word-wrap

Hi,

Happy New Year!

I have a textbox to display a very long Base64 string. The TextBox.Multline = true and TextBox.WordWrap = true.

The issue is caused by the auto-word-boundary detection of the TextBox itself. The Base64 string has '+' as one of the 64 characters for Base64 encoding. Therefore, the TextBox will wrap it up at the '+' character, which is not what I want (because the use might think there is a newline character around the '+' character).

I just want my Base64 string displayed in Mulitline-mode in TextBox, but no word boundary detection, that is, if the TextBox.Width can only contain 80 characters, then each line should have exact 80 characters except the last line.

I'm not sure if I made myself clear.

Thanks.

Peter

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language.

In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
