Reading a file from external url – ASP .NET

manik — Sun, 14 Feb 2010 18:49:30 +0000

Often times you might need to read a file from another website server. For example reading a inventory data file from a vendor website. Here is a sample code to achieve that.

WebResponse result = null;
string output = “”;

try
{
WebRequest req = WebRequest.Create(“http://www.website.com/filename.txt”);
result = req.GetResponse();
Stream ReceiveStream = result.GetResponseStream();
Encoding encode = System.Text.Encoding.GetEncoding(“utf-8″);
StreamReader sr = new StreamReader(ReceiveStream, encode);
Char[] read = new Char[256];
int count = sr.Read(read, 0, read.Length);
while (count > 0)
{
String str = new String(read, 0, count);
output += str;
count = sr.Read(read, 0, read.Length);
}
}
catch (Exception)
{
Response.Write(“get failed”);
}
if (result != null)
{
result.Close();
}

Response.Write(output);

How to apply multiple css styles on single element

manik — Fri, 22 Jan 2010 22:47:03 +0000

If you like to apply multiple styles on the single element, all you have to do is separate the style names by a space.

Example:

Lets say you have three classes

.a {..}
.b{..}
.c{..}

To apply them on a single div tag:

How to add an additional ip address in windows server 2003 and 2008

manik — Fri, 22 Jan 2010 19:46:44 +0000

If you have a dedicated server and you need to add an additional ip address, first thing to do is request for the additional ip address from the hosting company. Often time they would not hook it with your server, they would just give it to you.

So how you add the additional ip address to your windows server?

These steps are for Windows Server 2003.

Click on Start button
Open Cotnrol Panel
Open Network connections
Select Local Area Connection (for first Ethernet card)
Right Click and select Properties
Select Internet Protocol (TCP/IP)
Now click on Properties button
Click on Advanced tab
Now you need to add in an IP address section Enter IP details such as IP address, Subnetmask etc
Save the changes and go back to Windows server desktop

These steps are for Windows Server 2008.

Click on Start button
Open Cotnrol Panel
Click on Network and Sharing Center
Click on Manage Network Connections
Right Click on the active network icon and select Properties
Select Internet Protocol Version (TCP/IP). There may be more then version. For me there are 4 and 6. Mine one is at 4.
Now click on Properties button
Click on Advanced tab
Now you need to add in an IP address section Enter IP details such as IP address, Subnetmask etc
Save the changes and go back to Windows server desktop

After that you need to verifty that new settings are working. This is how you do that:

Open command prompt
Click on Start button
Select Run
Type cmd and press enter
Type the following command at DOS prompt: ipconfig /all

Maximum Int Value MS SQL

manik — Fri, 22 Jan 2010 14:37:24 +0000

When you design database tables care should be taken selecting the type of integer columns. If you predict there is chances to have big numbers on the integer column, consider bigint or int accordingly. Of course there are performance issues involved to consider.

Here are the maximum int value in MS SQL server.

bigInt -9223372036854775808 through 9223372036854775807 (8 bytes)
int -2147483648 through 2147483647 (4 bytes)
smallInt -32768 through 32767 (2 bytes)
tinyInt 0 through 255 (1 byte)

Neglecting Improving Websites

manik — Thu, 21 Jan 2010 22:51:53 +0000

Being an entrepreneur web developer has some advantages, I don’t have to pay anybody for the web development works. In the past I have developed some websites with great features; take webcosmo.com or shoppingcosmo.com for example. All those sites are custom made. Lot of people would spend tons of money to make those sites.

I guess with all good comes bad. My problem is before I monetize the websites well I jump into another business idea that comes in mind. That’s not a good business decision at all.

I have set a goal of getting those neglected websites back on track.

Is it only me or you guys also do the same thing?

Background does not extend beyond viewport

manik — Wed, 13 Jan 2010 22:07:28 +0000

While working on a client website got into this situation.

I have two backgrounds for a page; one on left side, another on the right side. Both repeat vertically. This is an example how I have set the code at first:

“http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd”>

2 columns, fixed width, right rail, content tallest

Bla Bla Bla…

Problem:

Everything works fine as long as we dont have a scrollbar on the right. When we have lot of content that makes the browser have a scrollbar, the background on the right does not seem to repeat; it ends at the end of the viewport.

Basics of Percentage Height:

Anytime you want to declare a percentage height of an element you must declare a dimension set for it’s parents as well(no necessarily by percentage). For example if you want to set 100% height for a div that is inside the body tag, you must set a dimension for the body as well as html tags as well.

bla bla bla…

And the css for that:
html, body {height: 100%;}
.adiv {height:100%;}

Solution:

We like our div to be at least as high as the viewport, but if the content is longer than the viewport, stretch to contain it. CSS provides a way for us to do that with the min-height property. If we change the height: 100% in the #container rule to min-height: 100% everything is pronto. The code would look like this:

“http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd”>

2 columns, fixed width, right rail, content tallest

Bla Bla Bla…

Two Cloumn Equal Height Layout With CSS

manik — Mon, 11 Jan 2010 17:43:21 +0000

I wanna create a two column layout using CSS. Both clumns would have equal height. This is how we can do it:

“http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd”>

Two Cloumn Equal Height CSS Layout

This is left div 1 content
This is left div 1 content

This is div 2 content

border-right:150px solid #c33;
This line of code just gives a color to the div2.

margin-right:-150px;
This line of code create space on the right for div2.

Other then that everything else is self explanatory.

the type or namespace name ‘webmethod’ could not be found

manik — Sat, 19 Sep 2009 00:16:27 +0000

If you are adding Page Method on your ASP .Net page and you see this compile error:

the type or namespace name ‘webmethod’ could not be found….

then you are missing one of these things:

A. Make sure you have reference to System.Web.Services on your class.

using System.Web.Services;

B. Make sure on your web.config you have

C. Make sure you have EnablePageMethods set to true on your ScriptManager

Truncate MS SQL 2008 Database Log File

manik — Wed, 16 Sep 2009 22:10:56 +0000

If you need to truncate the SQL database log files to keep them smaller in size. The process I am demonstrating here is for MS SQL 2008.–Get in the database

use Test
GO

–see current file sizes
SELECT name,size from sys.database_files

–see current recovery model
select name,recovery_model_desc from sys.databases

–According to the articles if you switch the Recovery Model to Simple inactive part of the transaction log should be removed in MS SQL 2008.
–This command will reduce the log file somewhat
Alter database Test SET Recovery simple

–check if the recovery model is changed
select name,recovery_model_desc from sys.databases

–check file sizes
select name,size from sys.database_files

–changing the recovery model to Simple might not reduce the size enough. to reduce it further
DBCC SHRINKFILE (N’Test_log’ , 1)

–check file size
select name,size from sys.database_files
