I have a WCF service method that's running in a worker thread I spin from another method. I need to map a relative service app path ("~/Templates/a.template") to the physical path ("D:WebTemplatesa.template"), but I can't use HttpContext.Current.Server.MapPath because HttpContext.Current is null in a worker thread. How else can I reach MapPath method?

I have a ASPX page which queries from a database. Once we have the dataset it is bound to a gridview and displayed on the page. All this happens in the Page_Load event.Ofcourse this a simplistic approach. What is the best way to inform the user that data is being retrieved and when we have the data to update the page with the results in the dataset.I want all this to happen within the same ASPX page and do not want to hop around pages to achieve this. I looked at update panels however it wasn't clear to me how this could be done with an update panel without having a control which triggers the update for the update panel. There are no controls on my page whhich initiate the database query, it occurs as the page is loaded
View 1 RepliesI am developing an asp.net application which provide a UI for user to submit some kind of job.
Behind the scene, i created a thread to sleep around certain mintues and then process the submmitted job. I would like to ask this is right way to create some worker threads to process the jobs? any risk in threading? any other alternative?
currently, i am facing the timeout of asp.net session. For example, the period of sleeping is 25 mins, the thread will not be processed because the asp.net session is timeout in 20 mins.
i upload a file using ftp, and to not get my GUI stuck i use a thread which do the Job.
I want to display in a label control text value the remaining bytes.
how can do this. (i use VS.NET 2005, Web application)
What is the difference between those two? If I only want to retrieve the absoluate path to an image on web server, is Server.MapPath safer in any case? I'm using Page.MapPath right now, but it won't work if control was created in WebService since control.Page property become null? Whether Server.MapPath always work?

View 1 RepliesI'm new to threading and have used it successfully, but limited. I can spawn a thread and have the main thread reference variables in the spawned thread, but I don't know how to allow the spawned thread to reference (and update) variables in the main thread.
Any example threading code I've seen on the web appears to be WAY more complicated than what I do, so I am unable to understand or integrate into my code.
Here is a quick example of how I use threading:

I am reading the Asp.net security documentation on msdn.I come across these tow terms and get really confused.
# WindowsIdentity = WindowsIdentity.GetCurrent()
which returns the identity of the security context of the currently executing Win32 thread.
# Thread = Thread.CurrentPrincipal
which returns the principal of the currently executing .NET thread which rides on top of the Win32 thread.
I have a password page and when someone enters an incorrect password I want to simply foil a brute force attack by having
bool isGoodPassword = (password == expected_password);
lock (this)
{
if (!isGoodPassword)
Thread.Sleep(2000);
}
I would expect that this would allow all correct passwords without stalling, but if one user enters a bad password another successful password from a different user would also be blocked. However, the lock doesn't seem to lock across ASP.NET threads.

I'm having a bit of trouble loading an XML file with ASP. This is the location of the XML file (it's a UNC url):
\ilife104 eamdiskSharedIntegrationSystemdevDataprcImportFactSetFeedsfileList.xml
And this is my code:
<%
'load the XML file..
Option Explicit
Response.Buffer = True
Dim xml
Set xml = Server.CreateObject("Microsoft.XMLDOM")
xml.async = False
xml.load (Server.MapPath("\ilife104 eamdiskSharedIntegrationSystemdevDataprcImportFactSetFeedsfileList.xml"))
Dim name, retrieved
name = xml.documentElement.childNodes(0).text
retrieved = xml.documentElement.childNodes(2).text
Set xml = Nothing
%>
It gives the error:

An invalid '/' or '' was found in the Path parameter for the MapPath method.

I have some code that works fine when I need to delete some image files from a directory on my web server:
Dim ImageURL As String = dsImages.Tables(0).Rows(iImgRow).Item("ImageURL")
Dim physicalName = Server.MapPath(ImageURL)
oUpload.DeleteFileFromServer(physicalName, iAdid, iImgID)
.but I am running into a problem when a maintenance task running in a separate thread at set intervals determines that files like the above need to be deleted:
Dim ImageURL As String = dsImage.Tables(0).Rows(i - 1).Item("ImageURL")
Dim iImgID As Integer = dsImage.Tables(0).Rows(i - 1).Item("ImageId")
Dim physicalName As String = HttpContext.Current.Server.MapPath(ImageURL)
oUpload.DeleteFileFromServer(physicalName, iAdID, iImgID)
In this latter case, HttpContext.Current.Server.MapPath(ImageURL) has a value of Nothing.Is there a way to get the full path for this case?
I want to make an oledbconnection for my access database. I want to put the connection string in the web.config but I learned that server.mappath does not work in there. I want to use the server.mappath. Can I put the connection sting in a session variable into the global.asax in the session start?
View 2 RepliesWhere does httpcontext.current.server.mappath start?
I don't get it... it doesn't return a path.
My webservice is ran when I debug my application :S.
i want to save a picture in one folder up from there where i call the mappath how can i do that?
for example i am here
c:usersmevstproject
and i want to save the file here
c:usersmevst
i want to do that with mappath in order to work in the server.not only in my pc..
When my ASP.NET site uses documents (e.g. XML), I normally load the document as follows:
Server.MapPath("~DocumentsMyDocument.xml")
However, I would like to move the Documents folder out of the website folder so that it is now a sibling of the website folder. This will make maintaining the documents considerably easier.
However, rewriting the document load code as follows:
Server.MapPath("../../Documents/MyDocument.xml")
results in a complaint from ASP.NET that it cannot 'exit above the top directory'.
how I can relatively specify the location of a folder outside the website folder? I really don't want to specify absolute paths for the obvious deployment reasons.
in my Global.asax I have a timer and every 24 hours it creates an instance of a class and calls a method to send reminder emails with an attachment. In this method I am getting the current HttpContext and using Server.MapPath to get the path to the attachment, but it is always null. I guess this is because Application_End has been called between the last user accessing the site and the method being called.
As a workaround I am setting the timer interval to 19 minutes but I would rather not call the method 36 times a day when only once is required.
Is there any way, apart from hard coding the path, to ensure the HttpContext is not null?
The layout of my web app is C:inetpubwwwroot<sln folder><web app folder>. So the image folder in my web app would be the previous path images.
When I try to save to my images folder from a FileUpload control and use Server.MapPath, it drops my <sln folder>, so the path is incorrect. How do I fix this? I figured Server.MapPath just moved up the folder until it hit a drive, no?
I have a virtual directory setup in IIS6. This maps to a shared network drive.
I can correctly map the path using
string mappedPath = HttpContext.Current.Server.MapPath(path);
I then create a DirectoryInfo object as I want to find some files in the directory.
DirectoryInfo updateDirectory = new DirectoryInfo(mappedPath);
But then updateDirectory.Exists is false?? I can take the string from the mappedPath and copy into Start->Run to get to the path so I know it exists. I am authenticating to the webservice using integrated windows authentication and have permissions to the necessary folders.
Is there something obvious I'm missing in the code? Or is this purely set-up and configuration of IIS etc.?
I have image files stored in "VS_ProjectResourcesImages".
When I use the following code:
String str = Server.MapPath("a.png");
str becomes "VS_Projecta.png".
Why isn't it returning the full path?
I have a web application that uses Server.MapPath to specify the exact physical path of as part of upload image.
For example if I do Server.MapPath("/")
I get this:
\boswinfs04homeusersweb2676username
I was expecting something like this:
d:folder
I need to use Server.MapPath not only for image upload but several other uses.
