View 3 RepliesI need to know what would be the best choice of array to use given the following specifications. This array's size will be predermined upon the loading of the appication. All I want to do is be able to add values to this array and replace preexisting array items with new values without the array changing size. Someone suggested that I use a Dictionary Array Object? I would appreciate any suggestions.

View 7 Repliesmy JSON is as follows :

Now i want to filter out only array from that JSON and store them in a variable like this :

I have a few applications/websites running with LINQ to SQL and the other day I decided to go ahead and optimize some of the queries, etc and I found that the size for variable length data types is derived from the parameter value instead of the column actual size? for example a column is defined as nvarchar(30). when I use linq to query that column with a value that's 5 characters long the parameter in sp_executesql will be defined as nvarchar(5)...this causes a major procedure cache bloat even for a small utility site that has a lot of queries is there a way to optimize this?

I have an storedprocedure which checks the following scenario:
An email will be sent to multiple customers simulataenously. the email addresses are seperated by semi colon. I have to save that mail in a table and then in the same procedure, I have to check each email address and whether it is of any customer in the customer table.. If it is of customer, then i have to insert an entry in another notes table. For this i am doing the following operation in Stored procedure:
[Code]....
the above is the part of storedprocedure i wrote. The problem is I get an error when executing this stroed procedure in Asp.net
Could not allocate space for object 'dbo.tbl_Notes'.'PK_tbl_Notes' in database 'ProjDB' because the 'PRIMARY' filegroup is full. Create disk space by deleting unneeded files, dropping objects in the filegroup, adding additional files to the filegroup, or setting autogrowth on for existing files in the filegroup. and following that code, i am executing another SqlBulkCopy operation in front-end .. that returns the following error:
System.Data.SqlClient.SqlException: Could not allocate a new page for database 'ProjDB' because of insufficient disk space in filegroup 'PRIMARY'. Create the necessary space by dropping objects in the filegroup, adding additional files to the filegroup, or setting autogrowth on for existing files in the filegroup.
iam using function overloading in a class,my doubts is that, if,for exampleaddmax(int j),addmax(intj,intk).it allocate two memory space or only one.

View 4 RepliesIn my program, I need update a filed to the database. The field is for a pdf file content. I know, maybe I should save the pdf file to the local file system, and save the file path to the SQL. but, right now, it is the file content saved to the SQL.
from my program, it loads the file which is input by user. I use File.ReadAllBytes. Then, run the stored procedure on the SQL server, and use the bytes[] as parameter, to insert the file to the SQL. it works fine when file size is small. However, as file size becomes larger, say 200MB, sometimes, it pops out of memory exception.
So, I'm thinking, maybe I can load parts of the file, say 1MB a time, then update the database, then loop. so, this way, no matter how large the file is, it should not have any problem.
my question is: is there a standard way to do this? so, I should not save file content to the SQL at all? shoudl save file in file system, save the file path to sql only? or there are other way to deal with this?

View 2 RepliesJust wondering if anyone has any idea how you can determine how many bytes of a request have been read/received by the server... In other words how do I stream http request...
In that, users are uploading files and I want to report on a perotic basis how many bytes have been read/received so far.
I have a bytes of data. Eg : 1024 bytes. And in that, say "Name Age Occupation" etc. All are only values. I have another skeleton xml which will have the <Name/><Age/> etc.
I need to loop through the bytes, say first 5 bytes is Name, Next 2 bytes is Age etc and fill up in this XML. I'll have 1000s of records and so need to know which way is the fastest.
Will the code be fastest or is there any way i can do by XSLT or similar component?
I need to find a way to accurately calculate the byte size of the text inside a particular textarea. I am working in .Net so I have access to those libraries, but I'd prefer a Javascript solution. How many bytes is each character worth? What would be the most efficient way to count and multiply? Or am I missing a better way entirely?
Edit: I'm attempting to determine the download size of a piece of Javascript that has been pasted into a textarea. The closest thing I could find to this is ][URL]. I don't want to just lift their code, especially since I don't fully understand it.
