  • Search Box/Transition won't work in Firefox

    - by user2522488
    I disabled the search box on IE, because IE kept centering it over the navigation. It works in Chrome, I'm not sure about opera (and I'm not sure if I care) but it won't work in Firefox. The ease-out timing works in Firefox, but nothing else really works. I've tried other things to work around the issue, but every time I try something different, the search box's positioning gets thrown off. If you look at it in Firefox, it looks fine-- until you click on it to search. http://kissoff.weebly.com/ You can see what the search box is supposed to do if you look at it and click on it in Chrome. I'm sure the positioning is off, I'm not sure (I'm new to css). Any help is appreciated. #search {} #search input[type="text"] { background: url(search-white.png) no-repeat 10px 6px #fcfcfc; border: 1px solid #d1d1d1; position: fixed; margin-left: 350px; margin-right: 0px; margin-top: 0px; color: #bebebe; width: 150px; padding: 6px 15px 6px 35px; -webkit-border-radius: 20px; -moz-border-radius: 20px; border-radius: 20px; text-shadow: 0 2px 3px rgba(0, 0, 0, 0.1); -webkit-box-shadow: 0 1px 3px rgba(0, 0, 0, 0.15) inset; -moz-box-shadow: 0 1px 3px rgba(0, 0, 0, 0.15) inset; box-shadow: 0 1px 3px rgba(0, 0, 0, 0.15) inset; -webkit-transition: all 0.7s ease 0s; -moz-transition: all 0.7s ease 0s; -o-transition: all 0.7s ease 0s; transition: all 0.7s ease 0s; float: right; } #search input[type="text"]:focus { width: 200px; }

  • C# struct with an array

    - by Whitey
    I am making a game using C# with the XNA framework. The player is a 2D soldier on screen and the user is able to fire bullets. The bullets are stored in an array. I have looked into using Lists and arrays for this and I came to the conclusion that an array is a lot better for me, as there will be a lot of bullets firing and being destroyed at once, something that I read Lists don't handle so well. After reading through some posts on the XNA forums, this came to my attention: http://forums.xna.com/forums/p/16037/84353.aspx I have created a struct like so: // Bullets struct Bullet { Vector2 Position; Vector2 Velocity; float Rotation; Rectangle BoundingRect; bool Active; } And I made the array like this: Bullet[] bulletCollection = new Bullet[100]; But when I try to do some code like this: // Fire bullet if (mouseState.LeftButton == ButtonState.Pressed) { for (int i = 0; i < bulletCollection.Length; i++) { if (!bulletCollection[i].Active) { // something } } I get the following error: 'Zombie_Apocalypse.Game1.Bullet.Active' is inaccessible due to its protection level Can anyone lend a hand? I have no idea why this error is popping up, or even if I'm declaring the array properly or anything... as the post on the XNA forums doesn't go into detail about that. Thank you for any help you can provide. :)

  • how do I remove rows/columns from this matrix using python

    - by banditKing
    My matrix looks like this. ['Hotel', ' "excellent"', ' "very good"', ' "average"', ' "poor"', ' "terrible"', ' "cheapest"', ' "rank"', ' "total reviews"'] ['westin', ' 390', ' 291', ' 70', ' 43', ' 19', ' 215', ' 27', ' 813'] ['ramada', ' 136', ' 67', ' 53', ' 30', ' 24', ' 149', ' 49', ' 310 '] ['sutton place', '489', ' 293', ' 106', ' 39', ' 20', ' 299', ' 24', ' 947'] ['loden', ' 681', ' 134', ' 17', ' 5', ' 0', ' 199', ' 4', ' 837'] ['hampton inn downtown', ' 241', ' 166', ' 26', ' 5', ' 1', ' 159', ' 21', ' 439'] ['shangri la', ' 332', ' 45', ' 20', ' 8', ' 2', ' 325', ' 8', ' 407'] ['residence inn marriott', ' 22', ' 15', ' 5', ' 0', ' 0', ' 179', ' 35', ' 42'] ['pan pacific', ' 475', ' 262', ' 86', ' 29', ' 16', ' 249', ' 15', ' 868'] ['sheraton wall center', ' 277', ' 346', ' 150', ' 80', ' 26', ' 249', ' 45', ' 879'] ['westin bayshore', ' 390', ' 291', ' 70', ' 43', ' 19', ' 199', ' 813'] I want to remove the top row and the 0th column from this and create a new matrix. How do I do this? Normally in java or so Id use the following code: for (int y; y< matrix[x].length; y++) for(int x; x < matrix[Y].length; x++) { if(x == 0 || y == 0) { continue } else { new_matrix[x][y] = matrix[x][y]; } } Is there a way such as this in python to iterate and selectively copy elements? Thanks EDIT Im also trying to convert each matrix element from a string to a float as I iterate over the matrix. This my updated modified code based on the answer below. A = [] f = open("csv_test.csv",'rt') try: reader = csv.reader(f) for row in reader: A.append(row) finally: f.close() new_list = [row[1:] for row in A[1:]] l = np.array(new_list) l.astype(np.float32) print l However Im getting an error --> l.astype(np.float32) print l ValueError: setting an array element with a sequence.

