I'have created windows phone 8 application 6 months back. In that application I have used the SQLite database. For this I've followed the below link.
http://social.technet.microsoft.com/wiki/contents/articles/18204.how-to-use-sqlite-with-a-windows-phone-8-application.aspx
Everything was fine. I have successfully stored and retrieved the data in the SQLite databse.
Now suddenly the SQLite reference which I used is not working. To solve this I have removed the reference of SQLite from the project. I followed the same procedure which is mentioned in the above link. Now my solution contains 2 projects, one is Sqlite (which is c++ wrapper) and another one is SqliteDemo (Windows Phone Application).Everything is fine up to this. But when I try to build the application, then it is saying that All the projects with in the application must target the same platform.Use configuration manager to change the values.
I change the project platform to ARM and try to build the file. But the same error it is throwing.I change the project platform to X86 and try to build the file. But the same error it is showing. For reference please see the below image.
Please help me how to solve the issue.
Thanks

I am running WatermelonDB (which uses SQLite) on React Native. I am using the iOS simulator, and I am trying to locate the database file so I can query on it directly. It seems that I am able to successfully save to the database, since I can query data from within the app and it gets persisted.
Using htop, I have been able to find the running process of my application running on the simulator. However, when I cd into that directory, I see no .db file. I can even go to the root of all simulators ~/Library/Developer/CoreSimulator/Devices/ and ack for all db files, and still nothing shows up.
Next, I have tried launching the app in Xcode, as I have come across other posts that suggest checking the logs of Xcode, which is supposed to reveal the db location. Alas, this has shown me no information.
I am first interested to know how it is possible that anything at all is getting persisted, given that I cannot find a db file.
Second, should I be building my app from Xcode, or is it fine to use command line react-native run-ios? I can see that running this command uses Xcode under the hood, but I'm not sure if there are benefits to using Xcode. Nonetheless, using Xcode does not provide me with the answer I am looking for.
note: this is not a duplicate of this nor this, as I have followed all suggestions but have been unable to reach the conclusion
You can locate the watermelon.db files on your machine created by the iOS simulator by:
cd /Users/<your username>/Library/Developer/CoreSimulator/Devices
find . -name "watermelon.db"
This will show you the instances of watermelon.db files created by simulators. You can then take the output to an SQLite inspector and open /Users/<your username>/Library/Developer/CoreSimulator/Devices + {file path from find}.
If you have multiple results, then you may need to deduce which simulator is which by matching the ID to the simulator using xcrun instruments -s devices
I cannot get VS 2015 to create my EDMX file for an Oracle Connection.
I am using Visual Studio 2015 Update 3
I have installed the Oracle Developer Tools 12.1.0.2.4
I have installed Oracle Data Access and the following DLLs exist under \ client[user]\product\12.1.0\client\odp.net\bin
2.x\Oracle.DataAccess.dll version: 2.121.2.0 ODAC Release 4
4\Oracle.DataAccess.dll version: 4.121.2.0 ODAC Release 4
I am using the following assemblies
Oracle.ManagedDataAccess Version: 4.122.1.0
Oracle.ManagedDataAccess.EntityFramework Version: 6.122.1.0
* I believe both of these are version 12.2.1100 based on the folders in which they reside in the packages folder.
There are no connections defined in the Server Explorer
My steps are as follows:
Within the Solutions Explorer, Right click on project and select "Add" | "New Item..."
Select Data | ADO.NET Entity Data Model | Add
Select EF Designer from Database | Press Next
In the Entity Data Model Wizard:
Press New Connection... (I get an warning "Failed to find the default tnsnames.ora file." I ignore and press "OK"
With the Datasource as "Oracle Database (ODP.NET, Managed Driver)" I enter the credentials and specify the the other
connection parameters and press "Test Connection" which SUCCEEDS.
I press OK and am taken to the next page in the Entity Data Model Wizard
I include sensitive data in connection string and Press Next....
WIZARD SHUTS DOWN (crashes) - NO EDMX CREATED
Any assistance in helping me troubleshoot this would be greatly appreciated.
TIA - Xavier
Thanks to #Hong-vit pointing me in the right direction. I found the answer.
When you visit the download page for ODAC you're given a selection of version numbers.
In my case the top two were:
ODAC 12.2c Release 1 and Oracle Developer Tools for Visual Studio (12.2.0.1.0)
ODAC 12c Release 4 and Oracle Developer Tools for Visual Studio (12.1.0.2.4)
For me the top one wouldn't install. It would cut out during the installation process (thanks Oracle!) so I settled with the second one (12.1.0.2.4).
This meant that when I installed Oracle.ManagedDataAccess and Oracle.ManagedDataAccess.EntityFramework I had to select the correct version.
Not for me:
The one I needed
As you can see the version numbers (almost!) match up:
ODAC 12.2.0.1.0 = Oracle.ManagedDataAccess 12.2.1100
ODAC 12.1.0.2.4 = Oracle.ManagedDataAccess 12.1.24160719 (yay!)
