Accessing compiler error messages from web page that runs batch file


J

Jon Maz

Hi All,

To allow myself to make development changes directly on a remote server
*without* having to compile on my local dev machine and then upload the
dll's to remote, I have created a RunBatch.aspx on the remote which calls a
batch file (myBuild.bat) on the same machine, and this batch file executes
the necessary command-line compiler instructions to recompile (code below).

So far (fingers crossed) it seems to be working. The only thing I'm
missing, but would really like access to, is any compiler error messages
that may arise. Does anyone have any ideas how RunBatch.aspx could get hold
of those error messages from csc.exe (or from cmd.exe, I'm not actually
entirely sure where they are), and print those out to the screen?

Thanks!

JON

PS No Visual Studio in this setup, before anyone asks!

**************
RunBatch.aspx
**************

Process myProcess = new Process();
myProcess.EnableRaisingEvents = true;
myProcess.StartInfo.FileName = @"c:\Inetpub\wwwroot\myBuild.bat";
myProcess.StartInfo.WorkingDirectory = "C:/";
myProcess.StartInfo.Arguments = "file.txt -s -m";
myProcess.Start();
myProcess.WaitForExit();
Response.Write("myProcess.ExitCode: " + myProcess.ExitCode + "<br>");

Jon,

You can use the Compiler class in the Microsoft.CSharp namespace. You
can set a reference to cscompmgd.dll, and then access it programatically.

It should be noted that this will be marked as Obsolete in .NET 2.0.
I'm not sure what replaces it (although I am sure there will be something).

Hope this helps.

Hi Nicholas,

Thanks for the tip, that's something new for me, I'll look into that
tomorrow from work.

If anyone has any relevant code samples or url's, it'll be much appreciated!

Cheers,

JON
