Increase Netbook Screen Resolution

Leave a reply

Do you want to increase netbook screen resolution? The you can follow this simple steps but its only working on windows 7/Vista.

  1. Press WINDOW KEY + R this will open a Run Prompt
  2. On that Run Prompt type regedit
  3. Go find the registry for Display1_DownScalingSupported
  4. After find that change its value from 0 to 1
  5. FIN!

Just a note that the searching may take a little time. And remember that Increased resolution is just a software based emulation so expect that your screen will look somewhat funny after changing to a higher out of scope resolution.

Thanks,

Creating a file to Download dynamically in an https / SSL connection

Leave a reply

Hi there, 

Here is a tip when you are programming something that you want your file’s path to be hidden. It’s specially when its under a secure connection or https or SSL connection.

  1. Remember the mime type ea. image/jpg
  2. Remember the file name ea. image.jpg
  3. Remember not to put expiration and no-cache on your header
  4. Remember to open it on another tab or window as much as possible
  5. When you are debugging you can remove the headers so the file won’t be downloaded

Hope this tips can help you specially #3 because your download will fail on lower version of IE.

Thanks,

A potentially dangerous Request.Form value was detected from the client

Leave a reply

Have you ever experience the following error in ASP .NET?

A potentially dangerous Request.Form value was detected from the client 

Then you are one like me. Then you should now that one of the values of your elements (<inputs> or <button> or <textarea>) has html elements on it. Example is bellow:

<input type=’text’ name=’content’ value='<script language=”javascript”>alert(“Hello World!”);</script>’/>

Then you should also know that this error is persisting because the values given above might be an XSS attack. If you are sure that you want to accept this type of values on your dabatase you may explicitly remove this validation by adding this tag to your page’s masterpage or 1st line of tag.

validateRequest=”false”

If you are on ASP .NET MVC you can add this to your model, assuming that your model has the content variable.

[AllowHtml]
public string content = String.Empty;

Thanks hope it help you allot. Also if you are not familiar with XSS attacks, I will try to make an article for that so you can create your own script that is hack-able, be able to prevent it, and know what are it’s crons.

God Bless!

jStorage:An alternative for Cookies

Leave a reply

Have you ever wondered if there is an alternative for Cookies? 

You should, because there are limitation and downsides in using Cookies on your website that massively use this feature.

  1. Cookies has limited size on most browsers
  2. Cookies is transfer to server every page load
  3. If you overload the size of the Cookies it will also eat up the space of session and might remove it

Introducing jStorage, a jQuery way of saving your data to the local client and I quote

jStorage is a cross-browser key-value store database to store data locally in the browser – jStorage supports all major browsers, both in desktop (yes – even Internet Explorer 6) and in mobile.

Yes it even support IE 6!

So how to use it in an easy way?

  1. Include the following references to your project 
    1. <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.8.0/jquery.min.js"></script>
<script src="https://raw.github.com/andris9/jStorage/master/jstorage.js"></script>
  2. Use $.jStorage.set(key, value) to save a value 
  3. Use $.jStorage.get(key, “default value”) to get a value

And thats it you are now using jStorage.

WCF in Different Domain or Server

Leave a reply

Hi There,

Its bean a while since I have updated my blog so I will be posting one of the things that I have experience on my work. That is WCF in Different Domain or Server. One of the main error that you may experience is the same as bellow:

Server Error in ‘/’ Application.

The request for security token could not be satisfied because authentication failed.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.ServiceModel.FaultException: The request for security token could not be satisfied because authentication failed.

Source Error: 

Line 87:         
Line 88:         public bool IsExisting(string domain, string username) {
Line 89: return base.Channel.IsExisting(domain, username); Line 90:         }
Line 91:


Source File: D:\Projects\MobileWeb\MobileWeb\Service References\SykesAD\Reference.cs Line: 89

Stack Trace: 

[FaultException: The request for security token could not be satisfied because authentication failed.]
   System.ServiceModel.Security.SecurityUtils.ThrowIfNegotiationFault(Message message, EndpointAddress target) +8904771
   System.ServiceModel.Security.SspiNegotiationTokenProvider.GetNextOutgoingMessageBody(Message incomingMessage, SspiNegotiationTokenProviderState sspiState) +203

[SecurityNegotiationException: The caller was not authenticated by the service.]
   System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage(IMessage reqMsg, IMessage retMsg) +4729651
   System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke(MessageData& msgData, Int32 type) +1725

 

This message or exeception happens in production (published files has been uploaded to IIS) and not when you are currently developing it on your Visual Studio. So what is the solution? Here is the simple solution that made me a little crazy upon gazing unto it.

