I have used TempData to pass data between controllers. If two users are working on the same page, User2 will get the tempdata value which is created by User1.
Below you can find the code.
Can you please help me to solve this issue.
VDRController.cs
public ActionResult RedirectToCDR(long VslMoveId, long VslVisitId, string VslNm, string ETDDtTmLoc, string statusCd)
{
//List<long> vslIds = new List<long>();
string vslIds = VslMoveId + "," + VslVisitId.ToString() + "," + statusCd;
TempData["VslMoveDetails"] = vslIds;
//DateTime MyDateTime;
//MyDateTime = new DateTime();
var strdatetime = Convert.ToDateTime(ETDDtTmLoc).ToString("dd-MMM-yyyy");
TempData["VslNameETD"] = VslNm + " " + strdatetime;
//return RedirectToAction("Index","VesselVisit");
return Json(Url.Action("Index", "CDR"));
}
CDRController.cs
public ActionResult Index()
{
if (TempData["VslMoveDetails"] != null)
{
string vslIds = TempData["VslMoveDetails"].ToString();
string[] Ids = vslIds.Split(new char[] { ',' });
if (Ids.Length == 3 && Ids[0] != null && Ids[1] != null)
{
ViewBag.VslMove_Id = Ids[0];
ViewBag.VslVisit_Id = Ids[1];
ViewBag.VisitStatus_Cd = Ids[2];
}
}
return View();
}
thanks in advance.
Your pages are being cached by IIS. For MVC applications you will need to add .cshtml to the list of file extensions that are not allowed to cache. Please see the following link for the solution to stop caching. (http://lionsden.co.il/codeden/?p=446)

I have two action methods in my Controller class:
DetailsAll: to get some data and display in the view
SaveAsPDF: Called on windows.load of DetailsAll.cshtml which should save DetailsAll view as pdf
My issue is in SaveAsPDF Action method. Here I am trying to use Rotativa ActionAsPdf and subsequently BuildFile methods to generate and save the PDF. However, when executing the line "BuildFile", it is not hitting the breakpoint in my DetailsAll Action method, subsequently causing the PDF to be generated blank.
Could you please help where I am going wrong?
[HttpGet]
public ActionResult DetailsAll()
{
var selectionBuilder = builderFactory.GetGeocodeReportSelectionViewModelBuilder();
var companyList = selectionBuilder.Build();
List<GeocodeReportViewModel> viewModel = new List<GeocodeReportViewModel>();
foreach(SelectListItem record in companyList.Companies)
{
var builder = builderFactory.GetGeocodeReportViewModelBuilder(int.Parse(record.Value));
viewModel.Add(builder.Build());
}
var model = new AllGeocodeReportViewModel
{
GeocodeReports = viewModel
};
return View(model);
}
[HttpGet]
public string SaveAsPDF()
{
var report = new ActionAsPdf("DetailsAll")
{
FileName = "OEM_GeocodeReport_" + System.DateTime.Now.ToString("MMYY") + ".pdf",
PageSize = Size.A4,
PageOrientation = Orientation.Landscape,
PageMargins = { Left = 1, Right = 1 }
};
byte[] pdf = report.BuildFile(ControllerContext);
System.IO.File.WriteAllBytes("C:\\" + report.FileName, pdf);
return "true";
}
Finally found the issue after extensive search. I need to send Authentication cookies along with the BuildFile request for this to work. Added the below code and it generates PDF correctly now:
public void SaveAsPDF()
{
var cookies = Request.Cookies.AllKeys.ToDictionary(k => k, k => Request.Cookies[k].Value);
var report = new ActionAsPdf("DetailsAll")
{
FileName = "OEM_GeocodeReport_" + System.DateTime.Now.ToString("MMyy") + ".pdf",
PageSize = Size.A4,
PageOrientation = Orientation.Portrait,
PageMargins = { Left = 3, Right = 3 },
FormsAuthenticationCookieName = System.Web.Security.FormsAuthentication.FormsCookieName,
Cookies = cookies
};
byte[] pdf = report.BuildFile(ControllerContext);
System.IO.File.WriteAllBytes("C:\\" + report.FileName, pdf);
}
I have a ldap method that returns all users that are in it (almost 1300 users) and I want to return them by page, similar to what PagingAndSortingRepository does in Springboot:
If I have this endpoint ( users/?page=0&size=1 )and I wnat to return on page 0 just 1 entry.
