• G210M Screen brightness control issue

  - by Bapun

  I have a Sony VAIO VPCCW15FG laptop with NVIDIA G210M graphics card. I can't adjust the screen brightness! If I use the Fn shortcuts the brightness notification shows-up and there the brightness changes the level but nothing happens. I was able to adjust the brightness level in ZorinOS. But nothing happens when I changed the bright level, then brightness level changes radically with each step in the last stages.

• opengl memory issue - quite strange.

  - by user4707

  Hello, I have heard that textures consumes lot of memory but I am surprised how much.... I have 7 textures 1024 16 bit each. And while I will run my app it consumes 57MB of memory. I think that this is "a bit" too much. I am writing 2D application (no cocos or other framework) Strange is that while I will compile my app with disabled rendering methods: glDrawArrays than It uses only 27MB.... which is about 30MB less... Do you have any Idea why? I am creating textures before rendering of course: rendering looks like this: [EAGLContext setCurrentContext:context]; glBindFramebufferOES(GL_FRAMEBUFFER_OES, defaultFramebuffer); glClearColor(0.0f, 0.0f, 0.0f, 1.0f); glClear(GL_COLOR_BUFFER_BIT); glPushMatrix(); glEnableClientState(GL_VERTEX_ARRAY); glEnableClientState(GL_TEXTURE_COORD_ARRAY); glEnable(GL_TEXTURE_2D); glEnable(GL_BLEND); glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA); TeksturaObrazek *obrazek_klaw =[[AppDirector sharedAppDirector] obrazek_klaw]; glBindTexture(GL_TEXTURE_2D, [[obrazek_klaw image_texture] name] ); glVertexPointer(2, GL_FLOAT, 0,vertex1); glTexCoordPointer(2, GL_FLOAT, 0, vertex2); glColor4f(1,1,1,alpha); glDrawArrays(GL_TRIANGLE_STRIP, 0, 4); glDisable(GL_BLEND); glDisable(GL_TEXTURE_2D); glDisableClientState(GL_TEXTURE_COORD_ARRAY); glPopMatrix(); [context presentRenderbuffer:GL_RENDERBUFFER_OES]; It looks like standard routine... I have spent about 2 days looking for for answer and I still have no clue.

• Why CoffeeScript is an issue

  - by Renso

  Other than some obvious concerns, my main concern is support in the open source community. "anon" from the CoffeeScript team sent this to me after I requested input from the team to concerns I raised and wanted to get others' take on it:"Thanks for confirming that only idiots willingly program in Java and C#"or the following from the same person:"Oh and finally, you should definitely create jShort. Even though I know you will fail before you even start, I would love to laugh at your attempts and it would be perfect for you since you ride the short bus. "This kind of comment reflects badly on the CoffeeScript team and hence not an option for us as a company to consider. Another example of why some open-source community projects get no traction.

• Setting up fastcgi on an Ubunutu server (socket file permissions issue)

  - by gray alien

  I am trying to set up mod_fcgid on my server. Part of the requirement is that Apache needs to create a socket file for mod_fcgid. I specified the folder for Apache to write the socket data to: /var/run/apache2/fcgid I then specified this file in my fcgid.conf file as follows: SocketPath /var/run/apache2/fcgid/sock I then changed the owner of the folder to www-data (the apache user) and gave the owner full permissions to the folder and its contents. I was able to run my test fcgi app then. When I rebooted the machine, y fastcgi app no longer worked. After some investigation, I found that ownership of /var/run/apache2/fcgid has been reset to root, and with permission reset to 700 I have the following questions: Is there something specific about the /var/run folder? why is the permissions being reset after a reboot? Should I move my socket file to another location (in case root automatically takes ownership of contents in this folder for security reasons?) I am running Ubuntu 10.0.4 LTS 64 bit

• Windows 7 and Ubuntu Boot issue

  - by user115137

  I had the idea to dual boot Win 7 and Ubuntu and what I did was the following: Made a clean install of win 7 using all of my hard drive, next I used the Ubuntu live cd and gparted to partition my drive to be the following: /dev/sda1 ext4 20GB (Linux root) /dev/sda2 ntfs 100GB(Win7) /dev/sda3 ext4 350GB(Home) /dev/sda4 extended 4GB(swap) The thing is, when installing ubuntu I deleted the partition win 7 creates for its boot sector and recovery and then resized the drive to look like what I mentioned, and Ubuntu installed GRUB to the MBR. When GRUB boots I can see Ubuntu but not Windows, how can I chainload it? Or should I fix the windows mbr with the windows 7 installation disk and try to set the dual boot from there? I don't really care which one of the 2 bootloaders I end up using, I just want the dual boot to work out. Thanks

• When Canonicalization is an Issue

  Although extremely hard to pronounce, canonicalization is a hot topic right now. If there are a lot of URLs that lead to pretty much the same page, you're going to make the search engines work extra hard and spend a lot more time crawling all the different URLs. Often times, this means that they'll miss the important pages of your website because your crawl time is limited or too slow.

