I am working on building a custom form builder module for our customers ... and wondering if you know any good .NET code base references for this module.
Requirements:
Customer should be able to add a form field(radio button, text box, dropdown menu) and customize the values real time.
how best to allow a user to create their own URL? Say I have a domain like, www.mydomain.com, and I want the user to be able to create a custom ending to the URL like www.mydomain.com/companyname . Then when the URL is hit it will load the data for that company. Is this done via ASP.NET MVC routing? Any other ideas? I don't want to have to do any manual setup of site after user names it - like IIS changes or routing config file changes.

View 7 RepliesI am learning VB.Net, what I would like to know is if I have a Button in Form1.aspx how can I create or use its click event in another module say Separate. vb.If I directly reference with the normal code in Separate.vb I receive an error "handles clause requires a WithEvents variable defined in the containing type". Or can I send a notification of the event to trigger a module in another Separate.vb ?

Basic measures when building forms that interact with the sql database. What are the security measures (check insert strings, sql injection etc), and Do people use special controllers in order to format their data? I am using GridView and realizing its tables, which I dont like. If so are there any suggestions for data formatting controllers?

I have an idea of how to do what I have in mind, but I would prefer to ask for some advice just in case anyone can think of a better way.The idea is a simple application where administrators can upload any kind of file. Once the file is uploaded, they give out a username and password to a client, and the client will then access a private area where they will be able to view specific files available for them. ALL THIS IS DONE. My question is... because the browsers can process certain type of files (for instance a JPG or a PDF), they won't automatically prompt the client to save it on their computer, and they will open int he browser. I have solved this issue before by adding a few lines of code to the Response and modifying the content type, something like: Response.Clear(); Response.AddHeader("content-disposition", "attachment;filename=logo_large.gif"); Response.ContentType = "image/GIF"; Response.WriteFile(Server.MapPath(@"~/logo_large.gif")); Response.End();However, that would mean I'd need to change the content type for each file (JPG... GIF... PDF ... WORD FILE). So I'd need to find out the content type for each one, and dinamically change it. This way it would force the download for all files. Now... is there an easier way? Remember that I need to have many different type of files, if it was only JPGs for instance, it would be easy.
View 2 Repliesexperienced pros on the best way of doing something.First let me give you the broad view of everything.I have a main site (http://www.ffinfo.com/) which is built completely in ASP.Net using C# 4 and has a SQL 2008 backend and then I have an CMS I am custom building to administer the site.At some point I hope to have more people playing the Final Fantasy games and helping me collect data to add to the site so I am using the CMS to both add/modify data in the SQL DB and genereate new pages on the main site as needed.I want to compile the main site so it runs faster as my server has limited resorces and after a reboot or upload of new pages it takes a little bit for the first visit to run.Now here is the problem.
When I use the CMS to make a new page I currently copy over a .asp and .aspx file from a template into the appropreate folder and am good but if I want to compile that page along with any other new pages made I have to scower my FTP for them, download to the local machine,build and publish.This will very quickly become a lot of work,not to mention I can not really take advantage of OOP.
So my question is this, how do I go about doing this better? Have I taken the wrong approce from the start and need to find another road or is the road I am ok I just need to improve my transportation?

View 3 RepliesI am writing a custom HTTP module to implement user authentication and appropriate access rights. And for identifying access rights for the user also depends on identifying the client's machine details like IP address, machine name, etc. The access rights will depend based on from which location or machine the user is trying to login.
Can we get these details from the HttpApplication or HttpContext object?

