What are the options for handling file uploads to reduce the memory footprint? Is there a way to upload in chunks? Is there a way to stream upload directly to disk instead of loading entire file in server memory?
I have the following subroutine in an asp.net application class. The subroutine writes data to a text file upon application login. My question is that if this function was called at the same time by two different users would it cause any kind of error. Is there a need for a try catch?
Public Shared Sub writeToLogFile(ByVal UserName As String) Dim strLogMessage As String = String.Empty Dim strLogFile As String = System.Web.HttpContext.Current.Server.MapPath("~/Log.txt") Dim swLog As StreamWriter strLogMessage = DateTime.Now.ToShortDateString().ToString() " ==> " & UserName
If Not File.Exists(strLogFile) Then swLog = New StreamWriter(strLogFile) Else swLog = File.AppendText(strLogFile) End If
I am trying to understand where the additional file name is coming from in my Page directives Inherits
attribute like so :
inherits ="Track_Milestones2, App_Web_techsrvcs_track_milestones2.aspx.cdcab7d2"
Is the result of this app being published on my local server at one time or could this
page have been compiled on a server ?
Thanks for your insights !

Once again I have trawled the web for a WPF (VB) example of writing to a CSV file. I have found several in C# and Forms VB and managed to work out reading from CSV. However, the writing version I have come up with adds a blank line after each actual line.
Also the first cell written to the CSV file contains some wierd characters just before the genuine content. (i.e. #?!Name1 instead of just Name1); I have shown the code below.
If File.Exists("resources\csvData.csv") Then
MsgBox("resources\csvData.csv doesn't exist")
MyFileName = "resources\csvData.csv"
myCSVWriter = My.Computer.FileSystem.OpenTextFileWriter(MyFileName, True)
For y = 0 To 14
myNewLine = ""

another spanish character issue: I am parsing special spanish characters, removing the tildes (EX: "ÃÂ±" becomes "n") that customers send us in files, in tab delimited files that is.
When the characters are valid spanish characters (like "ÃÂ±") then this is not an issue, however some of the files that we get have characters such as:
Which should actually be:
Has anyone seen this and know any solution? The "ÃÂ±" is fine but I am not certain what to do about the "ÃÂ±".
this is only one example, other spanish characters are listed as a question mark "?" so this is causing some issues.

Obviously I'd expect to at least see the

Where does this control string come from that gets written to the log file??
I'd seen the large log files were all looking like this. I cl
Finally I did manage to build an application that supports unicode characters..
Now my application generates a zip file which contains an XML file. I want to unzip the zip file to view the contents of an XML file.
i am unable to unzip because the name of the zip file/as well as XMl file has Unicode characters(i.e. japanese Name) and it gives some error.
If i generate the XML file with same contents but name of the files in English then i can view the contents of the XML file.
My query is i want to be able to unzip the XML file when the name of the file contains unicode characters in it.
as per my research up till now, we either require a compatible winzip software or we have to create an utility for the same.
I need to know how to go about it. It's a little urgent as well.
Thnx in advance.
