c# - format number with 3 trailing decimal places, a decimal thousands separator, and commas after that -


this simple question, , i'm sure there's way string.format(), numberformatinfo, cultureinfo or combination of them, need display large numeric values 3 trailing decimal places, decimal instead of comma thousands separator, , comma millions separator , up.

the input either whole number or number followed 3 decimal places (20000, 123.456, 12.2)

for example:

142650 should display 142,650.000

11200.50 should display 11,200.500

123.456 should remain 123.456

i suppose it's same dividing value 1000 , using string.format("{0:f3}", value), hoping find didn't take arithmetic.

string.format("{0:#,#.000}", value) gets me close, puts leading 0 on small numbers, 1.256 displaying 01.256, when need remain 1.256

the format string.format("{0:#,0.000}", value) ended doing me. works whole numbers , numbers anywhere 1 3 trailing decimal places.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...

c++ - qgraphicsview horizontal scrolling always has a vertical delta -

Image
i've subclassed qgraphicsview custom canvas used in cad application. i've reimplemented qgraphicsview::wheelevent check keyboard modifiers control key and, if control key pressed, zoom. i'm trying implement horizontal scroll when user holds shift , uses wheel. the problem i'm having horizontal scrolling always scrolls 0.279. not huge problem, hugely annoying , points else being wrong. so, here questions: is right way implement horizontal scrolling? if not, is? how eliminate delta of 0.279? thanks in advance. code , sample output below void myview::zoom(int delta) { double factor = pow(1.2, delta/abs(delta)); this->scale(factor, factor); } void myview::scrollhorizontal(int level) { qpointf center = maptoscene(viewport()->rect().center()); qdebug() << "center: " << center.x() << ", " << center.y(); centeron(qpointf(center.x() - level, center.y())); } void myview::wheelevent(qwheeleve...
