  • System.Windows.Media.RenderCapability.Tier returns not the render mode

    - by happyclicker
    I use System.Windows.Media.RenderCapability.Tier to show the current render mode within a diagnostics panel of my app. If I force the app (3.5sp1) to change the render-mode through the following code HwndSource hwndSource = PresentationSource.FromVisual(visual) as System.Windows.Interop.HwndSource; HwndTarget hwndTarget = hwndSource.CompositionTarget; hwndTarget.RenderMode = renderMode; neither System.Windows.Media.RenderCapability.TierChanged fires, nor has the System.Windows.Media.RenderCapability.Tier property changed. However the changes are applied to the app. If I look with Perforator, the render mode has been changed to the desired mode. Although I’ve found at many locations that System.Windows.Media.RenderCapability.Tier can be used to detect the current render state (also msdn, see this), it seems, System.Windows.Media.RenderCapability only gives information about the capabilities and not about the current mode. That makes also sense if I look at the name of the class. Is there another source to know how an actual wpf-content is rendered or am I doing something wrong?

  • System beeps on shutdown

    - by Nicholas Smith
    Very recently a couple of our systems have started making beeps on shutdown, we've not been able to isolate the exact time that they've been updated and it's occuring, but I've narrowed it down to being not pcspkr or snd_pcsp as both are blacklisted under modprobe, and rmmod'ed just to be sure. Now I'm a bit puzzled as I was under the impression those were the only two modules that could make the beep, is there a third lurking that I need to blacklist? Edit: I've copied the results of lsmod over on Pastebin.

  • registration form with payment system ( paypal ) [closed]

    - by Alecs
    I'm using an ajax registration form plugin for my website and I'm thinking to implement also Paypal. Here is how I want to implement it : I have 3 labels ( Name, Phone, Email, ) and a " Buy " button. After the user is typing his name, phone and email they click on "Buy" and they will be redirected to the paypal payment page or if it's possible to stay on the same page. Probably, what I need to know is how to make the "Buy " only after the forms ( name, phone, email ) are validated. Is there a plugin, or a snippet of code already made to not start something which already exists.

  • Implementation of recurring fee system

    - by TPSstar
    I'm developing an application which will list members who have not paid their any previous month's fee and a separate list for those who have paid the fee. So, lets say a member who will be paying fee through out the year, each month and if he didn't pay fee for march 2013 then app should highlight him as un-paid member. What would be best practice to achieve it. Adding fee invoices for whole year already in database when member is added then loop through his payments to check if fee is paid or not, or add a validation date for member on his each payment, for example payment made in Feb 2013 then member is valid till 28.02.2013. Check if date today is 28.02.2013 then he has not paid..

  • An object reference is required for the non-static field, method, or property using global variable

    - by Jose Cardama
    Hello Iam working in a global int in which a variable will be used later. I've made the global variable like this: class Foo { public static int stream = Bass.BASS_StreamCreateFile(path1.Text, 0, 0, BASSFlag.BASS_DEFAULT); } which will be later called like this: Foo.stream and it can also contain more then 1 stream for example stream20,30,etc... The problem here is that it returns me this error: "An object reference is required for the non-static field, method, or property" where I call the text in path1.Text How do I fix this?

  • Variable type for Application on Time Events [on hold]

    - by user2931226
    Been Trying to figure out how to go about setting a Variable for some Application On Time events, But still not confident to do it. These events (Macro's) get called by another Macro then they wait for 10 - 20 minutes, then they don't Run. So have read that (EarliestTime argument) should be assigned to a variable to store it other wise it looses it when other things are running Help appreciated Thanks Sub settimers() Application.OnTime TimeValue(Range("$X$9").Text), "StartBlink" Application.OnTime TimeValue(Range("$W$11").Text), "StopBlink" End Sub

  • Do you use a grid system when designing a web page?

    - by johnny
    I'm trying to figure out why I would use a grid system. I have read some but I just don't get it. I'm used to just putting stuff in html on a page and beind done with it but I have a new project and would like to use a grid because apparently it is a best practice. I read in one article referenced in another SO question and it said that grid design was in all sorts of development, even application form design. That made me think of things like snap to grid, etc. and I didn't know if the grid in the web design sphere was the same. I was hoping someone could give me a brief but not overly complicated view and not a link to Google which I have used already. Thank you for any help.

