  • What's the maximum size Windows 7 allows for ReadyBoost?

    - by ymasood
    I read somewhere the Windows 7 had removed the limit on ReadyBoost from 4GB and now allows an unlimited number of GBs. I would like to reconfirm this as a fact. At present, my Windows 7 RC 7100 allows me a maximum of 4GB on one of my 8GB flash drives (though I've tried to connect two at a time and use 4GB on one and 2GB on another). Thanks!

  • jquery array: find elements that appear twice in the array

    - by tsiger
    For a markup like this: <div id="set1"> <div id="100">a div</div> <div id="101">another div</div> <div id="102">another div 2</div> <div id="120">same div</div> </div> <div id="set2"> <div id="105">a different div> <div id="101">another div</div> <div id="110">more divs</div> <div id="120">same div</div> </div> As you can see both #set1 and #set2 contain 2 divs with the same id (101, 120). Is it possible somehow with jQuery to find the common elements and add a class to the divs in #set1 that have the same id with divs in #set2? In other words after the script run the above code would look like this: <div id="set1"> <div id="100">a div</div> <div id="101" class="added">another div</div> <div id="102">another div 2</div> <div id="120" class="added">same div</div> </div> <div id="set2"> <div id="105">a different div> <div id="101">another div</div> <div id="110">more divs</div> <div id="120">same div</div> </div>

  • Unusual heap size limitations in VS2003 C++

    - by Shane MacLaughlin
    I have a C++ app that uses large arrays of data, and have noticed while testing that it is running out of memory, while there is still plenty of memory available. I have reduced the code to a sample test case as follows; void MemTest() { size_t Size = 500*1024*1024; // 512mb if (Size > _HEAP_MAXREQ) TRACE("Invalid Size"); void * mem = malloc(Size); if (mem == NULL) TRACE("allocation failed"); } If I create a new MFC project, include this function, and run it from InitInstance, it works fine in debug mode (memory allocated as expected), yet fails in release mode (malloc returns NULL). Single stepping through release into the C run times, my function gets inlined I get the following // malloc.c void * __cdecl _malloc_base (size_t size) { void *res = _nh_malloc_base(size, _newmode); RTCCALLBACK(_RTC_Allocate_hook, (res, size, 0)); return res; } Calling _nh_malloc_base void * __cdecl _nh_malloc_base (size_t size, int nhFlag) { void * pvReturn; // validate size if (size > _HEAP_MAXREQ) return NULL; ' ' And (size _HEAP_MAXREQ) returns true and hence my memory doesn't get allocated. Putting a watch on size comes back with the exptected 512MB, which suggests the program is linking into a different run-time library with a much smaller _HEAP_MAXREQ. Grepping the VC++ folders for _HEAP_MAXREQ shows the expected 0xFFFFFFE0, so I can't figure out what is happening here. Anyone know of any CRT changes or versions that would cause this problem, or am I missing something way more obvious?

  • HP p410i array controller - what happens if i add memory?

    - by James
    I have a p410i array controller that only has 256ram. We want to create a raid 5 so we have procured a 512 write back cache module. If we install the write back cache, will this erase the existing raid information. The server currently has 2 disks in raid 1. 6 are spare waiting for an upgrade to create a raid 5. the concern is if we replace/upgrade the memory for the controller, we will wipe the existing production raid 1 array. Thanks in advance.

  • Passing an array of an array of char to a function

    - by L.A. Rabida
    In my program, I may need to load a large file, but not always. So I have defined: char** largefilecontents; string fileName="large.txt"; When I need to load the file, the program calles this function: bool isitok=LoadLargeFile(fileName,largefilecontents); And the function is: bool LoadLargeFile(string &filename, char ** &lines) { if (lines) delete [] lines; ifstream largeFile; #ifdef LINUX largeFile.open(filename.c_str()); #endif #ifdef WINDOWS largeFile.open(filename.c_str(),ios::binary); #endif if (!largeFile.is_open()) return false; lines=new char *[10000]; if (!lines) return false; largeFile.clear(); largeFile.seekg(ios::beg); for (int i=0; i>-1; i++) { string line=""; getline(largeFile,line); if (largeFile.tellg()==-1) break; //when end of file is reached, tellg returns -1 lines[i]=new char[line.length()]; lines[i]=const_cast<char*>(line.c_str()); cout << lines[i] << endl; //debug output } return true; } When I view the debug output of this function, "cout << lines[i] << endl;", it is fine. But when I then check this in the main program like this, it is all messed up: for (i=0; i<10000; i++) cout << largefilecontents[i] << endl; So within the function LoadLargeFile(), the results are fine, but without LoadLargeFile(), the results are all messed up. My guess is that the char ** &lines part of the function isn't right, but I do not know what this should be. Could someone help me? Thank you in advance!

