FIREFOX asking for password at localhost IIS

2008-07-10T15:39:18+01:00

Firefox - Enter username and password for "" at http://localhost - Solution

IIS uses Integrated Authentication and by default IE has the ability to use the windows user account. Firefoc can do the same after doing this:

1) Open up Firefox and type in about:config as the url

2) In the Filter Type in: ntlm

3) Double click "network.automatic-ntlm-auth.trusted-uris" and type in localhost and hit enter

2008-05-06T14:49:39+01:00

I am running the query SQL="Select name from profile where proID=1"; and I am getting the result in Dataset dsdata. How can I read the text from the dataset and assign it to textbox1.text ?

VB.NET

Textbox1.Text= dsData.Tables(0).Rows(0)("FieldName").ToString()

TextBox1.Text=dsData.Tables[0].Rows[0]["FieldName"].ToString();

SQL CONCAT

Concatenating Strings

String concatenation functions used in various databases and their conversion by SQLWays.

SQL Concatenating Strings
Database	Syntax	Description
Oracle	exp1 \|\| exp2 [\|\| expN]...	Returns the concatenation of two or more expressions of CHAR, VARCHAR2, CLOB data type. Return type: · If all expressions (for example exp1 and exp2) are of data type CHAR, the result has data type CHAR and is limited to 2000 characters. · If either expression is of data type VARCHAR2, the result has data type VARCHAR2 and is limited to 4000 characters. · If either expression is CLOB, the result is CLOB.
Oracle	CONCAT (exp1, exp2)	Returns exp1 concatenated with exp2. Both exp1 and exp2 can be any of the datatypes CHAR, VARCHAR2, NCHAR, NVARCHAR2, CLOB, or NCLOB. Return type: · The string returned is in the same character set as exp1. Its data type depends on the datatypes of the arguments. · In concatenations of two different datatypes, CONCAT function returns the data type that results in a lossless conversion. · Therefore, if one of the arguments is a LOB, then the returned value is a LOB. If one of the arguments is a national data type, then the returned value is a national data type. CONCAT function is equivalent to the concatenation operator (\|\|).
MySQL	CONCAT(exp1, exp2 [,expN]...)	Returns the string that results from concatenating the arguments (expressions). Returns NULL if any argument (expression) is NULL. A numeric argument is converted to its equivalent string form.
Microsoft SQL Server	exp1 + exp2 [+ expN]...	Returns the concatenation of two or more character or binary strings, columns, or a combination of strings and column names into one expression (a string operator). expression (exp1, exp2, ..., expN) - is expression of any of the data types in the character and binary data type category, except the image, ntext, or text data types. Both expressions must be of the same data type, or one expression must be able to be implicitly converted to the data type of the other expression. An explicit conversion to character data must be used when concatenating binary strings and any characters between the binary strings. Return type: the data type of the argument with the highest precedence. The precedence order data types is following: · sql_variant (highest) · datetime · smalldatetime · float · real · decimal · money · smallmoney · bigint · int · smallint · tinyint · bit · ntext · text · image · timestamp · uniqueidentifier · nvarchar · nchar · varchar · char · varbinary · binary (lowest)
IBM DB2	CONCAT (exp1, exp2) exp1 \|\| exp2 [\|\| expN]... exp1 CONCAT exp2 [CONCAT expN]...	Returns the concatenation of two or more string arguments. Arguments must be compatible types. The result of the function and operator (\|\|) is a string. Its length is the sum of the lengths of the two arguments. If either argument is null, the result is the null value. Note: a binary string cannot be concatenated with a character string, including character strings defined as FOR BIT DATA.

MySQL: CONCAT()
Oracle: CONCAT(), ||
SQL Server: +

The syntax for CONCAT() is as follows:

CONCAT(str1, str2, str3, ...): Concatenate str1, str2, str3, and any other strings together. Please note the Oracle CONCAT() function only allows two arguments -- only two strings can be put together at a time using this function. However, it is possible to concatenate more than two strings at a time in Oracle using '||'.

