创建“附加"窗口.反对“实例"? [英] Creating windows "attached" to object "instances"?

问题描述

再见.

我有一个Com服务器DLL，该窗口仅供我参考
从Windows消息队列中检索消息的过程.窗口是在其他线程中创建的.我从codeguru.com上的帖子中获得了此代码.

这很好用.并提供了我所追求的IPC.是的.

但是，我想要的是将单独的窗口附加到类工厂中创建的对象实例"上(因为缺少更好的词).尽管可以尝试，但我不太了解需要更改的内容.

现在，当我希望有一个新窗口与第一个窗口分开时，更改的每个对象实例都将更改相同的可见窗口的名称，以反映当前对象实例ID.

在我看来，如果可以动态更改窗口结构的名称
请在可能会这样做的每个创作上命名.

这是窗口代码.

WindowName是指向创建的对象实例名称的指针，该对象实例名称是在
上创建的 对象创建时间.一旦一切正常，我会将窗口更改为不可见消息，仅显示窗口
可以通过窗口名称找到谁. (对象实例ID).

提前谢谢.

Hi again.

I have a Com server DLL that I have given a window to that is for the sole purpose
of retrieving messages from the Windows message queue. The window is created in a different thread. I got the code for this from a post over at the codeguru.com

This works nicely. And provides the IPC I was after. Yay.

What I would like however, is individual windows attached (for lack of a better word) to object "instances" that are created in the classfactory. While I could try and try, I don''t quite know what I need to change.

Right now with each instance of the object created the same visible window''s name is changed to reflect the current object instance ID, when I expected a new window separate and apart from the first.

It seems to me that if I could dynamically change the name of the window structure
name upon each creation that might do it, maybe not.

Here is the window code.

WindowName is a pointer to the created object instance name that is created upon
object creation time. Once it is all working I will change the windows to be invisible message only windows
who will be found by the window name. (object instance ID).

Thanks in advance.

推荐答案

每次调用CreateWindow()时，您正在创建一个窗口的独立实例...因此，如果要创建一个单独的实例在一个类中，然后只需在该类的任何非静态成员方法中执行即可.

Every time you call CreateWindow() you''re creating an independent instance of a window... so if you want to create a separate instance within a class, then just do it within any non-static member method of the class.
