  • How to disable ASP.NET MVC url routing

    - by Luke101
    Just would like to know how do I disable URL Rewriting in asp.net MVC. I don't need url rewriting in my application and would like to turn it off. Reason: I am aware that url rewriting uses reflection and would like to save a few cpu cycles by avoiding it. Thanks

  • Streaming data to the browser as a file of unknown size

    - by Sir Psycho
    I have some data which is queried from the database and I'd like to send it to the client as a csv file. The file size varies each time due to the fact that the DB data returned can be of any size. Instead of saving this file to the hard disk, I'd like to send it to the browser at the same time it's being processed into a CSV by my algorithm. Response.Write seems useless. For some reason, the file download dialog is only displayed once my processing is finished. This seems odd as I'm writting all my output to the Response.Output stream. I have downloaded files on the web before where the filesize is not known and the browser just keeps on downloading. Is there any way to achieve this? The following stackoverflow thread did not offer any good advise. http://stackoverflow.com/questions/873995/asp-net-downloading-large-files-of-unknown-size Thanks

  • Universal control - simple question about dock and anchor

    - by Vytas999
    I use Visual Studio .NET to develop internal applications. I create a Windows control that will display custom status bar information. Different developers will use the control to display the same information in many different applications. The control must always be displayed at the bottom of the parent form in every application. It must always be as wide as the form. When the form is resized, the control should be resized and repositioned accordingly. How should I do that in the best way and why? A)Create a property to allow the developers to set the Dock property of the control. Set the default value of the property to AnchorStyle.Bottom. B) Create a property to allow the developer to set the Anchor property of the control. Set the default value of the property to AnchorStyle.Bottom.

  • Add an array of buttons to a GridView in an Android application

    - by Tai Squared
    I have an application that will have 5-15 buttons depending on what is available from a backend. How do I define the proper GridView layout files to include an array of buttons that will each have different text and other attributes? Each button will essentially add an item to a cart, so the onClick code will be the same except for the item it adds to the cart. How can I define an array so I can add a variable number of buttons, but still reference each of them by a unique ID? I've seen examples of the arrays.xml, but they have created an array of strings that are pre-set. I need a way to create an object and not have the text defined in the layout or arrays xml file. Update - Added info about adding to a GridView I want to add this to a GridView, so calling the addView method results in an UnsupportedOperationException. I can do the following: ImageButton b2 = new ImageButton(getApplicationContext()); b2.setBackgroundResource(R.drawable.img_3); android.widget.LinearLayout container = (android.widget.LinearLayout) findViewById(R.id.lay); container.addView(b2); but that doesn't layout the buttons in a grid like I would like. Can this be done in a GridView?

  • Wrappers/law of demeter seems to be an anti-pattern...

    - by Robert Fraser
    I've been reading up on this "Law of Demeter" thing, and it (and pure "wrapper" classes in general) seem to generally be anti patterns. Consider an implementation class: class Foo { void doSomething() { /* whatever */ } } Now consider two different implementations of another class: class Bar1 { private static Foo _foo = new Foo(); public static Foo getFoo() { return _foo; } } class Bar2 { private static Foo _foo = new Foo(); public static void doSomething() { _foo.doSomething(); } } And the ways to call said methods: callingMethod() { Bar1.getFoo().doSomething(); // Version 1 Bar2.doSomething(); // Version 2 } At first blush, version 1 seems a bit simpler, and follows the "rule of Demeter", hide Foo's implementation, etc, etc. But this ties any changes in Foo to Bar. For example, if a parameter is added to doSomething, then we have: class Foo { void doSomething(int x) { /* whatever */ } } class Bar1 { private static Foo _foo = new Foo(); public static Foo getFoo() { return _foo; } } class Bar2 { private static Foo _foo = new Foo(); public static void doSomething(int x) { _foo.doSomething(x); } } callingMethod() { Bar1.getFoo().doSomething(5); // Version 1 Bar2.doSomething(5); // Version 2 } In both versions, Foo and callingMethod need to be changed, but in Version 2, Bar also needs to be changed. Can someone explain the advantage of having a wrapper/facade (with the exception of adapters or wrapping an external API or exposing an internal one).

  • Can I create a cross-project source reference in redmine?

    - by UlfR
    If you have two separate projects that is somehow connected. How can one make a reference to the source of the other project? For referencing the source of your own project you use: source:some/file But since I want to refer to code in another project my thought was that I could write something like: other_project:source:some/file Anyone that knows if this is possible in some way? I have read http://www.redmine.org/wiki/redmine/RedmineTextFormatting#Redmine-links but found no clues there.

  • JSF Page does not submit when onclick javascript is added to menu item?

    - by Padmarag
    I show some detail using popup windows. I want to close those when the user clicks on sign-out link. I have a JavaScript function that'll close the windows. The sign-out link is rendered using Navigation MenuModel. The definition in faces-config is as below - <managed-bean> <managed-bean-name>signoutNavigation</managed-bean-name> <managed-bean-class>com.xxx.xxx.framework.NavigationItem</managed-bean-class> <managed-bean-scope>none</managed-bean-scope> <managed-property> <property-name>label</property-name> <value>Sign Out</value> </managed-property> <managed-property> <property-name>viewId</property-name> <value>/signout.jsp</value> </managed-property> <managed-property> <property-name>outcome</property-name> <value>signout</value> </managed-property> <managed-property> <property-name>onclick</property-name> <value>closeOrderWindows()</value> </managed-property> </managed-bean> The problem is when I use the "onclick" property on managed-bean, the page doesn't submit to "signout.jsp" and remains on same page. When I remove/comment the "onclick" part, the page gets submitted properly. I use MyFaces Trinidad.

