Hello, We 've got a strange issue with the search and especially with the FileExtension metadata. when we make a query on the search engine, we receive for the FileExtension metadata an unexcpected result. here is a printscreen showing the issue. http://cid-53eee937847a625e.photos.live.com/self.aspx/Public/Untitled.jpg as you can see the Type of the FileExtension is object and it should be string and I checked the type of the object and it's System.String[] the element at the index 0 contains the value! what's wrong ? thx in advance

Unable to cast object of type 'System.DBNull' to type 'System.String'.

  

 I saw lots of post about this issue. but haven't got good solution for that yet. Basically, what I did is that: I have a table in SQL database and some of data fields allow null. I built Objectdatasource through dataset. When I built update page using dataset. It generate the following error before showing the update page correctly. It seems I have issue to retrieve the null value from the database through using objectdatasource through dataset. Any suggestions?

When i'm trying to update a table using dynamic data, i'm getting the following error. I was trying to google the solution for the whole day, but it didnt work. I tried to declare the type of parameters like this

                onselected="DetailsDataSource_Selected"
                onupdating="DetailsDataSource_Updating" > <UpdateParameters><asp:Parameter Name="PK_ID" Type="Int32" /><asp:Parameter Name="id" Type="Int32" />
                <asp:Parameter Name="c_titulu" Type="Int32" />
                <asp:Parameter Name="perio" Type="Int32" />
            

type object parameter

  

Hello!

I have a problem I can't figure out.

I've been trying to add a listbox with multi select enabled as a parameter to my select statement in sqldatasource.

So i created a function like this :

string strItemTypes = "";
foreach (ListItem li in lbItemType.Items)
{
   if (li.Selected)
   {
      strItemTypes += "," + li.Value;
   }
}
strItemTypes = strItemTypes.Substring(1);


which gives me the selected items like this for example : "1,2,3"...
Then I've been trying to add it to my sql select statement :


SELECT tblOfficesItems.idOfficesItems, tblStockItems.Name, tblStockItems.Description, tblStockItemTypes.TypeItem, tblStockItems.Notes FROM tblOfficesItems INNER JOIN tblStockItems ON tblOfficesItems.fkItem = tblStockItems.idItem INNER JOIN tblStockItemTypes ON tblStockItems.fkTypeItem = tblStockItemTypes.idTypeItem WHERE tblStockItems.fkTypeItem IN ( @fkTypeItems )


using a hiddenfield with a controlparameter of type=object
but it just don't seem to work, seems like the data just won't bind or something and I don't get any errors so I'm confused!!

then i tried this :


SELECT tblOfficesItems.idOfficesItems, tblStockItems.Name

Search for a string in my datasource dynamically

  

I am displaying an Rssfeed on my page by using XmlDataSource and Datalist controls.

I want the user to be able to limit the information that is returned to my datalist.  To do this I have a textbox on the form that allows the user to enter their search criteria.

I need to be able to dynamically create a query string utilizing the information that the user entered in the textbox.  I am also using a drop down list and allowing the user to select whether they want to search in the title, description, or all parts of the xml file.

I am having trouble figuring out how to reference the data contained in my textbox in my query string.  Where the query string says 'asp', I want to replace 'asp' with the content from my sSearch variable.  Can anyone tell me how to reference my variable in the query string???

string sSearch = txtSearch.Text;
        string SQuery = "";

        if (DropDownList2.SelectedIndex == 0)
        {
            SQuery = "[contains(title), 'asp')]";
            
        }

Conversion from string to type 'Date' is not valid

  

Hi

Im receiving a strange error Error Message: Conversion from string "15/08/2010 22:21:35" to type 'Date' is not valid.

I know this is generally down to cultural date formats etc, however the reason this is strange is it just randomly occured twice in the last week, the website has been running since october and nothing has changed,

The error constantly occured until the IIS was reset and recompilled the site, its been running fine since, however im just trying to figure out what could cause such an error to occur.

I've narrowed it down to a line of code which is:

bktime = DReader.Item("Bktime").ToString

bktime = Year(CDate(bktime)) & "-" & fmt(Month(CDate(bktime)), 2) & "-" & fmt(Day(CDate(bktime)), 2)


Has anyone else encountered this randomly occuring and is there anything i can put in place to prevent this in future?


Cheers

implementing a search similar to what you have in google when you type in a word

  

Dear all;


I have a textbox and what I would like to implement is basically a situation similar to what you have in google when you type in a word. In otherwords,


in the textbox when you type in J, it should generate a list of names that starts with O in alphabetical order, then next when you type in o, so that now you have Jo, it should generate a list of names instead that now starts with Jo in alphabetical order, then again when you type in h, it should generate a list of names that starts with Joh and so on. A sample code could be helpful. Thank you. No Javascript of Jquery please. All help will be greatly appreciated.

How can I prioritise search results to show where document metadata has a hit first and then where t

  

When my users run a search against a site with a bunch of document libraries they will often search for terms that are in the title of the doc, if they do know the title they will put that in. What I would like to do is have the results ordered such that if any hits are on the document metadata (eg Title) then they are presented first and any results that are from hits on the content of the documents are presented later.

So, if they get the title spot on in their search query that document will appear first .... if they don't get it right then the likelyhood is that the title is something like what they entered so similar titled docs are presented first and then those with matching content ....

How can I achieve this?

 


Search Server Gatherer - Custom hierarchical protocol handler ISearchProtocol for MOSS 2010

  

Hi,

Search server gatherer calls CloseAccessor() and shutdown() on ISearchProtocol after GetChunk() even if the FILTER_E_END_OF_CHUNKS is not returned. After calling shutdown() it stops calling the createaccessor() with new URL. I want to create a hierarchical indexing but I am not gatherer is not suporting this. The same piece of code is working fine in MOSS 2007, I am facing this issue in MOSS 2010 only. Is there anything changed in MOSS 2010 which is creating this issue?

Thanks,

Issue with List Definition of same base content type and deployed via same feature

  

I am trying to deploy two custom list definitions using only one single feature.  Below are the details of my issue.

  • Two custom list definitions
  • Each custom list definition has its own custom content type
  • Each custom content type inherits from the base content type Picture (Type = 109)
  • The custom list definitions are grouped together under one single feature
  • The custom content types are grouped together under a seperate single feature

When I deploy my solution in this configuration, the second list definition gets the first custom content type applied to it and the list schema from the first list definition is also applied to the second list definition.

What makes this more interesting, when I seperate both of the list definitions under two seperate features it all works fine.  Custom content types and list schemas get applied correctly.

Can anyone tell me why I can not deploy both list definitions under one single feature?

If you need me to post any of the origional code or XML to this post please let me know.

 

Craig
