Flatten An XML File To CSV Format?
Feb 4, 2010how to flatten an XML file to CSV format. I have worked on this all day today, and although I've found some simple examples, my issue is slighlty different. Please see example below...
[code]...
Notice that the data node has several different structure of child node. Is it possible to write XSL to flatten this?Second question is it possible to write the XSL in a generic way so that it doesn't need to be aware of node names and therefore just works for any XML fed in?
How To Best Flatten A Tab-delimited Table
Aug 3, 2010Here's an example data table (the data are fake, but in the same format as my business data coming from an external system):
R1 Pears,Apples,Bananas 10
Oranges 5
R2 Apricots 15
[code]....
The data are in a string. Columns are tab-delimited, lines are CRLF-delimited. Output should be the same. Multiple values are comma-delimited.
Here's the "flattened" output desired:
R1 Pears 10
R1 Apples 10
R1 Bananas 10
[code]....
Each column is filled down where there are blanks, and columns with multiple values (comma-delimited) are duplicated and filled down in the other columns.Complicating assumption: the number of columns in the input is arbitrary.Simplifying assumption: only one column will be comma-delimited.I'm working through this with a relatively naive solution (loops and some recursion), but I'd love to see if this is a situation where LINQ or some other solution would be more appropriate.I'm working in VB.NET at the moment, but C# is fine too.

View 1 RepliesFlatten A Dictionary Of Dictionaries And Sum The Values Of The Inner Dictionary With LINQ?
Apr 16, 2012I have the following object:
countDictionary As Dictionary(of Category, Dictionary(of Date, Integer))
The Class has a Enumeration Property. For the purposes of demonstration, I'll call it MasterCategory.I have been trying to get out an object that looks like the following:
groupedCountDictionary As Dictionary(of MasterCategory, Dictionary(of Date, Integer)
The best result I could get was:
Lookup(of MasterCategory, Dictionary(of Date, Integer))
From:
countDictionary.ToLookup(Function(o) o.Key.MasterCategory, Function(o) o.Value)
Which results in a IEnumerable (Of Dictionary(of Date, Integer)) for each MasterCategory value.However, I need that IEnumerable of Dictionary flattened to one dictionary with all the integers summed (total counts) for each date. I then tried to use various selects and group bys (from numerous stackoverflow posts) to "flatten" it, but my efforts have fallen short.
Current Code

- MasterCategory As Enum
- Name As String etc

Importing Data From Excel To Datagrid Or Datagridview?
May 5, 2010I have a problem loading big spreadsheets into a datagridview.
I had a similar code as above that i used and it works great if you have say 10000 cells to populate cell by cell.
How ever moving to 2 mil cells is a different cup of tea, the code took more than 7 minutes to load the data, and although the data was perfect in every way, its too time consuming, i cant get it to work faster so I used the datagrid instead.
The sheets needed to be imported is 350,000 cells plus. I used code that works realy great, does the import into the grid and transfers the data to a datagridview within 15 seconds with little resources which put a smile on my dail :) then i saw something and it dropped ...
see code:
[Code].....
My problem is that whenever there are values below the heading of the cell the datagrid displays (null)
No matter what i do even converting the values in excel to text it does not display the heading of that column.
When i paste other text into the cells below the heading (NOT NUMBERS) it shows the data and heading, Only if the "type" of content is the same does it display both the heading and the text that follows in rows below.

VS 2010 Generating Xsd File (Using DataGrid Not DataGridView)
Mar 30, 2012Major problems with the Schema. I am using the DataGrid and not the VB Express 2010 DataGridView. Using code to make a new DataSet and DataView. What is confusing me is when adding Items after right clicking the application in the Solution Explorer, the add items shows DataSet, Xml To Schema, and Xml File. It is obvious that I don't know how to generate an xsd file that I can read into a code generated DataSet. If someone is familiar with xml and VB Express2010. how to generate an xsd file using DataGrid instead of DataGridView that I can read into a code generated DataSet?

View 2 RepliesDatagridview - Sort Datagrid View Column With Numbers And Texts On Column Header Click?
Feb 13, 2012It seems that on clicking datagridview column header, the column will be automatically sorted based on the column type. I have a column showing some numbers. If column type is string, it sorts "1","20","3" into "1","20","3". If column type is double, it sorts into "1","3","20" which is the result that I want. However, there might be some erros in the numbers and error messages(text) will show in the cell instead of numbers. So I cannot set the column type as double. I want to ignore these error messages and sort all the numbers. How can I do this?
Also, I need to add some background colors to different rows in datagridview. So in the column header click event, I call the bkgColor Sub to achieve this. My question is that how can I override the sorting method in this event?

Datagrid Control - Fill And Use Each Datagrid Indepentent From Each Other?

Dynamic DataGrid - Dynamically "transform" DataGrid To Display The Selected Search Template
May 23, 2011I have a search form on that will be pulling search template queries from a table in the underlying (an Access db on a share). The search form has a calendar control for filtering by date range, a listbox containing the names of the search templates, a second listbox which lists the fields in the selected template, and then some controls which show/hide themselves depending on which field is selected so that the user can pick a field and enter it's unique criteria in the appropriate control for filtering. Below these controls is a DataGrid, which will obviously display the results.
The problem is how to dynamically "transform" this DataGrid to display the selected search template. These templates do not represent tables in the underlying; rather they represent preconstructed SQL queries (stored in a table) which are essentially SELECT queries with joins and no WHERE clause (so they are the results of multiple tables joined together by their keys).
To be honest, I'm having trouble even generating the LINQ queries to represent these template dynamically, but that's not as important, since I can manually translate the SQL queries into LINQ. This is definitely not the preferred method, as the whole point of putting these templates in a table, rather than code, was to allow for future additions without rebuilding/redistributing the application interface.
