When I retrieve all Files (and Folders) of my GoogleDrive Account I should get something like 1500 List elements back, but I get a bit more than 3000 back. I looked into the List and found that some files are 2-3 times in it. Why is that?
Here is the code I use to retrieve the files:
public async Task<List<File>> RetrieveAllFilesAsList(DriveService service, string query = null)
{
List<File> result = new List<File>();
FilesResource.ListRequest request = service.Files.List();
if (query != null)
{
request.Q = query;
}
do
{
try
{
FileList files = await request.ExecuteAsync();
result.AddRange(files.Items);
request.PageToken = files.NextPageToken;
}
catch (Exception e)
{
Console.WriteLine("An error occurred (from RetrieveAllFilesAsList): " + e.Message);
request.PageToken = null;
}
}
while (!String.IsNullOrEmpty(request.PageToken));
return result;
}
Update1:
public async Task<List<File>> RetrieveAllFilesAsList(DriveService service, string query = null)
{
List<File> result = new List<File>();
FilesResource.ListRequest request = service.Files.List();
request.MaxResults = 1000;
if (query != null)
{
request.Q = query + " AND trashed=false";
}
else
{
request.Q = "trashed=false";
}
do
{
try
{
FileList files = await request.ExecuteAsync();
result.AddRange(files.Items);
request.PageToken = files.NextPageToken;
}
catch (Exception e)
{
Console.WriteLine("An error occurred (from RetrieveAllFilesAsList): " + e.Message);
request.PageToken = null;
}
}
while (!String.IsNullOrEmpty(request.PageToken));
int i;
for (i = 0; i < result.Count; i++ )
{
System.IO.File.AppendAllText(#"C:\Users\carl\Desktop\log.txt", result[i].Id + "\t" + result[i].Title + "\t" + result[i].ExplicitlyTrashed.ToString() + "\r\n");
}
// prints 3120 Lines
System.IO.File.AppendAllText(#"C:\Users\carl\Desktop\log.txt", "" + i + Environment.NewLine);
//Count = 3120
System.IO.File.AppendAllText(#"C:\Users\carl\Desktop\log.txt", "" + result.Count);
return result;
}
Word failed to give me the right the linecount, so I did it over my Function.
But I can find the FileId 2-3 times in the File.
I cannot write on the comments yet, so according to the API
from google
"Note: This method returns all files by default. This includes files with trashed=true in the results. Use the trashed=false query parameter to filter these from the results."
So can you check what url of the rest api is actually being called? It seems you need to put some filters on the List method.

