Thanks David.
Now I wonder how can IIS get a WindowIdentity from Windows 9x that running IE? Can I mimic the same behavior in our code (perhaps, by Win32 API)?

Hello All,
I am currently modeling a GIS geometry primitives like point, line, polyline, polygon etc.
Initially, I named everything according to the OpenGIS.org recommendations just to realize that .NET has the same name for Point and Rectangle.
My co-workers on Java project had no problem because in the Java2D, the names are Point2D, Rectangle2D etc.
GIS points are generally 3D but most applications are 2D.
What will you do?
(Please, I know about namespaces and I am using them, we just do not want to confuse the user of our products - it is a component not a standalone application so will be used by programmers.)
Best regards,
Paul.
Jesus Christ is LOVE! Please tell somebody.

Namespaces are an integral part of the .NET framework, or any good OOP language. Go ahead and use your own namespace. If programmers using .NET or Java, they should be used to qualifying (if they need to) your component objects by now.

Hi.
I HATE REGULAR EXPRESSIONS!
Oh, thats better.
Could someone do be a big favour and write a regular expression that will match to these examples. I'm doing a bit of URL Rewriting and its just causing me pain!
/resultsdownload_n_37.Zip
/resultsdownload_ma_3712.Zip
/resultsdownload_all_2337.Zip
/resultsdownload_out_121243.Zip
/resultsdownload_bottom_2321.Zip
/resultsdownload_fudgecake_1.Zip
Thanks guys. The Regex object is doing my head in!
E.g.
Why doesn't
/resultsdownload_net_37.Zip
match to
/resultsdownload_[a-z+]_37.Zip
???
Thanks again.
Pete

Ah. Sorted it.
It seems my + was in the wrong place. It needs to be outside the [] not inside.
Heres the final result if anyone is interested
/resultsdownload_[a-z]+_[0-9]+\.zip

i have a windows application which i previously written in others
computer using his microsoft visual studio .NET.
now, i had oledi made the change on the source code and want to
re-compile it using Microsoft .NET Framework SDK. this is becuase my
computer dun have license on microsoft visual studio .NET.
i was wondering how can i build my project which i previous done in
MSVS .NET by using Framework SDK command line? or is there any where
to generate a MAKE file in MSVS .NET and then build the entire project
using Framework SDK command line with the help of MAKE file?
thank you.
regards

Check out NAnt[^], it has a program (called SLiNgshot, if I remember correctly) which will parse solution/project files and either product .build files to use with NAnt or build the solution/project.
Many people on the DOTNET lists have recommended its use for any real projects using .NET. Apparently the build system in VS.NET isn't very viable when working with large projects (there are several known bugs that occur when building dlls/exes that are larger than 64K).
Once you know how to compile the smaller bits and pieces using the commandline using NAnt is a breeze. Here's a tip, .resx files first get compiled by resgen before being listed as a resource by the C# compiler (cs.exe).

First you need to tell it to build into a different directory than the default; then you need to have Copy Local set to false in one or more projects that reference that assembly.
Someone from MS commented on it recently on one of the DOTNET lists, I don't remember what he said about it though.

Well, OK! If it is such an effort to create the buggy behaviour it won't touch a lazy man like me

Is there a way to create a new event that occurs AFTER the check state of an item changes?

Just two suggestions though I don't know if they'll work:
1) You could override the mouse click event, and look wether the check state changed
2) You could override WndProc and try to intercept the corresponding Windows message, if it exists (might be a WM_NOTIFY with some code you can find in MSDN for the ListView common control)
Cheers

Martin,
That sounds like something to explore. If I use ItemCheck and then change the check state of the item inside the event handler, then it fires ItemCheck again, and we go into a circle. I suppose I could set some toggle bit, but that seems like a hack.
It seems like in other controls, that AfterEvent handles, seem to ignore changes relating to that event. Is my thinking correct? Am wondering how they do it?

 Maybe that's the case. But I don't know how this would be possible. Maybe for these controls only if the selection is changed via user input (mouse keyboard) the event get's fired and not if you change the property programmatically (event handler tied to the message an not the property). But if that isn't the case I don't think it would be possible to change the check state without goin into a loop, unless you override the property, but dunno if that's possible or even helps.
Cheers

You might be right, perhaps these events get fired based on something else?
It seem like what I am trying to accomplish would be a common thing. I want to put custom checkbox images in the listview. I've done this with TreeView using Genghis CustomTreeView. (In that, I use treeView1_AfterCheck which works fine if I change image states programmatically) http://www.genghisgroup.com[^]
ListView however is giving me greef. Here is a snippet of code as a sample that increments the image of the checkbox, that once I change the image for the checkbox it fires a new event.
I also wrote a custom state listview that sets the images using an Interop
by sending the state changes directly using Win32. But it causes the event to fire just like the example code.
private void listView1_ItemCheck(object sender, System.Windows.Forms.ItemCheckEventArgs e)
{
listView1.BeginUpdate();
int itemcheck2 = listView1.Items[e.Index].StateImageIndex;
Debug.WriteLine("Check image #: " + itemcheck2.ToString());
listView1.Items[e.Index].StateImageIndex = itemcheck2 + 1;
listView1.EndUpdate();
}
Thanks -- Perhaps someone has dealt with this.

I'm working on a wrapper to simplify the usage of the .Net cryptography classes, and have a few questions
I need answers for before I can use/publish it:
1) I am currently creating the key byte array for each alg by hashing a text password with UTF8 encoding,
is this the best practice for generating the key?
I understand that a unique IV should be used for each encryption, so that blocks of identical data are
different even with the same key. I am currently storing the IV bytes at the beginning of the encrypted
file, and reading them back when decrypting.
2) Does the IV being exposed like this weaken the crypto?
3) Should I be encrypting the IV with the key and a known IV before storing it in the encrypted file?

I have a .NET application and I'd like to distibute it in 2 forms:
1. As is.
2. Compiled to run on a Windows systems which may not have the .NET framework.
Is there a way to get a native application from a collection of assemblies? I looked into the ngen.exe program, but this appears to only pre-compile assemblies into an internal cache.

Somewhere on this forum, someone was asking about Obfuscators and wanted an opinion about something from Salamander software (IIRC) which turned .NET apps into native code. Find the link and see whether it still requires the .NET framework installed.

IIRC, Salamander is only a super-NGEN, you still need the .NET framework

This is impossible IMHO. You will always need your assembly (because of the metadata) and the framework (as the class library and to interpret it) even if you precompile your assembly (with NGEN for example).

And eventually all PC's will have the .NET framework pre-installed , just like all the VB/C++ runtimes. Its not all that different and could possibly decrease the size of an application if the application is very big.
I wonder if it is possible the make a cutdown version of the .NET framework like as in Java, where only needed assemblies are required and the "WebStart" it.

This is a huge problem with .NET
If you're a small company and generally don't distribute your apps on CD, .NET is severly limiting your potential market.
I've managed to compile C++ 6.0 using Studio.NET and the final exe does not require the 22MB framework but I have been unsuccessful with VB.net
I agree that EVENTUALLY, everyone will have the framework installed, but untill then, would you download a 22.1MB application or a 100Kb application?

I'd like to design a distributed system such that:
* Clients simply connect to the server, and wait for a callback. This is not an anync result, they are simply waiting for the server to call them. Think of this as the server firing an event for the client to respond to.
* Server does its thing. At times, it will need to perform a callback to a particular client.
I've seen examples on how to use delegates and shim classes to deal with my first requirement. But nothing I've seen suggests I can acomplish my second requirement. How can the server be aware of all the clients connected to it, and perform a callback on a particular one?
