Remove Gui

[p0wder]

I am trying to remove the window [not just make it invisible, but remove the code] from the example which i am using. I just want to execute the program, then have it immediately minimize and sit in the tray. any pointers on where to start?

INVOKE CreateWindowEx creates a window (or control.)

Nowhere is it stated that a Win32 application MUST create a window... however, if the application is going to sit in the system tray it should probably have a WndProc so that the WM_CLOSE message can be intercepted.

What have you tried so far?

[p0wder]

This is what I have so far, but it just runs in the background, how do i get it into the tray, ... also, what else can i remove?

Take a look at \masm32\icztutes\tute23, that almost does what you want. When the main window is minimized, the only thing visible is the tray icon. Now just make the window default minimized... :wink

[hutch--]

There is an old trick that used to work fine, If you need a WndProc type function, you need a window to point messages at it but you can easily create a window that is not visible on the screen by using negative co-ordinates for the top XY. It will still show on your Alt+Tab list but it does not get displayed. If you can imagine it, starting with the XY co-ordinates at -1000 it places the window about 1 metre above and to the left of your monitor.

[Mark Jones]

Hutch, is that a valid programming method? :lol

I recall some apps in earlier versions of windows which would get moved off the screen this way, sometimes this cause serious problems. Eventually I found a freeware app called "discover window" which would find these and bring them back on-screen.

Here's another hint about Icz tute 23: swap "WS_SOMETHING" with "WS_MINIMIZE" and the app will default to starting in the systray. :U

[hutch--]

Mark,

The method was always very reliable. You could solve the problem of a finder app, just detect the top XY and move it back again and if the finder persisted, keep changing the window title so it has to enumerate all the windows each time. A systray icon is an OK method but you can get tired of too many items on the systray.

Hutch,

A systray icon is an OK method but you can get tired of too many items on the systray.

That is certainly the way that I feel, I've got miine down to 9 items, 6 are hidden.  Which brings up another point.  Why work so hard to create an app that runs in the System Tray when, chances are, it will just be hidden.  What is the point?
