[gme-users] Help with paradigm registration

[Peter Volgyesi]

Hi,

1., Create a new Win32 Console Application (Choose simple application)

2., Add MgaUtil.idl, Mga.idl and Meta.idl to your project (right click on
Source Files, select Add Files to Folder... and find these files in the
Interfaces folder of the GME installation)

3., Open Project/Settings...

4., In the Settings For: combolist select "All configurations"

5., For each .idl files you've just added set the Custom Build parameters:
    a., Command textbox: midl $(InputPath) /server none /client none
/IC:\Program Files\GME\Interfaces
    b., Outputs textbox: .\$(InputName).h

6., In your .cpp file include the following files (right after stdafx.h):
    #include <objbase.h>
    #include "mgautil.h"

7., Here comes the contents of the main function:
------------------------------------------------------
int main(int argc, char* argv[])
{
	HRESULT hr;
	CLSID clsid;
	IMgaRegistrar *reg;

	//Initialize the OLE libraries
	hr = ::CoInitialize(NULL);
	if (FAILED(hr)) {
		// TODO: error handling
	}

	hr = ::CLSIDFromProgID(OLESTR("Mga.MgaRegistrar"), &clsid);
	if (FAILED(hr)) {
		// TODO: error handling
	}

	hr = ::CoCreateInstance(clsid, NULL, CLSCTX_ALL, 
		__uuidof(IMgaRegistrar),reinterpret_cast<void**>(&reg));
	if (FAILED(hr)) {
		// TODO: error handling
	}
	
	BSTR connstr = ::SysAllocString(OLESTR("XML=C:\\Temp\\foo.xmp"));
	BSTR parname = NULL;

	hr = reg->RegisterParadigmFromData(connstr, &parname,
REGACCESS_SYSTEM);
	if (FAILED(hr)) {
		// TODO: error handling
	}
	::SysFreeString(connstr);
	::SysFreeString(parname);


	reg->Release();

	::CoUninitialize(); 

	return 0;
}
------------------------------------------------------

Hope, this helps.
