I want to be able to intercept a print request and then check whether the current user of the computer has enough credit to print. So once the request is intercepted i want to check the total number of pages requested and check against a database how many pages this user is allocated to print, if the total number to print exceeds the number in the database then cancel the print job and notify the user

View 3 RepliesI wish to intercept print jobs, read who they are from etc, and then only print them, if the program wants to.

View 4 RepliesI have recently started using Request("key") instead of Request.QueryString("key") to access my querystring values. However I have read that:
'Gets the specified object from the System.Web.HttpRequest.Cookies, System.Web.HttpRequest.Form, System.Web.HttpRequest.QueryString, System.Web.HttpRequest.ServerVariables'
Therefore, if I have a querystring key and cookie key which are the same, which value is returned?
I have two arrays which I am graphing. I want to use VB to calculate the slope and intercept of the resulting graph. I'm using the Analysis.Math function of measurement studio. Here is what I have so far.

I play a midi file using this simple win32 api call:
MidiMsg = "open " & c_midiFile & " type sequencer alias mid1 notify"

ret = mciSendString("play mid1", "", 0, Form1.Handle)
Callback message MM_MCINOTIFY has a value of &H3B9 (found it using "spy++")I have to know when this message (MM_MCINOTIFY) is fired and read his parameters. In an old version of code I've written years ago in VB6 i had to use CallWindowProc and SetWindowLong win32 api, but now in VS2005 i cannot get it to work.Still I have to try with unmanaged code or are there any other ways to do this in vb .net?
Is there a way to intercept POST data like HTTPAnalyzer?Can I make a call to send the data, see how it's formatted but actually block the connection if I know where it's coming from?
My goal here is to replicate the sending of an email through an SMTP server.
This is not a programming question but a physics one.I was wondering if anyone has a link that good give me the math for two objects: one moving and the other intercepting. Specifically, I need to determine the vectors of the pursuing object when given the vectors of the object he is trying to pursue.This is classic video game programming and in my instance it's supposed to be a football player running with the ball being chased by a tackler.The code I have now determines where the tackler should go at one particular instant, but does not project where he should be in order to lead the target.What happens is the tackler runs behind the ball carrier - he doesn't cut him off.It's like if a QB throws the ball to where his receiver is instead of in front of him; when the ball arrives the receiver is long gone.
View 2 RepliesI am looking for a way to possibly intercept the point that a file is being accessed on a network share. Specifically before it is determined whether the user has access to the file or not.The goal will be to grant access to that file if the file request is coming from a specific process and that user currently does not have access.

When a user clicks on the little red "x" a.k.a. the form close button on the form command bar, what even is activated besides FormClosed()
I know FormClosing() is called, but I cannot really stop the form from closing after my code is run. I want to be able to show a messagebox that asks if the user wants to exit the form or not. Obviously if they click no, I want the form to stay open, how would I do this?
This may seem complicated but it's a somewhat basic concept, just probably a complicated execution, I am trying to create a program that will allow you to basically "IM" between computers on a LAN network. That's the concept, I plan on doing this by generating .bat files, executing them and printing the last few messages sent in a label, the big problem I have is receiving messages, I have no idea whatsoever how to even go about finding out how to take the messages received from the messenger service and print them into the label, any ideas?EDIT: This is in VB.Net 2008
View 5 RepliesFor my webbrowser application I would like to have a separate form to display online pdf files.Does anyone know how I would check to see if a clicked page link points to a pdf file and if so open form3 and load the file into the pdf reader component (pdfread) without causing the webbrowser to navigate to the link, this always seems to open the pdf file in a new instance of internet explorer.
I realise that to load the file into the pdf reader the code would be
pdfread.loadfile(whatever file)Hope I've explained this properly.
Not an "ad" popup, but a prompt or a "yes/no" question.
View 5 RepliesI've adapted the code from this link to use the WinXP on-screen keyboard (osk) for a touch-screen application written in VB.NET v3.5. The osk fills the bottom half of screen etc. and behaves fine except for one little quirk. If the user clicks or taps anywhere on the 'background' area behind/between the virtual keys (within the main osk window), the color of the area changes to that of the keys when any further key subsequently gets focus. The outline of all keys is then lost because they are visually merged into the osk window background. The osk must then be terminated and re-launched to remove the confusing appearance.
This behaviour only occurs when the osk window is set to the child style (i.e. when the menu is hidden), using the SetWindowLong P/Invoke function - e.g.
SetWindowLong(OskProcess.MainWindowHandle, GWL_STYLE, WS_CHILD)
It's as if the entire area behind the keys is being treated as another key when tapped/clicked, whereupon its color is 'restored' after losing focus.Is there any way to intercept and somehow override the focus event of this osk background area?

I'm wondering if it's possible to create a listener type application that would monitor webaddresses that the user attempts to go to. And can then either block or redirect the browser to another website. Purpose: I know this seems to sound a little weird but what I'm attempting to do is a NetNanny type application that can run on the user's PC and the allow, prevent, rewrite (would look for particular keywords and rewrite them "words I wouldn't want my 7yr old seeing or reading), or redirect to other webpages. I would also like to be able to handle both IE and Firefox browser with this one application.

My Request.Form keys are all prefixed with ctl00$container name$ and then the key I want.How can I get the regular key name working?
Visual example from the immediate window:I want to use:
? request.Form.Item("stationIdea")
but it won't work because the key is:
ctl00$content_innovation_body$stationIdea
as retrieved by
? request.Form.Keys("4")
so only this works:
? request.Form("ctl00$content_innovation_body$stationIdea")
i have a task to create a TCP Server (a program that is listening on its network card interfaces for incoming data stream).I have search on the internet and i found that i can use two methods : Socket or TCPListener class.I have created an example for Socket class, but i wondering how could i test it? I need to check that if another computer in the network send some string data to the listener computer , then this message should be displayed.Here is the example from microsoft that i am using for TCP Server using Socket:
Public Shared Sub Main()
' Data buffer for incoming data.
Dim data = nothingc[code]....
But it does not work because of the PORT setting.If in the TCP Server i have "Dim localEndPoint As New IPEndPoint(ipAddress, 0)" the client crashes, but if i change the port from any (0) to 11000 for example,the client works fine.Do you know why?
Later edit2:Maybe i should have started with this question:Which method is recommended for my scope?asynchronous or synchronous method ?
I am developing a computer application designed to monitor the network and CPU statistics on a computer remotely. The monitored computer would have my program installed and the monitoring computer would display, in a form, the information being sent from the remote client.The application does not send any information regarding packets, user names, passwords, etc. It is solely meant for monitoring CPU performance and Network resources remotely.
What would be the best method to send this information over to my host machine?I am programing in Visual Studio 2008 on windows XP. The client machine is also XP. I know this sounds a little shady, but it is required for my little business (http://www.iquorum.net) to monitor what and when something happens on our machines when I and my employees are away.
