I have a small vb.net application using window forms with dataset. Currently the database is stored in c:\. When I created the MSI package and installed on another workstation, I need to change the database location to a network drive z:\, but my connection string in app config is already indicated C:\ hence resulted in error.
How can I solve this?

Every application I use to initiate an ODBC connection that I've created to my IBM Notes 9 DB results in getting an error during connect:
Driver's SQLAllocHandle on SQL_HANDLE_DBC failed
I have scoured the web trying to correct this and have not been able to find an answer that solves for this issue on my machine. I am able to open and access the Lotus Notes DB within the Notes 9 software. I am able to create the ODBC System DSN and I know that it's connecting to the server properly because all of the available .nsf files populate in the "Database:" dropdown menu when going through the new ODBC connection setup. I am able to see my username which gets populated from my Notes ID file. The issue occurs when I use something to initiate the ODBC connection. I have tried Excel, QlikView, AQT, Teradata SQL Assistant all with the same result. Once I choose the ODBC connection that I've created, and click on "Ok" in each application I've attempted this with, I am met with the same error above.
I used Event Viewer per a suggestion in an older post online and received the message below:
Could not load NSQLE32.EXE. This file must exist in the same directory NSQL32.DLL and NSQLV32.DLL is in. It is possible NSQLE32.EXE could not be loaded because NotesSQL couldn't locate a valid Notes/Domino installation (couldn't find NNOTES.DLL) -- this may be because user (MYUSERID) does not have the correct rights to the Notes/Domino directory. It could also be because NotesSQL can not find your Notes/Domino installation in the Registry. NotesSQL looks for the NNOTES.DLL file by looking in the path pointed to by the following Registry entries -- HKEY_LOCAL_MACHINE\Software\Lotus\Notes{version}\Path : HKEY_LOCAL_MACHINE\Software\Lotus\Domino{version}\Path. If neither of these registry entries exist or they point to an invalid version of Notes/Domino NotesSQL will not work. To resolve -- please re-install Notes/Domino.
Some notes (no pun intended) and things I've done:
Verified that the DLLs mentioned in Event Viewer do exist in the proper directories.
Run the Nsql_ALM.exe application to configure the NotesSQL driver.
Used the 32-bit ODBC Administrator because my Notes 9 is 32 bit, as well as the driver. The 64 bit driver would not even allow installation (attempted this after hitting this roadblock) but the 32 bit installed successfully.
Modified my System Environment Variable for Path to include the true location to notes.ini, which resides in:
C:\Users\MYUSERID\AppData\Local\Lotus\Notes\Data
Modified my System Environment Variable for Path to include the location to the NotesSQL driver, which resides in:
C:\NotesSQL
Modified my registry to ensure that the appropriate strings exist to reference the proper files:
HKEY_CURRENT_USER\Software\Lotus\Notes\NotesIniPath (to notes.ini)
HKEY_LOCAL_MACHINE\SOFTWARE\Lotus\Notes\9.0\Path (to notes application)
HKEY_LOCAL_MACHINE\SOFTWARE\Lotus\Notes\9.0\DataPath (to notes.ini)
HKEY_LOCAL_MACHINE\SOFTWARE\Lotus\Domino\9.0\Path (to notes application)
HKEY_LOCAL_MACHINE\SOFTWARE\Lotus\Domino\9.0\DataPath (to notes.ini)
Set the NSQLE32.exe application to run in compatibility mode with all other options.
Attempted with everything run as administrator.
Uninstalled both Notes and NotesSQL and reinstalled everything cleanly again.
Attempted a log via Tracing within ODBC Administrator and it will not create a log file when I am attempting the connection. It will populate, however, with all of the system ODBC connections when the calling application attempts a lookup of the existing connections to populate in the dropdown menu. If I start tracing after the dropdown menu has been populated, then attempted the ODBC connection, even multiple times and with multiple versions, a new log file is never created.
I'm not sure where to go from here. Has anybody had this issue and is there something else that I can do in order to fix it?
I was able to correct the issue based on information in the Event Logs (Windows - Application) indicating that the Notes.INI file could not be located. I first added the location of notes.ini to the user and system environment variables, however, the issue persisted. I then moved notes.ini to the c:\NotesSQL folder where database connectivity dll's such as NSQL32.dll are found. This corrected the issue.
