FontStyle Question

[Sammut]

Hi,

I have started using the RichTextBox and got a bit stuck on the fontstyle
This is my current code

System.Drawing.Font fCurr = richTextBox1.SelectionFont;

System.Drawing.FontStyle nCurr = new FontStyle();



if (fCurr.Bold) nCurr = nCurr | FontStyle.Bold;

if (fCurr.Underline) nCurr = nCurr | FontStyle.Underline;

if (!(fCurr.Italic)) nCurr = nCurr | FontStyle.Italic;

is there any easier way to do this by getting the Current font style and add or remove what is needed



and also what does the "|" stand for and what is it's opposite if there is?



Thanks

Ivan Sammt

"|" is the operator for bitwise OR.it combines the bits with those in the target variable.

To reset the bits you have to use a bit-mask with the bits you want to zero set to zero. For example, to turn off bold you would do this...

nCurr=nCurr & (FontStyle.Bold ^ 0xffffffff)

#1-------------^^^^^^^^^^^^^^^^^^^^^^^^^^^ Flips the bits in the fontstyle
#2----------^ bitwise AND of the mask and the original

(view this in courier or any monospace font)
