Number Sorting, Lowest To Highest, With Text In Front?
Nov 14, 2009I'd like to know how to sort an array that has entries with numbers after text.
I have a list of four entries:
Book 1
Book 2
Book 11
Book 12
Using Array.Sort(aBooks) returns
Book 1
Book 11
Book 12
Book 2
Is there a way to have it sort lowest to highest like 1 2 11 12 instead of 1 11 12 2?
Get A Numberupdown Text To Show The Value "+" So If The Value Is A Positive Number Then It Adds The Plus Sign In Front Of The Digits?
Sep 29, 2009is there any way to get a numberupdown text to show the value "+" so if the value is a positive number then it adds the plus sign in front of the digits.
example:
2.00 would become +2.00
3.25 would be +3.25
as when its negative its
-2.00
-3.25
It already adds the negative value when its negative of course.

Use DateDiff Calculation Around Textboxes?
Jan 15, 2011I`m migrating access database to vb.net. I have employee database with a few DateTimePickers, textboxes, and comboboxes
In access I have formulas in textbox's control source like this, and it works:
txtDayCalculation=DateDiff("d",txtDateofHire, txtManualDate)txtYear=Int(txtDayCalculation/365)txtMonth=Int((txtDayCalculation-(txtYear*365))/30) txtDay=((txtDayCalculation-txtYear*365))-(txtMonth*30).
So, I have trying to do also in vb.net, but NOT successfull. Maybe my aproach to write a code is wrong. Anyway, I have write like this:
me.txtDayCalculation.text = DateDiff("d",txtDateOfHireDateTimePicker, txtManualDateDateTimePicker)me.txtDayCalculation.text = DateDiff("d",txtDateOfHireDateTimePicker, txtManualDateDateTimePicker)

.NET Equivelant For DateDiff, DateAdd And Weekday Functions?
May 16, 2010I know I can import Microsoft.Visualbasic and just use the ones I used in vb6. But I don't want to ;)In vb6 DateDiff("d", dte1, dte2) would just give me the number of days between the 2 dates and it didn't matter which order I put the 2 dates, it would still return x days.In .Net i have Date.Compare(dte1, dte2) but I have to know which date is newer other wise I get a negative result because I subtracted a bigger from the smallerIs there no .NET way to just get the difference without having to subtract then multiply by -1 if its less than 0?ALSO,In vb6 I could use Weekday function to get what day of the week a date is and use it in the DateAdd function to find the first day of the week's date. Like so: dim firstday as date = DateAdd("d", (Weekday(today, vbWednesday) - 1) * -1, today) would like a .Net way to find the date of the first day of the week, giving that our week might not start on sunday or even monday. I need to pass a date and the weekstart day (wednesday) and have it return the date for the wednesday. Like this:dim firstday as date = GetFirstDay(Today, Firstday.Wednesday)so if the date i passed was "9/3/10" which is a friday, the function would return "9/1/10" which is the date my week started on.

View 17 RepliesDateDiff Function Gives Odd Results For Negative Days?
Jun 9, 2009DateDiff for the interval Day gives expected results for days past until present, but if the first date is further in time than the second date, it gives the difference +1. Is there something I'm doing wrong? For example, if I put in today for both, the difference is 0. If I put in yesterday and today, I get 1. This is all expected, but if I put in tomorrow and today, I get 0, and two days from now and today give -1. Why is the function giving altered results if the date is negative?
Here is the specific code.
Private Sub DateTimePicker1_ValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles DateTimePicker1.ValueChanged
TextBox1.Text = DateDiff(DateInterval.Day, DateTimePicker1.Value, Date.Now)
