VS 2010 Results Displayed After Checkbox + Date Range Entered?
Jun 3, 2012
I am trying to make a Windows Form in VS 2010 that is used to determine whether someone is entitled to a prize/medal/award whatever you want to call it. So basically if someone clicks on a check box to say they attended an event and they enter a date range between saying they attended the event between 01/01/2010 - 01/02/2010 and the requirement for the award is that they attended the event for more than 20 days then because the statement is true I would want a box to pop up and say person is entitled to receive a particular award. There are multiple awards available based on different conditions so to be eligible for so the result would be dependent upon which boxes and date ranges are selected.So For Award1 the logical argument is something along the lines of
IF Event1CheckBox = Checked AND
Attendance => 20
Result = Entitled to Receive Award1 Else = Not Entitled To Receive Award1

How to get if the date entered is in the range?
Ex. the month of April, the number of days is only 1 to 30. What if the user will enter the date range of 4/1/2011 to 4/31/2011 in the mask textbox? I am using Mask textbox because datetimepicker will not accept empty value and it cannot be empty either.
I'm asking this because I encountered an error when querying in MS SQL SERVER 2005. It says "The conversion of char data type to smalldatetime data type resulted to in an out-of-range smalldatetime value." I thought it was the casting or conversion problem. I've observed the SQL when transacting and I found no difference with my code.
So then, I just figured it out that my date exceeded the number of days of the April month.

I'm wanting to loop through a range of dates set by date time picker. This is my code and as the SD.Value.Date is 23/05/2010 it shows Sunday for me. However on the Loop it keeps showing Sunday and Never stops.
Dim SD As Date = StartSearchDate.Value.Date
Dim ED As Date = EndSearchDate.Value.Date
Do While SD.Date <= ED.Date
MsgBox(SD.DayOfWeek.ToString)
SD.Date.AddDays(1)
Loop

I am pulling data from a SQL server database into a dataset. The date are a DateTime type:
[Code]...
I can see the data in the field reads: 2011-09-09 15:56:29.667. I have tried to convert this by adding convert(varchar(10),DateFrom,103) which results in 09/09/2011 and then Custom Formated the DateTimePicker but still no success.I think I might be going completely off track here so can someone guide me on where I am going wrong here or the best way of doing this

I have attempted this code for an application that calculates and displays change in terms of quarters, dimes, nickels and pennies. The user inserts the amount paid and the cost of the item both expressed in cents in two textboxes. Then I have four labels displaying the results for each kind of coin. This is the process for the button I named Calculate:
Private Sub btnCalc_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalc.Click
' Variables for fields

I have a need to verify SSN's that are entered based on a reserved range (these are used for advertising and will never become valid). The input is from a masked text box formatted as 000-00-0000. I may be wrong, but I figured the most logical method would be to remove the hyphens and convert the string to an integer, then compare the starting point and end point of the range.
'Valid SSNs
'Currently, a valid SSN cannot have an area number between 734 and 749, or above 772, the highest area number which the Social Security Administration has allocated. This should not be confused with Tax Identification Numbers which include additional area numbers.

I need to compare the date that is entered with today's date minus some number of work days.
I used dateinterval.day, but that is the actual day, not the work day. i don't see a "simple" way to get work days.
For example, my number is 3, so i want 3 work days (M-F) not 3 days.

I'm working in visual studio 2005 and developing a windows form that has a datagridview on it.
One of the cells is a Calendar Column type (custom made). I pulled the code for it off the internet - it basically allows the user to select the date from a small calendar.
When the date is changed, it gets the correct value and it also saves into the database with the correct value.
The problem is that it doesn't load onto the grid with the correct value. In fact, no matter what date I enter in, it always displays it as 1 day earlier. e.g. If I saved it to the database as 4/19/2012, it displays it as 4/18/2012.
I verified that there's no other column in the query that retrieves the data for the grid that contains the value it's displaying.

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)

I have several records in a database that have Start and End Dates
09/15/2011 - 09/30/2011
10/15/2011 - 10/22/2011
11/01/2011 - 11/15/2011
When user stores a record, I need to make sure dates don't overlap.My simple code checks date ranges within a specific record (e.g. user enters 9/16/2011 or 10/21/2011, I throw an exception.)But, on the slim chance a user gets creative (e.g. 10/14/2011 - 10/23/2011 or even 10/14/2011 to 11/16/2011), now they have circumvented my check.BTW, the user could enter 10/14/2011 to 10/23/2011 if they were editing the record that contained values 10/15/2011 - 10/22/2011.So, I'm trying to solve this riddle with a linq query. However, what I have isn't working exactly right.
UPDATE Nevermind about code not working. While trying to provide an example to expand on Miika's repsonse, I found my answer. So, giving credit to Miika for pointing me in the right direction and posting my working code below:
Here's my code:
Private Sub CheckForOverlap(myMonth As Messages.MyMonth)
Dim am As New MyMonth()
Dim amCollection As Messages.MyMonthCollection

I have created a small program that performs various calculations with data entered by the user. I need to be able to save the entered values and the results on the system running the program and be able to open it at anytime in the future and have the values and results displayed in the correct text boxes. I am currently reading up on some tutorials but I was just curious as to how I can send all my data in Visual Basic to my database in Microsoft Access?

I am trying to get a list of dates from a provided StartDate and EndDate in my database, and use these dates to link to dates in a database (to display another variable on the y-axis of the chart) and to populate the x-axis of a chart (with the list of dates). Is it possible to get a list of dates in VB and pass them into a chart this way?

I have a datagrid, with an unbound checkbox column. How can I get a range select use shift and ctrl keys that will check the checkbox?The moment you check a box, it selects only that row, so the rows selected are down to just the row you clicked on. I've been playing with several events and settings and I can't seem to get it. Can anyone point me in the right direction?When your problem is solved, add (RESOLVED) to the end of your topic. This will save the guru's time and be able to solve more problems. Remove the question mark icon as well.

how data is stored in a DB vs how it is displayed in a DataGridView, but i cant come up with a solution to my problem ...I have a DGV being filled by a Datatable. I have set the DGV Date column to format as "yyyy-MM-dd" and it shows that accordingly.
DataGridView1.Columns(9).DefaultCellStyle.Format = "yyyy-MM-dd"
I also have a sub that USED to take the DataTable that filled the DGV and used it to generate a CSV file. But since i had modified how the date was displayed in the DGV i decided to change the CSV Export to use the DGV instead of the DataTable.
Dim writer As System.IO.StreamWriter
writer = File.CreateText(PathToSaveFile)
For intRows As Integer = 0 To DGV.Rows.Count - 1
[code]....
My issue is that even though i changed the VIEW in the DGV to show me the date how i want it, the CSV does not take the displayed date when it writes the lines, it seems to still take the DB date, and then displays it as "dd/MM/yyyy". how am i supposed to tell the CSV Sub to change how the date is displayed in this file ?
