挑战？

本文介绍了挑战？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

这对我来说真的是一个挑战。 我在VB.NET 2003中开发的应用程序在海船上运行， 应用程序有很多屏幕和控件。在晚上的海上船上，只有 暗青色（或类似）颜色必须在显示器上使用（很像雷达 显示）否则船长将被蒙蔽明亮的颜色。 在晚上，用户点击按钮将应用程序转换为 夜间模式。我不想通过所有对象（超过1000）来改变每种颜色，我想也许我可以更改 Windows或VB的调色板，他们正在使用的计算机被指定只运行我的 应用程序，所以它不会影响其他应用程序。 有没有办法我可以更改例如 SystemColors.Control.Yellow在夜间模式下对SystemColors.Control.DarkCyan的定义 并在日模式下恢复正常？ 谢谢提前。

this one is really a challenge to me. the application i developed in VB.NET 2003 runs on marine boat, the application has many screens and controls. On a marine boat at night, only dark cyan (or similar) color must be used on display (much like the radar display) otherwise the captain will be blinded by the bright colors. When at night, the user clicks on a button to turn the application into night mode. I do not want to go through all the objects (over 1000) to change each color, I am thinking that maybe I can change the palette of Windows or VB, the computer they are using is designated to run my application only, so it will not affect other application. Is there a way i can change for example the definition of SystemColors.Control.Yellow to SystemColors.Control.DarkCyan at night mode and return to normal on day mode? Thanks in advance.

鉴于您的应用程序仅使用PC，听起来最简单的方式 将确保所有控件都使用SystemColors，然后更改 * global * Windows配色方案（你知道，你在哪里设置什么颜色 标题栏和东西是）。我只是做了一个快速测试，并且当Windows 配色方案发生变化时，在Win2k上运行的VB.NET 2002 应用会自动*更改颜色*所以你应该没问题。 现在问题变成了如何更改Windows设置？我怀疑 它将涉及P / Invoke''的API，但我不希望它是特别困难的b / b 。您可以自己找到，或者您想要更多？ - Larry Lard 回复团体请

Given that your app has sole use of the PC, sounds like the easiest way would be to make sure all your controls use SystemColors, then change the *global* Windows colour scheme (you know, where you set what colour title bars and stuff are). I just did a quick test and a VB.NET 2002 app running on Win2k changes colours *automatically* when the Windows colour scheme changes, so you should be alright. Now the question becomes how to change that Windows setting? I suspect it will involve P/Invoke''ing the API, but I don''t expect it to be particularly difficult.

[回复自己] （它是SetSysColor但是... ） 实际上，为什么重新发明轮子？只要确保你的应用只使用 SystemColor'的颜色，那么用户就可以使用控制面板 |显示在晚上切换到夜间计划，并且（因为我建立了）你的应用程序将自动切换。 - Larry Lard 回复团体请

[replying to self] (it''s SetSysColor but...) Actually, why re-invent the wheel? Just make sure your app uses only SystemColor''s for its colours, then the user can just use Control Panel | Display to switch to a night-time scheme at night, and (as I have established) your app will switch automatically. -- Larry Lard Replies to group please
