Does putting multiple classes in one file impact performance? Has anyone had any experience with this.
I've read various discussions around application structure and logic of where code can be found with regard to design best practice but little has been said as whether there is any negative/positive/neutral impact on performance.
I would like to know the performance impact of using the culture invariant resources instead of culture specific ones.
For example, we plan to deploy a website and not have any en-US resources. This is because our culture invariant resources are always identical to the en-US resources.
When adding a new page or user control to an ASP.NET webforms application, the code-behind class contains an empty Page_Load() event handler:
public partial class Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
}
I have an existing web app, where many pages and controls still contain these empty event handlers (they are not used).
Question: Is there any performance impact due to these empty event handlers and should they therefore be removed from all pages and controls?
In my website I am using thread to perform the function which downloads the CSV from a website and parses the data into the database.
Now if I am not able to stop the thread then what could be the impact on the performance?
Also If I unknowingly start another thread then would it impact my website's performance?
I tried to find out about subject but with no success. The point is that in the beginning I've made many user controls. My site is too slow. I have not idea yet if it is because of user controls.
View 7 RepliesNot sure this is the right forum for this question, but... So in my web apps I have many BLL classes that connect to some TableAdapters/DataTables for data management with the database. I read somewhere long ago that before the project is deployed for live usage, it's a good idea to turn the class files into DLL's, because some performance gain could be achieved. Has anybody ever really tested out this concept?
If my understanding is correct that the whole app gets turned into a DLL anyway the first time it is accessed, is it only the first time the web page is accessed that this might make a difference?
So far i've populated my grid view with my roomID. however using data reader I don't seem to be able to get more than one column to auto generate even though i'm now looking for three values : SELECT tt_roomEquip.roomID, tt_room.roomCapacity, tt_equip.equipTitle is my select bit of the sql, though it's only putting roomID into my grid view.
View 1 RepliesWhat is the impact if I leave the "compilation = true" in the web config file when I publish an application? Will it affect performance or have some other impact?
View 3 RepliesI am creating a web service in asp.net. I not getting which one is better way to manage multiple classes with web service.
Two way in my mind but i am not getting which one is better.
1) Call all classes in single .asmx file.
2) Create different .asmx file for all classes.
paypal.sandbox.AddressType addressType = new paypal.sandbox.AddressType();
addressType.AddressID = "Your Address ID";
paypal.sandbox.DoDirectPaymentResponseType response = new paypal.sandbox.DoDirectPaymentResponseType();
response.TransactionID = "25554d";
I want to call my classeslike this from my code behind. I am not getting this how can i call like this.
I am used to making separate Business Object and List<> classes for my DB tables. Sometimes I just have a basic task in hand as displaying a list of year for a search box or having some values in a drop down.
Right now I am ending up with a lot of separate classes and List classes<> for these basic operations.
How can I make a single class for some basic tasks as these by using generics? I want to have single class for some methods like get current year, employee names, Department Name/Code, Title etc. I am using .NET 2.0.
Edit
After some searching, I found that I can achieve similar tasks by creating a DTO namespace.
What I don't get right now is how to create multiple classes inside my DTO class. Say 1 class for just returning 'year', One for 'Employee Name/Code' and so on inside the single DTO class.
I would like to display students and their grades with a GridView and LinqToSQL like this:
assignment1 assignment2
Student 1 55 89
Student 2 87 56
Student 3 92 34
I have a many-to-many relationship between students and assignments called "grades". The grade for the assignment is stored in that table in a "gradeNumber" column.
I would also like to specify which assignments should be displayed in the grid. Btw, my LINQ entities are extended to allow me to write/get studentx.Assignments or assignmentx.Students.

Is it possible to create a table class that can be used for multiple tables? For example, if I have some class:
[Code]....
In LINQ to SQL, this maps to a table with a name based on the class name, DBClass. However, suppose I want to use that class for multiple tables, and it could be an arbitrary number of tables. Is this possible
I would like to reuse in different ASP.net classes the following code :

However i cannot add this code in App_Code because Session is not recognized in .cs classes.
Therefore i need to create resusable asp.net classes which will contain the previous code.
I am currently extending the NopCommerce solution for a client and have some general questions about workflow, since this is a relatively large solution for me (50+ projects).
I want to add some classes to the DAL, BLL, and so forth.
What would be the recommended process for this workflow? For example, I created a class in the DAL -> ran build. Then I created a test.aspx page in the main project which instantiates this class -> ran build; however, adding just one line of code causes the solution to rebuild all other projects such as payment modules, which makes the process tedious.
Am I approaching this in the correct manner? I have read about: creating a seperate solution with relevant projects; is this the recommended approach?
I came across the article few days ago where somebody said that it's possible to automatically break down ClassName.Designer.CS into multiple classes.
So instead of having Customer and Order class definitions in one .CS file I'm going to have 2 .CS files: Customer.Designer.CS and Order.Designer.CS
I have a dataset that comprises of multiple tables (about 20) linked together with constraints to reflect the relational database. My question(s):
1) Will having multiple tables affect performance? I'm asking this as there are often times I would not need to get data for all the tables, but only for specific tables.
2) If it does affect performance, would breaking up the tables into their own datasets be the best solution. It seems to me that by doing that, you would lose the ability to apply constraints among tables and tables that might exist in multiple datasets will be subjected to replication.
I would like to have everything in one dataset as I get a view of the related tables and their relationships and also because the Fill method allow me to fill tables, maintaining the hierarchy of the data, but performance is still a key factor.
I am new to LINQ. when we drag tables we get a dbml file and designer file.
For example DataClasses1.dbml and DataClasses1.designer.cs.
Once we have them then we can start using our LINQ Queries.
In my company project I do not see this designer files and instead there are .tt files which were used as templates to greate ABC.generated.cs files. Is this same as designer class?
I was wondering which of these two is better from the aspect of performance.
I was thinking that possibly Class files stored in App_Code works faster because they are sort of pre-compiled but i am not 100% sure.
Specifically i am overriding onInit event on each page using some functions that i am not certain where to place.
Not that i complaint on the speed but i want to be sure that i am doing the right thing.
I am following the Nerd Dinner tutorial as I'm learning ASP.NET MVC, and I am currently on Step 3: Building the Model. One part of this section discusses how to integrate validation and business rule logic with the model classes. All this makes perfect sense. However, in the case of this source code, the author only validates one class: Dinner.
What I am wondering is, say I have multiple classes that need validation (Dinner, Guest, etc). It doesn't seem smart to me to repeatedly write these two methods in the partial class:
[code]....
This doesn't "feel" right, but I wanted to check with SO to get opinions of individuals smarter than me on this. I also tested it out, and it seems that the partial keyword on the OnValidate method is causing problems (understandably so). This doesn't seem possible to fix (but I could very well be wrong).
I have developed a website in asp.net framework 2 . This website is being hosted in two different servers without any change in code. My issue is about the performance of these 2 sites. One website is taking much time for inserting datas to the DB (SQL server 2005). 2 websites are having different DB server.
I think the issue is for the DB server. How can we rectify the DB performance while insertion and Is there any other cause for this permance issue?
Is there any software for the same? I didn't find any useful information on the internet so asking here.

I don't know if this has to do with how FindControl works or how scope works. But my base class is having a hard time seeing the fields of child classes. Currently I'm planning have the derived class set a property in the base class, but there are a lot of derived classes, so that isn't a very attractive solution.