I believe this is a failing on oracles behalf as it's not made clear despite their inclusion on a page long readme on which this doesn't feature. In additon the version numbers not quite being the same...but that's a rant for the blog.
I have the same bug. I fixed it successfully by follow this step:
On your project Right click -> Select Manage NuGet packages on Browse tab input oracle. You will see Oracle.ManagedDataAccess.EntityFramework. Select version of oracle you have installed. This should be 12.1.2400. Install it, you are done
I had the same issue - I hope I can help fellow Googlers having the unfortunate task of connecting Oracle and Visual Studio.
I followed the steps and still got crashes - because I was using VS2017 (I understand that the questions is tagged VS2015). You'll need to install the VS2017 ODAC Client. Thankfully, this one actually does something when you begin the installation. The installer in the link on the accepted answer will only work for VS2015.
The most recent version (as of this time of writing) of ODP.NET is 18.3, which can be installed through NuGet (Oracle.ManagedDataAccess.EntityFramework). Follow these steps on Oracle's website and you'll be setup.
...Or so you think. I got the same error as in this stack overflow question, where it won't go past the Entity Data Model Wizard.
I applied every configuration in the selected answer, but it still wouldn't work. When I downgraded my Oracle.ManagedDataAccess.EntityFramework from 18.3.0 to 12.2.1100, I could finally create my models!
I have had the same problem when I was trying to connect Oracle Entity Framework with Visual Studio 2017.
After install and unistall several times differents version. The build that better works for me is:
Oracle Developer Tools for Visual Studio 2017 (ODTv2017) v12.2.1200
Oracle.ManagedDataAccess v12.2.1100
Oracle.ManagedDataAccess.EntityFramework v12.2.20190115
EntityFramework .NET v6.3.0
I think that having similar versions in Oracle packages is very important for good performance.
It looks like someone here had similar issue: He add to change implementation somehow.
[in this ]case a View (valid and worked) caused the crashes. After changing the implementation without using that view it worked (more or less).
What I advise is you proceed step by step, only importing one object for the first time you test the wizard, then only simple table, then add procedures, views...
I'm working with SQLite and Windows 10.
I followed this video SQLite Local Database (28th minute) to find the package and .sqlite file. But when I entered AppData/Local/Packages, I didn't find any package has the same name as my project's package's name.
Can anyone help me find the package folder of windows 10 app project? Thank a lot!
Try following steps:
WIN menu -> all apps -> right click on your app (App1 in your case) -> click uninstall. This will clear the previous app data.
In Visual Studio, right click on the project node -> Deploy.
Try to find and run your app from the app list to make sure it deployed correctly. then check if you can find the folder. This time you can easily find the folder by sorting on modified date.
If it still doesn't work, see if you can repro the issue with a new blank project.
[Update]
If the app locates on phone or phone emulator, Use Windows Phone Power Tools (works for windows 10) to browse folders. Here is a screenshot for your reference:
I don't trust the native Sqlite3 in MonoTouch anymore. I keep getting random crashes and although I cannot prove it, I claim that it is not my fault.
To verify this I would like to use a managed replacement of Sqlite3.
Is there a project that is syntax compatible with the native version? And more important: does somebody have experience with it?
Look at the Xamarin cross-platform MWC sample.
While it use the native libsqlite on iOS and Android versions it does use a fully managed port of SQLite for the Windows phone version (where SQLite is not available and where it's not possible to add native code).
However that won't tell you what's wrong with your application. If you're using other native libraries in your project I suggest you to remove them (one by one) and try to duplicate the sqlite crash again.
Hoping that I do this corectly.
I am having the above issue. My development machine is win7 64. Im developing x86 application,(x86 set in compile options). I have downloaded sqlite-netFx40-setup-bundle-x86-2010-1.0.81.0 as my app will be on .net4. I have referenced the above dll, set it to copy local. Can confirm that its in the deployed dirrectory. Tests OK on development machine both as a debug and a fully instaled app. When I put the app on a separate win 7 64bit it wount run due to the Dll. It installs ok into ProgramFiles(x86) and runs untill the database is required. The dll is in the instaled dirrectory when instaled on the other PC. (fresh win instal).
I am using InstalShield and it is also telling me about an error ' -6248: Could not find dependent file system.data.sqlite.dll, or one of its dependencies of component' but it compiles OK.
Im stearing at the Dll in the program , in the references, the intelisence picksup the SQLite name and all the code is right. I have referenced by browse and then finding the dll.
What on earth could I be doing wrong ?
This has had so many views that I decided to answer this so as to help others.
The problem isnt a big deal once you know what it is, despite the error message that sends you almost in the wrong dirrection. The problem isnt the DLL, its one of its dependancies. Basicaly you have to install C++ distributable file on the client machine , even if you are using VB.net. I cant take credit for the find, it comes from here http://justanothersoftwareengineer.blogspot.com.au/2011/08/how-to-make-systemdatasqlitedll-work-on.html.
