I would like to write a small utility that moves a window from one space to another in OS X Lion. I don't care if the utility is written in AppleScript or Objective-C. What I can't seem to figure out is given a window, how can I move it to a different space. I've seen lots of helpful information in this thread, but nothing about how to actually move the window. If anybody has any thoughts or ideas, I'd appreciate hearing them. Thanks.
If you are using objective-c calls, then moving between spaces in 10.7 is actually the same as 10.6 except for one issue. Space ID's were index based in 10.6, but based on something else (not quite a GUID) in 10.7.
If you have a window already in the correct space, the solutions in this question will work (I'm using it in csshX). You can get the space ID with CGSGetWindowWorkspace, and then set it on another window using CGSMoveWorkspaceWindowList.
Now if you don't have the space id - e.g. you just want to move the window to the 2nd space - then I'm as stumped as you are. I'm looking for the linkage between the space id and the index number. (Will update this answer if I find it)
Finally, you mention the App Store in the comment above - this will not be suitable since the CGS* calls use undocumented private frameworks which will get you rejected.
You will need to use a custom library, which can be found here http://macscripter.net/viewtopic.php?id=23453, however I'm not sure what kind of support it has in lion.

I would like to use MapKit (on osx) to display custom map tiles from a .mbtiles (sqlite) database of the sort exported from TileMill.
MBXMapKit looks great, and is almost what I'm looking for. I could see how, with very little modification, MBXMapKit could be tweaked to point to a local .mbtiles database file.
Is there any way to use the MBXMapKit framework to accomplish this without tweaking? I did read the docs, and couldn't find a straightforward answer. I did find a private method on MBXOfflineMapDatabase called -initWithContentsOfFile: which sounds promising and looks like it does what I need -- is there anything to watch out for if I expose and use that method?
Alternate option is to subclass MKTileOverlay and use -loadTileAtPath:result:, which is easy to do, but also requires managing the connection to the sqlite file etc.
Have a look at this for the latest on MBTiles support:
https://github.com/mapbox/mbxmapkit/issues/3
It'll be coming probably in the next release. This should be distinct and separate from both the normal performance cache (NSURLCache) as well as the (also SQLite-backed) offline databases, which are meant for individual tile downloads being placed into a cache one-by-one.
It took me quite some time to work this out, but here is the link that got me on the right path.
https://github.com/mapbox/mbxmapkit/pull/110/commits/8b9fbf3fd56ae804a38c737305f128fd43a8225d
For some reason the method _mbtilesOverlay = [[MBXMBTilesOverlay alloc] initWithMBTilesURL:mbtilesURL]; can not be used on the latest version of MBXMapKit. I just replaced the .m and .h files with the files in the link, and used MBXViewController.m as a guide to get the map view to show the tile overlay.
I'm becoming mad trying to figure out how to resolve this task. My goal is pretty easy, copy a file on the USB stick every time that it is inserted and then release the USB stick turning off the LED. What is the best way to solve it?
1) I found this article
http://geekswithblogs.net/BruceEitman/archive/2008/06/13/windows-ce-monitoring-for-disk-insertion-to-add-support-for.aspx
or
http://geekswithblogs.net/BruceEitman/archive/2008/06/13/windows-ce-monitoring-for-disk-insertion-to-add-support-for.aspx
but I can't translate it on VB.NET project.
2) Then I read that is enough to use RequestDeviceNotifications for block devices. But How can I do that in VB.NET?
I would like to avoid OpenNetCF if possible.
Thank you
Since you don't want to "use OpenNETCF" I assume that you don't want to use any libraries or capabilities not built in to the CF. We'll skip the argument of that silliness and the "value of your time" discussion and take that as a requirement.
What you need to do is:
Use P/Invoke to call CreateMsgQueue. That's going to give you back a Handle. You'll probably want to do CloseMsgQueue as well for completeness
P/Invoke RequestDeviceNotifications and pass it the handle returned from #1 above along with the DEVCLASS GUID value for the device notifications you want - probably STORE_MOUNT_GUID. Again, adding StopDeviceNotifications for completeness is a good idea.
At that point you'll get a message on the queue whenever a insert or remove happens. You then call ReadMsgQueue to get the DEVDETAIL data in the message.
Parse the DEVDETAIL and look at the fAttached member.
It'd take me a while to write that for you, so you'll need to do this on your own.
Start writing the project, find P/Invoke routines for the calls you need (like FindFirstFile and CreateProcess). On SO, have a look at Storage Card Problem In windows mobile and How to register form for WM_DEVICECHANGE message in windows mobile.
You are only going to be dead in the water if you can not find a particular call that you can't make.
As you work through your project, post (or search for) the actual problems you run into.
Otherwise, it sounds like you are asking someone to write the project and hand it to you.
I'm currently trying to write a program in VB.NET which fluidly changes the DWM window colorization colors in Windows 7.
I first tried to edit Registry values directly, but I had to restart the UXSMS service. This solution was unsatisfying, because of the toggle of the taskbar.
I'm now searching for a function in a DLL such as user32.dll or themecpl.dll which can reproduce the behaviour of control panel when setting the window color.
I'm now on IDA, searching for the adquate function (CColorCplPage::SetDwmColorizationColor seems good!). If anyone has one, please share it!
(If anyone need screens or code, please ask. Sorry for my poor English.)
Your first attempt failed because manually editing the Registry is never the correct way to change system settings. As you found out, lots of Windows components (and other applications!) read those configuration values once and cache them, preventing your changes from being propagated. Another problem (and you'd be surprised how often I see this) is applications that attempt to muck around in the Registry generally end up corrupting things.
Instead, you should call the documented API to change the settings. There's almost always a documented way of doing this, and if there isn't, well then you shouldn't be doing it.
This appears to be one of those cases. There's a documented DwmGetColorizationColor function, but there's no corresponding DwmSetColorizationColor function, as one might expect.
The reason is that the user is supposed to be the only one who can change their colorization settings, not other applications. You might promise not to abuse this, and to only make such changes at the user's explicit request, but not all applications can be trusted to do this. Lots of people would use it maliciously, so these functions have not been documented and exposed.
But as usual, if you press on, you can usually find an undocumented way of doing things. The problem with using undocumented functions is that there's no guarantee they'll work or continue to work. They've been intentionally left undocumented because they're liable to change on new versions of Windows. You should only use them at your own risk.
In this case, if you use a program like DumpBin to obtain a list of all the exported functions from the DWM DLL (dwmapi.dll), you'll see a number of undocumented exported functions.
The ones you're interested in are DwmGetColorizationParameters and DwmSetColorizationParameters. Both of these functions take a COLORIZATIONPARAMS structure as an argument that contains the values they need.
So, you need to reverse engineer these functions and obtain the appropriate definitions. Then, you can call the DwmGetColorizationParameters function, passing in a COLORIZATIONPARAMS structure to obtain the current configuration settings; modify the member of the structure that contains the current colorization color; and then pass that modified version of the structure to the DwmSetColorizationParameters function.
Did I mention that I don't recommend doing this?
I want to develop a VGA graphics driver (for Linux(Ubuntu)) with support for the basic primitives such as putpixel, drawline, fillrect and bitblt. I want to do it in protected mode.
I´ve been googling for a week and the following four links are the best I have found:
http://www.brackeen....vga/basics.html
http://www.osdever.n...VGA/vga/vga.htm
http://bos.asmhacker...sing%20bios.htm
Unfortunately, the first one uses a BIOS call so I cannot use it. The second link has lots of information on the VGA registers but no examples showing how to make them work together. The third example is a example to switch in 13h mode but i've tried it and nothing happened. Can you guys give me a hint? Thanks in advance!
--Vincenzo
my code at http://bos.asmhackers.net/docs/vga_without_bios/snippet_5/vga.php
works fine if you are in 32bit mode with full hardware access. Unfortunately I doubt that any Linux variant will let you directly access the VGA ports. I'm not sure how you develop this driver, but if you made sure that you have full access to the VGA ports it should work. In my example code I only switch between mode 0x03 and 0x13, but in the folders above you'll be able to find port values for most other common VGA modes, as well as C code to do the switch if you prefer that.
Christoffer code include files are found BOS operating system source code like text.inc and font8x16.inc

