Hello!

My problem today is tricky....

evertytime i activate the plugin i want to send a commad to VDJ to clone the deck.

And now:

SendCommand("clone_deck 3",1);
does not work.

This one works:
SendCommand("clone_deck",1);

Everytime if i want to send an action with a space between, the send command does not work.

How can i get this fixed?

Best regards, C.Hackl

What value are you returning for rclsid in DllGetClassObject?

Since it is my first VDJ plugin, i have to tell you, that i don't know where to put it to the code and what value I have to take :(
I've read the SDK, serached all on google and the VDJ site.... but there are still questions i have and one of them ist that.

But i dont whant to ask evry silly question, i want to learn it on my own :P - and i hop i'll get that :D

Would you be so kind to help me with that DllGetClassObject / SendCommand thing?

Best regards, C.Hackl

i'm using the layouts of microsoft visual studio 2008 that i've found here at the page and this shows me this:

HRESULT VDJ_API DllGetClassObject(const GUID &rclsid,const GUID &riid,void** ppObject)
{
// This is the standard DLL loader for COM object.
// You don't need to change anything in this function.
if(memcmp(&rclsid,&CLSID_VdjPlugin,sizeof(GUID))!=0) return CLASS_E_CLASSNOTAVAILABLE;
if(memcmp(&riid,&IID_IVdjPluginDsp,sizeof(GUID))!=0) return CLASS_E_CLASSNOTAVAILABLE;
*ppObject=new Cslipmode();
return NO_ERROR;

Or do i have to change something?

That means you are using the v5 SDK, hence the old SendCommand format.

If you use the latest SDK from here:

http://www.virtualdj.com/wiki/Developers.html

And use: if(memcmp(&rclsid,&CLSID_VdjPlugin6,sizeof(GUID))!=0) return CLASS_E_CLASSNOTAVAILABLE;

This means you can then use VDJScript commands.

Ok i've downloadet and saved all those files to the SDK.

But now i get a lot of Errors in the Basic Plugin where i want to write the code. Is there any basic plugin coder for the SDK V6?

Ok at the moment i get an error here:

VdjPlugin.h:
//////////////////////////////////////////////////////////////////////////

}
#endif
#endif


This is the initalisation in the plugin:
HRESULT __stdcall DllGetClassObject(const GUID &rclsid,const GUID &riid,void** ppObject)
{
	// This is the standard DLL loader for COM object.
	// You don't need to change anything in this function.
	if(memcmp(&rclsid,&CLSID_VdjPlugin6,sizeof(GUID))!=0) return CLASS_E_CLASSNOTAVAILABLE;
	if(memcmp(&riid,&IID_IVdjPluginDsp,sizeof(GUID))!=0) return CLASS_E_CLASSNOTAVAILABLE;
	*ppObject=new Cmy_plugin4();
	return NO_ERROR;
}


Vistual Studio tells me:
error C2375: 'DllGetClassObject': Newdeffinition, different attachment

It tells me a mistake at the deklaration od an "DllGetClassObject"

That'll sort it - #define WIN32_LEAN_AND_MEAN :)

Big thanks man!

Would it be possible to update the SDK for Visual Studio 2008, so that you are able to load a effectlayout if you start it?

I got now all and i exported a working effekt. But till a releas it will take some time, that i can get clear with c++. I just learnd Visual Basic at scool an c++ is a bit different :P

Thanks for help,
Regards, C.hackl
