'asp' is an unrecognized tag prefix or device filter


Hi There,

I have been using Visual Web Developer Express Edition Beta 1 Refresh and Visual Studio 2005 Beta 1 for the past few weeks. For some unforeseen reason VS now reports the error -'asp' is an unrecognized tag prefix or device filter on all my .aspx pages.

The solution compiles and launches without any mishap and the only way to alter page control properties is in design view, as intellisense does not function due to the errors.

I've search the web and found a resolution which was to remove all files in the folder:

C:\Documents and Settings\[Username]\Application

But the issue still exists.

Any assistance would be greatly appreciated.



Using jQuery to Filter Table Rows

The project is using the .net GridView control, so I had limited control over the output HTML code. Still, I think this code can work for most tables. One thing to notice: you should use the class "filterable" on your table or on one of its parents for the code to work.
First, we need a text box:

GridView Multiple Filter AJAX Control

This AJAX control enables the user to filter data within any column inside a GridView. The user can add multiple filters and can delete existing ones too.

Draw lines excactly on physical device pixels

When you draw a line in WPF you will experience that they often appear blurry. The reason for this is the antialiasing system that spreads the line over multiple pixels if it doesn't align with physical device pixels.

How to create a windows mobile (Smart Device) .Cab installer

A Cab file is the default setup format for Windows CE and Windows Mobile devices (similar to windows .msi files). You probably already have installed several application using .cab files, and are familiar with the concept. One point which is often unknown is that .cab files are processed by wceloader.exe, and it can only install one .cab file at a time. That means we cannot have nested .cab files. It doesn't mean we cannot have .cab files contained by another .cab, but the contained .cab files will not be installed during the installation of the container .cab. We should install it manually after the container .cab file installation has been completed.

There are two ways to create a cabinet (.Cab) file. The traditional one, and the friendly VS Smart Device Cab project which doesn't require additional coding, but which also relies on the traditional one at low-level.

How to transfer files between computer and mobile device using bluetooth

What is Bluetooth? How can I have it on my computer?

Bluetooth wireless technology is a communication technology that allows two devices to communicate wirelessly. Most of the notebooks are nowadays equipped with bluetooth. For those notebooks or computers that don't, you can use a bluetooth dongle to add the functionality and it just costs you around $5. Although higher price range bluetooth dongles are available but it makes no sense of buying them if you just plan to connect your mobile device to the computer. Look for one that has Bluetooth v2.0 + EDR (Enhance Data Rate) supporting speeds of upto 3Mbps and with Vista support. You can easily have one of that kind in just $5.

Setting up bluetooth to work on your computer

Just Insert the bluetooth dongle in the USB.
It should get detected by your Operating System and should be ready to use. In case it is just detected as a new hardware, you need to install drivers for it that came with your bluetooth dongle (You can try Google to find the drivers).
Once drivers are installed, a bluetooth notification icon will appear in your system tray.
Right Click on it to access Settings (This may vary with your bluetooth dongle).
Make sure you have turned Discovery On (It allow others to see your computer).
Switch On the bluetooth on the mobile device.

Where to Filter the companies returned by the EF?



I am just starting with dynamic data. I have an enttity framework called UsersModel.edmx.

It returns a list of all companies in the tblCompany table. This list is really big.

I need to filter the list returned to all user controls on the client so that it only returns the company that have a CompanyTypeId= 2 or CompanyTypeId= 3 and company name != "".

1 - Is it possible to filter the company list returned on the server so that I can filter only once for all the controls that use that on the client?

My ideas was to do something like this using linq and lambda but I am not sure how:

return tblCompanys.Where(c => c.CompanyTypeId == 2 || c.CompanyTypeId == 3 && ).Where(c=>c.CompanyName != "").OrderBy(c => c.CompanyName).Distinct().OrderBy(c=>c.CompanyName);

2 - I have created a partial class and a metadata class and added the DisplayColumn attribute to use the company name and sort by company name ascending.

Could I use the code to filter the returned companies in this? where?

namespace MarsMedicalModel
    [DisplayColumn("CompanyName", "CompanyName")]
    public partial class t

Filter by Computed Column



After looking for a driver to open legacy dbf drivers to connect, the next level trouble a have is this one:

first, i can retrieve the data but when trying to filter by a parameter (somesc columns) i get an error.

The error says about the database can't determine some blah blah!

The error is a columm tha is formated (  1234  ) about  8 space, fixed. The values in the query appears like that. I resolve this by Trimming Ltrim(ColumnName) and i get this (1234).

Now in SqlExpress, how can i filter by the new Trimmed Expression? (This is a primary key that the DBF use)


SELECT column1, column2, column3


SELECT Ltrim(column1) as NewExp, column2, column3
Where NewExpre = @NewExpres                  -Error-


LDAP nested groups filter


Hi all,

In my organization we use nested groups.

For a particular usage, we have a group (let's assume that the group name "kuku"), and the names of all the nested groups under it contains "kuku" as well.

We may assume that no other group in the LDAP has "kuku" in the name.

I need to create a filter which will return all the users which belong to one of the "kuku"s group.

Obviously, using this filter will bring only the head kukus

(&(&(objectclass=user)(objectclass=person))(memberOf=CN=kuku,cn=.rest of the group DN.))

How can I use wild card to fetch all users which belong to any kuku?

For example: (&(&(objectclass=user)(objectclass=person))(memberOf=CN=.*kuku.*))

Device detection: standard & mobile web applications


I would like to host standard web pages as well as mobile web pages on a single website/virtual directory.


Is there a simple way of sniffing out the machine type and then presenting either web or mobile application depending on the device?

Or is there a better solution other than creating separate website?

Many thanks

Detecting PPC device on startup page to redirect?

I was wondering (since a search didn't find any posts) if there is a way for my startup page to detect what kind of device (PocketPC or web browser specifically) is loading the page and if it is a PocketPC, then redirect to the mobile pages? I will only be using PocketPC's exclusively as a mobile device.

Thanks for any suggestions!

Create web site specific to mobile device, how to detect?



I have a website that is written in .Net 2.0 which uses all the nice rich functionality of the web (Ajax, javascript etc..).  However I have noticed that the site does not display very well on mobile devices. 

So therefore I would like to create a more streamlined version of my site that is better tailored to these devices.  However how do detect that the user has come to the site via a mobile device and how can i redirect them to my tailored page

Many thanks in advance
