Accessing Documents From SQL Server Database?
Feb 15, 2009
I have saved documents into my SQL Server 2005 database and they have been converted to bytes. My web page is made with VB.NET in Visual Studio 2008 with ASP.NET. The following is exactly what I need to achieve;
1. Allow user select document with a button
2. Select the document from the SQL Server table
3. Allow the user to download this document.
The error I am getting is that Category is set as Byte and it can't be passed through GetDocument because filePath is a String. I think that I am pulling the file path from the database wrong
[Dim Category As Byte() = NothingDim fs As FileStreamDim br As BinaryReaderDim document As Byte()Dim documentFilePath As String
Protected Sub ImageButton1_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles ImageButton1.Click
myConnection = New SqlConnection("server=ORLA-PCSQLEXPRESS;database=Edpac;

I want to write a program using vb.net tht compares the name of a document on my desktop to the name of the document on the server. If they're the same then I'd like to retrieve it and have it replace the file I already have.How can i do this? Does this mean that i have to write a web application cuz i hope not. I dont no anything about those. I am using that server for storage purposes only so i assumed that i didnt need a database for the name of the document.

So, how can i do this? Is there an existing class/package in vb.net that does something like this?

I have this database with a table which has the the following but I have no way to decypher it
DATA, TYPE, FILE TYPE, SIZE, DOC TYPE
0x15234324 , Word.Document.8 ,DOC, 19968, WORD.DOCUMENT.8
The field seems to contain a word document stored in a SQL Server IMAGE column
Has anyone come across this before or a way to extract this data in a readable format?
So far I have tried using PHP to extract the file and write it to a word document but not had much luck.
UPDATE: I now have Visual Studio Express and would like a way to extract this data and save to a word document
UPDATE2: This is what I have in VB sofar

In our VB.Net application, we need to get the path to our data folder in Public Documents. In our standalone application this is straighforward using the SHGetFolderPath function. However, for our network application, we run into a problem when we load the application on a Win 7 server and run it from a Win XP workstation. From the workstations, SHGetFolderPath returns the workstation's public documents folder instead of the what we want, which is the server's public documents path.Is there any way within the application to query the public documents path on the server?

I am not an expert programmer and am just getting familiar with .NET office automation. I have two questions:
1. For me to create word documents from my code on a server, does word have to be installed on the server? My test server does not have word installed. Is there a way to have the code open word on the user's machine in this case?
2. I am trying out some code for creating word documents. It works fine on my machine. However, when I try to run it on server it gives me an error.. "Cannot create ActiveX component." Is this a permissions issue or related to the fact that the server does not have word installed?

I have a Search web reference (from a Search Server 2010 express install) in a vb.net application that is utilizing the QueryService Class to search a production Sharepoint foundation 2010 site.At a previous point in time, we had created a proof of concept on an entirely test system that has since been turfed. From my recollection on this test system when documents were uploaded as a specific site content type (that inherits from document) and metadata was provided, we could search for specific metadata by making managed properties for each, and search results would be returned as documents (with the isdocument flag set to true). Viewing the document then became simple, as we could simply use the filename and path to display the stored file.Now we are developing a production system and we have encountered a new behavior, where these results now are returned as aspx results such as
[URL]
This of course makes it terribly difficult to locate and view the document, we can extract the Title which will then give us the name of the file with no extension, but that hardly helps, as the FileExtension data is aspx, not the documents file extension, so we don't have a full filename. We could display the page returned as a result, but would much prefer the document itself.
I've made a test document library, with just bare bones setup, (not using the site content type, or site columns) and uploaded some documents on the same site, and they are returned in the same fashion, so I don't believe the document library, or content type are the issue.
With a fairly limited understanding of both Sharepoint and Search Server, I don't know if this is a setup issue with the search service itself, with the site configuration, or with the querypacket I am sending. We also have a third party application (Knowledgelake) installed on the server that ties into sharepoint which could have changed configuration somewhere as well?
I don't think the query packet has changed since it was working in the proof of concept, other than the custom data column names. I will provide it here in case there is something glaringly obvious to an external reader.
<QueryPacket xmlns='urn:Microsoft.Search.Query.Document'>"
<Query>
<SupportedFormats>
<Format>urn:Microsoft.Search.Response</Format>

I've been asked to get the page counts for documents stored as tif files. What I have now is looping through our third party software to open them and then get the page count. I can't stop the image from flashing and it is very slow. Does anyone know of a way to loop through them quickly and can the page counts (one image can have many documents)?

