I am trying to copy a preloaded SQLite db into my UWP app. On the initial installation it copies the "test.db", but the size is 0 bytes and there are no tables or data. The original db is 1300 bytes with data and tables.
Another factoid...when I create the app Using Visual Studio 2017 and compile and run/debug the app it works fine, but when I sideload the appx file or download from the Windows Store the db is empty.
Here is the code that I am using:
Task task = CopyDatabase();
private async Task CopyDatabase()
{
bool isDatabaseExisting = false;
try
{
StorageFile storageFile = await ApplicationData.Current.LocalFolder.GetFileAsync("Express.db");
isDatabaseExisting = true;
}
catch
{
isDatabaseExisting = false;
}
if (!isDatabaseExisting)
{
StorageFile databaseFile = await Package.Current.InstalledLocation.GetFileAsync("Express.db");
await databaseFile.CopyAsync(ApplicationData.Current.LocalFolder, "Express.db", NameCollisionOption.ReplaceExisting);
}
}
I'm not getting any error messages.
Does the your database file deployed correctly to the target system?
To confirm it, see your deployed - "Package" - folder. Open command prompt with administrative previleges, and see the directory
c:\Program Files\WindowsApps\your-app-id
If your database file deployed successfully, you can see it in the directory. If not, you may need to change the deploy settings.
To deploy the file to target machine, you should set the property of the one as ...
'BuildAction=Contents'
'Copy to output directory'='Always Copy'
You can set it from solution explorer and right-click the your database file.
If you succeeded the deploying file, your code will copy your database file to app local folder.
c:\Users\YOUR-USER-ID\AppData\Local\Packages\YOUR-APP-ID\LocalState
First, you would need to use await for your CopyDatabase method.
Second, I suggest you call this method in MainPage_Loaded event handler instead of MainPage's Constructor.
public MainPage()
{
this.InitializeComponent();
this.Loaded += MainPage_Loaded;
}
private async void MainPage_Loaded(object sender, RoutedEventArgs e)
{
gui = this; InitializeComponent();
await CopyDatabase();
DataSetup();
CreateNewChartButton.Visibility = Visibility.Collapsed;
SignInButton_Click(null, null);
}
I want to delete Read-only Folder. I did like this
//Remove Read-only for the Folder
File.SetAttributes(folderpath, File.GetAttributes(folderpath) & ~FileAttributes.ReadOnly);
//Delete Folder
FileInfo myfileinf = new FileInfo(folderpath);
myfileinf.Delete();
But i get this Error
"Access to the path 'E:\Working Folder\RPEssential\RPEssential\ResourcePlus-PL\RDLReports\t' is denied".
As I commented earlier the problem is that you are trying to delete a folder as you were deleting a file.
You should use Directory.Delete method to delete a folder.
In the following link there is a good example on how to use it
http://msdn.microsoft.com/en-au/library/fxeahc5f(v=vs.100).aspx
public static void Main()
{
// Specify the directories you want to manipulate.
string path = #"c:\MyDir";
string subPath = #"c:\MyDir\temp";
try
{
// Determine whether the directory exists.
if (!Directory.Exists(path))
{
// Create the directory.
Directory.CreateDirectory(path);
}
if (!Directory.Exists(subPath))
{
// Create the directory.
Directory.CreateDirectory(subPath);
}
// This will succeed because subdirectories are being deleted.
Console.WriteLine("I am about to attempt to delete {0}", path);
Directory.Delete(path, true);
Console.WriteLine("The Delete operation was successful.");
}
catch (Exception e)
{
Console.WriteLine("The process failed: {0}", e.ToString());
}
finally {}
}
There can be many reasons for a read only to be denied. Is the folder in use? Open in a console? Running an executable? All of these things you should check. Even if it has the permission, if the directory is in use, it won't allow you to delete it.

Recommended way to save uploaded files in a servlet application
(2 answers)
Closed 6 years ago.
When uploading 1-6969875-2644-t.jpg, the image is uploaded to
/home/xrcwrn/jvm/apache-tomcat-6.0.14/domains/xyz.com/ROOT/img/1-6969875-2644-t.jpg properly.
But I actually want to upload this image into the /home/xrcwrn/public_html/img folder.
