A friend of mine told there's a number on each harddisk; this number is unique. So it can be used to make sure nobody can copy ypur software (the customer needs a hash code from this number to use the softwarer)
Does anyone how to obtain this nuber in C, C++, C# or Java?
Thank you in advance

I have used this sometime:
char VolumeName[200]="";
char FileSystem[50]=""; //FAT, FAT32, NTFS, CDFS, ...DWORD VolumeSerialNumber=0;
DWORD MaxFileName=0;
DWORD dwFileSystem=0;
GetVolumeInformation("c:\\", VolumeName, sizeof(VolumeName), &VolumeSerialNumber, &MaxFileName, &dwFileSystem, FileSystem, sizeof(FileSystem));
CString VolumeSerialNum;VolumeSerialNum.Format("%X",VolumeSerialNumber);VolumeSerialNum= VolumeSerialNum.Left(4) + CString("-") + VolumeSerialNum.Right(4);

Thanks for helping me with this C++ implementation,
but I noted yesterday I need a C# version; because I need to implement it in a C# program. Can you help me with this one too?
Thank you in advance

All you have to do is lookup the function name at microsoft
and read the info and use it with [DllImport()] attribute.
This is What I came up with doing a simple search with google.

When a file entry is right-clicked in Windows Explorer a dialog appears with a minimum of a "General" and a "Summary" tab. The "Summary" tab always contains entries for Title, Subject, Author, Category, Keywords and Comment.
The .NET FileInfo class allows access to name, created date, etc. but not to the properties listed on the "Summary" tab.
How can I get to this "Summary" info with C#??? I don't event need to change it, just access it.
Thanks.

Why is it happen that, when I'm setting the AutoScroll option of the main form to be true, it makes multi copies and dirt of the text I'm writting by using GDI(DrawString method) through the Paint event of the main form on every time I'm scrolling/resizing the window.
I'll be gratefull to receive your help.

Call Invalidate() after the scrolling/resizing.

I have run into that before... You need to either apply a translation transform or take into account the offsets of AutoScrollPosition. (There is a bug in AutoScrollPosition; the AutoScrollPosition requires a positive value if you set it; but it always returns a negative value when you read it.) Just add the values from AutoScrollPosition to all the coordinates in you Paint routine.
The size of the scrollbars are determined by the bounding area of all the child controls contained within the control. TO change this, you can set AutoScrollMinSize to the actual size you want.
What is happen is that Win32 ScrollWindow (or whatever it is called) is being called, and the invalidated region is then asked to paint itself, but without including the offset position.
In addition to the above, there should be some OnScroll event (I don't remember the name). Try calling Update() within the event to perform realtime updating as you scroll. This removes the redrawing delay that occurs when they user is continually dragging the scrollbar, and defering any paint events from being generated.
Just doing invalidate() doesn't work because it flickers--also, it doesn't take into account the scroll position, so your client area never actually scrolls.
Thanks,
Wes

I wanted to share two important news with you. A new (and free) C# decompiler has been made available by Lutz Roeder. Reflector[^] was in the past "only" showing IL(L) code. Now Reflector embeds a C# decompiler plugin and it comes just as the definitive tool to unmasquerade all those CLR secrets...
Reflector comes even handier than predicted with the use of hyperlinks to navigate through methods within the source code. Amazing!
Anakrino[^] 1.1 has been updated. In fact, only the xml configuration file needs an update. Get it here[^]. Replace the xml file in your Anakrino install folder with this one. Caution : this xml file references paths of the form C:\WINDOWS\... and, as a consequence, you are very likely to have to replace those occurences with C:\WINNT\... Otherwise, Anakrino raises an exception when it starts.
With these tools in hands, it is possible to know how EVERY .NET class is actually implemented.
For native calls, just give a look at rotor.

Well, if you have a class highlighted in the TreeView, you can hit enter and it'll jump to its base type. Or if you have a method selected, hit enter and it'll jumpt to its return type. And the links were there in the IL as well.

I've been looking at Rotor. It's fairly interesting. I've been contemplating installing it so I can program against it. Maybe I'll even install Mono.

When you see the immediate benefits of these tools for those wildly posting issues, it's too bad we don't clearly show permanent links to these tools in the forum. Quite cheap an improvement.

I don't think so. I am even thinking about giving up the interop stuff altogether, and go to a more creative side (ASP.NET). So, may be bye bye C# forum and good morning ASP.NET forum! 
All those interop details are much like learning by heart tons and tons of tiny details. We developers were sold seamless interop, and the truth is that, just to give a crude example of where we developers are now, the CLR 1.1 does not even release running COM instances when told to (chris brumme blog).
Someone bold enough could rewrite the entire Windows Forms code, or sell a total replacement. It's clearly lagging behind today's needs, especially when you see how people are used to MFC controls and the like. After all, that's business opportunities for companies like Infragistics. According to me, this portion of the run-time is utter crap (internal classes, too tightly coupled with WIN32 controls, while being hardcoded at the same time).

Interesting thought, maybe you should suggest this to Chris in the Suggestions forum....

Not sure how much of a UI designer you are for Win32, however if you haven't done much web stuff you will soon hate the limitations.

I am creating a console sort of like quakes in which the user can modify variables and execute commands by typing them into a command line. So I have a Shell class which keeps track of variables and commands that are registered to it. Each command that can be executed has a delegate to the function that it calls when the user types its name in. I want to know if its possible to pass a function name as an arguement to another function, the purpose being that the Shell class would take care of creating the actual delegate. I noticed that in the delegate constructor it uses the parameter void() target, but when i try that it generates a bunch of errors. Any help would be appreciated.
Thank you.

You'll have to wait for .NET ver2 for anonymous delegates, in the meantime you will have to template each of them, or maybe you can use Reflection.Emit to build delegates dynamically, but that a bit difficult.
another suggestion is to go the COntrol.Invoke way, not sure if you can define a delegate with a "params" parameter.

Hi There !
I'm trying to create a Windows Service (not a Web Service) in C#.
I am using VS.Net Enterprise Architect:
Microsoft Development Environment 2002 Version 7.0.9466
Microsoft .NET Framework 1.0 Version 1.0.3705
I read about installutil.exe but I can't find it.
Can someone tell me where can I find it ?
Thanks.

Perhaps you'll need some more files. You can get them all by installing the .NET Framework SDK instead of the Redistributable version you may have installed. You can find the SDK here[^].

There are 4 fields in my database table. First fields is an integer, second is a string, third is a date field, and the fourth is a currency field.
I am using a combo box to select the field to be search, a text box for the value of the field to be searched, and a command button once clicked will invoke the filter.
Items in the combo includes the 4 fields names and another item "<everything>" which will disable the textbox for the filter value but once the command button is clicked, the recordset will be refreshed and set filter to nothing.
How to implement it. Please show example statements to filter using each of the above 4 fields. Also please include how to set the filter to nothing.
Thanks in advance

I suggest using the excellent Sharkbite IRC library on SourgeForge. It gives u a solid framework to build a GUI on.
