I want to access all files attached to the current project. Im not able to find any files using the PXSelect statement below.
My Code
public PXSelect<UploadFile, Where<UploadFile.name, Like<Current<PMProject.contractCD>>>> Files;
string files = "";
foreach (UploadFile f in Files.Select())
{
files += "\n"+f.FileID;
}
Static GetFileNotes method of the PXNoteAttribute returns the list of identifiers of files attached to a record. Below is a code snippet showing how to retrieve all files attached to the current project:
public class ProjectEntryExt : PXGraphExtension<ProjectEntry>
{
public PXAction<PMProject> GetFiles;
[PXButton]
[PXUIField(DisplayName = "Get Files")]
protected void getFiles()
{
var projectCache = Base.Caches[typeof(PMProject)];
Guid[] files = PXNoteAttribute.GetFileNotes(projectCache, projectCache.Current);
foreach (Guid fileID in files)
{
var fm = new PX.SM.UploadFileMaintenance();
PX.SM.FileInfo fi = fm.GetFileWithNoData(fileID);
}
}
}

We're making an ASP.Net MVC app that needs to be able to generate a PDF and display it to the screen or save it somewhere easy for the user to access. We're using PdfSharp to generate the document. Once it's finished, how do we let the user save the document or open it up in a reader? I'm especially confused because the PDF is generated server-side but we want it to show up client-side.
Here is the MVC controller to create the report that we have written so far:
public class ReportController : ApiController
{
private static readonly string filename = "report.pdf";
[HttpGet]
public void GenerateReport()
{
ReportPdfInput input = new ReportPdfInput()
{
//Empty for now
};
var manager = new ReportPdfManagerFactory().GetReportPdfManager();
var documentRenderer = manager.GenerateReport(input);
documentRenderer.PdfDocument.Save(filename); //Returns a PdfDocumentRenderer
Process.Start(filename);
}
}
When this runs, I get an UnauthorizedAccessException at documentRenderer.PdfDocument.Save(filename); that says, Access to the path 'C:\Program Files (x86)\Common Files\Microsoft Shared\DevServer\10.0\report.pdf' is denied. I'm also not sure what will happen when the line Process.Start(filename); is executed.
This is the code in manager.GenerateReport(input):
public class ReportPdfManager : IReportPdfManager
{
public PdfDocumentRenderer GenerateReport(ReportPdfInput input)
{
var document = CreateDocument(input);
var renderer = new PdfDocumentRenderer(true, PdfSharp.Pdf.PdfFontEmbedding.Always);
renderer.Document = document;
renderer.RenderDocument();
return renderer;
}
private Document CreateDocument(ReportPdfInput input)
{
//Put content into the document
}
}
Using Yarx's suggestion and PDFsharp Team's tutorial, this is the code we ended up with:
Controller:
[HttpGet]
public ActionResult GenerateReport(ReportPdfInput input)
{
using (MemoryStream stream = new MemoryStream())
{
var manager = new ReportPdfManagerFactory().GetReportPdfManager();
var document = manager.GenerateReport(input);
document.Save(stream, false);
return File(stream.ToArray(), "application/pdf");
}
}
ReportPdfManager:
public PdfDocument GenerateReport(ReportPdfInput input)
{
var document = CreateDocument(input);
var renderer = new PdfDocumentRenderer(true,
PdfSharp.Pdf.PdfFontEmbedding.Always);
renderer.Document = document;
renderer.RenderDocument();
return renderer.PdfDocument;
}
private Document CreateDocument(ReportPdfInput input)
{
//Creates a Document and puts content into it
}
I'm not familar with PDF sharp but for MVC is mostly done via built in functionality. You need to get your pdf document represented as an array of bytes. Then you'd simply use MVC's File method to return it to the browser and let it handle the download. Are there any methods on their class to do that?
public class PdfDocumentController : Controller
{
public ActionResult GenerateReport(ReportPdfInput input)
{
//Get document as byte[]
byte[] documentData;
return File(documentData, "application/pdf");
}
}
I need to recurse through the contents of a document library and display them on a webpage using MVC. However I get the following error when trying to run my code: " The collection has not been initialized. It has not been requested or the request has not been executed. It may need to be explicitly requested."
Any help would be appreciated!
