In VB.NET: If varShort is a Short and varBit is a value from 0 to 15, how can I set the bit in varShort identified by varBit without disturbing any of the other bits in varShort? My problem, of course, is with the most significant bit, bit 15. Since varBit is determined at runtime

I want to bitwise turn off the left most bit of a Short value (&H8000) and leave the other bits as they are.
Dim x = BitConverter.GetBytes(Short.MaxValue Or &H8000)

Isn't there any shorter way with bitwise operators?

View 1 RepliesI have a date field in my Access database that I want to display in a textbox with a colored back color. This is VB.NET 2008. A datetimepicker has a format property (short) but the datetimepicker does not allow the color I want. No problem, it's just for display so I'll use a textbox. But the textbox shows the date and time. How can I get rid of the time in the textbox and just have the date? The field in the Access table is Date/Time with a format of Short. I think Access always stores the time.

We had a Nullable object must have a value error today on this line of code:list = From x In Me Where x.FooDate.HasValue AndAlso x.FooDate.Value.Date >= barDate
Funny thing is that I feel sure this used to work fine (and there has always been a sprinkling of null values in the underlying data). And logically it looks fine to me. The check for HasValue and the AndAlso look as if they're going to shield us from any Null danger.But it seems suddenly they're not. Am I missing something?OK, we can correct it to this, which eliminates the error:
list = From x In Me Where If(x.FooDate.HasValue, x.FooDate.Value.Date >= barDate,False)
But this looks to me less readable. In simplifying the above code to shorten the line I left out a crucial chunk of the code. The original problem should have read something like:
list = From x In Me Where x.FooDate.HasValue AndAlso x.FooDate.Value.Date >= fromDate And x.FooDate.Value.Date <= toDate
Because of the rules of shortcircuiting and operator precedence (as outlined in an answer to a long ago question of my own) I needed to add brackets round the second part of the instruction in order to stop LINQ evaluating the second x.FooDate.Value.Date:
list = From x In Me Where x.FooDate.HasValue AndAlso (x.FooDate.Value.Date >= fromDate and x.FooDate.Value.Date <= toDate) LINQ really does obey AndAlso and force me to look more closely at the original problem.

I'm building a new web app that has a requirement to generate an internal short URL to be used in the future for users to easily get back to a specific page which has a very long URL. My initial thoughts are to store a number in a database and output it in a HEXADECIMAL value to keep it shorter than an integer. TinyURL.com seems to use something other than HEXADECIMAL (multiple case letters mixed with numbers)