• Basic Java drawing program: issue with squares

  - by Caminek

  I'm trying to create a simple drawing program that creates a square where the user clicks and drags. The square displays correctly as long as either x or y remain positive with respect to the original click position. If both x and y are negative with respect to the original click position, the square grows/shrinks, but also wanders about the screen. Is there a way to swap the origin point from top-left to bottom-right or to keep the square from wandering?

• Dual monitor, permission issue

  - by cenna75

  I had a dual monitor configuration going on for quite some time. One day, after moving the computer to another location and reconnecting everything, it changed such that I saw everything in double (being very much sober), I think it's called the 'mirrors' config. Anyway, from there on, there was nothing to be done through the system settings gui to change it back, as it wouldn't allow me to save any modification. The error I get when clicking 'save' is : "Failed to create file /home/me/monitors.xml.xxxxxx. Permission denied", xxxx being a random code, changing everytime. However, I can save all the configurations I want just fine by using the terminal, in my case: xrandr --output DVI-I-1 --right-of VGA-1 So I do have a workaround and this is therefore a question more out of curiosity. What could possibly have changed to make it impossible to do it through the gui and still letting me change the config using xrandr without being root? I'm having a hard time believing it could have anything to do with disconnecting/reconnecting the monitors... Any idea? Thanks !

• Weird internet connection issue on Ubuntu 14.04

  - by user287876

  I have an old Gateway PC with Windows 7 installed alongside the original (XP, I think?). A while ago my friend walked me through and helped me install Ubuntu 14.04 alongside the others because my Win7 was having issues with the display driver (it would unexpectedly crash while trying to watch videos on YouTube or other places). And I can't update it because the original computer settings are for XP or something, not Win7. :( We recently switched from AT&T U-Verse to Comcast. I would have stayed with Ethernet, but somehow the adapter I have wouldn't connect to Comcast's thing during their installation. So I was given a wireless USB adapter. It worked fine, up until the last few days. It's not a problem on Win7 (using it right now). Connection's strong, things load. On Ubuntu though, it SAYS it connects even before I login to my account, but when I login and bring up Firefox, it will load the homepage, and maybe one or two other pages I venture to before suddenly just... endlessly trying to load the page. I would normally go in and manually select 'disconnect' from the connections options menu to refresh/restart it like I've done a few times already. But lately, it won't respond, and then a little while later an error message comes up saying the request timed out/failed. Restarting my computer doesn't help it. The other weird thing is that I've noticed the signal (when it's actually working properly before the last few days) is comparitively weaker than when I'm on Win7. But my location doesn't change. It's the same computer, same connection.

• Sparxsystems Enterprise Architect and issuses/tasks tracking system?

  - by peperg

  We (developement team 4 upto 7 people) use Sparxsystems EA for requirement analysis, modeling etc. Do you know any well-working methods to use EA and some task/issue tracking system like Redmine/Mantis/Trac ? The problem is not to duplicate functionality (there are issues/tasks/changes in Redmine and EA) but to have some user friendly interface (preffered web) to manage tasks and issues. By user-friendly I mean "my tasks" page add effort / time tracking easy "add issue" by everyone (simple bug tracking system) mail notifications

• Good hosted sites to manage quality testing?

  - by Chirag Patel

  Basically, I would like to manage quality testing with an issue management system focused on quality testing? I can't use the typical issue management system such as Lighthouse, FogBugz because each test is written as a ticket and 20 to 30 tickets need to be duplicated (w/ no history) every time we start a quality cycle. Do any (hosted) sites exist? We're currently using a Google Spreadsheet so it can be collaboratively edited.

• WPF Toolkit DataGridCell Style DataTrigger

  - by KrisTrip

  I am trying to change the color of a cell to Yellow if the value has been updated in the DataGrid. My XAML: <toolkit:DataGrid x:Name="TheGrid" ItemsSource="{Binding}" IsReadOnly="False" CanUserAddRows="False" CanUserResizeRows="False" AutoGenerateColumns="False" CanUserSortColumns="False" SelectionUnit="CellOrRowHeader" EnableColumnVirtualization="True" VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Auto"> <toolkit:DataGrid.CellStyle> <Style TargetType="{x:Type toolkit:DataGridCell}"> <Style.Triggers> <DataTrigger Binding="{Binding IsDirty}" Value="True"> <Setter Property="Background" Value="Yellow"/> </DataTrigger> </Style.Triggers> </Style> </toolkit:DataGrid.CellStyle> </toolkit:DataGrid> The grid is bound to a List of arrays (displaying a table of values kind of like excel would). Each value in the array is a custom object that contains an IsDirty dependency property. The IsDirty property gets set when the value is changed. When i run this: change a value in column 1 = whole row goes yellow change a value in any other column = nothing happens I want only the changed cell to go yellow no matter what column its in. Do you see anything wrong with my XAML?