  • Put an array of Objects in nodes of another array of Objects [JAVA]

    - by zengr
    public class hello { public static void main(String[] args) { Object[] newarray = new Object[1]; Object[] obj = new Object[2]; obj[0] = "Number1"; //string value obj[1] = "Number2"; //string value newarray[0] = obj; //this works Object[] tmp_obj = new Object[2]; tmp_obj = newarray[0]; //obviously does not work System.out.println(tmp_obj[0]); //nope System.out.println(tmp_obj[1]); //nope } } So, now if I want to access the values "Number1" and "Number2" which are stored in obj[0] and obj[1]; obj is in newarray[0]. what should I do? Is this a possible? Thanks

    Suppose I have a class public class Foo { public Bar { get; set; } } Then I have another class public class Gloop { public List<Foo> Foos { get; set; } } What's the easiest way to get a List of Foo.Bars? I'm using C# 4.0 and can use Linq if that is the best choice. My first thought was something like

  • Fast and efficient way to read a space separated file of numbers into an array?

    - by John_Sheares
    I need a fast and efficient method to read a space separated file with numbers into an array. The files are formatted this way: 4 6 1 2 3 4 5 6 2 5 4 3 21111 101 3 5 6234 1 2 3 4 2 33434 4 5 6 The first row is the dimension of the array [rows columns]. The lines following contain the array data. The data may also be formatted without any newlines like this: 4 6 1 2 3 4 5 6 2 5 4 3 21111 101 3 5 6234 1 2 3 4 2 33434 4 5 6 I can read the first line and initialize an array with the row and column values. Then I need to fill the array with the data values. My first idea was to read the file line by line and use the split function. But the second format listed gives me pause, because the entire array data would be loaded into memory all at once. Some of these files are in the 100 of MBs. The second method would be to read the file in chunks and then parse them piece by piece. Maybe somebody else has a better a way of doing this?

  • Assigning a 2D array (of pointers) to a variable in an object for access in C++?

    - by MrMormon
    I'm sorry if I didn't pick a descriptive or concise name. A lot of questions sound similar, but I haven't been able to find what I'm looking for. What I want to do is store a 2D array of pointers somewhere and assign a variable in some object to that array to be able to access it. Here's some example code that has the same compile error I'm getting with a bigger project. #include <iostream> using namespace std; struct X{ float * b[8][8]; X(){ *(b[1][5]) = 1; cout << *(b[1][5]) << endl; } void Set(float * c[8][8]){ b = c; cout << *(b[1][5]) << endl; } }; main(){ float * a[8][8]; *(a[1][5]) = 2; X obj; obj.Set(a); } What I want to happen in this code is that an X object starts with its own 2D array, whose value pointed to by b[1][5] should be printed as "1". Then the main method's 2D array, a, is passed to the object's Set() method and assigned to its array variable. The value pointed to by b[1][5] should then be printed as "2". However, I can't figure out what type the Set() parameter, c, should be. I get error: incompatible types in assignment of ‘float* (*)[8]’ to ‘float* [8][8]’ when I try to compile. As for why I want to do this, I'm trying to use an array of pointers to objects, not floats, but it's the same error.

  • Delphi: how to set the length of a RTTI-accessed dynamic array using DynArraySetLength?

