I'm trying to making an auto-responding program for different Instant Messaging chat programs, like MSN or XFire.I don't know if it's possible to do this in Visual Basic. If not, feel free to post a solution in C# or C++ too.

I found an example of a simple irc client, but I'm really confused about how it sends data back to the irc server. In the example, this is the code used to respond to the server's PING request. it lies in the onDataArrival event of a sockets client:[Code]
However with this simplified code, as soon as it tries to respond to the PING request it is disconnected from the irc server with the reason "Excess Flood". So I was hoping someone could explain to me the difference between the pretty complicated method and my simplified one which doesn't work.

I'm using a modified version of John's Message server, instead of passing a string I am passing a serializable object called "DataClass".This is my modified Read sub to process data that gets sent from the client to the server:
vb.net
Protected Overrides Sub Read(ByVal ar As IAsyncResult)
Dim asyncState = DirectCast(ar.AsyncState, ReadAsyncState)
Dim buffer = asyncState.Buffer
Dim client = asyncState.Client
Dim host = Me.clients(client)

The message is received fine when they aren't in quick succession, however I tested it by sending like 1000 messages almost instantaneously and it only processed about 2. Obviously this isn't acceptable, but I am unsure how to properly implement some type of queue that will ensure all backlogged messages will get processed.
Previously I asked about sending emails. And now, I have a related question.How to use a preset message in the email ?
Dim strMessage As String = "Hi [USERNAME]..! You have not paid your due amount of Rs. [DUEAMOUNT]. The last date for payment is [LASTDATE]. I want it to be in such a way that, when a button is clicked, all users with pending amount will be selected (from db) and the above preset message is formatted with each user's USERNAME, DUEAMOUNT & LASTDATE, and finally added it to another table in my db.
Presently my idea is to use a SELECT query for getting all the pending users and then loop through each user (record) and add the preset message to a separate table (this table contains all drafted messages which will be then sent to the recipients), by replacing the USERNAME, DUEAMOUNT & LASTDATE using the Replace function.

View 12 RepliesI have an app that I'm using Form2 to display informaitonal messages without having the user to press the OK button. I DIM form2 as a new form as a global and then add a lable to it on the fly and then control it's appearance with a timer. This all works great providing the main form is being displayed however I can't make Form2 show up if the main form is minimized or hidden. I can get around this a bit by keeping the main form maximized but change it's Opacity to zero but once I do that I have no idea how to return the Opacity back to normal when I do want to see the form. Anyone have any ideas on how to make Form2 display if the main from is minimzed or how to control the Opacity of the main form so I can return things to normal? I was thinking that there might be something I could do with hovering over or clicking on the icon in the taskbar but I don't know what that event might be.
View 5 RepliesI am capturing a few system command messages (namely minimize/maximize/restore). Inside the WndProc override I am trying to change the form's Me.ShowInTaskbar value but it is causing weird behavior in that minimization and restoration does not occur properly.Can anyone think of a reason why changing this property would interfere with this? The reason I don't really want to post code is because duplicating the effect takes a bit of code/setup. My initial thought was that changing the property's value is somehow sending another windows message and canceling the one I am currently manipulating. I realize this is a little vague but it's a shot in the dark.
View 1 RepliesObjects whose Properties are observed for changes must implement the System.ComponentModel.INotifyPropertyChanged event to alert their WPF-element observers that a change has occurred.
If I have a Visual Basic Module whose Properties I wish to have observed by a WPF element, how should I go about routing the Properties of that Module through to the WPF, considering that Modules cannot, themselves, implement Interfaces?
EDIT: Modules are Static classes, for you C# readers, IIRC.
I have a datagrid and I want to delete selected row from that grid. It is working fine upto this. but I want to add some advance functioning with msgbox YES-No buttons. If user select some row and click on delete button, A msgbox with YES/No options appears. If user clicks YES, row should be deleted but if No is clicked then that row should not be deleted.

The idea with System.IntPtr is to represent an integer whose width in bits correspond to the size of a pointer in the hardware and operating system that the CLR is running in, it's platform specific in other words. It supports 32-bit and 64-bit architectures only.This is a legacy from old-style C API's where pointers and ints were frequently treated as interchangeable. The Win32 API has many such parameters, where the width varies with the underlying architecture thus the mess with porting of code from 32-bit to 64-bit (we already did this once when going from 16-bit to 32-bit, funny how we never learn...).In practice, as is mentioned in other responses, it can be used to hold unmanaged resource handles and pointers etc that stem from the underlying Win32 functions. It can also be used to hold integers of the natural size for current platform. You can also use IntPtr.Size to dtermine the size of a pointer on the current platform.SO when you explain this to a child ;) this would be used to let program's flow at the same speed at diffrent kinds of operating systems?

Which works and prints out all output from the commandline program. However at some point the commandline program ask for user interaction, eg: Type a number (1/2/3/4):But the commandline program stops after this. I suspect this is because it doesn't receive a valid option.Is there a way to capture when the commandline program wants user interaction and hold the reading of the stream to be able to enable the user to input something?

I have a server making a head request to a database dump I've created. The remote server does this to make sure that it's not using excessive bandwidth when not necessary.However, due to some other circumstances outside my control this causes the script to be hit twice: once for the head request, and then another time to download the data.
What I'd like is to have the script I've written detect the head request, send back a couple of headers (e.g. last modified is right now, filesize different than before), and exit. Is there a way to do this?

View 1 RepliesI have a class, BaseSample, that uses another class, MainData, as one of its fields:
Protected _sampleData As MainData
Public Property SampleData() As MainData
Get
[code]....
MainData in turn has a collection of a class, ProcessData, as a field and ProcessData has a collection of a class, Measurement, as a field. I.e.:
MainData
|- IEnumerable (Of ProcessData)
|- IEnumerable (Of Measurement)
These classes are entities in a LINQ to SQL file. In the Measurement class, I raise the PropertyChanged event when the CrucibleOxidizedMass property changes:
Private Sub OnCrucibleOxidizedMassChanged()
RaiseEvent PropertyChanged(Me, New ComponentModel.PropertyChangedEventArgs("CrucibleOxidizedMass"))
End Sub
In the BaseSample class, I want to respond to the CrucibleOxidizedMass PropertyChanged event in any of the descendent Measurment instances. How would I do this?
