MalformedURLException
I am trying to parse an xml file that resides on my local machine. If i
try sending in the path of the file to the Parser I get an
MalformedURLException
I have tried passing the file name as" file:C:/wf32/personal.xml " the
parser object but I get a RuntimeException error . This is the same xml
file that came with the samples
so I am sure the problem is not with the file. BTW I am using Borland
C++5 on Windows98. Any help will be appreciated
A few lines of the code are as follows:
char * fileName = "file:C:/wf32/personal.xml"
DOMParser *parser = new DOMParser;
// Parse the XML file, catching any XML exceptions that might
propogate
// out of it.
//
bool errorsOccured = false;
try
{
parser->parse(fileName);
int errorCount = parser->getErrorCount();
if (errorCount > 0)
errorsOccured = true;
}
catch (const XMLException& e)
{
}

Replace file: with file:/// in the local url. Note the 3 slashes!

No problem - just instrument the final EXE using your DLL.
Note that "minmal" instrumentation occurs when you don't have any
debug info available for a module (be it DLL or EXE) - you should get
"precise" instrumentation with your DLL. If you set your project to
use program database debug information, i.e. external ".PDB"-files,
you must copy these to the location of you DLL in order for purify to
pick up the information.
That's all you need to purify Xerces-C or any DLL using it.
Please check the purify help for additional info, e.g. how to tune
which level of instrumentation you want for individual modules in your
project etc.
If you get warnings about "freeing invalid memory" etc. when using
Xerces-C, make sure you link with the same runtime library as Xerces-C
(/MDd for debug exe files and /MDd /LDd for debug DLL files). Check
the Xerces-C FAQ on the website for some background info on this.
Regards,
Martin

We use NuMega Boundchecker to detect memory leaks. It still need an exe to
work. But that is no problem. You still need code to drive the tests. Just
load the dll and perform tests. It should work the same way with purify.

Hi.
I must thank Martin for the answer, but I've got a problem:
I'm not developing an EXE file, but a DLL.
So my 'very short' Purify Report is:
*****************************
Instrumenting:
myfile.dll 499762 bytes
*****************************
Is not there any way to detect memory leaks within a DLL?
regards.

NB that Purify will not provide any profiling/optimization hints, but
it will detect memory leaks, buffer under-/overruns, invalid pointer
reads etc.
As Herb Chong pointed out, Purify should integrate with VC++ at
install time and give you some handy toolbar buttons that you can use
in Visual Studio.
If you want to go for the command-line option, make sure you have the
purify install- and cache directories in your path (normally SET
PATH=%PATH%;C:\progra~1\rational\purify;C:\progra~1\rational\purify\ca
che) and run:
# (your nmake line)
# purify /replace=yes /run=no myexecutable.exe
This will replace your executable with an instrumented version that
will load the Purify GUI at start-up.
Good luck,
Martin.

Memory Profiler
Posted by Xerces Rule <xe...@bilbao.com>.
Hi!
I'm creating a program by using:
nmake /f "my_makefile.mak" CFG "my_program - Release"
(Using VC++6.0 on Windows NT4.0)
Now, I want to optimize the memory using by my program, and
I've
downloaded 'Rational Purify', in order to test it.
Does anybody know how to modify my 'makefile' in order to
use
'Rational Purify'?
Does anybody know a better way to 'purify' my program?
Regards and thanks.
