C# :: Program Design - Database Search Engine

Apr 12, 2014

I am building a semi-complicated program and the focus of it will be on the search engine. The current plan is for it to search an online database after keywords and receive a list of responses organized by relevance.

I want to minimize the stress on the server by handling as much of the process on the client side as possible so I wonder how best to split up the tasks.

So far my idea is to have the client send the search term to the server who then compare it with its registry. Collecting the 30 or so most relevant hits it sends it back along with additional information from each entry. Requesting additional hits will be decided by sending a simple int value telling which page its filling up.

Simple example:

"Search word" gets processed by the client to account for spelling errors, context etc (based on what I can implement by myself). An Int value gets added (0 for page 1, 1 for page 2 etc...). The request gets sent to the server who can immediately run the search without processing the search word since that was handled in the client. It locates hits and order them by relevance then send out the information batch decided by the Int.

C Sharp :: TreeView To Database Or At Least DataTable

Feb 8, 2014

The main question how to fully traverse/circumvent through all TreeView, for transforming Tree structure into a Table structure.

I want to note that the TreeView may contain a different number of branches, with different depths and different names.

I found a lot of information how to populate TreeView e.g. from DataTable, but I didn't found information how to recursively traverse/circumvent a TreeView and populate/fill data e.g. to DataTable.

As sample I have following TreeView:

Aaron
-Baldwin
--Caleb
---Dale
--Earl
-Fabian
Gabriel
-Harold
-Ian

Necessary to convert the TreeView into e.g. DataTable:

id | Name | ParentId
--------------------------------
1 | Aaron | null
2 | Baldwin | 1
3 | Caleb | 2
4 | Dale | 3
5 | Earl | 2
6 | Fabian | 1
7 | Gabriel | null
8 | Harold | 7
9 | Ian | 7

C Sharp :: Access Database Is Copying To Output Directory On Its Own

Oct 4, 2014

I have an extremely annoying problem, I am inserting data into an access database and now i have noticed that it is copying itself to the bin/debug folder on ts own and yet i have set "Copy to Output Directory" property to "Copy never"

But without fail, it is copied! It is making any attempted updates to the database's information invalid since its not updating at all.

This all started when i installed crystal reports and it asked me to make a duplicate of the database in order to utilize data-sets that were created for certain reports.

Why this is happening? I cannot test my application properly at all.
