I have a 2-dimensional integer array of the same width and height of the image, each of whose elements is either 1 or 0. Condition A just checks whether the corresponding element in the array is a 1 or a 0, and sets the pixel accordingly
There doesn't seem to be a major drop in the time taken by the overall routine though. Do you have any suggestions?

If it's just an array lookup, then it probably is fine, I thought it may be missing () and be a function call that did goodness knows what.

Hi
I am working on a project where I have a class containing a field of type object. I need to get a deep copy of the class, but cannot see an obvious way to copy the value of the field whos type is declared as object. I have considered using reflection to try and achieve this, but was wondering if anyone knew of a simpler way.
Any suggestions would be greatly appreciated.
Regards
Sam

Just serialize and deserialize it out of a MemoryStream. The framework takes care of the rest. Something like
using (MemoryStream s = new MemoryStream())
{
BinaryFormatter f = new BinaryFormatter();
f.Serialize(s, obj);
s.Seek(0, SeekOrigin.Begin);
object o = new BinaryFormatter().Deserialize(s);
Console.WriteLine(Object.ReferenceEquals(o, obj));
}
Regards
Senthil

Hi all,
I am working on Microsoft Installer project to create a setup for a software. The project is already existing and working. However now I have changed the folder hierarchy i.e. I have now changed the folders from where the files to be packaged are extracted. In the project, in Properties page there is an entry SourcePath which displays the path where the file is present. This entry is still showing the old path of the files. I can't change it's contents as it is read-only. So is there any other way to change the path? If so please inform me.
Thanking You.
Regards,
Harshad

No. The VS.NET Setup creation IDE is very limited and poorly designed. The only way to change the source files is to delete the existing ones from the setup project and add the new ones.

Dear all,
My .Net WinForms Application quietly closes off without a warning and I am unable to understand the root cause of the problem, as it happens sporadically.
I am working with .Net Framework 1.1 on Windows XP (tested on both SP 1 and 2).
I tried the following:
- Having a try/catch cover on all the important event handlers (OnPaint, OnMouse..., etc) and in the static Main() method (Application.Run(...))
- Set an UnhandledException handler for the present App domain.
- Earlier, I was creating and releasing a COM object in a method that was being called many times. Now, I moved the creation into the class constructor and the releasing into the Dispose().
Yet, none of these options have either stopped the crash or have given me a clue.
Is there a way in which I can get hold of any low level API's or tools that will be able to execute my application in a shell, which will give me a greater control on locating the cause of the crash.
Any ideas will be greatly appreciated.
Thanks for reading.
-Rajesh.

Put a try/catch inside your static void main so you can catch the error and get a stack trace.

Seems to me if he was getting an unhandled exception that was causing the application to 'crash' the he would be seeing some type of exception dialog box before the app 'closes off' though.
If this can be seen under some type of controlled circumstances perhaps running the app in the debugger a while might shed some light on things. At very least he might get to 'see' it happen and maybe get some debug info that way.
When chasing things like this I usually start by gathering some statistics as to what the application was doing at the time it 'goes away' so I can get a better idea where to instrument things a bit. I then add some debug print statements and run the app with something like debugview running to get an idea as to what code was being executed last when the error happened.

As i said in the beginning itself that i have a try catch block in main also, but that is of no use, when it crashes. It still crashs without informing anything...
And i have tried to monitor the crashing procedure, but there is no similarity among the different occurances. I could only suspect on the Out of Memory Exception, for which i have made sure from two memory profilers that all the objects which i create, am also disposing them when they go out of scope..
I think that the problem might be at some lower level(OS level) which iam not able to get it right!!
Thanks for your suggestions.
Regards,
Rajesh

Try hooking into the System.Windows.Forms.Application.ThreadException event. Other than that I have no idea  . Normally at least an error dialog should be displayed.

If this COM object, or any other Interop call you do, call the ExitProcess() API, you'll see the behavior you described: the program closes silently, without any exception. To try isolating the problem, try to remove the COM object and any interop call, even if your program does not work, and see if still closes. If it does not close anymore, try adding each interop call you do until you find what is the culprit.

What I wanna do is to be able to fill an ArrayList from my designer...
what I got is this
public class WebCustomControl1 : System.Web.UI.WebControls.WebControl
{
private ArrayList liste = new ArrayList();
.
.
public ArrayList Liste
{
set
{
foreach(string ele in value)
{
liste.Add(ele);
}
}
get
{
return liste;
}
}
....
If I fill the Array 'hardcode style' I can see the elements but I can't add new elements in the designer...

public string Liste
{
set
{
liste.Clear();
char[] seps = { ';'};
String[] values = value.Split(seps);
liste.AddRange(values);
}
this seems to solve my problem but is there no other way?

How i can close a form created in a local scope of function with new key word.
Form is a child of main mDI form.
Secondly How object of local scope like form object remain there as local objects of functions get destroyed with function scope
Thanks in advance

I suggest you read up on Garbage Collection (GC). In .NET, reference types (Form is a reference type) are not destroyed when they leave the scope, instead there is something called a garbage collector that does the memory cleanup when it decides to, based on a variety of factors.
[EDIT] To answer your first question, just declare a member variable to hold the form, you can then Close whenever you please, on the member variable. [/EDIT]
Regards
Senthil
