I am saving the file name list in the specified folder into the database. But my code should detect automatically if any new files have been added or any files have been deleted from the folder, then only the changed file names should again saved into db. I am not aware of the features of Folder properties.
View 1 RepliesI have a new VS2010 .NET 4.0 Web project and the Properties Folder has gone wierd on me. It has lost teh "Open" under the right click. There is no way to get a Settings file created now.

I am new to ASP.NET which is causing me a lot of problems in implementing my project. My project is to create a website for students to anonymously ask the prof. questions during the class. Basically I am able to create the website that maintains the list of questions. Now the main problem is "How to notify the Professor during class". The professor has a laptop connected to internet at all times. How can I send a notification message to the professor whenever a question is asked? I don't need a mail notification but I need to display a message in the task bar notification area.
View 2 RepliesI wonder what the right way is to set write permission on a Folder.I am in the properties for the folder I want to set write permissions to. The folder is named "Folder1"Now when I click the "SecurityTab", I can see a listbox there wich grayed out checkboxes for "Allow" and all of these are Checked, then to the right I have unchecked checkboxes for "Deny".I wonder if this is correct now, that "Folder1" has write permissions because this line execute that access is denied to "Folder1" ?

I'm struggling once again to get something centered on a page, and fighting with recalcitrant browsers. I can fix the problem for one browser by adding a style. I can fix it for the other browser by NOT adding the style. I can determine which browser I'm using. If I can change the properties of a div in the code behind, I can create a class and apply it to the div as needed. I added an id to the class:
<div id="alignLV2" runat="server">
but in the code behind, alignLV2 doesn't seem to have a class property. Is there a way to add a class or change the style?

I will try and be brief, I am finding when trying to create a custom route with a name and url of properties that my ASP.NET MVC app is returning a 404 file not found when hitting the route.I have deduced this down to most likely be caused by the fact I have a folder on disk called Properties which is of course a common asp.net folder which is automatically created. I have found someone else who has suffered from this problem on SO, but looks like there has been no resolution, only to name your route something different!
Surely this is an oversight, or there must be a workaround? Obviously there will be many common directories you may need as routes and/or folders interchangeably, some of which we already know like Properties probably can't be deleted! I also understand we need to honor real folders as URLs too, but I feel routing should take priority before looking at folders on disk.

I would like to know what is the best way to do a notification in asp.net.For example I have a form in which the user will provide some data. He then click the save button which call the save methode in my code behind.
In the save method I need to query the database to know if another related object exist. If not I need to notify the user that he will have to create the related object. This does not prevent the user from saving the parent object.
So I would like to do a modal popup telling the user : Hey after Im done saving your change, you will have to open another form and create the child object.So should I create another NotificationWebform where the user will be redirect after the sava to notify him. It seems to be a "lot" of effort for a little notification. The best thing for me would be something like an alert in javascript.
I am building a library of asp.net user controls which I am deriving from a custom UserControlBase class which further derives from actual UserControl class. Hierarchy looks like this :
ASCX -> UserControlBase : UserControl
I have this requirement to put a border around all the ASCX's. So, I thought if I can modify UserControlBase it will apply to all ASCXs. I tried following code in Page_Load of UserCOntrolBase but its not working
Code:
this.Attributes.Add("style", "border-color:#FFFF66;border-width:4px;border-style:Dashed;");
What should I do to make it work?
When I try to edit the Identity Specification from No to Yes there isn't a way to do so. No drop-down arrow or any way to edit the text. How can I change it so that I can actually change the value to 'Yes'?

View 4 RepliesI am working in a Silverlight 4 + RIA Services application. On the server side I am using Entity Framework and SQL Server. The user authentication is performed in the application using the default ASP.NET Membership Provider.
I am also using some profile properties to store some user preferences. Unfortunately I came across a situation where I have to change one of this properties in all users.
Altought I am using EF to manage data persistence, the ASP Membership provider tables are not in my entities diagram, since everything I must do regarding membership is performed using the objects available on the provider.
So I was thinking to use this objects to change the user prefrences, but my question is about what happens if something fails? Is there any transaction object I could use on the Membership objects to perform an atomic operation?
I know EF supports transactions, but in this case I would have to add the asp.net membership tables to my diagram.. only for that operation.
I have a dynamic gridview, about 35 rows by 11 columns. When the user hovers over a row, I highlight the row's background in green (with CSS:Hover).

View 2 Repliesi want to generate the output of an asp.net page by reading a text file, get the controls out of the text, change te properties of these controls, render it and displaying it.
so for example, the text file may contain:

</head>
<body>
<form id="form1" runat="server">
<div>
<sys:Label ID="Label1" runat="server" Text="empty1"></sys:Label>

</div>
</form>
</body>
</html>
after reading the text, i would like to change the properties of the sys:label controls. After that, the text will be rendered, and displayed.
I want to enable newly registered users on a site. I have figured out to put "DisableCreatedUser="True"" on the CreateUserWizard. What I have no idea about is how to have an email sent to the administrators email to notify them that a new user has registered.
