WebLauncher ObjectModel problems
 

I'm trying to adapt the WebLauncher project to a build project I've set up. I'm using Visual Studio 2008 and just playing around in a debug environment. Using the sample code for BuildWithConsoleApp I'm able to run my VBP just fine. When I try to use the sample code for BuildWithObjectModel (I'd like to be able to easily view build progress in the browser), however -- I get an "Access violation" exception:

Source Error:

Line 144: VisBuildSvr.Builder bld = new VisBuildSvr.BuilderClass();

The .BLD is unimportant. I know the BLD project works fine (and in fact works fine when building via the GUI, CLI, or ConsoleApp method in the sample project), so any BLD should be fine.

There is no build log because it doesn't get to actually running the build. It fails on the app.Project.Load(projectFile) call with an Access Violation exception.

Try copying

C:\Program Files\VisBuildPro7\Samples\User Actions\NETAction\bin\Debug\Interop.VisBuildSvr.dl l

to

C:\Program Files\VisBuildPro7\Samples\Misc\WebLauncher\Bin\

That seems to have fixed it. Any particular reason for those DLLs to be different?

Also... Is there a way to serve up the status of a build in (pseudo) real-time? The WebLauncher sample seems to just dump all the output after the process completes - which makes the progress events seem kind of pointless (in a web environment)

Ultimately, I'd like to be able to have a page that can get the current status of a running continuous integration type setup, although I can presumably do that by dumping out status info to disk periodically and having a web page read that information.

We goofed up and didn't get that DLL updated to the final version. It's fixed now in the latest download at http://www.kinook.com/Download/VisBuildProEval.exe

Add a Response.Flush() call after Response.Write() in the step events.
