Checking If Start And End Time Is Overlapping?
Sep 3, 2010
I am part of a group writing a program for scheduling purposes. In the program I must check to see if times are overlapping.Say an Instructor is in class 1/1/2011 3:00:00pm to 1/1/2011 4:00:00pm receive the Instructor and 1/1/2011 3:10:00pm to 1/1/2011 4:50:00pmThis should return True the instructor is overlapped.Of course the other side would be if the time started/ended before or after the original class.I've tried many different combination's of if statements similar to:
If (begTime <= s.BegTime AndAlso endTime <= s.BegTime) Or (begTime >= s.EndTime AndAlso endTime >= s.EndTime) Then
End If
[code].....

I want to start the time in one user only because when i add a user in my listview and click the start button both of them start their time. how can only start one user only? and when i select the other user and start their time the first one that i start is continues deducting a time.
This is my code:
Public Class Form1
Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
With Timer1
.Interval = 1000 '// set interval to 1,000, which is 1 second.

I'm making a new program so I won't be able to post my code here yet.
But I wanted to ask you fine folk how I can check if a program is running for the first time.
[code...]
Just start the program normally and when they click the menubar ask for the password they set in the first time
if it's a little iffy on my side but I just started this project and I've only made the GUI and I have no idea what so ever how to do this.

I have a program which have to play a sound at a specific time in each day.Currently I made a timer with 450 interval and I put a code in it which check if datetime.now = mytime then it will play the sound.(the program runs in background)
It is working but the problem is that sometimes it doesn't play the sound. I think I didn't used a proper way to this.I have even tried checking datetime.now.hour & .minute & .second with mytime to make sure it does play it at the right time But I don't know why the timer sometimes miss it and the play sound won't be run.

I have been trying to check if a user has input a specific time format into a textbox.For example
1- User enters time in hhmm format
2- Checks the input
3- If wrong, MessageBox.Show("Need hh:mm time format")
I have only used IF statement with IsNumeric to check for number input but was unsuccessful with various attempts I can think of for checking a time format as I need Option Strict On and have the following error: Option Strict On disallows implicit conversions from 'String' to 'Date'.Is there a way to like check if the hh:mm has the ":" separator too?

FIRST = arguments checked against each other
SECOND = arguments checked against each other but are irregardless of the FIRST arguments.
If (FIRST and (FIRST or (FIRST and FIRST))) OR (SECOND or (SECOND or SECOND or (SECOND and (SECOND or SECOND)))) then As the program processes this line over a million times during the execution, only FIRST or SECOND section is needed during an execution, never both. How do I make the program use only the section that's needed for the current execution instead of checking every argument every time? Is there a way to turn a string into an argument list for an IF...THEN statement? [code]

I have written my first service that checks the status of servers. I have used the statement System.Threading.Thread.Sleep(86400000), so that the service will run, then sleep for 24hrs before running again.
My problem is i want the service to run at 7am every morning, when i install and start the service it will run from the time i start it. I dont have access to required computer at 7am.
Is there a way of setting the service to run at 7am on the first run? Was thinking a Loop, or timer but dont want to be eating resources up while it is not necessary.

how to start a VB.NET program at a specific time of the day, but I simply cannot find it. I've found an example that shuts down the computer at a specific time of the day, but having no experience with the Timer function, I wouldn't know where to start when hacking the code.As an example, I'd like the program to run at say 2:00PM and display a message. The displaying the message won't be hard (MessageBox.Show("Stuff")), it's just the starting .

It works but it makes the program crash for 4-9 seconds.I was thinking of downloading the file more slowly or using Threading()

Knowing the hWnd and the Title of all the desktop windows, I whould like to order them by start time order (them order on the task bar)In your opinion is there an API that gives those data? I can't use the Process.StartTime property because many of these windows have the Process.MainWindowTitle = "" and Process.MainWindowHandle = 0

When I setup the event using DDay.ical I can successfully send the events to a user's outlook. The problem arises when multiple events are setup at the same time. When this happens all emails are updates to the original task, not new tasks.
I tried adding a name to the event using the .Name property, which results in the event email being an unsupported calendar invite.

I have made my application to start automaticly when windows start (registry ../currentversion/run/appname + path). In this mode the application start minimized and an little icon appear in the notification icon area. With this icon you can maximize the app or exit it.If you exit the app and start it again using the Menu (Start/programs etc) than the application start in minimized mode (and in this case I would like to have it in normal mode) because the setting autostart is still true.Is there a way you can detect when the application start when windows startup using the above registry or when people click on an icon in the programs menu (or desktop)?

Vb.net For each currentFarm in ......
If urlQueue.Count > 0 Then
Debug.Assert(currentFarm.isBusy = False)
Debug.Assert(currentFarm.WebClient.IsBusy = False)
[CODE]...
The commented code won't work. That's because by the time the thread start, the variable currentFarm have changed. So I create a new function and cache the currentFarm in the function parameter. No there will be a cache of currentFarm address (object is always a pointer) on a stack and that address is the one being passed to the System.Threading.Thread constructor.

I have a map of the world which is set as a background image of a form. I then have individual countries in red and green which appear based on the result of a ping request. So if the IP address pings ok the country turns green, if the ping fails then it turns red. The individual red and green countries are picture boxes with transparent backgrounds.The problem is that, for example, America and Mexico overlap each other and where they overlap it just show the background of the form. Can I have the picture boxes overlap but show each other underneath?See the image below for what I mean as it's not easy to say what I mean [URL]

in a program I'm writing I'm creating some objects with a start date (with a datepicker) and an end date (also with a datepicker).
Now I need to check if this object's date range overlaps with any other object's date range stored in the database. If it does I can't save it in the database but if it doesn't I can.

I usually can find anything I need on google, but this isn't the case this time. I have a com object that is a display control, it displays images from another software that are retrieved from a camera. I am trying to overlay graphics on this image for reference to an operator. I have found how make a picture box image transparent but not over another object. The images are PNG and are set to transparent.

I have a vb app that I completed a few months ago and it has been working as it should.I have blurred out part of the image for business reasons. But you can see in the second picture in the top left it has the bottom right of the background overlapping in it.
I copied the exe file over to another computer and Im having an issue where the program will load and look OK but then after about 5 seconds part of the background will show up in the top left corner. Im not sure why. It is the exact same exe on the other computer but it only does it on this computer.I have attached images below so you can see what Im talking about.Im not sure if its a program issue or a setting on my computer.

I have two grids inside a TabItem and in the code-behind I want to be able to add controls to both grids and have all the controls visible at run-time. Currently at run-time the controls added to "Grid3" are not visible while he controls added to "Grid4" are visible.The overlapping grids have the same rows but a different set of columns.I'm trying to do this with two grids so that I can vary the number of controls I can add per row in the code-behind by adding the controls to one of the two grids.Here's the XML:
<Grid Name="TabControlGrid" Margin="20,171,0,70">
<TabControl >
<TabItem Header="Tab1" >[code].....
The controls in the XML are just place holders for the controls I am adding to the grids in the code-behind.