I am using PDFBox 1.8.3 and my need is to take a set of ZPLs and convert them all into one PDF. For the conversion part(ZPL to PDF), we are using labelary and this works correctly. I am basically using PDFBox to "stitch" all these individual PDFs. My source code is very simple as below :
var outputByteStream = new ByteArrayOutputStream();
var destinationDoc = null;
var doc = null;
for each(var img in images.toArray()) {
log.debug("Working with image : " + img);
if("ZPL".equalsIgnoreCase(img.getFormat()) || "ZPL203".equalsIgnoreCase(img.getFormat())) {
try {
var convertorServiceUrl = "http://labelary ...." + img.getId()+"?labelSize=4x6&density=8dpmm";
var urlObject = new URL(convertorServiceUrl);
var conn = urlObject.openConnection();
conn.connect();
if(destinationDoc == null ) {
var tmpfile = java.io.File.createTempFile(pw +"-"+uniqKey, ".pdf");
var raf = new org.apache.pdfbox.io.RandomAccessFile(tmpfile, "rw");
destinationDoc = PDDocument.load(conn.getInputStream(), raf);
}
else {
doc = PDDocument.load(conn.getInputStream());
if (doc != null && doc.getNumberOfPages() > 0) {
var page = doc.getDocumentCatalog().getAllPages().get(0);
destinationDoc.importPage(page);
}
}
} catch (res) {
log.error("Error message retrieved is " + exceptionMsg);
throw new BaseRuntimeException("Unable to convert the PDF for image with id " + img.getId(), res);
}
}
}
try {
if(destinationDoc != null) {
destinationDoc.save(outputByteStream);
destinationDoc.close();
}
} catch (e1) {
log.error("Error in writing the document to the output stream " + pw + "." , e1);
throw e1;
}
return outputByteStream.toByteArray();
Source code runs and generates a PDF but all the pages of the PDF are pointing to the first page. So if my for-loop run 4 times, all 4 pages of the PDF are for first label.
If I use addPage like below
var outputByteStream = new ByteArrayOutputStream();
var destinationDoc = new PDDocument();
var doc = null;
for each(var img in images.toArray()) {
log.debug("Working with image : " + img);
if("ZPL".equalsIgnoreCase(img.getFormat()) || "ZPL203".equalsIgnoreCase(img.getFormat())) {
try {
var convertorServiceUrl = "http://labelary ...." + img.getId()+"?labelSize=4x6&density=8dpmm";
var urlObject = new URL(convertorServiceUrl);
var conn = urlObject.openConnection();
conn.connect();
doc = PDDocument.load(conn.getInputStream());
if (doc != null && doc.getNumberOfPages() > 0) {
var page = doc.getDocumentCatalog().getAllPages().get(0);
destinationDoc.addPage(page);
}
} catch (res) {
log.error("Error message retrieved is " + exceptionMsg);
throw new BaseRuntimeException("Unable to convert the PDF for image with id " + img.getId(), res);
}
}
}
try {
if(destinationDoc != null) {
destinationDoc.save(outputByteStream);
destinationDoc.close();
}
} catch (e1) {
log.error("Error in writing the document to the output stream " + pw + "." , e1);
throw e1;
}
return outputByteStream.toByteArray();
Then the result is a PDF page with all empty pages.
I have already ensured that the content returned from the labelary service is correct and if I simply take the response and save it into a file it works correctly. Even saving the PDDocument one page at a time also produces the PDF correctly.
The problem I have is with the "stitching" of PDFs. It should work as per the documentation but I am not sure what I am doing wrong.
I've looked at Parallel.ForEach - System Out of Memory Exception regarding this issue but not much of a solution was given. I'm very new to using Parallel.ForEach, so I'm trying to figure out what's going on.
Diagnostic tools caps out at 1023 repeating (I understand this is an x86 to x64 arch restriction, but I wanted to offer the program in both formats.) I also don't feel like any program should ever meet that threshold. When I compile the program in x64, I sit around 1.1-1.4GB with MaxDegree . For sake of testing, I am running GC.Collection() at the end of each Parallel.ForEach iteration (I understand this isn't good practice, I'm just trying to troubleshoot at this point.)
Here's what I'm seeing:
Now if I try to use a Partitioner method, such as:
var checkforfinished = Parallel.ForEach<ListViewItem>(Partitioner.Create(0,lstBackupUsers.Items.Count), lstBackupUsers.Items.Cast<ListViewItem>(), opts, name =>
The I get an error of:
"No overload for method 'ForEach' takes 4 arguments"
That's fine, I modify my Parallel.ForEach statement so it looks like this:
var checkforfinished = Parallel.ForEach(Partitioner.Create(0,lstBackupUsers.Items.Count), lstBackupUsers.Items, opts, name => (I removed my casts)
and then my ForEach method won't accept the statement because it wants me to explicitly tell it that it's addressing a listviewbox.items method.
I am so confused on what to do.
Do I create a Partitioner, and if I do, how do I make my Parallel.ForEach method understand how to address a listviewbox?
update 1
I want to try to give as many details as possible because this is just rough. I'm sure it's easy, I'm just overcomplicationg it by an nth degree.
I have my Parallel.ForEach(//) running in a background worker function. My DoWork process is over 300 lines (I'm not an expert in C#, I'm just putting things together for a program at work.)
Here are bullet points of its basic structure
User clicks a "Start backup" button as seen in the screenshot
Button begins a separate function that checks to see which method the user selected to grab a list of usernames from (LDAP or flat text file)
That function then sends off a bgw_dowork() request
Inside the DoWork request, it looks like a summary of:
Check preliminary statements (bgw.cancellationpending for example)
Move on to grabbing some settings from the configurationmanager.appsettings
Begin the "complex" Parallel.ForEach command which Reads the listbox record rows and foreach row performs a very long list of commands to complete an operation for one user
The entire program, especially bgw_dowork heavily uses Google's v3 Drive API to login as a user, grab a file as recorded by other functions that prepare the user directory to be backed up (separate functions which login as a user, record their files (and fileIds) and their directories/subdirectories) and the bgw_dowork performs a chunk of the actual download functionality, which then calls off to the other functions to finish moving the files after they have been downloaded.
The actual "code" I use is (and I promise it's not pretty...)

I have a timer which runs very fast, every 10ms.