View 3 RepliesMy intention is to give the user a flexible user control on a master page that does the following:
When navigating, a child page will pass the URL (with querystring) and PageTitle to the user control. The user control will take those two parameters and insert them as a "breadcrumb" object at first index of a List<breadcrumb> collection
This part works fine through the use of a Repeater with a LinkButton contained in an ItemTemplate. The user sees each of the pages he has been visiting in descending order, the provided benefit is a quick way to re-open records they have recently modified or created.
The part I'm having trouble handling is what happens when the user clicks the LinkButton, which is that the child page adds a new reference to the URL at the beginning of the List<> collection and I cannot seem to control the behavior of removing the LinkButton before it gets re-created. What I've tried doing is:
List<>.RemoveAt(RepeaterCommandEventArgs.Item.ItemIndex);
Repeater1.Controls.Clear();
Repeater1.DataSource = List<>;
Repeater1.DataBind();
While that should work, my CreateBreadCrumb(string url, string title) function gets called by the child page before the UserControl detects the Repeater1_ItemCommand event, so in effect it appears that the wrong ItemIndex is being used for removal.
I am working in a school and we recently installed a new server running WinServer 2008R2. I want to be able to point people to a URL on our intranet and have them fill out a simple registration form and have this data written to a database. It would also be nice to have some data auto-populate (such as their name).
Is it overkill to set up a sharepoint server and try to do this with Access Webforms? Could I use something like dotnetnuke and find a module that works? Or how about options for writing custom forms?
What I'm trying to do is rather basic, but I might have my facts mixed up. I have a details page that has a custom class as it's Model. The custom class uses 2 custom objects with yet another custom object a property of one of the 2. The details page outputs a fair amount of information, but allows the user to post a comment. When the user clicks the post button, the page gets posted to a Details action that looks something like this:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Details(VideoDetailModel vidAndComment) { ....}
[Code]....
The only fields on the form that is posted are CommentText and VideoId. Here is what the VideoDetailModel looks like.
public class VideoDetailModel
{
public VideoDetailModel()
{
[Code]....
I suppose if I added more form fields for the properties I need, they would get posted, but I only need 1 form entry field for the CommentText. If I could get the same Model objects value that were sent to the page to post with the page, it looks like the solution is rather simple. I think using the RenderPartial in the middle of a form is problematic somehow to how the form gets written in html. I can't really put my finger on why things went bonkers, but if I do my RenderPartials before my form and then begin my form with the text entry field and the hidden VideoId, the default ModelBinder works just fine. I was beginning the form, writing the hidden VideoId, rendering several partial views, create my CommentText field, and then closed the form out. The CommentText field would get bound just fine. The hidden VideoId would not. Maybe I missed a rule somewhere about using RenderPartial.
For completeness, the partial view I was rendering took a Comment object and just wrote out it's CommentText data. Several of these objects would exist for a single Video object. All of this data was in a custom type and passed into the View (the main view) as it's Model. This partial view did not have a form and did not have any data entry fields.

View 1 RepliesI have a custom control which inherit from the Table class and in the constructor, it takes a an integer as an argument. There is no empty constructor.
Is there a way for the user to set that variable in the properties window after they drag the control onto a form.
I know some .NET controls, you can set the source for the parameter to different things like another control's property, QueryString using just the properties window.
Right now, I have to create the control dynamically. I read the query string and then created the object.

I need to write a stored procedure to schedule a job that will send automatic email to customers based on some condition as follows:
1. I have two tables. One table is table1 like the following:
Name Date1 Date2 Date3 Rahim, Khan 29'10 30'11 25'08 Karim,Abedin 12'10 28'11 26'09 Fahad, Alam 26'10 12'11 25'10 Another Table is table 2 like the following:
Name Email Rahim,Khan rahim@yahoo.com Karim,Abedin karim@yahoo.com Fahad, Alam falam@yahoo.com In table 1 the date format is in format where 30'11 mean work week is 30 and 11 means last two digits of the year.
2. Now , I need to write a stored procedure that will check :
a) What is current work week and current year?
b) It will then determine the difference between the current work week (now 37) and work week mentioned in date (Date1, Date2 and Date3) columns from table1 and if for current year(it's 2010) at least one difference in each row is>=8 then it should send an automatic email to the corresponding email address of Name column using the relation between Table1 and table2. For example: For first record in Table1 the three difference is: 37-29=8, 37-30=7 and 37-25=12. There are two differences >=8, but only first difference is for year 2010 and third one is not for current year. But, since at least one difference in this row satisfies condition (That means >=8 for year 2010)hence email message should be sent to the address rahim@yahoo.com using relation of table1 and table2.
I know how to set a schedule job in SQL mail but I need this stored procedure to run this job on daily basis.
