Converting Delphi 5 code to Delphi 2010 Code Part III ?

I am converting Delphi 5 code over to Delphi 2010 code.


Question 1:

I get the following error:

There is no overloaded version of 'DocumentProperties' that can be called with these arguments

on this call:

ExtDevCode := DocumentProperties (0, DrvHandle, FDevice,
                                      FDeviceMode^, FDeviceMode^,
                                      DM_IN_BUFFER or DM_UPDATE);

:

DrvHandle:    THandle;
FDevice:     PChar;
FDeviceMode: PDeviceModeA;


Question 2:


I get the following error:


Incompatible types: 'PDeviceModeW' and 'PDeviceModeA' (PDiviceModeA from windows.pas)

on the following call:

FNumBins := DeviceCapabilities (FDevice, FPort, DC_Bins,
                                     nil, FDeviceMode);


    FDeviceMode: PDeviceModeA;
