Function To Calculate Dates Based On Recurrence Pattern?
Aug 6, 2010
Before I build my own and after looking for quite a while (to no avai) does any one know of a function that will return the dates of a recurrence.
For instance:
- The recurrence might be the first Monday of each month.
- The second week of each month.
So what I want is to pass the recurrence information to the function and it will return in an array all the dates that are applicable.I've looked at some other topics here but none are as comprehensive as what I need.

I've been searching on Google for a recurrence pattern class for awhile now. I need a class I can use to schedule daily, weekly, monthly, and yearly recurrences of messages. I've found references to appropriate classes but no available downloads.

Say the user specifies these two dates....
Start Date: 2010-12-05
End Date: 2011-01-15
If I select December 2010 I should get the folllowing
startdate = 2010-12-05
enddate = 2010-12-31
Select January 2011 then
startdate = 2011-01-01
enddate = 2011-01-15
Should I subtract dates? How can I get the start and enddate for the current month/year based on the overall start and end date.I'm coding in vb.net.

i'm making a program to calculate loan using dates, the customer borrows an item on a particular day and returns it on a given day else he would have to pay a certain amount of fine per day, which starts from the date of return if the user returns the item 1 day after the Date of Return, he pays a fine of 50pence if the user returns the item 3 days after the Date of Return, he pays a fine of 25pence per day if the user returns the item 10 days after the Date of Return, he pays a fine of 10pence per day and if the user returns the item 30 days after the Date of Return, he pays a fine of 5pence per day i did something like this, but it's not producing the required answer
Dim returned As Date
Dim due As Double
Dim fine As Double

I am attempting to calculate the number of months between 2 dates in vb 2008. Effectively subtracting a date in the past from the current date and then manipulating it to the number of months between the two.
I have done this in VB 6 previously, but can't seem to do it in vb2008.

I've implemented the Event Based Async Pattern for the first time in a relatively complex class. I'm having some doubts about if I've done it as it should be done, and if there are no better approaches. One of the things that make me frown the most is how I'm currently handling all the cross thread events. This class contains a decent amount of events, about 20. What I've done is created a dictionary in which I have a list of callbacks, one for each event. The keys are a value of an enum containing all keys I created. In the underneath line, eventDelegates is the dictionary, and delegates is the enum.

In VB2005 I am trying to calculate the number of business days between two dates. I must also account for U.S. holidays (New Year's Day, Martin Luther King Day, Memorial Day, Independence Day, Labor Day, Veterans Day, Thanksgiving Day/Friday after, Christmas Day). If a holiday falls on a Saturday, then the prior day (Friday) is assumed to be a holiday. Likewise, if the holiday falls on a Sunday then the following day (Monday) is assumed to be a holiday.

How do I calculate the difference between two dates to display as a number in days?I have 2 text boxes (txtHStart_Date & txtHEnd_Date) I have used an Ajax Calendar Extender to enter the dates in each of these text boxes.I would like to get the difference between these two dates to show in a seperate text box (txtNoOfDays)
I've seen the timespan function but can seem to get this to work. I'm not to sure how to declare the text boxes as the dates I would the calculation to be made from
Code:
Dim D1 As Date
Dim D2 As Date
Dim ts As New TimeSpan
D1 = txtHStart_Date.Text
D2 = txtHEnd_Date.Text
ts = D2 - D1
But I know this isn't right. I also don't know how to get it to display in the 3rd TextBox.

Assume you have controls A, B, C, D and E all with a Visibility property. You also have states 1,2,3,4,5 and 6 in which various combinations of your controls would be displayed. Currently this is being handled by switch statements for each state: i.e.
Select Case PageState
case "1"
a.visible = false
b.visible = true
[code]....
As you can imagine, this becomes a pain as every state needs a show/hide statement for each control. How can I refactor this so that adding controls and/or states becomes trivial?My first instinct is to extend the control and add a collection of states that it should display for but this sounds like overkill.
Edit:I was deliberately vague in my question in case this has other implications. In my current instance the "controls" in question are ASP Panels. Does that change anything?

Question:Given a SQL string like
CREATE VIEW TestView AS
SELECT value1, value2
FROM TABLE_0[code]...........
for each strObjectName in tables, to check whether or not the view depends on this object.But this fails on table_12 (and results in cyclic dependencies) for example, because tables contains "table_1". Aaargh.I need a regex that can check if the view definition contains a function name, table-valued function or another view...
(
For checking with
System.Text.RegularExpressions.Regex.IsMatch([code].....
But it fails, plus it doesn't account for object names embraced in brackets, like
"[TABLE_NAME]"
