Can anyone tell me why the demo liscense for GDTwain will not work for Borland C++ builder 4.0? I ran the sample code for VB and it worked fine for it. I tried using the function mbstowcs to convert a string of characters to a wide string but still not working?????
Thanks,
Boom

Hi,
The
SetLicenseNumber() method are waiting for an unicode string parameter.
Check you are passing the string key into Unicode format.
IE:
Code: Select all
this->GdViewer1->SetLicenseNumber( (wchar_t *) "LicenseKey");

Hi,
I tried the line of code you recommended but when executing it an exception was raised "External exception C0000029". Any ideas why this exception would be raised?
Thanks,

Hi Boom,
This this instead. It is working in BC++ 5, I suggest it will be ok for BC++ 4 too...
Code: Select all
WideString LicenseKey = "YourLicenseKEY";
this->GdViewer1->SetLicenseNumber(LicenseKey);
