Hi,
I am calling WcaGetProperty multiple times like so:
hr = WcaGetProperty(L"ANALOG_INPUT",&szAnalogInput);
ExitOnFailure(hr, "failed to get the number of channels");
strcpy(szChannelInfo, "ANALOG_INPUT");
ReadChannelInfo(hInstall, szChannelInfo, szAnalogInput);
hr = WcaGetProperty(L"DIGITAL_INPUT",&szDigitalInput);
ExitOnFailure(hr, "failed to get the number of channels");
strcpy(szChannelInfo, "DIGITAL_INPUT");
ReadChannelInfo(hInstall, szChannelInfo, szDigitalInput);
hr = WcaGetProperty(L"ANALOGO_OUTPUT",&szAnalogOutput);
ExitOnFailure(hr, "failed to get the number of channels");
strcpy(szChannelInfo, "ANALOG_OUTPUT");
ReadChannelInfo(hInstall, szChannelInfo, szAnalogOutput);
Although the first call works fine but the second one returns Invalid
Handle, I have no idea what is happening as I have done this before without
any problems. Any ideas?
Kind Regards,
Natalie Carr
