http://search.msn.com/results.aspx?q=DirectX+cardinal+splines[^]
Apply that to Managed DirectX using DirectDraw ro to build meshes in Direct3D. Because Managed DirectDraw is deprecated you may have to P/Invoke DirectX APIs in order to draw splines. This site has several good articles about encapsulating the native DirectX APIs with some downloads you may find useful.
BTW, .NET does not use GDI but GDI+. Doesn't matter much in terms of your problem, but it's still worth mentioning. GDI is used only in rare cases like to get device capabilities (a la GetDeviceCaps). Everything in System.Drawing and its child namespaces uses GDI+, however.

Hi
At present The program what it does is reads any xml schem afile and load data's automatically for each fields in a new xml file. (ie, fora field name "company name" datatype-string - ( values stored as john1, john2..etc up to 200)like that.
Now what I need is , to give a meaning full data.
Ie, I have another xml file with same field name " company name" with meaninful data'a upto 200 data's.
Now I want to insert the data's from that xml file( that field "company name" alone) into the new xml field (company name").
Transferring a single field data's into a new xml file .
PLEASE HELP ME TO DO THAT.

I'm not sure I understand this or your previous post yesterday, but if I do understand you right you simply want to copy all the companies into a new XML file. Is that correct?
There's many ways you can do this. You could use an XslTransform to transform the one XML file to another without even loading the XML file into a DataSet. Using the right classes for the job is important. The DataSet class, for example, has a heck of a lot of overhead for just reading an XML file. Using the XmlDataDocument class is far better in terms of performance and functionality when dealing with the XML rather than the data itself.
For more information on XslTransform, read the documentation[^] for the class in the .NET Framework SDK.
If this is alread loaded into a DataSet, then get a reference to the DataTable that contains the company names and simply enumerate the DataTable.Rows. For each DataRow in DataTAble.Rows, get the company name field and either put it in a new DataTable using DataTable.NewRow, setting the column data, and adding the DataRow using DataTable.Rows.Add, or simply write out the data from the company name column into a file.
There's so many ways of doing this but you really need to read the .NET Framework SDK documentation for the classes to see what's possible.

Hi
I wish you a Joyful and Happy New Year.
I am new to c# , so I dont know how to do.
ie,
My requirement exactly is :
Now My program reads a schema file( with field names name(string), salary(decimal)).
They are read and the values are inserted to the fields automatically.Like
(john1,john2,john3,..etc. for name)(2000, 2001,2002 , ..etc for salary).They are written into a xml file(say for instance salaryemp.xml).
this is what happens to my program.
Now what I have to do , I should be able to read another xml file( say for instance corporate.xml) which also has this name field with many original datas( like james, george, munna,..etc. ). So my program should read these values and fed(insert) into salary.xml file(only the name field should get altered with the values of corporate.xml). the salary field should remain the same.
pls help me to do that .
Just give me a coding help.

Hi Everybody,
When I add a C# dll to a C# exe, using Add Reference. The "Copy Local" property of the dll is set to "True" for default.
Can any one give me info about adding the dll's to the exe and what property to be set and what are the pros and cons of the same.
Any article or link explaining the same would be very helpfull.
Thanx in advance.

First of all there's no such thing as a C# DLL or C# exe. The Common Language Infrastructure (CLI) of which the .NET Framework is Microsoft's implementation (Mono and Portable.NET are alternative CLI implementations) describes that managed languages are compiled to Intermediate Language, or IL. That's not to say the result from equivalent code in different languages is the same, but close (compilers perform optimizations and may include other features that other compilers don't have).
That being said, when working on a multi-project solution it's best if you use project references instead of assembly references. This creates project dependencies, so that changes in a dependent project will make sure it gets compiled first before compiling the target project. It also makes sure that your target project is up-to-date with the latest version of the assembly.
There are only three options for dependent assemblies: copy the assembly to the local obj and bin directories, install the assembly into the GAC, or use a runtime configuration file.
The first - copying the assembly locally - is best for development. You will undoubtably be changing your project often and the CLR needs to resolve your assembly. It will use the current directory, then a configuration file, then check the GAC (Global Assembly Cache). It does not use the PATH environment variables like native appliation loaders do, but you can set a separate DEVPATH for developmental purposes, but this is not recommended.
Installing the assembly into the GAC is only recommended for released assemblies, like third-party libraries you use or your own in-house libraries that have been released internally. For projects that change often this gets to be a real hastle and you need to reference the assembly to build anyway. The GAC is only used at runtime and referencing a GAC-only assembly (i.e., there's no assembly in a version directory, like there is in the %WINDIR%\Microsoft.NET\Framework\<Version> directory) in difficult because you can't use Windows Explorer (so not the Open or Save dialogs, either, so that you could browse for the assembly).
The third option requires that you update your configuration file and know about publisher policies, version redirection, codebase changes, etc. It's not worth it.
Note that "Copy Local" is for runtime purposes, as is everything about. The path of the assembly that you're referencing is still used to build against. If "Copy Local" is set to true, then the assembly is first copied but this is primarily for runtime. If the CLR can't resolve your dependent assembly an exception will be thrown and your application will not run.
For more information about how the CLR ("Runtime") resolves assemblies, read How the Runtime Locates Assemblies[^].
To learn about publisher policies and other runtime configuration settings, start by reading Redirecting Assembly Versions[^] along with the next few topics after it, including Specifying an Assembly's Location[^].

