How do you Get an existing database from a device or emulator ?
device not rooted
I'm using Microsoft.WindowsAzure.MobileServices
public bool InitialiseDb()
{
try
{
Store = new MobileServiceSQLiteStore(offlineDbPath);
Store.DefineTable<Products>();
_client.SyncContext.InitializeAsync(Store);
this.productTable = _client.GetSyncTable<Products>();
return true;
}
catch (Exception ex)
{
Debug.WriteLine(ex.Message);
return false;
}
}
You can copy the existing database into a folder you can access
Create path to database :
string filepath = "data/data/[package-name]/files/[name-of-db]";
You can get your package name from your android project options
then use the following code to extract it:
string filepath = "data/data/com.foo.foo/files/localstorage.db";
var bytes = System.IO.File.ReadAllBytes(filepath);
var fileCopyName = string.Format("/sdcard/Database_{0:dd-MM-yyyy_HH-mm-ss-tt}.db", System.DateTime.Now);
System.IO.File.WriteAllBytes(fileCopyName, bytes);

Your code won't work against an OnPrem Public folder tree as EWS in Office365 won't proxy to an OnPrem Exchange Org (even if hybrid is setup). (Outlook MAPI is a little different and allows this via versa setup but in that case it never proxies either it just makes a different connection to that store and its all the Outlook client doing this).
Because your trying to use the client credentials oauth flow for that to work onPrem you must have setup hybrid modern authentication https://learn.microsoft.com/en-us/microsoft-365/enterprise/hybrid-modern-auth-overview?view=o365-worldwide. Then you need to acquire a token with an audience set to the local OnPrem endpoint. (this is usually just your onPrem ews endpoint's host name but it should be one of the service principal names configured in your hybrid auth setup Get-MsolServicePrincipal). So in your code you would change
var ewsScopes = new string[] { "https://outlook.office365.com/.default" };
to
var ewsScopes = new string[] { "https://OnPrem.whatever.com/.default" };
which will then give you a token with an audience set for the onprem server then you need to send the EWS request to that endpoint so change that eg
ewsClient.Url = new Uri("https://OnPrem.whatever.com/EWS/Exchange.asmx");
if Hybird Modern Auth is setup then you need to default back to use Integrated or Basic Authenticaiton.
I'm using Xamarin.Forms and I am trying to convert an html string to a pdf file using EvoPdfConverter, but the problem is that when I try to do so, on the line htmlToPdfConverter.ConvertHtmlToFile(htmlData, "", myDir.ToString()); in the code snippet below, the app just freezes and does nothing, seems like it wants to connect to the given IP, but it can't, however I don't get any errors or exceptions! not even catch!! does anybody know what I should do to resolve this issue? and here is my code for this:
public void ConvertHtmlToPfd(string htmlData)
{
ServerSocket s = new ServerSocket(0);
HtmlToPdfConverter htmlToPdfConverter = new
HtmlToPdfConverter(GetLocalIPAddress(),(uint)s.LocalPort);
htmlToPdfConverter.TriggeringMode = TriggeringMode.Auto;
htmlToPdfConverter.PdfDocumentOptions.CompressCrossReference = true;
htmlToPdfConverter.PdfDocumentOptions.PdfCompressionLevel = PdfCompressionLevel.Best;
if (ContextCompat.CheckSelfPermission(Android.App.Application.Context, Manifest.Permission.WriteExternalStorage) != Permission.Granted)
{
ActivityCompat.RequestPermissions((Android.App.Activity)Android.App.Application.Context, new String[] { Manifest.Permission.WriteExternalStorage }, 1);
}
if (ContextCompat.CheckSelfPermission(Android.App.Application.Context, Manifest.Permission.ReadExternalStorage) != Permission.Granted)
{
ActivityCompat.RequestPermissions((Android.App.Activity)Android.App.Application.Context, new String[] { Manifest.Permission.ReadExternalStorage }, 1);
}
try
{
// create the HTML to PDF converter object
if (Android.OS.Environment.IsExternalStorageEmulated)
{
root = Android.OS.Environment.ExternalStorageDirectory.ToString();
}
htmlToPdfConverter.LicenseKey = "4W9+bn19bn5ue2B+bn1/YH98YHd3d3c=";
htmlToPdfConverter.PdfDocumentOptions.PdfPageSize = PdfPageSize.A4;
htmlToPdfConverter.PdfDocumentOptions.PdfPageOrientation = PdfPageOrientation.Portrait;
Java.IO.File myDir = new Java.IO.File(root + "/Reports");
try
{
myDir.Mkdir();
}
catch (Exception e)
{
string message = e.Message;
}
Java.IO.File file = new Java.IO.File(myDir, filename);
if (file.Exists()) file.Delete();
htmlToPdfConverter.ConvertHtmlToFile(htmlData, "", myDir.ToString());
}
catch (Exception ex)
{
string message = ex.Message;
}
}
Could you try to set a base URL to ConvertHtmlToFile call as the second parameter? You passed an empty string. That helps to resolve the relative URLs found in HTML to full URLs. The converter might have delays when trying to retrieve content from invalid resources URLs.
