  • Is displayMetrix xdpi and ydpi accurate?

    - by oddvark
    Can the xdpi and ydpi settings be relied upon to accurately represent the physical pixels in once inch of screen space? I need this to be accurate for some display code I'm writing. I realize the documention says that this is the case, but I need to know if individual handsets get this right MOST OF THE TIME. I know I can alternately use "densitiy" which will give me 120, 160, 240 steps of DPI, but an exact dpi would be much better. Thanks!

  • Is PHP still basically Procedural Overall?

    - by coffeeaddict
    I know PHP 5 has some object oriented similarities but it's not a true OOP environment still right? Also does it have a true compiler? I see compiling of scripts which still means procedural. I assume it's not a real compiler in that any PHP compilers out there do not create assemblies?

  • Help with data retrieval MACRO

    - by Andrei Ciobanu
    Hello, given the following structure: struct nmslist_elem_s { nmptr data; struct nmslist_elem_s *next; }; typedef struct nmslist_elem_s nmslist_elem; Where: typedef void* nmptr; Is it possible to write a MACRO that retrieves the data from the element and cast it to the right type: MACRO(type, element) that expands to *((type*)element->data). For example for int, i would need something like this: *((int*)(element->data)) .

  • Where are SSIS Packages Saved?

    - by Chris
    I right clicked on a Database in the object explorer of SQL Server 2008 Management Studio. I went to Tasks Import Data, and imported some data from a flat text file, opting to save the package on the server. Now how the heck do I get to the package to edit or run it again? Where in SQL Server Management Studio do I go? I've expanded everything and I can't find it. It's driving me nuts.

  • syntax for binding multiple variables within text

    - by danke
    When binding multiple variables value1 value2 value3 in the same text field, do I do this: text="{some text value1 other text value2 and other text value3}" or text="some text {value1} other text {value2} and other text {value3}" I noticed both work, but which is the right way to do it and will work all the time.

  • LoaderContext and ApplicationDomain changes with Adobe AIR ?

    - by Tyn
    Hello, I'm currently experimenting with loading external SWF files from both an standard AS3 application, and an AIR application. It seems that the AIR application doesn't act the same way a standard SWF run by the Flash Player does. According to the documentation, the applicationDomain property of LoaderContext is usable in an AIR application too, but it just seems to be not working. I have the following code : package { import flash.display.Loader; import flash.display.LoaderInfo; import flash.display.Sprite; import flash.events.Event; import flash.net.URLRequest; import flash.system.ApplicationDomain; import flash.system.LoaderContext; public class Invoker extends Sprite { private var _ldr : Loader; public function Invoker() { _ldr = new Loader(); _ldr.contentLoaderInfo.addEventListener(Event.COMPLETE, onChildOneComplete); var ldrC : LoaderContext = new LoaderContext(false, new ApplicationDomain(ApplicationDomain.currentDomain) ); _ldr.load(new URLRequest("otherSwf.swf"), ldrC); } private function onChildOneComplete(e : Event) : void { var c1ad : ApplicationDomain = (e.target as LoaderInfo).applicationDomain; var inad : ApplicationDomain = ApplicationDomain.currentDomain; trace("Child One parentDomain : " + c1ad.parentDomain); trace("Invoker parentDomain : " + inad.parentDomain); trace("Child One has Invoker : " + c1ad.hasDefinition("Invoker")); trace("Invoker has Invoker : " + inad.hasDefinition("Invoker")); } } } Compiling this code as an SWF file and launching it with the Flash Player does this output, which seems right : Child One parentDomain : [object ApplicationDomain] Invoker parentDomain : null Child One has Invoker : true Invoker has Invoker : true But the same code as an AIR application does a different output : Child One parentDomain : null Invoker parentDomain : null Child One has Invoker : false Invoker has Invoker : true According to the documentation, the first output (using a SWF with Flash Player, and not an AIR application) is the right one. Also, playing around with this snippet and changing the application domain to others possible configurations (like new ApplicationDomain(null), or ApplicationDomain.currentDomain) does exaclty what the documentation says with the SWF, but does not change the output of the AIR application. Any clue why AIR is simply ignoring the application domain passed to the loader context ? Any documentation about this particular issue ? Thank you very much.

