I have been working through 'Beginning ASP.NET 1.0 with C#. The examples work well. However I have run into a problem on Chapter 16 "Try it out - Using a Compiled Component". I get a compilation error CS0246 The Type or namespace name 'WroxComponents' could not be found. Line 1 of UseMyFirstComponent.aspx is highlighted.

Line 1: <% Import Namespace="WroxComponents" %>

I think I have followed the course of this tutorial fairly well. The only change I had to do was modify the CompileMyFirstComponent.bat to reflect the directory structure I had.

set indir=C:\Inetpub\wwwroot\DotNetDev\BegASPNET\Ch16\ MyFirstComponent.cs
set outdir=C:\Inetpub\wwwroot\DotNetDev\BegASPNET\bin\ MyFirstComponent.dll
csc /t:library /out:%outdir% %indir%

The component compiled to a dll ok and was placed in the bin folder.
The source MyFirstComponent.cs and UseMyFirstComponent.aspx are straight from the book.

Any Suggestions

If you think I need to furnish more info on this, please let me know.

Hi Dave,

check it out:
change the second set row as follows:
set outdir=C:\Inetpub\wwwroot\DotNetDev\BegASPNET\ch16 \bin\MyFirstComponent.dll

the \bin-directory must in the application folder.

I hope, it runs...
:)

Hi MDaniel,
   I had at oun point set up a bin directory off the ch16 directory and copied MyFirstComponent.dll in there, the same error was generated. I tried out your suggestion and modified the CompileMyFirstComponent.bat so the compiled dll eas saved to the local bin folder, the same error was generated.
   Also the directory structure originally used on the book was a little wierd:

Dlls were compiled to C:\BegASPNET\bin
even though the application folder path was to be
C:\BegASPNET\Ch16

Even that should not work, unless possibly the path to the dll is specified elsewhere.

Hi Dave,
if your application path is 'C:\BegASPNET\Ch16' then you've to save the dll-file in 'c:\begaspnet\ch16\bin\'.
When you don't have defined the application path and you're working in standard root-path then you have to save the dll-file in 'c:\inetpub\wwwroot\bin'
I had similar problem (i worked with the 1st edition). After i've found the error in the book, the code run without problem.

Hi MD,
   First I tried putting the dll in c:\inetpub\bin and hey it worked !!!. Now I imagine that would get cluttered after a while. I set up the source in C:\BegASPNET. Again I had success if the dll was in C:\BegASPNET\bin - as per the book. If I put the dll in C:\BegASPNET\Ch16\bin it would not run. Is there a way of defining the application path outside of Visual Studio?
Thanks for all your help

Regards

Hi Dave,

yes, you can define the application path with IIS.
