到达表单C＃（WinForm）末尾时在下一行继续的文本

Question

So i want to make a WinForm app that will start typing text from the upper left corner all the way to the lower right corner like a console application, when it reaches the end of a line it continues in a new line.

eg:

>line 1:     I need y
>
>line 2:     our help

The text should be chopped, if you get what i mean.

Answer 1

You should use RichTextBox for this purpose. It represents a rich text control that supports formatted text, hyperlinks, inline images, and other rich content.

RichTextBox.TextWrapping Property of RichTextBox can help you.

• It gets or sets how text wrapping occurs if a line of text extends beyond the available width of the RichTextBox .
• You should consider the width of the RichTextBox when you set the TextWrapping property.
• Any text that extends beyond the bounds of the RichTextBox will not be displayed. If the TextWrapping property is set to NoWrap , text that exceeds the horizontal bounds can be scrolled into view using the cursor. Text that exceeds vertically can be scrolled into view using the keyboard or scrollbar.
• If the TextWrapping property is set to Wrap, the HorizontalScrollBarVisibility property is automatically set to Disabled and any property changes to the HorizontalScrollBarVisibility are ignored.

Answer 2

You can use MultiLine Textbox .. you have to notice that

[1] Will be easier if you use fix width fonts .. this the idea (not real code)

charlimit = me.width / textwidth("A") ----> use graph textrender function here

[2] You can control textbox_textchanged event to ensure that the word not get ' autowrap ' to next line .. so when the text position is in most right position you can chop it by add the text with vbCrLf ..

if LastLine.Length = charlimit then

     alltext += vbCrLf

     lastLine = ""

endif

But this would be hard when you do in middle row because you have to reccount the words after it (below it) ..
