Is it only location which is saved in database or the image?
In case, it is only location you can use
Server.MapPath(##resultfrom DB##)

Hi All,
I want to sort collections..
// Class
public class Item
{
public String Name{get;set;}
public int Cost{get;set;}
public Item(string name,int cost)
{
Name=name;
Cost=cost;
}
}
// Collection of Data
List<item> items=new List<item>();
items.Add(New Item("House",100));
items.Add(New Item("Car",80));
items.Add(New Item("Dog",10));
items.Add(New Item("Car",50));
items.Add(New Item("Cycle",25));
items.Add(New Item("Car",120));
Note:
Provide code to sort a collection of Item. The code should sort the Item collection only one time, following this rule: The Items should be ordered by their names (following the standard C# API for string ordering), but if two Items have the same name, then those Items should be ordered by their cost, with the lower cost item to appear before the higher cost item.
I appreciate somebody provide solution for the same.
Thanks & Regards

IEnumerable<Item> sortedItems = from i in items
orderby i.Name, i.Cost
select i;
Also look here[^], for more complex examples.

Use this
public class Item : IComparable
{
public String Name{get;set;}
public int Cost{get;set;}
public Item(string name,int cost)
{
Name=name;
Cost=cost;
}
int Icomparable.CompareTo(object obj)
{
Item other = (Item) obj;
If this.Name < other.Name return -1;
If this.Name > other.Name return 1;
If this.Cost > other.Cost return 1;
If this.Cost < other.Cost return -1;
return 0;
}
}
Then you can just do items.Sort()
Probably worth having a look at IComparable and IComparer interfaces.
You could alsi look at using List<t> in generics namespace.

Item other = (Item) obj;
int diff=string.Compare(this.Name, other.Name);
if (diff==0) diff=this.Cost-other.Cost;
return diff;
And using a generic IComparable, you wouldn't need the cast.

That's much neater.
Looking at the OPs code I think they are a beginner, that's why I did it like I did and suggested looking at the interfaces.

Hello All,
Is it possible to read from the working set of physical memory of a process I have identified (but do not have source control over) on my machine? Also trying to automate the windows forms associated with that process. I have been through the win32 api and have been able to get the handles I want, but cannot, for example, access controls or any other property other than handle and text(title).
Thanks in advance.

Hi,
yes you can interact with the memory belonging to another process; it takes P/Invoke to call Win32 functions such as ReadProcessMemory, WriteProcessMemory, VirtualAllocEx
I would suggest you search this site for articles with such keywords.

Hi,
I am working on a MS Word Automation project using VS2008 and Office 2003 in c# language. I have a One Page Word template which have bookmarks in table cells. These bookmarks are placeholders where specific information is put in from database using c#. I generate say 10 documents based on the template and save them as seperate file. What I would like is to have a 10 page single document. I can use selection.insertfile to create this document. When I do this, all the formatting goes bersek.
Basically what i do is:
Word.Application app = new Word.Application( );
Word._Document wordDocument = app.Documents.Add(
ref originalTemplate
, ref oMissing
, ref oMissing
, ref oMissing);
Word.Selection selection = app.Selection;
int documentCount = MyGeneratedFiles.Length;
int breakStop = 0;
foreach (string file in MyGeneratedFiles)
{
breakStop++;
selection.InsertFile(
file
, ref oMissing
, ref oMissing
, ref oMissing
, ref oMissing);
try
{
if (breakStop != documentCount)
selection.InsertBreak(ref pageBreak);
}
catch (Exception ex) { }
}
wordDocument = null;
app.Visible = true;
This works as far as combining all documents is concerned. But the formattign goes crazy and there are no clearly defined pageBreaks. Is there a better way to combine multiple one page documents into one multi-page single document? I have been stuck on this for a while, any help will be much appreciated.
Thank you

I have a wrapper class for a digital camera that is called from my form through camera.blah.
In the camera class there is a callback function for when the user pushes the shutter button. Within that camera class I can perform all kinds of things.
My problem is that I want to perform those tasks on the Windows form I am using, and I have no idea how to use the callback function to do something on my Windows form when the event is triggered.
I know this is difficult and vague, but without an idea of what to do here I don't know where to begin. I read that I cannot listen for events without using a delegate, which I am not familiar with.

It's not that bad really, sounds like someone tried to scare you..
You don't need to explicitly use delegates in order to use events, but of course under water there will be some messing with delegates (because that's the way an event remembers what it has to do when fired)
If you have an event you can just use += on it, and let intellisense do the rest (just press tab when it asks you)
|
|

Delegates work like this:
public class Camera
{
// There is a delegate here which will inform you when the shutter button is pushed
}
public class SomeListener
{
// Here you add a handler for the delegate
// You create an instance of the delegate found in the Button class and provide it with a method
// The delegate will carry out the method for you
// Your method must have the same signature as the delegate in the Camera class
// Within your method you will do something you want
}
Here is a button class which has a single event. The comments will guide you.
public class AButton
{
// This is the delegate
public delegate void ButtonClickedHandler(AButton sender, EventArgs e);
// This is an event which is basically an instance of the delegate
public event ButtonClickedHandler Click;
// Here is a method which will raise the click event
public void ClickMe()
{
// In C# first you check if anyone has created an instance of your delegate
// Whoever has created an instance is called the subscriber or listener
if (Click != null)
{
Click(this, EventArgs.Empty); // Call the listener's method that has this signature and let it do whatever it needs to
}
}
Here is a listener:
public class Listener
{
// First create an instance of the class
public Listener()
{
AButton b = new AButton();
// Now listen to the event
// Remember the delegate requires you to pass to it a method which has the same signature as the delegate
// This is like saying: "Hey a (which is an instance of AButton), when you are clicked please do what I want
// you to do in AButton_Click method.
b.Click += new Click(AButton_Click);
}
// Here is the method
private void AButton_Click(AButton sender, EventArgs e) // Same signature
{
MessageBox.Show("The button was clicked and this is all I want to do.");
}
}
}
}