  • Ideas on implementing threads and cross process communication. - C

    - by Jamie Keeling
    Hello all! I have an application consisting of two windows, one communicates to the other and sends it a struct constaining two integers (In this case two rolls of a dice). I will be using events for the following circumstances: Process a sends data to process b, process b displays data Process a closes, in turn closing process b Process b closes a, in turn closing process a I have noticed that if the second process is constantly waiting for the first process to send data then the program will be just sat waiting, which is where the idea of implementing threads on each process occured. I have already implemented a thread on the first process which currently creates the data to send to the second process and makes it available to the second process. The problem i'm having is that I don't exactly have a lot of experience with threads and events so I'm not sure of the best way to actually implement what I want to do. Following is a small snippet of what I have so far in the producer application; Rolling the dice and sending the data: case IDM_FILE_ROLLDICE: { hDiceRoll = CreateThread( NULL, // lpThreadAttributes (default) 0, // dwStackSize (default) ThreadFunc(hMainWindow), // lpStartAddress NULL, // lpParameter 0, // dwCreationFlags &hDiceID // lpThreadId (returned by function) ); } break; The data being sent to the other process: DWORD WINAPI ThreadFunc(LPVOID passedHandle) { HANDLE hMainHandle = *((HANDLE*)passedHandle); WCHAR buffer[256]; LPCTSTR pBuf; LPVOID lpMsgBuf; LPVOID lpDisplayBuf; struct diceData storage; HANDLE hMapFile; DWORD dw; //Roll dice and store results in variable storage = RollDice(); hMapFile = CreateFileMapping( (HANDLE)0xFFFFFFFF, // use paging file NULL, // default security PAGE_READWRITE, // read/write access 0, // maximum object size (high-order DWORD) BUF_SIZE, // maximum object size (low-order DWORD) szName); // name of mapping object if (hMapFile == NULL) { dw = GetLastError(); MessageBox(hMainHandle,L"Could not create file mapping object",L"Error",MB_OK); return 1; } pBuf = (LPTSTR) MapViewOfFile(hMapFile, // handle to map object FILE_MAP_ALL_ACCESS, // read/write permission 0, 0, BUF_SIZE); if (pBuf == NULL) { MessageBox(hMainHandle,L"Could not map view of file",L"Error",MB_OK); CloseHandle(hMapFile); return 1; } CopyMemory((PVOID)pBuf, &storage, (_tcslen(szMsg) * sizeof(TCHAR))); //_getch(); MessageBox(hMainHandle,L"Completed!",L"Success",MB_OK); UnmapViewOfFile(pBuf); return 0; } I'd like to think I am at least on the right lines, although for some reason when the application finishes creating the thread it hits the return DefWindowProc(hMainWindow, message, wParam, lParam); it crashes saying there's no more source code for the current location. I know there are certain ways to implement things but as I've mentioned I'm not sure if i'm doing this the right way, has anybody else tried to do the same thing? Thanks!

  • What is a good PDF report generator tool for python?

    - by jlouis
    What is a good tool for PDF report generation in Python? I've checked out ReportLab, but it seems to be awfully low-level for what I want to do. My current hunch is to call TeX on the command-line and let it produce the PDF, but if there is something that is easier to work with (and looks professional - We'll send this to customers) I'd very much like a prod in the right direction.

  • What version of mongodb was full $text query operator introduced?

    - by Marc Maxson
    Stupid question, right? But the official docs for 'text index' say: http://docs.mongodb.org/manual/core/index-text/ Text Indexes New in version 2.4. To perform queries that access the text index, use the $text query operator. Whereas if you click on the help for searching the index you created with the $text operator, it reads: http://docs.mongodb.org/manual/reference/operator/query/text/#op._S_text $text New in version 2.6. Seems to be 2.4 but still having problems wiht it.

  • why doesn't everyone use RAD tools?

    - by Sorskoot
    RAD tools like Clarion and WinDev claim to be 10x to 20x times faster in development and users of these tools claim the same. If that is thru, why are there so few people using these tools? if an application is made in 40 hours instead of 400 you would make a lot more money, right?
