Hi there I still consider myself a newb, eventhough I have been programming asp for some years. But I still think that I can be much better :) I have been working hard to split my code in layers. #Presentation# #business/logic# #Database# But I still think that my programming style can be a lot better. I dont read or buy so many books, bcuz most of the information is available on the Internet. Therefor there will be some deep questions from me and I am suer that there will be alot of stupid questions too. I hope that I also can use this forum to get my programming evaluated and perspectivated. :) A lot of respect to everybody in here from me. I…

I am familiarizing myself with a bunch of different RFCs, and at the moment have a decent DHCP server programmed... One of the things a good server does is send ARP broadcasts to potential addresses to make sure that no other machine uses them. Long story short, VB.NET doesn't naitively support ARP and at the moment I'd rather not use the iphelper API. I've seen you can specify RAW for both the protocol type and the socket type, however, I've never been able to get it to send (or recieve) raw packets (meaning I want the entire header, etc. which is 'under' the IP layer, and thus, apparently inaccessible to .NET's sockets) Is there any way at all to recieve (or sen…

I am learning how to search through a dataset (using find with tables).. and i keep getting an error saying that I do not have a primary key setup on the table i am searching with... Do you'll have any ideas? Here is my screenshot: http://webpages.charter.net/trend/error.GIF thanks! Lee

--Using [VS C#.NET]-- Given a ComboBox [cb] that is populated by a dataset [ds from an SQL query] using the .DataSource method. cbJob.DataSource = ds.Tables[0]; cbJob.DisplayMember = "ID"; Want I need to do later on is get the ID (integer) value selected by the Combobox. However everytime I try I keep getting back a DataRowView (if I do cb.SelectedItem). Correct me if I am wrong but I assume the solution is to cast the .SelectedItem as a DataRow (or something) and then access the [iD] field? I have tried a few times and can't seem to get it to work, any ideas/help? Thanks

Hi All, I am building an e-commerce site on a remote server, which is going quite well. I have about 4 pages of this site that require a more secure connection as this is where credit card details will be given out etc. My webspace company provides SSL as part of the package, which I have just registered and I am awaiting for the permisions to be sorted at their end. In the meantime I was wondering what the heck I need to do to implement this. For example here is a snippet of code I have seen in a book that I am using as a guide: Response.Redirect("https://" & Request.Url.Host & Request.ApplicationPath & "/checkout.aspx") Currently the browser dies…

I am wondering what you'll think the best option for this scenaro: I have some software that needs access to the internet to send error reports and some other random stuff. This software accesses a db (right now an access db) to get pricing info and availability (availability is updated upon item purchased) and the db does some other random stuff. I really want this software to be able to use the internet connection to access an xml file on a websierver.. or an mysql server or ms sql server.. but my only problem is I am scared the internet might go down.. and if this happens, and no one can pull up pricing info and availability and there will be some pisses off p…

I'm having a very hard time getting j2sdk1.4.2 to work. I can write the code for a simple program in Notepad okay and save the file to my folder okay, but when I open up a command window and type the command to invoke the compiler, nope. No way. Does not work. And I've tried typing many different things and changing the path variable but all fails. Actually even though I pretty much a beginner to Java(I have done some console programming with C++) I would prefer to use a tool that will allow me to write my code in the code window, and secondly allow me to compile and run the program from within the IDE. Now my question is will J# allow me to do those two things? And c…

I'm doing a game and there are many variables that need to be shared across many classes (and in some cases across libraries). I do not want to just declare things as global and I don't want to deal with a nightmare of passing an object around as an argument every time something needs to get done. I just fear two different classes updating the object at near the same time and it just hurts my head. How about a shared Class? Or whats it called where you don't even have to instantiate it? Just have a class that everyone can access. I'm not quite up to this step, but I'm going to have to seriously plan for it soon. Any advice?

The buttons (also textboxes, comboboxes), that are desighned with same length in Visual Studio .NET are displayed with different lengths in Netscape 7.1. In IE everything is OK.
