Algorithm To Count The Time That Occured On The Same Period?

Apr 2, 2012

I have already made an algorithm for the problem but it still got a trouble.Suppose that I have the recap of schedule (contains on gridview named GV):

TimeStart TimeEnd TotalOccuredOnThisTime
----------------------------------------------
08.00 08.50 1
08.00 09.40 43
08.00 10.50 2

What I want to get from the algorithm is, to count the time that occured on the same period, e.g. on the time of 08.00, it's occured 46 event (see the yellow colored row).This is my algorithm:

Dim ColumnLength As Integer = GV.Rows.Count
Dim TimeStart(ColumnLength - 1) As Integer
Dim TimeEnd(ColumnLength - 1) As Integer[code]......

Program Freezes Over A Period Of Time (5sec)

Mar 15, 2011

Is there a way to code, so that if your program freezes over a period of time (5sec), it just stops trying to do it, and goto something else.

"On ERROR" wont work, since its not a error. "Try" doesnt work ether.

Its because I'm am programming something that can login to a router thought telnet, and sometimes the telnet ActiveX doesn't read the buffer or the line proberly, so when the .GetLine() func is called, it freezes. And i want away to goto another point if it keeps freezing for more than 5secounds. The telnet ActiveX that, I am using is Dimac w3sock.

Display A Certain Message For A Quick Period Of Time?

Apr 10, 2012

I am developing an application that prompts an user for doing certain tasks in a form. What i want is that a certain message should be popped for a certain amount of time and then close (probably say 2 seconds or so). I tried doing it with message boxes but they do not close on their own as they are designed to be modal (to wait for user command ). i do not want to display the text in a textbox of listbox. Is there a certain way i could do this.

VS 02/03 - Calculating Date Differences In Time Period

Oct 6, 2009

I know about DateDiff and TimeSpan. I am doing a project. I save a date in the registry. Now, I have to test this date against today's date and calculate the differences in minutes, hours, days, months, weeks and years.

I save the date in the registry like this:
Application.UserAppDataRegistry.SetValue("Date", [Date])

I then made a sub to calculate the differences:
Private Sub Calculate()
Try
Dim DateGen As Date
DateGen = CType([Date], Date)
Select Case TimePeriod
[Code] .....

As you can see, based on the difference between these dates ( today's date and the registry date ), a sub gets called and the program continues. Unfortunately, the minutes and hours never calls the RandomAlpha sub. How can I calculate the difference in minutes, hours etc.????
