I am writing a personal accountant software using VB2010. What I'm looking for now is to get the week date range of a specific date (Monday to Sunday). For example, if the given date is 16/03/2012, I want to get back:12/03/2012 -> 18/03/2012
View 5 RepliesWhat I am trying to create is a log in system, and in one of my forms I want to limit the date entered into a form. For example a user cannot enter a date more than seven days from todays date Which is what i achieved but what i am stuck on is preventing a user entering a date in the future

I need to generate a report that shows the 52 weeks of a year (or 53 weeks as some years have) and their start and end dates. There is an ISO spec to do this but seems awfully complicated! Im hoping someone knows of a way to do it in C# or Visual Basic (its actually for Visual Basic 6 but I will try port it across)
View 7 RepliesI am in a VB 2010 class right now, and I'm suppose to write a program that requests the user's date of birth and then display the day of the week (such as Sunday, Monday, ect...) on which day they will have or had their 21st. Birthday.
I already have the GUI made up with a MaskedTextBox set to simple date and it is named = mtbDayOfBirth
I also have the button already to calculate this, and a read only text box named = txtBox2.
My code so far is:
Private Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim d As Date = CDate(mtbDateOfBirth.Text)
txtBox2.Text =
End Sub
End Class
The only thing in my book only talks about how to pull the number of days from your bday or pull the full birthday as like the 04/06/1992 would return Monday, April 06, 1992.
I am creating a program that takes into account pay from a job. I will try to describe the problem I am having using some psuedo code - so dont take syntax too seriously.
I created a structure that has some of the following values:
Name as String
Amount as Double
FrequencyType as MyEnumerator
MyEnumerator looks like this:
EveryTwoWeeks = 1
TwiceAMonth = 2
Weekly = 3
Now my problem is how do I add the date ranges into my structure?If your pay is weekly or twice a week, then I just need a single date because all other paydays should increment in 1 or 2 week blocks. But if the pay is twice a month I need two dates. It seems like there has got to be a better way then just having two dates in my structure and knowing that you just need the 2nd date if the FrequencyType is = 2 (TwiceAMonth).I was thinking that instead of a Structure I should use a class and then I could create a function that returns the date or dates depending on the enumeration type that you pass into it.What would be the "correct" way of doing this? I think I need a type of enumerator that allows for more then just integer type values.

I am developing a billing application to help out the billing lady who has been doing our billing by hand. I am essentially done�. Except for one class of customer I can�t wrap my head around. Nuts and Bolts:
1.Data comes from a table that shows Storage id, customer id, Billing Start date, Billing end date.
2.I am kicking the data back out to a table and I�ll build her a nice little crystal she can run.
Problem:We rent storage space. If multiple customers use the same storage then they will split the cost of the daily fee. If there is 3 customers they each pay a third etc. This seems simple but If Customer 1 starts on 1/1/12 and ends 1/10/12 she pays 10 days. If Customer 2 comes in 1/3/12-1/9/12 they will split 7 days. If Customer 3 comes in only on 1/9/12 then they will all pay a third on that day. Now imagine this across 600+ storage units and 1000+ customers and each customer using multiple storage at any given time.
My biggest issue is I don�t know how to express how we do that calculation by hand programmatically. By hand process and how I figure I am eating the elephant: Find every Customer that has used the Space in the billing period -Determine the unique storage numbers that were used during the billing cycle kick the results to a storage table on an access database. I am using a table because I figured it would be less of burden for the application then a list or array.
Determine where there is overlap - Use �FOR� to cycle through the orginal data table using the unigue. Here is where I am stuck. How do I compare the dates in a way to determine which customer is using it when compared to the others. Obviously i can determine the difference in dates between the start and end. It is getting the applicaiton to recognize the dates are with in the other dates. here is kind of what I was thinking obviosly this doesn't work I am just using the format so don't crush me too bad because I code like a caveman.
Dim CustomerDifference as time span
Dim UniqueStorage as Integer
Dim Customer as string

Would it be possible to search a table, confining to a specific date range based on a date-time column, and get a count of the 10 most used words in a particular var-char column excluding a list of words?All in SQL?Currently I am pulling out the records that match and sorting through the contents outside of SQL, I would think where I can do it directly on the server it would be more efficient.(SQL 2008)
View 4 RepliesThis is my first program and have absolutely no training in programming Visual Basic Studio 2008 so forgive me if I have missed something obvious.Form3 contains a StartDate(Date Time Picker1)and EndDate(Date Time Picker2) with a button1 which launches a Form4 containing a report( Microsoft Report Veiwer)
I have been able to generate a report but it gives me everything in the database instead of date range selected.I have tried generating queries,stored procedures and writing additional code but nothing seems to work.( Though I may of but them in the wrong place)

I need to calculate the location of intersections between multiple date ranges, and the number of overlapping intersections. 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.
We have several high risk tasks that involve the same system. Below I have three example jobs named HR1/2/3/4 with start and end date/times.
HR1 {1/6/2010 10:00 - 1/6/2010 15:00}
HR2 {1/6/2010 11:00 - 1/6/2010 18:00}
HR3 {1/6/2010 12:00 - 1/6/2010 14:00}

Given a week number, I need to get the date of the Monday of that week.For example, I have several strings that are stored in a file, such as

The Monday on Week 28 of the year is 12 July 2010
