initialized myservices?
initialized myservices?
i initialize api of the following way:
code:
//create a custom services instance.
odstaticrxobject<myservices> svcs_;
//inicializamos dwgdirect
boost::format berr ("\nerror al inicializar directdwg: %1%");
try
{
odinitialize(&svcs_);
} catch (const oderror& e)
{
berr % berr % svcs_.geterrordescription(e.code());
std::cout << berr.str().c_str() << std::endl;
return false;
}
have some way to know if api this already initialized?
with svcs i can know if this initialized?
sorry for my english
great calvet
there is no direct way.
you may use this workaround:
code:
bool isddinitialized()
{
try
{
::odrxsystemservices();
return true;
}
catch(oderror& e)
{
return false;
}
}
odrxsystemservices will throw oderror(enotinitializedyet) if dd is not initialized.
(btw, there is nothing wrong with second initialization - it will just increase internal refcounter)

the error happens when reading for the second time .dwg in the following call...
code:
return readfile(odsystemservices()->createfile(filename, ndesiredaccess, sharemode),
allowcpconversion, partialload, password);
some idea the reason for this exception?
thx calvet

what kind of error?
can it be reproduced in our samples?

i have this console application...
code:
// directiniterror.cpp: define el punto de entrada de la aplicaci髇 de consola.
#include "stdafx.h"
#include <odacommon.h>
#include <dbdatabase.h>
#include <dbblockreference.h>
#include <exservices/exsystemservices.h>
#include <exservices/exhostappservices.h>
#include <exservices/odfilebuf.h>
#include "dwgapp.h"
int _tmain(int argc, _tchar* argv[])
{
{
std::string str("d:/aplic/b14_sg/resources/circle.dwg");
dwgapp app;
app.launch();
if (!app.loaddocument(str))
{
return false;
}
app.quit();
}
{
std::string str("d:/aplic/b14_sg/resources/line.dwg");
dwgapp app;
app.launch();
//the error be produced in this moment
if (!app.loaddocument(str))
{
return false;
}
app.quit();
}
}
whit this class:
code:
#include <dbblockreference.h>
#include <exservices/exsystemservices.h>
#include <exservices/exhostappservices.h>
#include <exservices/odfilebuf.h>
class myservices : public exsystemservices, public exhostappservices
{
protected:
odrx_using_heap_operators(exsystemservices);
private:
#ifdef _msc_ver
bool getpassword(const odstring& dwgname, bool /*isxref*/, odpassword& password)
{
return true;
}
#endif
};
class dwgapp
{
public:
virtual bool launch();
virtual void quit();
bool loaddocument(const std::string& docpath);
private:
odstaticrxobject<myservices> svcs_;
oddbdatabaseptr pdbdocument_;
};
#endif
implementation:
code:
#include "stdafx.h"
#include "dwgapp.h"
bool dwgapp::launch()
{
try
{
odinitialize(&svcs_);
} catch (const oderror& e)
{
return false;
}
return true;
}
void dwgapp::quit()
{
svcs_.release();
}
bool dwgapp::loaddocument(const std::string& docpath)
{
odstring oddocpath (docpath .c_str());
try
{
pdbdocument_ = svcs_.readfile(oddocpath, true, false, oda::ksharedenyno);
return true;
}
catch (const oderror& e)
{
}
return false;
}
you should either call oduninitialize in quit(), or not destroy services object

thanks to answer so fast. i put the function "oduninitialize();" in my method "quit", but with this the applicati髇 try the exception when the application leaves the first method.
code:
{
std::string str("d:/aplic/b14_sg/resources/circle.dwg");
dwgapp app;
app.launch();
if (!app.loaddocument(str))
{
return false;
}
app.quit();
//in this point try the exception
}
the exception is sent by oddbdatabase when it destroys smartpointer...
in order to solve i have removed it oddbdatabase from the class and i have passed it through parameter to the loaddocument method
thanks from spain...
