Database - Specified File Cannot Be Opened
Feb 20, 2010I can't connect to my database now, although yesterday it was perfectly fine. An error message comes up saying "...A database with the same name exists, or specified file cannot be opened, or it is located on UNC share" this has never happened before. Why can't I access my database?
View 2 Replies.net - The Microsoft Jet Database Cannot Open The File '...' It Is Already Opened Exclusively By Another User
Sep 1, 2011I have a WinForms application that I have taken over support for and it was build using Visual Studio 2005 with VB.Net. The application makes use of an Access database. It runs fine when it is installed as a standalone application, but the install cd for the application also allows for a network install and this is where I am currently encountering issues.
To test the network install I created a folder on my server (Windows Server 2003 SP2) and copied the Access database to this folder. I created a share for this folder and gave everyone full permissions to the share. Then on the workstation I installed the application and gave the path to the database as follows:
\myservermysharemydb.mdb
(The install steps here are as per the instructions given on the installation cd)The workstation that I installed it on is Windows 7 Ultimate. When I run the application, I get the error message given in the title when the application tries to read the database file. I have confirmed that I am able to write to the shared folder on the server, so I don't think this is a permissions issue. Also, the database file is not in use at all, so it is definitely not opened exclusively.
UPDATE:I have tested the workstation installation on a computer with a fresh install of Windows XP SP3 and it is able to access the database file without a problem. So it seems that this error that I am getting is somehow specific to Windows 7. Is there maybe a known issue with Oledb drivers on Windows 7? My version of Windows 7, btw is 32 bit.
Read Data Of A SQLite Database File And Chart Data Using Basic Bars, Pies, Lines?

View 1 RepliesCopy Opened Database - Application Gets It's Data From A Mdb-file And The Connection Remains Open As Long A Person Works?
May 14, 2010The fact is I'm making an application, which users can install by using a Setup file...once installed the data in the database can be updated by a centralized server. To do this, they can insert a DVD/CD-ROM and export the necessary data towards it. I need to do it that way, because some of the users who really need this data will be using stand alone computers.The application gets it's data from a mdb-file and the connection remains open as long a person works with the application (maybe not the best way to do, but I know :-) )...when the user uses the application, he can perform an export...this exports the .ini-file and pictures (which works fine), but he also needs to export the mdb behind the application...I already tried connection.close() before and connection.open() after the System.IO.File.Copy...but that doesn't seems to work.
View 2 RepliesAdd An SQL Database File Using VS 2005 Getting Error Message Saying Version Of Database Server Not Supported?
May 18, 2009I recently upgraded the MS SQL Server installed on my personal computer from 2005 Express to 2008 Express. Problem is when I try to add an SQL database file to a project using VS 2005 I get an error message saying that the version of my database server is not supported, I must have SQL Server 2005 Beta 2 or later installed. I didn't do it yet but I'm pretty sure that when I open the other projects that I included a database file to it, I'm going to get the same error.
My question is it possible to have two SQL Servers installed on my machine? If so, is it a good idea to have two DB servers in the same machine?

Open File Retain The Directory Of The Last Opened File?
Jan 10, 2010So I open files and do whatever with them right. I've set the initial directory to equal the last directory, but whenever I open multiple files, it never sets the directories properly. It acts as though nothing was opened there, so it takes the previous directory as the last one. Thoughts on what's not working? Here's the code.
Code:
With FileOpenDialog1
.InitialDirectory = LastDirectory
If .ShowDialog = DialogResult.OK Then
[code]....
I have multiselect enabled earlier and everything else works but this. When you open a single file, the last directory works fine. It only happens with multiselect.On another note, does anyone know why it freezes when I try to do a lot of files and use another program? I opened 700+ files to see what would happen. When I switched to a IM convo, it froze. When I left it to run, it worked.
Setup File - Developed A Software Using SQL Compact Edition Database (.sdf File)
Nov 15, 2011I've developed a software using VB.Net and SQL compact edition database. (.sdf file) Now i want to add my .sdf file to setup file. I've search internet and create setup file. when i install the software, it is created new folders in program files including my database file and exe file. after double clicking exe file, it is open the software. but when using, it's shown a message "connection current state is closed". but when i run my vb project, it is working well.
Other details.
1) I create data base inside of /bin/debug
2) I've created setup file using this method. File menu --> add --> new project Then, Setup and deployment -> Visual studio installer After that I selected Setup project, then click OK.
3) I add database using this Right click on setup file -> add -> file (In solution explorer window) Then i selected my .sdf file.
This is my connection string
CODE:
It is created only 3 files in Program files.
1. my exe

