Feb 28, 2012I've written a series of ASP.NET pages which have several common methods among them. In my ignorance, the best way I was able to find to move those common methods to a separate file was in a Module. However, what I need is a way to identify from which page was the method called?For example, I have a method call WriteToErrorLog with the following signature:WriteToErrorLog(ByVal sender As Page, ByVal Source As String, ByVal Message As String, ByVal StackTrace As String)

View 10 RepliesCreate A Callback That Returns A Value To Its Caller?
Mar 1, 2011I am creating a class ("Class B") which is used by another class ("Class A") which instantiates it in VB.NET 3.5.I would like Class B to read a value assigned to one of its properties by Class A every time an event happens in Class B.However, I would like this property value to be dynamically assigned to the property by Class A when the event is fired in Class B.I was thinking about somehow creating a delegate function in Class A that is linked to the property in Class B so that when the event is fired in Class B it would eventually invoke the delegate in Class A so that it returns a value to Class B.I've been reading around delegates (that's how I arrived at the idea), but I am stuck on how to code this up - could someone please help with some skeleton code?

View 1 RepliesProgram To Randomly Select Numbers For A Bingo Caller - Prevent Reversed Numbers Being Selected
Mar 6, 2011I have just about completed a .NET project to write a program to randomly select numbers for a Bingo caller. Over the last month or so Ive learned a lot about .NET but heres something that I consider to be odd and maybe one of you guys can offer an opinion.
One of the features of calling Bingo in a small local club is that callers often use little sayings to accompany certain numbers, I expect youve all heard of (say) All the sixes, clickety click for 66 or 5 and 9 the Brighton line for 59 etc. My little program gives an option to incorporate these with a prompt for the caller that can be edited outside of the program. One of these conventional sayings is used when a number is reversed 12 followed by 21 or 45 followed by 54 for example, when the caller might call (say) 1 and 2, one dozen, number 12 And the other way round 2 and 1, twenty one.
So, I programmed in a bit of code to detect this and to over-ride whatever might otherwise have been the quote with And the other way round and set about testing it. Ive been through literally dozens of full 90 calls watching for the occurrence of a reversed number, spent a few hours doing it, and not once has it occurred which is to say the least, unusual.
So, Im wondering about the Rand Function, could it be that it isnt possible for a reversed number to be selected? Just so you know, I randomly pre-select the order of all 90 numbers, I fill each of the 90 elements of an array with a random number first checking that the number selected hasnt already been stored, if it has, I just get the next random number (and check that too of course), but I cant see how that could prevent reversed numbers being selected, especially in light of the fact that frequently it's not the 'next' number that's used.
When Calling New On An Object - Can The Object Being Created Refer Back To Its Caller
Nov 11, 2010I hope the question makes sense, anyways. I'm looking to know if in VB.NET, when we call an object's constructor, is there some kind of a reference that points back to the caller? I'm interested because of a corner case where I want the object being created to first be able to validate the existence of some data in the caller before it allows itself to be created. If this validation fails, I plan on throwing an exception. This corner case will never happen at runtime unless the object being created is used improperly by a programmer. The object being created is not inheriting the object I want it to validate, so I can't do anything with the MyBase qualifier.
It's bit of a "future-proofing" issue that I have a (bad) habit of doing. Not critical -- I can always leave stern comments behind as a last resort. Wanted to know if this was possible.
Debugging Exception On Invocation Target Instead Of Invocation Caller?
Jan 28, 2010When a delegate method throws an unhandled exception, that exception is usually trapped at the level of invocation (eg. Delegate.Invoke()) - you get a System.Reflection.TargetInvocationException...
However, when debugging classes utilizing a lot of threading/invoation, it would be helpful to be able trap the exception in the target method i.e. the faulty code, and since Microsofts BackgroundWorker (exceptions thrown in DoWork()) is able to do it, why can't I???

Bug In Serialport Control When Using E - 8 - 2 Parameters?
Jun 16, 2011We have been debugging a problem with serial communications with an embedded device on 115200 baud, Even parity, 8 databits and 2 stopbits. The problem: a lot of extra 0x00 are sometimes received from the serialport.
1) We build a real basic sample program that only handles the data exchange. It was completely build according the serial-port-vb.doc from msdn. It was build in vb.net 2010. So this was the most basic setup possible on the PC side. This simple tool clearly shows the datareceived event spitting out extra bytes.
2) We used a scope to look at the hardware bits/levels. No problems / differences seen between good and bad messages. No extra bytes visible that the serialport event send to our programm.
3) We tapped the serial communication and received no wrong data on the tapping system but still on the .net tool. Again the serialport datareceived event gave us many extra 0x00 bytes.
So our only possible conclusion is that there is a problem in the serialport component from .net. My question: Are there any know issues? Can I get in contact with a microsoft engineer?
