Nathan,

Did you ever figure how to put an icon in the system tray, using
a MODELESS DIALOG, *without* the DIALOG flashing on the Desktop
or the Taskbar before it was hidden? That's something I have
yet to figure out. In a reply to one of my prior postings,
Mr. Semen Matusovski assured me that it is possible to put an
icon in the Taskbar Notification Area, and have it respond to
mouse clicks with popup menu's, without even needing a parent
dialog. I have not been able to figure out how to do this.
As far as I can determine, a CALLBACK FUNCTION is needed to
accept/respond to the windows messages that is sent to the
app. And, I don't believe you can have a Callback Function
without a parent dialog/window.

Anybody have any ideas on this matter? If you do, I shouldn't
need example code to be posted - it should be sufficient to
tell me the steps necessary.

Thanks in advance!

Some code anyway....Hopefully this will be self-explanatory, your hwnd is a child under desktop, hidden, then do the normal NIM_ADD stuff for the taskbar....

'Do your register class stuff here
'
Then
'

'--------------------------------------------------------------
'*Get the handle of an existing window and pass this on as the
' parent to this window so we can hide our process from showing
' up on the task bar
'--------------------------------------------------------------
'hdTopWnd& = GetDeskTopWindow()
 hNextWnd = GetTopWindow(0)
 hParent  = GetParent(hNextWnd)
'--------------------------------------------------------------
'hParent& = %NULL

hWnd = CreateWindowEx(0,szClassName, _
                      "", _
                      %WS_POPUP Or %WS_DLGFRAME,_
                      %CW_USEDEFAULT, _
                      %CW_USEDEFAULT, _
                      %CW_USEDEFAULT, _
                      %CW_USEDEFAULT, _
                      hParent, _ '<-- assign to a parent window
                      %NULL, _
                      hInstance, _
                      ByVal %NULL)

'ShowWindow hWnd, iCmdShow
UpdateWindow hWnd

'Remove from Task list
pid = GetCurrentProcessId()
RegisterServiceProcess pid, 1  

'
'
'
'
Don't forget to destroy it:
       Case %WM_DESTROY
            PostQuitMessage 0

By the way, this is from SPYDER, an invisible program designed to gether information from a PC (Not spyware, but SPYWARE for security reasons not advertising).


There is no window created or visible, it's not "Modeless" so to speak but it works...
You should then be able to use the tray sample from the samples folder and go from there....

Thanks, Scott!

I've never messed with registering windows classes, but I'm
pretty adroit at figuring out MOST stuff from the Win32.Hlp
and MSDN. All of my programs so far have been of the basic
(pun not intended) utilities type that never required advanced
windows/dialog programming.

OK, now I've got some learning to do!

Thanks, again!

Clay,

I've come straight from Visual Basic, so i'm new to handling my own
window messages.. I can't get my window to not flash in the taskbar yet,
i'll have a look at the code Scott kindly posted.

Nathan, toolwindows do not show in the taskbar, so create the window using the extended style %WS_EX_TOOLWINDOW... make your DIALOG NEW statement like this (untested, off the top of my head):

DIALOG NEW hWndParent, "Toolwindow title", x, y, xx, yy, _  
  %WS_SYSMENU OR %WS_THICKFRAME OR %DS_MODALFRAME, _  
  %WS_EX_TOOLWINDOW TO hDlg

Nathan,

This message is for your information. I have found out, through
empirical testing, that if you use ShellExecute in a program
to run other programs asynchronously, it's not sufficient to
just use the DIALOG statement that Lance provided in order to
prevent the apps from flashing on the Taskbar. You've also got
to use the %SW_HIDE flag as the last parameter in the statement
that calls ShellExecute. Apparently, the last parameter in
that function (which is the window show state flag) overrides
the dialog new statement settings in the program that is
shelled to. My dialogs weren't actually displaying on the
screen, but they were flashing briefly in the Taskbar. Once
I changed the show window flag in the ShellExecute statement
from %SW_SHOWNORMAL to %SW_HIDE, the flashings in the
Taskbar disappeared. So, from the source that Lance nicely
provided, and from what I just learned, my dialogs don't
flash ANYWHERE on the screen.

You'll probably find this message useless, as I don't know
how common it is for other Members here to use ShellExecute,
but if you do, then I hope this helped!

Thanks, Lance!

P.S. My dialogs are all MODELESS. The WINMAIN functions use
DOEVENTS loops.