• Split WPF Style XAML Files

  - by anon

  Most WPF styles I have seen are split up into one very long Theme.xaml file. I want to split mine up for readability so my Theme.xaml looks like this: <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="/PresentationFramework.Aero;v3.0.0.0;31bf3856ad364e35;component/themes/aero.normalcolor.xaml"/> <ResourceDictionary Source="Controls/Brushes.xaml"/> <ResourceDictionary Source="Controls/Buttons.xaml"/> ... </ResourceDictionary.MergedDictionaries> </ResourceDictionary> The problem is that this solution does not work. I have a default button style which is BasedOn the default Aero style for a button: <Style x:Key="{x:Type Button}" TargetType="{x:Type Button}" BasedOn="{StaticResource {x:Type Button}}"> <Setter Property="FontSize" Value="14"/> ... </Style> If I place all of this in one file it works but as soon as I split it up I get StackOverflow exceptions because it thinks it is BasedOn itself. Is there a way around this? How does WPF add resources when merging resource dictionaries?

• CSS: Style applied to a combination of classes?

  - by Eli

  Hi All, I'm not sure this is possible, but is there a syntax to be used in CSS when you want to style an element based on the combination of classes applied to it? I understand that I can check an element with jQuery or something and change it's style based on the classes it has, but is there a pure CSS way to do this? For example, if I have a class for bold and green: .bold_green { color:green; font-weight:bold; } And a class for bold and blue: .bold_blue { color:green; font-weight:bold. } Now, say I am using jQuery to add and remove classes dynamically and want any element that has both classes to turn italic pink. Something like: .bold_green AND .bold_blue { color:pink; font-style:italic; } Or, if I want to style an element that has aclass, and is a descendant of another element that has another class? Something like: .bold_green HAS_CHILD .bold_blue { color:black; background-color:yellow; } Thanks!

• Setting style on first and last visible TabItem of TabControl

  - by Donnelle

  I want to set a style on the first and last TabItems in a TabControl, and have them updated as the visibility of the TabItems is changed. I can't see a way to do so with triggers. What we're after looks like this: | | And the visibility of TabItems are determined by binding. I do have it working in code. On TabItem visibility changed, enumerate through TabItems until you find the first visible one. Set the style on that one. For all other visible TabItems, set them to the pointy style (so that the previously first visible one is now pointy). Then start from the end until you find a visible TabItem and set the last style on that one. (This also lets us address an issue with TabControl where it will display the content of a non-visible TabItem if none of the visible TabItems are selected.) There's undoubtably improvements I could make to my method, but I'm not convinced that it IS the right approach. How would you approach this?

• UI Automation Button Style Enabled

  - by Victor Gaspar

  Hi, I'm evaluating UI Automation for UI testing for that I have a WPF application with the following button defined: <Button Style="{DynamicResource ButtonStyle}" x:Name="MyBtn"/> when I need to visually disable the button I just change the style so the user is aware that the button is disabled (the colour changed) but still the button is internally enabled so I can still launch the OnClick event in order to show a message when the user clicks on a "disabled" button. Now the problem is that I don't know how to check from UI Automation the Style that its currently applied i.e. if the button is disabled or enabled. Do you know how can I do that? In a normal situation I should do something like that: Automation.Condition cEBtn = new PropertyCondition(AutomationElement.AutomationIdProperty, "MyBtn"); AutomationElement mybtnElement = appRegraceElement.FindFirst(TreeScope.Children, cEBtn); bool disMyBtn = (bool)mybtnElement .GetCurrentPropertyValue(AutomationElement.IsEnabledProperty); but in my case the button is always enabled therefore I need to check the Style applied to the button. Thank you very much. Best regards

• Apply CSS style to anchor problem

  - by Jake

  Using jquery I have a clicking tab mechanism that are nothing but anchor tags that return false but call javascript functions to run some events on the page. The problem is I am using jquery to apply an opacity style to the active anchor. and the other sibling anchor get a lesser opacity view. My code looks like this $("#menutab li a").click(function(){ $(this).animate({opacity:'1'},1000); $(this).siblings().animate({opacity:'.25'},1000); } I would think this code would act only on the clicked element and apply that css style to that element and the other style to the other anchor tags except the clicked one. It kind of does that, but also what it does is leave the earlier clicked element to opacity =1, so if I click an element it sets it opacity to 1 and then if I click another one it sets it opacity to 1 while leave the earlier clicked one to 1 also instead of setting it to .25 like the others. Edit: I changed the above code to: $("#menutab ul li").click(function(){ $(this).children().animate({opacity:'1'},1000); $(this).siblings().children().animate({opacity:'.25'},1000); }); and now I get the desired effect, except that when the first anchor in the list is clicked doesn't follow the event rules, When the first one is clicked its as if, the click event is not triggered, because no opacity style changes. which I don't understand.

