Trying to restrict port range used by Net.Tcp ListenUriMode.Unique

Posted By:      Posted Date: April 14, 2011    Points: 0   Category :SharePoint
We have internal firewalls which will normally only have restricted port ranges open. I am trying to restrict the tcp port range using the 'netsh int ipv4 set dynamicport' command. WCF seems to be ignoring these settings. How do I get WCF to restrict its port usage to a particular range of ports?

Unique content within master page based on conditions met


 Hi all-

I would like to present users with unique content based on certain conditions being met as they land on the home page (default.aspx).  The condition logic will be in the VB code behind Page Load event. The content will go in a content placeholder as specificed from the master page. 

However, the content change wouldn't be something small (ie making a panel or label visible or not) but rather it will be different HTML,  Divs and databound gridview content.  The HTML content will be stored in the database.

Can someone point me in the right direction for best practices on how to accomplish this?


Unique ID throughout entire request



I am hoping somene here could advise me on a better solution to my present problem.  First a little background information on the application. 

I have a web application using the 3.5 framework.  The structure of this application is as follows: UI -> WebService   -> Business Layer -> DataAccess Layer.   What I want to accomplish is for every request (click on a link or button) have a unique identifer that follows this request through its entire lifecycle.  This unique identifer can be accessible anywhere within this request.  We use Response.Redirects which could easily be changed to Server.Transfers (although I do not want to do that) but  the problem lies with the web service calls.  Currently, a GUID is set in the ApplicationRequest.  This GUID checks for a guid value in the RawURL and if so, assigns this value to a HttpContext Item.  If not, HttpContext.Items gets a new one created.  However, this idea is wrong and will need to be revisisted.  The bigger problem is with the web service calls.  Without changing every web service method signature, and every call for that matter, is there a way of getting this GUID there.  I created a web method in every web service so that each time I instantiate a web service object in the UI, before calling any

ListViewControl - how to group items by their value, for eg. date range



I have a table containing courses, columns are 

Name - "Yoga Classes"

DateStart - "2/23/2010"

DateEnd - "2/24/2010"

I am using ListView Control to bind it, is there a way to display them and group them by Month? 

for eg.


Piano Class (10th Jan 2010 - 11th Jan 2010)
Guitar Class (10th Jan 2010 - 11th Jan 2010)


Yoga Class (15th Feb 2010 - 16th Feb 2010)

Thanks for help.

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!

System.DateTime.AddDays: Value to add was out of range.


I'm getting the following error:

[ArgumentOutOfRangeException: Value to add was out of range.
Parameter name: value]
   System.DateTime.Add(Double value, Int32 scale) +7657639
   System.DateTime.AddDays(Double value) +19

The line from which this error originates has the following code:

expires = Now.AddDays(30)

It occurs irregularly and irreproducably. The server date/time is correct and set to GMT. I've heard that it could be some curiosity to do with timezones, but that is speculative.

It seems that we're some time from the year 10,000 yet, so I can't understand why adding thirty days to the current time could cause this! Any ideas? Culture settings perhaps?

Can a WCF service listen to TCP port??


Hello everyone,

need your replies as early as possible.

I have to develop a WCF Service which should listen to a particular TCP port for data coming in from clients. Is there a way wherein the client need not call any WCF Service methods, instead client can directly write data to that port and WCF listens to TCP port for data.

Prompt reply will be highly appreciated... Thanks!


reusable components and unique ids


I'm trying to create reusable "zones" but am having trouble figuring out how to give them all unique ids.

What I'd like is to be able to create a component which can be put on an mvc page using the usercontrol syntax or using RenderAction or RenderPartial.  I want to be able to update these components' content using ajax, so I need someway to reference them by id.  However, there is no mechanism in MVC that wraps anything in a div or something like that.

I've learned that if I extend ViewUserControl and put the controls on the page like so:

<Zones:TestControl runat="server" ID="TestControl1" />

Then I can use the 'ClientID' property to get the unique ID generated.  However, if I use RenderAction or RenderPartial in another request, obviously the control hierarchy is missing, so the ID is just 1.  So to get around this I made a simple base class like so:

public class BaseZone<TModel> : System.Web.Mvc.ViewUserControl<TModel>
        protected string zoneId;

        public string ZoneId
                string zoneId = ViewData["ZoneId"] as string;
                if (String.IsNullOrEmpty(zoneId))
                    return this.C

Problems creating a BDC file that use a unique select statment


I'm trying to build an BDC file that will pull information back from two tables in an Oracle database, I can import it without any errors, but then it tells me I do not have a filter when I try and select an item.  When I add a filter I get an error when I import the file.  The error I get is the following.
"Application definition import failed. The following error occurred: The IdentifierName Attribute of the TypeDescriptor named 'TestDate' of the Parameter named ':TestDate' of the Method named 'Get_TestTwelve_List' of the Entity named 'TestTwelve' does not match any of the defined Identifiers for the Entity. Error was encountered at or just before Line: '133' and Position: '16'."

Here is the section of

Calculated Columns in a Form Library receive error: Value does not fall within the expected range.


I have a forms library that posts the date the form was created. We would like to create a calculated column that allows us to look at these forms based on the month and year they were created. I had created a calculated column that extracts the month and replaces the number with a text string by using an if statement; "IF(MONTH([Proposal Date])=1,"January","") It goes on to evaluate each month and replace the number with the text string. This formula worked for quite some time, though now when I try to add any calculated columns or edit any existing calculated columns on this form library I receive the following error: Value does not fall within the expected range. Now my existing calculated columns (like the one above) do not work and I can not create new calcualted columns. Any insight would be awesome as this has been plaguing me for a couple of months now.
