Hi
I wrote a webForm that is used to display a ".pdf" document receiving from one other webForm the path of the file by queryString.
The all is working well but if from acrobat reader somebody try to save the file in local on openDialog is displayed the name of webForm ("PopVisPdf.pdf").
the question is:
How can display the real name of file in this situation ?
the code of webForm that I use:
protected void Page_Load(object sender, EventArgs e)
{
CryptoString Uncrypt = new CryptoString();
string id = Request.QueryString["Id"];
string pathPdf = Uncrypt.DecryptString(id);
Response.ContentType = "application/pdf";
Response.TransmitFile(pathPdf);
Response.End();
}
Thankyou in advance for helping
Piercarlo
I resolved from myself.
well only need to call the winform that show the file with this string:
http://MyForm.aspx/FileName.pdf?id=.........
where "FileName.pdf is the name that I want to give
Is working beatifull
Hope that can be usefull to somebody else.
Regards

I am using the local database example taht Microsoft created.
I can add items to the list, and delete them. But I now want to select the items and get the text of the item and use that in the next page.
This is the select changed event:
private void allToDoItemsListBox_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
NavigationService.Navigate(new Uri("/LiveTimes.xaml?selectedItem=" + allToDoItemsListBox.SelectedIndex, UriKind.Relative));
// string urlWIthData = string.Format("/LiveTimes.xaml?name={0}", " ");
// this.NavigationService.Navigate(new Uri(urlWIthData, UriKind.Relative));
}
Then this is the on page load on the other page.
string selectedIndex = "";
if (NavigationContext.QueryString.TryGetValue("selectedItem", out selectedIndex))
{
int index = int.Parse(selectedIndex);
DataContext = App.ViewModel.HomeToDoItems[index];
}
Then when i use this, the error is on the DataContext line.
Whats the solution?
There is no problem in the above code that you have shown, The actual problem may be in the way how you defined your ViewModel and HomeToDoItems . It helps us to solve your problem, if you can show some of that code.
Also before setting your data to DataContext, try the following steps:
First, make sure you are getting the valid selectedIndex.
var tempData = App.ViewModel.HomeToDoItems[index];
DataContext = tempData;
And then insert a break point at tempData to check whether you are getting the expected data.
This answer may not solve your problem, but guide you in identifying the actual problem.
i want to get the time schedule on
http://www.21cineplex.com/playnow/sherlock-holmes-a-game-of-shadows,2709.htm
first,
i have tried using webclient with htmlAgilityPack and get to the table id = "table-theater" but appearently the html generated from java script so the table innetHTML is empty.
public void LoadMovieShowTime(string MovieLink)
{
WebClient MovieShowTimeclient = new WebClient();
MovieShowTimeclient.DownloadStringAsync(new Uri(MovieLink));
MovieShowTimeclient.DownloadStringCompleted += new DownloadStringCompletedEventHandler(MovieShowTimeclient_DownloadStringCompleted);
}
void MovieShowTimeclient_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
{
HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(e.Result);
var node = doc.DocumentNode.Descendants("div").First()
.Elements("div").Skip(1).First()
.Elements("div").Skip(1).First()
.Element("div")
.Elements("table").FirstOrDefault(table => table.Attributes["class"].Value == "table-theater");
}
Is it possible to get the data using webclient on windows phone? or is there any pssible way to get it using another method?
second,
i have tried to get the time schedule from mobile site which is
http://m.21cineplex.com/gui.list_schedule?sid=&movie_id=11SHGO&find_by=1&order=1
but the return ask me to enable cookies. im new to this, i find that there is a way to extend webclien ability by overriding the webRequest cookies, but cant find any reference how to use it.
thanks, for any reply and help :)
Just because the table is generated in JavaScript does not mean the WebBrowser control will not render it. Ensure that IsScriptEnabled is set to true, this will ensure that the JavaScript that renders the table is executed. You can then 'scrape' the results.
I am using the Background Transfer to upload Photographs to my Web Service. As the Photograph uploads can consume significant time and memory, I thought it might be a nice idea to use the background transfer request to accomplish this. After the photo is uploaded, I want to obtain the Id of the uploaded photo and then use it for post-processing. However, it turns out I can't do that in a background transfer request.
Per my understanding, Background Transfer works using the following logic ONLY:
You have to obtain the file you want to upload and then save/copy it to your app's Isolated Storage under the folder: shared/transfers. This is extremely important. Apparently, using file in a different location didn't work for me. Maybe it isn't the shared/transfers as much as it is a 'relative' path. But I would stick to the same conventions.
After you have saved the file in that location, your background request can be created based on that. It doesn't look like you can pass POST CONTENT other than the file contents, so any other parameters like file name, mime type etc. will need to be passed as QUERY String parameters only. I can understand this, but it would've been nice if I could pass both as POST Content. I don't think HTTP has a limitation on how this works.
Here is some code for creating a request using Hammock:
string url = App.ZineServiceAuthority + "articles/save-blob?ContainerName={0}&MimeType={1}&ZineId={2}&Notes={3}&IsPrivate={4}&FileName={5}";
url = String.Format(url, userId, "image/jpg", ZineId, txtStatus.Text, true, UploadFileName);
var btr = new BackgroundTransferRequest(new Uri(url, UriKind.Absolute));
btr.TransferPreferences = TransferPreferences.AllowCellularAndBattery;
btr.Method = "POST";
btr.Headers.Add("token", IsolatedStorageHelper.GetTravzineToken());
btr.UploadLocation = new Uri(#"/shared\transfers/" + UploadFileName, UriKind.Relative);
btr.TransferStatusChanged += new EventHandler<BackgroundTransferEventArgs>(btr_TransferStatusChanged);
btr.TransferProgressChanged += new EventHandler<BackgroundTransferEventArgs>(btr_TransferProgressChanged);
BackgroundTransferService.Add(btr);
In my case, I am literally passing all the necessary parameters using the query string. On a successful save, my Web Service returns back the Id of the Photo I just uploaded. However:
There is NO way (or at least I know of) to obtain and evaluate the RESPONSE. The Background Transfer Request Event handlers do not expose a RESPONSE.
Here are my event handlers:
void btr_TransferProgressChanged(object sender, BackgroundTransferEventArgs e)
{
bool isUploading = e.Request.TotalBytesToSend > 0 ? true : false;
lblStatus.Text = isUploading ? "Uploading" + e.Request.BytesSent.ToString() + " sent" : "Done";
}
void btr_TransferStatusChanged(object sender, BackgroundTransferEventArgs e)
{
if (e.Request.TransferStatus == TransferStatus.Completed)
{
using (IsolatedStorageFile iso =
IsolatedStorageFile.GetUserStoreForApplication())
{
if (iso.FileExists(e.Request.UploadLocation.OriginalString))
iso.DeleteFile(e.Request.UploadLocation.OriginalString);
}
BackgroundTransferService.Remove(e.Request);
if (null != e.Request.TransferError)
{
MessageBox.Show(e.Request.TransferError.Message);
}
else
{
lblStatus.Text = "Done baby done";
}
}
}
So now my question is, how does anyone do any sort of POST Processing in such scenarios?
Can anyone please tell me the line of thought behind designing such an inflexible class?
Any thoughts on how I could get around this issue would be appreciated.
Also, does anyone have any working examples of a homegrown BackgroundTransfer?
Haven't tried it but why not set a download location like this:
btr.DownloadLocation = "myDownloadFile.html";
btr.UploadLocation = "myUploadFile.jpg";
...
If the request is completed read the file "myDownloadFile.html" where your response has been stored and delete it afterwards.
I am using Sap Crystal Report in asp.net 2010
It will shows the error no valid report source id available, when i refreshing the report or moving to next page at run time using report viewer tools
and this is my coding,
Dim crdoc5 As New ReportDocument()
Dim crtablogoninfo5 As New TableLogOnInfo
Dim crtabs5 As Tables
If Not IsPostBack Then
crdoc5.Load(Server.MapPath("CrStaffrecruit.rpt"))
Session.Add("CrStaffrecruit", crdoc5)
CrystalReportViewer5.ReportSource = crdoc5
Else
CrystalReportViewer5.ReportSource = Session("CrStaffrecruit")
End If
crdoc5.Load(Server.MapPath("CrStaffrecruit.rpt"))
Dim crconninfo5 As New ConnectionInfo()
rconninfo5.ServerName = "servername"
crconninfo5.DatabaseName = "databasename"
crconninfo5.UserID = "sa"
crconninfo5.Password = ""
crtabs5 = crdoc5.Database.Tables()
For Each crtab5 As CrystalDecisions.CrystalReports.Engine.Table In crtabs5
crtablogoninfo5 = crtab5.LogOnInfo
crtablogoninfo5.ConnectionInfo = crconninfo5
crtab5.ApplyLogOnInfo(crtablogoninfo5)
Next
CrystalReportViewer5.ReportSource = crdoc5
CrystalReportViewer5.RefreshReport()
If any one know pls help me...
