I&#39;m using Mercurial. I made a clone of a repository. For debugging, I changed a few lines of code in a java file. I did not commit those changes though. I just want to revert them back to their original state, as found in the repository. I tried `hg revert filename.java`, which did revert it, but now when I do `hg status`, I see additional files added in my folder now like:

    ? filename.java.orig

Can I just delete those files, and why does Mercurial make them when I use revert?

Is it possible to force the user to upgrade once there is a new version of my application available in the iTunes Store?

I am presently working on an application. However, I want to force the upgrade whenever I upload a newer version, because the upgrade will have more features and I want to discard the previous version. Is this possible by default with iPhone or do I have to write my own implementation to check the current version and compare it to the store?

Can I force an iPhone user to upgrade an application?

I found that it is possible to set dimensions of my interface elements in XML layouts using DIPs as in following fragment: 

    android:layout_width=&quot;10dip&quot;

But all Java interface takes integer as arguments and there is no way to specify dimensions in DIPs. What is the correct way to calculate this?

I figured that I have to use property density of `DisplayMetrics` class but is this a correct way? 

May I rely on this formula being always correct?

&gt;pixels * DisplayMetrics.density = dip 

Is there a utility function for the conversion somewhere in Android?

Is it possible ?

I&#39;m having a problem trying to run an Android app which, up until adding a second external library to its build path, was working fine. Since having added the scoreninja jar, I now get a **NoClassDefFoundError** when I try to run the app.

Here&#39;s the message:

    02-11 21:45:26.154: ERROR/AndroidRuntime(3654): java.lang.NoClassDefFoundError: com.scoreninja.adapter.ScoreNinjaAdapter

As all of the build scripts are generated by the Android tools (?), I&#39;m not sure what else I can do other than cleaning and rebuilding or restarting eclipse (I have already tried all three). Does anyone know how I can amend this?

Some times whenever I restart the application, which is built on 
Java
Struts
Mysql and Jboss 4.05 Version
I get the error as **Address already in use: JVM_Bind**

Only fix that i know is to restart the machine and try again, it will work.
Else Some times I do Ctrl-Alt-Del and Stop all the process related to Java, some times this also works.

But what is the exact reason and how can we prevent this problem ?

I came to know about null check using $null in velocity 1.6 through a resource updated by you.
Resource: https://stackoverflow.com/questions/24495/reading-model-objects-mapped-in-velocity-templates
But I am facing so many challenges that there is no $null for null check in velocity as there is no documentation provided about this.
Please provide me with documentation stating $null as valid for null check in velocity.

Thanks in Advance

Having real trouble using my localhost to test sites. It runs extremely slowly! Sometimes it takes up to a minute to load a page. I&#39;m using Firefox and the sites I&#39;m testing run fine on other developers in my office&#39;s local machines / on the production server.

I&#39;ve gone through the normal things :-

1. Disabled IPv6
2. Not running in debug mode
3. Put the site in the highest app pool (High Isolated) on IIS 6.
4. Taking of firewalls etc.

The problem only seems to occur when hitting pages which contain some form of .net code in the code-behind.

Appreciate that this a little bit of a vague topic / stab in the dark but would appreciate any sort of advice - it&#39;s horrible waiting a minute each refresh to try out a change!

Cheers, Sean.

I use Windows (7) OS as a development platform, running on a Mac / Parallels Desktop 5.


I would like to access the Windows localhost  - from the Mac side for testing purposes.

I&#39;ve found many solutions of accessing the other way around (access Mac&#39;s localhost from Windows) - but found no solution for this access direction (if any).

Any idea ? Is it possible ?

I want to have a check in my javascript if the page loading up is on my local machine.

The reason why I want to do that is that when I developing I like to make sure that both my server side(C#) validation is working correctly. So I like to see both the client side and server sides errors to show up.


So while I am testing I have a flag in my jquery validate stuff that just always lets invalid data go through. This way I see the client side and server errors at one go.

However right now I have to manually go and change back and forth when going from development to production.