The application calling notes is SAP BusinessObjects Edge (Enterprise - Crystal Reports) 4.2 SP07.
notes.ini can not be found - Windows application event log
My company had a very old one form module developed in VB and back end is Access and I was forced to remove that system and re install this application to new system
I had succeed in doing the same and Data entry etc is working fine the only issue is when I am trying to give the print a crystal report form is opening which gives the below message.
I installed Microsoft Access and the db file is also in the directory folder.Can any one sugest any solution please
I've made VB.NET application in VS2010 that uses a 2007 Access database, called MenuDB.mdb. During development, everything was fine.
Now that I'm publishing it, I'm getting weird errors because for some reason the app isn't connecting to the database.
I install the application and run it but as soon as it opens it gives this error:
System.Data.OleDb.OleDbException (0x80004005): Could not find file
'C:\Users\Administrator\AppData\Local\Apps\2.0\Data\OV86PXJA.K3R\8575R5AY.95Z\menu..tion_0d4fa454d69e8e6b_0001.0000_8340d263807cbb71\Data\MenuDB.accdb'.
I know the problem has to do with the way I'm relating the application to the database, but I don't know which way is right. In Solution Explorer I changed the Build Type of MenuDB.accdb to "Content" (earlier it was embedded resource". But it doesn't work either way. In my App.config I have the following connection string:
connectionString="Provider=Microsoft.ACE.OLEDB.12.0;Data Source=|DataDirectory|\MenuDB.accdb"
I want that when I deploy the application, the database should just sit in the application folder, wherever it gets installed. How can I do that?
Edit
I don't mind deploying it in such a way that I need to paste the database somewhere myself on the target machine - as long as it works.
If you have multiple users using the same or similar database, and dont have access to a SQL server (MySQL, MSSQL, or others), then co-locate the database at a central location (preferably network location) that all the users will have access to and change the connection string to accomidate the database location being on the network.
Just let it be known, Access can handle up to 10users when doing simple data retrieval/submission but if you ever have it open while others are accessing via data objects, then you may lock them out.
im working on a Window server 2008, in this server i developed a vb.net 2008 console application that open a excel 2003 file and use its contents to create a xml file, so i have two situations:
1. Differences in execution of the program: if i run the application from the Visual Studio or directly from the executable it open and process the excel without problems but if i configured a task on the windows task scheduler or in the adtempus that execute this program its failed and throws this exception:
Exception from HRESULT: 0x800A03EC- at Microsoft.Office.Interop.Excel.Workbooks.Open(String Filename, Object UpdateLinks, Object ReadOnly, Object Format, Object Password, Object WriteResPassword, Object IgnoreReadOnlyRecommended, Object Origin, Object Delimiter, Object Editable, Object Notify, Object Converter, Object AddToMru, Object Local, Object CorruptLoad)
at .Module1.convertExcelToXmlFile(String excelFile)
i have read alot about this exception, but at the moment im unable to resolved, so I want to know how this program can execute correctly from Visual Studio or directly from the execute but failed when its execute on a task if both situations are in the same server? is there a way to fix this behavior?
2. In the console application when i open the excel file with the open method, the file in excel appears for a few seconds then it closed, is there a way to access the excel file contents but that the file dont show in Ms Excel?
thanks.
You should not be using Office Interop in an unattended process.
Microsoft does not currently recommend, and does not support, Automation of Microsoft Office applications from any unattended, non-interactive client application or component (including ASP, ASP.NET, DCOM, and NT Services), because Office may exhibit unstable behavior and/or deadlock when Office is run in this environment.
If you are building a solution that runs in a server-side context, you should try to use components that have been made safe for unattended execution. Or, you should try to find alternatives that allow at least part of the code to run client-side. If you use an Office application from a server-side solution, the application will lack many of the necessary capabilities to run successfully. Additionally, you will be taking risks with the stability of your overall solution.