  • Custom Font. Keeping the font width same.

    - by user338322
    I am trying to draw a string using quartz 2d. What i am doing is, i am drawing each letter of the string individually, because each letter has special attributes associated with it, by taking each letter into a new string. The string gets printed, but the space between the letters is not uniform. It looks very ugly to read . I read someting about using custom fonts. But i have no Idea, if I can do it!! my code is here. (void) drawRect : (CGRect)rect{ NSString *string=@"My Name Is Adam"; float j=0; const char *charStr=[string cStringUsingEncoding: NSASCIIStringEncoding]; for(int i=0;i { NSString *str=[NSString stringWithFormat:@"%c",charStr[i]]; const char *s=[str cStringUsingEncoding:NSASCIIStringEncoding]; NSLog(@"%s",s); CGContextRef context=[self getMeContextRef]; CGContextSetTextMatrix (context,CGAffineTransformMakeScale(1.0, -1.0)) ; CGContextSelectFont(context, "Arial", 24, kCGEncodingMacRoman); //CGContextSetCharacterSpacing (context, 10); CGContextSetRGBFillColor (context, 0,0,200, 1); CGContextSetTextDrawingMode(context,kCGTextFill); CGContextShowTextAtPoint(context, 80+j,80,s,1); j=j+15; } } In the output 'My Name is Adam' gets printed but the space between the letters is not uniform.!! is there any way to make the space uniform!!!

  • C++ universal data type

    - by Gokul
    I have a universal data type, which is passed by value, but does not maintain the type information. We store only pointers and basic data types(like int, float etc) inside this. Now for the first time, we need to store std::string inside this. So we decided to convert it into std::string* and store it. Then comes the problem of destruction. We don't like to copy the std::string every time. So i am thinking of an approach like this. Say the data type looks like this class Atom { public : enum flags { IS_STRING, IS_EMPTY, HAS_GOT_COPIED, MARKER }; private: void* m_value; std::bitset<MARKER> m_flags; public: ..... Atom( Atom& atm ) { atm.m_flags.set( HAS_GOT_COPIED ); ..... } ..... ~Atom() { if( m_flags.test(IS_STRING) && !m_flags.test(HAS_GOT_COPIED) ) { std::string* val = static_cast<std::string*>(m_value); delete val; } } }; Is this a good approach to find out whether there is no more reference to std::string*? Any comments.. Thanks, Gokul.

  • How to dynamicly build up a gui

    - by InsertNickHere
    Hi there, for the app i am creating i need a lot "option menus". E.g. for the sound file trimming part it would be something like "leadingSilence" / Integer "trailingSilence" / Integer "hold" / Integer. Overall, there are a lot of options of different types (int, float, string), and im thinking about if it is a better way to manualy create a window for each option set, or to dynamicly create them. last one would be quite easy if all types were similar (so i would just add eg spinButtons) I guess but its not. At this time i mange the options with the standard .properties of jave, and there is no need to change. My question is: is there a lib which provides such functionality, or is there a "standard way" to do this? How much work would it be? How to dynamicly create the selection listeners? In could i'd love to have something like: OptionWindow trimmingOptionWindow = createWindowFromOptionSet(OptionManager.getOptions("trimming") ); trimmingOptionWindow.open(); I hope its clear what I mean :)

  • How to implement a multi-threaded asynchronous operation?

