I have some pdf files that get attached to emails and are emailed out through a web application. Sometimes this causes the PDF files to get locked and I cannot delete them from the server (even after the email has gone out). I get the message "The process cannot access the file 'D:myfile.pdf' because it is being used by another process".

after i can copy my file to another folder i realised that if this webapplication is used by multiple users at once, then some users are going to get locked out because each one is trying to copy those files.
so how do i tell the user thats trying to use a file to wait untill the file is available.
StreamWriter WriterTotxt = new StreamWriter("date.txt", false);
DateTime LastAccess = File.GetLastWriteTime("path.dbf");
WriterTotxt.Write(LastAccess);
WriterTotxt.Flush();
WriterTotxt.Close();
string ReadTextFile = File.ReadAllText(txtFile);
DateTime test = Convert.ToDateTime(ReadTextFile);
if (File.GetLastWriteTime(LatestUpdatedTime).CompareTo(test) > 0)
{
File.Copy(Path.Combine(sourcefile, fName), Path.Combine(destinationfile, fName), true);
}

View 3 RepliesI have a web page in my project that views a selected pdf file. The problem is the file stays locked with the process w3wp.exe which I assume is the adobe file reader or something. How I can release this process after viewing it? Or another way of viewing it without locking the file?
Here is how I am doing it:
Code:
Dim File1 As String = System.Configuration.ConfigurationManager.AppSettings("Report")
Dim R1 As String = Page.Request.QueryString("r")
If R1 <> "" Then
Dim path As String = File1 & R1

I have a page where users can upload an excel file and it is read into our system. I am using the Jet.OLEDB.4.0 provider to read the files. I access the file one time to read out the header names and then allow the user to select which field each column will be read into on import. For some reason after this read the file is locked and the next time I try to access it to do the data import I get the "File in use" message. Each time I open a connection it is closed so I am not sure why the file is being locked.
