Code: Select all
#include "ComObj.hpp"
#include "GdPicture_NET_9_TLB.h"
void unlock()
{
_LicenseManagerPtr oLicenseManager;
oLicenseManager = (_LicenseManagerPtr)CreateComObject(CLSID_LicenseManager);
BSTR bstrTest = ::SysAllocString(L"YOUR_LICENSE_KEY");
oLicenseManager->RegisterKEY(bstrTest);
::SysFreeString(bstrTest);
bstrTest = NULL;
}
/!\ In addition, in the main form constructor (OnCreate event) you need to add these two lines, otherwise you could have errors such as div by 0 due to differences between Borland/Embarcadero and Microsoft compilers :
Code: Select all
#include <WTypes.h>
Set8087CW(0x133f);
To import the SDK in the ActiveX Palette: Components / Import Component... / Import ActiveX Control / Select GdPicture.NET / select Generate Component Wrappers / Install to a new Package / use GdPicture as package name / Finish.
If you have any question just let reply this ticket!

C++ Builder has a type for COM object communication: OleStr. No need to allocate and free buffers for every string passed into the GdPicture components.
Drop the TLicenseManager control on a form (here named LicenseManager)
Code: Select all
#include <GdPicture_NET_12_TLB.h>
bool unlock(void) {
return LicenseManager->RegisterKEY(OleStr(L"YOUR_LICENSE_KEY").c_bstr());
}
returns true on success.