    - by drowneath
    Here's how my current approach looks like: // Somewhere in a UI class // Called when a button called "Start" clicked MyWindow::OnStartClicked(Event &sender) { _thread = new boost::thread(boost::bind(&MyWindow::WorkToDo, this)); } MyWindow::WorkToDo() { for(int i = 1; i < 10000000; i++) { int percentage = (int)((float)i / 100000000.f); _progressBar->SetValue(percentage); _statusText->SetText("Working... %d%%", percentage); printf("Pretend to do something useful...\n"); } } // Called on every frame MyWindow::OnUpdate() { if(_thread != 0 && _thread->timed_join(boost::posix_time::seconds(0)) { _progressBar->SetValue(100); _statusText->SetText("Completed!"); delete _thread; _thread = 0; } } But I'm afraid this is far from safe since I keep getting unhandled exception at the end of the program execution. I basically want to separate a heavy task into another thread without blocking the GUI part.

  • custom sorting or ordering a table without resorting the whole shebang

    - by fuugus
    for ten years we've been using the same custom sorting on our tables, i'm wondering if there is another solution which involves fewer updates, especially since today we'd like to have a replication/publication date and would'nt like to have our replication replicate unnecessary entries. i had a look into nested sets, but it does'nt seem to do the job for us. base table: id | a_sort ---+------- 1 10 2 20 3 30 after inserting insert into table (a_sort) values(15) an entry at the second position. id | a_sort ---+------- 1 10 2 20 3 30 4 15 ordering the table with select * from table order by a_sort and resorting all the a_sort entries, updating at least id=(2,3,4) will of course produce the desired output id | a_sort ---+------- 1 10 4 20 2 30 3 40 the column names, the column count, datatypes, a possible join, possible triggers or the way the resorting is done is/are irrelevant to the problem. also we've found some pretty neat ways to do this task fast. only; how the heck can we reduce the updates in the db to 1 or 2 max. seems like an awfully common problem. the captain obvious in me thougth once "use an a_sort float(53), insert using a fixed value of ordervaluefirstentry+abs(ordervaluefirstentry-ordervaluenextentry)/2".. but this would only allow around 1040 "in between" entries - so never resorting seems a bit problematic ;)

  • Storing multiple discarded datas in a single variable using a string accumulator

    - by dan
    For an assignment for my intro to python course, we are to write a program that generates 100 sets of x,y coordinates. X must be a float between -100.0 and 100.0 inclusive, but not 0. Y is Y = ((1/x) * 3070) but if the absolute value of Y is greater than 100, both numbers must be discarded (BUT STORED) and another set generated. The results must be displayed in a table, and then after the table, the discarded results must be shown. The teacher said we should use a "string accumulator" to store the discarded data. This is what I have so far, and I'm stuck at storing the discarded data. # import random.py import random # import math.py import math # define main def main(): x = random.uniform(-100.0, 100.0) while x == 0: x = random.uniform(-100.0, 100.0) y = ((1/x) * 3070) while math.fabs(y) > 100: xDiscarded = yDiscarded = y = ((1/x) * 3070) As you can see, I run into the problem of when abs(y) 100, I'm not too sure how to store the discarded data and let it accumulate every time abs(y) 100. I'm cool with the data being stored as "351.2, 231.1, 152.2" I just don't know how to turn the variable into a string and store it. We haven't learned arrays yet so I can't do that. Any help would be much appreciated. Thanks!

  • Beginner error in CUDA

    - by Dimitri
    Hi folks, first all i want to wish you a merry christmas. I am writing a small program in CUDA and i have the following errors : contraste.cu(167): error: calling a host function from a __device__/__global__ function is not allowed I don't understand why. Can you please help me and show me my errors. It seems that my program is correct. Here is a the bunch of code causing the problems : __global__ void kernel_contraste(float power, unsigned char tab_in[], unsigned char tab_out[], int nbl, int nbc) { int x = threadIdx.x; printf("I am the thread %d\n", x); } Part of my main program : unsigned char *dimg, *dimg_res; ..... cudaMalloc((void **)dimg, h * w * sizeof(char)); cudaMemcpy(dimg, r.data, h*w*sizeof(char), cudaMemcpyHostToDevice); cudaMalloc((void **)dimg_res, h*w*sizeof(char)); dim3 nbThreadparBloc(256); dim3 numblocs(1); kernel_contraste<<<numblocs, nbThreadparBloc >>>(puissance, dimg, dimg_res, h, w); cudaThreadSynchronize(); ..... cudaFree(dimg); cudaFree(dimg_res); The line 167 is the line where i call the printf in function kernel_contraste. For information, this program takes an image as an input( a sun Rasterfile ) and a power then it calculates the contraste of that image. Thanks !!

