You can speficy the default property of your class like this:
<DefaultProperty("propertyName")> _
Public Class MyClassType
' yada, yada, yada
End Class

No thanks man...
In fact it was just a point, the good one was the yours...
I have developed controls for web and windows forms... and in the moment I saw the attribute i thought in that namespace, where are all the attributes for the controls...
I thougth it was a good idea to mention it...

I now feel really silly for asking this question

Don't be. It's not a really obvious place to put an attribute like this. When I found it, I was looking for an attribute that I placed directly on the Property i wanted...

hi,
I am about to distribute my program on a cd to the customers. It has database .The program is written in asp.net with c# and SQL SERVER 7.0. I want the customers to run the program off the CDROM without having to install anything.
What do I need to copy to the CD beside my program and the database? I want my program to be able to run on every windows 95/98 OS computer. Or do i need to chage program to windows based vb.net or cshrp.net application with ms access as database.
Thanks,
Vijayendra.
Vijayendra Shinde.

You don't have a choice. YOu're going to have to install the application on the client machines. If you didn't have that database, it probably wouldn't be a problem.
But, if your app can run off the CD, there's absoutely nothing preventing the user from just copying the files to the hard drive and running it from there.

I wanna know if there is a way to make low-level operations to devices (mainly the hard disk) in .Net Framework ????? (Vb.net, c++.net or c#.net)
By ways I mean maybe a class or a Windows standard API library (doesnt matter if its not managed code)
Specific things I want to know are (mostly consultations) :
- the beginning/ending number of cluster and track of files,
- the beginning/ending number of cluster and track of folders
- the size in clusters of files
- the volume serial number
- the size in clusters and tracks of a hard disk, etc
- can I do "interrupts" ???
Let me know the class or the Api library and the documentation, if there is it.
thanks, fvalerin

You can call any C/C++ API from .net. That said, actaully writing any sort of kernel level code (I assume interrupts would qualify here) in .net is a bad idea. There's a performance hit with every call across the managed boundary, and with low level code you're going to have to do that very frequently. Secondly if you modify any system code that's loaded by other system apps you're injecting the version of hte .net framework you use into every one of them, and if they need a different version to work, you've just broken them.
If you just want to get the values there's no harm, but modifying anything at that level is a job for C/C++.
PS you're more likely to get the API names asking in the c++ forum.

I would like to implement this method in a control I have that is drawing text:
Public Function CharacterIndex(ByVal Position As Point) As Integer
'find the character within the drawn text closest to this Point
End Function
I can already do the opposite, which is to find the point of a given character in the string I'm drawing on my control:
Public Function CharacterPosition(ByVal Index As Integer) As Point
If Index = -1 Then Index = Text.Length
CharacterRanges(0) = New CharacterRange(Index, 1)
StringFormat.SetMeasurableCharacterRanges(CharacterRanges)
Dim Graphics As Graphics = pnlScroll.CreateGraphics
StringRegions = Graphics.MeasureCharacterRanges(Text, Font, LayoutRectangleF, StringFormat)
MeasureRectangleF = StringRegions(0).GetBounds(Graphics)
Graphics.Dispose()
CharacterPosition = New Point(MeasureRectangleF.X, MeasureRectangleF.Y)
End Function
Thanks in advance.

Add character ranges for each character in the text, measure them, and check which one is closest.

Do you by any chance have a 3rd party firewall? I have to disable ZoneAlarm in order to develop (and run) my ASP .NET apps.

I heard about ZoneAlarm being a problem a couple of years ago. Surely this should have been resolved in the latest versions?

This appears to be a mystery to everyone out there. But from what other people are saying about when they get the error, it appears that the project template files are corrupted, maybe? Try moveing the C:\Program Files\Microsoft Visual Studio 8\Common7\IDE folder to the root directory (C:\IDE), then doing a Repair/Reinstall on Visual Studio.

You posted your question in the .NET Framework forum. Something that MFC has nothing to do with. Repost your question in the Visual C++/MFC[^] forum and you'll get a better response.

You mean you want to find all the email addresses in the hotmail account in order to spam them?

Hmmm, you asked for a verry difficult task. I have some bits but, unfortunately, are in plain C, not for .NET applications. Sorry.
-- modified at 10:10 Friday 14th April, 2006
... I was voted down... how rude!!! Why? Because I speak about plain C and not about .NET??
 
...or because I dind't really help him with my answer? If he is interested, I could port my C code to C#, so no reason to be voted down!!!