Is there any way to do that?
Currently I have this but it doesn´t work:
SearchRequest searchRequest = new SearchRequest(ldapConfig.getBaseDn(), SearchScope.SUB,
Filter.createEqualityFilter("objectClass", "person"));
ASN1OctetString resumeCookie = null;
while (true) {
searchRequest.setControls(new SimplePagedResultsControl(pageable.getPageSize(), resumeCookie));
SearchResult searchResult = ldapConnection.search(searchRequest);
numSearches++;
totalEntriesReturned += searchResult.getEntryCount();
for (SearchResultEntry e : searchResult.getSearchEntries()) {
String[] completeDN = UaaUtils.searchCnInDn(e.getDN());
String[] username = completeDN[0].split("=");
UserEntity u = new UserEntity(username[1]);
list.add(u);
System.out.println("TESTE");
}
SimplePagedResultsControl responseControl = SimplePagedResultsControl.get(searchResult);
if (responseControl.moreResultsToReturn()) {
// The resume cookie can be included in the simple paged results
// control included in the next search to get the next page of results.
System.out.println("Antes "+resumeCookie);
resumeCookie = responseControl.getCookie();
System.out.println("Depois "+resumeCookie);
} else {
break;
}
Page<UserEntity> newPage = new PageImpl<>(list, pageable, totalEntriesReturned);
System.out.println("content " + newPage.getContent());
System.out.println("total elements " + newPage.getTotalElements());
System.out.println(totalEntriesReturned);
}
I'm unsure if this is the proper way, but here's how I went about it:
public PaginatedLookup getAll(String page, String perPage) {
PagedResultsCookie cookie = null;
List<LdapUser> results;
try {
if ( page != null ) {
cookie = new PagedResultsCookie(Hex.decode(page));
} // end if
Integer pageSize = perPage != null ? Integer.parseInt(perPage) : PROCESSOR_PAGE_SIZE;
PagedResultsDirContextProcessor processor = new PagedResultsDirContextProcessor(pageSize, cookie);
LdapName base = LdapUtils.emptyLdapName();
SearchControls sc = new SearchControls();
sc.setSearchScope(SearchControls.SUBTREE_SCOPE);
sc.setTimeLimit(THREE_SECONDS);
sc.setCountLimit(pageSize);
sc.setReturningAttributes(new String[]{"cn", "title"});
results = ldapTemplate.search(base, filter.encode(), sc, new PersonAttributesMapper(), processor);
cookie = processor.getCookie();
} catch ( Exception e ) {
log.error(e.getMessage());
return null;
} // end try-catch
String nextPage = null;
if ( cookie != null && cookie.getCookie() != null ) {
nextPage = new String(Hex.encode(cookie.getCookie()));
} // end if
return new PaginatedLookup(nextPage, results);
}
The main issue I kept on hitting was trying to get the cookie as something that could be sent to the client, which is where my Hex.decode and Hex.encode came in handy.
PersonAttributesMapper is a private mapper that I have to make the fields more human readable, and PaginatedLookup is a custom class I use for API responses.
