I need a start date, a Total time passed until now, an average time per step, and a estimated time to finished. How can I do that? Also, I can close the application and when start up again I want to get the time counters as the last time, so How can I store that data is normal txt file (I say txt to take advantage of the ini app file which is a txt).
View 1 RepliesI have a webserver and I upload files to my webserver from time to time. I have an ftp account which points to public_html that is main directory.
I though why give full access so I created another ftp account (e.g. test) which points to a specific folder. Now when I try to upload a file using test it fails.
For e.g.
the following code works:
My.Computer.Network.UploadFile("d:ok.txt", "ftp://mysite.com/Test/okay.txt", "main@mysite.com", "mainpw")
- this is because this a/c has access to root folder of website
now following code gives error -
My.Computer.Network.UploadFile("d:ok.txt", "ftp://mysite.com/Test/okay.txt", "test@mysite.com", "testpw")
The remote server returned an error: (550) File unavailable (e.g., file not found, no access).
Well the ftp account test has been given access to a specific folder with the name "Test". So it should at least upload to that folder.
But if I use ftp client (like filezilla) then it works.
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?
im trying to convert a 24hour time input in a textbox into a 12hour format and place the answer inside another textbox 1345 = 01:45 this and also whats the easiest way to block out a number like "1365" (01:65) from being entered/run ?

I've been looking, but don't know the correct search criteria (english not native)I have 2 values (sometimes many more, but this is an example):
00:03:00
and
0012:21
How do I add them, of course these are time values, they are read from an collection of music files, and I would like to calculate how many hours minutes (and maybe secs) the whole collection is.

I am developing a portion of an application that deals with settings reminders and alarms for personal notes. I am trying to insert from a formatted datetimepicker( formatted to show time only ) the time a user wants to get a reminder of something he/she wants. The column in the MySql database is of type 'Time'. I was never succesfull in entering and saving the data. Either I was getting validation problems not allowing me to exit the datetimepicker after I choose the time. To resolve this issues I just made 'false' the option 'causes validation'. Now the problem is that the time is not inserted getting problems saying that :
Quote:
Specified cast is not valid.Couldn't store <01/01/1753 00:00:00> in ntime Column. Expected type is TimeSpan.
here is the code for saving
Dim xtime As DateTime = New DateTime
xtime = Me.NtimeDateTimePicker.Value
Dim result As DialogResult

This time it does not even insert a new row it just updates the last entry I have changing its time. This is strange as this happens only when I use the above two lines.
I have a Date variable called Time1In.
I'm getting a time value as a string from Excel, so I assign the date variable a value like this:
the string value coming in from excel is this:
30/12/1899 7:40:00 AM
my code gets the time value and assigns it to the date variable:
TimeIn1 = TimeValue(strTimeIn1)
the Date variables value is then this:
#7:40:00 AM#
which inserted into my database datetime field then looks like this:
0001-01-01 7:40:00
That causes errors when loading the page. I need to set a date value on the date variable. How can I properly append a date to the variable?
I have an app that encrypts a file, and I would like to have an estimate of the time remaining, but I don't know how.

View 10 RepliesI am currently running through a loop with 20 threads. These loops contain a series of 3 HTTPWebRequests (relatively CPU intensive). At the beginning, CPU usage never spiked above 10%. After about 7 hours of run time, CPU is spiking up to over 40%. I believe that this will eventually lead to the program crashing (it has before in less time, I modified some things and it seems to be running longer). What kind of intense CPU spikes are associated with threading? More importantly, how can the duration of runtime affect CPU usage by so much?
