I am just getting started with ASP.NET WebMatrix. I have been reading the 
Inside ASP.NET Web Matrix book and am just getting started with the sample 
project. On about page 5 of part 2 of the book, a vb class is created and 
compiled into a dll using a one-line batch file: 

vbc /debug /nologo /t:library ... DataLayer.vb 

When I execute the batch file, I get the message: 

'vbc' is not recognized as an internal or external command, operable 
program or batch file. 

Any thoughts on what the problem is? Is it necessary to have some version 
of VisualBasic installed in order to use Web Matrix? (I do not). 

Thanks in advance.

Hello.

I think the problem is that you have not added the path to vbc.exe in your 
environment variable ( Control panel --> System --> Advanced --> 
Environment variables ). Add the path to vbc.exe, 
usually "C:\WINNT\Microsoft.NET\Framework\v1.0.3705", close your cmd and 
open it again. Try again.

Philip,

Thanks very much for your reply which it appears was right on target. 
However, after adding the path and running the batch file again, I now get 
the error:

vbc : command line error BC2012 : can't open 'bin/DataLayer.dll' for 
writing

Here's the full text of my batch file that I am attempting to run:

vbc /debug /nologo /t:library /out:bin/DataLayer.dll /r:System.dll /r:Syste
m.Xml.dll /r:System.Web.dll /r:System.Data.dll DataLayer.vb

Any thoughts on what the issue is?

Hello!

I really dont know what couuld cause this problem but it sounds like the 
dll file is write protected or it is in use by IIS. I know that IIS 
shouldn't lock any DLL files but I have noticed that so can happended in 
some cases.

You are compiling a dll inside your web application. Make sure you have 
the bin folder in the root of your web app.

Philip,

Thanks again for your response. I realized that the command in the batch 
file was expecting a bin sub-folder which I hadn't added yet. I have since 
done so and am now over that hump but am getting a long list of compile 
errors much like those reported by someone else a few days ago.

The first compile error is:

"error BC32017: Comma, ')', or a valid expression continuation expected"

on the 2nd line of code shown below

    Dim ds As New DataSet()
    ds.ReadXml(ctx.Server.MapPath(""pizzas.xml""))

Just curious. Have you gone through the Pretty Quick Pizza exercise in 
the "Inside ASP.NET Web Matrix" book or know of anyone who has?

Haven't gone through PQP but I did finally realize that the Web Service 
template I was trying to use (see my earlier post) has a mixture of VB and 
C# code!  Doesn't compile, of course.  I don't know C# so it wasn't 
obvious to me at first.  Apparently template wasn't tested before 
releasing WM. Don't know if that's one of the problems you're running into 
but it may be a clue....

I am happy to report that I finally got my DataLayer.vb class to compile 
into a dll with no errors. But I had to cheat to do it! I downloaded the 
sample files from http://www.AlAndDave.com/books/webmatrix/ and took a 
look at their DataLayer.vb file. It seems that there is some sort of mis-
print in the book: all of the places where there are 2 double-quote 
characters ("") should be just one double-quote ("). Having 2 double-
quotes together did look sort of weird to me. I went back to my own 
DataLayer.vb and changed all those "" to " and it compiled OK.

Thanks for that, I was the one who had the compiling probs a few days back
and still hadn't found the error.

I also had to change the listing to use the cmd.Parameters.add when writing
the order row, Is this a typo in the book or have I missed something.

Rod,

Did you have to make this change (from cmd.Parameters to 
cmd.Parameters.Add) to get the DataLayer.vb class to compile or to run 
correctly? I haven't gotten to the point where I can test the class yet, 
maybe today.

Stan

Stan,
Just to compile, I haven't tested it either.
Let me know how you go.
