You are right,Sorry.
I want to write a math program which displays on the screen a very large number of full quadrilateral shapes creating a mesh.
I find the cordinates of the four peaks for each shape and display it creating a mesh.
Next I calculate new cordinates for each shape and display a new mesh.
It happens continuously as faster as possible.
What is the fastest way to display i) a pixel ii) a full quadrilateral shape in C#?

Wait, is this some kind of trick question?  I think some more details would be nice

I think that the fastest way would actually be to use C++ and write to the screen directly (I'm not even sure if Windows lets you do this, though). However, you can find several helpful tips on working with bitmaps/images using GDI+ here: http://www.syncfusion.com/FAQ/WinForms/FAQ_c3c.asp.

I am logging events just fine for my Navigator application, however no matter what Event ID I pass to it I get the following message:
The description for Event ID ( 0 ) in Source ( Navigator ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer.
My question is what is necessary to create a message DLL. Is it just a DLL with enumerators for each Event ID I am going to use???
HELP!

You can add a log event source by using the static method EventLog.CreateEventSource (calling WriteEntry the first time will do this automatically, too). Then instantiate a new instance of the EventLog class, specifying the same source name in the constructor.
In order for event IDs to be resolved, you have to use the registry to add a key (see http://msdn.microsoft.com/library/en-us/debug/base/adding_a_source_to_the_registry.asp[^] for more details) that points to a native Win32 dll. The IDs match up with String resource IDs for the invariant or current language that the OS is using.

Does anyone know how to change the permissions or add a user to a particular registry key programmatically? I know you can do this manually with regedit so it follows that you should be able to do it programmatically. I just haven't seen any clear docs on how this might be accomplished with C#. I've looked at using the Registry functions in the framework, however, nothing stands out as a way to accomplish this. Any suggestions?
Thanks.

p.s. I am trying to do this from an installer/deployment app.

Jerk! 
Seriously though, all I see is information on reading the permissions, not changing them. Do you have particular links you can point me to?

p.s. I'm surprised at you leppie. You've not been a smart ass when answering my questions before.

Regards,
Hello every buddy, wishing all are coding greate(!) I have the following question:
Suppose following runtime invokation:
myInstance.getType().InvokeMember(aMember, BindingFlags.Public|BindingFlags.Instance|BindingFlags.GetField|BindingFlags.GetProperty, null, new object[] {});
If I execute this line while aMember is an inherited member property name of myInstance (not it's own) it works and returns the value.
Now if I call the same member and try to set the same member(inherited member property) it will throw an exception that 'Member not found'.
myInstance.getType().InvokeMember(aMember, BindingFlags.Public|BindingFlags.Instance|BindingFlags.SetField|BindingFlags.SetProperty, null, new object[] {newValueArray});
How can I fix this and set inherited properties of myInstance using Reflections?
Thank you

BindingFlags.SetField|BindingFlags.SetProperty
Get rid of that!
and this:
BindingFlags.GetField|BindingFlags.GetProperty
its not needed!
But better, use the GetProperty() method rather. Also ALWAYS check the return member info 1st, more than off its null , and then bang BIG BADA BOOM!

Thanks but:
If I get rid of 'BindingFlags.SetField|BindingFlags.SetProperty' then how can I set a property or field runtime using Reflection????

Ok, thread is over!
About my last question I got it now, using PropertyInfo.SetValue()... Thanks but:
I made a mistake posting this thread start. Type.InvokeMember(... BindingFlags.SetField|BindingFlags.SetProperty...) DOES return and set inherited types, the mistake was that I was tryong to set aMember into other type value than it's own, so Such 'aMember' with that target type could not be found and null would be returned.
Thank you and sorry for the mistake,

So: I have created ActiveX control inherits from the Control Class, as it written in Morgan Skinner's article. It was successfully registered in system, but when I have tried to add it in C# winform application, the mistake message was given:
"Converting the type library to a .Net assembly failed. Object reference not
set"
or if i try add .tlb file the mistake message was:
"Converting the type library to a .Net assembly failed. Type library was exported from a CLR assembly and can not re-imported as a CLR assembly"
What can i do? Что делать?

This post is rather puzzling. In the same sentence, ActiveX refers to something from the unmanaged world, and the Control class refers to something from the managed world.
Did you create an ActiveX control using an unmanaged compiler like VB6 or VC++6 ? If yes, then you can import it into the managed world by opening the toolbox window, right-click on it, select "Customize toolbox" (VS.NET 2002) or "Add or Remove Item" (VS.NET 2003), then click in the components tab, browse so you find the ActiveX dll, and finally drop it onto the form.
There are several cases however where the ActiveX import will fail. Most of the time, it just works.

I have created this control in С# in VS.Net 2002 => using a managed compiler
|
|
|
|

1) The C# compiler does not create ActiveX controls.
2) If you are in an unmanaged environment, it is possible to use a .NET user control like it was an ActiveX control, thanks to an undocumented technique, but I am not sure that's what you are talking about.
3) If you created that non-ActiveX user control with the C# compiler, then why don't you just include the .cs file in your other project? What is the tlb import for?

1. Thanks for lesson.
2. This control will be used with Delphi or CBuilder, that is why i need to do non-ActiveX control.
3.Do you know how can i do that.(use with Delphi)
4.(thanks to an undocumented technique) - what technique?
Thanks.

|
|
|

3) I would look around Delphi.NET and #Builder
4) Here[^] it is.