  • uint64_t has incorrectly reached 18,446,744,071,590,568,320

    - by user3400450
    Whenever I input an age of 65 or less, I get a number somewhere less than 2,100,000. However, when I input an age of 68 or higher, the result is instantly put at 18,446,744,071,590,568,320, which is the maximum value for uint64_t. I have no idea why there is this jump in results. It works fine all the way until about 2,100,000. // How many seconds have I lived? #include <stdio.h> #include <string> #include <cstdint> using namespace std; string addCommas(uint64_t answer); int main () { int seconds = 60, minutes = 60, hours = 24, days = 365; int years; uint64_t secondsLived, secondsAwake; printf("How many years have you lived?

  • Why is joining two vectors simply not working?

    - by Jim
    I have two vectors of MyObj structs. MyObj is defined as follows: struct MyObj { float x, y; unsigned int data[8]; unsigned int tmp[1]; MyObj(const MyObj &m) { x = m.x; y = m.y; tmp[0] = 0; for (int i = 0; i < 8; ++i) { data[i] = m.data[i]; } } }; I then have two vectors... vector<MyObj> v1; vector<MyObj> v2; // both get data eventually. v1.insert(v1.end(), v2.begin(), v2.end()); v2 has 3535004 elements in my experiment. v1 is similarly sized. I've also tried building a new vector and just using .push_back to build it from both vectors. Essentially, when I try to merge the two vectors I just get an error from visual studio saying "Debug error! R6010, abort() has been called". Very non-useful... So my question is: what could be causing this error, and how can I solve it? Thank you

  • Preserving the order of annotations

    - by Ragunath Jawahar
    When obtaining the list of fields using getFields() and getDeclaredFields(), the order of the fields in a Java class is undefined. I need this order in my validation library. Since the order is not preserved (though some claim that the order is preserved in JDK 6 and above but is not guaranteed across VMs). I cannot speculate on this because the order of annotations across fields is absolutely essential for the library. One way to get around this is to have an order or an index attribute in my Annotation. What worries me is that the code could become a bit cumbersome for maintaining in the following case. If the use wants to insert a new annotated field then, he might have to renumber all the other annotations in the class. I could have the order or index as a floating point number - float or double but , it wouldn't look good to have order such as 1, 1.5, 2, etc., What would be an elegant solution for this problem? Here is a example code so that you can get an idea about the problem: @Required @TextRule (minLength = 6, message = "You need at least 6 characters.") private EditText usernameEditText; @Password private EditText passwordEditText; @ConfirmPassword private EditText confirmPasswordEditText; @Email private EditText emailEditText;

  • HTML prevent line break (between two table tags)

    - by arik-so
    Hello, I have following code: <table> <tr> <td>Table 1</td> </tr> </table> <table> <tr> <td>Table 2</td> </tr> </table> Very unfortunately, a line break is inserted between these two tables. I have tried putting them both in a single span and setting the whitespace to nowrap, but at no avail. Please, could you tell me how I can simply put these elements in a single row, without setting the float attribute in CSS and without surrounding each table with a <td> {table} </td> and then putting this in a table row. Thanks a lot in advance. I have asked Google, but it just wouldn't say anything ^^ StackOverflow remained silent so far, too

Of course, I am not looking for only obfuscated code, because I guess that every code could be transformed in a way that it is not readable at all I am more looking for small codes that you can eventually understand, with some clever tricks. I will show them to my students as example of clever things that they should not do (it's always better to show clever examples rather than stupid ones...) Thanks

