Exception Thrown When Running From Command Line

darryl_staflund

Hi Red Gate,

Congratulations on the release of Exception Hunter. It looks like a great product and is really quite innovative -- I haven't heard of a similar tool.

I tried running Exception Handler from the command-line on an application I am developing and received the following exception (NB: Here's the command-line output of my run):

C:\Work\wm\build>"c:\Program Files\Red Gate\Exception Hunter 1\Hunt.exe" /assembly:".\<MyAppHere>.exe" /all /warnOnlyOnMissingReference:on
Exception Hunter Command Line V1.0.0.551

Other than this particular exception, I have been able to run Exception Hunter no problem.

Hi Darryl,

We have identified a potential problem in the handling of missing dependent assemblies in the command-line version of Exception Hunter, which will be fixed in a future release.

In the meantime, the program should work without error if you specify the path to the missing assembly in the searchPaths argument:

Hunt.exe" /assembly:".\<MyAppHere>.exe" /all /searchPaths:<pathToActiveReports.chart> /warnOnlyOnMissingReference:on

We're sorry for the inconvenience.

I'm currently evaluating EH and am getting the same exceptions from command line that Darryl is. However, I've tried setting the search paths (I run out of my assembly's bin directory as well) to include as many locations as I can come up with, but the error still appears. Is there some way to determine which dependent assembly is causing the issue?

BTW, this is the full line I'm currently executing (I've got another one with bin\debug paths to every reference in the project, separated by commas):
C:\DEV2\LOSSMIT\WebSite\bin>"C:\Program Files\Red Gate\Exception Hunter1\Hunt.exe" /assembly:elmsbl.dll /all /warnOnlyOnMissingReference:on /searchPaths:"C:\Program Files\Microsoft Visual Studio 8\ReportViewer","C:\dev2\LossMit\WebSite\bin" /exceptionReport:true

Hi,

You may want to try the latest private build of Exception Hunter 1.1. It has some improved reading of assembly metadata:

Unfortunately, EH 1.1 gives me the same error.

Brian Donahue

Just to clarify, are you getting the warning about not being able to locate the assembly or the error about not being able to analyze a method?

If you can't analyze a method, it may just be that the assembly, or one of its' dependencies, was built using an obfuscator. These can make it difficult or impossible for Exception Hunter to disassemble the code (essectially that's their job!) and there may not be a way of analyzing this dll without getting a version that isn't obfuscated.

It's an error (happens very late in the process, but the exception report isn't generated):
