I have a quick Linq to SQL question. I am trying to write a Linq query that has multiple where clauses depening on user input. What I would intuitively code is:
Dim arrTerms As Array = txtUserInput.Text.Split(" ")
Dim q = From newsitem In db.MyNewsTable _
Where newsitem.Contains(arrTerms) _
Select newsitem
Listview1.DataSource = q
Listview1.Databind()
Unfortunately, though, the "Contains" operattor does not accept an arraylist, or array, or anything but String.
I'm trying to setup some simple custom HTTP handlers which will render an aspx page to a string builder and then write the result to the HTTPResponse. My problem is that when I call base.Render(writer), the rendered page isn't written. Here is my code:
FROM THE HTTP HANDLER CLASS
public void ProcessRequest(System.Web.HttpContext ctx)
{
Home h = new Home(); //This is an instance of the ASPX Page I'm trying to render
StringBuilder sb = new StringBuilder();
System.IO.StringWriter sw = new System.IO.StringWriter(sb);
[Code]....
Everything is working as it should, when I debug it executes the proper methods and does not throw errors. I can use hw.Write("STRING") in the HTTP handler to write text to the Response which displays on the screen fine. Also, the aspx page itself renders fine when I don't use a custom handler, so there is no problem there. The base.Render just doesn't seem to want to render the page's contents. I've tried RenderControl as well, and the same thing happens. From Googling around, this should work.
I have to implement User base security in my Web project using .Net3.5. Followings are some we need:
Roles can be Admin, Manage, Editor, Member etc User can have multiple roles Every roles has its own dynamic menus and restrictions/resources All menus and interface will populate dynamically from Database
I heard some where this kind of i.e user base security can be implemented using HashTable but I dont know how is it?
Today I came to know that for this kind of work Java people use Interceptor Design patterns. So, how could I do the same in asp.net C#?
How can I show a saved picturs from data base into a Image control? And how can I save an Image from my web page into data base?
View 10 RepliesI have a CMS page that allows the user to paste in or type HTML code into a TextBox in a FormView, then do an INSERT or UPDATE operation to an nvarchar(MAX) column in an SQL table. This is using an ObjectDataSource that refers to an insert or update method in a TableAdapter in my dataset.
When testing, the server initially warned me when I tried to input or update text containing HTML code; so I set the validateRequest="false" in my page header.
I gather this can be a serious security risk. What's the proper way to "validate" the string being input? Am I opening the database to SQL injection?
Only the site administrator has access to the CMS, but malicious could theoretically bust their way in...

View 3 RepliesI simply want to know how to manually check if the value a user has provided for the answer to their security question matches their current answer on record. I want to use the build in support of the ASP.Net membership and membershipuser objects.
I see that via the passwordrecovery control that the actual answer can be returned. However I am currently not using this control and it would take a good bit to integrate it as it does not meet our user's requirements.
In a worst case scenario, getting the actual answer (like the passwordrecovery control does) and manually checking it in our application would be acceptable.
A best case scenario is some sort of API where I can pass in the user name and the answer to their security question that was provided and simply get an indication of whether answer was correct or not.
I am using jquery.fancybox-1.2.1.js of fancy box in asp.net applicationQ1: In the base page i have datagrid and on combobox. on slection of combobox the datagrid is populated.From the datagrid I open the fancybox when user click on Edit link.

I'm looking for a way to have user upload as many images as they want (perhaps via drag and drop) or dynamically adding more upload box.I thought statically fixing (say 6) HTML upload input box is slightly limiting and the user have to click "Browse" button (6 times in this example) and navigating to the folder to pick the file.What is the best practice to achieve this so users find it easy to use? Perhaps with some AJAX magic?I also wouldn't mind having the user click "Upload more" to reveal (say 6 more) HTML upload input box.
View 2 RepliesI am using HTML Input control that will open a file dialog window where user can select a file.
Is there a way to set a path from where to open the window. Right now it looks like the default folder is "My Documents".

I would like to program an Input Box that comes up when a user clicks 'Find' button. It asks 'Please enter an employee number'. Then it takes the employee number typed into a text box and searches a dataset for that specific employee record.
I know that it should be server side because the client may not have the proper javascript installed or diabled. Therefore, can someone give me some code to put in code behind that can pop up an input box and use the input after, if this can be done?
I have a quite complex model which has an image as a part of it. While uploding the image i get the following error "The input is not a valid Base-64 string as it contains a non-base 64 character, more than two padding characters, or a non-white space character among the padding characters"

I have an ASP.NET MVC web application running in IIS as a subweb; let's say its path is something like http://mysite.com/subweb.
I have a view which serves content obtained from a CMS. The CMS editor has entered some content containing a relative image path <img src="/images/imga.png" />.
This works fine on the production server where the site is the root website, but not on the staging server where the site is a virtual directory under the root website
The path should be <img src="/images/imga.png" /> on the production server
and <img src="/subweb/images/imga.png" /> on the staging server.
Is it possible to use the <base> tag to resolve this image path?
<head>
<base href="http://mysite.com/subweb/" />
</head>
<html>
<body>
<img src="/images/imga.png" />
</body>
</html>
It doesn't seem to work. Can anyone explain why or if this is a workable approach? I don't want to require the content editor to have knowledge of the website deployment option (which changes between UAT and production).

I've got a requirement to add a feature that will save off a dynamically created asp.net page so it can be recalled and reviewed at a later date. I was thinking of just adding a 'Save' button to the page and in the code-behind using VB to write the output HTML to a varchar(MAX) field in my database.Does anyone know how (in VB) to grab the entire page HTML so it can be inserted into a database?
View 6 RepliesI don't think I understand fully how ASP.NET does inheritance of controls.I have a user control, ucBase, which has an asp.net label in the ascx file. Code behind references the label and it works fine during run time if the control is not a parent for another user parent.
If I have another user control, ucChild, inheriting from ucBase, the label in ucBase's code is always null. ucChild has no controls in its ascx fileThe server controls (like the label) needs to be declared in the ascx file and not created programmatically.What needs to be done for ucBase to see its own controls when it's a parent user control?

I have an html input control that is a radio button. This radio button needs to disable required field validators when selected. This is my non working code so far. What have I not done?
<input ID="card1" runat="server" type="radio"/>Card<br />
btnSubmit_Click
{
if (card1.Checked == true)
{
RequiredFieldValidator10.Enabled= false;
}
}
this however doesnt disable the control.
I have a GridView control that has an ItemTemplate that contains an HTML radio button. In my code behind I am querying a database, retrieving a column of values, and then binding the list to the GridView. My problem is that the radio button that I select is not being persisted on post back. I have tried using an ASP RadioButton rather than an HTML control, but when I do that all of the radio button can be selected at the same time (i.e. like check boxes). how to persist the radio button that is selected in this scenario?
[Code]....
