  • Changing Text colour in text field by dropdown menu - Visual Studio 2008

    - by Wayne
    Hey, i'm just doing some testing on Visual Studio 2008, what i'm trying to do is to change the text colour inside the multi-textfield which isn't working and I don't know why... Public Class Form1 Dim ColourValue As Color Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load rbBlue.Checked = False rbRed.Checked = False rbGreen.Checked = False End Sub Private Sub rbRed_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles rbRed.CheckedChanged txtSpace.BackColor = Color.Red End Sub Private Sub rbBlue_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles rbBlue.CheckedChanged txtSpace.BackColor = Color.Blue End Sub Private Sub rbGreen_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles rbGreen.CheckedChanged txtSpace.BackColor = Color.Green End Sub Private Sub cbColours_SelectedValueChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles cbColours.SelectedValueChanged ColourValue = cbColours.SelectedValue txtSpace.BackColor = ColourValue End Sub End Class Basically i have the radio buttons that would change the background colour of the textfield, but i just need the dropdown menu to change the text colour. Many thanks :)

  • Super Noob C++ variable help

    Ok, I must preface this by stating that I know so so little about c++ and am hoping someone can just help me out... I have the below code: string GoogleMapControl::CreatePolyLine(RideItem *ride) { std::vector<RideFilePoint> intervalPoints; ostringstream oss; int cp; int intervalTime = 30; // 30 seconds int zone =ride->zoneRange(); if(zone >= 0) { cp = 300; // default cp to 300 watts } else { cp = ride->zones->getCP(zone); } foreach(RideFilePoint* rfp, ride->ride()->dataPoints()) { intervalPoints.push_back(*rfp); if((intervalPoints.back().secs - intervalPoints.front().secs) > intervalTime) { // find the avg power and color code it and create a polyline... AvgPower avgPower = for_each(intervalPoints.begin(), intervalPoints.end(), AvgPower()); // find the color QColor color = GetColor(cp,avgPower); // create the polyline CreateSubPolyLine(intervalPoints,oss,color); intervalPoints.clear(); intervalPoints.push_back(*rfp); } } return oss.str(); } void GoogleMapControl::CreateSubPolyLine(const std::vector<RideFilePoint> &points, std::ostringstream &oss, QColor color) { oss.precision(6); QString colorstr = color.name(); oss.setf(ios::fixed,ios::floatfield); oss << "var polyline = new GPolyline(["; BOOST_FOREACH(RideFilePoint rfp, points) { if (ceil(rfp.lat) != 180 && ceil(rfp.lon) != 180) { oss << "new GLatLng(" << rfp.lat << "," << rfp.lon << ")," << endl; } } oss << "],\"" << colorstr.toStdString() << "\",4);"; oss << "GEvent.addListener(polyline, 'mouseover', function() {" << endl << "var tooltip_text = 'Avg watts:" << avgPower <<" <br> Avg Speed: <br> Color: "<< colorstr.toStdString() <<"';" << endl << "var ss={'weight':8};" << endl << "this.setStrokeStyle(ss);" << endl << "this.overlay = new MapTooltip(this,tooltip_text);" << endl << "map.addOverlay(this.overlay);" << endl << "});" << endl << "GEvent.addListener(polyline, 'mouseout', function() {" << endl << "map.removeOverlay(this.overlay);" << endl << "var ss={'weight':5};" << endl << "this.setStrokeStyle(ss);" << endl << "});" << endl; oss << "map.addOverlay (polyline);" << endl; } And I'm trying to get the avgPower from this part: AvgPower avgPower = for_each(intervalPoints.begin(), intervalPoints.end(), AvgPower()); the first part to cary over to the second part: << "var tooltip_text = 'Avg watts:" << avgPower <<" <br> Avg Speed: <br> Color: "<< colorstr.toStdString() <<"';" << endl But of course I haven't the slightest clue how to do it... anyone feeling generous today?

  • Different background colors for the top and bottom of a UITableView

    - by Aaron Brethorst
    If you look at your Inbox in iPhone OS 3.0's Mail app, you'll see that swiping down displays a grayish background color above the UISearchBar. Now, if you scroll down to the bottom of the table, you'll see that the background color at that end is white. I can think of a couple ways of solving this problem, but they're pretty hacky: Change the table view's background color depending on the current scrollOffset by overriding -scrollViewDidScroll: Give the UITableView a clear background color and then set its superview's backgroundColor to a gradient pattern image. Does anyone know what the "best practice" solution is for this problem? thanks.

