TX Text Control has built-in dialog boxes and error strings. The language used for the built-in TX Text Control resources depends upon the current system language. For example, if a developer builds a satellite assembly for Chinese, the Chinese resources are only loaded, if the current system or thread UI language is also Chinese.

We have just released simplified Chinese dialog box resources for TX Text Control .NET for Windows Forms 15.1. You can download these and other resources on this dedicated website section:
