I am having some trouble with a asp.net MVC3 web application that I am developing. I need an upload page which Allows the user to upload excel files and dump them to the file system. I got this to work fine. The next part is the part that I am having trouble with, After I upload the excel files I need to programmatically kick off a SSIS package which I have created already to import the excel files.
Here is what I have so far in code:
//
// POST: /Home/Update/
[HttpPost]
public ActionResult Update(HttpPostedFileBase file)
{
// Verify that the user selected a file
if (file != null && file.ContentLength > 0)
{
var fileName = Path.GetFileName(file.FileName);
// store the file inside ~/App_Data/uploads folder
var path = Path.Combine(Server.MapPath("~/App_Data/uploads"), fileName);
ViewBag.Message = "File Uploaded Successfully";
file.SaveAs(path);
}
//Start the SSIS here
try
{
Application app = new Application();
Package package = null;
package = app.LoadPackage( #"C:\Users\Chris\Documents\Visual Studio
2008\Projects\Integration Services Project1\Integration Services Project1
\bin\Package.dtsx", null);
// Execute Package
DTSExecResult results = package.Execute();
if(results == DTSExecResult.Failure)
{
foreach(DtsError local_DtsError in package.Errors)
{
ViewBag.Message("Package Execution results:{0}",
local_DtsError.Description.ToString());
}
}
}
catch(DtsException ex)
{
//ViewBag.Message("{0} Exception caught.", ex);
}
// redirect back to the index action to show the form once again
return RedirectToAction("Update");
}
When I run the code and upload an excel file I get a DtsException caught, which says:
Failed to open package file "C:\Users\Chris\Documents\Visual Studio 2008\Projects\Integration Services Project1\Integration Services Project1\bin\Package.dtsx" due to error 0x80070003 "The system cannot find the path specified.". This happens when loading a package and the file cannot be opened or loaded correctly into the XML document. This can be the result of either providing an incorrect file name was specified when calling LoadPackage or the XML file was specified and has an incorrect format.
I don't understand why it is giving me this because the file path is right I checked and it is exactly correct. I need some help fixing this issue I would greatly appreciate any help you guys can give.
Permissions I should think. Put the file somewhere where account running IIS can see it. Whereever you were planning on deploying it, would be good.

I have a use case where I have to read a config.json file from an AppService and based on the configuration in json file I have to generate an ID.
I am using following piece of code to generate the Uri so that I can open the file using StorageFile.GetFileFromApplicationUriAsync(fileUri).
Uri fileUri = null;
try
{
Debug.WriteLine("Creating new uri");
fileUri = new Uri(fileName);
if (fileUri == null)
{
Debug.WriteLine("Uri creation failed");
} else
{
Debug.WriteLine("New Uri created");
}
} catch (Exception ex)
{
Debug.WriteLine("Uri creation failed" + ex.Message);
}
Now when I am trying to debug this code my debugger is disappearing after line with new Uri(fileName)
If I just let the code run with no breakpoints I am not seeing any message after Creating new uri. Not even an exception.
Value of fileName is "ms-appx:///config/config.json"
Can anyone please explain what is wrong here? Also is it possible to open and read a file from an AppService?

The uri use appx only can read the resource is content in msbuild.
You can right click the file and select the property and you should select the file's build action as content.

Sorry, my visual studio's language is local language.But the visual studio's have the same layout.
I am making a Windows Store application and I want to allow users that press an "Export To Word" button to have all the data that they have input into the app to be displayed in a Word document and saved to a desired location on their computer. The code below is a test segment of code that almost does what I am after, however after saving the document and opening it using Word rather than the app, it cannot open the file due to it being corrupted apparently. However when you open it in Notepad the text is displayed as I want.
private async void exportToWord_Click(object sender, RoutedEventArgs e)
{
await ExportToWord();
}
private async Task ExportToWord()
{
// Create the picker object and set options
Windows.Storage.Pickers.FileSavePicker savePicker = new Windows.Storage.Pickers.FileSavePicker();
savePicker.SuggestedStartLocation = Windows.Storage.Pickers.PickerLocationId.DocumentsLibrary;
// Dropdown of file types the user can save the file as
savePicker.FileTypeChoices.Add("Word", newList<string>{".docx"});
// Default file name if the user does not type one in or select a file to replace
savePicker.SuggestedFileName = "Test";
Windows.Storage.StorageFile file = await savePicker.PickSaveFileAsync();
MessageDialog mD;
if (file != null)
{
// Prevent updates to the remote version of the file until we finish
// making changes and call CompleteUpdatesAsync.
Windows.Storage.CachedFileManager.DeferUpdates(file);
// write to file
await Windows.Storage.FileIO.WriteTextAsync(file, createContentsOfFile());
// Let Windows know that we're finished changing the file so the other
// app can update the remote version of the file.
// Completing updates may require Windows to ask for user input.
Windows.Storage.Provider.FileUpdateStatus updateStatus = await Windows.Storage.CachedFileManager.CompleteUpdatesAsync(file);
if (updateStatus == Windows.Storage.Provider.FileUpdateStatus.Complete)
{
mD = newMessageDialog("Connect exported to:" + file, "Export Successful");
}
else
{
mD = newMessageDialog("Could not save file. Try again", "Export Unsuccessful");
}
}
else
{
mD = newMessageDialog("Operation canceled because the file could not be found. Try again", "Export Unsuccessful");
}
await mD.ShowAsync();
}
private string createContentsOfFile()
{
return "Testing...";
}
I believe the issue is that I am outputting plain text to the Word document but it needs to be in a certain format to be output correctly and be displayed in a Word doc. Is there any way of doing this in Windows Store apps?
Any help would be appreciated.
I'm not aware of any Word doc components available for Windows Runtime apps (Microsoft doesn't provide one, but there could be a third party component I'm not aware of).
You can get documentation on the docx format and for simple text it may not be too complex (I'm not sure), or you can use another format which Word can open.
If you don't need formatting I'd probably stick with txt.
If you need small amounts of formatting then rtf is a good option. It is fairly simple to generate yourself or the RichEditBox can export RTF format text which you can then save into a .doc file and open in Word.
I have some code that saves an xml file to the file system.
public static void Save(T obj, string FileName)
{
if (Application.Current.HasElevatedPermissions)
{
string myDocuments = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
string path = System.IO.Path.Combine(myDocuments, FileName);
using (var writer = new StreamWriter(path))
{
var serializer = new XmlSerializer(typeof(T));
serializer.Serialize(writer, obj);
writer.Flush();
}
}
else
{
throw new Exception("Cannot Save File. Application Requires Elevated permissions.");
}
}
While debugging using Internet Explorer 10 the file is not saved to the listed path in the path variable "C:\Users\Travis\Documents\Save.xml"
I call load with the exact same path "C:\Users\Travis\Documents\Save.xml" and the file loads correctly but the file still does not exist at the listed location.
I searched the file system with no results for Save.xml but it has to exist since it is able to load after application exit.
If I access the same page using Chrome the file is created successfully at the location.
I am wondering where Internet Explorer saves the file?
I found that if I uncheck "Enable Protected Mode" in IE's Security tab then the file is created in the location as expected.
I am dynamically downloading a XAP file that has an embedded resource assembly, with a single resource file (ApplicationStrings.fr-CA.resx). I am using WebClient to pull down the XAP file and using the following code to load the assembly, based on work done by Jeff Prosise in this post: http://www.wintellect.com/CS/blogs/jprosise/archive/2010/06/21/dynamic-localization-in-silverlight.aspx.
Note that I also manually create the XAP file from the fr-CA folder with assembly and the ApplicationManifest.xaml, as described by Guy Smith-Ferrier's steps listed in his presentation here http://www.guysmithferrier.com/post/2010/10/Building-Localized-XAP-Resource-Files-For-Silverlight-4.aspx.
// Get the application manifest from the downloaded XAP
StreamResourceInfo sri = new StreamResourceInfo(e.Result, null);
XmlReader reader = XmlReader.Create(Application.GetResourceStream(sri, new Uri("AppManifest.xaml", UriKind.Relative)).Stream);
AssemblyPartCollection parts = new AssemblyPartCollection();
// Enumerate the assemblies in the downloaded XAP
if (reader.Read())
{
reader.ReadStartElement();
if (reader.ReadToNextSibling("Deployment.Parts"))
{
while (reader.ReadToFollowing("AssemblyPart"))
{
parts.Add(new AssemblyPart() { Source = reader.GetAttribute("Source") });
}
}
}
// Load the satellite assemblies
foreach (AssemblyPart part in parts)
{
if (part.Source.ToLower().Contains("resources"))
{
Stream assembly = Application.GetResourceStream(sri, new Uri(part.Source, UriKind.Relative)).Stream;
part.Load(assembly);
}
}
// Change the culture
Thread.CurrentThread.CurrentCulture = culture;
Thread.CurrentThread.CurrentUICulture = culture;
The assembly seems to load ok, and I have matched up namespaces with the default resource file (ApplicationStrings.resx) with the downloaded resource file (ApplicationStrings.fr-CA.resx). As seen the code, the culture is set for the current thread.
