View 3 Replies I have an application that allows admins to add types such as document types and training types that are in seperate tables with a foreign key in a transaction table.
When structuring my class I decided to go with an abstract-like pattern (without the factory methods though). So I have a Type abstract class that defines my Save, Delete, and GetList methods. I have a training type class that inherits this class. The thing is all types have 3 main properties - defined in the abstract base - but have different source tables and thus different store procedures in my DbCommand object. So basically I repeat setting up the same parameters on all the derived classes. I would like to implement the common stuff in the base but I am getting thrown off by the difference in data sources.
I need to know how many ways I can lock a file? Suppose a process has opened a file and reading or writing it, by this time another process try to open it and read or write, how many ways I can impose lock level on that particual file? So, that the data remain consistant.I'm using VS 2005 and OS is Windows XP or Windows 2003 Server.

I want to limit the allowed uploaded file types to images, pdfs, and docs. What is the recommended way to approach this?
I assume checking the file extension alone is not enough, since an attacked can change the file extension as he wishes.
This is basically for a course management system for students to upload assignments and teachers to download and view them.

View 1 Replies to define a variable/property of more than one type. Let's say i want a property TextWebControl that is a WebControl and also implements Web.UI.ITextControl(f.e. like a TextBox or Label). But i don't want to enforce that it is a TextBox or Label, but only one that inherits from WebControl and also implements ITextControl so that it also would work with controls added in future releases of .Net-Framework.
.Net-Framework 4.0
Edit: I have retagged the question and added VB.Net because it's my default language. Normally it's no problem for me to understand C# also, but i must admit that it's difficult to translate generic stuff to VB.Net without experiences and it's also better documentated in C# than in VB. So i would appreciate(and aceept) a working example of a VB.net generic type of ITextControl/WebControl.
From Marc's answer i understand that i need a generic class. But how do i instantiate it in SomeClass? This won't compile:
Class SomeClass
Public Property info As InfoControl(Of WebControl, ITextControl)
End Class
I need to separate IE and FF browsers from others it's a pseudo-code :
If (CurrentBrowser == IE(6+) or FF(2+) )

...
}
else
{
...
}
in protected void Page_Load() event (think so)
if ((Request.Browser.Type == "IE") || (Request.Browser.Type == "FF"))
{
WebMsgBox.Show("1111");
}
no effects :-/ what is IE and FF types?
I have various classes which all contain address details, i.e. AddressLine1, AddressLine2, AddressLine3, Suburb, Town, etc.
On the front end, I need to format the address in a particular way, i.e.
AddressLine1<br />
AddressLine2<br />
Suburb State Postcode
If AddressLine2 does not exist or empty, don't show it. Quite straight-forward. I am trying to determine the best way to show this info. At the moment, the Address property of each class calls a FormatAddress method which writes out the html string. This exists as a method of the class. My opinion is that any formatting should exist from the front-end control i.e. ascx etc. However, if these DetailClasses need to format the same address info, what would be the best option, also making it easier to maintain?
I have IEnumerable object with value1 and value2. value2 is an array and value1 is string. I want to databind this object to Listview like that. So both value1 and value2[0] (always first item in array) could be accessed via <%# Eval("value1") %> and <%# Eval("value2") %> .
How to write expression to handle both items ?
ListViewItems.DataSource = f.Items.Select(t => t.value1, t.value2[0]);
ListViewItems.DataBind();
I am building an ASP.NET application that needs dynamic tables. That's another issue that I've already posted about (and gotten a pretty good response!). Now, I'm running into another issue - I want to add new rows to my table, but given that I will have 10-12 tables on one page, each containing different objects in their rows (text boxes, check boxes, etc.) I need a way of simply generically adding a new row that has the same objects as the first row in the table. Here's my code:
Private Sub AddTableRow(ByRef originalTable As System.Web.UI.WebControls.Table)
Dim originalRow As System.Web.UI.WebControls.TableRow = originalTable.Rows(1)
Dim insertingRow As New System.Web.UI.WebControls.TableRow
Dim insertingCells(originalRow.Cells.Count) As System.Web.UI.WebControls.TableCell
Dim index As Integer = 0
[code]....
I had asked with one question in the interview regarding generics
How can we restricts the one generic method to take only the value types.It should not be able to take reference types.
I have a .txt file and i open this file, read it and encrypt and decrypt it, it works fine. Now i want to read all types of files like .png, .pdf, .doc etc and do encryption /decryption. file.readtoend() does not work here. How can i do tht?
