There really is a first time for everything. you dont really learn everything the time you start working. It is through mistakes that you learn. I got "iText" now. will try it using that.

I am using VS 2010 and C#. I am trying to create a pdf file in web application.

I am trying to convert a dataset to pdf file. The pdf file is getting generated, but when i try to open the pdf, i am getting the error as "Adobe reader could not open "sample.pdf" because it is either not a supported file type or because the file has been damaged"

I have tried with "application/pdf" as well as "application/octet-stream". Both are giving the same error.

How to fix this?

Thank you

Thank you very much the reply.

Is there any solution you could suggest to correct that behavior.

Thank you

Thank you very much for the reply. I understand that I should have used WSPBuilder. I would download it and start working with it as you mentioned.

I checked the blog and changed code to below:

    public static class SpSecurityHelper
    {
        public static SPSite GetElevatedSite(SPSite theSite)
        {
            SPUserToken sysToken = GetSystemToken(theSite);
            return new SPSite(theSite.ID, sysToken);
        }

        public static SPUserToken GetSystemToken(SPSite site)
        {
            site.CatchAccessDeniedException = false;
            try
            {
                return site.SystemAccount.UserToken;
            }
            catch (UnauthorizedAccessException)
            {               
                SPUserToken sysToken = null;
            
                SPSecurity.RunWithElevatedPrivileges(
                delegate()
                {
                    using (SPSite lolcatKiller = new SPSite(site.ID))
                    {
                        sysToken = lolcatKiller.SystemAccount.UserToken;                    
                    }
                }
                );
                return sysToken;
            }
        }
    } 


  public class ItemCounting : SPItemEventReceiver
    {
        public override void ItemAdded(SPItemEventProperties properties)
        {
            base.ItemAdded(properties);
            GetOpenItems();
        }

public override void ItemDeleted(SPItemEventProperties properties)
        {
            base.ItemDeleted(properties);
            GetOpenItems();
        }


public static void GetOpenItems()
  {
using (SPSite site = SpSecurityHelper.GetElevatedSite(new SPSite(Constants.url)))
  {
using (SPWeb currentweb = site.OpenWeb())
  {
SPListCollection mylists = currentweb.GetListsOfType(SPBaseType.DocumentLibrary);
for (int q = mylists.Count - 1; q >= 0; q--)                           
{
SPList list = mylists[q];

if (!list.Hidden)
{                              
currentweb.AllowUnsafeUpdates = true;
SPFolder folder = list.RootFolder;
SPView curview = list.DefaultView;
SPViewFieldCollection fieldCol = curview.ViewFields;
if (!fieldCol.Exists("FilesCount"))
{
AddField("FilesCount", SPFieldType.Text, list.Fields);
fieldCol.View.DefaultView = true;                                      
curview.ViewFields.Add("FilesCount");
curview.Update();                                  
}
                                           
int jouas = 0;                              
if (folder != null && folder.Name.CompareTo("Forms") != 0)
{
   foreach (SPFolder subFolder in folder.SubFolders)
  {                                         
if (subFolder.Name.CompareTo("Forms") != 0)
    {
    jouas = GetItemsForFolderInt(subFolder);
   subFolder.Item["FilesCount"] = jouas;
   subFolder.Item.Update();    
}
}
}                              
  }
}               
}
}
}
}

The code is still running only for Admin account and not for other users. Any suggestions on this.

Thank you

I had created a feature and activated in the SharePoint site using the Admin account. The feature was to count the number of files under each sub folder. The feature got activated successfully. I tested the code under the Admin account, and it was working.
I tried to test with other users, who had design and contribute access. But when the other users checked, the count was not showing. No errors were generated. This is the code I have used.

 public static void GetOpenItems()
  {
using (SPSite site = new SPSite(Constants.url))
  {
using (SPWeb currentweb = site.OpenWeb())
  {
SPListCollection mylists = currentweb.GetListsOfType(SPBaseType.DocumentLibrary);
for (int q = mylists.Count - 1; q >= 0; q--)                           
{
SPList list = mylists[q];

if (!list.Hidden)
{                              
currentweb.AllowUnsafeUpdates = true;
SPFolder folder = list.RootFolder;
SPView curview = list.DefaultView;
SPViewFieldCollection fieldCol = curview.ViewFields;
if (!fieldCol.Exists("FilesCount"))
{
AddField("FilesCount", SPFieldType.Text, list.Fields);
fieldCol.View.DefaultView = true;                                      
curview.ViewFields.Add("FilesCount");
curview.Update();                                  
}
                                           
int jouas = 0;                              
if (folder != null && folder.Name.CompareTo("Forms") != 0)
{
   foreach (SPFolder subFolder in folder.SubFolders)
  {                                         
if (subFolder.Name.CompareTo("Forms") != 0)
    {
    jouas = GetItemsForFolderInt(subFolder);
   subFolder.Item["FilesCount"] = jouas;
   subFolder.Item.Update();    
}
}
}                              
  }
}               
}
}
}

These are the steps I used to install the feature from dev environment to Production environment.

1) Copied the dll from GAC and pasted in Production server's GAC.

2) Copied the relevant feature folders from 12 hive and pasted in the corresponding 12 hive of production server

3) Used the Stsadm Install and Activate commands for the site.

Is there anything else I should be doing?

Please help.. I am not sure, what to do. The feature is working only for Admin account and not for users having other permissions.

Thank you.

Sven, I can't help but read this thread with amusement. I think it's worth giving up, there's no hope for venkatzeus here; I get the impression he has absolutely zero hold on any of the concepts involved.

Hi,

I got the solution. One of the methods had a Url, which pointed to the pdf. I then used that with Process.start and invoked the pdf.

Thanks Sven Groot and all for the help.

What's a blob? I know what it is in database terms, but in C# terms it means nothing.

 

What's the .Net type, the class name, of the web method's return value?

In the webreference, when I add the reference, I get the following:

WebMethodName ( id As int ) As BLOB

Sven Groot said:

Using the BinaryFormatter.Serialize method doesn't just write out the raw data of the object. It adds all kinds of stuff to ensure that the data can be safely deserialized again, like .Net type names. So the result of this method will definitely not be a valid PDF file.

 

If the web service's return value indeed contains a PDF document in some format, you need to properly extract that data somehow. Without knowing the web services actual return type I can't help you with that. What is the type of the object returned by the web method?

The Web Method returns a blob

Sven Groot said:

venkatzeus said:

No, that's not what you're doing at all. You're creating a byte array, containing a serialized object graph (which is not valid PDF data), and then telling the browser to interpret that data as if it were a PDF.

 

You are creating a PDF file, but the contents you supply for that file (the serialized object graph) is not a valid PDF document, so of course Adobe Reader can't open it. There is no magic process that can convert a serialized object graph to a PDF.

 

What are you trying to do here exactly? What kind of data is that web service returning, and how is that data meant to be presented as a PDF?

Hi,

Thank you very much for the reply. Thanks for correcting me.

The web service returns a pdf file as a serialized data, which has the return type as blob.

Sven Groot said:

venkatzeus said:

*snip*

There is no way that serializing an object could yield a valid PDF. How were you expecting this to become a PDF?

I am converting to a byte array, and then using byte array to create a pdf.

W3bbo said:

You're not creating a PDF, you're just serving the raw bytes of a PDF to the client.

 

Where are you getting your bytes from?

Hi,

Thank you very much for the reply.

I am converting a serilaized data,which i recieve from a web service to a byte array.

I am missing anything. Thank you

I am using C#. I am trying to create a pdf file from byte array.

I tried the below code in the page load. The variable blob contains the byte array data.

 
Response.Clear(); 
Response.AddHeader("Content-Length", blob.Length.ToString()); 
Response.ContentType = "application/pdf"; 
Response.AddHeader("Accept-Ranges", "bytes"); 
Response.Buffer = true; 
Response.AddHeader("Expires", "0"); 
Response.AddHeader("Cache-Control", "must-revalidate, post-check=0, pre-check=0"); 
Response.AddHeader("Pragma", "public"); 
Response.AddHeader("content-Transfer-Encoding", "binary"); 
Response.AddHeader("Content-Disposition", "attachment; filename=sample.pdf"); 
Response.BinaryWrite(blob); 
Response.Flush(); 
Response.End();

The pdf is getting saved. But when I try to open the pdf, I am getting the error as " Acrobat could not open 'sample.pdf' because it is either not a supported file type or because the file has been damaged"

How to create a pdf file from a byte array?

Thank you

I am using ASP.NET 2.0 and C#.  I am not using AJAX.

I have added an Adrotator in my page. I want to refresh the adrotator after every ten seconds. Currently when the adrotator refreshes, the page is also getting refreshed.

How to refresh the adrotator without refreshing the complete page and not using Ajax?

That folder should be a subdirectory of your website, not a random directory on your server. IIS is not configured to serve files from that directory.

Thank you very much for the reply.

I got it.

The mailto: command is very useful,  but not so useful when a large chunk of HTML formatted body text must also be sent.

I want my application to to create a full new mail message (in the default mail client, usually Outlook), which the user can then modify and send. Specifying mailto: someid ?body=XXX  will not suffice, as the body text is too long and must be HTML formatted.

Is there any alernate to using the mailto command.

Thank you

W3bbo said:

It seems to me as though you've neglected the first step of web-application debugging: looking at the generated HTML sent to the browser.

 

If you do, you'll see that your script is sending absolute file paths to the client. You should be sending paths relative to the current script URL.

Hi,

Thank you very much for the reply.

The Images are available in the server's (D:\Newfolder) path.

How to convert this absolute path to a relative path in ASP and send.

Could you please help me in this.

Thank you

I am using classic ASP. I have few images in my folder, which is inside the wwwroot of the server. I am trying to display the images in a ASP page. Below is the code i have used.

<% Option Explicit %> 
<html> <head> <title>Untitled</title> </head> 
<body> 
<form action="<%= Request.ServerVariables("SCRIPT_NAME") %>" method="post">
 <input type="text" name="directory" value="D:\NewFolder\"/> 
<input type="submit"> 
</form> 
<% 
Dim strPath, fso, fsoFolder, fsoFile, i 
If Request.Form("directory") <> "" Then
 strPath = Request.Form("directory") 
If Not Right(strPath, 1) = "\" Then 
strPath = strPath & "\" 
End If 
Set fso = Server.CreateObject("Scripting.FileSystemObject") 
If fso.FolderExists(strPath) = True Then 
Set fsoFolder = fso.GetFolder(strPath) 
i = 1 
For Each fsoFile In fsoFolder.Files 
If UCase(fso.GetExtensionName(fsoFile.Name)) = "JPG" Or 
_ UCase(fso.GetExtensionName(fsoFile.Name)) = "GIF" Then 
i = i + 1 
Response.Write "<img src=""" & strPath & fsoFile.Name & """ height=""80"" border=""0"" alt=""" & fsoFile.Name & """>" 
 
If i = 10 Then Response.Write "<br>" 
End If 
Next 
Else 
Response.Write("Folder " & strPath & " does not exist.") 
End If 
Set fso=nothing 
Set fsoFolder=nothing 
End If 
%> 
</body> </html>

The images are existing in the computer itself. In the output, i am getting the broken image icon only.

The "mailto:" URI-scheme supports parameters.

 

Like so:

 

mailto:someone@somecompany.com?subject=Subject goes here&cc=CC addresses go here

 

Addresses must be comma-separated. See this page for a reference.

Hi,

Thank you very much. It helped.

I have a mail in Outlook 2007, which has a link in it. When the user clicks on the link, i want to open another mail with predefined To address, cc address, subject and content.

How to open a new mail with the above details, when user clicks on the link in the mail he receives?

Thank you

I have a asp page, which is used to send e-mail. In the mail, I have a link to open a document, which is in a webpage.

The user gets the email in mail box(outlook 2007/webmail) . When the user clicks on the link in the mail, i want to fetch the username and password of the user and then send it to web application by which the user can be logged in and display(open) the document.

How to achieve this?

Thank you.

What are you using to query the XML? XPath, LINQ to XML (C# or VB?), something else?

With XPath it would be something like this:
1) /aname/an[@alname="George"]
2) /aname/an[starts-with(@alname, "G")]
3) /aname/an[contains(@alname, "e")]

Note that making the queries case-insensitive would be very awkward with XPath; LINQ to XML would be much easier there.

EDIT: Ninja'd by joechung.

Hi,
Thank you very much for the reply..
I am using XPath to query.

I was struck with wild card searching, so had posted it here..