  • PHP: Set variable in to include file in 'if' statement

    - by swiftsly
    I am trying to set a variable in an 'if' statement so that only when the 'if' statement is true, the variable will be set and will be able to be used somewhere else on the page. Here's what I have tried: if ($row[8] == 1) { echo 'Message here'; ob_start(); include('F164.php'); $f164 = ob_get_clean(); } as well as: if ($row[8] == 1) { echo 'Message here'; $f164 = include('F164.php'); }

  • Particle system lifetimes in OpenGL ES 2

    - by user16547
    I don't know how to work with my particle's lifetimes. My design is simple: each particle has a position, a speed and a lifetime. At each frame, each particle should update its position like this: position.y = position.y + INCREMENT * speed.y However, I'm having difficulties in choosing my INCREMENT. If I set it to some sort of FRAME_COUNT, it looks fine until FRAME_COUNT has to be set back to 0. The effect will be that all particles start over at the same time, which I don't want to happen. I want my particles sort of live "independent" of each other. That's the reason I need a lifetime, but I don't know how to make use of it. I added a lifetime for each particle in the particle buffer, but I also need an individual increment that's updated on each frame, so that when PARTICLE_INCREMENT = PARTICLE_LIFETIME, each increment goes back to 0. How can I achieve something like that?

  • Environment variable expansion in persistence.xml (JPA)

    - by user342495
    I am developing a Eclipse RCP plugin which uses JPA. I tried to specify the database path via a variable give to the JVM on runtime. The property is set correctly but the database is created in a folder named after the variable name (here: ${DBHOME}). <property name="javax.persistence.jdbc.url" value="jdbc:derby:${DBHOME};create=true"/> Is there a possibility to fix this? Thx

  • Quetion regarding local and global variable in javascript

    - by caramel1991
    Today,I started to code a page that prompt the user to choose their PC spec,and the code is as follow <html> <title>Computer Specification Chooser</title> <head> <script type="text/javascript"> var compSpec = document.compChooser; function processorUnavailable_onclick() { alert("Sorry that processor speed is currently unavailable"); compSpec.processor[2].checked = true; } </script> </head> <body> <form name="compChooser"> <p>Tick all components you wan included on your computer</p> <p> DVD-ROM <input type="checkbox" name="chkDVD" value="DVD-ROM" /> <br /> CD-ROM <input type="checkbox" name="chkCD" value="CD-ROM" /> <br /> Zip Drive <input type="checkbox" name="chkZIP" value="ZIP DRIVE" /> </p> <p> Select the processor speed you require <br /> <input type="radio" name="processor" value="3.8" /> 3.8 GHZ <input type="radio" name="processor" value="4.8" onclick="processorUnavailable_onclick()" /> 4.8 GHZ <input type="radio" name="processor" value="6" /> 6 GHZ </p> <input type="button" name="btnCheck" value="Check Form" /> </form> </body> </html> The problem I'm facing is on the function that I've tie to the event handler,when I try to choose the radio button of the processor value 4.8 GHZ,yes it alert me with the message inside the function,but after that,it doest not execute the next statement inside the function,that is to check the next processor value 6 GHZ,I've try my effort to change it and test on it,and find out when I set the var compSpec = document.compChooser as a local variable inside the function instead of a global variable,the next statement could be executed.But I thought for a global variable,it is accessible in everywhere on the page and also inside a function.But why now I can't accesses it inside my function??Any idea??Besides,I stumble upon a weird article while googling,it says that when a global variable is created,it is added to window object.I just curious why this happen??And what's the benefits and uses of it??THANK YOU

  • System.Data.Sqlclient.Sqlexception: Line1 incorrect syntax ...

    - by marocanu2001
    Given a SqlConnection, a SqlCommand if you need to execute a stored procedure it is enough to specify the stored procedure name as the CommandText and it will work. Now the surprise is that if you also add parametres, you get this creepy error: SqlException: Line 1 incorrect syntax near [storedProcedureName]. The quick fix is to specify the CommandType to be StoredProcedure.