Let's look at some examples. Assume we have the following table:

Table Geography

region_name	store_name
East	Boston
East	New York
West	Los Angeles
West	San Diego

Example 1:

MySQL/Oracle:
SELECT CONCAT(region_name,store_name) FROM Geography
WHERE store_name = 'Boston';

Result:

'EastBoston'

Example 2:

Oracle:
SELECT region_name || ' ' || store_name FROM Geography
WHERE store_name = 'Boston';

Result:

'East Boston'

Example 3:

SQL Server:
SELECT region_name + ' ' + store_name FROM Geography
WHERE store_name = 'Boston';

Result:

'East Boston'

he Substring function in SQL is used to grab a portion of the stored data. This function is called differently for the different databases:

MySQL: SUBSTR(), SUBSTRING()
Oracle: SUBSTR()
SQL Server: SUBSTRING()

The most frequent uses are as follows (we will use SUBSTR() here):

SUBSTR(str,pos): Select all characters from <str> starting with position <pos>. Note that this syntax is not supported in SQL Server.

SUBSTR(str,pos,len): Starting with the <pos>th character in string <str> and select the next <len> characters.

Assume we have the following table:

Table Geography

region_name	store_name
East	Boston
East	New York
West	Los Angeles
West	San Diego

Example 1:

SELECT SUBSTR(store_name, 3)
FROM Geography
WHERE store_name = 'Los Angeles';

Result:

's Angeles'

Example 2:

SELECT SUBSTR(store_name,2,4)
FROM Geography
WHERE store_name = 'San Diego';

Result:

'an D'

The TRIM function in SQL is used to remove specified prefix or suffix from a string. The most common pattern being removed is white spaces. This function is called differently in different databases:

MySQL: TRIM(), RTRIM(), LTRIM()
Oracle: RTRIM(), LTRIM()
SQL Server: RTRIM(), LTRIM()

The syntax for these trim functions are:

TRIM([[LOCATION] [remstr] FROM ] str): [LOCATION] can be either LEADING, TRAILING, or BOTH. This function gets rid of the [remstr] pattern from either the beginning of the string or the end of the string, or both. If no [remstr] is specified, white spaces are removed.

LTRIM(str): Removes all white spaces from the beginning of the string.

RTRIM(str): Removes all white spaces at the end of the string.

Example 1:

SELECT TRIM(' Sample ');

Result:

'Sample'

Example 2:

SELECT LTRIM(' Sample ');

Result:

'Sample '

Example 3:

SELECT RTRIM(' Sample ');

Result:

' Sample'

Visual Studio - Missing Item Template

2008-04-09T00:12:59+01:00

If you are missing templates, these could help (try one of these):

1) Open the Options window in Visual Studio.
Select Projects and Solutions.
Change the Visual Studio user item template location (Path .... \Documents and Settings\WINDOWSUSER\My Documents\Visual Studio 2005\Templates\ItemTemplates)
to the folder where the standard templates are located ( C:\Program Files\Microsoft Visual Studio 8\Common7\IDE\ItemTemplates ).

After the change, all templates will be accesible.

2) Open a new ‘Visual Studio 2005 Command Prompt’. Once there type the following command at the prompt, press enter and wait…

devenv /installvstemplates

This will rebuild your item and project template cache.

3) Install "VS80-KB915364-X86-ENU.exe" and then install "WebApplicationProjectSetup.msi"

WWW-sisällönhallinta

Www-sisällönhallinta tarkoittaa toimintaa jossa verkkopalvelun sisältöjä pyritään hallitsemaan mahdollisimman tarkoituksenmukaisesti. Www-sisällönhallinta on luonteeltaan julkaisupainotteista sisällönhallintaa. Www-sisällönhallinnassa keskeisessä asemassa ovat sivupohjat jotka koostavat pienistä
sisältöyksiköistä www-sivut ja pitävät verkkopalvelukokonaisuuden kasassa. Www-sisällönhallinnan käytännön toteutukseen liittyvät olennaisesti erilaiset www-sisällönhallintajärjestelmät.

Www-sisällönhallinnalle tyypillistä on myös sisältöjen, rakenteiden ja ulkoasun erottaminen toisistaan. Sivupohjien avulla toteutettava kokonaisuus mahdollistaakin esitysmuotojen yhtenäisyyden ja keskitetyn ylläpidon. Esimerkkejä tyypillisistä sivupohjien sisällöistä ovat muun muassa navigaatio-elementit,
kaikilla www-sivuilla toistuva grafiikka kuten logot, taustavärit ja muotoilut, www-sivujen otsikot, pudotusvalikot, linkit yhteystietoihin ja www-sivuilla olevat vaihtuvat mainokset.

Sivupohjiin perustuva julkaisu mahdollistaa useiden erilaisten päätelaitteiden ja jakelukanavien huomioimisen, ja tästä syystä www-sisällönhallinta liitetäänkin usein monikanavajulkaisuun.
