html - Table Row, can you set the height to zero? -

Can you set table row height to 0? IE 8, Chrome, Firefox, Opera

Why, you ask! OK, I have a line that is dynamically created and displayed when a user clicks on a basic line. The problem is that if there are no rows, then when clicked, it is still an empty 1 pixel Highline displays.

This child gridview: 

  & lt; Asp: TemplateField HeaderStyle-CssClass = "hidden-column" item style- CssClass = "hidden-column" footer-CSS class = "hidden-column" & gt; & Lt; ItemTemplate & gt; & Lt; TR & gt; & Lt; Td colspan = "8" & gt; & Lt; Div id = '& lt;% # Eval ("PublicationID")%> & gt; Style = "display: none; condition: relative;" & Gt; & Lt; Asp: GridView id = "GridView2_ABPubs" runat = "server" AutoGenerateColumns = "false" width = "100%" DataKeyNames = "PublicationID" font-name = "Wordana" font-size = "small" & gt; & Lt; Columns & gt; & Lt; ASP: TemplateField & gt; & Lt; ItemTemplate & gt; & Lt; ASP: Checkbox ID = "Childbank Selection" Runat = "Server" /> & Lt; / ItemTemplate & gt; & Lt; / ASP: TemplateField & gt; & Lt; ASP: Boundfield Dated Field = "Name Abreb" Header Text = "Publication Name" Sorted Expression = "Name Abrev" /> & Lt; / Column & gt; & Lt; / ASP: GridView & gt; & Lt; / Div & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt; / ItemTemplate & gt; & Lt; / ASP: TemplateField & gt;

CSS: 

  .hidden-column {display: none; }

Javascript: 

  & lt; Script language = "javascript" type = "text / javascript" & gt; Var presentAprididDiv = ""; Function collapseExpand (object) {var div = document.getElementById (object); // if (currently active! = "" & Amp; amp; amp; amp; currently active DIV! = Div) // // currently running DIVI.style. Display = "none"; //} if (div.style.display == "none") {div.style.display = "inline"; Currently diode = div; } And {div.style.display = "none"; }} & Lt; / Script & gt;

I do not think the 0-line-height move works perfectly, However - with Firefox and IE it creates a thick border at the top of the table, if you close the borders it does not matter to you (although I think you still have a blank 1 pixel row at the top of the table ). Many web designer spacer uses GIF (a 1x1 transparent gif, which is the size of the size of the appropriate width) to get the same effect which both problems solve

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...
