  • Doesn’t <asp:A runat=”server” B=”someValue” … /> syntax violate one of the basic rules in C# languag

    - by AspOnMyNet
    Assuming server control of type A has a protected member M, then we are also able to access A.M via declaring control tag A on some aspx page: <asp:A runat=”server” M=”someValue” … /> But isn’t one of the rules in C# that protected members of class A can only be accessed from A and from classes derived from A? So doesn’t the ability to access member A.M via <asp:A M=”someValue” … /> syntax violate this rule, since we are basically accessing A.M from a class ( which is automatically generated aspx class ) not derived from A?!

  • SharePoint Cannot Log in after making entry in hosts file

    - by bmw0128
    I'm building a MOSS 2007 site on Windows 2008 R2, 64 bit. Not wanting to use my machine name or IP in the URL, I made an entry in my hosts file: 127.0.0.1 mydev.com I can surf to the URL, http://mydev.com, but when I try to log in (Windows Authentication), I am denied. I am able to successfully log in if I take out the hosts file entry, and surf to http:// Do I need to edit something else for the authentication to work when I want to use a custom URL like mydev.com that is only mapped in the hosts file?

  • How do I get hyphens in my attribute names in Flex?

    - by John Leonard
    Flex has an issue with hyphens in xml. I need to generate an xml object with hyphens in the attribute for a Google Checkout implementation. I can get away with: var xml:XML = <item-description/>; and var xml:XML = <item-description the-name="foo"/>; but what I need to do is set the value of an attribute like this: var timestamp:String = methodToGetMyTimestampString(); var xml:XML = <item-desc/>; xml@start-date = timestamp; but I can't do that. Since flex doesn't like the hyphens, I don't know how to get or set attributes with hyphens in the name.

  • How to Add a File from my source tree to Maven Site

    - by Charles O.
    I have a Maven 2 RESTful application using Jersey/JAXB. I generate the JAXB beans from a schema file, where the schema file is in my resources directory, e.g., src/main/resources/foo.xsd. I want to include foo.xsd file in the generated Maven site for my project, so that clients can see the XML schema when writing RESTful calls. How can I include foo.xsd in the site? I could have a copy of the file in src/main/site/..., and then update my site.xml to point to it (or have a .apt whose contents point to it), but I don't like that because I'm still tweaking foo.xsd, and don't want to have to remember to copy it each time I update it. And that's just bad practice. I also tried having a .apt file that has a link to the foo.xsd which gets copied to the target/classes directory. That works until I do a site:deploy, because that only copies the target/site directory. Thanks, Charles

  • PHP, ANT and virtualhosts

    - by dbasch
    Hi all, I use the following standard folder structure with my projects: workspace myproject conf development.properties production.properties src build.xml build.properties build myproject Unfortunately, working with scripted languages nullifies the concept of separating the "workspace" from the "build". In my development environment, I use a virtual-host for each project. The virtual-host for a project is configured during the "deploytodevelopment" ANT task. Which method would you recommend for integrating PHP into my build process? Change the virtual-hosts setup to point to the workspace/myproject/src folder. Edit the PHP in the workspace/myproject/src folder. or Check out another working copy of the myproject/src folder to the build/myproject folder. Change the virtual-hosts setup to point to the build/myproject folder. Edit the PHP in the build/myproject folder.

  • Slow Browsing/Direct Download, but Fast Bittorrent Download

    - by Dr Haisook
    I'm using Windows XP SP2. I have a 1 MB connection via a SpeedTouch 585, and my internet speed registers at 0.3 MB, with a maximum download of 30kbps. Not to mention a terrible ping at 500-1500. On the other hand, I get full speed in uTorrent - a bittorrent program - reaching up to 100 kbps; the way it should be. I haven't made any changes to anything. And it has been functioning well until the last month. I waited in hope that it could be an ISP issue and that it would be resolved, but their support crew did not help me with this problem either. I've tried disabling all firewalls, and all wireless connections, using different browsers, and disabling QoS. But it did not work. Me thinks it's an ISP issue, but if so, how am I getting full speed in uTorrent? Could somebody help me out with this? Thanks.

  • Cursors 1 Sets 0

    - by GrumpyOldDBA
    I had an interesting experience with a database I essentially know nothing about. On the server is a database which stores session state, Microsoft provide the code/database with their dot net, so I'm told. Anyway this database has sat happily on the production server for the past 4 years I guess, we've finally made the upgrade to SQL 2008 and the ASPState database has also been upgraded. It seems most likely that the performance increase of our upgrade tipped the usage of this database into...(read more)

  • Performance logging tips

    - by Germstorm
    I am developing large data collecting ASP.Net/Windows service application-pair that uses Microsoft SQL Server 2005 through LINQ2Sql. Performance is always the issue. Currently the application is divided into multiple larger processing parts, each logging the duration of their work. This is not detailed and does not help us with anything. It would be nice to have some database tables that contain statistics that the application itself collected from its own behavior. What logging tips and data structures do you recommend to spot the parts that cause performance problems?