This is coming many many years later but I think it's still very relevant and if somebody is struggling I hope they can find it useful.
First of all, it is completely possible to configure VGA only using registers without interrupts, as hard as it may be. A useful resource about registers and how to configure them can be found here, but unless you have a ton of time to spare to learn how to properly do all of it, move to the following section.
If you wish to really learn how to do it, I suggest going through with the documentation provided earlier. However, some of it is already done!
Chris Giese did a great job demonstrating exactly how to do this for MS-DOS system, and while you may think that doesn't help you, it really does.
Chris's code can be found here. If you want another useful codes check here as well.
Now, while it only works for MS-DOS it's actually easy to convert to other systems. The code already contains all data needed to configure the registers in many different modes. And that's the part that saves you a ton of time going through documentation.
The code uses functions outportb, inportb, which are MS-DOS functions, to write/read single byte to/from a port. Therefore, you have to redefine these functions to read/write for your own system. Redefinition complexity depends on the system you operate on.
In addition, you will also need to provide means to write to physical memory region between 0xA0000-0xBFFFF which corresponds to standard VGA memory area. Once you have that allocated, you need to also redefine the functions pokeb pokew peekb which will help you output things (text or pixel data) on the screen.
One last note: the code is already defined to work with many different modes including both text and display modes.
The project I am currently working on requires a lot of hexadecimal numbers to be entered into the code.
I once saw a pic of an old keyboard with a hexadecimal numpad (has A-F letters on it also) replacing the normal numpad. Anyone know where I can get one of these?
IPv6 Buddy -keypad should work well for hexadecimal input.
http://www.ipv6buddy.com/
If you can get your hands on one of the retired space shuttles, they have one!
I have an old Heathkit learning toy with a hex numpad because the only way to program it was to assemble code by hand (it came with a 6800 manual and some notepads) into the online monitor. This was actually fun!
Mine is missing the 'D' button however.
Great idea with the programmable keypad. I think i am going to pick up one of these: DX1 input system. Works for any reconfiguring I might want to do.
Is this the one you're talking about?

While this has a lot of "gee whiz" appeal, I have to say:
You have two hands. Use them. A-F are all reachable with the left hand on a standard keyboard while your right hand is on the num-pad. Instead of putting muscle-memory time into some arcane Hex-pad, you'll be learning to touch-type with your left hand, which has application outside your current project.
Better yet, come up with a smarter way of getting the hex codes into your code. Write a script that extracts them from your data-source and into your code as symbolic variables... or whatever.
EDIT
Ok, I'll give you the benefit of the doubt. Lets assume you're working on a hardware project and need to provide a specialized interface for your user. Maybe a programmable keypad would fit the bill?
Not sure of the specifics right now, but I'm pretty sure you can easily write a keyboard remapper. You could remap the QWASDF keys to ABCDEF in order to type them more quickly. That way you could use 2 hands to type. Or if you are in control of the program they are being typed into, you could just translate the keys in code on the fly.
