User contributions / Offline GitHub MS Documents

Last post by John Z - November 09, 2025, 05:21:33 PM

Attached is the full release for the access program for the win32-docs.zip downloaded from GitHub:
https://github.com/MicrosoftDocs/win32

This provides a way to use and access documentation (mainly the API Names) from the GitHub documentation effort off-line, and searchable.

The documents can be viewed in the .md format or in a .html format.  Searching is provided in the .md display, and of course intrinsically in the web browser viewing .html.

TimoVJL provided the code/method to search the win32 documentation for API NAMES from which I created a database and the rest of the program.  See readme_v4.txt, for other external source code attributions.

It is possible that the MD_Files_3.db3 could be expanded in the future to include all topics in the win32-docs.zip and that would not require changing the basic program to be immediately useful.  TBD

It looks like I have got 3.0.2 working in Pelles C at least for unzipping to a file or memory.

I'll need to run some tests to see if it works for zipping too.

Making progress in either case.

Update - looking nice, it was able to zip a file and both 7z and WIN zip could access it and the file was extracted intact and readable.

Same example built with binary resource template :

include DlgBox.inc

DialogBox:

INCBIN "MyDlg.bin"

.code

start:

    mov     eax,RichEditANSIWndProc
    invoke  GetModuleHandle,0

    xor     ecx,ecx
    invoke  DialogBoxIndirectParam,eax,\
            ADDR DialogBox,ecx,ADDR DlgProc,ecx

DlgProc PROC hWnd:DWORD,uMsg:DWORD,wParam:DWORD,lParam:DWORD

    .IF uMsg==WM_CLOSE

        invoke  EndDialog,hWnd,0

    .ELSE

        xor     eax,eax

Thank Timo!  I'll give this one a try - maybe simple enough for me to use.

Update:  An older version of this (1.19) is what I am using now.  Back in about 2020 I went through the 1.19 code and succeeded in getting it to work for Pelles C.  Now looking at this version 3.0.2 it is just as difficult under Pelles C as 1.19 was but structurally it has changed a lot so a file difference does not highlight changes compared to what I did in 1.19 SO it is basically going to be starting all over......

Many times is good to keep line numbers intact.

Have miniz still problems with Pelles C 13 ?

Yes about what I did but a bit differently-
I added

Code Select Expand

    #ifdef _PELLESC__
        #define MD_ASSERT(cond)     do {} while(0)
        #define MD_UNREACHABLE()    do {} while(0)
    #elif at the beginning of the block there.

Flags are set to accommodate the GitHub idiosyncrasies, but
will probably work ok for any .md file.  Use the 'Convert other .md File'
button.

Here is a quick update of the program
Fixed needing the TOP button so that is now removed.

Added ability to list every name in the DB by entering an *
Hoping this makes it easier to find something -

Still need to modernize the ZIP code before posting sources.
