Topic: I could use some help with GetInfo()

This topic is old and might contain outdated or incorrect information.

I'm writing a custom mapper and I have a little problem:

I call GetInfo to get various int values. Everything works as it should!

But if I call GetInfo to get char* values while it works fine in runtime, when I try to close the app it hungs...

Can anyone help me please?

I've not had that problem, any chance of a sample of how you're declaring, calling and using?

Regards,

Among other parts of code I will post only the parts that matter...


class PhantomDj : public IVdjPluginDevice
{
public:
char ArtistA[36]; char ArtistB[36]; char TitleA[36]; char TitleB[36];
HRESULT hrs;}

HRESULT __stdcall PhantomDj::OnTimer()
{
if (DeckInfo[0]->Status>0){
hrs=GetInfo("Author 1",&ArtistA);
SetText(0,DENON4500_TEXT_LINE1,ArtistA);}
}

ULONG __stdcall PhantomDj::Release()
{
return S_OK;
}

On the Release I also tried delete
ULONG __stdcall PhantomDj::Release()
{
delete this;
return 0;
}

With no success

As I said, it works fine during runtime.... It hangs the app when I try to exit so I believe it has something to do with the destructor...
If I don't use GetInfo to get ArtistA everything works fine... Also I don't experience any issues when I read int values ..

PS: My C++ knowledge is very limited... I'm mostly a VB programmer... I just write this mapper while I try to learn the basics on the same time....

use:

char ArtistA[512]="";
GetInfo("Author 1",ArtistA);

ArtistA is already a pointer
( <=> char *ArstistA=new char[512]; )
