This is awesome!

Alway up for a 16bit Windows mini game. Sudoku is nice. Look and feel is clean and blends in with Windows original games. Thank you for this.

Here are some things I noticed:
1. vb40016.dll required to play. If this dll could be distributed with the game that would make it more accessible.
2. Windows 3.x runs at 640x480 by default. Your game needs 1024x768 or higher.
3. Here are some things that could be added:
1. A pause function.
2. The minimize button on the window enabled.
3. Brief instructions on how to enter the numbers into the squares.

Otherwise, nice job!

I am curious about the source code but I am guessing you don't want to publish that, right?

No resizing window. It does not even fit to 640x480. And it needs OLE2 runtimes and newest TYPELIB.DLL. I got mine from Windows 95. Original Windows 3.1 OLE2 runtime one says that it is too old for this program. Or why so much whitespace.

It seems iceblade has disappeared. No new posts whatsoever. Too bad, I thought this sudoku project was interesting.

It's only been a month...

unfortunately vbdis4 can't decompile it.

Some programs like this would scale/stretch everything to fit the window allowing everything from CGA to supervga to work.

Usually could go back to 1:1 with sliders to view the whole screen pan and scan as well

In the case of Windows 3.11 CGA support seems unnecessary. I don't think Windows 3.11 even supports CGA. Not by default at least. I believe Windows 3.0 could be coerced to use CGA. If Iceblade wants to he could probably get his Soduku game to work on Windows 3.0 with some refactoing or tweak to the system. (I haven't confirmed or tested any of these claims btw, they're just my personal thought about the manner.)

these drivers are released in WDL in Microsoft TechNet Software Library:
https://archive.org/download/technet-sw-libra … 1999/EGA311.EXE
https://archive.org/download/technet-sw-libra … pt-1999/CGA.EXE

So there were drivers for CGA/EGA for 3.11. Interesting. I couldn't think of any plausible scenario where those would be useful. Assuming a pre-VGA 80386 from the late 80's it probably couldn't run Windows 3.11 without serious upgrades. Unless you updated the videocard as well you'd have some weirdly inbalanced system that couldn't take full advantage of the other upgrades (ram/hdd) anyway.

So does anyone know of a case where Windows 3.11 in CGA or EGA makes sense?

Neighbor had a CGA Compaq 286 laptop that ran “normal “ not workgroups with 5mb and CGA.

The pain was that microshaft didn’t explain how to swap in the correct system fonts for CGA to look correct.

His father managed to then pick up some sort of 386 portable that again didn’t have drivers for it’s proprietary display forcing him to use CGA with WFW 3.11

In the portable PC world they were still selling new machines that had some sort of mono-not vga or in many cases not EGA graphics device well into 1992. These things “may” have had a 16 grayscale 640x400 display which was great for dos text but had a proprietary graphics mode that nobody supported which dropped you back to CGA.

While I can see how some people need them, those old laptops were terrible imho. Yeah, I guess such cases would warrant a CGA driver for Windows. Was there anything useful for Windows that worked on such a configuration?

EDIT:
(typo)

Sorry for the silence — I’ve been busy lately.
I’ll continue the Sudoku updates as soon as I’m able.

I wonder if you will make source code available later?

Sure

Depends on what you define "useful". Games that are playable on CGA? I've gone through the trouble of identifying several that I personally deem as playable:

Utilities? Unless they explicitly disallowed to run based on the colour depth and/or resolution of the desktop, you can theoretically run anything. Paint Shop Pro v2.01 runs without issues, same with MegaEdit and Windows/Total Commander.

Besides the more mediocre than necessary graphics device these laptops were more or less identical to their then current desktop counterparts and ran all the things, excluding CD media and vga dos games. (Only one of my friends had a cdrom in 1992)
So office or MSWORKS (matching the cpu) both ran fine. Most all windows programs worked ok as well but you might need to pan and scan some that didn’t fit vertically.

My friends laptops both had more ram than my new but underpowered desktop pc in that same era but I had vga and better sound.

I believe he even accessed one of the early monolithic “web services “ on his laptops.
