Some compelling features off the top of my head:

-Tabbed browsing (hooray for tabbed browsing! This is the biggest advantage over IE, IMO)

-An easier-to-manage download interface, especially true with the new FireFox version

-Built-in download pause/resume

Yep. Those are pretty much the same features that Opera has had for some time. And I agree those are compelling. That's why I've had Opera on my PC for a while.

The 2 downsides to Mozilla is that it launches slower than IE, and renders some pages differently than IE (codeproject renders slightly different for instance).

Similar problems with Opera up to version 6 at least. That's why I still use IE as my primary browser and switch to Opera when I want to make use of the kind of features you mention. Full screen in Opera is implemented quite well. And Zoom is handy too.

So do I. In general, open source products have largely been useful to developers, not end users. MS, for all its faults, typically scores far higher in ease of use and usability, things which techies often neglect.

It occurs to me that some time ago Unix/Linux should have tried to do effectively a MacOS X.

As an aside, I also think that development on Unix/Linux sucks. That's my experience of a few years ago at least when I had to do some Unix development. I thought perhaps things would have moved on a bit, but it's not clear that they have.

Running C# programs

Hi

I want to create a small simple app that will help our users with there day to day jobs. In delphi this exe app would be around say 200k to download and install. Now if I create this in C# does anyone know how large this app could be. I've heard that you need to install the .NET framwork to run these apps and this is 20MB!! Is this correct or do you just need a cut down version? Or does XP / 2000 SPx include this framework?

Any info would be helpful - thanks

Creating a small application in C# usually results in a small EXE. However, you do have to distribute the .NET Framework Redistributable on machines on which you intend to deploy rich-client or console EXE applications, just as you must deploy the JRE for Java, VB Runtime Libraries for VB6, DLL's and MSVCR** for C++ applications, and, I imagine, runtime libraries for Delphi, as well. Windows XP and Windows 2000 SP* may include the redistributable, and it is definitely available through Windows Update. Plus, assuming the redistributable is already there, some applications may be deployed by "COPY *.*" rather than creating an installer.

Remoting Problems...

I am trying to call a delegate from a wellknown object, that has had a method added via the remoting client and recieved the following error:

System.Runtime.Remoting.RemotingException: This remoting proxy has no channel sink which means either the server has no registered server channels that are listening, or this application has no suitable client channel to talk to the server.

I only get this error if try to use a delegate for client callback from the wellknown object. If I strip out the delegate and event call from the wellknown object and remove the event handler from the client side... 1 way communication from client(s) to server works fine.

NOTE: I have also added a binary formatter with typeFilterLevel="Full" to the channel configuration, and made the client object serializable.

So my question is... How do I make the server object notify its clients that one of them has sent a message to the server, and what the contents of the message is? (message is a simple string at this point)

Could someone point me in the right direction please...
A word or two as to how i might accomplish this task...

I have since decided i was barking up the wrong tree D'Oh! | :doh:

, trying to use remoting for this task. It was really easy to do what i wanted with the System.Net stuff...

I could not believe how easy it was... Ofcourse had it not been for code project it would have taken me a lot longer to figure this out...

C# exceptions not showing filename/line numbers (PDB issue?)

Arun Bhalla2-Feb-04 13:12

Hi,

I'm developing an Explorer bar using VS.NET 2003 (C#) on Windows XP. For
some time, I've noticed that I don't have filenames and line numbers
appearing in my exceptions' stack traces. On the other hand, debugging with
breakpoints, etc. seems to work fine in VS.NET 2003. I can't understand why
this isn't working -- and I think it used to work, perhaps under VS.NET
2002, but maybe not. The information doesn't appear in exceptions when
running under VS.NET or when not.

I am running my Explorer bar (which is a class library, not an application)
on the same machine (and user account) which built the library. The PDB
file is accessible to me, and its location does match the location in the
assembly. I am making Debug builds, and I do have "Generate debugging
information" enabled. As far as I can tell, the PDB and DLL files are
equally fresh and the same version?

Any tips? Is this a known bug? It's driving me batty trying to locate an
exception in code blocks without any help from line numbers.

Thanks!
Arun

I had a problem like this when i downloaded and installed Borland's C# builder to check it out. It's installer reconfigured all of the debugging ide stuff to point at the borland stuff. It does ask though before doing this and warn you that debugging will not work in Visual Studio anymore. I would imagine that Borland Delphi 7 does the same thing.

May or may not be your problem. If not 1 down x to go...

Actually, I figured it out. I had been using the GAC, and the DLL was expecting the PDB to be in the GAC, too. I copied the PDB to the same directory in the GAC, and that worked. Later, I decided to not use the GAC for development work.

Thanks for responding!

DateTime structure has a property called "Now", will give you the datetime object has a current date and time.

I am trying to add a class to my user control that inherits from:

System.Windows.Forms.Design.ParentControlDesigner

But the only namespaces that I can get from System.Windows.Forms.Design are as follows:

ComponentEditorForm
ComponentEditorPage
EventsTab
IUIService
IWindowsFormsEditorService
PropertyTab
WindowsFormsComponentEditor

I don't know why I cannot get the expected namespaces including ParentControlDesigner, and I would appreciate any help on the matter.

1.Require a treeview control with checkbox functionality.
2. Can the backbutton on IE be disabled by the developer else how can you detect that the User has depressed the back button and force a redirect to the current page.

Changes in Remoting

In .NET 1.0, I have written an application using .NET Remoting. My remote component and the clients rely heavily on the use of events for communication. Ideally, when the component fires an event, the clients would handle the event and provide the necessary response. I have compiled this application in .NET 1.1, and everytime it comes to the point where my client creates an event handler for any event in the remote component, the application crashes with weird error messages. Folks have been telling me that this is due to the new security changes in .NET 1.1.
Does anyone know how I can avoid getting these errors? I will deeply appreciate any help you may provide.

Add this to your config file on the server side.

<serverProviders>
     <formatter ref="binary" typeFilterLevel="Full" />
     <formatter ref="soap" typeFilterLevel="Full" />
</serverProviders>

Add the line according to the formatter you are using.
