View 1 RepliesIs there an event that I can handle that is fired when the computers system time is changed?
My program timestamps things, and I want to make sure the time is correct. So when the program starts, I will run a query (SELECT GETDATE()) from my SQL server, and record the difference, in seconds, between the SQL server time, and the time returned from NOW(). Then when I timestamp things, I will just adjust the time. I cannot run a query every time. But, if someone changes the clock on the computer, that would throw the timestamp off. So I need a way to know when this has happened, so I can recalculate the difference.
i want to create a system that will trigger alert based on few condition, my condition is:the alert will trigger if there is a negative value for 2 consecutive years.

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 just decided to recode my personal alarm program from scratch, new functions, ui etc and optimize it but I'm stuck on a part.
I have the option to start an alarm and set it to expire at a specific time, say in 2 days 5 hours 18 mins 10 secs. I was wondering what would be the best way (performance wise) to achieve this.
how trigger an event on specific time of day?
View 2 RepliesI guess this is really a Visual Basic question, but I am trying to implement a choice of Strings statements based upon the month.
example: I am making a monthly free drawing, and I have made a SQL db table that has the months as the primary, then the prizes. I want to be able in VB to get the current date (which I can do) and make 12 IF statements that are the Months so that the proper data is pulled from the table.
IF CurrentDateTime.Month = 1 then SelectStatement = "SELECT FirstPrize, SecondPrize, ThirdPrize FROM MonthlyDrawing WHERE Month = January" and so on
So if I know how to get the current datetime, how do i access the month part and apply it? AnnualCountDownTime.Text = DateTime.Now.ToString("D" This is what I currently use to display the time.
I have a TreeView with dynamically added nodes which I am using to actually contain textual data. I am using the tag field to contain special info for acting upon, based upon the node's tag. I have tried using treeview.SelectedNode.Tag. However, the selected node is the one most recently selected (like with a left mouse click), not the node I right-clicked. I have also tried using the contextmenustrip.SourceControl, but the source name for the control is always the container, the treeview control rather than the individual nodes. I have even tried associating my ContextMenuStrip dynamically to each individual node as it is added. The behavior is the same.A workable solution might be to cause a left-click when I do the right-click to bring up the context menu strip. I haven't been able to figure that one out yet either.
View 3 RepliesI have a main form that has a dynamically generated treeview and also a panel control. Depending on the selection made within the treeview the panel docks 1 of three diffrent usercontrols which are full sub forms(done for ease of modifing design of sub form rather than layering panels on top of panels).Upon button click withing usercontrol i wish to trigger event within main form.For example delete button wich then triggers to remove current selected node from treeview. code for 1 of three diffrent user controls
Dim ctrlQ As New QuoteUC(TrViewQuotation.SelectedNode)
PnlSubFormDock1.Controls.Add(ctrlQ)
Code for delete button for which i need to raise event.
If MsgBox("Are you sure you wish to delete this customer ?", vbYesNo, "Delete Record") = vbYes Then
Deletecustomer(n)
End If
i have to develop a software for motorola mc9090 that reads barcodes and rfids simultaneously, so i need to catch two different triggers: the one on the keyboard for barcodes and the other in the backside for rfids.the problem is that i didn't find any sample that illustrates how to set the trigger to read only barcodes, i found something on emdk 2.5 samples that shows how to set the trigger to read rfids but nothing for barcodes. So when i press any trigger the barcode reader is always enabled with rfids reader.Does exist a way to manage them with separated triggers?

I have one text box that contains a value for the "Start Time" and another text box that contains a value for the "End Time."Both of the values are expressed in a format for military time (i.e. 1200, 1300, 1430, etc.).When the "End Time" text box loses focus, I would like the "Elasped Time" (expressed in minutes) to appear in a third text box.Seems easy enough...right?Well the problem I'm having is since the first two numbers in military time are base 24 and the last two numbers are base 60, a standard calculation subtracting the "End Time" from the "Start Time" does not yield an accurate result.

But i can't seem to create this, what i did was to sort the time first from lowest to highest. Then sorted the points from highest to lowest.
Now my problem is, when i display the results. This is what i get.

View 1 RepliesI have a table which contains the start date and end date, in my db. What I currently do is simply display both the fields in a ListView control.

But the only difference is, I'm going to display a clock's image as background and the shading is based on the time.
