关闭(并选择保存)所有屏幕 [英] Close (and Optionally Save) All Screens

问题描述

使用易于扩展的扩展程序，我添加了全局关闭所有屏幕"命令，如下所示:


但是，当我使用从"currentScreen"中更改参数时.关闭(假)"到"currentScreen.Close(True)"，它应该每个 屏幕提示用户保存，如果我有多个需要保存的屏幕，应用程序将崩溃，从而使我只有无响应的纯白色屏幕.
我怀疑是由于close命令在由于存在单独的线程，因此正在发生某种竞争状况，但是 我不知道如何解决.

有人有任何想法吗?

谢谢！

我可以建议您检测出待处理的更改并自己提示用户，然后使用'.Close(false)'.

如果无法使用线程/调度程序来解决技术问题，那就去吧.

Using Extensions Made Easy, I've added the global "Close All Screens" command, as per here:

Adding custom commands, global commands and new command groups to the LightSwitch button ribbon

But when I use the change the parameter from "currentScreen.Close(False)" to "currentScreen.Close(True)", which should have each screen prompt the user to save, if I have multiple screens which need saving, the app crashes, leaving me with just an unresponsive pure white screen.

I suspect that this is happening because the close command runs in a seperate thread and some kind of race condition is occuring because of it, but I do not know how to fix it.

Anybody got any ideas?

Thanks in advance!

解决方案

May I suggest you detect the pending changes and prompt the user yourself, then use '.Close(false)'.

If you cannot sort out a technical way with threads/dispatchers then go for that.

Cheers
