Wine, WineLib and "Programming Windows 95"

2.13.1. Chapter 15 - devcaps2

Last updated: 2003/5/4

Description

This is similar to devcaps1 but displays extra device characteristics for either the screen or the selected printer.

Wine tests

I don't have a printer installed so I could only test it on the screen.

In the 'base information' list I noted some differences in the results for:

Item	Windows	Wine
BITSPERPIXEL	32	24
COLORRES	24	0
PDEVICESIZE	240	0
DRIVERVERSION	0400H	0300H
CP_RECTANGLE	Yes	No
RC_BANDING	No	Yes
RC_SCALING	No	Yes

There are many other differences in the 'curves', 'lines', 'polygons' and 'text' sections. Sometimes Wine claims to have way more capabilities than the Windows driver. Is that really true?

Winelib tests

Same as with Wine.

2.13.2. Chapter 15 - formfeed

Last updated: 2003/5/4

Description

Sends a formfeed to the printer.

Wine tests

I don't have a printer installed so I cannot check that this really worked.
Worked just like on Windows for me.

Winelib tests

Same as with Wine.

2.13.3. Chapter 15 - poppad

Last updated: 2003/5/4

Description

Adds printing functionality to the poppad example.

Wine tests

For other problems, see the poppad3 example in chapter 11.

Winelib tests

poppad.c is incorrect. It uses NULL where we should really have a '0', thus this compilation warning (same as on Windows). Since it's just warnings it does not warrant a patch, we can just ignore them:

poppad.c: In function `WndProc':
poppad.c:373: warning: passing arg 3 of `SendMessageA' makes integer from pointer without a cast
poppad.c:380: warning: passing arg 3 of `SendMessageA' makes integer from pointer without a cast
poppad.c:391: warning: passing arg 3 of `SendMessageA' makes integer from pointer without a cast

When the print dialog box is displayed I get the following messages:

err:commdlg:COMMDLG_DllEntryPoint commdlg.dll instantiated twice!
err:commdlg:COMMDLG_DllEntryPoint commdlg.dll instantiated twice!
err:commdlg:COMMDLG_DllEntryPoint commdlg.dll instantiated twice!

Then when I choose 'Ok' I get:

fixme:commdlg:PRINTDLG_UpdatePrintDlg Collate lppd not yet implemented as output

Printing does nothing. That's because I don't have a printer and printing is disabled anyway, as the following message tells me:
```
Printing disabled in wine.conf or .winerc file
Use "printer=on" in the "[wine]" section to enable it.
    
```

2.13.4. Chapter 15 - print1

Last updated: 2003/5/4

Description

Prints a demonstration graphic on the default printer. This graphic is also shown in the program's window.

Wine tests

I don't have a printer installed so I cannot check that this really worked.
This program adds a 'print' entry in the system menu so you must run it in unmanaged mode to be able to really test it.
Starting the print says that printing is impossible which is logical since there is no printer installed in my setup.
