i want to compare two data values in my database.These two dates belong to two different columns.What i want to compare is if the date of one column greater by 6 months from the date of other column then it should give error.I want to pass this query to database and check,and later on depending on the result want to insert my other functionality?
View 1 RepliesThis may perhaps be a stupid question but I just can't get it to work.
I have an if clause where I compare a textfield with the value of a datareader.
It looks a little like this if me.txtfield1.text <> reader("field1") OR me.txtfield2.text <> reader("field2") ETC... I do this for a lot of field.
But now I want to check if field2.text is string.empty and if it is I want to skip the comparison for that field.
I have two textbox in my application.
Textbox1.Text="19-Jan-2010"
Textbox2.Text="Jan 2010"
May I know how can I compare that Textbox1 and Textbox2 text is within same month and same year?
I'm trying to compare the modify date of a file vs the current system date. I've found an MSDN article describing how to get the modify time of a file:
Dim infoReader As System.IO.FileInfo
infoReader = My.Computer.FileSystem.GetFileInfo("C: estfile.txt")
MsgBox("File was last modified on " & infoReader.LastWriteTime)
This gest the Date and Time, but I want just the Date not the time.
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.
how can I create following thing with Visual basic?I would like my excel to check the date value in a cell and compare it to current date and if the value in the cell is older than 2 months compared to current date it would change the cell's colour.

I have 2 Textboxes with Date/Time in them. I want to test if one is less than the other, here is my current code
Dim StartTime1TextBox As TextBox = TryCast(FormView1.FindControl("StartTime1TextBox"), TextBox)
Dim EndTime1TextBox As TextBox = TryCast(FormView1.FindControl("EndTime1TextBox"), TextBox)
If Not [String].IsNullOrEmpty(StartTime1TextBox.Text) Then

However if I enter an Start time of 9:00 AM and an End Time of 5:00 PM this triggers the isvalid=false because 5 is less than 9. Doesn't look like it's comparing the date and time just number.
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

View 1 RepliesMy collegeue and I have been searching on the net a hell of a lot for a problem he is facing and we so far have been unable to find a resolution.He has an Access Database where one of the columns is of Date format. This date is in UK style (as defined by the Operatins System)
In his application there is a datetime picker which the user picks from he then wants to select * from the access database where the dates match but because the DateTime Picker is giving a US Format date (i.e MM/dd/yyyy) and in the database its UK (i.e: dd/MM/yyyy) its not finding a match and returning no records.

View 5 RepliesMy application is in VS2008 coded in vb.net.I have a table with three columns FromDate,Todate and Schedule.FromDate and ToDate will have date values whereas Schedule will have a any of these values(weekly,Monthly,Yearly) In my Form i have given some provision to the user to check the records.
My requirement is The currentdate that is Today's date should be compared with the values of Fromdate and ToDate.First it should be check whether Schedule value is Weekly or Monthly or Yearly.If it is weekly than it should check the record in between fromDate to ToDate with a increment of one week.That means it should first check the first value of fromDate than add 7 days to the value and then again check from fromDate and this should continue till it reaches Todate.