Here is my code:
public class HomeController : Controller
{
public ActionResult Index()
{
DefaultModel model = new DefaultModel();
using (ClientContext context = new ClientContext("MySPSite"))
{
List list = context.Web.Lists.GetByTitle("DocumentLibrary");
Folder rootFolder = list.RootFolder;
IEnumerable<SharePointItemBaseModel> items = ProcessFolder(rootFolder);
model.items.AddRange(items);
}
return View(model);
}
public IEnumerable<SharePointItemBaseModel> ProcessFolder(Folder folder)
{
List<SharePointItemBaseModel> listItems = new List<SharePointItemBaseModel>();
foreach (Folder childFolder in folder.Folders)
{
FolderModel folderModel = new FolderModel();
IEnumerable<SharePointItemBaseModel> childFolders = ProcessFolder(childFolder,context);
folderModel.Items.AddRange(childFolders);
listItems.Add(folderModel);
}
foreach (Microsoft.SharePoint.Client.File file in folder.Files)
{
DocumentModel documentModel = new DocumentModel();
documentModel.Name = file.Title;
documentModel.modifiedBy = file.ModifiedBy.ToString();
listItems.Add(documentModel);
}
return listItems;
}
public ActionResult About()
{
return View();
}
}
}
I managed to fix this myself.
In my recursive method I just used
context.Load(folder.Folders);
and
context.Load(folder.Files);
this initialized the collection allowing me to use it in my foreach loops
I am using svnkit-1.3.5.jar in my application. On one of my screens on clicking a button I need to display a jQuery dialog box containing list of folders present at a particular path in SVN. Does svnkit provide any method that retrieves all folder names present at a specific location? How do I achieve this in java?
Here is the code i use for the same purpose (uses svnkit library). Modified version of #mstrap's code for better clarity.
public static String NAME = "svnusername";
public static String PASSWORD = "svnpass";
public final String TRUNK_VERSION_PATH = "svn://192.168.1.1/path";
public static List<String> apiVersions;
public List<String> getApiVersion() {
logger.info("Getting API Version list....");
apiVersions = new ArrayList<String>();
SVNURL repositoryURL = null;
try {
repositoryURL = SVNURL.parseURIEncoded(TRUNK_VERSION_PATH);
} catch (SVNException e) {
logger.error(e);
}
SVNRevision revision = SVNRevision.HEAD;
SvnOperationFactory operationFactory = new SvnOperationFactory();
operationFactory.setAuthenticationManager(new BasicAuthenticationManager(NAME, PASSWORD));
SvnList list = operationFactory.createList();
list.setDepth(SVNDepth.IMMEDIATES);
list.setRevision(revision);
list.addTarget(SvnTarget.fromURL(repositoryURL, revision));
list.setReceiver(new ISvnObjectReceiver<SVNDirEntry>() {
public void receive(SvnTarget target, SVNDirEntry object) throws SVNException {
String name = object.getRelativePath();
if(name!=null && !name.isEmpty()){
apiVersions.add(name);
}
}
});
try {
list.run();
} catch (SVNException ex) {
logger.error(ex);
}
return apiVersions;
}
Cheers!!

I've put together a function that creates a sharepoint folder in a document library based on the url that's past in as an argument. The code works and the folder shows up in sharepoint from the webapplication.
However, when I query the SPWeb object for the folder afterward, it says the folder doesnt exist. Which makes no sense to me. Stranger still, is that this very same code worked no too long ago. I had been using it to create tree structures in sharepoint.
Even if the query folder fails, the GetFolder still returns a the folder, but when I add files to the returned folder, I get a runtime exception indicating that the file doesn't exist...which I assume means the folder I am trying to add it to doesn't exist since the file I am adding, doesn't exist yet. Which is why I am adding it.
So my question is, why am I getting this error, and why does FolderExists return false when the folder actually exists? We know it exists because GetFolder actually returns it...
I've included some actual code from the app to make things clear.
