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
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),
How i can make the normal search string to sql server full text search parse, because when we are user enyer search text "how to run windows schedule in C#", in database we have article to to this, but data not returning and sometime is say error in key word and etc.
I am using FTB on my aspx page. is there any way I can have Toggle Full screen feature in FTB, is this feature availble in FTB? it is available on TinyMCE, but I don't want to switch to TinyMCE since I am already using FTB in most of the pages in my application.
I am having with the a full text index I am developing for a product catalog. It does all work to a degree I am just seeing some strange things happening.
From the database side I have a Products table that is being indexed on both the PartNumber and Description columns because I would like the users to be able to search either or using the search function.
Problem 1:
whenever I use multiple words in the search I don't always get the results I am looking for, this happens most notably when I am attempting to say put in a full part number (which for in this case would look like "I 10-9.2")
Problem 2:
I am not 100% sure that this is the most efficient way of completing what I am attempting to accomplish here since I have 2 columns that I need to perform the search on
Here is an excerpt from the click even when the user clicks the search button on the page:
[Code]....
And here is the search functions called from the click event to firstly check if there are any results and the second to display the results in a custom gridview:
I created a simple search form which populates a gridview from sql server. I use 'contains' on a varchar(max) field which has a full text index. I find if I do a search for "Mexico Argentina", I get multiple results, which is good.One thing my sql server stored procedure is doing is inserting the word 'AND' between words. I do this because I want all words to be found. So if the user inputs "Mexico Argentina", I am converting that to "Mexico AND Argentina"But if I have even one 'noise word' in the search string, I get no results at all. For instance, there might be a sentence in my database table saying "I prefer Mexico to Argentina" but if I put that sentence in, I get no results at all. The database is seeing my converted string:I AND prefer AND Mexico AND to AND ArgentinaAnd finds nothing.I also have another form, which does a more advanced search that allows 'exact phrase'. If the user chooses 'exact phrase', then I don't insert AND anywhere. Instead, I surround his phrase with 4 apostrophes - 2 before the phrase, and 2 after.So now the database sees:' ' I prefer Mexico to Argentina ' ' (I've put a space between apostrophes here to make it clearer to view.Now I not only get no results, I get an error message.
I have a text box were people will submit a large amoyunt of text to a field in a database. The text is set out multi line in paragraphs with returns. When the text is saved to the database it saves it as a continuous line of text. how do i save and retrieve it with the returns included.
I am outputing a text file of 1s and 0s. I want to shrink the file so I'm going to convert it to ascii. Its going to be used on a clientside web application so I can convert it back to binary with some scripting later on.
So, I want to convert the string of binary to a string of ascii serverside in vb.net. I have spent much time searching the web for a vb.net solution, and, what a mess!! everyone thinks they know how to do it, but none of the solutions have worked so far!!
I have a few columns in the table. (E.g. Name, ID, Phone, Address, Father name) and I have a text box where user can type in and the system will show match result on the page. User will only key in Name and Father name in the text box. I do not want to implement a full text search or indexing.
3 6 3,6 36 363 i want to display column which contain "6" means
6 and 3,6 not 36 and 363
so i am using full text search:
use PMS go EXEC sp_fulltext_database 'enable' go CREATE FULLTEXT CATALOG pmscatalog go CREATE FULLTEXT INDEX ON PMS.dbo.emp_project ( empid Language 0X0 ) KEY INDEX PK_emp_project ON pmscatalog WITH CHANGE_TRACKING AUTO SELECT empid FROM emp_project WHERE CONTAINS(empid, '"6"')
I have created procedure for full-text search and it works in SQL Management Studio 2008 (SQL Server 2008 Express) but in Visual Studio 2010 not - I have error:Full-Text Search is not installed, or a full-text component cannot be loaded.I have read somewhere that only admin can use full-text indexes - so how I can use full-text search in VS2010 ?
I would like to do an attachment on my database but I lost the full-text catalogs file. Sql server won't let me attach the database without it. What do I need to do to overcome this issue? Is there a way to tell Sql Server to skip the missing catalogs? If not, how do I generate another full-text catalogs file to replace to lost one?
I have an input type, so a text box which has a browse button next to it. When it is clicked, the file that is selected has it's full path placed into the text box.
Where is the event! Now that I have the path to the file in the textbox of the input type, I want to load each line of this file into a textbox that is able to handle multiline text. I don't want the file to be uploaded to the website. I just want to contents of the file read and placed in a textbox all with one click on the browse button.

I'm trying to read the contents of a text file into a text box on my form. When I run the following code, nothing happens.
VB.NET Code: Protected Sub lbLogs_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs) Handles lbLogs.SelectedIndexChanged    For Each li As ListItem In lbLogs.Items      If li.Selected Then        Using sw As New StreamReader(li.Value)          txtLog.Text = sw.ReadToEnd           sw.Close()        End Using      End If    Next  End Sub
I populate the ListBox with ListItems and each ListItem's Value property holds the full path to the file. But, I removed all of that and just put txtLog.Text = "test" inside of the "is selected" block.
I want to save the text data that coming from the database into the Text files.Suppose if i have dataset that contains 10 rows then i want to generate 10 text files and each text files contains associated row data.Finally i want to save them in the folder.Mail all the text files as a compressed format like zip and send them to the user.

However with what i have coded below it always presents the message, i am using asp.net 2.0 with webmatrix.
I'm using the full-text feature on SQL Server 2008 RC2. Everything had been working well until today. I wanted to change the language for word breakers from Neutral to Slovakia. After I did that, I can't perform full-text search anymore. It simply give me no rows. I even deleted the old full-text catalog and created a new one and populated it, but it still gave no solutions. I tried to query dm_fts_index_keywords_by_document on my table and get only 1 row with a display term END OF FILE.
I´m currently programming a web search application in ASP.Net and having problem with full text searching. My requirements are:
1. Save a byte array from SQL server to word document as a temp file in a server side?
2. How to highlight the string I am currently searching in the Word document and return to the user the sentence with the highlighted string (like on Bing or any other search engines)? Is it possible to fullfill this requirement with full-text search integrated in SQL Server 2008?