  • A good way to write unit tests

    - by bobobobo
    So, I previously wasn't really in the practice of writing unit tests - now I kind of am and I need to check if I'm on the right track. Say you have a class that deals with math computations. class Vector3 { public: // Yes, public. float x,y,z ; // ... ctors ... } ; Vector3 operator+( const Vector3& a, const Vector3 &b ) { return Vector3( a.x + b.y /* oops!! hence the need for unit testing.. */, a.y + b.y, a.z + b.z ) ; } There are 2 ways I can really think of to do a unit test on a Vector class: 1) Hand-solve some problems, then hard code the numbers into the unit test and pass only if equal to your hand and hard-coded result bool UnitTest_ClassVector3_operatorPlus() { Vector3 a( 2, 3, 4 ) ; Vector3 b( 5, 6, 7 ) ; Vector3 result = a + b ; // "expected" is computed outside of computer, and // hard coded here. For more complicated operations like // arbitrary axis rotation this takes a bit of paperwork, // but only the final result will ever be entered here. Vector3 expected( 7, 9, 11 ) ; if( result.isNear( expected ) ) return PASS ; else return FAIL ; } 2) Rewrite the computation code very carefully inside the unit test. bool UnitTest_ClassVector3_operatorPlus() { Vector3 a( 2, 3, 4 ) ; Vector3 b( 5, 6, 7 ) ; Vector3 result = a + b ; // "expected" is computed HERE. This // means all you've done is coded the // same thing twice, hopefully not having // repeated the same mistake again Vector3 expected( 2 + 5, 6 + 3, 4 + 7 ) ; if( result.isNear( expected ) ) return PASS ; else return FAIL ; } Or is there another way to do something like this?

  • RegExpValidator never matches

    - by babyangel86
    Hi, I've got a class that's meant to validate input fields to make sure the value is always a decimal. I've tested the regex here: http://livedocs.adobe.com/flex/3/html/help.html?content=validators_7.html, and it looks like it does the right thing, but in my app, I can't seem to get it to match to a number format. Class Definition: public class DecimalValidator { //------------------------------- ATTRIBUTES public var isDecimalValidator:RegExpValidator; //------------------------------- CONSTRUCTORS public function DecimalValidator() { isDecimalValidator = new RegExpValidator(); isDecimalValidator.expression = "^-?(\d+\.\d*|\.\d+)$"; isDecimalValidator.flags = "g"; isDecimalValidator.required = true; isDecimalValidator.property = "text"; isDecimalValidator.triggerEvent = FocusEvent.FOCUS_OUT; isDecimalValidator.noMatchError = "Float Expected"; } } Setting the source here: public function registerDecimalInputValidator(inputBox:TextInput, valArr:Array):void { // Add Validators var dValidator:DecimalValidator = new DecimalValidator(); dValidator.isDecimalValidator.source = inputBox; dValidator.isDecimalValidator.trigger = inputBox; inputBox.restrict = "[0-9].\\.\\-"; inputBox.maxChars = 10; valArr.push(dValidator.isDecimalValidator); } And Calling it here: registerDecimalInputValidator(textInput, validatorArr); Where textInput is an input box created earlier. Clearly I'm missing something simple yet important, but I'm not entirely sure what! Any help would be much appreciated.

  • Using MPI_Type_Vector and MPI_Gather, in C.

    - by Goloneg
    Hi, I am trying to multiply square matrices in parallele with MPI. I use a MPI_Type_vector to send square submatrixes (arrays of float) to the processes, so they can calculate subproducts. Then, for the next iterations, these submatrices are send to neighbours processes as MPI_Type_contiguous (the whole submatrix is sent). This part is working as expected, and local results are corrects. Then, I use MPI_Gather with the contiguous types to send all local results back to the root process. The problem is, the final matrix is build (obviously, by this method) line by line instead of submatrix by submatrix. I wrote an ugly procedure rearranging the final matrix, but I would like to know if there is a direct way of performing the "inverse" operation of sending MPI_Type_vectors (i.e., sending an array of values and directly arranging it in a subarray form in the receiving array). An example, to try and clarify my long text : A[16] and B[16] are 4x4 matrices to be multiplied ; C[16] will contain the result ; 4 processes are used (Pi with i from 0 to 3) : Pi gets two 2x2 submatrices : subAi[4] and subBi[4] ; their product is stored locally in subCi[4]. For instance, P0 gets : subA0[4] containing A[0], A[1], A[4] and A[5] ; subB0[4] containing B[0], B[1], B[4] and B[5]. After everything is calculed, root process gathers all subCi[4]. Then C[16] contains : [ subC0[0], subC0[1], subC0[2], subC0[3], subC1[0], subC1[1], subC1[2], subC1[3], subC2[0], subC2[1], subC2[2], subC2[3], subC3[0], subC3[1], subC3[2], subC3[3]] and I would like it to be : [ subC0[0], subC0[1], subC1[0], subC1[1], subC0[2], subC0[3], subC1[2], subC1[3], subC2[0], subC2[1], subC3[0], subC3[1], subC2[2], subC2[3], subC3[2], subC3[3]] without further operation. Does someone know a way ? Thanks for your advices.

