What's New in FWH 26.07

Highlights of FiveWin for Harbour/xHarbour version 26.07 (July 2026). See also whatsnew.txt in the FWH root for the full day-by-day log.

New sample samples/DesktopWeb/login.prg: a single application that exposes the same HTML/CSS/JS to the desktop shell and to any web browser.

Multi-thread HTTP server on port 8080 (hb_threadStart + hb_socket*; build with -mt)
Desktop: TWebView2 navigates to http://localhost:8080/
Browser: open the same URL
Shared pages: modern login card and clinic appointments dashboard
Shared business logic: ValidateLogin() in Harbour; cookie session DWSESS
API: POST /api/login, POST /api/cmd, GET /dashboard, GET /logout
Demo credentials: admin/1234, demo/demo

Build: cd samples\DesktopWeb then build.bat (or build_new.bat login hm64 -mt). Requires WebView2 Runtime for the desktop window. See TWebView2.

Remote View + WebView2 (testrvweb)

New sample samples/RemoteView/testrvweb.prg combines Remote View with TWebView2:

Native FWH toolbar (demo HTML, Navigate, Eval, click counter)
Embedded Edge WebView2 with demo page and SendToFWH → bOnBind bridge
RemoteViewStart on port 8080 so the same window is live from any browser on the LAN

Layout tip for same-screen development: place the real desktop window low on the screen (FROM nTop, nLeft … PIXEL) so the browser image stays above it; use a modest RemoteViewSetOffset. Requires the WebView2 Runtime. Full notes: Remote View + WebView2.

XBrowse multi-line cell + LimitText (xbrml250 sample)

New sample samples/ui/xbrowse/xbrml250.prg shows how to edit a long character column in several lines inside the cell, while capping the length (example: 250 characters).

Use nDataLines >= 2 and leave cEditPicture empty so XBrowse creates a TMultiGet (word-wrap while typing). Setting cEditPicture := Replicate( "X", 250 ) forces a single-line TGet and disables wrap.
bOnPreEdit: always RTrim() the editor text, then oEditGet:LimitText( nMax ). Fixed-length padded values (PadR / Space(250)) already fill the limit and block typing; TMultiGet does not auto-SelectAll like TGet.
Keys: ENTER ends the cell edit; Ctrl+ENTER or Shift+ENTER inserts one real line break. Do not call Replace( CRLF ) yourself or you get two breaks (your insert plus the multiline EDIT / ES_WANTRETURN).
bOnPostEdit: store Left( xVal, nMax ) (optionally PadR if the backend needs a fixed width).

Full notes: TXBrowse multi-line cell edit.

TControl F1 / CHM help — empty nHelpId bubbles to parent

F1 / WM_HELP is delivered to the focused control. When the control had an empty nHelpId, FWH returned without opening help, so oWnd:nHelpId / oDlg:nHelpId was never used. TControl:__HelpTopic() now calls ::oWnd:HelpTopic() so the window/dialog context is applied.

CHM context help behaviour:

Control numeric nHelpId — HelpPopup() (small popup; requires SetHelpPopup( "popups.txt" ) for CHM text popups)
Control character topic name — HelpTopic() full CHM viewer
Window/dialog nHelpId or empty control id — parent HelpTopic() full CHM viewer
Explicit HelpTopic( nId ) / HelpTopic( "topic" ) — always full CHM viewer

Topic names must match real .htm files inside the CHM. HelpSetPos() only applies to classic .hlp, not CHM. Sample: samples/test/testchmhlp.prg (+ popups.txt). Rebuild the PRG library after update.

samples/misc/dshow.prg — webcam (Media Foundation)

samples/misc/dshow.prg shows live webcam preview and BMP snapshot in a FiveWin dialog. On Windows 10/11, DirectShow IVideoWindow / GetCurrentImage often produces a black buffer even when the filter graph is running (verified with FaceTime HD / UVC). The sample therefore uses Media Foundation through C code embedded directly in the PRG.

Self-contained C: the former mfcam.cpp helper was converted to C inside #pragma BEGINDUMP. GUIDs and minimal COM vtables are declared locally; MF/COM entry points are resolved at runtime from system ole32, mfplat, mf and mfreadwrite DLLs. No mfcam.dll, MF SDK headers or mf*.lib import libraries are required.
UI: a timer grabs each frame to a BMP and loads it into a real IMAGE control (live preview) and optional snapshot.
Toolchains: any sample variant via build_new.bat; verified with xHarbour + BCC32 (xb32).
Diagnostics (optional): build_camtest.bat builds pure C++ tests without FiveWin — camtest_mf64.exe (MF, recommended) and camtest64.exe (DirectShow; often black on the same hardware).

cd samples\misc
build_new.bat dshow xb32
dshow.exe

FW_DemoDB() — new demo MySQL host

The free cloud demo MySQL server used by FWH samples has moved. FW_DemoDB() now connects to a single host:

Host: mail.fivetechsoft.com
Database: fivetech_test
User: fivetech_test
Password: fivewin2026

The former second server (nServer = 2) was removed. If the first parameter is a character string it is still treated as cLib ("FWH", "ADO" or "DLP"); numeric values are ignored. Existing sample calls need no source changes after rebuilding the PRG library.

oCn := FW_DemoDB()           // FWH native (default)
oCn := FW_DemoDB( "ADO" )    // via ADO
oCn := FW_DemoDB( "DLP" )    // via Dolphin, if linked

See also MariaDB / MySQL — FW_DemoDB().

TWebView2 — Fixed Version Runtime

TWebView2():New() accepts a third optional parameter cBrowserExecutableFolder (Microsoft's browserExecutableFolder). When set, WebView2 loads a Fixed Version / standalone Runtime from that folder instead of the Evergreen Runtime installed on the system.

Useful on older OS (e.g. Windows Server 2012 R2) where current Evergreen builds no longer work
Useful when the Runtime cannot be installed machine-wide
Path = Fixed Version root (folder that contains msedgewebview2.exe)
Must be passed in the constructor (the environment is created in New())
Existing code without the parameter is unchanged

oWeb := TWebView2():New( oWnd, , "C:\MyApp\WebView2Runtime" )

Also fixed: the second parameter cUserDataFolder was being overwritten with a default AppData path; it is now honoured.

Full reference: TWebView2.

Other July 2026 fixes

MAPISendMail — when TO is given with a single parameter, fill empty lpszAddress from the display name (Thunderbird / stricter Simple MAPI clients)
TXBrowse:SelectRow() — zero-divisor when using multi-select columns without totals
window.prg — added TSBROWSE to cBrwClassList
dshow.prg — webcam sample via self-contained Media Foundation C code; see above
TControl F1 help — empty nHelpId bubbles to parent (see above)
