Best Way To Store And Retrieve Boolean Value?
Jan 5, 2011
I am writing a bit of code to store about 100 (yes/no) answers about hotels. I have about 7000 records so I need to try and get this right the first time.At the min I have 4 * int32 values stored in SQL and I use a structure containing names boolean values like swimming pool, bar etc etc. In my BLL I have a method that tests the bits in the int 32 and sets the boolean value to try or false.
I have not had any problems with this way, but was thinking about the performance as this would currently have with about 100 if statements in the BLL to set all of the boolean values.The only other ways as I see it are..
1) have 100 boolean columns in the sql table, which I feel would be messy.
2) to have all the int32 sql values populate another text field that is stored in the DB so that the int32 value creates a text string when the hotel owner populates the click boxs in the first place. - then I just display the text value which would have been created something like "pool, bar" My way of lots of ifs does work, I was just worried about the performance

It should store plain HTML fragments of a page like the standard Output cache in asp.net .The HTML may contain dynamic content from a database.When an object is updated in the database all the cached HTML fragment containing that particular object should be destroyed and re-cached next time it will be requested.
There is a separate admin tool to handle all data in the database so I can easy store the Id's in a cachetable when an object is invalid. I can also make a request to a page that destroy all cached HTML fragment for that object.
But when I write the markup, how could I do to store and retrieve a particular segment from the cache? Of cause I could do this in code behind and have the markup in a string but I don't want that. I want to have the markup as intact as possible.

SQL TablesListingID, Title.....ListngTypeID,NameListingMatrixListingID, ListingTypeID
Basically a listing can be more than 1 type and I want that to be able to be shown using the ListingMatrix table. However, I'm having a lot of issues populating the checkboxlist because I have it being sorted by Title to keep it user friendly. I'm using VB.Net, LINQ and MS SQL.
Dim readListingMatrix = (From ListingCategories In db.ListingTypeMatrixes _
Where ListingCategories.ListingID = ListingID)
For Each row In readListingMatrix
CheckBoxListListingCategories.Items(row.ListingTypeID - 1).Selected = True

I am using C#. I am consuming a webservice. The webservice has a method, which has the return type as blob. The webservice serializes the data before sending as blob.I am able to access the webservice method, but I am not sure how to store the value, as the return type is a blob.I have tried this:
Service1.TestService serv = new Service1.TestService();
? = serv.Custom_methodname(true);
How to assign the output as it is a blob variable?

I am working on a project (asp.net web application) that takes files from users, stores them and retrieves or shows them back to the user when needed. I am saving files on my file system (drive). When I save images and refer to them in iframes, images are being displayed in iframes. But when I save .html file and refer it in an iframe it is not displaying the html file. I want to store a .html file on my file system using file upload and store on my local drive, display it in an iframe.

I need a place to store images. My first thought was to use the database, but many seems to recommend using the filesystem. This seems to fit my case, but how do I implement it?
The filenames need to be unique, how to do that. Should I use a guid?
How to retrieve the files, should I go directly to the database using the filename, make a aspx page and passing either filename or primary key as a querystring and then read the file.
What about client side caching, is that enabled when using a page like image.aspx?id=123 ?
How do I delete the files, when the associated record is deleted?

I have a public property that I use to store a GUID in the viewState:
Property myGUID()
As
Guid
Get
Return
CType(Me.ViewState("myGUID"),
Guid)
End
Get
Set(ByVal
value As
Guid)
Me.ViewState("myGUID")
= value
End
Set
End
Property
I include this code on many pages in my website...is there any way to migrate this to a common code file, so I don't have to repeat it on each page? If I try to add it to a class file, the "Me" part of course is out of scope.

My problem is regarding title written above. Currently I have some functions that rely on Sessions to do the job. Everything works smoothly when it is left to default. However, I do not like the idea of losing sessions in case of crash and I have modified my web.config to use Sql Server mode instead.
I have run the necessary commands to create tables and stored procedures in my database using aspnet_sql.exe. I am able to store values into the database but have not been successful retrieving them. Since it has been working fine with InProc mode, I think I can safely assume that there's nothing wrong with my codes. Here's my web.config setting:
<sessionState mode="SQLServer" allowCustomSqlDatabase="true" cookieless="false" timeout="120" sqlCommandTimeout="30" compressionEnabled="true"
sqlConnectionString="Data Source=.SQLExpress;Initial Catalog=mytest;Persist Security Info=True;User ID=mytest;Password=mytest;"/>

Actually what i am doing in my Data Access Layer dragging store procedure to TestDbml to display records and creating data context instance in BAL to retrieve records and my method in BAL is like this
public IEnumerable display()
{
using (TestDataContext db = new TestDataContext())
{
var display = obj.USP_Actor_View_Speciality(p_UserName, 1);
return display as IEnumerable;
}
Now the problem is that how can i iterate or fetch over the records and display accordingly in my Presentation Layer so that i could return all the field parameteres Like ield1=val.field1,field2=val.field2.

I have been asked to develop an ASP.Net application which will directly connect (store and retrieve) to the ACT! databse already functional. I am new to ACT and looking for a starting point to integrate it with ASP.Net application. In particular I am looking for answers to the following questions:1. What database technology is used by ACT? Is SQL Server? In that case, I should be able to connect just like any SQL Server database?2. Is there any class library or API for .Net from ACT which will help achieve this?3.
