Hello all,
I have an asp.net page uploading a file to D driver. It works well with ASP.NET server.
<br />
protected void Button6_Click(object sender, EventArgs e)<br />
{<br />
FileUpload1.SaveAs("D:\\a.txt");<br />
}<br />
when I published (to IIS) and ran it from IE, it caused an error: Access to the path 'D:\a.txt' is denied as following.
<br />
[UnauthorizedAccessException: Access to the path 'D:\a.txt' is denied.]<br />
System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath) +651<br />
System.IO.FileStream.Init(String path, FileMode mode, FileAccess access, Int32 rights, Boolean useRights, FileShare share, Int32 bufferSize, FileOptions options, SECURITY_ATTRIBUTES secAttrs, String msgPath, Boolean bFromProxy) +1038<br />
System.IO.FileStream..ctor(String path, FileMode mode) +64<br />
System.Web.HttpPostedFile.SaveAs(String filename) +87<br />
System.Web.UI.WebControls.FileUpload.SaveAs(String filename) +22<br />

System.Web.UI.WebControls.Button.OnClick(EventArgs e) +105<br />

System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) +33<br />
System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1746<br />
<br />
Best regards,
P/S:
The code for this problem is here:
I have an ASP.NET and this is the code in default.aspx:
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<asp:FileUpload ID="FileUpload1" runat="server" />
<asp:Button ID="Button6" runat="server" önclick="Button6_Click" Text="Button" />
<br />
<br />
</form>
</body>
</html>
And here is the code into default.aspx.cs
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button6_Click(object sender, EventArgs e)
{
FileUpload1.SaveAs("D:\\a.txt");
}
After compiling the project, I published it as following:
clicked right mouse on it and selected "Publish Website". Then I copy published files to a folder example (a subfolder of C:\Inetpub\wwwroot). Finally, I ran IE and fill in the address: http://localhost/example/default.aspx, clicked button_6, and got the error.
I installed IIS on my local computer with version v5.1
Thanks,

Does D: Drive exist on your server? Is it writeable, or is it a CD Drive? Do you have permissions to write to the root of D: Drive? Does your IIS process user have permissions to write to the root of D: Drive?
|
|
|
|
|
Yes, D: Local Drive exists on my computer.
I do not know whether I have permissions to write or not, but when I run the page using ASP.NET Server, It works well. After I published and then used IIS Server, It threw the error.
I do not know how to check permissions both the root of D: Drive and IIS process, and I need your help.
Thanks,

Your computer is the server ?

A website should not have permission to read or write above the application root, so even if you have a D drive on your server, I'd expect this not to work.

No, D: is my Local Drive and my computer is not a server. I have that project on my personal computer.
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<asp:FileUpload ID="FileUpload1" runat="server" />
<asp:Button ID="Button6" runat="server" onclick="Button6_Click" Text="Button" />
<br />
<br />
</form>
</body>
</html>
And then I have an event to fileUpload1 Control:
protected void Button6_Click(object sender, EventArgs e)
{
FileUpload1.SaveAs("D:\\a.txt");
}
I ran the project from virtual server of ASP.NET, it worked well.
But when I published it to IIS server, it threw that error.
Thanks,

So your computer IS where IIS is running, and therefore is the server, right ?

Published it how ? Is IIS running on your local machine ?

Yes, I installed IIS into Windows XP on my personal computer.

Yes, IIS is running on my local machine. After creating a ASP.NET project in Visual Studio 2008 and writing code as I mentioned above, then I compiled the project, clicked right mouse on it and selected "Publish Website". Then I copy published files to a folder example (a subfolder of C:\Inetpub\wwwroot). Finally, I ran IE and fill in the address: http://localhost/example/default.aspx, clicked button_6, and got the error.

If you answered my questions, I'd understand what your situation is, and I'd be able to give you a definitive answer. Is IIS running on your desktop, or on a remote computer ? Where did you publish your site to ?

If I don't, why it can run correctly on Visual Studio 2008?

I believe that the web server that's built in to visual studio doesn't enforce the sort of security that IIS does, simply because no-one is going to run a live website with it. Imagine if my site is on a web host that runs a lot of other sites. They are probably all going to be folders under the IIS root. So, if I were to write code that looks for files with a path starting in a .., I could try to read files that belong to another site. That's just one reason why IIS doesn't let you read or write above the root of the web application.

Your answer is absolutely right. If I save the file to one of the folders under the project, it works with IIS.
So I wonder if there is any way to write directly to another location like I did (Configure IIS for example) because when I searched information, some people say that there is a way by adding this line in web.config file between tag <system.web> and </system.web>:
<identity impersonate="true"/>
I tried, but it did not work.
Thanks for your help,

What abt this code..!
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button6_Click(object sender, EventArgs e)
{
FileUpload1.SaveAs("D:\\a.txt"); <big><----</big>
}
use the following code..!
FileUpload1.SaveAs(@"D:\SomeFolderName\" + FileUpload1.FileName);
Your wasting the time..!

That code placed in default.aspx.cs file is used to save a file whose path is got from FileUpload1 Control to D:\a.txt (Actually, it saves and change the original file's name into a.txt).
If I modify it as following, it works:
protected void Button6_Click(object sender, EventArgs e)
{
FileUpload1.SaveAs(Server.Map("~")+@"\a.txt"); <----
}
But I do want it to do directly on D: Drive (or another Drive, not C: Drive)
Thanks,

Have You tried the above code..!
Make sure a folder is created..!

Yes, I tried and it worked, but this approach is not exactly what I want. If the path is got from Server.Map("~"), I just only work with C: Drive because wwwroot folder of IIS is only placed on C:Drive. I want to work with D: Drive instead.
Thanks,
