I have the following code for creating a file if it does not exist and overwriting it if it already exists:
FileStream fsExe = File.Create(DestExePath, 4096);
BinaryWriter bw = new BinaryWriter(fsExe);
What ever I write to the BinaryWriter, it is getting appended to the "DestExePath" instead of overwriting the original file.
if i click submit.. a file is then created in xml format but if i enter new data it will overwrite the same file how do i stop this..
this is the code i am using
Protected Sub btnWriteXML_onClick(ByVal sender As Object, ByVal e As System.EventArgs)
Try
Dim enc As Encoding
Dim objXMLTW As New XmlTextWriter(Server.MapPath("contact.xml"), enc)
objXMLTW.WriteStartDocument()
objXMLTW.WriteStartElement("Feedback Form")
how do i stop this from overwriting?
what is the best way to append data onto a file download? I figure that i can make my own class that implements InputStream and just consolidates two input streams (the file first, my additional data to append second.) but is there an existing view class that i can use to just return an InputStream or will i have to roll my own view class as well?
View 1 RepliesI have created a CSV file on the server and want to send it to the user using the following code:
Dim strPhysicalPath As String
strPhysicalPath = Server.MapPath( "CSV/" & PathVirtual)
Dim objFileInfo As System.IO.FileInfo = New System.IO.FileInfo(strPhysicalPath)
Response.Clear()
Response.ContentType = "application/vnd.ms-excel"
Response.AddHeader("Content-Disposition", "attachment; filename=" & objFileInfo.Name)
Response.AddHeader("Content-Length", objFileInfo.Length.ToString())
Response.WriteFile(strPhysicalPath)
Response.Flush()
Response.End()
This seems to work fine except when the downloaded file is viewed in Excell the html code behind the page from which it came is also appended to the file. Does anyone have any idea why it does this?

View 1 RepliesI have an asp.net application. I want to add a global.asax and global.asax.cs file to my project. In the IDE when I select to create a new global.asax file, the option to create a CS code behind file is greyed out. When the global.asax file is created, no code behind is created, instead code is placed in the global.asax file and the global.asax.cs file is never created? Why is the option for a C# code behind file greyed out?

Just wondering if there is a way to create a file using open filedialogue. I actually need a functioanlity a little bit different from Save Dialog. I have to use OpenFile dialogue because I want user to select file. In addition to this, if the file is not available and user just write a name of the file then it should pop-up like "File not found, would you like to create one?
View 2 RepliesI'm using System.IO.File.Create to create a file. I'm not writting to it with a stream writer, just creating it.
I get a server error in the front end when the app trys to open the newly created file - that the file is in use. Garbage collection then seems to come along and a few minutes later all is OK.
Now I know if I was using Streamwriter I would have to close it. Does the same apply to creating?
I've read that opening a stream writer to the file then immediately closing it will fix this.

View 1 RepliesI am downloading file from database using the following code. This code downloads an excel file from the database which has a macro attached to it when it is opened. This macro reads file name of the excel file and uses it for its computation. Everthing works file if user saves the file on his harddisk and then open if but if he directly opens the file from the dialog(by hitting 'Open' button) then file name of the opened excel file comes out be the name of the webform that has the above code and this leads to error in the macro. Is there any option through which i can control the name of the file if user directly opens the file from dialog or the option to disable or remove 'Open' button form the dialog?

I am creating an ASP.net website where some articles can be uploaded. I need that my users can get PDF version of it by clicking on a button. For this functionality I am using itextSharp. I am considering the following two options.
1. I will create the PDF file once(on first request) and reuse it always by checking for the existence of it.
2. I will create it on the fly and delete it as soon as the PDF file is delivered to the client. The first approach will lead to faster PDF delivery where as the second approach will lead to saving space.
I am also wondering if this can be possible without saving the PDF on the server in the first place.