Thanks in advance

Although the following code is in C#, it shouldn't be too difficult to translate it to VB and it should solve your issue:
protected void Page_Load(object sender, EventArgs e)
{
if (Page.IsPostBack)
{
//whatever you do when the page is loaded for the first time
//this could even be bindReport();
}
else
{
bindReport();
}
}
public void bindReport()
{
ReportDocument rptDoc = new ReportDocument();
dsSample ds = new dsSample(); // .xsd file name
DataTable dt = new DataTable();
// Just set the name of data table
dt.TableName = "Crystal Report Example";
dt = getMostDialledNumbers(); //This function populates the DataTable
ds.Tables[0].Merge(dt, true, MissingSchemaAction.Ignore);
// Your .rpt file path will be below
rptDoc.Load(Server.MapPath("yourReportFilePath.rpt"));
//set dataset to the report viewer.
rptDoc.SetDataSource(ds);
CrystalReportViewer1.ReportSource = rptDoc;
CrystalReportViewer1.RefreshReport();
//in case you have an UpdatePanel in your page, it needs to be updated
UpdatePanel1.Update();
}
I was experiencing the same problem. In what event are you executing the code you posted? I ask because after much debugging, I discovered that you need to place the code in Page_Load (as opposed to PreRender like I was doing previously...)
Hope this helps.
I have got this problem several times, and the solution is to save the Report Document variable in a session then in the Page_load put the below code:
if (IsPostBack)
{
if (Session["reportDocument"] != null)
{
ReportDocument cr = new ReportDocument();
cr = (ReportDocument)Session["reportDocument"];
CrystalReportViewer1.ReportSource = cr;
CrystalReportViewer1.DataBind();
}
}
NB:
Don't forget to fill the (Session["reportDocument"]) with the Display button.
Go through following link. I resolved same issue with that solution.

I'm having a problem using Winnovatives PDFConverter on pages that are protected by Extranet security (which is based on ASP.Net Membership).
I've tried several different approaches, but the following I can get to work on my local machine, but not anywhere else.
Code for login page, this code should bypass the login process for:
// check that the current "user" isn't logged in and is the Winnovative UserAgent
if (!Sitecore.Context.IsLoggedIn && Request.UserAgent.Contains(".NET CLR"))
{
//Login with a dummy user I've created
Sitecore.Security.Authentication.AuthenticationManager.Login("extranet\\pdf", "pdf", true);
//redirect to former page
}
The page that generates the PDF uses this code:
private void PDFPrint(string url)
{
PdfConverter pdfConverter = new PdfConverter();
pdfConverter.LicenseKey = "our license";
url = Request.Url.Scheme + "://" + Request.Url.Host + url;
byte[] downloadBytes = pdfConverter.GetPdfFromUrlBytes(url);
HttpResponse response = HttpContext.Current.Response;
response.Clear();
response.AddHeader("Content-Type", "binary/octet-stream");
response.AddHeader("Content-Disposition", "attachment; filename=" + Sitecore.Context.Item.Name + ".pdf" + "; size=" + downloadBytes.Length.ToString());
response.Flush();
response.BinaryWrite(downloadBytes);
response.Flush();
response.End();
}
The Exception I'm getting is this:
"Could not get the metafile from url. Could not get image from url.The URL is not accessible.."
I've also tried this trick from the Winnovative FAQ to no avail:
http://www.winnovative-software.com/FAQ.aspx#authenticationQ
I've also tried to use WebClient or HttpWebRequest to retrieve the content.
But nothing I do seems to work other than locally.
Basically I want to create a way of either getting Winnovatives converter to use the current logged in user, my custom "pdf" user og some other way of getting the html from the response.
I hope this question isn't too vague, but I find it kinda hard to ask. But basically I want to get some html content from a page on a Sitecore solution I control, which is protected by Sitecore normal Extranet security. This html content should be in string or byte[] format.
Help me Stackoverflowers, you're my only hope! :P
I contacted Sitecore to ask if they had a solution.
Their solution was to create a Processor that would set an active user based on some criteria.
This is the code I made for my site (it's probably not the best solution as UserAgent can be spoofed):
public class MyResolver : HttpRequestProcessor
{
// Methods
public override void Process(HttpRequestArgs args)
{
var userAgent = args.Context.Request.UserAgent ?? "";
SiteContext site = Sitecore.Context.Site;
if (site.Name == "site_name_in_webconfig" && userAgent.Contains("this_should_only_be_in_thepdfcreators_userAgent"))
{
Sitecore.Security.Accounts.User pdfuser = Sitecore.Security.Accounts.User.FromName("extranet\\theUser", true);
AuthenticationManager.SetActiveUser(pdfuser);
}
}
}
and then add the following to the web.config, before the UserResolver:
<processor type="Namespace.MyResolver, Assembly" />
I hope this will help some others out there.
I've found a similar issue on the ASP.NET forums and the answer to that was to use a newer version of the PDF tool: SessionState Problems ?