HI Heath,
Thanx for the inputs.
Iam very new to C# programming.
I think Iam still missing something.
Iam statically linking the dll's to the exe using "Add Reference" option.
And Iam setting the "Copy Local" option to false.
The outputs of the exe and all the dlls' are mapped to one output folder.
Consequently all the dlls' will be statically linked from the same folder.
Is this correct ???
Can u suggest some alternatives for static linking of assemblies ??
Any suggestions are welcome.
Thanx in advance.

There's no static linking in .NET. Assemblies reference one another, like dynamic linking. As I mentioned in my first reply - and be sure to read the documentation I linked for more information - the assemblies are copied locally for runtime purposes. Yes, if they are copied locally they are referenced during compilation, but if you don't copy them locally than the assemblies' source paths are used instead.
If the CLR cannot resolve the assemblies that are referenced by the currently executing assembly, an exception is thrown. This is not any different than native DLLs not being found in the current directory or in any of the directories in your PATH environment variable, only the CLR does not use the same rules. I also discussed that in my first reply and linked the documentation for "How the Runtime Locations Assemblies", which you should really read to gain a better understand of just what assembly references mean to your libraries and/or applications. After all, if you're new to .NET programming you won't learn if you don't read.
If you use project references using the Projects tab in the Add References dialog, you need not worry about keeping the assemblies up to date, though I recommend that you never use automatic versioning by leaving the asterisk (*) in the AssemblyVersionAttribute. You can loose control quickly, and in .NET the versions are important unlike most native DLLs.

Hi all,
I want to lock a particular method of the object, so it allows only
single access of the method at one time. But by using lock(this) to the
method will cause the whole object to be locked, so other methods can't be used. What can I do to lock the particular method only ?
Thanks
|
|
|
|

Create a new meber variable (e.g. object lockVarForMethodA) and reference a unique object of your choice (e.g. new object()).
Than use lock(lockVarForMethodA) in your method.

That's not true. The object is not locked in such a way that nothing else can use it. Unless a method also calls lock(this) or otherwise locks whatever object this refers to, the method can run in a separate thread (not in the current thread, of course, since you're already executing a method).
What Robert said is good, though. If you want to synchronize each method individually then create separate static instances of objects to lock against. These must be static so that they are the same object for all instances of your object in any thread within a single AppDomain.
If you're going to synchronize each method individually and don't need instance data, I recommend you make the methods static. The CLR will synchronize static methods allowing only one thread of execution to enter at a time within a given AppDomain. This would be the same as locking against separate objects for each method yourself and makes for a better design and uses less memory (additional objects are not necessary).

HI
"Unless a method also calls lock(this) or otherwise locks whatever object this refers to, the method can run in a separate thread (not in the current thread, of course, since you're already executing a method)."
That means if a class like this below:
Class class1<br />
{<br />
public void MethodA(){<br />
lock(this)<br />
{<br />
...<br />
}<br />
}<br />
<br />
public void MethodB()<br />
{<br />
...<br />
}<br />
}
Then using the same reference of a instance of class1, after calling MethodA and MethodA not yet finished executing within the lock, MethodB still can be called unless lock(this) is also used in MethodB?
Also is that the static method will be automatically synchronized and special keyword and code (e.g lock) is not needed to be implemented?
Is lock useless for single thread programming?
Thanks

That is correct. Just try it. The majority of code snippets I post here in this forum I simply type in a simple text editor and compile on the command line, then run. Simple.
ting668 wrote:

A single static method is synchronized by the CLR. If you want to synchronize different static methods you will need to use lock or some equivalent.
ting668 wrote:

Yes. Within a single thread you can only execute one statement at a time. With that in mind there's no way you could execute the same method (or act on the same context, like getting or setting a serial number) at the same time.

Hi Health,
Class class1
{
public void MethodA()
{
lock (this)
{
MethodB();
}
}
public void MethodB()
{
lock (this)
{
...
}
}
}
From the code above, statements in locking block of MethodB still successfully run which is branched within the lock from MethodA. Why it is not a counter example of the locking theroy of the point1 :
Then using the same reference of a instance of class1, after calling MethodA and MethodA not yet finished executing within the lock, MethodB still can be called unless lock(this) is also used in MethodB?
of the last reply?
Thanks

Because it's executing within the same thread - not a different thread. Synchronization is not a replacement for state. You really should read Threading[^] in the .NET Framework SDK, as well as about the Monitor.Enter[^] method that the lock keyword (SyncLock in VB.NET) compiles to.