  • What regular expression do I need to check for some non-latin characters?

    - by zeckdude
    I am checking a field if it is Latin Characters or not. var foreignCharacters = $("#foreign_characters").val(); var rlatins = /[\u0000-\u007f]/; if (rlatins.test(foreignCharacters)) { alert("This is Latin Characters"); } else { alert("This is non-latin Characters"); } This works well, but I would like to change it so when I enter any non-latin characters, such as chinese characters, along with a space(which is within that range I am using currently) it will still say it is non-latin characters. How can I change the regular expression I have to do that?

  • VisualVM over ssh

    - by erwin
    I've read Visual VM remotely over ssh but I think I've not fully understood because it was not working for me :-( Please can someone give some example? ssh -D 9696 [email protected] and visualvm.exe -J-Dnetbeans.system_socks_proxy=localhost:9696 -J-Djava.net.useSystemProxies=true starts visualvm, but no processes of external machine are shown (only the local ones like visualvm itself). Moreover sometimes (but not always) I got the message "channel 3: open failed: connect failed: Connection refused" in my ssh window. Any help?

  • UPS recommendations for three grey boxes?

    - by Margaret
    Hey all We have a series of grey-box style computers acting as servers at my workplace (rather than rack-mount). We were looking to get Uninterruptible Power Supplies for them. However, I'm not sure how many at what capacity are required. I'd assume it would be a good idea to hook the peripherals in as well - there's a 18.5" LCD monitor with a KVM, along with a couple of USB hard drives that require power. I currently have the most vital machine hooked up to a cheap (temporary) UPS, but it's probably close to worse than nothing. I'm looking for reasonable value for money, though I can probably negotiate with my boss on price range. I recognise that I may well need to buy two (or even three) UPSs to support the three machines. Any recommendations?

  • Help me with the simplest program for "Trusted" application

    - by idazuwaika
    Hi, I hope anyone from the large community here can help me write the simplest "Trusted" program that I can expand from. I'm using Ubuntu Linux 9.04, with TPM emulator 0.60 from Mario Strasser (http://tpm-emulator.berlios.de/). I have installed the emulator and Trousers, and can successfully run programs from tpm-tools after running tpmd and tcsd daemons. I hope to start developing my application, but I have problems compiling the code below. #include <trousers/tss.h> #include <trousers/trousers.h> #include <stdio.h> TSS_HCONTEXT hContext; int main() { Tspi_Context_Create(&hContext); Tspi_Context_Close(hContext); return 0; } After trying to compile with g++ tpm.cpp -o tpmexe I receive errors undefined reference to 'Tspi_Context_Create' undefined reference to 'Tspi_Context_Close' What do I have to #include to successfully compile this? Is there anything that I miss? I'm familiar with C, but not exactly so with Linux/Unix programming environment. ps: I am a part time student in Master in Information Security programme. My involvement with programming has been largely for academic purposes.

  • Invoking cl.exe (MSVC compiler) in Cygwin shell

    - by barcarole
    I'm heavily using Cygwin (with Putty shell). But, it's quite tricky to invoke cl.exe (i.e., Visual C++ compiler toolchain) in the Cygwin bash shell. Running vcvars*.bat in the bash shell doesn't work obviously. I tried to migrate VC++'s environment variables to Cygwin, but it's not that easy. Is there anyone who ever tried to run VC++ compiler in Cygwin bash shell? Thanks, JJ

  • Is single float assignment an atomic operation on the iPhone?

    - by iter
    I assume that on a 32-bit device like the iPhone, assigning a short float is an atomic, thread-safe operation. I want to make sure it is. I have a C function that I want to call from an Objective-C thread, and I don't want to acquire a lock before calling it: void setFloatValue(float value) { globalFloat = value; }

  • Java portable media detection

    - by quosoo
    I would like to write a piece of java code that synchronizes files between local hard drive and a usb storage. I would like to have a different synchronization configuration depending on which usb storage is plugged in and I would like to have apropriate configuration to be selected automatically rather than chosen by the user. I've just read the JSR-80 and jUSB documentation as well as a bunch of articles and SO posts, but all of those are very old and it seems that since that time (around 2005) all the efforts have been abandoned especially for Windows platform, while the OS-independence is quite important to me (at least Windows and Linux need to be supported). Do I really need to use any of the USB APIs to recognize external drives that are connected to the system? I need something that is more unique than file path, drive letter or drive label... And if yes which one would you recommend (unless I missed something jUnit is actually the only for which Windows support exists).

  • TestDriven.net, right click, run test, doesn't re-build

    - by jeff
    I am using testDriven.net and when I right-click and run tests, it appears to build, then runs the test. Only it doesn't really do the build. I keep making changes and the test still fails:) I have to do a VS Build, then run the testDriven.net to get changes to take effect. This clears up for a while if I delete the solution's .SUO file. Any thoughts?
