Get The Date Of The 5th Weekday Of Each Month?
May 29, 2009My program is to read serial port based on the timer, so every ticks, it reads the value and write it to a textbox.The timer in the form is in the interval of millisecond. Therefore I make it 1, that means every 1ms, there is an event.The event I try is as simple as writing in a text box.
[code]...
the last code is meant to measure how many seconds will I get from d = 1 to 1000, it should return 1 second time difference. But instead of 1 second, it returns around 15 seconds.

View 1 RepliesVS 2008 WeekDay / Name Function
Mar 16, 2010I have a question about the WeekDay and WeekDayName functions:
[Code]....
The parameter "FirstDayOfWeekValue" is supposed to represent "the first day of the week", but I don't understand how it's used. I mean, if the date is 16th March, then it's a Tuesday. That's true everywhere in the world and under any condition, isn't it? If that's so, what is the relevance of "FirstDayOfWeekValue", which apparently lets you change the weekday of a given date? And what is the "proper" value I should use, in order to get the correct result (ie. 16th March = Tue)?
.net - Calculate A New Date Simply By Using The Build-in Dateadd Function?
Oct 14, 2009I would like to calculate a new date simply by using the build-in dateadd function, but take into account that only weekdays should be counted (or 'business days' so to speak).I have come up with this simple algorithm, which does not bother about holidays and such. I have tested this with some simple dates, but would like some input if this can be done in better ways.This sample assumes a week with 5 business days, monday-friday, where first day of the week is monday. Dateformatting used here is d-m-yyyy, the sample calculates with a startdate of october 1, 2009.
Here is the simple form:
Dim d_StartDate As DateTime = "1-10-2009"
Dim i_NumberOfDays As Integer = 12
Dim i_CalculateNumberOfDays As Integer

View 1 Replies.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.

Then I need to show which date/time ranges overlap each of those intersecting sections. It is slightly more complicated than that so I'll do my best to explain by providing an example. I am working in VB.Net, but C# examples are acceptable as well as I work in both.
