In the discussion in this thread: [URL] it was reveiled to me that vb.net, using double, could only calculate values up to 18 digits after decimal.... so I started thinking and came up with this class
Public Class LargeNumber
Private pNumber As String
Public Sub New()
[CODE].............
I want to split the string into a series of doubles.... and than combine them into a large number.... The size of each double component should be 18 digits on a 32 bit computer... so that I will have room to add the last carrier...

I have a DEM file(Digital Elevattion Model File) and I am trying to open the file,where we have Latitude and Longitude values inside the DEM file.And, Now I have opened the file using Filestream and Read the file using BinaryReader.But, I am having a trobule in getting the values of Latitude and Longitude.I am getting Byte values randomly as 1,202,31,271 etc.But, we dont have latitude and longitude values more than 180,and also I am not getting 16 bit UInt values.For example, the values should be like Latitude 20.00416666666667 and Longitude 39.99583333333333.So,read the correct Byte values of the DEM file.The code I have used till now is:
Dim fs As FileStream = New FileStream("C:UsersadminDesktopHeader and DEM fileE020N40.DEM", FileMode.Open, FileAccess.Read)
Dim rd As New BinaryReader(fs)
Dim convertDB As UInt16
For i = 0 To rd.BaseStream.Length

lets say I have a form (form1) with lables a-z which are all designed with default text "0". So they all show 0 on program startup. which is fine. I also have a dialog with 2 TextBoxes; I want my program to update the default text/value on (only)form1 labels x, y and z to whatever was put into the textboxes when i press the OK button on the Dialog, so these specified labels show the 'new' value on next startup. Is it even possible or should I save the values to a file which loads the values in the specified labels on startup?
View 5 RepliesI have simple columns and their respective sums. However, I exclude 1 particular value from each sum, like so [code]...
Now I need to exclude another value ("Awaiting Progression") from a second column called "PROGRESSION".
Since I already exclude value based on 1 column called CATEGORY, how do I change my =Sum(Code.ExcludeOthers(Fields!CATEGORY.Value,Fields!ACTION_PLAN_NEW.Value)) to exclude a value from the PROGRESSION column if it's = ("Awaiting Progression") ?
i.e. How do I exclude multiple values, depending on values in 2 columns in SSRS 2005?
I want to be able to see if the values a user inputs into 2 textboxs equals the values assigned to a picture. I put these values in the picture's name and tag. Also the picturebox is getting the image from a random function correlating to an imagelist. How would i go about thisI thought of maybe using a checkbox and coding
If picturebox1.image.tag = ("12") _
and textbox1.text = 1 _
and textbox2.text = 2 Then
checkbox1.checked = true
unfortunatly when i debug it says the picturebox1.image.tag = Nothing

View 4 RepliesI am using Visual Basic express edition 2008.I am trying to know if a value in a single dimensional array is repeated in the array. If yes, then multiply one of them by 100. For example:
MyArray (14) = 12, 15, 18, 15, 18, 11, 15, 18, 16, 14, 18, 8, 12, 17, 10
In the above example:
MyArray (1) = MyArray (3) = MyArray (6) = 15
MyArray (2) = MyArray (4) = MyArray (7) = MyArray (10) = 18
MyArray (0) = MyArray (12) = 12

then have to find the mismatched data and find difference with that values of mismatched data.

View 6 RepliesI have a bunch of events with values (how many people went through a doorway). Each event is associated with a Date. There is no fixed period to the events .If no one comes through the door, no event is generated, but often multiple people can go through at once, so the value can be greater than one.
Sometimes events are minutes apart for a time, sometimes there is gaps of a few hours,
Using the Date class, is there an easy way to average my values over periods of time?