Sql Filestream - Update A File And Save Changed File Back To Database
Oct 30, 2009I have implemented the filestream feature of SQL Server 2008 in a VB.Net application. I can insert files, and then retrieve/view them just fine. However, I have huge problems trying to update a file. Eg. The user selects a file from the grid which I execute via process.start. If that file is a .txt file, the user may choose to edit it. In case that happens, I need to save the changed file back to the database. So far I have failed to do that.
What I do, is take the retrieved file, copy it (cause i got some errors about it being used), and then Process.Start it. After that, via .NET filestream, I convert the file to bytes and try to update the record. SQL Profiler and a manual SELECT on the varbinary(max) column tell me that the file is updated properly, but the very next try to retrieve it I get an unchanged file.
After that I also tried to update the file by changing its File-System Version, but the file still wouldn't seem to update. Does Anyone have a code sample of how I can achieve this operation? Like 500 sites on the internet have examples of how to Insert And Retrieve the file, but not a single example on how to update. This is how my second attempt of trying to update the file via the filesystem looks like. The code for inserting/retrieving is very similar and it works properly. [Code]

No Access To An Mdb Database File After Copying The File?
May 21, 2009I have the following code where I make an copy of my database that I use. the code executes 100% but the problem I have is I'm not able to access my database afterward.I get a "Cannot start your application. The workgroup information file is missing or opened exclusively by another user." and so if I restart the application it all works fine again.I'm certain the reason is because I can only access that database using a specific account name and password which is not account I'm logged in with.What i want to try is to default that database mdb to the point where no user is accessing it, or to reassign the the only account name that can access it to that database mdb. I've tried playing around with file security but had no luck.

View 6 Replies.net - Several Visual Studio Projects Are Complaining That A Temp File Is Missing And Therefore Cannot Be Opened. Error Code &H80070003
May 31, 2011I'm running Visual Studio 2010 on a terminal server, and have been, with relatively few problems, for some time. This morning I fired up my PC and over the UK's long weekend, the following issue seems to have developed.I've got a bunch of projects (but not all of my projects, and not all of the projects in a given solution) complaining that a particular file (which does not exist on the computer) cannot be opened, and so those projects will not compile anymore. Here's the error:
Error 31 Unable to open module file'C:Users[username]AppDataLocalTemp2.NETFramework,Version=v4.0.AssemblyAttributes.vb':
System Error &H80070003&
I could simply copy the file into that directory and be done with it, I'm pretty sure that will work,EDIT: Okay, now things have gotten to a whole new level of weird. I've rebooted the server, I get the same error message, only now the file it is asking for exists and can be opened in Visual Studio with no problems. another part of the IDE still insists that it's unable to open the module file.
EDIT 2: Can't delete the file because it claims to be open in another program, but I've logged off and logged on again, and there shouldn't be anything accessing it.
EDIT 3: Because there's a wall of comments below his answer, I'll mention here that Jared's suggestion to delete the SUO file for the solutions having the problem (not files specifically to do with any of the problem projects, strangely) was what solved this, eventually.

Firebird Database - Combined All That Data Into One Database File Called RECDATA
Jun 22, 2010I am sitting with a situation that I have to combined (3 years) for 26 site of 29000 database files where there is 1 table in each data base called RECDATA, I need to combined all that data Into one database file called RECDATA.
For example there is a database called DB1 with a REDATA table inside it, and then DB2 with a RECDATA table inside it, DB3 with a RECDATA table inside it est. So I need to put all the Recdata into 1 Database file, or to copy all the RECDATA from all the database files to 1 RECDATA they all have the same columns All I need is to get all that data into 1 RECDATA table.
The program where this database comes from is a voicerecording system creating a new database every day. There is 1 database just for indexing (to view the recordings) and then the daily database is where the recording lies in, that Colum is called RECFILE. I will give you a example of the 2 database.

Nov 10, 2011i am trying to decrypt a file that was encrypted with Des. However not all of the file is encrypted just a few lines are. Here is an example of the file im trying to decrypt:
Random text
Encrypted Text
MD5 Hash
Encryption Key(Only there for tests)
Number of encrypted lines
The idea is to read the last three lines into variables and use them to decrypt the text. At the moment i use the number of lines - (the number of encrypted lines + 3) to find where the encrypted text starts. Then i was trying to copy the encrypted text to a temp file so i could run the code bellow on it, however i am getting an encoding error apparently i need to be using base64 or something. So my question is can anybody explain to me or show me how i can pull the encrypted text out of the file so that i can use the code bellow on it.
Dim DES As New DESCryptoServiceProvider()
'A 64-bit key and an IV are required for this provider.
'Set the secret key for the DES algorithm.