There are a number of products that will manipulate Excel docs and run correctly unattended.
Is the Excel file you're trying to open on the network?
If so, the problem is most likely because your Task Scheduler service and any jobs it runs are (by default) running under the local SYSTEM account, which is prohibited from network access.
If you change the task to run under a different account (say, for example, a domain account that you have given privileges for the remote fileshare). (Note that this change may effect how other scheduled tasks run, so you'll want to be quite sure of the permissions needed.)

If your server is a 64-bit one, create a folder named 'Desktop' in the below mentioned path i.e. C:\Windows\SysWOW64\config\systemprofile\Desktop
If your server is a 32-bit one, please make this folder C:\Windows\System32\config\systemprofile\Desktop
Mainly looking to answer my question #1 below, but more knowledge would be appreciated.
I tried to use these resources during my investigation, but was unsuccessful:

Questions
1.) Why does this error occur while running the Telerik Rad Controls for ASP.NET AJAX "Live Demos" project with IIS 7 (Running Telerik Live Demos works fine using ASP.NET Development Server with this connection string)
Failed to generate a user instance of SQL Server due to failure in retrieving the user's local application data path. Please make sure the user has a local user profile on the computer. The connection will be closed.
2.) How is creating a SQL Server Express instances different in IIS 7, from ASP.NET Development Server & SSMSE
3.) Are there certain attributes of a SQL connection string not allowed when running a website on different contexts (based on #2).
Environment:
I'm not running the "Live Demos" .NET 3.5 ASP.NET web application via the ASP.NET Development Server (feature that pops up in your system tray and picks a port for you after clicking play in Visual Studio). That works just fine! I'm running the website on IIS 7. SQL Server Express is using the NETWORK SERVICE user in Control Panel > Administrative Tools > Services > SQL Server (SQLExpress).
Using this connection string provided with the installed "Live Demos" web application demo project:
<add name="NorthwindConnectionString"
connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|Northwind.mdf;Integrated Security=True;User Instance=True"
providerName="System.Data.SqlClient" />
I've tried setting "User Instance=False", but that just throws another error:
CREATE DATABASE permission denied in database master. An attempt to attach an auto-named database for file ? failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.
(where "?" is the path of the *.mdf file - C:\Users\\MyDocuments\Visual Studio 2008\Projects\TelerikDemos\Telerik\RadControls for ASP.NET AJAX Q2 2011\Live Demos\App_Data\Northwind.mdf .. Stack Overflow italics is broken with some of those characters, so I had to remove that path)
Someone answered me on a previous question to set this "User Instance=False", but it appears User instances have nothing to do with whether or not you use SQL Express. User Instances are simply a feature of SQL Express that allows a very unprivileged user to host a database instance in it's own user context.
Note, this Northwind database is stored in an *.mdf file in the App_Data folder (under the "Live Demos" root application directory) along with the *.ldf (log file). I did previously try attaching the *.mdf files as actual databases under the "Databases" folder (in the SSMSE Object Explorer tree), but later removed them.
Web application "Live Demos" root folder (and nested folders/files) have the following users assigned with ALL privileges:
- IIS APPPOOL\Telerik ("Telerik" is the name of my application pool in IIS 7 for this site)
- IUSR
- NETWORK SERVICE
Making a note for myself about this SQLExpress master database query:
SELECT * FROM sys.dm_os_child_instances
Also tried different combinations of *.mdf & *.ldf permissions while also changing the user on the SQL Server (SQLExpress) Windows 7 service (Control Panel > Administrative Tools > Services) .. and also restarted the service after making those changes.
To reproduce:
download the Telerik Rad Controls for ASP.NET AJAX. Set the permimssions I mentioned in the "Live Demos" folder under Program Files\Telerik, change the .NET version of the web application to .NET 3.5, switch out their 3.5 web.config file with the normal web.config file in that folder. You have to use Visual Studio 2010, but I am running this in Visual Studio 2008 (with a little grunt work I did because our company is not yet on VS2010). Also switch out the proper Bin35 assemblies into the "Live Demos" folder Bin folder. Compile the solution. Create an IIS 7 website. Add Windows authentication. Enabled anonymous and Windows authentication.. all others are disabled. Set application pool to use Classic and 32 bit.
Then navigating to this URL and clicking the "First Look" image.

====================
More evidence will be provided if requested.
You are using a connection string with trusted authentication = true. This means that the connection uses the security context of the calling process.
When you run with the development server you are running in the security context of the logged in user, so every thing works fine.
When you run in IIS you are in the security context of the application pool process, which is NETWORK SERVICE, which does not have a user profile, therefore it crashes.
You can fix it by either:
Change the identity of the application pool to a normal user with access to the database
Use a connection string with user name and password
IIS doesn't load the Windows user profile, but certain applications might take advantage of it anyway to store temporary data. SQL Express is an example of an application that does this. However, a user profile has to be created to store temporary data in either the profile directory or in the registry hive. The user profile for the Network Service account was created by the system and was always available. However, with the switch to unique Application Pool identities, no user profile is created by the system. Only the standard application pools (DefaultAppPool and Classic .NET AppPool) have user profiles on disk. No user profile is created if the Administrator creates a new application pool.
However, if you want, you can configure IIS application pools to load the user profile by setting the LoadUserProfile attribute to "true".
