In my application I store a string as content of a HTML file.
How can I preview this content (assuming that it's modified from original content) in browser but not having to save it to disk locally.
And the preview to be in another tab or window.

In my application I store a html code in a string, for example:
string myHtml = "<html><body><input type ='text' value='hello'/></body></html>";
How can I preview this html in another window pressing some button?
<asp:Button ID="PreviewButton" runat="server" Text="Preview" OnClick="PreviewButton_Click"/>
I've tried :
protected void PreviewButton_Click(object sender, EventArgs e)
{
myHtml = "<html><body><input type ='text' value='hello'/></body></html>";
Response.Write(myHtml);
Response.End();
}
And it works, the preview it's opened but in the same window.
I am using ASP.NET 3.5 with iTextSharp and I have the following code:
var templatePath = Server.MapPath(@"~/Templates/template1.pdf");
var newFilePath = Server.MapPath(@"~/TempFiles/new.pdf");
PdfReader pdfReader = new PdfReader(templatePath);
PdfStamper pdfStamper = new PdfStamper(pdfReader, new FileStream(newFilePath, FileMode.Create));
AcroFields pdfFormFields = pdfStamper.AcroFields;
pdfFormFields.SetField("Box1", "007");
pdfFormFields.SetField("Box2", "123456");
pdfStamper.FormFlattening = false;
pdfStamper.Close();
Response.ClearContent();
Response.Buffer = true;
Response.ContentType = "application/pdf";
Response.AddHeader("Content-Disposition", "attachment;filename=new.pdf"));
Response.WriteFile(newFilePath);
Response.End();
The above code fills out a pdf file and saves the new file to the TempFiles folder. It then prompts the user to either save or open the file. Can I achieve the same functionality without saving the file to the TempFiles location?
I need to be able to read an excel file from a file upload control but I can not save the file to disk first, it must be done in memory.
[Code]....
Above is my code for reading the data file if it IS saved to disk, but again, I have to be able to do this without saving the file to disk, it must be done in memory. I have not been able to find any sample code anywhere on how to do this from memory, everything seems to force the file be uploaded, saved to disk, and then read in the connection string, which again I can not do.
i need to save multiple documents stored in SQL server as Image type to disk.
What i want to do is "backup" all files in a table (column) to disk, zip them and Response.TransmitFile(FilePath) to client.
I could use C# ot VB but that would require a lot of connections to database or a lot of server memory and i don't want that, becauze there are a lot of files to be saved Since SQL can write files to disk i was thinking about saving those files to disk directly from sql. Something like when u're doing a backup

My website provides a facility to upload images, using the ASP.NET FileUpload control. We accept both jpeg and tiff formats but I have just decided that all tiffs should be converted to jpegs at the time of upload. If possible, I want to avoid saving the original tiff to disk. I would any sample coding for achieving this conversion prior to saving (ideally in VB.NET, though I could always run C# code through a converter).

View 6 RepliesReally weird problem loading a file from disk:
string path = HttpContext.Current.Server.MapPath("~/Datasets/blob.xml");
FileStream stream = new FileStream(path, FileMode.Open);
Throws exception:An exception of type 'System.UnauthorizedAccessException' occurred in mscorlib.dll but was not handled in user code
Additional information: Access to the path 'D:webrootafobDevv1.0.xAFOBDatasetslob.xml' is denied.
The strange thing is it was working 5 minutes ago. I checked permissions on the disk and both the Debugger and ASPNET have read/write rights as do I.
I'm looking for a way of automatically creating a 30 second preview file of an MP3 when it is uploaded through my ASP.NET Web Application.

I have a css file which I want to read from disk and in that content I want to find and replace all linebreaks (do I look for vbCrlf or ...?)
Public Shared Function GetFileContents(ByVal FullFilename As String) As String
Dim filecontents As String = ""
If File.Exists(FullFilename) Then
Dim objStreamReader As StreamReader
objStreamReader = File.OpenText(FullFilename)
filecontents = objStreamReader.ReadToEnd()
objStreamReader.Close()
End If
Return filecontents
End Function
So in the returned variable "filecontents" I want to find and replace any linebreaks.
