I am having trouble comparing two dates. One is captured from input, other one is predefined. Please see the code below: I enter this date in the textfield: 04-12-2001
Dim idatum As Date If Date.TryParseExact(aankoopdatumIDclm.Text, "dd-mm-yyyy", Nothing, System.Globalization.DateTimeStyles.None, idatum) = False Then 'idatum is true at this point...
What i would like to do is to compare the AStartDate with both StartDate and EndDate which will be done in a DetailsView both insert and edit mode. This is to make sure AStartDate is within both those dates. (Same goes for AEndDate)
At first i though of extracting the StartDate and EndDate from the database and then make the comparison. But i am having problem because both StartDate and EndDate are data type "date" as follows:
Dim strProjDate As String
Using myConn3 As New SqlConnection(connString) myConn3.Open() Dim command3 As SqlCommand = myConn3.CreateCommand() command3.Connection = myConn3 command3.CommandText = "SELECT StartDate FROM ProjDetails WHERE ProjID = @ProjID" With command3.Parameters .Add(New SqlParameter("@ProjID", TB_GenerateActID.Text)) End With strProjDate = command3.ExecuteNonQuery() TB_ProjStartDate.Text = strProjDate.ToString End Using
The above code only displays "-7" in the TB_ProjStartDate textbox.
By the way, I am using Web Developer 2008, VB.net.
i have a text box named txts_date where the date format is dd/mm/yyyy....and i have a label name lblduration...now my need is i have another text box named lble_date...i want to add the value of duration ie lblduration to txts_date and display it into txte_date...
for example...
txts_date has date 22/11/2010 and lblduration has text as 10 so i want to add both the values so the result would be 02/12//2010..

I am generating multi-series graphs with the date along the X-Axis. The problem is that not all of the series in the graph have the same dates in the date range. Meaning that if I choose 1 Feb through 30 Apr that one series may have data that starts at 1 Feb but only goes through the end of March but another series may have data for the entire date range. This skews the charts I need to create. Go, given the date range taken at the begining of the query I'd like to generate a list of dates and populate the data to be graphed, padding those series with 0's for those dates that have no data.
