Write A Program Which Compares The Difference Between Any Date In The Past And The System Date?
Mar 6, 2009
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.
I need to write a code that reads off a value from a another system's screen and compares with fixed value in .net 2005. The code should read all 24 lines of data from the screen and match to see if it is equal to the fixed value. What I have so far is:
Code:
Dim ObjScreen(6) As Object Private ObjOIA_Area(6) As Object Private OIA_Area As Object
[code].....
However the code is not working. and get an error. How can you select all or read line by line to get your desired result....
I'm trying to make this 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 the layout I've created so far, the two date boxes currently show the system date so even if I change the system date, both those boxes will adjust to show it as well. I want to try and make the system date a box without a drop down arrow and so you cannot edit the box at all. The box below is fine how it is as the user can enter any date they desire. And the text box at the bottom needs to show the difference between the system date and the inputted date.
I tried to accomplish this via a MailMessage.Headers.Set call, in VB.net. See below:
Dim objMail As MailMessage Dim objSMTPClient As SmtpClient objMail = New MailMessage() objSMTPClient = New SmtpClient()
[Code]...
To be clear: I am not doing this with malicious intent. I am working on an e-mail integration component that utilizes both UIDs and a "Last processed" date to locate the first new e-mail to integrate. I want to test cases where multiple e-mails have the exact same date/time - as the e-mail integration module should handle those situations flawlessly. If I could simply fake the date this way, I could send as many e-mails as I wanted that matches a certain date/time, rather than trying to send them with an automated script - hoping they will all be received within the same second.
i want to set the system date of my a client pc based on the system date where the sql server reside.In short i want to sysncronize the date between the client and server.I have a working code in vb6 but i dont know how to do it in vb 2008.
dim RstDate As ADODB.Recordset Set RstDate = New ADODB.Recordset RstDate.Open "SELECT GETDATE() as ServerDate ", CnAP
I have a form where a user can choose an election date. One of the most frequent errors users make is entering the incorrect due dates of reports. Therefore, I am attempting to generate the report due dates in the application using the report guidelines. For instance, reports are due 32 and 15 days prior to the election and 30 and 60 days after an election.
I know the following won't work but you get the jest of what I am attempting to do. I am assuming I will need to break down the month, day and year somehow before I subtract or add the days to the date to get the actual report date.
I'm trying to compare the modify date of a file vs the current system date. I've found an MSDN article describing how to get the modify time of a file:
Dim infoReader As System.IO.FileInfo infoReader = My.Computer.FileSystem.GetFileInfo("C: estfile.txt") MsgBox("File was last modified on " & infoReader.LastWriteTime)
This gest the Date and Time, but I want just the Date not the time.
I am teaching myself VB while creating a basic application I can use at work. Is there something in VB that will calculate a past and future date from a specific date. For instance, an Election Date falls on November 2, 2011. Once this election date is entered I want the program to calculate the reporting dates. The first report due is due exactly 32 days prior to the election. The 30 day post is due 30 days after the election.
I am using VB.net as well as Jquery Datepicker for getting dates.
In my VB.net code <tr><td> DateOfReceiving: </td><td colspan="3"> <asp:TextBox ID="DateOfReceivingTextBox" runat="server" CssClass="pastdatepicker" Text="DateOfReceiving" /> </td></tr>
I want to allow enter user only todays date or past date with format dd/mm/yyyy. I want vb.net custom validation for that. How to write vb.net regular expression.
If i double click on the dataset. i am not sure which statement to write to restrict the user so that he/she cannot enter the date in the past. i have droped the data set on the form and my data entry is through datagrid view.
i have date fields i want to validate if the date is greater than system date it should prompt user and force user to enter a correct date. but when the user wants to cancel or close that particular form without correcting the date he should be able to cancel the form. in my case it does not happen you will have enter the correct date before you can even cancel when i use Lostfocu,Leave,Changevalue
what can i do sample code below
Private Sub dtMarried_LostFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles dtMarried.LostFocus If fn_checkdate(Me.dtMarried.Value) = True Then

I am working on a project inwhich I want same date format in all project forms. I want to use a form for setting/resetting date format for whole project. whenever I will change date format in this settings form, there should be this new date format available in all forms. how can I implement this?
How do I calculate relative time?How do I calculate someone's age in C#? Anyone know how of a function in VB.NET or C# that will take two dates, calculate the difference and output that difference in an english string? For example if I pass the dates '3/10/2009' and '3/25/2009', the function would return the string "15 Days" or if I pass the dates '3/10/2005' and '3/15/2007', the function would return "2 Years, 5 days"
I'd like do make a program which returns you how old you are, in years, months, weeks and days. But I didn't get it to compare different times. Input is a string which looks like 01.01.2011 (dd.mm.yyyy).
My code so far is this: Try dim date1 as string = '01.01.2011' ' Today Dim date2 As Date date2 = Date.Now ' number of seconds since date1 [Code] .....
I am taken DateTimePicker2, DateTimePicker3 n textbox6.Now i wanted to display the result of subtraction of these two dates(DateTimePicker2-DateTime Picker3) in textbox6 automatically. I don't want to enter the result manually. Plz hlp me I need it badly. I hav already tried in lost focus event also its nt workin.
I have a date value (e.g. 2011-04-11 07:45:00.000) which I am pulling from my database (via Entity Framework). I need to pull out only the hour from the original date value (e.g. 07:45:00), get the current time, and then subtract the current time from the database time value. In pseudo-code, I'm looking to do something like this:
Dim my_date as DateTime = from_db ' This is the value pulled from the database.Dim this_date as DateTime = Date.Now ' This is pulled via a VB.NET function.Dim my_hour = my_date_but_only_hours ' Somehow, I need to strip the date off the my_date Dim this_hour = this_date_but_only_hours ' Same as line above.Dim hour_difference = my_hour - this_hour Response.Write("There are " & hour_difference & " hours left before the time runs out.")
Ok so i have a date time picker that holds a date that was entered by a user. My program works fine when ran on a computer using English(US) regional settings, but when i take it to a computer running any other regional settings, I.E. English(UK), which is the 2nd most common regional settings that will find its way to this program, I recieve an error because the Date format is backwards. What i'm curious about is how can i grab the system Regional Date format in order to rearrange my Date to fix its context?
I know that since the date is stored as a string i'm going to do something along the lines of this to break it apart:
I have two date time pickers , namely "Date_of_ReturnDateTimePicker" and "Date_of_IssueDateTimePicker". Now, what i want to do is, that when i press the "total" button, the value of issue date should be deducted from the return date value, and the difference in days should be put in a textbox.
I need to return the exact difference between two dates in the form of a string. If the dates are 01-FEB-2012 and 01-FEB-2014, the function should return "2 years" If the dates are 01-FEB-2012 and 01-MAR-2014, the function should return "25 months". If the difference is not in exact years or months, it should return the difference in days. I do not want to use DateDiff from the Visual Basic namespace so the code is portable to C#.
