I'm trying to create an array of DateTime objects. I can't use a List.
DateTime[] dates
dates[0] = Convert.ToDateTime("12/01/2009");
dates[1] = DateTime.Now;
However, I get an error, stating use of unassigned local variable.
I know that Session is for a single user , and application is for multi user purpose.The Data in the application object is shared. Right? Then how can access the application data from an another client.
if My concept is wrong then what's right?
Our business case requires that a Start Time and End Time must be defined for each Organization involved in the business model. For example; some organizations have their working hours from 8:00AM to 5:00PM and others from 9:00 to 6:00PM. While creating a new Event on our calendar these should be queried from the database (StartTime and EndTime) and setting these as default. My questions are:
1) How should I save these times since DateTime requires a Date in front of it and there's no Time column format on SQL Server (Varchar? Number?). If using one of these types how to I concatenate these to a DateTime variable?
2) If the column should be DateTime, how do I concatenate it to replace the column's Date with Today's date and replace the Time with the time specified for that? Let me be more clear:
Default values saved in the database: StartTime = "2010-01-01 8:00AM" EndTime = "2010-01-01 5:00PM" In my code after querying, my local variables would be populated and replaced by: OrgStartHour = "2010-03-26 8:00AM" and OrgEndHour = "2010-03-26 5:00PM"
[Code]....
The code above works but I have no idea on how to replace/concatenate the "2010-01-01" with today's date while keeping the "8:00 AM" on it. :)
I am trying to check how much time does a function takes to execute in my code :
I did this :
void foo()

int time = System.DateTime.Now.Millisecond;
// code of my function. do this, that, etc.
Console.WriteLine((System.DateTime.Now.Millisecond-time).ToString());
}
What i get is this :
-247

Sometimes I get a datetime with a time sometimes it's just the date. Of course if it's just the date I I want to format with "dd.MM.yyyy" and if it has a time "dd.MM.yyyy HH:mm".. This is in a repeater, so I thought may be it's possible without a simple if statement?
View 3 RepliesI've read the MSDN page describing the Localize control and read about the difference between designers in the following link:http://my.safaribooksonline.com/0321341384/app01lev2sec53 Still, I can't find any visual difference between the Localize and Literal control in the designer view of VS 2010.I've tried using explicit and implicit expressions in an aspx and the designer looks the same for both controls - shows the neutral culture resource.I've looked at the LocalizeDesigner code in reflector and the only thing the designer seems to localize is the HTML format of the outputed span control, and that seems irellevant to the designer.Can anyone attach a short example that demonstrate when the two controls behave differently?

Should I store the DateTime.Now in DB as it is, or should I use DateDiff to change the time before creating each record?
What's the best practice here? What to store in the database? Should the date only be differed when presenting it?
