Foundations: Render Text On A Path With WPF

Posted By:      Posted Date: August 21, 2010    Points: 0   Category :ASP.Net

With Windows Presentation Foundation (WPF) you can lay out text on a path, then animate the individual points defining the path and watch the characters bounce around in response.

Render XML text *inside* of an ASP.net page?


I have a block of XML text I need to show the user (so they can copy/paste the XML from the screen)

I use StringWriter() to make the XML a String but when I use Response.Write(xmlString) I get the following error

Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.
Details: Error parsing near '<?xml version="1.0" '.

I guess IE does not like rendering XML in the middle of a page?

is there anyway to show the XML data in the middle of my ASPX page?

Many thanks! :)

Flow Document text parsing to render XML documents with foreground color


I need to display some XML in a flow document in read-only mode. Would like to render it with the black, red and blue formatting based on the contents / keywords. I know you can set the foreground color with span elements.

Is there a way to achieve this in a object oriented / dynamic way ? Like you set the content of flow document/paragraph element and it automatically parses the text and sets the foreground color for specific keywords. I am thinking of starting a prototype project with the help of converters - not sure if it can give an extend-able model (for maybe T-SQL someday). May probably have to inherit from flow document and create a custom / user control.

Any thoughts, help or tips would be greatly appreciated.



AutoCompleteStringCollection for text box in DataGridView 2.0

I have been searching for a way to have autocomplete in a DataGridTextBox
object. There does not appear to be an obvious way to do this like you would
for a TextBox outside of a grid using the AutoCompleteCustomSource. Any
thoughts on how I can add this collection? :)

Built-in Functions - Text and Image Functions in SQL Server

Text and image functions operate on TEXT, NTEXT and IMAGE data types. These data types are deprecated with SQL Server 2005 and should be replaced by VARCHAR(MAX), NVARCHAR(MAX) and VARBINARY(MAX) when possible. Alternatively you can also consider storing large string values using XML data type. Text and image functions are nondeterministic.

Future versions of SQL Server will not support TEXT, NTEXT and IMAGE data types. Columns with TEXT / NTEXT data type do not support commonly used string functions such as LEN, LEFT, RIGHT, etc. Furthermore, due to the large size of TEXT data you''re likely to see performance issues if you store such data in the database. However, at times you can''t help but use the TEXT / NTEXT / IMAGE data types (for example when supporting 3rd party databases when you cannot change the schema) - this is when text and image functions come in handy.

P.S all the effect have the same render problem, and i am using ie8 under compatibility mode.





reference from menubuttons to text parts in article on the same page


Hi, I'm searching now for hours but couldn't find it.Cry

In my menu i have several buttons which (by a <a href..) should go the a part of an article that is in the same form.

Menu button : What is a database should go to the page default.aspx and in there is an article published.
A part of this article is having a piece of text about "what is a database"

Menu button: how to make a query should go to this same article in the same page but then to the part that is have the piece about the query. The next could be an example of what i'm doing:

    <li><a href="default.aspx ?????>what is a database</a></li>
    <li><a href="default.aspx ?????>what is a query</a></li>

Where my question marks are, there should be a connection to that particular piece of text.
In each article part there is an ID="text1" and the second part id="text2"

How shoudl i do that, Should i use a question mark.
Please give me some guidance how to structure the <li> statement or a pointer where I can read about it.


text editor


 I format lines in a .aspx file (source view) the way I can use them, and if I switch to design view or view in browser or debug, the many lines get reformatted to flow all onto one line.

I can't seem to find the correct setting to keep this from happening.

Any suggestions?


Creating a user friendly alias for the website path


 Hello mates,

I am hosting my ASP.NET application on a Windows 2003 Server.

To browse to my application one has to type the path :http://serverName/applicationName

I want users to only type  applicationName on the web adress area.I believe there is something to do with alias and CNAME on DNS records that can adress this.

Any help on how to go about doing this will be highly appreciated.

Unique text value in databse column


Hi Everyone!

I know this is probably a very basic question but how do I keep a column's text values unique in SQL server (ie for a unique username)?  The column is not an integer it's varchar(50), and it's not the primary key but I could make it the primary key if recommended.

The front end could handle it;  where the user would enter text, it's validated, then a query is done to see if that username is available.  If so, then user can decide to choose it and an insert is done, if not they pick a new username and process repeats.  With this approach, the responsibility of keeping the value unique solely rests on the front end, nothing on the database side.

Is this the correct way to handle this? 

Thank you!


How to set SearchRoot Path in Active Directory in this scenario


How to set SearchRoot Path in Active Directory in this scenario:

Functionality: We have scenario that 1<sup>st</sup> hit one LDAP server with some 'fixed user name' &' fixed password ' and filter data with specific User name(which given by user) getting 'User dn'.

After that we hit Next LDAP server based on the 'User dn' getting from 1<sup>st</sup> server.

(So, in my case 1<sup>st</sup> LDAP server works like as Load balancing server but functionalitywise it is different)
