通过查看你的代码帮助我看到我的
错误。谢谢，

如果您参考主表单的实例
模块可用，您可以这样做。
提供对应用程序主表单的引用

Why can''t I call a public function or sub defined in the main form of my
application from within a module or a class, all being a part of the
same assembly?
When I define public function in a class, I can call it from the form,
but if I define public function in the form and try to call it from the
class it does not work. Any idea what am I doing wrong?
Thanks,
Strah

You can, but you need to have an instance of the class to call it on, unless
it''s a shared method.
//SomeModule
Dim F as New Foo
F.SomeSub <--This works fine
//SomeBadModule
F.SomeSub <-- Only works if Shared
Class Foo
Public Sub SomeSub()
End Sub
End Class
Hope this clears it up.

Hi Chris,
Your input helped. I was creating new instance of the
Windows.System.Forms.Form instead of my form... it helped me to see my
error by looking at your code. Thanks,
Strah

You can do that if you make a refernece to the main form''s instance
available to the module.