  • ASP.Net Session data lost between pages

    - by Ananth
    Hi, i came across a weird behavior today w/ my web application. When I navigate from a page to another, I lose one particular session variable data. I'm able to launch the app in firefox and able to see that the session data is not lost. I use Response.Redirect(page2, false) to redirect to another page. Below code was used to track session variables System.IO.StreamWriter sw = new System.IO.StreamWriter(@"c:\test.txt", true); for (int i = 0; i < Session.Count; i++) { sw.WriteLine(Session.Keys[i] + " " + Session.Contents[i]); } sw.Close(); Can anyone help me in this? Any help is appreciated. ~/Ananth

  • Is a switch statement the fastest way to implement operator interpretation in Java

    - by Mordan
    Is a switch statement the fastest way to implement operator interpretation in Java public boolean accept(final int op, int x, int val) { switch (op) { case OP_EQUAL: return x == val; case OP_BIGGER: return x > val; case OP_SMALLER: return x < val; default: return true; } } In this simple example, obviously yes. Now imagine you have 1000 operators. would it still be faster than a class hierarchy? Is there a threshold when a class hierarchy becomes more efficient in speed than a switch statement? (in memory obviously not) abstract class Op { abstract public boolean accept(int x, int val); } And then one class per operator.

  • Help with C puzzle

    - by Javier Badia
    I found a site with some complicated C puzzles. Right now I'm dealing with this: The following is a piece of C code, whose intention was to print a minus sign 20 times. But you can notice that, it doesn't work. #include <stdio.h> int main() { int i; int n = 20; for( i = 0; i < n; i-- ) printf("-"); return 0; } Well fixing the above code is straight-forward. To make the problem interesting, you have to fix the above code, by changing exactly one character. There are three known solutions. See if you can get all those three. I cannot figure out how to solve. I know that it can be fixed by changing -- to ++, but I can't figure out what single character to change to make it work.

  • How to close all tabs in Safari using AppleScript?

    - by Form
    I have made a very simple AppleScript to close all tabs in Safari. The problem is, it works, but not completely. Here's the code: tell application "Safari" repeat with aWindow in windows repeat with aTab in tabs of aWindow aTab close end repeat end repeat end tell I've also tried this script: tell application "Safari" repeat with i from 0 to the number of items in windows set aWindow to item i of windows repeat with j from 0 to the number of tabs in aWindow set aTab to item j of tabs of aWindow aTab close end repeat end repeat end tell ... but it does not work either. I tried that on my system (MacBook Pro jan 2008), as well as on a Mac Pro G5 under Tiger and the script fails on both, albeit with a much less descriptive error on Tiger. The problem is that only a couple of tabs are closed. Running the script a few times closes a few tab each time until none is left, but always fails with the same error after closing a few tabs. Under Leopard I get an out of bounds error. Since I am using fast enumeration (not using "repeat from 0 to number of items in windows") I don't see how I can get an out of bounds error with this... My goal is to use the Cocoa Scripting Bridge to close tabs in Safari from my Objective-C Cocoa application but the Scripting Bridge fails in the same manner. The non-deletable tabs show as NULL in the Xcode debugger, while the other tabs are valid objects from which I can get values back (such as their title). In fact I tried with the Scripting Bridge first then told myself why not try this directly in AppleScript and I was surprised to see the same results. I must have a glaring omission or something in there... (seems like a bug in Safari AppleScript support to me... :S) I've used repeat loops and Obj-C 2.0 fast enumeration to iterate through collections before with zero problems, so I really don't see what's wrong here. Anyone can help? Thanks in advance!

  • getSharedPreferences not working for me with concerns to ListPreferences and Integers

