Desktop Goldfish

[WideBoyDixon]

I'm starting to get the hang of this GDI+ I think although I'm still learning. Here's another application that I've ported from a C# example. It's a goldfish that swims across your desktop from left to right and then from right to left. If you click on the fish then it swims a bit faster to get away. Something for a bit of fun only really.

Source code and required resources can be downloaded HERE.

There's some issues with trying to pick up and move the fish which I haven't yet investigated further. There's also an issue with the tray menu which doesn't seem to work at all. However, you can get rid of the fish by right-clicking it with the mouse.

If anyone can fix up the script or suggest better ways of doing this then I'm interested to hear them.

Have fun.

UPDATE: 29-May-2009

You can now add in extra fish from the tray menu. The initial number of fish can be changed at the top of the script. I still haven't solved the issue with moving the window with the mouse.

UPDATE: 1-June-2009

I've added a couple of new fish. Not as nice as the original but I'm no artist. There's also an INI file where you can configure the application. I still (still!) haven't solved the issue with moving the window with the mouse. Also fixed a HUGE memory leak.

You should use these flags when moving the window then the context menu will work

BitOr($SWP_NOZORDER, $SWP_NOSIZE, $SWP_NOREDRAW, $SWP_NOACTIVATE)

and add this ro your window class, then double click works.

$CS_DBLCLKS = 8

[WideBoyDixon]

Of course! I've updated the window moving and also the class creation as you suggested. I've re-uploaded the modified script to the original location. Dragging the fish with the mouse still doesn't work very well but I might leave this for now.

Thanks for the pointers ProgAndy

Looks great WBD

Praise indeed from a GDI+ master

See the original post. You can add in as many fish as you like. I've had 25 on screen at the same time.

G'day WideBoyDixon

Gota ask. Does the "I'm gonna eat you little fishy" mean anything?

When I saw it I remembered an epesode from "Red Dwarf" when Cat tries to eat a robot fish and uses exactly that phrase. :-)

Great program :-)

You got the exact reference . Smoke me a kipper, I'll be back for breakfast.

Updated with a couple of extra fish. The application is now controlled by an INI file. I also fixed a HUGE memory leak which was caused by some incorrect documentation in the help file. _GDIPlus_BitmapCreateFromGraphics needs to be paired with _GDIPlus_ImageDispose and not _WinAPI_DeleteObject.

My desktop is turning now into an aquarium.

When I double click on a fish then the program is closing. Is it your intension?

PS: btw, I'm not a GDI+ master!!!

[ProgAndy]

It is Really great

There's some issues with trying to pick up and move the fish which I haven't yet investigated further.

just call _WinAPI_SetWindowPos(...) after the assignment $gaFish[$nIndex][11] = $newPos[1] .

[WideBoyDixon]

Actually, it was my intention (I copied that from the original program). However, it can be a little overzealous so it's probably worth changing the code from this:

Case $WM_RBUTTONDOWN, $WM_LBUTTONDBLCLK
                _ShutDown(); Done

to this:

Case $WM_RBUTTONDOWN
                _ShutDown(); Done

You could even remove those two lines entirely if you want to only exit from the system tray.

just call _WinAPI_SetWindowPos(...) after the assignment $gaFish[$nIndex][11] = $newPos[1] .

Of course! Sometimes that answer is just a little *too* obvious. Thanks ProgAndy.

I may add some more fish yet or even adapt to other things. There's a great site for animated GIFs which I can convert in to suitable PNGs : http://www.sevenoaksart.co.uk/

Looks very cool

I'm using Windows 7 RC1

But it's really eating up my proc. Im using one core completely.

Also, somehow the traymenu doesn't work. But that may be due to my Win 7...

[WideBoyDixon]

Lots of fish = lots of proc unfortunately. Each individual fish has its own timer rather than moving them all on the same timer. I guess I could change that.

The traymenu *will* work ... you just need to keep clicking on it until you manage to hit an idle loop.

I'll take a look at possibly getting all the fish to run on the same global timer.

The fish look great WBD. But there is a little bug because on my PC the fish get chopped up sometimes when they reverse direction, a sort of "fish and chops".

Yeah I guessed as much

Thanks for the info.

Looks great indeed
