初始化/声明代表 [英] Initalizing / declaring Delegates

问题描述

可能是一个愚蠢的问题，但我认为我最好与专家确认:-)

过去，我在一个单独的模块中初始化/声明了委托，从而使他们可以在整个解决方案中访问

Probably A stupid question but I think I better check with the experts :-)

In the past I have initialized/ declared delegates in a separate module making them accessible throughout the whole solution

Delegate Delegate_NO_parameter()

然后，我在代码中的很多地方(不同的模块/表单)一直使用 same 委托

Then, I have been using this same delegate in numerous places in my code (different modules / forms)

Sub 1 ()
   Dim d As New Delegate_NO_parameter(AddressOf X) 
   Me.Invoke(d)
End sub

Sub 2 ()
   Dim d As New Delegate_NO_parameter(AddressOf Y) 
   Me.Invoke(d)
End sub

现在我知道这可能不是这样做的正确方法，但是到目前为止，我从未遇到过麻烦-直到现在...

这样做是否有可能使回调函数得到交叉引用=而不是调用 Sub X ，如果两者都在相同时间
我认为它不应该-但是在我的代码中，我仅通过移动"类似的回调就可以解决几天来困扰我的问题?

Now I know this might not be the proper way of doing so but so fare I''ve never had an issue with it - until now ...

Is it possible that by doing so, the callback''s could get cross referenced = instead of calling Sub X it might call Sub Y if both get invoked at the "same" Time
I don''t think it should - but in my code I was able to fix an issue that has been bugging me for days by just "moving" similar callbacks around a bit ???

推荐答案

什么是代表?

What are Delegates?

我搞砸了-我的工作线程中的timer_tick搞砸了全局变量
=移动代码只是改变了时间=导致结果不一致

-我将像过去一样继续使用代理人:-)

I messed up -a timer_tick in my worker thread was messing with a global variable
= moving code around just changed the timing = resulting in inconstant results

- I''ll keep using delegates as I have in the past :-)