I’m using Realm for my Xamarin forms App.I have synced my data in Sql server with Realm cloud.Now I want to view the data which is there in Realm cloud in my Xamarin Forms App.
I used code
public ListsViewModel()
{
LogoutCommand = new Command(Logout);
AddressCommand = new Command(AddList);
//TaskLists = new IQueryable<Address>();
IQueryable<Address> TaskLists = Enumerable.Empty<Address>().AsQueryable();
//AddList();
}
private void AddList()
{
_realm = Realm.GetInstance();
TaskLists = _realm.All<Address>();
TaskLists.Count();
}
My TaskLists.Count() gives 0.But my ROS has the data from sql server and they both are in sync.And I'm able to Login to my Realm Object Server through my Xamarin Forms App.But my Xamarin Forms app is not syncing with my ROS that is the data which is there in my Realm object server is not displaying in my APP.I want to display the data of Address class in my App.The data of address class is put through SQL server.I just Have to retrieve the data of Address class. I even tried using SyncConfiguration.
private async void AddList()
{
User user = null;
try
{
user = User.Current;
}
catch (Exception ex)
{
HandleException(ex);
}
if (user == null)
{
try
{
user = await NavigationService.Prompt<LoginViewModel, User>();
}
catch (Exception ex)
{
HandleException(ex);
}
}
else
{
var uri = user.ServerUri;
Constants.Server.SyncHost = $"{uri.Host}:{uri.Port}";
}
var config = new SyncConfiguration(user, Constants.Server.SyncServerUri)
{
ObjectClasses = new[] { typeof(Address) }
};
_realm = Realm.GetInstance(config);
//_realm = Realm.GetInstance();
TaskLists = _realm.All<Address>();
_realm.Write(() =>
{
_realm.Add(new Address { ID = 8, ZipCode = "Judson123" });
});
TaskLists.Count();
}
Still I’m not able to fix it.Please Help me with this.
I have 2 servers in AD (2008R2)
On one of them I have shared folder (c:\Shared\dirForUserAAA ==> \DC1\dir1)
On other one I have c# program that must manage folder quota on \DC1\dir1
Is it possible and how it can be done?
I try to use this piece of code, but it works only on local paths :(
public static void SetQuotaToFolder(string UNCPathForQuota, int quotaLimitBytes)
{
if (!Directory.Exists(UNCPathForQuota))
{
Directory.CreateDirectory(UNCPathForQuota);
}
// Create our interface
IFsrmQuotaManager FSRMQuotaManager = new FsrmQuotaManagerClass();
IFsrmQuota Quota = null;
try
{
// First we need to see if there is already a quota on the directory.
Quota = FSRMQuotaManager.GetQuota(UNCPathForQuota);
// If there is quota then we just set it to our new size
Quota.QuotaLimit = quotaLimitBytes;
}
catch (COMException e)
{
unchecked
{
if (e.ErrorCode == (int)0x80045301)
{
// There is no quota on this directory so we need to create it.
Quota = FSRMQuotaManager.CreateQuota(UNCPathForQuota);
// And then set our desired quota
Quota.QuotaLimit = quotaLimitBytes;
}
else
{
// some other COM exception occured so we return the error
Console.WriteLine(e);
return;
}
}
}
catch (Exception e)
{
// Generic error handling would go here
Console.WriteLine(e);
return;
}
// and finally we commit our changes.
