ADO.NET :: DataSet Cleanup Necessary Or Partial Class Handle All
Aug 25, 2010
I've looked around and I can't seem to find a good answer on this. Is there any cleanup needed on a strongly typed dataSet? I'm using DataSets as my DAL but I don't really have a BLL. I'm handling this in my code behind like this:
[Code]....
I'm assuming it handles the opening and closing of the connetion? The adapter has a dispose method. Should I be using this? Is there any cleanup necessary or does the partial class (that inherits system.data.dataset) handle all of this?
I first need to apologize in case this has been answered before but I'm a newbie (green as they come) and this error keeps popping up even before I start debugging! There are two errors and the second one is:" Error 2
Missing partial modifier on declaration of type 'WFPKenya2.WFPKenya2'; another partial declaration of this type exists"
I have to know how to achieve the following senario in an web application,I have a search functionality, where i will give some parameteres which are used as input to my select query in sql database.
Once i click the start search button the parameters will go to database and execute the query. and display the result in application.If i click the Stop Search, i want to retireve the records which are available till that time. How can this be achieved in .net
After wading through quite a few articles on creating modal forms (using partial views and jquery) I got things working fine for my login....as long as you enter a valid login though!
What I did:
Created a partial view containing my login form.
In my action controller, the get action just return a PartialViewResult, which get dealt with by a bit of jQuery in my master:[Code]....
Like I said this works fine. Now the post action of my login check if it's a valid login, and if so send the user to the passed returnurl or the home page.
However, if the validation fails, I now return the partial view again, which work , but the partial get displayed by itself instead of rendering in the modal form that was opened by jquery.
I am maintaining and old application in ASP.Net and it has one CustomGridView control with 4000 lines of code. I see that in that file only, when I try to modify any code the IDE does not respond quickly as it does for other files. I thought of creating partial classes for the same but it seems that VS is not reconginzing the new partial class. I am trying to use the variables from the old partial class and it is not able to reconize any variable or method.
I have 2 projects. A data project, which contains my database and my Entity Framework model. I have table called 'User', and then have a generated EF class for user. I am trying to add a partial class:
using System; using System.Collections.Generic; using System.Data.Linq; using System.Linq; using System.Text; namespace Data { public partial class user { public bool isValid { get { return (GetRuleViolations().Count()==0); } } public IEnumerable<RuleViolation> GetRuleViolations() { yield break; } partialvoid OnValidate(ChangeAction action) { if (isValid) throw new ApplicationException("Rule violation prevents saving"); } } public class RuleViolation { public string ErrorMessage { get; private set; } public string PropertyName { get; private set; } public RuleViolation (string errorMessage) { ErrorMessage = errorMessage; } public RuleViolation(string errorMessage, string propertyName) { ErrorMessage = errorMessage; PropertyName = propertyName; } } }
This is following the MVC 1.0 NerdDinner example. However, I am getting a design time error on the OnValidate method:
partial void OnValidate(ChangeAction action) { if (isValid) throw new ApplicationException("Rule violation prevents saving"); }
No definining declaration found for implimenting declaration of partial method 'void OnValidate(ChangeAction action)' What am I doing wrong?
I have a table of people with columns holding bits of info about them. I also need a variety of computed columns such as FileAs (lastname + ", " + firstname) and CityStateZip (you get the idea). I am wondering where best to put these definitions. It's worthwhile to note that the user will want to search for things as seen on the page, not the little atoms in the table. For example, searching on ", e" finds everyone whose first name begins with E. Typing ", az" to get everyone who lives in Arizona.
I noticed that linq-to-sql queries only recognize the fields in the table definitions, not any that are added in the partial class associated with the dbml. Linq-to-sql does work against computed columns in the database; however, the column definitions--especially for international address formats--will become very complex and much better handled in code.
got a question regarding form validation via entity partial class. I created my edmx-file with the Entity Data Model. Now I am trying to validate my form inputs via this partial class:
[Code]....
Edmx file and partial class are in the same namespace. But the partial class does not get fired. My controller file looks like that:
I created a file cleanup function by using health monitoring. It is deleting file that is no access from another process. So, I want to check this. Is it stay access. If not access, I delete this file. How can I do?
I am tasked with customizing a third-party web application. Since the application is updated (ie new files are copied over the existing files) several times a year, I was hoping that I could put my custom code in separate files -- sort of like having asecond code-behind file for each page that is modified.
I have a website that i converted from asp .net 1.1 to 2.0 and now i have one page that said ambiguous reference because in 1.1.all controls needed to be defined in the class as well. Well after deleting those and leaving only the declares in the Markup,it says that the variables do not exists in current context. Intellisense allows me to use and reference them from the page but when trying to build it leaves me with that error.
I requirement is my code Behind file contains more than 5 thousand line, Now i want to split the code into two file ...The other file also accept the web controls eventsi tried with partial classThis is my Code Behind File
because of i want to use some cods in difrent projects i create a class library and i write my codes there but i don't have access to my controls event in this example i try to check something befor the user login to website and if there is an error show the user a clear error message
[Code]....
in this case because of my codes are in class library the event for MainLogin.LoggingIn doesn't work and it return an error that it doesn't understand the MainLogin.LoggingIn event.
I have added a partial class to one generated by the Entity Framework. I wanted to add a calculated field that I could bind to my GridView. However, when I try to access the new property, I get an error message that this is a limitation to Entity Framework.Are there any work arounds to accomplish this?
We're having a problem in our ASP.Net application where the Crystal Reports engine leaves garbage .tmp files in the server's Temp folder after generating reports for the users.So we're trying to figure out how to run the .Close() and .Dispose() methods on the Report object, but we're finding that the code never gets run after the export occurs.
Breakpoints set on the last two lines never get hit, and we've also tried putting other code there to test the processing. None of it runs. (I've also seen this question on other sites with similar code, but no answers)I assume the ExportToHttpResponse method is returning a file stream (PDF) to the user at that point, ending the processing so the rest of the code doesn't get run. If that's the case, how do we get CR to perform a cleanup on the temp files, which the Close() and Dispose() methods are supposed to do? Do we have to implement a manual after-the-fact cleanup?
