Unable To Write File From ASPX Page. What Am I Missing?
I have a folder on webserverwwwroot, called staticContent. The folder
has several message of the day text files, such as RepMotd.text. I have
an admin page, AdminMotd.aspx, that allows a user to view and edit the
contents of the files.
Webserver is running Win Server 2003 64-bit and IIS 6.0. The development
machine is Win XP, using Visual Studio 2005 (thus ASP.Net 2.0.)
In IIS, staticContent folder has Write checked and execute permission is
set to Script Only . In NTSF, the folder grants full permissions to
Network System.
When I try to overwrite an existing file in staticContent, or try to
create a new file, I get a System.UnauthorizedAccessException. The
Application error log on webserver notes that the error is on the page
I am trying to run, that my user name is what I logged in as, that I am
authenticated, and that the thread account name is NT AUTHORITYNETWORK
SYSTEM. Elsewhere, I am able to read these same files and insert them
dynamically into the web page.
This is the code that I am trying to run in AdminMotd.aspx, cut down to
the basics. If it makes any difference, the code is run "in page" and
not as part of a separate code-behind file.
******************
<script runat="server">
Protected Sub MotdChange(ByVal ThisFile As String, ByVal ThisText As
String)
Dim sw As StreamWriter = New StreamWriter(StaticRoot + ThisFile,
False)
sw.Write(ThisText)
sw.Close()
End Sub
Protected Sub RepMotdChange_Click(Byval sender As Object, ByVal e As
System.EventArgs)
MotdChange("RepMotd.text", RepMotdText.Text)
End Sub
</script>
I have traced that the error occurs when New StreamWriter is called,
rather than when actually trying to write to the file. Obviously I'm
missing something, but danged if I can find it.
In IIS, when I try to browse an aspx, I get a popup message asking me if I want to open or to save the file instead of actually browsing to the page. Any idea of what could cause this issue?
I have an asp.net page that I would like to open up another asp.net page within the first one. Like a parent - child relationship. I need to display a graph in the child on the parent.
What I want to be able to do is create a user control that will display an entire page page within it. Does anyone know how to do this or better yet have any same code?
I am trying to change text in the div tags of my page with values from an object obtained from a server side script but the object is not accessable to the client script. I get an object required error but I know the object exists and is correct becuase I can write the query string value and properties of the object with a server script. I also tried to access the div tags from the server script but this also resulted in an object required error.
I am currently facing some difficulties in accessing my web page. I am creating my company intranet website. Currently, I am developing my webpages in my local machine with IIS activated. When i run the website from my local machine's IE by typing //<computer name> my webpage displayed.
However when I do the same thing from another machine in the network, I got the error "The page cannot be displayed".
I have a file in a top level directory called inc_protect.asp. I'm trying to include that file in a page called tree.asp. The code to include the file is
The server returns an error saying that the file is not found. Anyone have any suggestions on this? All files are asp script. The tree.asp is in a folder called SupServ directly below inc_protect.asp... Can these not go backwards?
I first noticed this in my own app. Images would show up missing [red X] randomly on IE 6.0.2800.1106 on Windows 2000 server.
I then was able to repro this problem on Microsoft's website!!! The page I used was http://www.microsoft.com/windows/ie...sp1/default.asp After pressing [F5] to refresh the page six times, I noticed missing images on the page.
This problem seems to be very reproducible. I coded a sample ASP page which references the same images 10 times on the same page. Loaded in IE. Upon pressing [F5] several times, the images will be identified as missing [red X]. Refresh the page again, it's fine.....etc.
I'm up-todate with all latest MS patches. Has anyone else seen this problem?
I have an aspx page that has the "include" code in it which includes another page that displays information. I also have an upload page that allows users to upload a simple html document onto the server. The include code calls that html page to display the text on that page.
The problem is when the user uploads that html page, the aspx page does not refresh to reflect those changes, even if the user hits refresh in their browse. However, if I manually connect to the server and open the aspx page that contains the code and hit save then the webpage updates to reflect the changes that were made to the include page. Can anyone help me fix this problem?
I would like to display a text file using aspx. I realise that I can add a key for a text file in the web.config file. But what do I do after that? I would like to use c# to do this and I woudl like to try to understand how it can be done with a dll?

I have 2 ASPX files. One is the main, the other a smaller one which is the center part of the main ASP file. Now, how do I load the 2nd ASP into the first one?
Something was wrong with my IIS 'Service unavailable', I decided to uninstall IIS and then reinstall it, then the simple pages can be viewed but the aspx pages not. Then I uninstall SQL server 2005 and Visual Studio 2005 and reinstall it.
Now I can view simple pages but not aspx pages, but when running from the debugger of Visual Studio, it Works good. When I access an aspx page 'The page cannot be found' error occurs

I am using Windows 2003/IIS 6. The following event occurs during the day. i want to debug the culprit ASP page which is causing this, but having hard time without knowing on what page and website where the error occurs. May anyone have any idea:
1)how to change the server configuration so it will log the page, or 2) is the error log stored elsewhere (i checked onWINDOWSsystem32LogFilesHTTPERR, but it logs different sort of errors), or 3)is there another way to log only errors (we have an internal error monitoring system, but this error seems to escape it. maybe it's on global.asa)? Code:
I've installed Windows Server 2003...I created a HelloWorld.aspx file and its associatied HelloWorld.vb file and stored both files in the wwwroot directory.
When I put http://localhost/helloworld.aspx on the Address line of my IE browser and press enter, I get the following error msg:Access to..."C:WINDOWSMicrosoft.NETFrameworkv1.1.4322 Temporary ASP.NET Files oot2135a5088d69a834" is denied.
This works on my laptop which has XP Pro installed.
I am having problems opening a .aspx file. I have installed the .NET 1.1 Framework. When I go into IIS,Websites, Default Website, then look at the properties under documents, default.aspx is not listed.Is there something that I need to configure to add aspx?

Error which i got:Server Error in '/' Application. --------------------------------------------------------------------------------
Runtime Error :
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".
I have a IIS server somewhere hosting an aspx website. Whenever i tried to access the website after some times, my browser will like wait about 10-20 seconds before showing the contents. But after that, subsequent pages is load up almost instantly. The page is not heavily loaded and every pic should be cached.
And sometimes, after 1 or 2 days didn't access the site, when i tried to access again, it will never load up the page. My IIS server is never shutdown running 24/7. I have to go to my IIS server and move around with the mouse then go back to my workstation and try again in order for it to work. (My IIS server (also my Internet gateway) will not go into Sleep mode because i still can surf from my workstation.)
We are hosting a web site, and within this web site we are trying to open a .aspx page within the DMZ. Is there anyway to do this? We are currently running Windows 2003 on both servers, and both servers are running IIS. Redirecting the page of course does not work, any other ideas?
I am working on a project where the site was already created using frames and .aspx pages. I was asked to update pages as well as add new functions. This project is an online training course for internal use only.
I need to put a Print Button on the left frame called "buttons.aspx". I need it to print whatever current content is on the main page. So, of course this will vary from page to page because each has a different file name such as 3_1.aspx and 3_2.aspx. I was able to get the Print function to work but it only printed the "buttons.aspx" page which was nothing more than a few navigational buttons.
