I'll change up the recommendations. If you only need Add() and Remove() functionality, I would say to use the Generic Collection class from the System.Collections.ObjectModel namespace instead and avoid the extra bloat of the Generic List.

Hi My Friends
I develop software with C#.Net 2005, Yesterday installed Borland Delphi 2006 on my PC for debugging and working another program, Delphi work correct and no problem but when switch to C#, see Runtime Error about float.Parse method.
For example if you write float f = float.Parse("2.3");
See below Runtime Error :
Input string was not in a correct format.
This method work in the previous and at now work on the another PC, I think System library conflict with delphi.
If you have solution for me, I will grateful from you.
Best Regards,
Reza Shojaee

Could this be a localization issue? Try specifying the IFormatProvider.
float f = float.Parse("2.3", NumberFormatInfo.InvariantInfo);

Thank you for your guidance,
I test your solution and get appropriate result.
But do you know why in the previous no need to determine NumberFormatInfo ?

I presume in your computer's language settings it's expecting a comma for a decimal seperator (2,00) rather than a period (2.00)
Invariant Culture just tells the language to always use "."

I suspect that maybe the install of Delphi may have triggered a change in your localization settings, or maybe a windows update? I can't be sure this is the case, though. I haven't run into a situation where my locale has changed without my intervention.

Reza Shojaie,
Works fine for me. So its something to do with your setup. Test it on a clean machine without delphi.

Do u want to make it null
.....

Why would you want to do this? As soon as you leave the exception scope, it's cleared.
|
|
|
|
|
If you just want to mask the Exception, have an empty catch block. But that is really not a good idea, catch blocks should never be empty, especially if you catch the System.Exception object. At some point, it will come back and bite you in the ass.

Do u want to create an icon for the desktop shortcut of your program? If so in your setup project under user's desktop tab create a short cut and provide the icon ( found in shortcut's properties)...

uhm ... I see but :
+ In my desktop, I have a Icon ( Ex: my computer ). Now, I want to move this Icon to ( x,y ) ( or Anywhere in desktop ) what should i do ?

hmm.. i think u can't do that ..I'm not sure abt it
.....
|
|
|
|
|
uhm ..
When u right-click mouse on desktop. Choose Arrange Icons By and choose type. U will see all of icon will sort and change location. So that i belive that It can be done. But ...
Who can help me ?
|
|
|
|
|
So you want to move the users icons? I don't think that is possible.
And like you said , you can 'Arrange Icons By...' which arragnes your icons, and if you have auto-arrange on, then you can't even move them properly yourself. Never mind with code.

Ok ! We will discuss it by this ex:
" I have a icon ( ex: My Computer ). I move it to A(x,y). And I restart, when windows logon I see this icon in A(x,y). So I wonder why win know where it is. How do window save info of it ? I had tried to find it in registry but I didn't see"
Do u have any ideal ?

Hi,
I am new to C#.NET..
I am building a C# application which searches for files in the HDD..
However there may be many duplicate files with the same name and same contents..
My objective is to delete the files with same contents..
So, say if there are two files (mscorlib.dll for framework 1.1 and another mscorlib.dll for framework 2.0), the application should not delete them, since they are essentially two different assemblies for different framework and should have different contents in it..
Where as say we have a file (abc.exe and another: pqr.exe) having the same contents(say I copied one and renamed it to another), they should be deleted, since they contain same contents and differ in name only..
How do I apply this?
How can I know the contents of a file?
Do I have to apply some checksome algorithm for that? If so, How? If No, then how to find out whether the contents of two files are same??
Please keep in mind I am doing this only for executables (.exe,.dll,.bat,.com etc)
Please guide..
Any help would be greatly appreciated..
Thanks..

This sounds like a nightmare. If you do it across your HDD, I will bet money you break somethings.
File.ReadAllBytes will load the files, then you can compare them.

Didnt quite get this line.. What might break??

How to compare them??
Any particular method in BCL or write an algorithm for that?

If you let a process run wild on your machine which randomly decides to delete exe's dll's etc there is a fairly good chance you will break your windows install.
ptr2void wrote: How to compare them??

You compare them by comparing their bytes. Try some code, read any exe on your machine using File.ReadAllBytes. Have a look at the return from that method (a byte array) and have a think about how you might compare 2 separate file's bytes (hint: a byte is essentially a number between 0 and 255)