//Let say here is your Instantiation of your WCF
ClassADClient ad = new ClassADClient();
//Then the solution is to add a credential that the system will use on using the said WCF
//Such as like this
ad.ClientCredentials.Windows.ClientCredential = new NetworkCredential(“domain\\username”, “password”);

That’s it thats the solution and you can now use the said service without the said error.

Hope I help you! 

 

Thanks,

Don’t Ever use Inline Database in MSSQL SP and Query

Leave a reply

Hi there!

I have been modifying a source code from my work and it has been a little difficult to test the system in multiple instances of database. This is due the previous developers of the said source code used Inline Query Codes and Connection Strings. In addition to that this Inline Queries and even their Stored Procedure use Inline Database, an example is [Database1].[dbo].[tbl_tableName] which should not be in practice if it is using the same database on the whole coding system.

This kind of practice limits the system to use different database name. For an instance you have a web server that serves both Development and Production Environment. You have a project that needs to have Dev and Prod on the said server. If this practice is used you are limited to one Environment at a time nevertheless you modify each script to change that inline database name. So its better to use [dbo].[tbl_tableName]  than [Database1].[dbo].[tbl_tableName] 

Thanks,

Thomie

IIS Missing ASP .Net 4.0 Pool

3 Replies

Have you’ve been missing some pool in your IIS for your ASP .Net?

The this article entitle IIS Missing ASP .Net 4.0 Pool will help you.

Chances are, you need to install .NET 4 (Which will also take care of a new AppPool for you)

  1. Open your command prompt (Windows + R) and type cmd and press ENTER
    You may need to start this as an administrator if you have UAC enabled.
    To do so, locate the exe (usually you can start typing with Start Menu open), right click and select “Run as Administrator”
  2. Type cd C:\Windows\Microsoft.NET\Framework\v4.0.30319\ and press ENTER.
  3. Type aspnet_regiis.exe -ir and press ENTER again.
    • at this point you will see it begin working on installing .NET’s framework in to IIS for you
  4. Close the DOS prompt, re-open your start menu and right click Computer and select Manage
  5. Expand the left-hand side (Services and Applications) and select Internet Information Services
    • You’ll now have a new applet within the content window exclusively for IIS.
  6. Expand out your computer and locate the Application Pools node, and select it. (You should now see ASP.NET v4.0 listed)
  7. Expand out your Sites node and locate the site you want to modify (select it)
  8. To the right you’ll notice Basic Settings… just below the Edit Site text. Click this, and a new window should appear
  9. Select the .NET 4 AppPool using the Select… button and click ok.
  10. Restart the site, and you should be good-to-go.

(You can repeat steps 7-on for every site you want to apply .NET 4 on as well)

That’s it!

Thanks,

Windows 8 Consumer Preview on your PC?

6 Replies

Hi Friends!

Wondering if your computer can seamlessly run Windows 8 Consumer Preview on your PC? The should check this short specification that your computer should meet:

  • 1 GHz or faster processor 
  • 1 GB RAM (32-bit) or 2 GB RAM (64-bit)
  • 16 GB available hard disk space (32-bit) or 20 GB (64-bit)
  • DirectX 9 graphics device with WDDM 1.0 or higher driver
  • 1024 x 768 minimum screen resolution

Take note that 1024 x 768 resolution it alittle sad if your using a notebook because most notebook resolution is 1024 x 600 which doesn’t meet the said requirement. 

Later this day I will try to install it and tell you if it will work.

Also You may download it here

(64bit users) Download this if you are using morethan 4GB of RAM

(32bit users) Else Download this

Product Key:   DNJXJ-7XBW8-2378T-X22TX-BKG7J