Sorry for a lengthy post, but I am very new to events and delegates and want you guys opinion on this. 
Is this kind of encapsulation ideal? I have encapsulated the entire event functionality (the related event and delegate) inside the publisher class itself, and I think this is making it a lot cleaner that the MSDN example. (no offense)
using System;
namespace EventsAndDelegates
{
#region The Suscriber
public class WebClient
{
// Note the mathcing signature with the delegate
public void ShowStatus(ServerClass ContentServer, ServerClass.ExecutionCompleteEventArgs ServerEventArgs)
{
Console.WriteLine("Execution is finished. Result = " + ServerEventArgs.ExecutionResult);
}
}
#endregion
#region The Publisher
public class ServerClass
{
// Delegate for event handling
public delegate void ExecutionCompleteHandlerDelegate(ServerClass ContentServer, ExecutionCompleteEventArgs ContentServedEventArgs);
// Event of type the delegate define above
public static event ExecutionCompleteHandlerDelegate EventExecutionComplete;
// Event argument
public class ExecutionCompleteEventArgs : System.EventArgs
{
public int ExecutionResult;
// Constructor accepts Returncode
public ExecutionCompleteEventArgs(int ReturnCode)
{
ExecutionResult = ReturnCode;
}
}
// This class will fire this event when it occurs
public void OnEventExecutionComplete(ExecutionCompleteEventArgs ServerEventArgs)
{
// (Only) if somebody has subscribed to the event, notify them
if(EventExecutionComplete!=null)
EventExecutionComplete(this, ServerEventArgs);
}
// The method which will cause the event
public void ServerBigTask()
{
// Server does something big and on finish raises the event
OnEventExecutionComplete(new ExecutionCompleteEventArgs(10));
}
}
#endregion
#region The Framework
class AppClass
{
[STAThread]
static void Main(string[] args)
{
Console.WriteLine("Main started...");
ServerClass ContentServer = new ServerClass();
WebClient IEExplorer = new WebClient();
ServerClass.EventExecutionComplete+= new ServerClass.ExecutionCompleteHandlerDelegate(IEExplorer.ShowStatus);
ContentServer.ServerBigTask();
Console.WriteLine("Main ended.");
Console.ReadLine();
}
}
#endregion

It's not a bad design, but keep in mind that encapsulation != nested classes. Nesting classes (or any other types, including delegates) is typically when you don't want to share a type or even make it non-public. In the extremely dynamic world of application development, that's a pretty poor assumption.
You should design your object model to be extensible and assume little when possible. To that your delegate and related EventArgs derivative will only be used for this class is probably not a safe assumption. Besides - do you really want your clients to have to type all that every time they want to use it? Making your object model easy to use is also important in many libraries and applications.

Hi
I have done a c# program , such that my program reads any schema file and inserts values for that fields in a new xml file. ie, for exx : for the datatype string (john mathew1, john mathew2,..) for decimal(900.90, 900.89/..) like so on for about 200 values for every datatypes.
Now, I require you to build a program further. Imagine that you have an xml file which is just a list of values for a single field. Then within my program if I come across that particualr field , then I have to load the values from that xml file into the output file.
Here is my coding which i had done previously. please give me an idea how to give the coding.

Hi Folks!
I was wondering if I could know about any mechanism for selection of language in prgramming e.g. C#. By language selection I mean that if we have more than one languages installed on WindowsXP(Contorl Panel -> regional n .. ***), a language bar appears there to provide a choice of language selection.
Any one knowing if it possible....thanku inadvance;)

The short answer is that you typically shouldn't. Giving users a consistent UI for control tasks is important for user understand. In some cases doing this yourself can lead to problems if you don't do everything required. For example, setting the UI language (MUI language) requires the user session to end via a reboot or having the user simply log off and back on.
On MUI-supported Windows desktop platforms you can't set the UI language (though you can set the locale). You can on Windows CE-based platforms like Pocket PC, however, by P/Invoking SetUserDefaultUILanguage.
Depending on what you're doing, though, you don't need to do this. If you only want to display a different language and/or locale for your application via the built-in localization features, simply set Culture.CurrentUICulture and/or Culture.CurrentCulture to change the language and/or locale, respectively, for the current thread. Do this before displaying any UI, otherwise you'll need to re-initialize (not necessary re-instantiate) any controls.

I would recommend searching the forum first by click "Search comments" above. This topic has been covered[^] many times in this forum in the past. In fact, I just answered a similar question earlier today about scrolling to a particular line in the RichTextBox, so you could simply browse for that (probably on the next page of this forum) to see how.