  • SetMatrix() does not copy all values to HLSL

    - by Tili
    Hi, I want to use the contents of a vector of D3DXMatrices to my shader. m_pLightMatrices->SetMatrixArray(&currentLightMatrices[0].m[0][0],0,numLights); As we know the internals of a vector this poses no problems (as it is just a dynamic array). Now when I access this matrix in hlsl to fill up a struct I get this strange behavior: struct LightTest { float3 LightPos; float LightRange; float4 LightDiffuse; float3 LightAtt; }; float4x4 currentLight = gLights[0]; LightTest lt; lt.LightPos = currentLight._m00_m01_m02; //{0,0,0} lt.LightDiffuse = currentLight[1].rgba; //{0,0,0,0} lt.LightRange = currentLight._m03; //this gives me a value lt.LightAtt = currentLight[2].xyz; //{0,0,0} While debugging I see that my matrix is nicely filled with the variables I want. When I try to hardcode check what is in the struct I get all zero's, except the LightRange. As you can see I tried different methods of accessing the float4x4 but without any other results. Why oh why is hlsl not copying all my variables ?

  • Scan file contents into an array of a structure.

    - by ZaZu
    Hello, I have a structure in my program that contains a particular array. I want to scan a random file with numbers and put the contents into that array. This is my code : ( NOTE : This is a sample from a bigger program, so I need the structure and arrays as declared ) The contents of the file are basically : 5 4 3 2 5 3 4 2 #include<stdio.h> #define first 500 #define sec 500 struct trial{ int f; int r; float what[first][sec]; }; int trialtest(trial *test); main(){ trial test; trialtest(&test); } int trialtest(trial *test){ int z,x,i; FILE *fin; fin=fopen("randomfile.txt","r"); for(i=0;i<5;i++){ fscanf(fin,"%5.2f\t",(*test).what[z][x]); } fclose(fin); return 0; } But the problem is, whenever this I run this code, I get this error : (25) : warning 508 - Data of type 'double' supplied where a pointer is required I tried adding do{ for(i=0;i<5;i++){ q=fscanf(fin,"%5.2f\t",(*test).what[z][x]); } }while(q!=EOF); But that didnt work either, it gives the same error. Does anyone have a solution to this problem ?

  • find a duplicate series in SQL

    - by SomeMiscGuy
    I have a table with 3 columns containing a variable number of records based off of the first column which is a foreign key. I am trying to determine if I can detect when there is a duplicate across multiple rows for an entire series declare @finddupseries table ( portid int, asset_id int, allocation float ) ; INSERT INTO @finddupseries SELECT 250, 6, 0.05 UNION ALL SELECT 250, 66, 0.8 UNION ALL SELECT 250, 2, 0.105 UNION ALL SELECT 250, 4, 0.0225 UNION ALL SELECT 250, 5, 0.0225 UNION ALL SELECT 251, 13, 0.6 UNION ALL SELECT 251, 2, 0.3 UNION ALL SELECT 251, 5, 0.1 UNION ALL SELECT 252, 13, 0.8 UNION ALL SELECT 252, 2, 0.15 UNION ALL SELECT 252, 5, 0.05 UNION ALL SELECT 253, 13, 0.4 UNION ALL SELECT 253, 2, 0.45 UNION ALL SELECT 253, 5, 0.15 UNION ALL SELECT 254, 6, 0.05 UNION ALL SELECT 254, 66, 0.8 UNION ALL SELECT 254, 2, 0.105 UNION ALL SELECT 254, 4, 0.0225 UNION ALL SELECT 254, 5, 0.0225 select * from @finddupseries The records for portid 250 and 254 match. Is there any way I can write a query to detect this? edit: yes, the entire series must match. Also, if there was a way to determine which one it DID match would be helpful as the actual table has around 10k records. thanks!
