Lamba Expression To Select All Values Between Lower And Upper
Nov 19, 2010lambda - vb.net lamba expression to select all values between lower and upper values plus the next lower and upper value. I need some help with a lamda expression to get a subset of range of values. I have a lower and upper value, and getting everything between them seems easy enough, but I also need the next lower and higher value to be included. I can do each of these separately, but would like to do it in one shot if possible.
The range I need the subset from has 150 values. A small example would look like:
{8.206,8.206,8.201,8.196,8.193,8.192,8.189,8.174,8.171,8.171,8.166,8.163,8.157,8.154,8.153,8.14,8.131}
My lower value is: 8.16
My upper value is: 8.17
I need to get back: {8.171,8.171,8.166,8.163,8.157}

Select Query From One Datatable To Another
Nov 20, 2011I have pulled information from a database into a datatable (dtCustomerInfo) then I expanded on the columns by processing the data and I can display this in a datagridview without any problem. However, the data is in detail and I want to ultimately summarize by customer name.The code below has a commented sql statement that is the statement I ultimately want but it is not working. However, the idea is that I want to Select from one datatable into another but run aggregate sum on several columns so that I will get one record per customer showing totals for each column.So I broke it down to just pull all data possible into the second table.[code]I do know the grouping in the current select * statement does nothing but my issue is more that the columns do not show up.

Select On Datatable With Order By And Clear When Done?
Jun 11, 2010I am working on a vb.net app for a handheld using Windows CE and I have a few columns of data loaded in a datatable from a text data file. Some of the records can have duplicate Account IDs so I cannot use a primary key. What I want to do is take an Account ID entered and filter on just those records. I need to loop through all records with this Account ID, make updates to any of them and then clear the filter.
how to set a filter on a column based on a given string such as an account number? And loop through these records? Can I modify the records at that time?