I am using this code in Struts 2:
public String execute() {
try {
ServletContext servletContext = ServletActionContext.getServletContext();
String path =servletContext.getRealPath("/img");
System.out.println("Server path:" + path);
String filePath = servletContext.getRealPath(path);
File uploadDir = new File(filePath);
String relPath = uploadDir.getAbsolutePath();
//if the folder does not exits, creating it
if (uploadDir.exists() == false) {
uploadDir.mkdirs();
}
File fileToCreate = new File(path, this.userImageFileName);
FileUtils.copyFile(this.userImage, fileToCreate);
String pt = path + "/" + getUserImageFileName();
System.out.println("image path is :" + pt);
setImagePath(pt);
} catch (Exception e) {
e.printStackTrace();
addActionError(e.getMessage());
return INPUT;
}
System.out.println(" **************inside image upload***********");
return SUCCESS;
}
Don't use ServletContext#getRealPath(). You don't want to write uploaded files to there. They will get lost whenever you redeploy the webapp or even when you restart the server.
Replace
String path =servletContext.getRealPath("/img");
System.out.println("Server path:" + path);
String filePath = servletContext.getRealPath(path);
by
String filePath = "/home/xrcwrn/public_html/img";
If you want to make this configureable, consider providing it as a system property or a properties file setting.
I have a non-Java project that produces a versioned build artifact, and I want to upload this to a Nexus repository. Because the project isn't Java, it doesn't use Maven for builds. And I'd rather not introduce Maven/POM files just to get files into Nexus.
The links on blogs to the Nexus REST API all end up at a sign-in wall, with no "create user" link that I can see.
So, what's the best (or any reasonable) way to upload build artifacts to a Nexus repository without Maven? "bash + curl" would be great, or even a Python script.
Have you considering using the Maven command-line to upload files?
mvn deploy:deploy-file \
-Durl=$REPO_URL \
-DrepositoryId=$REPO_ID \
-DgroupId=org.myorg \
-DartifactId=myproj \
-Dversion=1.2.3 \
-Dpackaging=zip \
-Dfile=myproj.zip
This will automatically generate the Maven POM for the artifact.
Update
The following Sonatype article states that the "deploy-file" maven plugin is the easiest solution, but it also provides some examples using curl:
https://support.sonatype.com/entries/22189106-How-can-I-programatically-upload-an-artifact-into-Nexus-
Using curl:
curl -v \
-F "r=releases" \
-F "g=com.acme.widgets" \
-F "a=widget" \
-F "v=0.1-1" \
-F "p=tar.gz" \
-F "file=#./widget-0.1-1.tar.gz" \
-u myuser:mypassword \
http://localhost:8081/nexus/service/local/artifact/maven/content
You can see what the parameters mean here: https://support.sonatype.com/entries/22189106-How-can-I-programatically-upload-an-artifact-into-Nexus-
To make the permissions for this work, I created a new role in the admin GUI and I added two privileges to that role: Artifact Download and Artifact Upload. The standard "Repo: All Maven Repositories (Full Control)"-role is not enough.
You won't find this in the REST API documentation that comes bundled with the Nexus server, so these parameters might change in the future.
On a Sonatype JIRA issue, it was mentioned that they "are going to overhaul the REST API (and the way it's documentation is generated) in an upcoming release, most likely later this year".
You can ABSOLUTELY do this without using anything MAVEN related. I personally use the NING HttpClient (v1.8.16, to support java6).
For whatever reason, Sonatype makes it incredibly difficulty to figure out what the correct URLs, headers, and payloads are supposed to be; and I had to sniff the traffic and guess... There are some barely useful blogs/documentation there, however it is either irrelevant to oss.sonatype.org, or it's XML based (and I found out it doesn't even work). Crap documentation on their part, IMHO, and hopefully future seekers can find this answer useful. Many thanks to https://stackoverflow.com/a/33414423/2101812 for their post, as it helped a lot.
If you release somewhere other than oss.sonatype.org, just replace it with whatever the correct host is.
Here is the (CC0 licensed) code I wrote to accomplish this. Where profile is your sonatype/nexus profileID (such as 4364f3bbaf163) and repo (such as comdorkbox-1003) are parsed from the response when you upload your initial POM/Jar.

No need to use these commands .. you can directly use the nexus web Interface in order to upload your JAR using GAV parameters.
