I have a project I'm working on in ASP.NET but I'm having problem in the coding of my loging page.I have UserId and Password in my loging page.If the user iput his UserId and Password in the loging page on click of the OK BUTTON then, the login page should compare it with UserId and Password in the Database. if it matches then it should take u to the nextpage but if not he should Throw an Error message INVALID LOGIN. This Is just a normal User Login in ASP.NET .Thanks
All I want to do is just like the way we login here as a user.If u input wrong userId and password u will not be able to login but if your userId and password
are correct then u will be login as a user.I will be using SQLSERVER2000 as my batabase.Hope u now understand.Thanks for ur responds
All I need is just the code for login.I have created my table in the database and the fields are UserId And Password.Also I have created my form and my textbox are UserId,Password and OK Button.Now I want to login from my form using a specified username and Password that will be verify in the databese.If the userId and the Password is not match with that of the record in the DataBase then it should throw an Error message Invalid Login if It matches it should go to the next page or specified page in the programme.I'm using SQLSERVER2000 as my Database.This program is ASP.NET program.Thanks for the responds
build a SQL statment that select count( UserId )where UserId=the input userId and Password=inputPassword
using Ado.net connect on DB And Retrive Data if the statment returned 1 then set a session with value =1 and check on this session along the flow
It's a good practice to release the resources back to the system, however if you want it immediately, then i'm afraid you cannot. To some extend, you may use the Collect method of the GC[^] class to force the garbage collection. You can read more about this in the documentation Garbage Collection [^]
Iam trying to assign values to web date chooser control inside update panel but when the update panel postback it throws win32 exception .
I wants to assign values to webdatechooser control without the whole page getting postback.
Can any one helps me to go further ?
Since you mentioned an UpdatePanel I'll assume you're refering to Atlas in ASP.NET 2.0. If that is the case I would first suggest contacting infragistics (whose support is ok) and see if they have got this same type of thing working.
While you wait for their reply you could always make a simple test page with just the webdatechooser and an update panel to see if you can get the page to work with just those controls.
This is a bit of a complex one, appologies in advance if this post ends up being long.
I am creating a dynamic questionnaire system, which is data driven, is split across pages and has 4 different types of question (SingleSelect, MultiSelect, SingleLineTex, MultiLinetext) each created as a UserControl. Each page of the questionnaire can have multiple groups of questions (called a QuestionGroup), and each question group can have multiple Questions.
The problem im facing, in brief, is that when the page is posted back the data for the questions within a group is no longer available. Im tearing my hair out with this, as winforms dev is my normal thing and not knowing how to do something in web development is mighty frustrating!!
Ill try to be more detailed. I have a web user control called QuestionGroupControl, roughly defined as follows:
QuestionGroupPanel is where I dynamically populate each question within that group (this can be one of 4 controls as defined above). Here is the code im using in the code behind of the QuestionGroupControl:
I, of course, assign my QuestionGroup datatable as the datasource for the repeater on the page.
The error I get is within the OnLoad override in the QuestionGroupControl - it says (quite rightly) that on this line: foreach(QuestionnaireDataset.QuestionRow question in this.QuestionGroup.GetQuestionRows())
that this.QuestionGroup is null.
Im 99% sure its the order in which im building the controls up, has anyone got ANY pointers for me?
Um, this might be a bit simplistic and i'm not understanding, but how are you persisting your questionGroup variable across postbacks. Unlike winforms, the questionGroup variable that you wrap with the public property will not automatically be persisted.
Also, and this is just nit-pickery, but public properties on aspx pages is not particularly good practice - particularly with the new 2005 project structure.
(BTW, seeing the current blacklist makes me really want to try and get on it... It's like an itch that i really shouldn't scratch...
Thanks for the reply... I should have added that this is .NET 1.1 not 2.0
I am not persisting the questionGroup variable, and I think this is at least part of the issue. I tried storing it in ViewState originally but I get an error saying that an object of that type needs to be marked as serializable or have a type converter defined...as the code (for a typed dataset) is autogen'd I cant add either of these!
As for the nit-picky-ness that property was supposed to be protected, and is there for syntactic sugar - its not part of any real functionality.
As for the blacklist, feel free to be rude, abusive or insulting and you'll be added in a second The downside is that I answer about 100x more questions here than I ask. (in fact this is the first time I ever remember asking a question and I have about 800 posts!) A position on the list ensures I never answer your questions!
That's going to cause you problems - you'll need to either store the dataset somewhere or rebuild it on every postback. I've never worked much with typed datasets, so i don't know about marking it serializable, but it's kinda funny, as an ordinary DS is serializable by default...
Is Ajax the only way to go? I'd rather not have to create pages to process the data if possible, I just want to persist the changes!
