I'm working on a web app and need to stream various files. I can do pdfs, images, and older Office documents. However, when I try to do with 2007 documents, it breaks. Here is my code:
Response.Buffer = true;
Response.Clear();
Response.ClearContent();
Response.ClearHeaders();
switch (FileExtension.ToLower())
{
case "pdf":
Response.ContentType = "application/pdf";
break;
case "doc":
Response.ContentType = "application/msword";
break;
case "docx":
Response.ContentType = "application/vnd.ms-word.document.12";
break;
case "xls":
Response.ContentType = "application/vnd.ms-excel";
break;
case "xlsx":
Response.ContentType = "application/vnd.ms-excel.12";
break;
default:
Response.ContentType = "image/jpeg";
break;
}
Response.BinaryWrite(buffer);
The error that I get is:
An invalid character was found in text content. Error processing resource 'http://DomainName/GetFile.aspx.

I am loading documents into our Oracle database and then retrieving them for the users to view. So far PDF, DOC, XLS, CSV, etc. all perform as expected, however; DOCX, XLSX, etc. files have one annoyingly persistent issue. When the document is downloaded by the user and they open it you get the first in a series of messages: The file 'thefile.docx' cannot be opened because there are problems with the contents. Details: The file is corrupt and cannot be opened. and then: Word found unreadable content in 'thefile.docx'. Do you want to recover the contents of this document? If you trust the source, click Yes. After clicking yes the file opens and all of the content appears correct. Including images, formatting, tracked changeds and comments, equations, etc. I have tried multiple methods along these lines to no avail. I simply want the files to open without the false-positive error messages. I am using VS2010, with the website targeted at .Net Framework 2.0.
objConn =
New
OracleConnection(gstrConnectionString)
objConn.Open()
cmd = New

cmd.Connection = objConn
cmd.CommandText = "select DOCUMENT_NAME,DOCUMENT_TYPE,DOCUMENT
from DOCUMENT_TABLE where DOCUMENT_ID='"
& strDocumentID & "'"
dr = cmd.ExecuteReader

I have designed a report in RDLC. I am using Visual Studio 2008 and C#. Below is my code to export the report in excel. It always export the report to xls format which is Excel 2003. Excel 2003 has limited rows upto 65000. When i get rows more than 65000 for example 90000 then the export fails. Excel 2007 has power to handle more than 1000000 rows. I want to export the RDLC report to Excel 2007 to overcome the issue. how by modifying the following code i can export the report to Excel 2007.
byte[] bytes = null;
bytes = viewer.LocalReport.Render("Excel", null, out mimeType, out encoding, out extension, out streamIds, out warnings);
Response.Buffer = true;
Response.Clear();
Response.ContentType = mimeType;
Response.AddHeader("content-disposition", "attachment; filename=Rendered Services." + extension);
Response.BinaryWrite(bytes);
Response.Flush();

I have a web application (ASP.NET 3.5) that allows the users to upload their own excel sheet. This sheet contains information about items that needs to be inserted to SQL Server 2005.
I already have this functionality, however, it's very slow (it takes almost 20 minutes to finish the request). I need a better way to handle this problem.
The sheet contains information about an item. These properties will be inserted into multiple tables for example (Books, Authors, Titles ... etc ...).
What I'm currently doing is the following:
The user uploads the file. The application opens the file. Read each row and update the database accordingly.
I'm using Microsoft.Office.Interop.Excel
Edit: I'm working with 10.000+ rows per sheet.

I've used the Import/Export wizard to get data into SQL from Excel and it works great. When I want to reverse the process, however, I can't. I've gone through the wizard multiple times and I've done what I think is everything to try to get the data out. What am I doing wrong?

The code Export data from GridView to Excel is working fine but in our office network all machines have MS Office2007 so when user click to export data and save the file it is always saving in the old format and when user wants to open that excel file then a popup asks the compatibility of version to open yes or no. So to open the file user everytime click Yes.
I just want to export data from GridView to Excel in MS Office 2007 version, so that when user click to open then it directly open the file without asking any question.
Following is the code which I used in my projects's web pages:
Therefore I cannot try any other code. I just want minor ammendment's in this code to accomplish this task.

I am trying to manipulate the XML of a Word 2007 document in C#. I have managed to find and manipulate the node that I want but now I can't seem to figure out how to save it back. Here is what I am trying:
// Open the document from memoryStream
Package pkgFile = Package.Open(memoryStream, FileMode.Open, FileAccess.ReadWrite);
PackageRelationshipCollection pkgrcOfficeDocument = pkgFile.GetRelationshipsByType(strRelRoot);
foreach (PackageRelationship pkgr in pkgrcOfficeDocument)

I'm working on a project that I'm trying to export data from textboxes in asp.net website project to a powerpoint file. I writing ofcourse in C#.The whole concept is to use the data the a user inserts to the text boxes and they are sent after clicking a OK button directly to a powerpoint file. I'm using OFFICE 2007 so I'm using powerpoint 2007 for this.A similar concept that I'm already using in the website project is doing the same thing but exporting to a WORD format file. I bumped against this following site a software to perform this and it's called: SoftArtisans. There website is http://www.softartisans.com/ .
Now, if somebody has a clue or a tutorial how I can do this, Export to a powerpoint file I'll be very thankful. I am also using Microsoft SQL Server 2008 R2 to save the data in the database, so if maybe someone knows how to export the data from the textboxes from the website TO the database and then TO the powerpoint file

My users like to upload password-protected Word documents into our custom document management system. I'd like to add a validation to check for the password and refuse the upload if it has a password.
Automating Word - with COM interop - is out of the question because this is a server side application.

I need to create some mail merge documents and was wondering if anyone knew the best way of doing this from asp.net. Currently I have set up .dot template files with bookmarks and then use COM to open these files pass the data and save. I can then stream the file to the users desktop. The issue i have is that to get this working when i release it is by installing Wrord on the server which I would prefer not to do.
way of passing data to word docs and then opening them to the user. The reason why i need to use word, is that the user needs to be able to modify the doc.

How to open word document 2007 and save formate as .xps at server side.
I want the user to open word docx at server side user will click the button to open document which will be execute at server side. I want to show to my client a xps formate of docx which will be converted at server side(from .docx to .xps).
My code is running on local correctly. but at iis5.1 it's not working & giving an exception :-
System.UnauthorizedAccessException: Retrieving the COM class factory for component with CLSID {000209FF-0000-0000-C000-000000000046} failed due to the following error: 80070005.
ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.
To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.

I'm really stuck tryign to figure this out. Converting XLS to CSV is no big deal or at least it seems that way. However, trying to go xlsx to csv seems to be more difficult. For grins, I grabbed some code that is supposed to read a sample xlsx file and convert that into a gridview called GridView1. I figure it can't be much different to turn that into CSV.

It displays message as shown
The file you are trying to open is in a different format than specified by the file extension. Verify that the file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?
When yes is clicked it opens in excel but in some other format I think for I cannot AUTOSUM or sum the values result always as zero for numbers appears as text as " 222" . even if i try to format cells with numbers it does not works.
