View 4 RepliesI am currently storing empty dates in MySQL as 0000-00-00. I am then using a repeater with <%# Eval("check_in_date") %> to output the date to the page.
ASP.NET does not seem to recognise 0000-00-00 and converts it to 29/12/1899.
I would like it to be treated as empty therefore output an empty string to the page. Is there a way to do this?
Using c# and SQL.
Populating a gridview and want to check whether the Taskdate which is in column 5 in the gridview contains "1/1/1900". If contains I need to make it blank. I use template fields.

protected void SubmitProject_OnServerClick(object sender, EventArgs e) {
if (StartDate.Text == "" || StartDate.Text == string.Empty) {
rec.Proj_StartDate = DBNull.Value.ToString();
} else {
rec.Proj_StartDate=Request.Form[StartDate.UniqueID];
}
}

protected void SubmitProject_OnServerClick(object sender, EventArgs e) {
if (StartDate.Text == "" || StartDate.Text == string.Empty) {
rec.Proj_StartDate = string.Empty;
} else {
rec.Proj_StartDate=Request.Form[StartDate.UniqueID];

If i have three textboxes in my vb.net webform.
Textbox1.text="Sumit"
Textbox2.text="4-Dec-2010"

I need some pointers to start on this.We are building a time off application where three instances of a calendar control will be displayed ( prev - current and next month) now users can click on various dates accross all three instances and then a count of number of days should be diaplyed in the parent textbox.
To begin with this, i started with adding the dates clicked by the user in Calendar2_SelectionChanged method into a list<> so that i can get the all dates user clicked and then add it to calander's selected dates collection. But this throws an e" object reference not set" error.
Is there anyother way to get all the dates that user click onthe calendar( note the dates doesn't get highlighed so seleteddates doesnt work)does anyone has a good example for this.
i want to use a ajax calender extender in which when user clixcks on button caleder show only dates of current month not previous dates.i dont want to disable dates. i should not apper on current month calender. means it should start from 1 and end to 30 or 31

View 2 RepliesI 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.

I am using Membership and note that all the dates set in the aspnet_Membership table are minus one hour.My development platform is XP and my timezone is set to GMT + 0.00 with "automatically adjust clock for daylight saving changes" checked.Currently we are in British Summer Time (joke!) which is GMT + 1 hour = BST.If I set a DateTime field = NOW(), the DateTime field is set to BST.When using the Login control, however, the DateTime set in any field, LastActivityDate, LastLockedDate or FailedPasswordAttemptWindowStart, is BST - 1 = GMT.First question is, should I set dates to be in GMT all the time or BST when it applies?If GMT all the time (which seems to be the preferred option?), how do I remove the daylight saving time when I set a DateTime field?If BST when it applies, how do I add this to the dates set by the Login control?Your help would be much appreciated (any codes snippets preferably in VB, please).

View 12 RepliesSay I have a table called "Visits", and I want to create a query that counts the visits per day. The way I would accomplish this would be to create a query as such:
SELECT Count(VisitId) as VisitCount, Convert(varchar(32), VisitDateTime, 101) as VisitDate
FROM Visits
WHERE VisitDateTime BETWEEN '10/1/2010' AND '10/5/2010'
GROUP BY VisitDate
The problem I am trying to overcome is that if there were no visits in a given day, that day does not show in my list. For example, if there were 3 visits on the 1st, 2 on the 2nd, none on the 3rd, and 5 on the 4th, my result set would look like:
3, 10/1/2010
2, 10/2/2010
4, 10/4/2010
How can I create my query so that I get all days in the date range listed in the result set regardless of whether the VisitCount is zero?