_DoDownload(DoubleDimList[i][y], ref mp3ToPlay);
if (muted) Mute(0);

Now this timer handles the download in the background in a Global scope.
The _DoDownload methos which basically starts the entire process looks like this
private void _DoDownload(string dArtist, ref string dPath)
{
if (!Contain && skip <= 3 && !Downloading)

fs.Close();
System.IO.File.Delete(path);
Contain = false;
skip += 1;
Downloading = false;
}
} }
catch(Exception Ex)
{
MessageBox.Show("Downloading error: " + Ex.Message);
}
}
}
Now once the exception is thrown it messes up the entire project. As you see in the last method, if _InetGetHTMLSearch doesn't update the search(returns nothing) I am skipping and moving to next search. However the exception will be thrown in every next search. I tried setting new cookies in every search but still didn't work.
Any solutions how to avoid this issue?
P.S. I have to say that if I change the timer's Interval to 500ms it will download more mp3 before the exception is thrown but not all of them.
Edit: The issue here is obvious. The request timesout but even if I set it to Timeout.Infinite it will hand there forever

The problem is that your try...catch is outside of your for loop. The first exception will exit the for loop, append the message to textBox1, then exit the button handler.
If you want to keep looping through even if there is an error, move the try...catch inside of the loop. Here's an example:
for( hola = 0; hola < data.Count(); hola++)
{
var url = #"https://mail.google.com/mail/feed/atom";
var encoded = TextToBase64(data[0].UserName + ":" + data[1].Password);
var myweb = HttpWebRequest.Create(url) as HttpWebRequest;
myweb.Method = "POST";
myweb.ContentLength = 0;
myweb.Headers.Add("Authorization", "Basic " + encoded);
try
{
var response = myweb.GetResponse();
var stream = response.GetResponseStream();
textBox1.Text += ("Connection established with");
MessageBox.Show(hola.ToString());
}
catch (Exception ex)
{
textBox1.Text += ("Error connection. Original error: " + ex.Message);
}
}
i want to upload a list of .txt, and keep them in a custom folder on skydrive
like Someone's Account -> Skydrive -> custom folder ('testfile')
i have tried
LiveOperationResult res = await client.BackgroundUploadAsync("me/skydrive/testfile", new Uri("/shared/transfers/" + t, UriKind.Relative),OverwriteOption.Overwrite);,
but it doesn't work at all, it give me an error of:
The URL contains the path 'testfile', which isn't supported.
if i need to get folder ID to upload the file, how do i get the ID?
here is my code:
private async void button_Click(object sender, EventArgs e)
{
IsolatedStorageFile isoStore = IsolatedStorageFile.GetUserStoreForApplication();
var temptempout = new List<String>(isoStore.GetFileNames("*").ToList());
int total = temptempout.Count;
int now = 0;
if (temptempout.Count > 0)
{
ShowTextDebug.Text = "Uploaded 0 of " + total + " files";
foreach (String t in temptempout)
{
using (var fileStream = isoStore.OpenFile(t, FileMode.Open, FileAccess.Read))
{
try
{
LiveOperationResult res = await client.BackgroundUploadAsync("me/skydrive/testfile",
new Uri("/shared/transfers/" + t, UriKind.Relative),
OverwriteOption.Overwrite
);
}
catch (Exception err)
{
String rrtt = "there is an error while uploading txt " + err.Message;
MessageBox.Show(rrtt, "error", MessageBoxButton.OK);
}
}
now++;
ShowTextDebug.Text = "Uploaded " + now + " of " + total + " files";
}
ShowTextDebug.Text += "\nupload complete";
}
else
{
MessageBox.Show("no txt exist", "error", MessageBoxButton.OK);
}
}
thanks for helping me
You need to get the folder id first. You can do it as follows:
private async Task<string> GetSkyDriveFolderID(string folderName)
{
client = App.LiveClient;
LiveOperationResult operationResult = await client.GetAsync("me/skydrive/files?filter=folders");
var iEnum = operationResult.Result.Values.GetEnumerator();
iEnum.MoveNext();
var folders = iEnum.Current as IEnumerable;
foreach (dynamic v in folders)
{
if (v.name == folderName)
{
return v.id as string;
}
}
return null;
}
Call this method before uploading the file to get the folder id:
string folderId = await GetSkyDriveFolderId("folderName");
LiveOperationResult res = await client.BackgroundUploadAsync(folderId, new Uri("/shared/transfers/" + t, UriKind.Relative), OverwriteOption.Overwrite);
