For the method:
System.Xml.Xsl.XslCompiledTransform.Load("unqualified.xsl")

On a device without Stylus Studio installed,
refers to the ASP.NET application path (the working directory).

On a device with Stylus Studio installed,
refers to the Stylus Studio\bin directory.

Can you comment on whether this is expected, and if not, file a bug report for me?
The .NET documentation provides examples of using the method unqualified, can you recommend a fix to make my development PC operate normally?

Hi Shannon,

I am not sure I understand the problem.
How do you run the your c# code?

In you are running an Active Server Page it's better to use the full path to the resource.

It is always dangerous rely on the "current directory" because the process hosting your transformation could change it.

See the ASP documentation to map a virtual to a real path

Hope this helps

I'm aware of that, which is why my application current works.
However, I didn't ask how to fix my application.
I asked how to fix yours.

That's the twice (and I've only asked two questions thus far) that I've asked about a potential bug in your application, and you've told me I should change my design strategy to address it. Stylus Studio is supposed to save me time, not cost it.

Now, obviously, the code I gave you is not my application. It is a test meant to demonstrate (without providing you proprietary code) that the installation of your product made the .NET library perform in a fashion other than that documented by Microsoft. Did I overlook something?

Given that I did not, if I had security concerns, it would be that this product changed the working directory for compiled transforms running in web pages on my development PC. That sounds like a risk to me.

Stylus Studio doesn't execute any code that could possibly change the working directory of other processes other then its on sub-processes for instance when it executes command-line tools.

We will try to reproduce the behavior in house.

If you have any additional details let us know.

Thank You
Ivan

I wonder how your appliccation could possible work with a relative path.

I tried to build a sample ASP+ page with the following code

public partial class _Default : System.Web.UI.Page {
protected void Page_Load(object sender, EventArgs e){
XslCompiledTransform xslt = new XslCompiledTransform();
xslt.Load("sampleBooksToCatalog.xsl");
}
}

and I get

Line 14: {
Line 15: System.Xml.Xsl.XslCompiledTransform xslt = new System.Xml.Xsl.XslCompiledTransform();
Line 16: xslt.Load("sampleBooksToCatalog.xsl");
Line 17: }
Line 18: }
Source File: c:\inetpub\wwwroot\ASPTest\Default.aspx.cs Line: 16
Stack Trace:
[FileNotFoundException: Could not find file 'C:\WINNT\system32\sampleBooksToCatalog.xsl'.]
System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath) +2014381
...

Notice that IIS uses C:\WINNT\system32 as base path
