Forms :: New Date Doesn't Get Set Until User Has Already Selected A Date
Mar 10, 2009
I have a form that collects user parameters to print a report. There are two DateTimePickers to let the user select a date range for the report. The selection of a date range is optional so I set the From picker to a date before any data could be present. If the user wants to select a date range, the from field is set to a very old date so it takes a long time to get to any current dates. Whe I'd like to do is when the user drops down the picker, reset the date to today and let the user scroll from there.I tried the dropdown even in the picker, but the new date doesn't get set until the user has already selected a date. Any suggestions on how to get this type of UI behavior? Also any better suggestions to streamline the process?The main objective it to collect from and to dates from the user is they want to select them and collect wide ranging dates if the user doesn't enter any.

I am traying to use the DateTimePicker to extract days diff from a date selected on DateTimePicker1 to a date selected on DateTimePicker2. I have no problem substracting the daydiff in numbers of days. The problem I have is that I need the DateTimePicker to tell me how many of those days are weekends (friday, saturday) and how many are weekdays.

Lets say i had a label with 9/6/2010 11:59:99 that was selected from the month calendar control, is there anyway to determine how many days are from the present days date to the selected end date?
so 9/4 to 9/6 = 2 days
The "2" days is the value im seeking

I have a Date type, its part of a structure holding other times.
Structure WorldTimesType
Dim Date1 as Date
Dim Date2 as Date
[code]....
'Then in my sub, which is on a timer.tick event
WorldTimes.Date3.AddMinutes(5)
The problem is, it, simply doesnt work. No error, no warning, nothing. As far as the sub is concerned it works, but the Time remains unchanged, I've tried using the DateTime type, tried adding time span instead of specifil intervals, nothing works.

I am trying to pull the data by date in vb.net. It is not throwing the error nor giving any result. Whereas It shows the results in table adapter configuration wizard when I try through query builder. I am using date time picker in the form. But I have formatted the date in the database as date.

how I can ensure that conversion of a date to a string and a string to a date will give me the same date format.
For example:
Code:
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Dim d As Date = Date.Now
[code].....
I'm actually only interested in the date part as the label text shows so f is more than I want.But also, the day and month are reversed.

I am creating a booking system, I have got it all working so that a user can select a date and a time and book, there are no restrictions so 100 people could book the same date and time.
My lecturer suggested to me that to make it so that just one person can book one time on one day the user will select a date and then the page will re-load with the times selector only showing the times which are available on this date.
I have done some tutorial work similar to this, however a little more basic showing the available slots using an except operation for example allavailableslots except bookedslots, but there was no restriction on dates, so it would just show all the times which havent been booked yet full stop. I think I will use an if statement but I am not too sure, dont really know where to start...
my tables and fields are as follows
App
Bookingid
Petid

I have a date time as a string, eg. "2010-08-02", I'm trying to convert it to UTC with the following code snippet..DateTime.ParseExact("2010-08-02Z", "yyyy-MM-ddZ", CultureInfo.InvariantCulture)When I print to the console, I get the following: 8/1/2010 5:00:00 PM.Is there a reason why the date shows up as the date before the date I'm trying to parse? I could just add a day to this to advance to the original day.

writing user info such as user, computer name, date, and time to an acces database using a button click event. Then use a query to check if the user has accepted the aggreement. If the user has accepted the aggreement then call a vb.exe that display the aggrement. I have a login script that runs the vb.exe and uses a button click that records the user info to a csv file, but if the user has already agreed to the policies I do not want it run again.

I have to display the available times in a dropdownlist called "DDL_avalTime" based on the date selected in a ASP calendar.
How the program works is that when a User clicks a date form the caldendar, it checks the SQL database. In this case the table that I'm retrieving it from is "trainerbookings" from the column "trainingDateTime". The data type for this column is datetime.[code]...

I'm fairly new to ASP.NET & VB.I've been asked to take an existing textbox that is automatically filled with the current date and allow the user to either add a "+" or "-" and a number or a spcific number and convert that into a date.I underdstand the basic concept on how to do this, but I'm running into some problems using the proper commands in order for this to work.The Textbox is called txtDate.What I've tried to do is this:
If txtDate = '+' Or '-' Then
DateAdd("d", txtDate, today)
End If
Here is what the whole thing looks like:

Sub
DateEnter_Click(ByVal

I am attempting to import data in a batch from an Excel Worksheet to a Sql Server database. Everything works except for the one date field in the spreadsheet. The date returned is off by four years from the value in the spreadsheet. Example: The Excel sheet has a date 10/24/2010 14:18, but when I look at the column in my query, the date is 10/23/2006 2:18. This pattern, 4 years and 1 day earlier, is repeated for every row in the worksheet.
The Excel column comes to me as a custom type, formatted m/d/yyyy h:mm. I receive this from an outside vendor and having them change the column is not going to be my simplest solution.
For what it's worth, the relevent part of the query is:
Select [Date Created] From MyWorksheet

I have two tables: a schedule table that contains information about how an employee is scheduled and a numbers table in which each number corresponds to a date.
[Code]...
I can do this on the SQL side or the code side. I have Linq at my disposal if I need it. The table doesn't need to be compiled by SQL. This will happen dynamically on a website and should be as efficient as possible.I don't want to have to iterate through each and look for breaks in contiguous days if I don't have to.

I'm trying to write a program which compares the difference between any date in the past and the system date, showing how many days have elapsed since that date.This is what I've got so far:
Code:
Public Class Form1
Private Sub TextBox2_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs)
End Sub
[code]....
That's what it looks like so far. I was wondering how you can automate the top label so it automatically comes up with the date when the program is run.Plus, I need to know how to display the dates difference (how many days have elapsed between the system date and the user's chosen date) in the bottom label.