I'm trying to use the built in upload file of CKEditor, it works with my MVC5 project, but it doesn't work with my MVC6 project, the code for uploading the file is correct, I've tested it, and it actually upload the file to the server, but it doesn't populate the form with the URL and image information, here's the code for my MVC5 project that works:
public ActionResult UploadImage(HttpPostedFileBase upload, string CKEditorFuncNum, string CKEditor,
string langCode)
{
string vImagePath = String.Empty;
string vMessage = String.Empty;
string vFilePath = String.Empty;
string vOutput = String.Empty;
try
{
if (upload != null && upload.ContentLength > 0)
{
var vFileName = DateTime.Now.ToString("yyyyMMdd-HHMMssff") + " - " + Path.GetFileName(upload.FileName);
var vFolderPath = Server.MapPath("/Upload/");
if (!Directory.Exists(vFolderPath))
{
Directory.CreateDirectory(vFolderPath);
}
vFilePath = Path.Combine(vFolderPath, vFileName);
upload.SaveAs(vFilePath);
vImagePath = Url.Content("/Upload/" + vFileName);
vMessage = "The file uploaded successfully.";
}
}
catch(Exception e)
{
vMessage = "There was an issue uploading:" + e.Message;
}
vOutput = #"<html><body><script>window.parent.CKEDITOR.tools.callFunction(" + CKEditorFuncNum + ", \"" + vImagePath + "\", \"" + vMessage + "\");</script></body></html>";
return Content(vOutput);
}
And here is the code for MVC6 project that doesn't work:
public async Task<ActionResult> UploadImage(IFormFile upload, string CKEditorFuncNum, string CKEditor,
string langCode)
{
string vImagePath = String.Empty;
string vMessage = String.Empty;
string vFilePath = String.Empty;
string vOutput = String.Empty;
try
{
if (upload != null && upload.Length > 0)
{
var vFileName = DateTime.Now.ToString("yyyyMMdd-HHMMssff") + " - " + ContentDispositionHeaderValue.Parse(upload.ContentDisposition).FileName.Trim('"');
var vFolderPath = Path.Combine(_environment.WebRootPath, "Files", "ArticleUploads");
if (!Directory.Exists(vFolderPath))
{
Directory.CreateDirectory(vFolderPath);
}
vFilePath = Path.Combine(vFolderPath, vFileName);
await upload.SaveAsAsync(vFilePath);
vImagePath = Url.Content("/Files/ArticleUploads/" + vFileName);
vMessage = "The file uploaded successfully.";
}
}
catch (Exception e)
{
vMessage = "There was an issue uploading:" + e.Message;
}
vOutput = #"<html><body><script>window.parent.CKEDITOR.tools.callFunction(" + CKEditorFuncNum + ", \"" + vImagePath + "\", \"" + vMessage + "\");</script></body></html>";
return Content(vOutput);
}
And in CKEditor config file I have:
config.filebrowserImageUploadUrl = '/Admin/Article/UploadImage';
I've inspected the variables, and they send the same value, also worth to note that I'm using the same version of CKEditor, so that can't be the problem, I'd appreciate any help on this.
If the file gets uploaded and you don't see the image gets populated, I guess there should be some problem with the way you return your content, since you are returning html, try to specify your content type, like so:
return Content(vOutput, "text/html");
If that didn't solve your problem, you need to provide more information, tell us what exactly you get from this action in JavaScript side.
Im trying to use a .net application but the application cant find the server in my local network.
Im using LdapExploreTool 2 with the following settings:

How can i establish a connection?
The problem was the LDAP connection string,
it seems that it missed the actual location(IP + port) in the network.
LDAP://192.168.1.250:389/DC=exago,DC=local
I am using EWS and wish to obtain the global address list from exchange for the company. I know how to retrieve the personal contact list.
All the samples in the API documentation deal with updating user information but not specifically how to retrieve them.
I've even tried the following to list the folders but it doesn't yeild the correct results.
private static void ListFolder(ExchangeService svc, FolderId parent, int depth) {
string s;
foreach (var v in svc.FindFolders(parent, new FolderView(int.MaxValue))) {
Folder f = v as Folder;
if (f != null) {
s = String.Format("[{0}]", f.DisplayName);
Console.WriteLine(s.PadLeft(s.Length + (depth * 2)));
ListFolder(svc, f.Id, depth + 1);
try {
foreach (Item i in f.FindItems(new ItemView(20))) {
Console.WriteLine(
i.Subject.PadLeft(i.Subject.Length + ((depth + 1) * 2)));
}
} catch (Exception) {
}
}
}
}
While the question has already been raised (How to get contact list from Exchange Server?) this question deals specifically with using EWS to get the global address list while this question asks for advice on a general level.
you may got ItemType objects in a specifiedfolder with the code snippet below
and then cast ItemType objects to ContactItemType (for contact objects) ....