    - by ideagent
    I'm stuck at a point where I'm trying to get my project to read a preference value (from a ListPreference listing) and then use that value in a basic mathematical subtraction instance. The problem is that the "seek" preference is not being seen by my Java code, and yet the default value is (I've tried the default value with 3000 and now 0). Am i missing something, is there a bug here, known or unknown? Java code chunk where the issues manifests itself: public static final String PREF_FILE_NAME = "preferences"; seekback.setOnClickListener(new Button.OnClickListener() { @Override public void onClick(View view) { try { SharedPreferences preferences = getSharedPreferences(PREF_FILE_NAME, MODE_PRIVATE); Integer storedPreference = preferences.getInt("seek", 0); (mediaPlayer.getCurrentPosition()-storedPreference); } catch (Exception e) { e.printStackTrace(); } } }); Here are some other code bits for my project: From preferences file: <ListPreference android:entries="@array/seconds" android:entryValues="@array/seconds_values" android:summary="sets the seek interval for the seekback and seekforward buttons" android:title="Seek Interval" android:defaultValue="5000" android:key="@string/seek" From strings file: seek From an array file: Five seconds Fifteen seconds Thirty seconds Sixty seconds 5000 15000 30000 60000 let me know if you need to see more code to figure this one out Thanks in advance for any help that can be offered. I've worked over this issue now for a few hours and I'm burnt, a second pair of eyes on it would be very much appreciated. Arg, not sure how to get the code and plain text to format nicely here, even tried the options, like Code Sample, no luck AndroidCoder

  • How can I make this SQL query more efficient? PHP.

    - by Alan Grant
    Hi all, I have a system whereby a user can view categories that they've subscribed to individually, and also those that are available in the region they belong in by default. So, the tables are as follows: Categories UsersCategories RegionsCategories I'm querying the db for all the categories within their region, and also all the individual categories that they've subscribed to. My query is as follows: Select * FROM (categories c) LEFT JOIN users_categories uc on uc.category_id = c.id LEFT JOIN regions_categories rc on rc.category_id = c.id WHERE (rc.region_id = ? OR uc.user_id = ?) At least I believe that's the query, I'm creating it using Cake's ORM layer, so the exact one is: $conditions = array( array( "OR" => array ( 'RegionsCategories.region_id' => $region_id, 'UsersCategories.user_id' => $user_id ) )); $this->find('all', $conditions); This turns out to be incredibly slow (sometimes around 20 seconds or so. Each table has around 5,000 rows). Is my design at fault here? How can I retrieve both the users' individual categories and those within their region all in one query without it taking ages? Thanks!

  • Mercurial to Mercurial to Subversion Workflow Problem

    - by Dalroth
    We're migrating from Subversion to Mercurial. To facilitate the migration, we're creating an intermediate Mercurial repository that is a clone of our Subversion repository. All developers will be begin switching over to the Mercurial repository, and we'll periodically push changes from the intermediate Mercurial repository to the existing Subversion repository. After a period of time, we'll simply obsolete the Subversion repository and the intermediate Mercurial repository will become the new system of record. Dev 1 Local --+--> Mercurial --+--> Subversion Dev 2 Local --+ + Dev 3 Local --+ + Dev 4 -------------------------+ I've been testing this out, but I keep running into a problem when I push changes from my local repository, to the intermediate Mercurial repository, and then up into our Subversion repository. On my local machine, I have a changeset that is committed and ready to be pushed to our intermediate Mercurial repository. Here you can see it is revision #2263 with hash 625... I push only this changeset to the remote repository. So far, everything looks good. The changeset has been pushed. hg update 1 files updated, 0 files merged, 0 files removed, 0 files unresolved I now switch over to the remote repository, and update the working directory. hg push pushing to svn://... searching for changes [r3834] bmurphy: database namespace pulled 1 revisions saving bundle to /srv/hg/repository/.hg/strip-backup/62539f8df3b2-temp adding branch adding changesets adding manifests adding file changes added 1 changesets with 1 changes to 1 files rebase completed Next, I push the change up to Subversion, works great. At this point, the change is in the Subversion repository and I return attention back to my local client. I pull changes to my local machine. Huh? I've now got two changesets. My original changeset appears as a local branch now. The other changeset has a new revision number 2264, and a new hash 10c1... Anyway, I update my local repo to the new revision. I'm now switched over. So, I finally click the "determine and mark outgoing changesets" and as you can see Mercurial still wants to push out my previous changesets even though they've already been pushed. Clearly, I'm doing something wrong. I also can't merge the two revisions. If I merge the two revisions on my local machine, I end up with a "merge" commit. When I push that merge commit out to the intermediate Mercurial repository, I can no longer push changes out to our Subversion repository. I end up with the following problem: hg update 0 files updated, 0 files merged, 0 files removed, 0 files unresolved hg push pushing to svn://... searching for changes abort: Sorry, can't find svn parent of a merge revision. and I have to rollback the merge to get back to a working state. What am I missing?

  • Friendly_id for fixtures (slugs)

    - by Obaid
    I am using freindly_id in my application. I have setup a few fixtures in my application. I want to do integration testing on them. During the tests I need the friendly_id, but the DB records created from fixtures do not have the corresponding slugs in the Slug table. Aren't the slugs automatically created from Fixture data? If not then what can be a solution?
