I want to create a Timer such that I can reset the time to say 00:00:00 (hrs:mins:sec) and be able to stop, reset and start the timer as needed. I have actually created one from the scratch but it seems like it is long on code. Any ideas on how best to do this?Only performance counts!

View 13 RepliesWindows resets the IDLE time every time the user touches the keyboard or the mouse. My application needs to reset the IDLE time at specific moments, but how to do this programmatically.
The following does NOT reset the IDLE time using VB, C# or QT4.
- Programmatic mouse movement / click.
- Programmatic keystroke.
Somehow Windows knows these actions are simulated. How can I reset the IDLE time?
I have a small dataset which has most of its schema defined at design time, but I add a few columns to one of its tables at runtime. My problem is how do I reset those changes? he dataset is not linked to any datasource. It just has its own table which I "manually" populate. The static columns have been added to the datatable at design time. However, I add a few columns as runtime based on a list of categories. Like this:
[Code]....
The dataset is used in a small dialog that pops up within my application. I add the dynamic columns when the dialog is opened by using the Load event. Everything works great the first time. But if you close the dialog and reopen it, there are problems. My startup routine tries adding the dynamic columns again, but an error is thrown saying the column already exists. I have tried a lot of things and did some reading but I can't figure out a way to reset the dataset when the dialog is closed. The only solution is to close the whole application and reopen it. I have tried the following in the Leave event of the dialog form:

How do I reset My.Settings at run time to the initial default values. I want to do this after the app has been running and the user may have save changed settings. The intention is to reset evering to 'factory defaults' as opposed to the last saved value as done by 'settings.reload'.For example in the property below , I want to restore to the value to '90' as given in the default value. I want to do this for all settings.[code]...

But ofc Me.controls isn't gonna get involved with the stuff in the groupbox.
I've done what I thought was a lot of work with DateTime and Timespan but what I am trying to do now I cannot figure out. It seems simple enough but I can't think of the code I need to make it work >.<
Currently I am using a timer to tic on 1000ms to count down a timespan. However, what I would like to do is set a timer for 30 minutes. I would like to display the minutes:seconds of the timer on a label and perform actions when the minutes and seconds are specific values, say minutes = 5 AND seconds = 0 to perform an action when the timer reaches 5 minutes exactly.
My goal is to have a 30 minute timer that performs actions at specific times, then when the timer reaches 0:00 it restarts at 30:00 This seems like such a simple task but I cannot for the life of me figure out where to start.

View 5 RepliesOk, so I am building my own program to control a video player I have through telnet, I have everything else working except one thing.I have a reset button to reset the player, when I press it, it sends the string "Reset" and the unit resets without a problem.But when I add a code to close the winsock connection upon reset, it doesn't send the string to the unit. I am sure what is happening is the winsock is getting closed at the exact same time it is trying to send the string and so it fails to send, how do I make it close winsock AFTER the string has been sent?

View 1 Repliesafter reading a topic that Chris Rutland wrote about student in final year (link)[URL]...So i was able to complete this in roughly 15 Mins give or take. it also said multiples of three and five. Which i would have understood as 3 * 3, 5*5 as so on, but when I thought about it they would never match within 1 - 100 so I took I must have misunderstood so I then done it as 3 + 3 and 5 + 5 and so on. Which would then give matches for FizzBuzz. So my question is from my code below what would you do different. Could any of you write this with less lines and if so how.

So for example,95430 seconds should equal 26:30:30 (hh:mm:ss) however comes out at 02:30:30.Here is the sample code, note I have tried using TotalHours, TotalMinutes TotalSeconds however this does not give the correct result.

View 2 RepliesI 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've created an application that runs queries against a SQL server (via Data Adaptors) in VB.NET 08 and returns the results to a DataGridView. It works great and returns my data, but when I switch to a different query that returns different columns, the DataGridView keeps the old columns from the previous query and adds the new columns from the new query to the end (far right) of the DataGridView. Is there a way to counter this? I don't want those previous unused columns showing up in my results.I tried setting the DataGridView DataSource and DataMember to Nothing and that didn't fix it.
