• The sharp decline Statistics of website

  - by Erfan Safarpoor

  My website has had 10 months ago, the statistics are very high. Very high ... But after 10 days of server failure, Marm was 20 times less. I got lost for a long time without making a mistake, do ... I am the source of links that they've hired a writer to pen the final results are seen. But a strange thing: Approximately every two months and was hit again 20 more times and then low again after 10 days! my website url : www.sooran.com (food.sooran.com)

• Moving from XNA/C# to DirectX/C++ quite confused

  - by misiMe

  I made some game with XNA/C# for Windows Phone and Windows 8, since XNA is dead and Visual studio doesn't support it (I have to target Windows Phone 7.1 to build with XNA), I want to start learning something more "consistent in time" and improve my skills. I'm a little confused about the possibilities, because C++/DirectX alone seems difficult, so I found some high-level classes to help: DirectX Toolkit Cocos2D My questions are: What will happen when they will "die" like XNA? Is C++'s approces more "professional" than C#/XNA and why? Is C++'s approces more "portable"? Is C++'s approces more resistant in terms of time? Is there any consideration about DirectX TK and Cocos2D in terms of performance? I ask that because I found that every Game software house in my country looks for skilled C++ programmers.

• Implementing lighting similar as in CubeWorld

  - by Phito

  I am currently writing a voxel engine and my goal is to achieve something looking like CubeWorld. The problem that I am encountering is about lighting. I don't have a lot of knowledge in OpenGL but I don't think lighting in a game like that should be done with glLight. But beside that I have no idea of how to implement it. Here's what I have for the moment (with glLight): Do you have any ideas/link that could give me an idea of how to achieve that? Thanks

• Do I need to store a generic rotation point/radius for rotating around a point other than the origin for object transforms?

  - by Casey

  I'm having trouble implementing a non-origin point rotation. I have a class Transform that stores each component separately in three 3D vectors for position, scale, and rotation. This is fine for local rotations based on the center of the object. The issue is how do I determine/concatenate non-origin rotations in addition to origin rotations. Normally this would be achieved as a Transform-Rotate-Transform for the center rotation followed by a Transform-Rotate-Transform for the non-origin point. The problem is because I am storing the individual components, the final Transform matrix is not calculated until needed by using the individual components to fill an appropriate Matrix. (See GetLocalTransform()) Do I need to store an additional rotation (and radius) for world rotations as well or is there a method of implementation that works while only using the single rotation value?

• Having trouble compiling UnrealScript with defaultproperties

  - by Enchanter

  Have just started scripting in Unreal Script and am following the instructions of the opening chapter of a book on the subject. I have set the development tools up as described in the book such that it is now possible to compile the scripts for UDK before adding them to a level. My issue is: the very first script the book asks you to compile is the following: class AwesomeActor extends Actor placeable; defaultproperties { Begin Object Class=SpriteComponent Name = Sprite Sprite = Texture2D'EditorResources.S_NavP' End Object Components.Add(Sprite) } And when I hit F9 in the compiler I get the following error message: Error, BEGIN OBJECT: Must specify valid name for suboject/copmponent: Begin Object class=SpriteComponent name = Sprite My question: As far as I'm aware I've copied the code from the book veribatim including capital and smaller case letters but I'm getting this error and I was wondering if anyone knew why and if so how I would fix it?

