Show Messagebox/play Sound When System Time = Time Displayed In Listview?
Nov 13, 2010
Basically i'm trying making a task manager program for myself. I want to know how I can display a message box and or play a sound when system time = time displayed in listview. I have used a dropdown box for the user to select which option they would like to select - sound or message box to popup. The data for the task will be stored in a listview box. I want it so that when the date and the time is = to the date and time set for the reminder the action will follow.Here is my code so far:
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim notext As String = ""
If TextBox1.Text = notext Then[code]....

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.

How I can use a messagebox to show for a specific amount of time only? So if I place this in maintimer, MessageBox will show and will auto close and I set how long it must display for. If messagebox is up, then Timer is paused. I did research around these lines but couldn't find what I'm looking for.

Hey guys, I'm a new guy in VB.NET. I am proposing my final year project a title called music studio. My version of music studio is like real music video where we can play many sound at any time. For example, the application that I want to build can create many button and also add an audio along with it. And then, when we hit the 1st button, it play 1st audio. while 1st audio play, we also can hit 2nd button and 2nd audio is playing. for example, 1st audio is sound of man walking, and then 2nd audio is the sound of glass break. lastly 3rd sound sound of police siren play. Is it cool? so, my question is, is it possible the I can build an application by using VB.NET?

The idea with this form is to add the futures which is calculated when the button is pushed but I need the list to update every time and show the values each time to which the previous value is added to the new calculation, e.g. of what it should look like in listbox:
Year 1: $1,290.93
Year 2: $2,724.32
Year 3: $4,350.76
etc....
I have been working on this a while and I am at a standstill, I was given a function to clear the form everytime it calculates but I don't know how to implement it, I am new to VB. Here is what I have so far:
Public Class frmFutureValue
Private Sub btnCalculate_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles btnCalculate.Click
[code]....

I'm using
Days = Dat2.Subtract(Dat1).Days
where
Dat2 = today
Dat1 = installed date
to trace the days of a program installed in user's computer.However, the user can changes the system time of his computer to a advancing date. How can I get a SNTP time from internet to solve this problem?

The Now() function in VB.NET returns date and time which is different from the system time that I see on the right-bottom on the notification bar. It is 15 hours slower than the system time. Has anyone ever met this problem? I'm using .NET 2.0.

I have background sound loop with the My.Computer.Audio and it works fine. I want to play another sound (like a beep) when desired without stopping the background sound. Several examples I have found don't seem to work. I am in VB.NET 2008 Professional.

Is it possible to play two or more sounds at the same time (i.e., one plays in the background and one plays a sound effect) and if so, how can I do this? I am having problems because it is cancelling one of the sounds out when the other starts.

I have an ASP.NET application with a SQL Server back end. I am storing all my dates in UTC format and doing the appropriate conversions to the local time zone of the browser viewing it. One of the pages asks for a start date and end date (no times).
I am taking the start date and setting the time to 00:00:00 hours (midnight) and I'm taking the End time and adding a time of 23:59:59, so that the date range covers the whole day. Now what I'm trying to do is do a SQL query to do a search for records in this date range. The problem is, the data in SQL is in UTC time and the user is typing their dates and times in their local date and times. My quickest solution was to convert the date and time to UTC, then search the records. However, by doing this, I am to believe ASP.NET converts the given time and date to UTC based on the server time zone. How can I convert a date and time to UTC time based on the time zone of the user?

I do get that I'm going to need to "thread" them separately, but I've been unsuccessful so far.
I get the audio clips to play, but when one starts, the other stops.
This is code that's playing the audio, derived from examples in preior postings[code]...

How does one check to see if the system time is equal or not equal to a specific time? So, say I want to perform an action if your system time is between 6pm and 6am. Or something similar?

I'm using VB 2010 Express with two instance of AxWindowsMediaPlayer in order to sync two videos (the videos are of the same thing but from two camera angles). Because the videos were started at slightly different times I've manually set the start time of each one using the following
AxWindowsMediaPlayer1.Ctlcontrols.currentPosition = 314.5093196
AxWindowsMediaPlayer2.Ctlcontrols.currentPosition = 237.1639908
The problem I'm having is that whilst the WMP clock initially displays the above times in each AxWindowsMediaPlayer, when I play the videos each starts a few seconds out from the stated currentPositions.
The video files are around 300MB each and when testing with smaller video files the problem does not seem to happen. I'm guessing the large file size is causing some delay and hence causing the problem.

I found some great code on capturing webcam images but the problem is the client PC will need to initiate the communication to this server (click Connect to server IP). This is like 2 way communication.How can i do something like this (door Kiosk system):when a visitor press a button on the LCD that come along a web cam (this will be the server), it will send the signal the client PC that is installed with the application i've created (window form) and pop up the images to the client PC (more like a 1 way communication). This image is captured through the web cam on the server to capture the visotor's image waiting outside of the door. How to do this?I'm really stuck as i'm not familiar with window API programming yet.
1) how to do the mentioned 1 way communication? possible in .NET?
2) how to make my application to be at the tray icon just next to the time displayed on the right bottom corner of the task bar? When a visitor press a button o the server, it will pop up a window form on the client PC showing the image captured via the server's webcam outside of the door.

I have the following
Public Class Form1
Private GIFAnim As Image = Image.FromFile("c:cointosscointoss_ani.gif")
Private frames As Integer
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
[CODE]...
Now I would like to put a wait in after the line:
frames = GIFAnim.GetFrameCount(Imaging.FrameDimension.Time)
ImageAnimator.Animate(GIFAnim, AddressOf paintFrame)
This is so that the animation has time to play and stop and then the rest of the code will display the other picture and the numbers. Is this possible? I tried timer and sleep but I cant get them to work.

I have a section of code in which I want to display a messagebox after a form is displayed... as the form loads. me.show messagebox.show If I don't use me.show first, the messagebox appears before the form is displayed. If I do use me.show first, the form appears, but is not always complete before the messagebox appears. Is there an easy way to poll the form to see if it is done displaying without using a timer?

I have the following code Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick Dim mesaj As New Integer
[Code]...
The timer interval is set to 5000(5 seconds), but every time when the timer is ticking the msgbox appears on screen but the in the file msg.txt is writting once. So, The timer check if that unic is different from unic1, and if is different shows up a msg box, and it's writting the new line in msg.txt, but on next timer tick, even if the unic and unic1 are equals the msgbox shows up anyway, but it's more interesting because it doesn't write again in file, only shows up the msgbox. I don't understand this.

I have a parent form, which can lanch a dialog box. A wrong selection in the box launches a message box with an error message. When the message box pops up, the dialog box disappears, so the messagebox is sitting on top of the parent form.Once the user clicks "OK" in the messagebox, the box disappears, and only the parent form remains.How do I make it so that the dialog box remains when the messagebox is displayed? And also, I want the dialog box to remain when the user closes the message box. The user should have the option to make the right selection in the dialogbox once the messagebox disappears.I tried to hunt for a property for the dialog box to achieve this, but couldn't find any.
Here is the code in the parent form to lauch the dialog box, and to also launch the messagebox, when the user has made a selection in the dialogbox:[code]Am I having this problem because all the code to launch the dialog and message boxes reside in the parent form? If I put the code to launch the messagebox in the dialog box, would that make the dialog box persistent when the messagebox is launched? I am putting all the code in the parent form because it can process the DialogResult.
