262144 (Win32 MB_TOPMOST) has no mapping in the .NET MessageBoxOptions enum, whose
only members are RightAlign/RtlReading/ServiceNotification etc., so PowerShell
rejected it: "cannot convert 262144 to MessageBoxOptions" (second failure of the
topmost attempt). Correct documented way is passing a TopMost invisible owner
form as the first argument of MessageBox.Show. Wrapped in try/catch that falls
back to a plain Show, so the dialog can no longer fail the node even if the
owner pattern misbehaves on some machine.
Previous topmost attempt passed 'HelpButton' in the MessageBoxOptions position of
MessageBox::Show, so PowerShell failed at runtime with "cannot convert value
HelpButton to type System.Windows.Forms.MessageBoxOptions" (reproduced in flow run:
notice node failed at char 196). Now passes the documented MB_TOPMOST flag
(MessageBoxOptions)262144 as the 6th argument, keeping the six-argument overload
(OK / Information / Button1 / topmost).
adm-zip throws "ADM-ZIP: Invalid filename" both for corrupt entries AND when the
archive file simply does not exist, which sent us chasing phantom filename issues.
Now the handler checks file existence first and reports "压缩包不存在:<path>" with a
recommendation pointing out that File_CompressFile appends .zip to the full source
name (a.txt -> a.txt.zip) and that the compress node's output variable should be
used to chain the real artifact path.
Catalog contract: search is a select ("0"=content / "1"=digits / "2"=phone / "3"=email
/ "4"=ID card / "5"=custom regex) with the target in Config. Old implementation used
first(args, ["search","Config"]) so the enum value "0" was split on as literal text,
making content-replace never work (same family as W26-W33 enum mapping bugs).
Now implements all six modes with preset patterns, regex mode guarded by try/catch,
and falls back to legacy literal behavior when Config is empty.
Root cause of second failure (120s timeout): VB InputBox has no topmost
flag and no taskbar presence, so it renders BEHIND the main window.
User never sees it, flow waits until node timeout (120000ms).
Fix:
- Dialog_InputBox now builds a WinForms form with TopMost=true,
ShowInTaskbar=true, CenterScreen, OK/Cancel buttons
- MessageBox notice adds MB_TOPMOST via options param
- Flow updated: 3 sequential InputBox nodes replaced by ONE
Dialog_GetConfigV7 form (topmost BrowserWindow via host bridge),
3 fields filled in a single window, wait_time=10min
- Flow node timeout raised to 660s to exceed the 600s PS-level wait
- Fixed latent bug: Time_WeekDay node had empty outputVar, so
the "星期几" variable never existed
Root cause: Dialog_InputBox and other blocking dialogs wait for user
input, but powershell() default timeout 30000ms kills the still-waiting
dialog process, reporting generic "Command failed" (reproduced: run
failed at 30.08s).
Fix:
- InputBox/Notice default wait 600s, adjustable via wait_time arg
- File dialogs (OpenFile/OpenFiles/SaveFile) wait up to 30min
- InputBox timeout reports dialog_timeout with clear guidance instead
of misleading command failure
