I have an application that uses Comparer class to compare the objects. In 4.0 framework, the function public int Compare(object a, object b) took much time than 2.0. Please help me to resolve this issue!!!

Could you show us the code you were using here? That might help to narrow things down.

Thanks for your reply. When i change the Target FrameWork from 4 to 2 in Project Properties in VS 10, it took less time.
Please find the below code snippet:
public static int CompareKeyColumn(DataRow drSource, DataRow drTarget, ArrayList arrForeignKey)
{
int iComareVal = 0;
string strColumnName = "";
Comparer cRow = new Comparer(new CultureInfo("es-ES", false));
for (int j = 0; j < arrForeignKey.Count; j++)
{
strColumnName = arrForeignKey[j].ToString();
if (drSource[strColumnName] != DBNull.Value && drTarget[strColumnName] != DBNull.Value)
{
iComareVal = cRow.Compare(drSource[strColumnName], drTarget[strColumnName]);
}
else if (drSource[strColumnName] == DBNull.Value)
iComareVal = -1;
else if (drTarget[strColumnName] == DBNull.Value)
iComareVal = 1;
if (iComareVal > 0)
return 1;
else if (iComareVal < 0)
return -1;
}
return 0;
}

My suspicion is that the problem actually lies with the culture. This is what happens inside Compare:
public int Compare(object a, object b)
{
if (a == b)
{
return 0;
}
if (a == null)
{
return -1;
}
if (b == null)
{
return 1;
}
if (this.m_compareInfo != null)
{
string str = a as string;
string str2 = b as string;
if ((str != null) && (str2 != null))
{
return this.m_compareInfo.Compare(str, str2);
}
}
IComparable comparable = a as IComparable;
if (comparable == null)
{
throw new ArgumentException(Environment.GetResourceString("Argument_ImplementIComparable"));
}
return comparable.CompareTo(b);
}To test this hypothesis out, try dropping the CultureInfo out and see what happens. (The m_compareInfo.Compare part is the test that occurs when you set the CultureInfo).
|
|
|
|
|
Sorry! I didnt get your answer. How to drop the CultureInfo? May i use Comparer.Default.Compare(object a, object b) function?
|
|
|
|
|
To test it, change
Comparer cRow = new Comparer(new CultureInfo("es-ES", false)); to
Comparer cRow = new Comparer();
|
|
|
|
|
I couldnt do it. The Comparer Constructor must take CultureInfo as Parameter. Default constructor is not available!!!
|
|
|
|
|
Doh. Of course it isn't. Sorry about that. OK, use the Comparer.Default.Compare(object, object) method to test the timings.
|
|
|
|
|
Ok. I will try and let you know

how to draw ecg waveform in wpf please anyone give tips...advance in thanks whomever helping me...thanks friends...

Follow one of the tutorials[^] out there.
You're welcome.

You should ask on the "Silverlight / WPF" forum. That's where the WPF gurus hang out.
That being said, start by looking at the Canvas control, and Line element.

i want in wpf please help me if u can
|

Canvas is in System.Windows.Controls and Line is in System.Windows.Shapes. Also look at System.Windows.Shapes.Polyline.
These are WPF.

A third party tool can help you generate waveforms.
There is a sound visualization library available here[^].
In addition, you can check out this article[^].

Hi there,
I am an experienced programmer however I have no experience with .Net. Can anyone please recommend me a good introductory level book about .Net platform? For now I am not interested in books about particular .Net programming languages like C# but primarily about the .Net platform itself.
I am also interested in a book about the .Net API. For Win32 there is a good book on Win32 API programming - "Programming Windows", 5th edition by Charles Petzold. The book is an excellent guide on native Win32 API. Can anyone recommend me a similar book on .Net API?
thank you in advance for the answers!
kind regards

It's hard to use the framework without a language, and it's not recommended. I suggest you start with Head First C#[^] from O'Reilly, reading Mannings' C# in depth[^] right after that.
The most used languages for the framework would be C#, VB.NET and C++. The latter two were alive before the framework, and come with their own history and quirks. C# was new, and combines the best from those two languages.
All those languages are compiled to IL, which you could learn too[^]. It's just not recommended to actually program in IL, since it would be a bit inefficient to do so; it's error-prone and time-consuming, compared to writing your code in a higher-level language. It is helpful to take a look at it still; later on you'll be using a disassembler like ILSpy.

The Windows 95 resource kit[^] might be interesting, but the best book on WinAPI is a collection of blog-entries from Raymond Chen. You can find his blog here[^].
Hope this helps

OK I will read the books on C# first, but what about the best book about the .Net platform itself what is the main question here?
Also are there any recommendations on the best book about .Net API? I am not looking for a reference (MSDN would be a good reference on .Net API) but a book that is written like a guide on .Net API in a similar way Charles Petzold's book on Win32 API.
