VS 2008 - SQL Statement Between Two Times
Mar 31, 2009
I'm wondering how I would go about retrieving all the times between Two Times. I have 4 Textboxes.
1: Hour 1
2: Minute 1
Between
3: Hour 2
4: Minute 2
E.g if I have a list of times:
15:34
16:12
18:08
09:17
10:26
21:05
21:35
21:45
21:50
22:18
23:10
My
Dim Time1 As String
Dim Time2 As String
Time1 = (txt1H.Text & ":" & txt1M.Text)
Time2 = (txt2H.Text & ":" & txt2M.Text)
[Code] .....
How Would I Go About retrieving All The Times Between Say "21:20" & "22:30".

I have now started posting to a MySQL database created by someone else. I have no ability to change the table structure.Two questions:
1) There is a date field and a time field that loosely tracks the last edit date and time. Both are fields set up as DateTime in the database. The date field always has the proper date but the date and time portion shows as
2011-11-27 00:00:00
However, the time field shows as
1899-12-30 23:16:58.
When I am updating with the following code
strSQLCmd.Parameters.AddWithValue("@EditDate", Date.Now)
strSQLCmd.Parameters.AddWithValue("@EditTime", TimeOfDay)
The date field displays
2011-11-27 23:40:26
and the time field displays
0001-01-01 23:40:26
I'm not sure how to format the date field without time and the time field with Dec 30 1899.Question 2) I will be adding some tables and will be wanting to track date and time of first entry as well as date and time of last edit. (this may have been better posted in the Database forum, if so, sorry)
For those of you who have done this before, would you mind sharing best practises? I am wondering why would you use two fields, one for date and one for time, when the field is a date/time field to begin with. I've seen this before in another database as well. I'm just trying to work out the logic here.

I have just started using vb.net and I have a checked list box with times throughout the day shown as
00:00 - 00:14
00:15 - 00:29
00:30 - 00:44
00:45 - 00:59
What I am trying to find is a way to get the current time and find which list item it fits into. What I think I need to do is to first of all get the current time and then go through the list splitting each item into 2 times and seeing if the current time fits. For example: Split the item 00:00 - 00:14 to 00:00 and 00:14 and then check if the current time is more than 00:00:00 but less than 00:14:59 and if so do certain task.how to go about taking each list item and splitting it into 2 separate times so I can check between them?

I am trying to write an app which allows the user to input two times , in a maskedtextbox, and take those two times and add them together then output the result to a third maskedtestbox, I havent seen anything else on the web with the same problem, only with fixed date or time, nothing that the user can change.
I am guessing you have to input the a maskedtextbox as a string then parse them to datetime, add the two together and the convert the date back to a string at runtime my code always bails out with a datetime conversion

I have about 1.000 text files in a folder, and I wanto to make some statistics reading the files content.In the first place I store the files path + name in a MyFiles() array, then, when I press a "Start" button I read the several files:
For x As Integer = 0 To MyFiles.Length - 1
FileReader = My.Computer.FileSystem.ReadAllText(MyFiles(x))
(data processing)
(data processing)
next
then I have copied and pasted the first 500 files in a new folder and added to the code if x > 500 the stop The strange thing is this: to elaborate the 500 files of the second folder takes about 4 seconds, to elaborate the first 500 files of the first folder (THAT ARE IDENTICAL TO THE 500 FILES OF THE SECOND FOLDER) takes 7 seconds.The same identical code takes different times to elaborate the same identical files if they are stored in different folders with different files number.

I have a button where I get data from a database that matches a search string I enter. Everything works fine the first time the button is clicked. However, if I click it again with a different search string, I get the same results as the original search string. I've tried to dispose, clear, and reset my dataset before I load the data each time, but it still finds the original query. This is the code I use to get and request the data:
Private Sub btnCfind_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCfind.Click
mdbFile = "TCICUST.DBF"
mdbCond = " WHERE COMPANY LIKE '" & cbCust.Text & "%' ORDER BY COMPANY "
GetDB()

how to get the time difference between 2 date & times Where
from_time falls >= 22:00 of the From_date & the to_time falls <= 06 of the To_Date
for example:
From_Date = 01/01/2011 20:00 ' Where Work Started
To_Date = 02/01/2011 08:00 'Where Work Ended
Time_Covered_Between_22TO06_As_Night = 22:00 to 06:00 is 08:00 hrs How to equate it?

Having problems with a datatable which consists of multiple datalogger information. Within the datetime field there are as the name suggests listed date and times entry i.e. 12/01/11 22:56:56 ect ect.
Problem is i am graphing this and when ms chart reads the duplicate entries as a series. It doesnt like it and comes up with a slightly odd interpretation. I need to get the duplicate entries out to establish a single time series.
I was proposing to clone the original datatable and run a loop to remove the duplicates. I have been trying to do this for days and have played with a whole load of examples, without success. Can anyone point me in the right direction on this.

I made my program and now I just need to add in the serial and trial part of the application. I know the application must connect to the host and go to a txtfile. How would i do the trial and serial. Also If the serial is already activated I want the application to reject that Serial and Count how many times they entered in a wrong serial.

I was convinced that If <expression> Then <statement [:statement]> Else [statements] in concrete form of If a = b Then SayHello() Else SayBye() End has sense. I read article on msdn on If-then-else, but I forgot why I was reading, so I concluded, that snippet above means this
If a = b Then HelloIsSaid : IsNotEnded Else ByeIsSaid : IsEnded But I have tested it now, and I see, that Else without statement is nothing more than decoration. It would be pretty good if it had function I described. Do you think its good request? Or do you know any circumstance where this Else has some function?