    - by conciliator
    I'd like to set the length of a dynamic array, as suggested in this post. I have two classes TMyClass and the related TChildClass defined as TChildClass = class private FField1: string; FField2: string; end; TMyClass = class private FField1: TChildClass; FField2: Array of TChildClass; end; The array augmentation is implemented as var RContext: TRttiContext; RType: TRttiType; Val: TValue; // Contains the TMyClass instance RField: TRttiField; // A field in the TMyClass instance RElementType: TRttiType; // The kind of elements in the dyn array DynArr: TRttiDynamicArrayType; Value: TValue; // Holding an instance as referenced by an array element ArrPointer: Pointer; ArrValue: TValue; ArrLength: LongInt; i: integer; begin RContext := TRTTIContext.Create; try RType := RContext.GetType(TMyClass.ClassInfo); Val := RType.GetMethod('Create').Invoke(RType.AsInstance.MetaclassType, []); RField := RType.GetField('FField2'); if (RField.FieldType is TRttiDynamicArrayType) then begin DynArr := (RField.FieldType as TRttiDynamicArrayType); RElementType := DynArr.ElementType; // Set the new length of the array ArrValue := RField.GetValue(Val.AsObject); ArrLength := 3; // Three seems like a nice number ArrPointer := ArrValue.GetReferenceToRawData; DynArraySetLength(ArrPointer, ArrValue.TypeInfo, 1, @ArrLength); { TODO : Fix 'Index out of bounds' } WriteLn(ArrValue.IsArray, ' ', ArrValue.GetArrayLength); if RElementType.IsInstance then begin for i := 0 to ArrLength - 1 do begin Value := RElementType.GetMethod('Create').Invoke(RElementType.AsInstance.MetaclassType, []); ArrValue.SetArrayElement(i, Value); // This is just a test, so let's clean up immediatly Value.Free; end; end; end; ReadLn; Val.AsObject.Free; finally RContext.Free; end; end. Being new to D2010 RTTI, I suspected the error could depend on getting ArrValue from the class instance, but the subsequent WriteLn prints "TRUE", so I've ruled that out. Disappointingly, however, the same WriteLn reports that the size of ArrValue is 0, which is confirmed by the "Index out of bounds"-exception I get when trying to set any of the elements in the array (through ArrValue.SetArrayElement(i, Value);). Do anyone know what I'm doing wrong here? (Or perhaps there is a better way to do this?) TIA!

  • How can I get a file's size in C?

    - by Nino
    How can I find out the size of a file? I opened with an application written in C. I would like to know the size, because I want to put the content of the loaded file into a string, which I alloc using malloc(). Just writing malloc(10000*sizeof(char)); is IMHO a bad idea.

  • What is the correct terminology to describe a visual display that is about the size of a living room

    - by JW
    I'm thinking that, as flat screens get bigger and cheaper it won't be too long before 'digital wallpaper'-like screens become popular in people's living rooms with a host of applications that could take advantage of this particular screen size/resolution. Is there a proper name for this size of screen? 'Wall Screen' - is too ambiguous 'Massive Screen' - is probably best reserved for something you'd put on the side of a sky scraper 'Small Screen' - nabbed by the mobiles 'Large Screen' - kind of means desktop I'm thinking of the kind of screen used in 'Minority Report'.

  • PHP Array Efficiency and Memory Clarification

    - by CogitoErgoSum
    When declaring an Array in PHP, the index's may be created out of order...I.e Array[1] = 1 Array[19] = 2 Array[4] = 3 My question. In creating an array like this, is the length 19 with nulls in between? If I attempted to get Array[3] would it come as undefined or throw an error? Also, how does this affect memory. Would the memory of 3 index's be taken up or 19? Also currently a developer wrote a script with 3 arrays FailedUpdates[] FailedDeletes[] FailedInserts[] Is it more efficient to do it this way, or do it in the case of an associative array controlling several sub arrays "Failures" array(){ ["Updates"] => array(){ [0] => 12 [1] => 41 } ["Deletes"] => array(){ [0] => 122 [1] => 414 [1] => 43 } ["Inserts"] => array(){ [0] => 12 } }