/// <summary>
/// gets list of ItemType objects with maxreturncriteria specicification
/// </summary>
/// <param name="esb">ExchangeServiceBinding object</param>
/// <param name="folder">FolderIdType to get items inside</param>
/// <param name="maxEntriesReturned">the max count of items to return</param>
public static List<ItemType> FindItems(ExchangeServiceBinding esb, FolderIdType folder, int maxEntriesReturned)
{
List<ItemType> returnItems = new List<ItemType>();
// Form the FindItem request
FindItemType request = new FindItemType();
request.Traversal = ItemQueryTraversalType.Shallow;
request.ItemShape = new ItemResponseShapeType();
request.ItemShape.BaseShape = DefaultShapeNamesType.AllProperties;
request.ParentFolderIds = new FolderIdType[] { folder };
IndexedPageViewType indexedPageView = new IndexedPageViewType();
indexedPageView.BasePoint = IndexBasePointType.Beginning;
indexedPageView.Offset = 0;
indexedPageView.MaxEntriesReturned = 100;
indexedPageView.MaxEntriesReturnedSpecified = true;
request.Item = indexedPageView;
FindItemResponseType response = esb.FindItem(request);
foreach (FindItemResponseMessageType firmtMessage in response.ResponseMessages.Items)
{
if (firmtMessage.ResponseClass == ResponseClassType.Success)
{
if (firmtMessage.RootFolder.TotalItemsInView > 0)
foreach (ItemType item in ((ArrayOfRealItemsType)firmtMessage.RootFolder.Item).Items)
returnItems.Add(item);
//Console.WriteLine(item.GetType().Name + ": " + item.Subject + ", " + item.DateTimeReceived.Date.ToString("dd/MM/yyyy"));
}
else
{
//handle error log here
}
}
return returnItems;
}
I just did a similiar thing. However, I was unable to get the list of contacts via Exchange since that only gets users that have mailboxes, and not necessarily all users or groups. I eventually ended up getting all the users via AD
here is code to get all the contacts in AD. All you need is the folderID of the global address list which can be gotten from using the ADSI.msc tool on your AD server and browsing to the Global address list folder, look at properties and grab the value of the "purported search". In my system the searchPath for the global address list is"(&(objectClass=user)(objectCategory=person)(mailNickname=)(msExchHomeServerName=))"
public List<ListItem> SearchAD(string keyword, XmlDocument valueXml)
{
List<ListItem> ewsItems = new List<ListItem>();
using (DirectoryEntry ad = Utils.GetNewDirectoryEntry("LDAP://yourdomain.com"))

using (DirectorySearcher searcher = new DirectorySearcher(ad))
{
if (this.EnableSizeLimit)
{
searcher.SizeLimit = GetMaxResultCount();
if (Utils.maxResultsCount > 1000)
{
searcher.PageSize = 100;
}
}
else
{
searcher.SizeLimit = 1000;
searcher.PageSize = 10;
}
string sisya = Utils.DecodeXml(valueXml.SelectSingleNode("Folder/SearchPath").InnerText); //this is the folder to grab your contacts from. In your case Global Address list
//Container
if(String.IsNullOrEmpty(sisya))
{
return null;
}
keyword = Utils.EncodeLdap(keyword);
string text = Utils.DecodeXml(valueXml.SelectSingleNode("Folder/Text").InnerText);
searcher.Filter = this.CreateFilter(keyword, sisya);
searcher.Sort = new SortOption("DisplayName", System.DirectoryServices.SortDirection.Ascending);
//一つのPropertyをロードすると、全Propertyを取らないようになる
searcher.PropertiesToLoad.Add("SAMAccountName"); //どのPropertyでもいい。