  • Pointers to implementing a taxonomy system?

    - by petsagouris
    I am taking part in the development of a PHP CMS (yeah I know you are like, meeh). It is currently using simple tags for tagging content. What I want to do is push the whole thing to using Taxonomy but I am not sure on what to pay attention to, or how to go about structuring the whole vocabularies/terms. I'd love to be able to keep the user interaction close to that of the current simple tags and at the same time allow for more advanced usage by power users. The Drupal and the Wordpress taxonomy systems are being reviewed at the moment and they provide valuable resources. Nevertheless, it could be that someone has some simpler and more appropriate thoughts on this matter.

  • How to add ONLY system tray icon to application?

    - by badpanda
    I am developing an application that will be running behind the scenes in Windows and would like to put an icon in the system tray for troubleshooting purposes (simple way for users to tell if the app is running). There is no other UI for the application, and the icon does not need to have any functionality as of right now. All of the solutions I have found as of yet involve creating a form. I am wondering if there is a way to simply add a class to my current C# code that allows me to control the icon, rather than doing the whole 'make a form, set it to be invisible....' nonsense that seems to be the popular suggestion on the forums. Something along the lines of the way that UI control is done in say, Swing for Java. I would really appreciate any ideas! (Sorry if this is a n00b question...I haven't used C# before...) Thanks! badPanda

  • How to make my proxy settings change depending on the network I connect to?

    - by Little Jawa
    My company's corporate network requires me to set a network proxy to access the net, but when I am anywhere else, I don't need it. The proxy settings in Ubuntu (System - Preferences - Proxy server) allowed me to create "locations" that I can manually select. Then I have a "default" location (with no proxy) and a "work" location (with my company's proxy in it). Is there a way to make Ubuntu automatically select the "work" location based on the connection I'm using? I thought I could use the IP subnet (very specific) to detect where I am, but I have no idea how to set it up... Edit: I really need to have the proxy settings set at the system level. All my network connections (IMAP, SMTP, chat, etc) need to go through the proxy. Not only the web browser.

  • Why not System.Void?

    - by Stewart
    I have no practical reason for knowing this answer, but I'm curious anyway... In C#, trying to use System.Void will produce a compilation error: error CS0673: System.Void cannot be used from C# -- use typeof(void) to get the void type object As I understood it, void is simply an alias of System.Void. So, I don't understand why 'System.Void' can't be used directly as you might with 'string' for 'System.String' for example. I would love to read an explanation for this! Incidentally, System.Void can be successfully used with the Mono compiler, instead of Microsoft's .Net, and there it appears equivalent to using the void keyword. This must therefore be a compiler-enforced restriction rather than a CLR restriction, right?

  • Do there exist programming languages where a variable can truly know its own name?

    - by Job
    In PHP and Python one can iterate over the local variables and, if there is only once choice where the value matches, you could say that you know what the variable's name is, but this does not always work. Machine code does not have variable names. C compiles to assembly and does not have any native reflection capabilities, so it would not know it's name. (Edit: per Anton's answer the pre-processor can know the variable's name). Do there exist programming languages where a variable would know it's name? It gets tricky if you do something like b = a and b does not become a copy of a but a reference to the same place. EDIT: Why in the world would you want this? I can think of one example: error checking that can survive automatic refactoring. Consider this C# snippet: private void CheckEnumStr(string paramName, string paramValue) { if (paramName != "pony" && paramName != "horse") { string exceptionMessage = String.Format( "Unexpected value '{0}' of the parameter named '{1}'.", paramValue, paramName); throw new ArgumentException(exceptionMessage); } } ... CheckEnumStr("a", a); // Var 'a' does not know its name - this will not survive naive auto-refactoring There are other libraries provided by Microsoft and others that allow to check for errors (sorry the names have escaped me). I have seen one library which with the help of closures/lambdas can accomplish error checking that can survive refactoring, but it does not feel idiomatic. This would be one reason why I might want a language where a variable knows its name.