If someone could have a look at the code and see and anything jumps out at them, that would be fantabulous...Thanks
Code to build folders:
public void CreateFolder(SPUriBuilder url)
{
try
{
Log.Instance.WriteToLog("CreateFolder({0})", url);
var library = GetLibrary(url.Library);
if (library != null)
{
// parse out string data
//
var parent = library.RootFolder.ServerRelativeUrl;
var segments = url.Account.Split(new char[] { '/' }, StringSplitOptions.RemoveEmptyEntries);
var path = parent;
// get default folder collection
//
SPFolderCollection subFolders = _web.GetFolder(parent).SubFolders;
// check for sub-folders to create
//
if (segments.Length > 0)
{
int i = 0;
do
{
// check for folder and create if non-existant
//
var buildPath = String.Format("{0}/{1}", path, segments[i]);
if (_web.GetFolder(buildPath).Exists == false)
_web.GetFolder(path).SubFolders.Add(segments[i]);
// retrieve new sub-folder collection
//
subFolders = _web.GetFolder(buildPath).SubFolders;
path = buildPath;
// next folder in path
//
i++;
}
while (i < segments.Length);
}
// finally, add folder of interest
//
subFolders.Add(url.Folder);
}
}
catch (Exception e)
{
throw new SPImportException("Exception: {0}, creating folder: {1} in Library: {2}", e.Message, url.Folder, url.Library);
}
}
Code to Query folder:
public bool FolderExists(SPUriBuilder url)
{
return _web.GetFolder(url.Uri.LocalPath).Exists;
}
Code to Get Folder:
private SPFolder GetFolder(SPUriBuilder url)
{
return _web.GetFolder(url.Uri.LocalPath);
}
The SPUriBuilder is a custom class I created to assemble the Uri:
public class SPUriBuilder
{
public string SiteUrl { get; private set; }
public string Library { get; private set; }
public string Parent { get; private set; }
public string Folder { get; private set; }
public string File { get; private set; }
public string Account { get; private set; }
public Uri Uri { get; private set; }
public SPUriBuilder(string siteUrl, string library, string account, string parent, string folder)
{
this.SiteUrl = siteUrl;
this.Library = library;
this.Account = account;
this.Parent = parent.Replace("\\", "/");
this.Parent = this.Parent.StartsWith("/") ? this.Parent.Substring(1) : this.Parent;
this.Folder = folder;
StringBuilder url = new StringBuilder();
url.AppendFormat("{0}/{1}/{2}", SiteUrl, Library, Account);
if (String.IsNullOrEmpty(Parent) == false)
url.AppendFormat("/{0}", Parent);
url.AppendFormat("/{0}", Folder);
this.Uri = new Uri(url.ToString());
}
public SPUriBuilder(SPUriBuilder uri, string file)
: this(uri.SiteUrl, uri.Library, uri.Account, uri.Parent, uri.Folder)
{
this.File = file;
StringBuilder url = new StringBuilder();
url.AppendFormat("{0}/{1}", this.Uri.ToString(), this.File);
this.Uri = new Uri(url.ToString());
}
public override string ToString()
{
return Uri.ToString();
}
}
I found the answer this to this myself. The problem was in the code used to create the folder.
var parent = library.RootFolder.ServerRelativeUrl;
// This line of code is incorrect, so it returned the wrong data, thus building the folder path incorrectly.
//
var segments = url.Account.Split(new char[] { '/' }, StringSplitOptions.RemoveEmptyEntries);
var path = parent;
// This is the replacement line of code that fixed the issue.
//
var segments = url.Uri.LocalPath.Substring(parent.Length+1).Split(new char[] { '/' }, StringSplitOptions.RemoveEmptyEntries);
// as well, this line had to be removed since it was no longer needed
//
// finally, add folder of interest
//
subFolders.Add(url.Folder);
Ultimately the issue turned out be that the folder structure did not exist that I was attempting to create the file in. One or more segments in the path were missing.
So if you ever see this error, make sure you're the folder exists that you are adding the file to. If it isn't, you will certainly experience this error.
I need to create a simple program, which goes through a user-given directory on Sharepoint and finds all the folders which are older than 1 month and then it copies them to some local hard drive.
Perhaps it creates some log in a way that this folder was moved to.......
Thanks

I wrote this sample code which you can use to understand how it can be done, or you can just use it, because it seems to work fine.
class Program
{
static void Main(string[] args)
{
MoveFolders("your_web_url", "your_doclib_url");
}
public static void MoveFolders(string webUrl, string listUrl)
{
using (SPSite site = new SPSite(webUrl))
{
using (SPWeb web = site.OpenWeb())
{
SPList targetList = web.GetList(web.Url + "/" + listUrl);
MoveFolders(targetList.RootFolder, #"C:\test"); // path to your local storage folder
}
}
}
public static void MoveFolders(SPFolder targetFolder, string rootLocalPath)
{
string currentPath = Path.Combine(rootLocalPath, targetFolder.Name);
if (!Directory.Exists(currentPath))
Directory.CreateDirectory(currentPath);
DateTime lastModified = (DateTime)targetFolder.Properties["vti_timelastmodified"]; //folder last modified date
if (lastModified < DateTime.Today.AddMonths(-1))
SaveFolderLocal(targetFolder, currentPath);
foreach (SPFolder folder in targetFolder.SubFolders)
{
MoveFolders(folder, currentPath);
}
}
public static void SaveFolderLocal(SPFolder folder, string localStoragePath)
{
foreach (SPFile file in folder.Files)
{
var contents = file.OpenBinary();
using (FileStream fileStream = new FileStream(Path.Combine(localStoragePath, file.Name), FileMode.Create))
{
fileStream.Write(contents, 0, contents.Length);
}
}
}
}
This code will save your doclib folder structure locally with contents of any folder modified more than one month ago. Just be careful of using recursive MoveFolders method, because it can cause a StackOverflowException on libraries with very complex folder structure.
