windows - Does GPL code linking with proprietary library depend which is created first? -

-

Microsoft makes its Windows and MFCC DLL libraries etc. An open source development writes a new MFC application and releases the source code GPL The app has to link to MS DLL / Library for running the app in Windows, but I do not think anybody can argue that now we have the right to give Microsoft GPL the power to DLL.

This means that the GPL license really depends on who "created" first? If the proprietary library is created first (such as Windows DLL) which is published without any links and GPL code and later a GPL program is connected, then the GPL program does not convert the proprietary library to GPL Although the ownership code is connected to the "GPL code".

If this happens, then such company of Nvidia or Real Networks can do the following? Let's assume that they want to keep proprietary HDDoding media decoding engine libraries private, but they also want the "leverage" open source GPLD code to display their hardware.

  1. They create a proprietary library to decode the media and release some sample code.
  2. Anyone (opensource development) creates a "plugin" that can have a GPLed code such as XBMC, MPlayer or VLC
  3. in this owned library because they can debate because they are the first proprietary library Created (as MS first makes all DLLs), GPL programs that are related to their ownership code are not written in the GPL code secretly. In theory, someone can argue that OpenSource Developer creates a GPL vlc.exe file that links to the Nvidia-owned Media Decoder Library, violating the GPL license.

    Does this mean that all GPL programs are running in Windows such as VLC, GIT, Sigwin etc are violating all GPL licenses because they need to be affiliated with the proprietary Microsoft Windows Library. Episode 2: What's wrong with this:

    Nvidia can create a new hardware residue library that hides the latest graphics functions. They also make a freeBSD driver along with this library and release the source code of the BSD driver but not the library source code.

    Someone (Linux Developer) can implement Linux Driver which links to this library, Nvidia Graphics driver for Linux but since Nvidia did not do it, they enabled "Linux support" enabled. The library can keep the source "hidden" while doing so.

    This definitely violates GPL's spirit.

    Does this mean that running any XI created with GPLaid source in Windows / Mac / iPhone / PSP3 also violates GPL's sense?

MVP, design question -

-
I am working on an MVP designated application and there are some design questions: I presenter how to communicate while writing code in the layer Should go between different presenters / ideas? Let's say I have a window window with a window viewer and I want to set the window title on the window from the second window. I have a title-setter on the window view, which wraps the actual Gui title. Should I call the title-setter directly on the scene (window viewer.tit = "title") or should I wrap the view title as the presentation title setter (window-creator.tit = "title")? Ask yourself how you will test it? If you do a window presentation. View. Tight = "Title", how can you test that the presenter is setting the title?

excel - Populate list via a bi-Condition -

-
I'm interested in implementing something but I'm not sure it would be possible and would like to take it on. This is my scenario: I will have two verification cells, which will be shown as a list, from which I will select. This is my condition that I want to remember and remember my list from a database. I have a list of agents, which has been thrown at B13: B23 and the next two, I have columns of data that assume that my data base looks like this bcdx | Y Z Agent 1 1 | 1 | 0 Agent 2 0 | 1 | 0 Agent 3 0 | 1 | 1 agent 4 1 | 0 | 0 ... I want to populate a list named agent from column B, when I verify cell 1: x and verification cell 2: 1 I choose from. It should only show an agent in column X with column: agent1 agent4 or 0 ... I read somewhere Array formula but I do not know if this is convenient and I have unfortunately not any background in the macro :( But I know C ++ is quite easy with some conditional statement like this. Advance Thanks, This

iphone - How do I make a UIPickerView in a UIActionSheet -

-
Just want to know how I will create UIPickerView in a UIActionSheet with a simple array. Well, I really know how to put it in an action sheet but I like my way because it is more for my app, thanks, but I I also want to know how to put options in UIPKviewView, I just have an array with colors already on top of that part: red, green, blue, yellow, black, etc. in this, but I want to know how it In the preview d L'be if I am using the already Instifrem:? Please help anyone. I know that this is a stupid question, but I'm cheating my head on my $$$$$$ MacBook. Instead you want to do this, create your UIPickerView interface builder and have it in your view controller Connect to the outlet. Add it as a subview of your main view and set its frame coordinates so that it is offset right below the edge, x = 0, y = 480 Then, when you want to display a picker, animate it like something with the screen: [UIView startup permissions: zero reference: zero]; [Color picture setfr
