I am using VB.NET 2005 and am looking for a code example that can pause all Windows applications the same way changing desktop themes does. I want all background applications to fade to black and white while allowing the foreground application to continue normally.
View 4 RepliesIs it possible to prevent the pause or gap when playing audio from a windows media playlist in VS 2008?
Or is there another method of playing .wav or .mp3 files without pauses or gaps inbetween each other?
1) Why the pause button and also the pause command does not exist in VB 2010 Express?
2) I have some solutions under 2010. In 2 or 3, while debugging, I can change instructions without restarting the application. In others, I cannot change anything (Is like readonly), Looking in 'My Applications', Tab 'Debug', Option 'Configuration' I can choose several Options. In the applications I can debug, the default is 'Active (Debug)'; in the others is 'Active (Release)'. If I change the options, the word 'Active' remains attached to the original option.
I am actually designing a simple media player. Here are all the buttons I have
1)play
2)pause
3)stop
4)next track
5)previous track
6)fast forward
7)fast rewind
8)repeat playlist

In all of these only play, stop and pause work everything else isn't working. tried lot of codes and even forms nothing works ..
I have an app that I'm debugging and I need to pause it by clicking on a "pause" button in the development environment. I don't want to stop it programmatically, just manually to check what it is doing. I know this should be simple but I can't find a pause button anywhere on the toolbar.
View 4 RepliesI am trying to make a start and pause button (and hence continue) to start, pause, and continue my program. The start button works but the pause button does not. Can someone look at my code and see what the pause button needs to do to pause the program? I am using VB 2005. Here is my code.

Does anyone know of a way to detect recent activity in a VB.net windows forms application?
We have a retail store where users share floor computers, the application will be on each machine and require a log in before use. I am trying to find a way to automatically close the application if it has been idle for lets say 10 minutes.
I guess I could do something similar with the current windows log on session - set a gp that logs the user out after 10 minutes of inactivity - but if there is an easy, non memory intensive way to do it in vb.net i would rather use that method
I'm in the process of creating a tool that allows users to download stuff from a LAN server. The progress of the download is now being shown as a progress bar that performs a step each time a file is downloaded.
But if the file is a large file (Let's say a 2 GB file) it'll take a while before the progressbar performs a step and the user might think the tool froze up and close it. Now i'm wondering if there's a way to show the activity on the NICs installed. Something like when you open up task manager and go to the "Networking" tab. Showing it as a graph would be awesome or just a percentage is good aswell I have NO idea where I should start looking..

I'm developing a utility that will look through Active Directory and find anyone that hasn't logged in 90, 120, 180, 365 days. Between what I know and researched on here I've pieced together code that works part of the time. When I LDAP a container with approx 2000 or less user objects it will work, but when I LDAP the entire directory it loops through approx 60,000 user objects.Part of the way through it returns the following warning:
ContextSwitchDeadlock was detected Message: The CLR has been unable to transition from COM context 0x4dbc88 to COM context 0x4dbdf8 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during long running operations.
When I tell it to continue it goes a little further before finally hitting a OutOfMemory Exception:

I'm looking for a way to monitor drive activity using Visual Basic 2008. I want to create a small utility to simulate an LED in the system tray for drive read/write activity. I've found several such utilities that do this, but they all lack one thing or another, or they are over bloated with stuff I don't want or need, etc. I want to write my own so it will be like I want it. To get started, I need to know how to monitor drive activity.

View 1 RepliesI want to have a VB.Net windows application that monitors the page, and when it detects certain events it triggers some actions based on the data in the page. I've been searching like crazy for some mechanism to "hook" into the browser and hopefully inspect the messages transmitted for the application to know how to react.I've seen the SHDocVw COM object, which comes very close. But when I use the BeforeNavigate2 event, it only seems to fire for GETs, and once I'm on the page where the information is displayed/refreshed the event is not raised.Short of reverse engineering the page, or having to write some kind of proxy...is there a good way to do this in VB.Net?

View 3 RepliesI have a winform which allows people to edit data from a database, to simplify things assume there is a Customer table in database with 3 fields - Name, City, Country. Through winform(s) people can Add/Edit/Delete customers.For each of these actions we need to save:
What the field names are (Name,City,Country in this case)What the field values were before they were modified What the field values are after they are modified.If the action is Add or Delete then 2 and 3 will be the same.I have already implemented this using XMLSerialisation (but not using any of the design patterns) and my XML output looks like this.
<?xml version="1.0" encoding="utf-8"?>
<ActivityItem xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<UserID>26</UserID>

The solution can handle different areas of the system with different number of fields (i.e the same thing works when you are modifying Products for instance).is there a well defined design pattern to deal with this kind of behavior?

Well im getting a error from my antyvirus that my file has been doing suspicuous activity and i dont know how to correct it.
For refrence i have Norton 360 antivirus... 2010
there is any event or way to detect activity in an form or project?in the form and all the child controls.
mainly mouse clicks (not mousemove) and key press.
for example, if the form have not activity in the lasts 10 minutes, do something.
I would like to try and implement a feature wherby once you have logged into an application (straightforward winforms application) and had your credetials verified the application would then force you to log on again if no activity had been detected in the application for a certain number of minutes. In essence I want to provide some extra security for those occasions when users get up and wander away from their machines for prolonged periods.
I have all the logic for logging into the application, it's just the checking for no activity over a given period and then forcing the user to log back in again that I'm not having much luck with.
I want to create a custom form (in visual basic .NET) that will stop other process responsiveness until the form is acknowledged. It would be a nice bonus if I can add a beep when trying to access the main program UI while this form is displayed as well (like how a messagebox does).