  • Can't get screen pixel from a specific full screen game with any language?

    - by user1007059
    Okay, I know this might seem like I'm posting a duplicate question since I've asked something similar like a day ago HOWEVER, if anyone sees any problem with this, please read my question first before judging: Yesterday I tried getting a specific pixel from a fullscreen game in C#. I thought my C# code was faulty but when I tried with multiple full screen games today they all worked except for that specific game. I literally tried with 10 different full screen games, a couple being mmofps, mmorpg, mmotps, regular rpg games, regular shooters, regular action adventure games, etc. I tried with multiple programming languages, and with every game except that specific game I'm dealing with, it returns the pixel color to me like I wanted. So let me explain what I tried: first I tried returning an IntPtr with C# using GetDC(IntPtr.Zero) before invoking GetPixel(int x, int y) and then getting the color out of it. Then I tried using the Robot class in Java and using the getPixelColor(int x, int y) method. I also tried using GetDC(0) to return an HDC object in C++ and then invoking GetPixel(int x, int y) before again extracting the color. These three methods worked EXACTLY the same in every single game except that specific game I was talking about. They returned the pixel perfectly, and extracted the exact same color perfectly. I don't feel it's necessary to tell you the game name or anything, since you probably don't even know it, but what could possibly be causing this malfunction in 1 specific game? PS: The game ALWAYS returns an RGB color of: A = 255, R = 0, G = 0, B = 0. Also, I tried taking a snapshot of the game with the 3 programming languages, and then getting the pixel which actually works in all 3 languages, but since I need to get this pixel every 30 ms, it kind of makes my game lag a bit (+ I think it takes up a lot of memory)

  • div content margin pushing container

    - by jef2904
    Hi, Im running into an issue that's really baffleing me. I have a container that I want to apply a background to an postion it in the top right of the browser screen. The div inside has a top margin of 4em and this is pushing the container div here is the CSS #container { background: transparent url("../images/house-bg.png") top right no-repeat scroll; } #wrapper { background: #FFF; width: 960px; height: 600px; margin: 4em auto 0; border: 10px solid #C3CF21; -moz-border-radius: 20px; -webkit-border-radius: 20px; border-radius: 20px; -moz-box-shadow: 0 0 25px #444; -webkit-box-shadow: 0 0 25px #444; box-shadow: 0 0 25px #444; } and heres the HTML <div id="container"> <div id="wrapper"> <div id="header"> </div> <div id="main"> </div> </div> <div id="footer"> &copy; Copyright <?php echo date("Y");?> Company, Inc. </div> </div> I want the margin of the wrapper to be inside the container div instead of outside. I've tried multiple display properties and position properties to no avail. The only thing that fixes it is inserting an "&nbsp;" before the start of the #wrapper but theres got to be a CSS fix to this. Thanks in Advanced, Jorge

  • Why doesn't CSS support constants?

    - by Adiel Mittmann
    CSS has never supported constants or variables directly. Whenever I'm writing code like this: span.class1 { color: #377fb6; } div.class2 { border: solid 1px #377fb6; /* Repeated color */ } I wonder why such a seemingly simple feature has never made it into the standard. What could be hard about implementing a scheme whereby we could avoid repetition, something like this: $theme_color1: #377fb6; span.class1 { color: $theme_color1; } div.class2 { border: solid 1px $theme_color1; } I know there are workarounds, like using a class for each color or generating CSS code from templates, but my question is: given that CSS is so rich and complex, why weren't CSS constants ever introduced?

  • Selective coloring on dynamic TextBlock content in WPF

    - by user326579
    For selective coloring of static content the following suggestion works fine : http://stackoverflow.com/questions/2435880/is-it-possible-to-seletively-color-a-wrapping-textblock-in-silverlight-wpf However my content will be generated at runtime. For ex. if the Content generated is : "A Quick Brown Fox" Then I need they string "Brown" to be in color Brown and "Fox" to be in color Red The Keyword-Color list is fixed and available to me at runtime. I have looked at the Advanced TextFormatting page on MSDN, but it is too complicated for me, also the sample in there does not compile :( I am looking at creating a custom control which can do this for me. Let me know if anyone has any idea regarding how to go about this. Thanks in advance.

