Posted By:      Posted Date: September 20, 2010    Points: 0   Category :ASP.Net

Hi I   find days missing between dates for expamle. 10 may 2010 , 11 may 2010, 13 may 2010 , with this code

                List<DateTime> dateTimes = new List<DateTime>();

                foreach (String sDate in s)
                    dateTimes.Add(DateTime.ParseExact(sDate.ToString(), format, CultureInfo.InvariantCulture));

                //Check for missing dates thats will indicate an Overlap Booking

                for (int i = 1; i < dateTimes.Count; i++)
                    if ((dateTimes[i] - dateTimes[i - 1]).TotalDays != 1)
                        DateTime start = DateTime.Parse(txtStart.Text);
                        DateTime end = DateTime.Parse(lblEnd.Text);

                        ConstructTable(start, end);
                        //btnBook1.Visible = true;
                        lblError.Text = "Bookings May Not Overlap";

Find week number in xpath from two dates in SharePoint 2010



I am trying to determine the week of the year from two dates. The first date will be the first day and month of that year (e.g. 01/01/2005) and the second will be the date of a document(05/05/2005). We tried to accomplish this same task within SharePoint, not using the SP Designer, however, we could not because we could not utilize the name column. Anyhow below is what I got so far. I search for a date function to perform subtraction but could not find any. Thank in advance.

Content Query Web Part missing in SharePoint 2010

If you don't see content query web part listed in the web parts list, this is because you have not enabled "Search Server Web Parts" feature in site collection features. Enable this feature and content query web part will show in the list of web parts.

Missing 'new item templates'


 Hi all,

          I am a 'newbie' to VWD and I am slowly working through the Basic Walkthrough Help files, and learning plenty along the way.

However, when I tried to create a new database in the LINQ control walkthrough I found that the option to create a new database is missing, and further investigation has found that many other new item templates are missing.

I am using a brand new machine with Windows 7 Ultimate and have enabled IIS and .NET from Control Panel-Programs-Turn Windows Features On-Off. I used the WPI to install all basic elements eg. IIS Components, SQL Server Express.

The only 'new item templates' I have when I right-click the App_Data Folder and choose 'new item' are:-

ADO.NET Data Service

AJAX Enabled WCF Service

Dynamic Data Field

SQL Server Database

Text File

XML File

Does anyone know where I have gone wrong.

Using loginName to find ADInfo from an outside class



I wrote a class to pull adinfo and for the life of me I can't seem to figure

out why it says "Invalid Login Name" no matter what I type in. If I leave

it blank it seems to work properly but it doesn't seem to be actually searching

the AD. I'll drop the whole class here, it's being initiated by a button click

on an outside form.


Thanks in Advance for any help Offered,

LDAP - Can't find server


Hey people,

I would like to get a persons name from their username - a common query on forums i know, but i haven't managed to get mine working yet and any help would be appreciated.

I currently have this code that I found here: http://www.vbforums.com/showthread.php?t=612655 (Thanks Chris128)

I have adapted it from VB into VB.net. The page renders but when i enter my username into the Username textBox and hit the submit button (Which calls IsUser) I just get "The specified domain either does not exist or could not be contacted." I have tried lots of other code but I always get this response...

If anyone can help by posting links to a tutorial or another post for code that they know works, i will give it a go.

Could not find default endpoint element that references contract 'CurrencyProxy.CurrencyServiceSoap



I created 2 projects in my solution:

  1. Classic asp.net web service (asmx)
  2. Class library project which references service
  3. web site project which references class library project
  4. Windows app project which references service.

Both projects were created in 3.5 framework and in Visual Studio 2008 Beta 2.

I added web service reference to Class library project. When it asked for namespace I typed "CurrencyProxy". Projects build ok, but when I run web app, Class library throws an error: Could not find default endpoint element that references contract 'CurrencyProxy.CurrencyServiceSoap' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element.

I believe it has something to do with app.config in Class library project. Here is part from app.config:

<binding name="CurrencyServiceSoap" closeTimeout=

Cant find vsi file for CSS Friendly Control Adapters


Hi guys

This is driving me crazy... I cant find the .vsi file for installing the CSS Friendly Control Adapters Project. Does anyone know where I can get this?

The following link: http://www.asp.net/cssadapters/ only leads to the CodePlex wiki where I can download the dll and a partial solution. Essentially, I'm looking for the source code to implement the Menu adapter.

Any help is much appreciated!