However, calls to ApplicationStrings.ResourceManager.GetString(...) do not return the resources for the set culture. For example, the following should return a string for the new culture (fr-CA), but always returns the default culture (en-US).
/// <summary>
/// Looks up a localized string similar to User Name:.
/// </summary>
public static string Label_UserName {
get {
return ResourceManager.GetString("Label_UserName", resourceCulture);
}
}
Any suggestions? Thanks.
** UPDATE
I figured it out...I had forgotten to reset my supported locals in my satellite assembly project file:
<SupportedCultures>fr-CA</SupportedCultures>
I also made my folder structure exactly as it is for the default resources in my main Silverlight application.
Ok so, basically my problem is with reading and XML file from IsolatedFileStorage. I'll go through the process that leads to my error and then I'll list the relevant code and XML file.
On the first execution it recognises that the file does not exist - it therefore creates the file in IsolatedFileStorage
On the second execution it can now see that the file does exist and so it loads the XML file
On the third execution it can see that it exists - but it throws an XML error
I cannot for the life of me find a solution to it (link to other discussion on MSDN here)
So the code for reading/creating the XML file in IsolatedFileStorage is as follows:
try
{
/***********************
* CHECK THE SETTINGS
********************/
if (store.FileExists("AppSettings.xml"))
{
streamSettings = new IsolatedStorageFileStream("AppSettings.xml", System.IO.FileMode.Open, store);
DebugHelp.Text = "AppSettings.xml exists... Loading!";
streamSettings.Seek(0, System.IO.SeekOrigin.Begin);
xmlDoc = XDocument.Load(streamSettings, LoadOptions.None);
}
else
{
streamSettings = new IsolatedStorageFileStream("AppSettings.xml", System.IO.FileMode.Create, store);
DebugHelp.Text = "AppSettings.xml does not exist... Creating!";
xmlDoc = XDocument.Load("AppSettings.xml", LoadOptions.None);
}
if (xmlDoc != null)
xmlDoc.Save(streamSettings);
}
catch (Exception e)
{
DebugHelp.Text = e.ToString();
}
finally
{
streamSettings.Close();
}
And the related XML file is as follows:
<?xml version="1.0" encoding="utf-8" ?>
<Settings>
</Settings>
Extremely advanced I know - however it throws the following error (here) and you can find the full error text at the bottom of the Social.MSDN page.
Please help - I have been looking for a solution (as the one on the social.msdn site didn't work) for about 2 weeks now.
Why don't you try to read file using a simple StreamReader ? Below a part of a method I have created to readfile from store. Have a try, check your content, and then try loading xml from String (XDocument.Parse etc ...)
String fileContent = String.Empty;
using (_store = IsolatedStorageFile.GetUserStoreForApplication())
{
if (_store.FileExists(file))
{
_storeStream = new IsolatedStorageFileStream(file, FileMode.Open, _store);
using (StreamReader sr = new StreamReader(_storeStream))
{
fileContent = sr.ReadToEnd();
}
__storeStream.Close();
return fileContent;
}
else {
return null;
}
}
It looks to me like the problem is in your save method - it looks like you are maybe appending the settings each time you close - to overwrite your existing settings, you need to ensure that you delete your existing file and create a new one.
To help debug this, try using http://wp7explorer.codeplex.com/ - this might help you see the raw file "on disk"
As an aside, for settings in general, do check out the AppSettings that IsolatedStorage provides by default - unless you have complicated needs, then these may suffice on their own.
Your code sample isn't complete so it's hard to say for sure but, rather than just seeking to the start of the file you may find it easier to just delete it if it already exists. You can do this with FileMode.Create. In turn this means you can do away with the need to check for the existing file.
I suspect that the problem is that you are writing a smaller amount of text to the file on subsequent attempts and so leaving part of the original/previous text behind. In turn this creates a file which contains invalid XML.
