Feasible to use GUI support from ReactOS or WINE? (DOSX)

Is it possible to use gdi32.dll and user32.dll from ReactOS or WINE project? So that it will have full support of Win32 GUI programs.

Since current gdi32.dll is using vesa32.dll. Maybe there're modifications in the original gdi32.dll.

I think the GUI support is a complicated task. So re-implementing it totally in assembly is not a good idea.

:confused:

A reason, why every DOS-only GUI have had no chance...

NO. Most of the buggy GUI's are buggy because of C and Allegro, rather than ASM ... havent yet seen a buggy GUI written in ASM. :no:

I didn't try yet. The Wine license is LGPL, so this most likely might allow to use them. If the Wine GDI32 totally relies upon KERNEL32 and DDRAW and doesn't make usage of any Unix APIs, it might be "almost" trivial to reuse it for HX. However, I'm afraid the size of hxrt will increase dramatically.

yes, but there is no further reimplementation planned at all.

With an extra download this would be no problem...

I checked the Wine and ReactOS Win32 modules: the ReactOS modules are true Win32 dlls (of course), but they import lots of ntdll.dll. GDI32 is not based on DDRAW.DLL, it speaks directly with the display driver, which makes it unusable for HX. More interesting is USER32.DLL (file size 1.2 MB), but it still would require many adjustments, because it imports lots of stuff from ntdll.dll.

IMO it is more promising to improve HX's qemu support, build a DOS version of kqemu (allowing to run userland code natively) and then run ReactOS (and possibly FireFox on ReactOS :) ) in DOS-Qemu.

I may have lost a point here :
what's the use of running ReactOS in DOS-Qemu, as opposed to running it natively ?

I don't know. Possibly you should ask the people who make things like Qemu, VPC, VMware, ...

I think the question is: "Why running this in DOS?" If you have no task management in DOS it is useless?!

A missing task switcher (in DOS) makes things worse, but not useless.

if a VM's state can be quickly saved and restored, there's no difference compared to running java/.net applications.

Obviously you haven't actually tried running ReactOS. I tried on two different computers and it wouldn't even boot on either ("alpha" software, ya know). :P

So yeah, if you could get ReactOS to consistently work for everybody, that would be a good thing. (Plus, if it crashes in a VM, no worries right?)

That's a pity: some applications require AngleArc, Chord, CreateHatchBrush, PolyBezier, PolyPolygon, RoundRect. May you just add "stubs" (aka dummies) for them? Also HX-DOS cannot launch FAR 1.70: it requires DefineDOSDeviceA?

Your nice DOS extender definetly lacks one options: "run program with some unresolved imports". Unresolved imports may be setted on the stub which prints "Unresolved import ****. System halted".

this option is implemented already: set DPMILDR=128.

it doesn't display a message yet, but if you think it's necessary, one can implement it, that's no big deal.

Would be good :-)

BLAH.EXE called ignored missing import EncodePointer, aborting.

Also, the messages displayed by DPMILD32 are not always informative, there is space for improvement:

Missing DLL: NTDLL.DLL required by GLUE32.DLL
Missing import: DoJunk required by BLAH.EXE missing in DKRNL32.DLL

Should be:

BLAH.EXE called ignored missing import EncodePointer in DKRNL32.DLL, aborting.

3 things are guilty about one missing import :-|

Message will be "DPMILD32: unresolved import called", followed by an "int 3", (which should cause an DKRNL32 register dump if this dll is loaded), and at last an int 21h, ah=4Ch.

How to find out the name then ?

That's by design and nothing to worry about. (Default value was much smaller.)

Would be good ... + MSVCRT.DLL GLUE32.DLL OPENGL32.DLL ASPI.DLL ...

OTOH:

- DGDI32.DLL is highly DOS / VESA specific
- The missing NTDLL imports

Not amused that much :-|

You don't give up DOS ... you can kill QEMU within 1 second and are in DOS ;-)
Also, NT-specific virii can't damage your DOS installation.

Disagree :no: DOS is very useful without the "task" troubles ;-)

I can ... but don't whine about abusive increasing of post count this way then :crying:
