There is a section in my site that users can download files. I want that As users push the download button and hit "Open" button instead of "save" button, the download get open with it's own program. For example a pdf file should not en with ms word. Now my problem is that, as a user open the file an XML extension will be added to the download URL!!
For example it should be:
www.mysite.com/inputfile/12.dox
but instead of that, it goes for
www.mysite.com/inputfile/12.dox.xml
Here is my cod:
protected void LinkButton1_Command(object sender, CommandEventArgs e)
{
int idx = Convert.ToInt32(e.CommandArgument);
string Manuscript = GridView2.DataKeys[idx].Value.ToString();
string fileName = System.IO.Path.GetFileName(Manuscript);
string contenttype = String.Empty;
string ext = Path.GetExtension(fileName);
Response.ClearContent();
Response.ClearHeaders();
switch (ext)
{
case ".doc":
contenttype = "application/msword";
break;
case ".docx":
contenttype = "application/msword";
break;
case ".xls":
contenttype = "application/msexcel";
break;
case ".xlsx":
contenttype = "application/msexcel";
break;
case ".jpg":
contenttype = "image/jpg";
break;
case ".png":
contenttype = "image/png";
break;
case ".gif":
contenttype = "image/gif";
break;
case ".pdf":
contenttype = "application/pdf";
break;
}
Response.ContentType = contenttype;
Response.AppendHeader("Content-Disposition", "attachment; filename=" + fileName);
Response.TransmitFile(Server.MapPath(Manuscript));
Response.End();
}
I have developed a website using Asp.net. In a section of my program users need to download some variable files. (Jpeg,Pdf,doc,docx...) As they push the download button and hit "Open" button instead of "save" button, the file will open with Adobe Acrobat. The problem is that if it is a word file, again it will be open with Adobe Acrobat!
How can i avoid this and each file open with it's own program?
I used this cod in my behind cod:
protected void LinkButton1_Command(object sender, CommandEventArgs e)
{
int idx = Convert.ToInt32(e.CommandArgument);
string Manuscript = GridView2.DataKeys[idx].Value.ToString();
string fileName = System.IO.Path.GetFileName(Manuscript);
Response.Clear();
Response.ContentType = "application/pdf";
Response.AppendHeader("Content-Disposition", "attachment; filename=" + fileName);
Response.TransmitFile(Server.MapPath(Manuscript));
Response.End();
}
Like this :
string ext = System.IO.Path.GetExtension(this.File1.PostedFile.FileName);
string contenttype = String.Empty;
OR
string ext = Path.GetExtension(filename);
switch(ext)
{
case ".doc":
contenttype = "application/vnd.ms-word";
break;
case ".docx":
contenttype = "application/vnd.ms-word";
break;
case ".xls":
contenttype = "application/vnd.ms-excel";
break;
case ".xlsx":
contenttype = "application/vnd.ms-excel";
break;
case ".jpg":
contenttype = "image/jpg";
break;
case ".png":
contenttype = "image/png";
break;
case ".gif":
contenttype = "image/gif";
break;
case ".pdf":
contenttype = "application/pdf";
break;
}
Use
FileInfo fInfo = new FileInfo(fileName);
string fileExtn = fInfo.Extension;
How do display a Word document on an asp.net page retrieved from a SQL Server database table?
I have uploaded the word document into database, please see the code,
Now I want to display the word document details in gridview, when I click the word document name in the gridview then the word document should display in webpage. Please help me how to do this.
protected void btnUpload_Click(object sender, EventArgs e)
{
string filePath = FileUpload1.PostedFile.FileName;
string filename = Path.GetFileName(filePath);

//Set the contenttype based on File Extension
switch (ext)
{

}
if (contenttype != String.Empty)
{
Stream fs = FileUpload1.PostedFile.InputStream;
BinaryReader br = new BinaryReader(fs);
Byte[] bytes = br.ReadBytes((Int32)fs.Length);
//insert the file into database
string strQuery = "insert into tblFiles(Name, ContentType, Data)" +
" values (#Name, #ContentType, #Data)";
SqlCommand cmd = new SqlCommand(strQuery);
cmd.Parameters.Add("#Name", SqlDbType.VarChar).Value = filename;
cmd.Parameters.Add("#ContentType", SqlDbType.VarChar).Value = contenttype;
cmd.Parameters.Add("#Data", SqlDbType.Binary).Value = bytes;
InsertUpdateData(cmd);
lblMessage.ForeColor = System.Drawing.Color.Green;
lblMessage.Text = "File Uploaded Successfully";
}
else
{
lblMessage.ForeColor = System.Drawing.Color.Red;
lblMessage.Text = "File format not recognised." +
" Upload Image/Word/PDF/Excel formats";
}
}
private Boolean InsertUpdateData(SqlCommand cmd)

To my knowledge you have to convert the word document to .html to display it in a web page itself. You can check out this article that shows you how to do it. http://www.c-sharpcorner.com/UploadFile/munnamax/WordToHtml03252007065157AM/WordToHtml.aspx
I guess what I would do is convert the ms doc file to HTML at upload and then store that along with the .doc or .docx. The HTML you would select and display it in an iframe and the actual .doc file you could use if the user wanted to download it.
Response.Flush method is not working. I am getting the data at pdfContent but it is not opening the PDF documnet. Below is the code. Please help.
public ActionResult PdfClick(int requestid)
{
BusinessRequestController bsnrqstcntrlr = new BusinessRequestController();
try
{
int DocId = (new BusinessRequestBR()).GetBaseLineDocumentsForSearch(requestid);
byte[] PdfContent = (new BusinessRequestHelper()).GetBaseLineDonload(DocId);
Response.Buffer = true;
Response.Clear();
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment; filename=" + "BaseLine_Doc" + "_" + DocId + ".pdf");
Response.BinaryWrite(PdfContent);
Response.Flush();
return Content("");
}
catch (Exception ex)
{
throw this.log.CreatePropagatedException(ex);
}
Instead of using
return Content("")
use this:
return File(
PdfContent,
"application/pdf",
string.Format("BaseLine_Doc{0}.pdf", DocId)
)
There is no need to manipulate the response. Just return the correct result type.
Pulling out code from my running project
Response.Clear();
Response.AddHeader("Content-Disposition","attachment; filename=\"" + file[0].Name + "\"");
Response.AddHeader("Content-Length", fileSize.ToString(_culture));
Response.ContentType = Path.GetExtension(file[0].Name).GetMimeType();
Response.BufferOutput = false;
Response.AddHeader("Accept-Ranges", "bytes"); //tell the client that we accept byte-range requests
while (totalBytesRead < fileSize)
{
if (!Response.IsClientConnected)
{
System.Diagnostics.Debug.WriteLine("--> Client disconnected");
break;
}
int bytesRead = fs.Read(buffer, 0, buffer.Length);
Response.OutputStream.Write(buffer, 0, bytesRead);
Response.Flush();
totalBytesRead += bytesRead;
}
Response.End();
This code works for me every time, please manipulate according to your need.
Note: Variables are defined above the code.

You are not sharing your specific error but this is likely the cause. Increase the maxRequestLength size in your web.config file. The default is 4096 KB (4 MB).
<configuration>
<system.web>
<httpRuntime maxRequestLength="size in kbytes"
...
/>
Allocating an array size of data will, eventually, fail. Look into streaming semantics.
Check your configured maxRequestLength
