I'm trying to format a datetime field to just show the date. The datetime is bound to an asp:label and for the Text attribute I have tried the following....
Text= String.Format("{0:D}", '<%# Bind("CReviewDate") %>')
and
Text= String.Format("{0:D}", <%# Bind("CReviewDate") %>)

In all cases I get a green wavy line under the equation and the tip help says "Validation (ASP.Net): If this attribute value is enclosed in quotation marks, the quotation marks must match. String.Format("{0:D}", DateTime.Now) is the syntax that I have been told should work.

View 4 RepliesI'm trying to match a certain DateTime value with the current system DateTime. I have a timer and a label on a form. Timer interval is set to 1000. When the form loads, the timer starts ticking. As soon as the current DateTime matches the value of the variable, it shows a message in the label. When I'm writing the following code, the values don't match even if the current system DateTime is equal to the variable. Label1 isn't showing 'Times Matched':[code]The default format of 'Now' is the same as I have stored in dtmVar variable. So there's no question of format mismatch. Does that mean 'Now' is not actually a DateTime property? Provided, my O.S. is Windows Vista Ultimate and all date/time settings are set to default.

I've seemed to found some interesting behavior with the stock MonthCalendar control. I've set the MinDate property to 1/1/1990 but when I try to actually select a date anywhere previous to 1/1/2000 it jumps to 12/31/2999 why is that?
I've tries manually setting it to 4/8/1998 and it jumps to 4/8/2998 which isn't what I would expect a calendar control to do. Is there a reason it keeps it within the 21st century?

How can I ensure that my program function can only run once a time per day? I wonder how did those commercial software that did something like 30 times/days trial. How did they store the value in the sense that altering the system date and time would not prolong the trial. Currently I am thinking of validating the date through internet time since it can't be alter by user. After which, I will store the value online. However, this does not seems to be feasible if its an offline application. I wonder is the any other better way to do it?
