I need to use some classes inside the app_code folder of a website project in visual studio 2008. I need to access this code from a class library project in the same solution.

Am I being dense here? StreamReader.ReadLine states that: A line is defined as a sequence of characters followed by a line feed ("\n"), a carriage return ("\r") or a carriage return immediately followed by a line feed ("\r\n") So, why doesn't this work as expected? ' Server Dim tcpL as New TcpListener(IPAddress.Any, 5000) tcpL.Sta...

I've done a good deal of RS232 work using the .Net 2.0 serialport class. I've never had trouble with it, until today. I'm communicating with a piece of company hardware that uses the RS485 protocol.

I have a table TaskSchedule. It has a three-part primary key and two more values: IdTask PK IdPerson PK StartTime PK EndTime Remarks IdTask and IdPerson are also foreign keys.

Having been primarily a .NET guy up until starting a new job recently; I've only done Web-Service development and consumption in C#/.Net. However I'm embarking on the journey to learn the ins and outs of doing it on the J2EE platform, and I'm curious what the major differences are in this specific type of development. Note: I have famil...
In WinForms, you can know, at any time, the current position of the cursor thanks to the Cursor class. The same thing doesn't seem to be available for the keyboard. Is it possible to know if, for example, the Shift key is pressed? Is it absolutely necessary to track down every keyboard notification (KeyDown and KeyUp events)? Thank yo...

As mentioned in this question/comments there are certain disadvantages when moving from 32 bit .NET to 64 bit .NET. Probably the biggest advantage is the much bigger process address space in the 64 bit world, but what other pros and cons are worth noting? ...
I have an interface IScriptItem that implements IComparable<IQueueItem>. In my eyes it would seem enough to have IComparable items in order to have a sorted anything.
