How to make a bootable usb disk for windows?

2011-11-28T18:26:00.002+05:30

This is the best solution I could find in the net for making a DOS bootable disk. Thanks VistaX64!

http://www.vistax64.com/tutorials/191416-dos-usb-boot-drive.htmlhttp://www.vistax64.com/tutorials/191416-dos-usb-boot-drive.html

Once you are done with the steps, don't get upset if you see no files in the USB. It happens to me in my Windows XP but still the disk has the required files to boot. You can copy any additional files you need into the disk and use them once it is booted.

2011-06-03T13:33:00.002+05:30

If you are getting just one or two errors in your css, check the path of those resources.

Are you getting hundreds of such errors in your css, for all the resources? Then your css might be good ;-) Just comment out the css file in your source and take a look, you might have some broken embed resource path in your code (mxml or as). Fix it, you will be good.

Unable to load WSDL. If currently online, please verify the URI and/or format of the WSDL

2009-07-24T15:56:00.002+05:30

Check whether the URL is accessible from your browser.

If yes, make sure that you have a proper crossdomain.xml in the server (where the web-service is hosted) and accessible by the URL http://your_server/crossdomain.xml.
Eg:
<cross-domain-policy>
    <site-control permitted-cross-domain-policies="master-only"/>
    <allow-access-from domain="*" to-ports="*"/>
    <allow-http-request-headers-from domain="*" headers="SOAPAction"/>

[For details: http://www.adobe.com/devnet/articles/crossdomain_policy_file_spec.html]

PHP: try catch not working/exception is not catched

2009-06-02T13:27:00.000+05:30

If the catch block in your code is not executed and you are getting error/warning message in the browser, it is an issue with the behavior of PHP. In php some errors/warnings are not exceptions.

You could convert all errors to exceptions by using the following in your code.

set_error_handler(create_function('$p1, $p2, $p3, $p4', 'throw new ErrorException($p2, 0, $p1, $p3, $p4);'), E_ALL);

PHP: odbc_longreadlen() corruption problem

SQL error: [Microsoft][ODBC SQL Server Driver][SQL Server]The FOR XML clause is not allowed in a CURSOR statement

2009-05-29T16:09:00.002+05:30

If your sql query is something like
$sqlQuery = “select * from test for xml raw('MyItem'), elements, root('MyRoot')”;

As a work around you can wrap it inside another select statement.
$sqlQuery = "select (" . $sqlQuery . ")";

This query will return the record set containing only one row and one column and which will be your xml. You can get the xml by using odbc_result($queryResult,1);

If the xml is too big you may need to configure max_execution_time, memory_limit and odbc.defaultlrl in the php.ini file according to your requirement.

Do new mobiles still need to be charged for 8 hours?

2009-04-03T12:21:00.002+05:30

When I googled for this question, there were a lot of questions regarding this. The initial charging was required for the NiMH and NiCd batters but I believe that it is not required for the li-ion batters that we are using in our mobiles now a days.

The battery care section in the Nokia Europe site is not asking us to do an initial charging. Also the charging care section and the FAQ are not mentioning anything regarding an initial charging. Batteryuniversity.com is also not recommending an initial charging of 8 hours or 12 hours. So I suggest you to charge it until the phone show 'Battery Full'.

How to install JBoss?

2009-04-02T12:19:00.000+05:30

Download jemsinstaller (jar file) and make sure that you have JDK in your machine. You can start installation by double clicking the jemsinstaller jar file or by giving the command 'java -jar ’ in your command-line. You can download JBoss in many different formats too but this is the easiest one to install if you are a beginner and you have a GUI in your machine. You can also install this jar file using the command-line ($ java -jar jems-installer-1.2.0.jar installscript.xml). Here you can specify the configuration options in the installerscript.xml. The GUI based installation will allow you to generate the installation script automatically in the installation completed panel. For a beginner I recommend to use the GUI based installation of JBoss once and then go for the more advanced command-line installation of JBoss. Once the installation is complete you try http://localhost:8080/ if you can see the test page, you are done with it.

Review - Nokia 5130 XpressMusic

2009-03-30T15:02:00.004+05:30

I was very much confused when I bought this phone because of the comments and that is why I decided to give a review in my Blog. I am giving this review from my hands-own experience. This review is considering the price too.

Price: Rs.5949 ($119)

Look : 7/10
Sound (Speakers) : 8/10
Sound (Headset) : 6/10
Display : 8.5/10
Camera : 7/10
Restart problems in the last 3 days : 0
Hanging in the last 3 days : 0
Performance : 7/10
Features : 7.5/10
Games : 5/10
Themes : 5.5/10
Battery life : 7.5/10

My rating : 7/10

There are phones which will give you better experience, but there is no other phones available in India with in this price range (Considering Nokia, Samsung and Sony Ericsson).

If you are looking for a basic multimedia phone with camera and other reasonable features, then this is the right phone for you.

As far as I understood, the ref is like in/out and out is just out. What I meant is that you can send a value in to a function using a ref parameter but you can't send a value using an out parameter. Out parameter can be used only for returning a value from a function. Also the ref parameters should be initialized before passing to the function.

But it was not working for me. You need to use the Refresh() method if you need the control fully painted before you take the next step.

2008-03-17T16:02:00.000+05:30

When I tried to host a WebService and then to check it in the browser I got the content of the file rather than the list of WebMethods.

To solve this, first check whether the asp.net version is set in the website properties in IIS.

If your problem is not solved (most probably you install IIS after installing .net) run "aspnet_regiis.exe -i"(it will be there in your .net frame work folder) and then run "iisreset".

This fixed my problem.
