if the subtracted date is a saturday or sunday then subtract more days, before adding to arraylist..when i do this, the date stays the same and doesnt subtract, i get a conversion string to double error.[code]
I need to add a gridview to my page where the sqldatasource is based on a query that returns records that fall between Sunday and Saturday of the current week. (Each record has one date field) The records are for payroll purposes and the payroll week runs from Sunday to Saturday. I need to find all records that fall in the current pay week.
I have a two buttons: Previous Week & Next Week When i run the app the LabelDate needs to shows up "May 31, 2010 - June 6, 2010" When i click a previous week button i want to set LabelDate's text to "May 24, 2010 - May 30, 2010" If i click Next Week button i want it shows up "June 7, 2010 - June 13, 2010" Means it should always display previous/next week starting from Monday and ending with Sunday.
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)
How can i knoe every saturday of every month...i have the attendance date but when i calculate for report then i need to subtract the saturdays..so how can i knoe that there was how many saturdays in that month and how many saturdays ll be in next month and so on..
I think I have a function that'll throw up a messagebox if the current day is the Saturday before the Daylight Saving Time change for the US. The days it changes is the 2nd Sunday in March and the 1st Sunday in November, the time doesn't matter in this app, just the date.
Private Function CheckDST() As Boolean With DateTime.Today Select Case .Month 'Month is one based
The problem that i have right now is that i don't really know how to compare two dates.What i am actually trying to do is to compare the Date Today with vbSunday, vbMonday etc using if. But something goes wrong. As for an example:
I need to count the sick leaves in a month, for that i have to ignor Sat-sun on a datetime picker. how to i set the DateTime picker to ignor Sat and Sun? Assume there are two date time pickers dt1 and dt2 thus there difference will return teh number of days without counting sat-sun.
I'm doing this program in Visual Basic and its supposed to calculate the GPA by entering the completed courses in a listbox. Its does calculate the GPA as its supposed to by adding the values using a "Add to list" button, but i have to also update the value of the GPA if a remove an item from the listbox using a "Remove from List" button. Is there a way a remove the line and also make the subtraction work.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAddtoList.Click 'This is the Add button course = txtCourseName.Text
As part of a school assignment I have to design a program that allows people to add items to there backpacks but only upto a certain limit depending on age height etc. I completed the code to work out each packs maximum weight and thought I had almost finished but... Now I am trying to use a list box to add up the total weight of items added to each pack (below) but rather than add up I am just assigning the value 5 to the pack1weight.
Code: Dim pack1weight As Integer Dim tentW As Single Dim maxweight1 As Single
Im new to vb.net but learnt quiet abit, im using a book and getting to the stage where it gets confusing, anybody know of any videos or a better way to learn? first of all I have connected to a database but i want to beable to get the servername, username and password from a registry file instead of putting it directly into the code,
Also in the database I can add and update records etc... how would I make it take the current value in the table and add / subtract to it then update? eg. in the table i have 60, i want to add 10 to the value so 60 + 10 = 70 update record with 70. etc.
I wonder how I can subtract cells in VBA? I want to use an For-loop that subtract column "B" with column "C". I want it to take all the values in kolumn "B" minus ( - ) all values in column "C" in the whole range.

I'm Currently working with a payroll system with daily time record.. I'm having troubles with their time records, what i did is this, i created 6 textboxes on the form the 1st textbox is for the AM IN 2nd is for the Lunch OUT the 3rd Is for the total hours worked for the half day, and the same for the 4th to 6th textboxes. I actually get the difference of 2nd and 1st textboxes and show the result at 3rd textbox and same for the 4th-6th textboxes using this code that I also get in this site
Dim TimeA As Date Dim TimeB As Date Dim hh As Integer
but i really didn't understand it so right now I don't know how to add the value of textbox3 and textbox6 so I could get the total hours worked of the employee..
I'm writing a program that checks something once a day. When the property has been checked, I store the "Now" value as LastCheckedDate. Since this is a dateandtime, in includes both the value of the date and the value of the time. The next time the program is run, I want to determine if the current value of Now has a different date than the LastCheckedDate. The problem is that functions like Datedif subtract the two values using the times, so if the first check was at 16:30 on 11/2/2011 and the second check was at 9:05 on 11/3/2011, the result is about 16 hours, which is 0 days.
I have some problem with my project.1) I want to convert String (ex : "14/03/1987",...) to system datetime2) I want this function : Subtract(date1,date2) ==> result: if subtract(date1, date2) > "1 month" then ......do something else if .........do something
My question title says all. Suppose the given date is 7th july 2011. So what I want to get in result is 6th July 2011. And leap years aren't to be counted. The day number always should be one less than today. I did this:Dim year As Date = "1/15/2009"''adds 1 years to current dateMessageBox.Show(year.AddYears(1))
I'm completely new to programming and wondered if you could help me. I've designed a simple calculator that can add numbers together but am now trying to create a subtraction button. This seems more complicated, I've searched various forums but am a little confused and wondered if any of you can help or point me in the right direction. Here is the coding I've done for the Add button (cmdPlus):
Private Sub cmdPlus_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdPlus.Click
i have a problem regarding datagrid.remove and textbox. This is a Function to Add and Subtract Values on a specific Column. If I cellclick on the main datagrid on a specfic row which has record where the record goes to the other datagrid with no record yet to be filled with record, the textbox will count/ add all the values from the UNITS COLUMN and in an instance on one row removed in the other datagrid, the total value of units in the textbox does not subtract or less. here's the code.
Public Function total_units_remove() As Double Dim totalunits As Double = 0 Dim i As Integer = 0