  • Sort multidimension array in php by more than two fields

    - by Ankita Agrawal
    I want to sort array by two fields. I mean to say I have an array like :- Array ( [0] => Array ( [name] => abc [url] => http://127.0.0.1/abc/img1.png [count] => 69 [img] => accessoire-sets_1.jpg ) [1] => Array ( [name] => abc2 [url] => http://127.0.0.1/abc/img12.png [count] => 73 [img] => ) [2] => Array ( [name] => abc45 [url] => http://127.0.0.1/abc/img122.png [count] => 15 [img] => tomahawk-kopen_1.png ) [3] => Array ( [name] => zyz [url] => http://127.0.0.1/abc/img22.png [count] => 168 [img] => ) [4] => Array ( [name] => lmn [url] => http://127.0.0.1/abc/img1222.png [count] => 10 [img] => ) [5] => Array ( [name] => qqq [url] => http://127.0.0.1/abc/img1222.png [count] => 70 [img] => ) [6] => Array ( [name] => dsa [url] => http://127.0.0.1/abc/img1112.png [count] => 43 [img] => ) [7] => Array ( [name] => wer [url] => http://127.0.0.1/abc/img172.png [count] => 228 [img] => ) [8] => Array ( [name] => hhh [url] => http://127.0.0.1/abc/img126.png [count] => 36 [img] => ) [9] => Array ( [name] => rrrt [url] => http://127.0.0.1/abc/img12.png [count] => 51 [img] => ) [10] => Array ( [name] => yyy [url] => http://127.0.0.1/abc/img12.png [count] => 22 [img] => ) [11] => Array ( [name] => cxz [url] => http://127.0.0.1/abc/img12.png [count] => 41 [img] => ) [12] => Array ( [name] => tre [url] => http://127.0.0.1/abc/img12.png [count] => 32 [img] => ) [13] => Array ( [name] => fds [url] => http://127.0.0.1/abc/img12.png [count] => 10 [img] => ) ) array WITHOUT images (field "img" )should always be placed underneath array WITH images. After this there will be sorted on the amount of products (field count) in the array. Means I have to show sort array first on the basis of img then count. I am using usort( $childLinkCats, 'sortempty' );` function sortempty( $a, $b ) { return empty( $a['img'] ); } it will show array with image value above the one who contains null value. and to sort through count Im using usort($childLinkCats, "_sortByCount"); function _sortByCount($a, $b) { return strnatcmp($a['count'], $b['count']); } It will short by count But I am facing problem that only 1 working is working at a time, but I have to use both, please help me.

  • "Fails to get size of gamma" error when trying to set resolution

  • Fixed window size app development for Mac OS X

    - by Phil
    I am developing a rather eye-candy application which is to be released on Mac App Store. Due to its graphics intensive use, it would save a great deal of time on UI end if the app could be released with a fixed size main frame-dialog. I did try doing a search regarding App Store policies on the matter but could not find anything. Is the distribution of fixed-size frame [productivity] apps are allowed within the App Store if they conform with other design guidelines?

  • Tiling Problem Solutions for Various Size "Dominoes"

    - by user67081
    I've got an interesting tiling problem, I have a large square image (size 128k so 131072 squares) with dimensons 256x512... I want to fill this image with certain grain types (a 1x1 tile, a 1x2 strip, a 2x1 strip, and 2x2 square) and have no overlap, no holes, and no extension past the image boundary. Given some probability for each of these grain types, a list of the number required to be placed is generated for each. Obviously an iterative/brute force method doesn't work well here if we just randomly place the pieces, instead a certain algorithm is required. 1) all 2x2 square grains are randomly placed until exhaustion. 2) 1x2 and 2x1 grains are randomly placed alternatively until exhaustion 3) the remaining 1x1 tiles are placed to fill in all holes. It turns out this algorithm works pretty well for some cases and has no problem filling the entire image, however as you might guess, increasing the probability (and thus number) of 1x2 and 2x1 grains eventually causes the placement to stall (since there are too many holes created by the strips and not all them can be placed). My approach to this solution has been as follows: 1) Create a mini-image of size 8x8 or 16x16. 2) Fill this image randomly and following the algorithm specified above so that the desired probability of the entire image is realized in the mini-image. 3) Create N of these mini-images and then randomly successively place them in the large image. Unfortunately there are some downfalls to this simplification. 1) given the small size of the mini-images, nailing an exact probability for the entire image is not possible. Example if I want p(2x1)=P(1x2)=0.4, the mini image may only give 0.41 as the closes probability. 2) The mini-images create a pseudo boundary where no overlaps occur which isn't really descriptive of the model this is being used for. 3) There is only a fixed number of mini-images so i'm not sure how random this really is. I'm really just looking to brainstorm about possible solutions to this. My main concern is really to nail down closer probabilities, now one might suggest I just increase the mini-image size. Well I have, and it turns out that in certain cases(p(1x2)=p(2x1)=0.5) the mini-image 16x16 isn't even iteratively solvable.. So it's pretty obvious how difficult it is to randomly solve this for anything greater than 8x8 sizes.. So I'd love to hear some ideas. Thanks