  • How to adjust font size with Cufon?

    - by user77413
    I am using a condensed font in Cufon. When the page loads, my menu is too wide and wraps. Then Cufon replaces the font and it looks fine. To reduce the visual distraction, I want to set the font size smaller and then have Cufon change the font size when it displays. Currently the font size is set by the div containing the menu. Here is the CSS for the menu container: .header_menu_block { display: block; margin: 0px 0px 0px 0px; padding: 0px 0px 0px 0px; margin-top: 3px; /*margin-left: 238px; ie 6 can't handle, see margin block below*/ float: left; text-align: left; font-weight: normal; font-size: 14px; color: #FFFFFF; height: 41px; width: 991px; } The Cufon replacement code looks like this: <script type="text/javascript"> Cufon.replace('.header_menu_block_col_menu ', { color: '#ffffff', hover: {color: '#204966'} } ); </script> I've tried setting the CSS font size to 12px and then using the following Cufon code, but it does not work: <script type="text/javascript"> Cufon.replace('.header_menu_block_col_menu ', { color: '#ffffff', hover: {color: '#204966'}, font-size:'14px' } ); </script> Does anyone know how to do this?

  • Odd problem with IE8 and z-index CSS property

    I not been able to put one DIV over his parent DIV in Internet Explorer. With Firefox is working as suposed to. The odd part is that if I open the html file directly in IE, everything works fine. But if I upload to the server and open from there, the div is hidden underneath his parent. I've tried several z-index combinations and none works. Here's the code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head> <title>Test</title> <meta http-equiv="content-type" content="text-html; charset=utf-8" /> <style type="text/css"> .col { float:left; width:310px; margin-right:13px; } .art { position:relative; border-bottom: 1px solid #d0d0d0; font: normal normal bold 11px Arial,Verdana,Helvetica; color:#A0A0A0; width:310px; height:50px; top:0px; left: 0px; margin-right:10px; background-color:#F0F0F0; } .art a { padding:3px; display:block; width:304px; height:100%; color:#707070; } .art a:visited { color:#A0A0A0; } .art a:hover { background-color:#E0E0E0; } .box { z-index:1000; background-color:#A0A0A0; color:#404040; font: normal normal bold 11px Arial,Verdana,Helvetica; display:none; position:absolute; top:30px; left:10px; text-align:left; border:3px solid #707070; margin:5px 0px 5px 5px; font-size:10px; color:White; width:100%; } </style> <script type="text/javascript"> function sh(obj) { var el = document.getElementById(obj); if ( el.style.display != 'block' ) { el.style.display = 'block'; } else { el.style.display = 'none'; } } </script> </head> <body> <div class="col"> <div class="art"> <a href="" target="_blank" onmouseover="javascript:sh('i0')" onmouseout="javascript:sh('i0')">Title 1</a> <div id="i0" class="box"> <div class="text"> Les "chemises rouges" manifestent depuis la mi-mars pour faire tomber le gouvernement et occupent depuis trois semaines un quartier touristique et commerçant autour duquel ils ont érigé des barricades. </div> </div> </div> <div class="art"> <a href="" target="_blank" onmouseover="javascript:sh('i1')" onmouseout="javascript:sh('i1')">Title2</a> <div id="i1" class="box"> <div class="text"> Une association ardéchoise accueillant des séminaires de "bien-être" et de "développement personnel" a refusé d'accueillir un stage de danse en invoquant l'homosexualité des participants, ont indiqué aujourd'hui les organisateurs. </div> </div> </div> </div> </body> </html> What's is going on here?

    - by Jean
    Hello, I have 2 nested divs, both have #x{ width:400; height:400px; background-color:#fff; color:#000 } #y{ width:200; height:200px; background-color:#000; color:#ccc; } <div id="y"><div id="x">Here lies a x value</div></div> I want the #x and #y to have individual css properties, but that is not the case, #x overrides the #y values Any help appreciated. Thanks Jean
