Option to using enums and switch statements?

Posted By:      Posted Date: October 26, 2010    Points: 0   Category :ASP.Net

Is there any design pattern or architectural design that prevent the following type of code, where I have an enum with different fileformats and I have to make a switch anywhere I want to distinguish between the different fileformats?

public enum FileFormat

FileFormat fileformat = GetFormat();
switch (fileFormat)
case ...

 If add an item to the enum definition in this case I have to change all the code that uses switches and that kind og enum which, I guess, is a bad approach in terms on maintenance of the application?

ListView DataPager with SQL-Statements that already return only paged data.



As far as I understand the ListView-Control and the DataPager-Control, they work like this: The ListView gets its datarows from its data source, then the DataPager causes the ListView to display only a subset of those rows.

So what, when I want to use custom databinding for the ListView, that *already* gets the certain subset from SQL-Server (for better performance). Can I and how can I use the DataPager then?

Thanx, S.

VS 2010 HTML validation "in CSS" option - where the hell is it?


In VS 2008 there is a very useful feature of background HTML validation - it checks if CSS class name is valid i.e. it exists in one of the linked css files. But VS 2010 Express does not do that any more. And the relevant setting in Options->Text Editor->HTML->Validation->in CSS is not there. Ok, maybe they made it paid for option? VS 2010 Professional? Not there. Or maybe VS 2010 Ultimate? Not a trace.

1. am I blind?

2. they decided it is too convenient to use and removed it?

3. they will "introduce" it in SP1?

What is going on? That one thing made me move back to VS 2008 web developer.

How to switch between HTTP and HTTPS in ASP.NET MVC2


ASP.NET MVC2 has the new RequireHttpsAttribute that you can use to decorate any action to force any non-secure request to come through HTTPS (SSL).  It can be used as simply as this:

        public ActionResult LogOn()

Now any request to the LogOn action that is not over HTTPS will automatically be redirected back to itself over HTTPS.  This is very useful and easy to implement.

Unfortunately though, once the scheme is changed to HTTPS, all following requests will also be under HTTPS, which is not necessarily what you want.  In most cases you do not need all requests to your site to be secure but only certain ones such as the logon page or pages that accept credit card information. 

To handle this you can override the Controller.OnAuthorization method.  From within this method, you can check to see if the RequireHttps attribute is set on the Controller Action by searching the Attributes collection of the ActionDescriptor object. If the RequireHttpsAttribute is not set AND the request is under SSL, then return a redirect result to the HTTP (no

Attach Workflow to Task List, don't get option to manually start workflow via dropdown on task item



I am running WSS 3.0 with other workflows which are functioning correctly.  I created a new workflow in Visual Studio 2008 and was able to successfully run it in my dev environment.  I attached the workflow to a task list in my dev environment and was able to manually start the workflow by using the drop down workflow option and using the menus to manually start it.  I installed this workflow in our production environment and attached it to the task list (which had a SPD workflow attached to it which stopped working about a month ago).  I made sure that the option to manually start the workflow was checked.  When I tried to manually start the workflow, (hover mouse over title, drop down) there isn’t a workflow option.  The workflow also will not start automatically when a task is changed.


I attached this same workflow to a different task list in production and get the option to start it.


I have tried creating a small workflow in SPD 2007 and attaching it to the task list.  It shows that it is attached, when I look at the workflows that are attached to the task list, but I still don’t get the option to manually start it.


I have checked my security and I have fu

Switch views when opening a form depending on submit locations?



I would like to know it was possible to switch views when opening a form depending on where the form has been submitted.

I am submitting my form to library A and library B and want to be able to open it in view 1 in library A and in view 2 in library B.

Is there a way to set some url conditions in the open behavior rules?

Cannot switch between tabs of a tab control at design time

Drag and Drop data binding and Enums

I'm using Visual Studio 2010 to design a simple WPF application. I created a simple class, with some Enum property, and added the class as a new data source, then dragged and dropped it from the Data sources window as a DataGrid. The result is a data grid that works properly, except for enum handling. Obviously, I want enums to be displayed as combo boxes, so I set the option. The problem is: I get a combo box column, but it is NOT populated with the Enum's values, instead only the current value is displayed and the user can't change it. This behavior seems completely useless to me. Am I doing something wrong here, or is there another explanation for this? Why isn't the designer handling enums in a sensible way? Another problem is, if I choose to drag the class as "Details". Again everything works except enums. I get a standalone combobox, but it displays the values of the property from the entire list, and choosing a different item in the combobox changes the active bound property. Once again, useless behavior - I expect the designer to create a combobox populated with values from the Enum, and for it to act like every other control in a master-details relationship - choosing a different value changes the state of the current item. Please advise.

Multiline Option does not work

Hi,Below is the sample piece of code(The code is in VB.NET), where I am expecting an answer of "true" with my basic knowledge of Regular Expressions.---------------------------------------------------'VB   Dim r As New Regex("^def$", RegexOptions.Multiline)   Dim d As String = String.Format("{0}{1}{2}{3}{4}{5}", "abc", System.Environment.NewLine, "def", System.Environment.NewLine, "def", System.Environment.NewLine) MsgBox(r.Match(d).Success)-----------------------------------------------------------The answer I get is false, but there are two "def" in 2nd  and 3rd line of the data and Multiline option is enabled, I have checked it with VS 2005 and VS 2008, both give me answer as false.  What is the mistake I have done? Please help.Thanks and Best Regards,Bennz Benz