I am creating a program for my company. My goal is to create a database that manages all the documents that we have and the training progress of all the employees as well as to do some Computer Based Assessments that prints the results etc. I have watched allot of the videos posted on this website but was hoping that someone could help me with videos that explain how to play a sound when a button is pressed - How to open up a pdf form from a button or label - How to open a existing OFFICE documents like word and excel. this would help me allot - Also advice in doing a report that can be printed from the answers on the test.

I have a requirement for a form where user can add a list of 'documents'. These could be word, excel, images etc... pretty much anything. They want a form where they use the openfiledialog to locate the document and then want the list of documents stored on a database.
However, when they view this form they want a preview of all of the listed documents and the ability to print them all. I was considering a datagrid view with image cells but how would I show a word document in there? Or, should I insist that they convert all documents to PDF's?

How would I access a specific record and put it into a variable to compare against user input?I have a table CASHIERS and part of that table is a BadgeID and a PIN number. What I want to do is when a cashier swipes there badge to logon to a POS.. it searches the DB to see if the cashier exists. Then, once it establishes that they do exist, it pulls their PIN # and prompts them to enter it. It compares the data retrieved from the DB to the data that they entered.

I am currently working on a project for school. I have the project all laid out in my mind and everything but there is one thing that stops me. I can not access the data from the database itself ...
(detailed info)
I am using an AMD Athlon x64 bit processor with a windows vista 64 bit operating system. I am writing the program on visual basic 2008 express edition. When I open up the visual basic 2008 express edition and create a new project the first thing I do is go to the view menu and activate my database explorer. I connect to the database in question through the database explorer. The database I am connecting to is an access 2007 database (ive opened up the access 2007 files and they do open and display information properly, in otherwords, they do work) I then put in a listbox and use the following lines of code in a form load event to both A) create the datatable and B) automatically fill the listbox with the database info.
Dim dt As New DataTable()
Dim connStr As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=MEGACITIES.MDB"
[Code]....
When I test the program the listbox does not fill up with any information from the MEGACITIES access 2007 database. Ive tried connecting to the database by establishing a connection through the datasources window. Ive tried establishing a connection to the database through both the database explorer and data sources window. No matter what I try I can not get that information accessed.
Im almost confident that this has to do with my processor being 64 bit.

I have a table called Cashiers. In that table are three columns: the primary key, badge and pin.
The user inputs the badge number into, let's say, textbox1.
I want to locate that row and store the corresponding pin number into a variable called pinVar.
This way I can compare it to the input received when it's time for them to enter their pin.

I want to create and populate populste several databases on my server MySQL. I pretty much know how to handle the data and queries once I have a connection, it is connecting that I don't know how to do. I have read all the help file I can find till I am sick of reading about "Northwind" which doesn't help me a t all. What I need are the three or four lines that establish a connection to MySQL at [URL] I need to be able to establish this connection transparent to the user who needs only to put thier user name and password for the site into a configuration file. Then I need to be able to create a database and give the user access with thier username and password. I know how to create the database but not how to set the username, password and permission.

Is it possible to add, edit, view and delete records using a file only (instead of a database) and .Net 2005 (VB.Net/C#)? The concept is that a file that'll work more-or-less like a database. One can add, edit, view, delete and query data to and from the file. The file, either cannot be opened directly or data inside the file should be in some encrypted form so that even if the file is opened no one can comprehend it. Data inside the file can only be manipulated by a front end application i.e. .Net 2005.
