I'm fairly new to VB and am having trouble implementing the Round function. I know that the syntax for what I'm trying to do is:document.write(Round("KwH",2))But my problem is that I can't get it working with the following line:.Kwh = items.Attribute("KwH").Value _So I want the output of whatever 'KwH' spits out to have only 2 decimals, despite the actual figure having 8

im trying to implement a search function to my booking program, wich retrieves data from a SQL database. I have the screan all set up and all the variables at the ready, the only problem is, im not sure how to execute it in a sqlcommand line.
I've got all the fields that are required, such as date, time but i also have two optional options, Room Type and Room Capacity.
How would i write a sqlcommand to search for available rooms that meet the criteria for the room to be booked?
Heres the code i have so far;[code...]
I was wondering if someone could explain the logic behind the MidpointRounding enumeration for the Math.Round function. The two enumerations are AwayFromZero and ToEven where, based on the given precision, the former will return the nearest value away from zero toward positive or negative infinity (based on the value's sign) and and letter will provide the nearest even number.

I need a function which will Round a number UP to the specified decimal precision, exactly the same as how Excel's RoundUp function works:
Roundup(dblVal, intDecPlaces)
So I need the following:
Roundup(0.896523, 4)
would return
0.8966
However, everything i've tried/found simply rounds to the nearest whole integer, or returns a normal rounded value, hence the above would return
0.8965
I've tried the following:
Math.Round(dblval, intPrecision, midpointrounding.awayfromzero)
' and
Math.Round(dblval, intPrecision, midpointrounding.toeven)
And even custom functions, such as:
Public Function RoundUp(ByVal varValue As Object, _
ByVal iNum As Integer) As Double
'ignore the data types here, I was playing to see 'if changing any of the data types would swing 'the results (knowing full well they wouldnt make 'a difference, thats how fed up with this I am!)
Dim lNum As Long, xVal As Double, xVar As Object
xVar = Fix(varValue)

I've even looked at converting this to a string, looking at the Xth decimal place, and incrementing it up by 1, then converting it back to a double, while this works (sort of) it seems to be a very roughshod way of doing it, and I'd rather do it mathematically than with lots of data conversion.
this wont be easy to explain clearly but here goes..i have something that works fine in VB but not in C#.i have 2 classes, each class implements a different interface. each interface exposes an Initialize() function that should get called automatically when the plugin loads. since each class has an Initialize() function, i can watch both functions get called in the log. this works fine in VB.
when i do this same thing in C#, only the Initialize() in the first class gets called. anyone have a clue as to why this might be happening?

as you can see the code is identical in both languages. why does it work in VB and not in C#?
I've decided to make my own simple scripting language parser. I've created about 50% of it and it works great! I need to implement "functions". What ever program uses my parser needs to be able to connect functions to my parser for customization. I've implemented "Lua", a scripting language, in a vb.net application of mine. To connect functions to the Lua Parser it used reflections.I need to be able to (by only knowing the name of the function and its structure) call a function connected through the implementing application.
View 2 RepliesI wrote a serializer (to Byte Array) for dictionaries that have a string key, but an object of some sort as its value.I've never implemented a generic type in a function or used a delegate before, so I'm a bit concerned about this being significantly slower than writing a serialization function for a specific type of Dictionary (Dictionary(Of String, MyClass) for example)Should this code be significantly slower due to the use of the generic type or the delegate?
[code]...
It works, and I could loop it and compare it to a more static Dictionary serializer, but I'm more concerned about when I start using this for a lot of different String/Object dictionary combinations, and it'll take me a long time to write a bunch of static dictionary serializers (that's what I'm hoping to avoid in the first place)edit: simplified intro text
I am working in excel trying to setup a function involving multiplying a cell by a set number and then having the result round to the nearest 10. Here's the beginning of my function statement fx=e3*1.026. say the result is 8654, I need it to round to 8650. Also if it comes back 8655, I need it to round to 8660. I have about 2,000 records I need to do this to so I was hoping that one formula or statement could be used for all my data.

I need a function in VB.Net that is round up the value to the next quarter.Example value 0.26 should become 0.5 and 0.51 should become 0.75,etc.Excel has this function standard like RoundUp(value;0.25). But I my opinion this function is available in VB.Net. Is there an easy way in VB.Net to calculate the next quarter.