So it is very simple.
The calls that you need to make against Nexus are REST api calls.
The maven-nexus-plugin is a Maven plugin that you can use to make these calls. You could create a dummy pom with the necessary properties and make those calls through the Maven plugin.
Something like:
mvn -DserverAuthId=sonatype-nexus-staging -Dauto=true nexus:staging-close
Assumed things:
You have defined a server in your ~/.m2/settings.xml named sonatype-nexus-staging with your sonatype user and password set up - you will probably already have done this if you are deploying snapshots. But you can find more info here.
Your local settings.xml includes the nexus plugins as specified here.
The pom.xml sitting in your current directory has the correct Maven coordinates in its definition. If not, you can specify the groupId, artifactId, and version on the command line.
The -Dauto=true will turn off the interactive prompts so you can script this.
Ultimately, all this is doing is creating REST calls into Nexus. There is a full Nexus REST api but I have had little luck finding documentation for it that's not behind a paywall. You can turn on the debug mode for the plugin above and figure it out however by using -Dnexus.verboseDebug=true -X.
You could also theoretically go into the UI, turn on the Firebug Net panel, and watch for /service POSTs and deduce a path there as well.
In ruby https://github.com/RiotGames/nexus_cli A CLI wrapper around Sonatype Nexus REST calls.
Usage Example:
nexus-cli push_artifact com.mycompany.artifacts:myartifact:tgz:1.0.0 ~/path/to/file/to/push/myartifact.tgz
Configuration is done via the .nexus_cli file.
url: "http://my-nexus-server/nexus/"
repository: "my-repository-id"
username: "username"
password: "password"
You can also use the direct deploy method using curl. You don't need a pom for your file for it but it will not be generated as well so if you want one, you will have to upload it separately.
Here is the command:
version=1.2.3
artifact="myartifact"
repoId=yourrepository
groupId=org.myorg
REPO_URL=http://localhost:8081/nexus
curl -u nexususername:nexuspassword --upload-file filename.tgz $REPO_URL/content/repositories/$repoId/$groupId/$artifact/$version/$artifact-$version.tgz
for those who need it in Java, using apache httpcomponents 4.0:
public class PostFile {
protected HttpPost httppost ;
protected MultipartEntity mpEntity;
protected File filePath;
public PostFile(final String fullUrl, final String filePath){
this.httppost = new HttpPost(fullUrl);
this.filePath = new File(filePath);
this.mpEntity = new MultipartEntity();
}
public void authenticate(String user, String password){
String encoding = new String(Base64.encodeBase64((user+":"+password).getBytes()));
httppost.setHeader("Authorization", "Basic " + encoding);
}

}
public String post() throws ClientProtocolException, IOException {
HttpClient httpclient = new DefaultHttpClient();
httpclient.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1);
addParts();
httppost.setEntity(mpEntity);
HttpResponse response = httpclient.execute(httppost);
System.out.println("executing request " + httppost.getRequestLine());
System.out.println(httppost.getEntity().getContentLength());
HttpEntity resEntity = response.getEntity();
String statusLine = response.getStatusLine().toString();
System.out.println(statusLine);
if (resEntity != null) {
System.out.println(EntityUtils.toString(resEntity));
}
if (resEntity != null) {
resEntity.consumeContent();
}
return statusLine;
}
}
If you need a convenient command line interface or python API, look at repositorytools
Using it, you can upload artifact to nexus with command
artifact upload foo-1.2.3.ext releases com.fooware
To make it work, you will also need to set some environment variables
export REPOSITORY_URL=https://repo.example.com
export REPOSITORY_USER=admin
export REPOSITORY_PASSWORD=mysecretpassword
For recent versions of Nexus OSS (>= 3.9.0)
https://support.sonatype.com/hc/en-us/articles/115006744008-How-can-I-programmatically-upload-files-into-Nexus-3-
Example for versions 3.9.0 to 3.13.0:
curl -D - -u user:pass -X POST "https://nexus.domain/nexus/service/rest/beta/components?repository=somerepo" -H "accept: application/json" -H "Content-Type: multipart/form-data" -F "raw.directory=/test/" -F "raw.asset1=#test.txt;type=application/json" -F "raw.asset1.filename=test.txt"
You can manually upload the artifact's by clicking on upload artifacts button in the Nexus server and provide the necessary GAV properties for uploading(it's generally the file structure for storing the artifact)

I have a ASP.NET SOAP web service whose web method creates a PDF file, writes it to the "Download" directory of the applicaton, and returns the URL to the user. Code:
//Create the map images (MapPrinter) and insert them on the PDF (PagePrinter).
