Hello people,
My company has a set of COM components that all have the same interface, so we use CATID's to allow the user to select which component to use.
I have succesfully wrapped one of our components ina .NET wrapper using the MS tools, and it works fine from C# etc. However, I cannot find a .NET equivilent of the CATID mechanism to categorise a set of comnponents with the same I/F.
Can anyone point me in the right direction? I know there is a recent article of actually using CATID in .NET, but I was wondering what the .NET systme would use natively.
TIA

how come i cant override the public virtual method 'Clear()' of the System.Collections.CollectionBase class?
when im trying to override it im getting that error:
"C:\Documents and Settings\Roy\My Documents\Visual Studio Projects\WebEngine\Class1.cs(49): 'Goblineye.Projects.WebEngine.EditorCollection.Clear()' : cannot override inherited member 'System.Collections.CollectionBase.Clear()' because it is not marked virtual, abstract, or override"
however, the method does declared as virtual...
here's the method declaration (provided by MSDN):
public virtual void Clear();
You can spot it right here:
CollectionBase's Clear() Method
i would be grateful for any help.

At the bottom of the page is a link to tell microsoft about it. If your mail client supports it then the link will open a new email with the subject line appropriately populated. Write your comments in the body of the email.
If you want to override the behaviour of the Clear() method then I suggest you override OnClear() [which is called before Clear()] and/or OnClearComplete() [which is called after Clear()] instead.

I'm working on writing a custom menubar/toolbar set of classes, to replace the standard windows menu bar in my applications. I would like to have a fully custom-drawn, pure C#/.NET coded paint method to draw the popup menus for the menubar. I've run into the little problem of needing the screen DC to be able to properly draw the popup menu outside the bounds of the menubar control, though.
Is there any way to get the screen DC using GDI+, so I could draw to it as if it were a standard windows control? I remember being able to do this long ago before the days of MFC, but I havn't tried since. I havn't had much luck finding any documentation on how in the MSDN help, nor by browsing around the articles here on CP.
Any help is greatly appreciated...

Try calling GetDC using WIN32 interop.
Like this:
Step 1. int hdc = GetDC (0) // Gets the screen DC
Step 2. Get a graphics object from the DC and draw
Step 3. Dispose the graphics object and call releaseDC like this
ReleaseDC (hdc, 0)
Thanks

Thanks for the reply. I assume the GetDC() function is in gdi32.dll? I use C#, not C++, so I have to DllImport it to use it.

Hi all
I'm building a C# application to run on a PocketPC. What I want to do is be notified when the device is docked. This way I can connect to our server and refresh some internal information. The info doesn't live on the desktop machine, so it has to be retrieved via a TCP connection.
I've had a good look through the MSDN examples, and I'm feeling a little lost and confused. It speaks about a function called CeRunAppAtEvent which appears to be precisely what I want. But I don't know how to get this running successfully in the C# app.
Any help or even pointers would be greatly appreciated.
Thanks in advance

Hi, everybody,
Rightnow, I installed my Visual Studio .NET 2002 in my pc running Windows XP with .NET framework 1.0.
My question is : If I download .NET Framework 1.1 and install it on my pc, does my vs 2002 use the new framework 1.1? If yes, how can I check it?
Thanks in advance!!

For every version of the .net framework, Microsoft releases a new version of vs.net.
- Visual Studio.NET 2002 -> .NET framework 1.0
- Visual Studio.NET 2003 -> .NET framework 1.1
- Visual Studio.NET 2005 -> .NET framework 2.0
To answer your question: You can't use an older version of visual studio to work with a newer version of the framework.

I think a more accurate statement would be:
So far for every version of the .net framework, Microsoft releases a new version of vs.net
This may or may not continue to be true.

Sir,
Here Our Country and Language (Myanmar Burmese) is not supported microsoft window or any other OS. We have our own language, character, text, sort order, compare method and so on. But I, an idiot, have no idea to build an localized application without any OS sited NLS or something else. I want to know how to build .NET localized application for non OS national language support for our language EXACTLY.
We have our own font, unicode space, and ... HELP ME.

Hi Kyaw Zayar Han,
you can use some classes in System.Globalization namespace. It's quite late night and i am gonna wake up early in the morning, so I will write u more later...  Bt only in case u didn't already solve it! this post is quite old so maybe it's all done now. 
best regards,
David

Hello David,
I am so glad to hear from you about my problem. Yes I have ever seen the classes of System.Globalization at rotor of www.123aspx.com. I assumed that I have to create a satellite assembly class which includes some resources such as sorting table. Yet I don't know how to build the sorting table. It is sure that I haven't still solved the problem. Do you know it is so shameable to say that our country haven't still solved mother language problem for microsoft platform yet, even though we are taking some outsourcing and our developers have worked around the world.
Anyway, I feel compelled to know about your experiences and can't bear to wait learning from you. It'd been a long to wait to get response like yours. I thanks god and you for this.
Best Regards,
Kyaw Zayar Han

Hi Kyaw,
you wrote:

I think u should use class System.Globalization.CultureInfo. This class stores information about culture, like its calendary, sorting order, date/time format and currency. IMO you will have to set some properties like, say, CultureInfo.DateTimeFormat. This class has many properties, like DayNames. You will have to set these properties to comply with ur language. By playing with CultureInfo and its properties, u should be able to define all cultural-dependent things needed in localization process. Then, u will probably want to create satellite assembly, where will be stored (mainly) strings in ur language. In ur app, simply set System.Threading.CurrentThread.CurrentUICulture to your new CultureInfo instance. All the magic around strings are done with ResourceManager class. These are only basic ideas how ito solve ur problem. I never had to work with unsupported language so I belive this is the right way bt can be 100% sure.... I am awared this is not EXACTLY how to build .NET localized application, bt I don't have time nor feel like write it all... but I strongly suggest u to use (MSDN[^]) for additional information about all classes I mentioned & about satellite assemblies and resources etc.
best regards,
David

Hi,
Thank you all for ur answers.I tried working it out but there still is some problem.I tried the dllimport method but i still have an error saying that the entry point has not been found.this was using salford fortran .i was just wondering if all fortran compilers are compatible with .net platform.when i used the intel fortran 8.0 compiler i was not able to reference the fortran dll as well.the error was that it is not a valid dll or com object.i guess it cudnt recognise the dll.is there anything i can do to get it right??
the dllimport code i used was
_
Public Shared Sub xyz(ByRef x As Integer)
End Sub
call xyz(x)
and in the fotran dll i wrote the following
subroutine Dll2(x)
x=x+1
! Expose subroutine Dll2 to users of this DLL
!
!DEC$ ATTRIBUTES DLLEXPORT::Dll2
!MS$ATTRIBUTES REFERENCE :: x
end subroutine Dll2
this is just an example i was trying to get right.
i need to get it right soon.
thank u for ur help