Quota.Commit();
}
}
Old Question, but if someone needs a hint:
Open a RemotePowershell on the server where your folders are saved. Then use the Cmdlets from here
Some code snippets:
Open Runspace:
public static Runspace CreateAndOpen(string domain, string username, string password, string computername)
{
string userName = username + "#" + domain;
var securePassword = password.ToSecureString();
PSCredential credential = new PSCredential(username, securePassword);
var connectionInfo = new WSManConnectionInfo(false, computername, 5985, "/wsman", shellUri, credential);
connectionInfo.AuthenticationMechanism = AuthenticationMechanism.Default;
connectionInfo.OpenTimeout = 2 * 60 * 1000; // 2 minutes
Runspace powershellRunspace = RunspaceFactory.CreateRunspace(connectionInfo);
powershellRunspace.Open();
return powershellRunspace;
}
Set a quota on a path
public void SetQuotaTemplateOnPath(Runspace runspace, string path, string template)
{
using (var pipe = runspace.CreatePipeline())
{
var newFsrmQuotaCommand = new Command("New-FsrmQuota");
newFsrmQuotaCommand.Parameters.Add("Path", path);
newFsrmQuotaCommand.Parameters.Add("Template", template);
newFsrmQuotaCommand.Parameters.Add("Confirm", false);
pipe.Commands.Add(newFsrmQuotaCommand);
var results = pipe.Invoke();
if (pipe.Error.Count > 0)
{
//Handle error
}
}
}
I m using Opendialogbox to read the file. Then stored the file in byte[] array.
file --> byte []
byte[] --> stored on SQL AZure in varbinary(max) field.
Here is my code:
OpenFileDialog ofd = new OpenFileDialog();
if ((bool)ofd.ShowDialog())
{
FileStream fileStream = ofd.File.OpenRead());
byte[] buffer = new byte[fileStream.Length];
int read = 0;
using (BinaryReader binaryReader = new BinaryReader(fileStream))
{
do
{
read = binaryReader.Read(buffer, 0, Convert.ToInt32(fileStream.Length));
// Stored the File in byte[] Array buffer
} while (read > 0);
}
}
Now I want to convert this byte array to the original file (like .doc,.txt,jpeg). i know the extension in which file is to be convert.
SQL AZure ---> byte[] // done
byte[] ---> to original file. // Problem
Please give solution to download the file.
One way - not necessarily the best - is as follows:
using (MemoryStream ms = new MemoryStream(theBytes))
{
using (FileStream fs = new FileStream(string.Format("C:\\tempfile.{0}", theExtension)))
{
ms.WriteTo(fs);
}
}
namespace FileSaveDialogDemo
{
public partial class MainPage : UserControl
{
#region Fields
SaveFileDialog dialog= new SaveFileDialog();
#endregion
#region Constructors
public MainPage()
{
InitializeComponent();
this.dialog = new SaveFileDialog();
try
{
this.dialog.DefaultExt = ".txt";
this.dialog.Filter = "Text Files|*.txt|Log Files|*.log|All Files|*.*";
this.dialog.FilterIndex = 2;
}
catch ( Exception ex )
{
this.tblError.Text = "Error configuring SaveFileDialog: " + ex.Message;
}
}
#endregion
private void btnSaveFile_Click( object sender, RoutedEventArgs e )
{
bool? dialogResult = this.dialog.ShowDialog();
if ( dialogResult == true )
{
try
{
byte[] fileBytes; // your varbinary file from database
using (Stream fs = (Stream)dialog.OpenFile())
{
fs.Write(fileBytes, 0, fileBytes.Length);
fs.Close();
lblMsg.Content = "File successfully saved!";
}
}
catch ( Exception ex )
{
this.tblError.Text = "Error calling service: " + ex.Message;
}
}
} // End of Function
}// End of MainPage class
}
It seems the issue you have has probably nothing to do with saving a binary file; it is more likely a basic security issue. Try saving to a path on which you have programmatic write access. For example, try saving to your My Documents directory instead of C:. Try using the Environment.SpecialFolder enumeration like this, and append the file name + extension.
Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments)
You have a number of other ways to work around this issue, including starting Visual Studio in Elevated Mode (run as Administrator), and/or allow "Everyone" write access to your C:\ drive. But I wouldn't recommend these techniques necessarily; consider saving to a folder where the security settings are lower than c:\, such as My Documents.
