C# - Windows Desktop Search - Force Re-index / Index Now From Command Line?

May 14, 2010

I'm working on a project where we're using Windows Desktop Search (WDS) to index files on a web share and then later allow the user to search via a website for documents in the share.

These documents are transferred to the share via FTP, however it would seem that either the computer never goes idle to index or at some point the indexing stops. Is there a way from the command line or within the program itself to force this to happen without having to re-invent the wheel? Using .NET 3.5 and C#.

JavaScript - Get The Active Index Of The Jquery Accordion Pane From The Server-side

Jan 27, 2010

How can I get the active index of the jquery accordion pane when a button is clicked? What I want to do is when a button is clicked in pane 3 for example, I want to store that value and when the page is reloaded, I want pane 3 to remain open.

I intially had this in my server side click and when I hard code a value in for paneIndex it works fine, but obviously, I don't want to do this, I want to get the index on the click and pass that to the script.

string script = "<script type="text/javascript">var paneIndex = " + 3 + "</script>";

if(!ClientScript.IsStartupScriptRegistered("JSScript"))
ClientScript.RegisterStartupScript(this.GetType(),"JSScript", script);

SQL Server :: For A Full Text Index, What Is The Difference In These Types Of Population Schedules?

Oct 11, 2010

I am using SQL2008 and created a full-text index on 1 of my tables. Going through the wizard, I was offered (2) types of population schedules as follows:New Table Schedule: Define a population schedule for a table.New Catalog Schedule: Define a population schedule for a full-text catalog.I am familiar with a 'Catalog' schedule for population which I do nightly and was similar to configuration on SQL2000 for a full text index. However, what is the difference for a 'Table' schedule vs the 'Catalog' population schedule? I have the definitions above, but if someone with knowledge could offer a better in depth explanation in comparison, and if I should use both or not (I have just a Catalog population scheduled currently),

SQL Server :: Finding Spatial Index Settings For Geography Data Type Column?

Aug 9, 2010

I have a column in SQL Server 2008 called MapLocation which is stored as the geography data type. This column is used to store the location of a building in one table, and the location of landmarks in another table. I have to list all landmarks within 4 miles of a building.

I have a clustered primary key on an automatically generated int column in each table. I assume that I need to create a spatial index on the MapLocation column in the landmarks table. This I guess would aid finding all landmarks within 4 miles.

My problem is that I am not sure what settings to use for this spatial index. I have set the spatial index to have the following settings:

Cells per object: 16 Level 1: Medium Level 2: Medium Level 3: Medium Level 4: Medium Tessalation Scheme: Geography gridAre these the best settings? Am I doing the right thing?

C# - GridView.Columns[index].HeaderText Throws "Index Was Out Of Range" Error?

Jan 3, 2011

gvOff.DataSource = o.ViewData(dCity.SelectedValue);
gvOff.DataBind();
gvOff.Columns[0].HeaderText = "ZZZZZZZZ";
gvOff.Columns[1].HeaderText = "YYYYYYYY";
gvOff.Columns[2].HeaderText = "XXXXXXXX";

Header count is correct.

AutoGenerateColumns: Flase/True ( i tried both)
If i remove the gvOff.Columns[index].HeaderText portions, GridView works fine, but when i put the gvOff.Columns[0].HeaderText, i get the exceptional error.

, i couldn't solve it. If you need further info, inform me.

EDITED:

Hold on! I commented the HeaderText portion and tested
int i = gvOffer.Columns.Count;
I found count is 0 eventhough the columns print out with DataBind()... Why?
NOTE: AutoColumn in this case is set to true. I guess i will have to edit the column
names from DataTable.

DataSource Controls :: Queries In SQL Server - Decide When To Use Clustered And When To Use Non Clustered Index?

Feb 18, 2010

1) we have only one select query to select 5 column form the table(i.e. select col1,col2,col3,col4,col5). so in that case should we go for stored procedure Or we can directly write the select query in the .Cs file only ( means in Database layer). when we should go for the SQL server stored procedure and when we should go for in line query in Visual Studio itself.

2)how to decide when to use Clustered and when to use Non Clustered index?

C# - Save A Binary File In SQL Server As BLOB And Text (or Get The Text From Full-Text Index)?

Mar 26, 2010

Currently we are saving files (PDF, DOC) into the database as BLOB fields. I would like to be able to retrieve the raw text of the file to be able to manipulate it for hit-highlighting and other functions.Does anyone know of a simple way to either parse out the files and save the raw text on save, either via SQL or .net code. I have found that Adobe has a filtdump utility that will convert the PDF to text. Filtdump seems to be a command line tool, and i don't see a way to use a file stream. And what would the extractor be for Office documents and other file types?-or-Is there a way to pull out the raw text from the SQL Full text index, without using 3rd party filters?Note i am trying to build a .net & MSSql solution without having to use a third party tool such as Lucene
