检索窗口句柄然后按下按钮编程方式 [英] Retrieve Window Handle and Press Button Programatically

问题描述

我敢肯定，这是可能以某种方式，但不知道是否有一个数太多箍跳通过，使其值得的，希望有人会指出我在正确的方向。我有一个问题（与安装程序），由此我相当有规律，我需要按取消有一个对话框弹出。

I'm sure this is possible somehow, but not sure if there are a few too many hoops to jump through to make it worthwhile, hoping someone might point me in the right direction. I've got a problem (related to an installer) whereby I have a dialog popup quite regularly which I need to press cancel on.

我想怎么办接近它编程/通过服务也许因此它在我的方式得到停止（假设我不能修复的根本问题）。所以，我想知道是，如果有一种方法可以抓住一个手柄以某种方式的窗口（检查它是正确的，也许这样做在标签上的文本比较），然后在窗口中定位控制（取消按钮），并发送事件呢？

What I'd like to do is close it programatically/maybe via a service so it stops getting in my way (assuming I can't fix the root issue). So, what I'm wondering is if there is a way to grab a handle to the window somehow (checking it's correct maybe by doing a text comparison on the label), then locating a control on the window (cancel button) and sending an event to it?

如果有谁知道我怎么可能做到这一点还是有些新手那简直太好了。

If anyone knows how I might achieve this or some starters that'd be great.

推荐答案

两种方法可以做到这一点：

Two ways to do this:

• 要获取句柄，当你谈论一个窗口，使用 FindWindow函数API 的，那么你就必须列举与之相关的控件处理，并发送消息WM_BUTTONDOWN，WM_BUTTONUP在一起，通过使用 SendMessage函数。


• 但更简单的方法存在，假设取消按钮被称为 btnCancel ，那么这将足以 btnCancel。点击（）。

• To get the handle, when you talk about a window, use the FindWindow API, then you would have to enumerate the controls associated with that handle, and send a message WM_BUTTONDOWN, WM_BUTTONUP together to simulate a mouse click via using a SendMessage.
• But the simpler method exists, suppose the cancel button is called btnCancel, then this would suffice btnCancel.Click().

除非我错了，你是在谈论一个过程的一个窗口，是不是你的，那么我的第一个建议做。既然你不说，如果你是在谈论自己的应用程序或进程的窗口，是不是你的...那么奥利弗的建议可能会更容易...

Unless I am mistaken, that you are talking about a window of a process that is not yours, then my first suggestion would do. Since you did not say, if you are talking about your own application or a process's window that is not yours...then Oliver's suggestion might be easier...

不过，这引出了一个问题：为什么你要这么做，你是假设有一个取消按钮某处...

But that begs the question: why would you want to do that as you are assuming there is a Cancel button somewhere...

希望这可以帮助，