MemoryStream mstream = null;
FileStream fs = null;
try
{
//Create the memorystream storing the pdf created.
mstream = pgPrinter.GenerateMapImage();
//Convert the memorystream to an array of bytes.
byte[] byteArray = mstream.ToArray();
//return byteArray;
//Save PDF file to site's Download folder with a unique name.
System.Text.StringBuilder sb = new System.Text.StringBuilder(Global.PhysicalDownloadPath);
sb.Append("\\");
string fileName = Guid.NewGuid().ToString() + ".pdf";
sb.Append(fileName);
string filePath = sb.ToString();
fs = new FileStream(filePath, FileMode.CreateNew);
fs.Write(byteArray, 0, byteArray.Length);
string requestURI = this.Context.Request.Url.AbsoluteUri;
string virtPath = requestURI.Remove(requestURI.IndexOf("Service.asmx")) + "Download/" + fileName;
return virtPath;
}
catch (Exception ex)
{
throw new Exception("An error has occurred creating the map pdf.", ex);
}
finally
{
if (mstream != null) mstream.Close();
if (fs != null) fs.Close();
//Clean up resources
if (pgPrinter != null) pgPrinter.Dispose();
}
Then in the Global.asax file of the web service, I set up a Timer in the Application_Start event listener. In the Timer's ElapsedEvent listener I look for any files in the Download directory that are older than the Timer interval (for testing = 1 min., for deployment ~20 min.) and delete them. Code:
//Interval to check for old files (milliseconds), also set to delete files older than now minus this interval.
private static double deleteTimeInterval;
private static System.Timers.Timer timer;
//Physical path to Download folder. Everything in this folder will be checked for deletion.
public static string PhysicalDownloadPath;
void Application_Start(object sender, EventArgs e)
{
// Code that runs on application startup
deleteTimeInterval = Convert.ToDouble(System.Configuration.ConfigurationManager.AppSettings["FileDeleteInterval"]);
//Create timer with interval (milliseconds) whose elapse event will trigger the delete of old files
//in the Download directory.
timer = new System.Timers.Timer(deleteTimeInterval);
timer.Enabled = true;
timer.AutoReset = true;
timer.Elapsed += new System.Timers.ElapsedEventHandler(OnTimedEvent);
PhysicalDownloadPath = System.Web.Hosting.HostingEnvironment.ApplicationPhysicalPath + "Download";
}
private static void OnTimedEvent(object source, System.Timers.ElapsedEventArgs e)
{
//Delete the files older than the time interval in the Download folder.
var folder = new System.IO.DirectoryInfo(PhysicalDownloadPath);
System.IO.FileInfo[] files = folder.GetFiles();
foreach (var file in files)
{
if (file.CreationTime < DateTime.Now.AddMilliseconds(-deleteTimeInterval))
{
string path = PhysicalDownloadPath + "\\" + file.Name;
System.IO.File.Delete(path);
}
}
}
This works perfectly, with one exception. When I publish the web service application to inetpub\wwwroot (Windows 7, IIS7) it does not delete the old files in the Download directory. The app works perfect when I publish to IIS from a physical directory not in wwwroot. Obviously, it seems IIS places some sort of lock on files in the web root. I have tested impersonating an admin user to run the app and it still does not work. Any tips on how to circumvent the lock programmatically when in wwwroot? The client will probably want the app published to the root directory.
Your problem may be related to the fact that IIS reloads the Web Service Application if the directory or files contained in the main folder changes.
Try creating / deleting files in a temporary folder which is outside the root folder of your application (be aware of permissions on the folder to allow IIS to read/write files).
Instead of writing directly to the file system, why not use isolated storage?
http://msdn.microsoft.com/en-us/library/system.io.isolatedstorage.isolatedstorage.aspx
This should solve any location or permission based issues that you are having
I forgot to come back and answer my question.
I had to give the IIS_IUSRS group Modify permissions to the directory where I was reading/writing files.
Thanks to all those who answered.
