Description

Plug-in terminates application in 2 steps - first send WM_CLOSE to its main window, then (if still alive) terminates application. Has sync/async (background) modes, async is good for slowly exiting applications and multiple applications (multithreading). Plug-in closes or terminates all process with top level windows of such kind using EnumWindows(). Never closes installer $HWNDPARENT. Size is 2 kB in zip, so if you need WIN API calls for correct process termination only, this may replace System plug-in with less size and simple script code. Final package size is 4 kB less in compressed file for installer only and 8 kB if it replaces System plug-in both in installer and uninstaller.

Syntax

"fct" DLL function

fct::fct [/NOUNLOAD] [/WC CLASS | /WCP CLASS_PART]  [/WT WINDOW_TITLE | /WTP TITLE_PART] \
 [/ASYNC] [/MSGONLY] [/SCCLOSE] [/TIMEOUT xxx] [/UDATA xxx] [/QUESTION TERM_QUEST] [/END]

Searchs for all windows with predefined 'class' and 'title' (or it's part if /WCP or /WTP keys used). In async mode plug-in returns running terminator thread handle, in the sync one - still alive applications count (i.e. how many application not exited after WM_CLOSE and were not terminated using TerminateProcess() ). Returnes "-1" if /QUESTION was defined, application not exited after WM_CLOSE and user selected Cancel on the MessageBox. I.e. 0 is OK. Use 'wait' with handle as parameter to get final result for async mode.

WT

WINDOW_TITLE is a full window title

WTP

TITLE_PART is only a part of window title (caption)

WC

WINDOW_CLASS is a full window class name

WCP

CLASS_PART is only a part of window class name

ASYNC

Not waits for process exit. Use 'wait' call if you want to get result

MSGONLY

Not attempts to terminate process

SCCLOSE

uses WM_SYSCOMMAND SC_CLOSE instead of WM_CLOSE (for Window Explorer mainly)

TIMEOUT

timeout for SendMessage() and WaitForSingleObject(). Default is 1000 (ms).

UDATA

if few applications have "32770" class based windows and all titles include only a fragment of TITLEPART, situation becomes confusing. This case developer can preset specific GWL_USERDATA value to his app's window, plug-in will check, for example, /udata=0x12fe3400.

QUESTION

TERM_QUEST - text to display on the MessageBox if application not exited on WM_CLOSE. Skipped in the Silent mode.

END

Allows to limit plug-in stack reading (optional, required if you stores other vars in the stack).

"wait" DLL function

fct::wait handle

Waits for terminator thread exit in async mode.

handle

Control thread handle returned by 'fct' call in the /ASYNC mode.

Example

Sync execution:

    fct::fct /WC '${WND_CLASS}' /WTP '${MY_TITLE}' /TIMEOUT 2000 /QUESTION 'Terminate?'
    Pop $0
    StrCmp $0 "-1" 0 +2
    Abort "Terminated by user" 
    MessageBox MB_OK "Still Alive Count=$0"

Async execution:

    fct::fct /NOUNLOAD /WC '${WND_CLASS}' /ASYNC
    ;You can place some code here. We skipped Pop and Push for hThread - 
    ;it just sits in the stack. 'Question' not defined - silent execution.
    fct::wait
    Pop $0
    MessageBox MB_OK "Still Alive Count=$0"