• WPF Buttons Style

  - by Polaris

  I have WPF Form which has many buttons with the same code. Appearance of all buttons must be the same For example, code for one of these buttons <Button x:Name="btnAddRelative" Width="120" Click="btnAddRelative_Click" > <Button.Content> <StackPanel Orientation="Horizontal"> <Image Height="26" HorizontalAlignment="Left"> <Image.Source> <BitmapImage UriSource="images/add.png" /> </Image.Source> </Image> <TextBlock Text=" Add Relative" Height="20" VerticalAlignment="Center"/> </StackPanel> </Button.Content> </Button> How can I create one style and use it for all my buttons. All buttons has the same png image, only their text different. How can I do this. I tried to do this with Style object in Resource Section: <UserControl.Resources> <Style TargetType="Button" x:Key="AddStyle"> <Setter Property="Content"> <Setter.Value> <StackPanel Orientation="Horizontal"> <Image Height="26" HorizontalAlignment="Left"> <Image.Source> <BitmapImage UriSource="images/add.png" /> </Image.Source> </Image> <TextBlock Text=" " Height="20" VerticalAlignment="Center"/> </StackPanel> </Setter.Value> </Setter> </Style> </UserControl.Resources> But this code not work. Can any body know how can I do this?

• how to set style through javascript in IE immediately

  - by rezna

  Hi, recently I've encountered a problem with IE. I have a function function() { ShowProgress(); DoSomeWork(); HideProgress(); } where ShowProgress and HideProgress just manipulate the 'display' CSS style using jQuery's css() method. In FF everything is OK, and at the same time I change the display property to block, progress-bar appears. But not in IE. In IE the style is applied, once I leave the function. Which means it's never shown, because at the end of the function I simply hide it. (if I remove the HideProgress line, the progress-bar appears right after finishing executing the function (more precisely, immediately when the calling functions ends - and so there's nothing else going on in IE)). Has anybody encountered this behavior? Is there a way to get IE to apply the style immediately? I've prepared a solution but it would take me some time to implement it. My DoSomeWork() method is doing some AJAX calls, and these are right now synchronous. I assume that making them asynchronous will kind of solve the problem, but I have to redesign the code a bit, so finding a solution just for applying the style immediately would much simplier. Thanks rezna

• Span with white-space style in IE (7) applied _past_ end of span

  - by WaldenL

  We've got an application where users can enter "notes" into a rich edit control (Telerik's RedEditor, but that doesn't matter here). We had a user enter notes from w/in Safari that had a <span></span> in the middle of the note, and that span had a style on it specifying white-space:pre The HTML of the note was in the form of: <div> This is a note <span class="Apple-tab-span" style="white-space: pre; "> </span> and here's more of the note. </div> Simple enough, the style should apply to the span, and the span had 4 spaces in it. There should have been 4 spaces in the resulting output. Here's the problem. IE seems to apply that white-space: pre; style not only to the span, but to the enclosing div! Therefore, this long line that should have wrapped since it's not in the span, now pushed the document out until the line fits on the page. What am I missing. I know IE has problems, but this doesn't seem right, even for IE. So, the question(s): 1) Am I correct that the white-space attribute should only have applied to the span? 2) Can this be resolved somehow? Remember, I'm not in control of the content being entered. And it's entered from a mac w/Safari and being viewed in IE. Edit: The doctype on the page in question is: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

• Change style of text field based on the selection of a combo box using Javascript

  - by baldwingrand

  I would like to change the style of a text field based on the value selected in a combo box. Specifically, what I'd like to do is make the txtDepartment field gray and marked as "read only" if the option value selected in cboSource is 1. I've tried the code below, but I imagine my style code at least is wrong, if not other things. Any help appreciated. Thanks! <select name="cboSource" id="cboSource" onClick="displayDepartment(this);"> <option value = 1>Source 1</option> <option value = 2>Source 2</option> </select> <input name="txtDepartment" type="text" id="txtDepartment" size="6" maxlength="6"></p> <script> function displayDepartment(obj) { var selectedValue = obj.value; var txtDepartment = document.getElementById("txtDepartment"); if (selectedValue == "1") { txtDepartment.style.display = "Disabled style='background-color:#E8E8E8'"; } } </script>
