(PureBasic) Using DebugLogFilePath to Debug a Crash

If a crash is suspected to occur within a Chilkat method call, it can be debugged using the VerboseLogging and DebugLogFilePath as shown here.

Procedure ChilkatExample()

    ; If a crash is suspected to occur within a Chilkat method call, it can be debugged using the VerboseLogging and DebugLogFilePath as shown here.
    ; 
    ; NOTE: The same technique applies for any Chilkat class that has the DebugLogFilePath property.
    ; Most Chilkat classes have DebugLogFilePath.

    crypt.i = CkCrypt2::ckCreate()
    If crypt.i = 0
        Debug "Failed to create object."
        ProcedureReturn
    EndIf

    ; First make sure VerboseLogging is turned on.
    CkCrypt2::setCkVerboseLogging(crypt, 1)

    ; Set the DebugLogFilePath to the path of a log file that will be created automatically.
    ; If the file already exists, Chilkat will append to it.
    CkCrypt2::setCkDebugLogFilePath(crypt, "c:/someDir/debugLog.txt")

    ; Reproduce the problem.

    ; ...
    success.i = CkCrypt2::ckVerifyP7M(crypt,"c:/someDir/someFile.p7m")
    ; ...

    ; If a crash occurred within Chilkat, then the debugLog.txt will contain information that
    ; can be sent to support@chilkatsoft.com

    ; ------------------------------------------------------------------------------------------------
    ; Note: Given that the debug log file is always appended, the log file might grow 
    ; to a very large size.  You can prevent the continual growth of the log file by
    ; deleting the log file at certain points, such as after a Chilkat method returns.
    ; 
    ; Given that we're only interested in the log file for Chilkat calls that crash or hang,
    ; it's OK to delete the log file after a Chilkat method that returns.
    ; 
    ; The next call to a Chilkat method will re-create the log file.  If the Chilkat call crashes
    ; or hangs, then you'll be left with just the log of the crash or hang.
