javascript - Maximum width/height canvas scrollbar interference? -

-

I'm trying to get 100% width, height canvas element to attract, but because I grab 22 Chrome and Firefox both make scrollbar. The scrollbar appears here because the other related scrollbar makes the content longer / longer. That is, the vertical scrollbar is there because the bottom of the canvas is covered by the horizontal scrollbar and the horizontal scrollbar is there because the canvas right is covered by the vertical scrollbar. Any help is appreciated. 

  & lt ;! DOCTYPE html public "- // W3C // DTD XHTML 1.0 Strongly //n" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> & Lt; Html xmlns = "http://www.w3.org/1999/xhtml" lang = "en" xml: lang = "en" & gt; & Lt; Top & gt; & Lt; Script type = "text / javascript" src = "js / jquery.js" & gt; & Lt; / Script & gt; & Lt; Style & gt; * {Margin: 0; Padding: 0; } & Lt; / Style & gt; & Lt; Script type = "text / javascript" & gt; $ (Document) .ready (function () {var canvas = $ ("canvas"). Get (0); canvas.width = $ (document) .width (); canvas.height = $ (document). ); Var c = canvas.getContext ("2d"); c.fillStyle = "rgb (200,0,0)"; c.fillRect (0,0,5000,50); c.fillStyle = "rgba (0 , 0,200,0.5) "; c.fillRect (0,0,50,5000);}); & Lt; / Script & gt; & Lt; / Head & gt; & Lt; Body & gt; & Lt; Canvas & gt; & Lt; / Canvas & gt; & Lt; / Body & gt; & Lt; / Html & gt;    
 
 
 Did you  & lt; Body & gt; ? By default, it comes with some padding and margins, so if you have content that is "completely" fit, scrollbars will be because the padding and margin push the size.

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
