Some ids are pulled out from the XML field of a certain User Profile . Those ids have their text values stored in a SQL table.
What is the best way to map that xml list to the SQL table in order to populate a dropdown list which contains ids from the XML list and text values from the SQL table?
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
Is there such a thing? So for eample, on my image load I have the following hooked up to a table where "Image" is a binary image set of data.
protected void Image1_Load1(object sender, EventArgs e) { myent logo = new myent(); var query = (from p in logo.tblLogoes where p.Id == id && p.Id2 == id2 select p.Image).First(); return query. }
What do I need to return here to populate the image? I have funny feeling, it's not going to be as simple as that.
i am working on the mobile application, and i want to read binary file .. its just contains the string.. e.g "hi Wel come". I have opened that file using filestream and try to read that file using binaryReader.. but it didn't read that file correctly. if i use
binaryreader.readstring();
it throws an exception of endOfstream. when i stored that stream into array of byte and read it through response.binaryWrite.... like
I want to read and write excel file . it can do with oledb , there is a limitation maximunm characters < 255 solution is mono data type , now create table become second sheet (when open excel it is shown as hidden.)
I have several cases in my database and for each case there is binary data. I am reading binary data for each case in a byte attray and saving it as a pdf file.I can succesfully open this pdf file.
I have a table in my database that holds the parent child relationships for a distributor binary tree. I need to be able to return this query into my application and have a recursive method to go through any given tree and traverse through all subtrees of the parent tree in order to calculate commissions. Does anyone have any working examples of binary tree traversal?
Also, I'm not exactly sure how I will pass this tree structure to my application. Would I return it as XML?
I tested my app locally and it works perfect, but as soon I publish it, upload it to server and try it, on a 100% copy of my local database it throw me a truncate message; now via this msg
that throws me the error query or via sql profiler I got this query:
My apps required me to store upload files into SQL binary fields. And then allow users to retrieve the files and either chose an apps to view them or save on disk. These files can be in diff formats, not just one type.
I have been reading about using the Response.ContentType method and Response.AddHeader method. The issue is the users can upload anykind of documents, ie: MS words, Xcel, JPEG,TIFF.... So at the time of downloading, I have no way of knowing that type it is to put in the Response.ContentType.
Can't I just stream it to the browser, let the download dialog box handle the type selection? as in when you download a file, the dialog box would ask if you want to select an app to open the file or save it on disk. How would I do so ?
Is there a way to do this in either scalar function form or in an aggregate function form? The problem I'm dealing with is building a security system with multiple tiers of inheritable permissions. Like you'll inherit certain permissions form the department level and then certain permissions from the supervisor level. I'd like to find a way to produce these resultsFor user permissions I pull these binary values and get these results, (they are sorted by their tree node depth level in the hierarchy.
Im using the SMMS result pane to copy paste data it workt fine for all data types except varbinary(Max)
When I copy < Binary-data > from one cell to another cell in the same column I get the following Error:
Invalid value for cell ( row5,column7) the changed value in this cell was not recognized as valid .Net Framework Data Type Byte[]
Error Message: You cannot use the result pane to set the field data other than NULL Type a value appropriate for the data or press ESC to cancel the change.
1)How to convert 64base string to binary in asp.net and store into sql server.
2)when i convert 64 base string into binary & try to store it into database then it has taken so much tiime to insert.

I am using Sql server version enterprise edition 9 on win NT.I have an issue with the stored procedure, when I execute the SP I get an error message "String or binary data would be truncated." In general I know that we get this error when the inserted value is greater than the column length, but in this scenario the SP is failing only the for the section 1 insertion. The same SP contains one more section where we are inserting records in to same table from same source table based on some different condition and it works.I wrote a script in which I copied the section from the SP which has the problem and storing the output of it in an temp table and inserting one by one record using cursors in to the destination table and then it works.I tried with the option SET ANSI_WARNINGS OFF and SET ANSI_NULLS ON, but it did not work. I am sure that it is not failing because of the length of the data inserted.Is there are other configuration that i can set??
I tried the code from this article. And I got the same mistake " the parameter is not valid ". Maybe I'm not aware of something, some setting in sql server or webconfig or sth else. Anyone else who has experience from fetching images from database? The parameter is not valid is the error message. db table contains data. What am I doing wrong?

Does it look like I will be stuck with manually compiling the tables of departmentpermissions and supervisorpermissions base on every possible outcome of inherited permissions or is there a way to do this on the fly in an efficient manner?

How would I convert text to binary using c#. If you don't know what I mean, check this page out:
