i am looking for some .net based library/piece of code to implement task/activity scheduling like microsoft project scheduling in following cases...
Finish to Start
Finish to Finish
Start to Finish
[code]....
is it guaranted that a task A started before TaskB will be completed before task B assuming the task do the same level of operatons?or in other words is there a chance that a task B will finish before tast A in the assumption that the task calls the same procedure?
View 4 RepliesDoes 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.

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 1 RepliesConsider we have 3-tier app and have got three projects named P1, P2, P3.
Dependency: P1(Data) << P2(Business Logic) << P3(Presentation)
P2 has got a base class X that was inherited in an other class Y in P2. So, we add the ref P1 to P2. However, P3 uses P2.Y and doesn't use P1.X directly.
To do this we have to add ref P2 to P3. But there is a difference between VB and C#.
In VB, we add ref P2 only to P3. P2 uses P1 but it doesn't matters for P3. We don't need to add ref P1 to P3. This is enough!
But, in C#, we have to add ref P1 and P2 both to P3 even if the P3 doesn't use P1.X . If you don't add ref A to C you get the error below:
The type 'P1.X' is defined in an assembly that is not referenced. You must add a reference to assembly 'P1, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.
Why must we add two projects in C#?

All files that starts by IM2_ are the files what i want to get the path.

I 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>
<FormTitle>frmCustomer</FormTitle>

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.
In ASP.Net Web Forms there are cases that I've come across that create order dependent code. As an obvious code smell I'm looking for solutions to solve this problem.
A pseudo-code example would be: Calling Code :: Page.aspx
protected void Page_Load(...) {
var control = LoadControl("ControlX.ascx");
// Ugly since the control's constructor is not used by LoadControl
control.SetDependencies(...);
[Code]...
LoadControl has two signatures, the one used above accepts a string for the control classes physical location and correctly creates the child controls. Whereas the second signature accepts the control class as a class type, and any parameters for the constructor, however the child controls are not created as detailed in TRULY Understanding Dynamic Controls.
So how can I eliminate this order dependency in the cleanest way? My first thought is that if I dynamically created the child controls in ControlX, but then that can be cumbersome for larger controls.
I recently added hsProgressbar.dll to my Program, it worked fine, but then I decided to remove it from my Computer and also remove it from the references...however..the Warning is still there? How can I completely remove it, so that I don't get the error anymore?
