Printing Question - characters per line
-
Hi Guys, I am trying to print some items from a listview. I read the whole listview item in a String and then i try to see how many characters i can write on a line of the page that i want to print one :
public void pd_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
{
...
float characterPerLine = e.MarginBounds.Width/printFont.GetHeight(e.Graphics);
...
}but this is not returning me the correct number. The question is ... how can i calculate the number of characters per line when printing? Kind regards, Alex

Sooo you're dividing the width by the height of a character to get the number of possible characters?? You don't see a problem with that?? Wouldn't you divide the width the page by the width of a character to get that?? BTW, the math you've chosen only work with fixed-width fonts. It will not return an accurate value for a proportional width font (which most fonts are!)

Hi, as an approximation you could come up with an "äverage string" of say 100 characters, then feed it to e.Graphics.MeasureString and get the returned Width. if you need an (almost) exact value, you should use MeasureString for each actual string that interests you. The "(almost)" refers to a CP article on some minor anomalies, the result being of by a few pixels. :)

2006, 2007, 2008Sorry , you are right , my bad. i tried this :
float characterPerLine = e.MarginBounds.Width/printFont.Size;and it worked. but it still is not einough... I know that i shoud devide the widith of the line with the widith of the font but there is no printFont.GetWidith in c# intelisense.“Be the change you want to see in the world.”

That is a hint, I suppose... :rolleyes:

There is no printFont.GetWidth in C# for a very good reason. It doesn't make any sense. Since most windows fonts are proportional there is no fixed width of a character. I.e. an 'i' character is a lot narrower than a 'W'. If there is no fixed character width in a font, you can't have a method which returns the width of a character.
