Viewing the DLL debug information

 

If you are having problems collecting thread data for a particular EXE/DLL the problem may be that the debug information that is required to perform the instrumentation of the software cannot be found.

 

You can view a list of the debug information status of modules loaded by your target application.

 

Tools menu DLL Debug Information... shows the DLL Debug Information dialog below

 

 

The dialog shows:

 

•the path from which Modules (DLL or EXE) were loaded
 

•the debug Status (below)

 

 

Debug status

 

There are various reasons why a module may not have its debug information read.

 

The dialog shows a comment or reason in the status column. Examples might be:

 

•PDB or MAP if the debug information was found and used
 

•Debug information not present

 

 The status column may contain a button to enable you to find out more via the Debug Information Diagnosis dialog
 

•A reason for being ignored
 

•Module is a part of the C Run-time Library (CRT) or Standard Template Library (STL)
 

•Location is a system directory
 

•Ignored due to Hooked DLLs advanced settings
 

•File is a Software Verify own module
 

•Module has been specified as a 3rd party
 

•No executable code is contained
 

•The module only has GUI resources
