Datetimpicker

Hi there!
Pls help me with my code
i want to save the values from these code wriiten below,but the value did not incremented after saving..please help me

thank you!

vb.net Code:

Dim startDate = Date.Today
        Dim endDate = DateTimePicker1.Value.Date
 
        Do While startDate <= endDate
            MsgBox(startDate.ToShortDateString)
            startDate = startDate.AddMonths(1)
        Loop
 
        strSQL = "Insert into Lenders_CollectDate (TransactionID,DateCollect_1,dateCollect_2,DateCollect_3) values ('" & txtTransacID.Text & "','" & startDate.ToShortDateString & "','" & startDate.ToShortDateString & "','" & startDate.ToShortDateString & "')"
        SQLalter_Table(strSQL)
        MsgBox("Ok")

Perhaps moving your INSERT inside the loop would be more along the lines of what you are after.

As it is, it is only inserting one record using the last date calcuated.

Seems the code responsible for the update in regards to SQLalter_Table(strSQL) which you have not shown is where the problem is. Unless you show this code all that can be done is guess so best to show your code.

what are the datatypes of:

TransactionID
DateCollect_1
dateCollect_2
DateCollect_3

???

sorry for incomplete information..to make it clear

date Today is 09/08/2011
selected date from datetimepicker is 01/08/2012

for example I want to save the value of
09/09/2011-Firstmonth
10/09/2011-SecondMonth
11/09/2011-thirdMonth
12/09/2011-FourthMonth
01/09/2012-FifthMonth
until it reached the selected value from datetimpicker.

Pls.Help me..

Thank you very much!

What does SQLalter_Table(strSQL) do ???

I just want to save the incremented months to my database...

using (do while) but it gives me values that i'm selected not the incremented values...

pls help me...

SqlAlterTable- that is my function to save and update values on my database..

your call to the routine that inserts the values into the database is outside of the loop... move it into the loop and it just might work. Call me crazy, but it just might work.

Techgnome has already provided a solution to the sql insert problem. If the problem is about adding months to the target date specified in the Datetimepicker then, the following example could possibly help you.

vb.net Code:

Dim startDate = Date.Today
Dim endDate = DateTimePicker1.Value.Date
 
Do While endDate = DateTimePicker1.Value.Date
   If startDate >= endDate Then Exit Do
   startDate = startDate.AddMonths(1)
   MsgBox(startDate.ToShortDateString)
Loop

Please Help!

It sounds like you want to save all the 6 different dates on a single click. Do you have different fields like First_Month, Second_Month etc ? Or trying to insert 6 rows all at once ? :confused: The exact problem is still unknown.
.

To make it clear...

I have a 2 datetimpicker,

This is my code



DateDIff(DateInterval.Year,Datetimpicker1,Datetimpicker2)/2


how can I get the dateinterval of Semi-Annual?

try this:

vb.net Code:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
 
        Dim SemiAnnual As Date = DateTimePicker2.Value
        Dim MyDate As Date
        Dim firstDate, msg As String
        Dim secondDate As Date
 
        MyDate = SemiAnnual.AddMonths(6)
        DateTimePicker2.Value = MyDate
 
        firstDate = DateTimePicker1.Value
        secondDate = DateTimePicker2.Value
        msg = "Months from today: " & DateDiff(DateInterval.Month, Now, secondDate)
        MsgBox(msg)
 
End Sub
