Fast add an icon to the tray?..

[Alexander Doc]

Hello!
How immediately with program start add an icon to the tray (with popupmenu)? without show the dialog?
The DDT engine sets the WS_VISIBLE style for each dialog, if you want or not. (...in example Tray.bas)
Please, help me.

Thanks

Alexander

If I understand what you are trying todo is to add the ICON to the tray but not display the Dialog?

You can't do this with the DDT, you have to build your Dialog with the Dialog Editor and not set the Dialog Flag (WS_VISIBLE) to Display, then Compile it with the Resource Editor. Thats how I had to do it... For me it was a learning curve to learn the in's and outs of building a Dialog this way but it was time well spent.. )

Hope this helps point you in the right direction.

If all you want to do is keep a DDT-created dialog from showing, you should be able to specify a screen location that is not visible to the user, like 10000,10000.

If you also want to hide the Task Bar button, that is a little more complicated. It was discussed in a recent thread, and it can be done, but I can't seem to find the thread. If I have time later I'll look some more, but maybe somebody will remember it and will post the thread's forum and name...

That's why I couldn't find the thread I was looking for, we talked via email.

The solution is this...

If you use the %WS_MINIMIZED style in your DIALOG NEW statement, the dialog will appear minimized when you execute DIALOG SHOW. And if you also use the %WS_EX_TOOLWINDOW extended style, which creates a dialog without a Task Bar button, then nothing at all will appear on the screen when you use DIALOG SHOW.

The only problem is that if you click the Sys Tray icon and show the dialog, a Task Bar button will not appear. But you could get around that too, by using the original toolwindow dialog as a "dummy" window for the receipt of Sys Tray icon clicks, and when they are received, use DIALOG NEW to create an all-new dialog that does have a Task Bar button.

I have better Idea of Lance Edmonds:
... in response to a %WM_INITDIALOG message in your dialog callback, use PostMessage() to send the dialog a %WM_USER message. In response to the %WM_USER message, perform a DIALOG SHOW STATE statement.

{...
Case %WM_INITDIALOG
.....
dumm& = PostMessage(hDlg, %WM_USER, 0, 0)

Case %WM_USER
DIALOG SHOW STATE hDlg, %SW_HIDE
{...

Regards,
Alexander

Alexander,
Not sure about the WM_USER, but I did try the SHOW STATE under the WM_INITDIALOG and that did not work... The best way is to not do it in DDT... That way you have full control over the Dialog.

You can't use DIALOG SHOW STATE in %WM_INITDIALOG as the DDT engine has not finished setting up the dialog at that point. That is the reason for the PostMessage() call, so that the "hide" code gets executed after the remaining setup is completed.

One footnote: some controls send notification messages that conflict with %WM_USER, so it may be better to use (%WM_USER + 700) or use RegisterWindowMessage() to create a private message that is guaranteed not to conflict. This requires at least one STATIC variable to hold the message value between iterations of the callback.

I use %WM_USER + 400 ... is it OK?
and DIALOG SHOW STATE by ...CASE %WM_USER in function
DialogProc make no error. Is it mistake???:
...
%WM_TRAYICON = %WM_USER + 400
...
FUNCTION DialogProc(BYVAL hDlg AS LONG, BYVAL wMsg AS LONG, _
BYVAL wParam AS LONG, BYVAL lParam AS LONG) AS LONG
STATIC hMenu AS LONG
STATIC ti AS NOTIFYICONDATA
STATIC p AS POINTAPI

SELECT CASE wMsg

CASE %WM_INITDIALOG
' Get Menu Handle
dumm&=PostMessage(hDlg, %WM_USER, 0, 0)
hMenu = GetSubMenu(LoadMenu(sdDialog, "POPUPMENU"), 0)

' Add tray icon
ti.cbSize = SIZEOF(ti)
ti.hWnd = hDlg
ti.uID = sdDialog
ti.uFlags = %NIF_ICON OR %NIF_MESSAGE OR %NIF_TIP
ti.uCallbackMessage = %WM_TRAYICON
ti.hIcon = LoadIcon(sdDialog, "...")
ti.szTip = "..."
Shell_NotifyIcon %NIM_ADD, ti
DestroyIcon ti.hIcon
FUNCTION = 1

CASE %WM_USER
DIALOG SHOW STATE hDlg, %SW_HIDE

CASE %WM_TRAYICON

SELECT CASE LOWRD(lParam)

' Right button press
CASE %WM_RBUTTONDOWN
IF IsWindowVisible(hDlg) = %FALSE THEN
SetForegroundWindow hDlg
GetCursorPos p
TrackPopupMenu hMenu, 0, p.x, p.y, 0, hDlg, _
BYVAL %NULL
Postmessage hDlg, %WM_NULL, 0, 0
END IF

END SELECT
....

Don't quote me on this (I may be wrong), but the highest message used by the common and standard controls seems to be below %WM_USER + 300.

In your code above, the %WM_TRAYICON = (%WM_USER + 400) should be fine, but you should also change the PostMessage() and CASE %WM_USER to use a higer value, ie, (%WM_USER + 401).

As discussed in above, adding %WS_MINIMIZE to the dialog style for the initial dialog may be useful to stop the "flash" of the dialog as the app starts. Either that, or make the dialog look like a splash screen as it starts.
