Wrapping Text in a rich textbox, but not word wrapping it

由 拥有回忆 提交于 2019-12-01 06:00:57
I have a Windows Form with a Rich Textbox control on the form. What I want to do is make it so that each line only accepts 32 characters of text. After 32 characters, I want the text to flow to the next line (I do NOT want to insert any carriage returns). The WordWrap property almost does this, except that it moves all the text entered, up to the last space in the text and moves it all. I just want to neatly wrap the text right after 32 characters. How can I do this? I'm using C#. Ok, I have found a way to do this (after a lot of googling and Windows API referencing) and I am posting a

transparent richTextBox

由 随声附和 提交于 2019-12-01 04:26:06
how can I make my richtext box transparent I want this cuz I am trying to put a text on top of a graphic image (which is the background of my form). That is why I wanted the richTextBox to be transparent, I am using .NET ,c# and in a windows form application There is no such thing as true transparency in a WinForms Control. Transparent mode inherits the default background of its parent.

I know this answer is very late, but I hope it
