我用C＃编写文字处理程序，但不是用英文编写。 我想使用颜色对话框，但我想将颜色对话框中的单词更改为另一种语言，我该怎么办？
答案 0 :(得分：1)
我意识到这是一个古老的问题但是如果其他人需要对此做出回答，您可以使用几个不同的winapi调用来更改颜色对话框的文本。以下是一些示例C＃代码。
注意：由于“基本颜色：”和“自定义颜色：”标签由相同的控件ID引用，因此找到“自定义颜色：”标签的句柄是一种相当间接的方法已实施。如果颜色对话框上的所有控件ID都是唯一的，那么“自定义颜色：”标签文本可以像其他控件一样轻松设置。

对话框将使用用户安装的操作系统的语言。
没有办法手动定义语言的本地化语言。
如果你仍然想要它，你必须自己构建一个，或者使用Telerik组件之类的组件并自己进行本地化。那些组件虽然不是ceeap ..
