How can I add a unique search button which looks in a specific file?

Posted By:      Posted Date: April 10, 2011    Points: 0   Category :C#
I would like to add a search bar to our Sharepoint Site that will allow people to search a specific document (or documents) I have loaded onto our Sharepoint site. Basically, the people will be searching for Account Names and the results will return an Account Manager.

Code Name WinFS: Revolutionary File Storage System Lets Users Search and Manage Files Based on Conte


One of the monumental problems organizations face today is aggregating information that's stored in disparate formats. Knowledge workers have long wanted to be able to search for content independent of format. The next version of the Windows operating system, code-named "Longhorn," boasts a new storage subsystem that makes that task easier. That subsystem, code-named "WinFS," allows the user to perform searches based on the metadata of the stored item, regardless of what type of file it is or which application created it. This article covers the basic architecture of WinFS and explains how to use the WinFS managed API.

Excel file not showing in search results

We have a strange issue. I have one Excel document (or at least one that I am aware of) that will not show up in search results for content within the document. I can find the document by title just fine, but when I search for words within the document I do not see it. The document was originally a 2003 Excel document and was recently converted to 2007. Other than that there isn't really anything unusual about it (some formatting stuff, but mainly just background colors and whatnot, nothing fancy). The crawl log shows the document was crawled without error. Anyone know anything else I can check on?

Problems creating a BDC file that use a unique select statment


I'm trying to build an BDC file that will pull information back from two tables in an Oracle database, I can import it without any errors, but then it tells me I do not have a filter when I try and select an item.  When I add a filter I get an error when I import the file.  The error I get is the following.
"Application definition import failed. The following error occurred: The IdentifierName Attribute of the TypeDescriptor named 'TestDate' of the Parameter named ':TestDate' of the Method named 'Get_TestTwelve_List' of the Entity named 'TestTwelve' does not match any of the defined Identifiers for the Entity. Error was encountered at or just before Line: '133' and Position: '16'."

how to automatically save new file into document library with a unique name or ID?

I've created a form using MS Word Document (2007) and lock it (protect it) so that users will be able to fill in the required fields.
then i've created a Content Type and uploaded the MS word form to be used as a template.

Then I've created a document library and enabled the content type and associate the above form for the library, so that when users click on New button the form will open.

everythings goes fine till here.

The problem is when users clicks on New and save the file back to the library, It doesn't save it with a unique name, instead it is over writting the existing one.
in other words, if employee 1 fill up the form and save it and later on employee 2 accessed the library and fill up a new form, he will overwrite what employee 1 has already saved!!

Is there a way to give every new created file a unique name? maybe (username+time)??

gridview filtering using a codebehind (textbox + search button)

i am trying to replicate the following sequence: input text into text box > press search button > search a database using LIKE operator > display using a gridview or listview. this sequence is fairly easy to do using the drag and drop then sqldatasource options, but i am trying to do the same result using a codebehind.  here is my code:   ____________________________________________________________________________________________________________ SqlConnection myConn; myConn = new SqlConnection(@"Data Source=.\SQLEXPRESS; AttachDbFilename=|DataDirectory|\projectDB.mdf; Integrated Security=True;User Instance=True"); myConn.Open(); string strSQL; strSQL = "SELECT * FROM Message";       //strSQL = "SELECT * FROM Message WHERE Message LIKE '" + txtSearch.Text + "'"; SqlDataAdapter da = new SqlDataAdapter(strSQL, myConn); DataSet ds = new DataSet(); da.Fill(ds, "Message"); GridView1.DataSource = ds; GridView1.DataBind(); myConn.Close(); _____________________________________________________________________________________________________________  now, if I use this code inside a page_load event, it does work. if I put it inside a button_click event i get nothing. i am mystified by this.. any help? why can't i use a button to display my gridview1 when i'm using a code behind.  

File search - Asp.Net 4.0

Hello everybody. I am developing a new project to list files and directories under an specified location on disk. I use normal methods like Directory.GetFiles() to achieve this task but the amount of files is getting very big (> 300000) and the site is becoming terrible slow. I worked with Index server with previous versions of Asp.Net but I was wondering if there is a new way for my website running Asp.Net 4.0. Also I heard something about Index Server is obsolete to achive file listings and search. Is there any new alternative? Many thanks

Where is the document library setting "Unique file names"?

Live can be so simple if only… ;-).   When using DMS functionality unique file names must be possible. The name is an unimportant attribute when using Meta data. So why can I not choose somewhere in the document library settings something like:   ·         Generate unique filenames Or ·         Do not allow overwrite existing filenames   Maybe in the first service pack?   MS? Please, please, please

Build xml file from gridview values on button click

We are looking to add GoogleMaps to our application. With that said we are going to be using the geocoding api to pass in the lat and long values to pin point locations on the the map. Reading thru the documentation we can pass in the values via XML, so we would like to see how we can take the lat and long values from our gridview and pass that to the API if and when somone clicks on the button to show the map.. The process will work like so, you arrive at the search page, you complete a search, in most if not all cases, you will always get multiple results presented in a gridview. If you should to view them all on the map, you click button and it needs to map out each location on the map. So is there anyway to pull from the gridview the lat, long and description to pass into the API?   Any links to sites that i can review would be great. thanks.

Execute a SSRS Report from CRM using URL to output to PDF with a specific file name


We have a CRM installation from which I am trying to do some reports which use the CRMAF filters so the reports are sensitive to entitiy selections.

eg execute a sales report for a number of selected accounts.

The specific RDLs have been created in VS2008 and uploaded to the reporting server via the Report import tools within CRM and all work as expected however the output of the report is in HTML via the web browser.

I have changed the configuration of the report in CRM so that it uses the URL method like below so that the report is rendered into PDF which is great.



This method prompts for the user to open/save the PDF file which is acceptable however I would like to replace the default file name (which is the report name) with one of my own.