• Combining lists of objects containing lists of objects in c#

  - by Dan H

  The title is a little prosaic, I know. I have 3 classes (Users, Cases, Offices). Users and Cases contain a list of Offices inside of them. I need to compare the Office lists from Users and Cases and if the ID's of Offices match, I need to add those IDs from Cases to the Users. So the end goal is to have the Users class have any Offices that match the Offices in the Cases class. Any ideas? My code (which isnt working) foreach (Users users in userList) foreach (Cases cases in caseList) foreach (Offices userOffice in users.officeList) foreach (Offices caseOffice in cases.officeList) { if (userOffice.ID == caseOffice.ID) users.caseAdminIDList.Add(cases.adminID); }//end foreach //start my data classes class Users { public Users() { List<Offices> officeList = new List<Offices>(); List<int> caseAdminIDList = new List<int>(); ID = 0; }//end constructor public int ID { get; set; } public string name { get; set; } public int adminID { get; set; } public string ADuserName { get; set; } public bool alreadyInDB { get; set; } public bool alreadyInAdminDB { get; set; } public bool deleted { get; set; } public List<int> caseAdminIDList { get; set; } public List<Offices> officeList { get; set; } } class Offices { public int ID { get; set; } public string name { get; set; } } class Users { public Users() { List<Offices> officeList = new List<Offices>(); List<int> caseAdminIDList = new List<int>(); ID = 0; }//end constructor public int ID { get; set; } public string name { get; set; } public int adminID { get; set; } public string ADuserName { get; set; } public bool alreadyInDB { get; set; } public bool alreadyInAdminDB { get; set; } public bool deleted { get; set; } public List<int> caseAdminIDList { get; set; } public List<Offices> officeList { get; set; } }

Create a new list in the newList list of lists if the values in the lists meet the following conditions: multiple lists that match on `myList[i][0]` and `myList[i][7]` but with have (1) sums of `myList[i][3]` and `myList[i][4]` and (2) sums of `myList[i][5]` and `myList[i][6]` that are different from each other are just listed as is in newList if multiple lists match on both `myList[i][0]` (this is the type) and `myList[i][7]` (this is the date) are the same then create a new list for each set of lists with mathcing `myList[i][0]` and `myList[i][7]` that have (1) sums of `myList[i][3]` and `myList[i][4]` and (2) sums of `myList[i][5]` and `myList[i][6]` that are different from the other lists with mathcing `myList[i][0]` and `myList[i][7]`. I also am trying to concatenate `myList[i][1]` separated by a ':' for all those lists with matching `myList[i][0]` and `myList[i][7]` and with sums of `myList[i][3]` + `myList[i][4]` and `myList[i][5]` + `myList[i][6]` that match. So essentially for this case only those lists in `myList` with sums of `myList[i][3]` + `myList[i][4]` and `myList[i][5]` + `myList[i][6]` are different from the other lists are then listed in newList. The above newList illustrates these results I am trying to achieve. If anyone has any ideas how to do this they would be greatly appreciated. Thank you!

• jQuery click event on IE7-8, does not execute on the div, only on its text

  - by user3665301

  I have a problem using the jQuery click event with IE7-8-9. I apply the event on a div. But on these two IE versions, I have to click on the text contained within the div to make the event work. I don't understand because it was still normally working on these versions until I made a few changes (like adding the font css properties) but when I try to delete these changes it stil does not work as I want; Here is a jsfiddle illustrating the situation and its full screen result. http://jsfiddle.net/rC632/ function clickEvent(){ $('.answerDiv').click(function(){ $( "div:animated" ).stop(); if ( idPreviousClick === $(this)[0].id) { } else { if (idPreviousClick != -1) { $("#"+idPreviousClick).css({height:'100px', width:'100px', top:'0', 'line-height': '100px'}); $("#"+idPreviousClick).parent().css({height:'100px', width:'100px', top:'0'}); } $(this).animate({height:'120px', width:'120px', 'line-height': '120px'}); $(this).parent().animate({height:'120px', width:'120px', top:'-10px'}); idPreviousClick = $(this)[0].id; } }); } $(document).ready(function(){ clickEvent(); }); var idPreviousClick = -1; http://jsfiddle.net/rC632/embedded/result/ Could you have any idea of what is missing ?

• verilog / systemverilog -- What is the behavior of blocking statements across two always blocks?

  - by miles.sherman

  I am wondering about the behavior of the below code. There are two always blocks, one is combinational to calculate the next_state signal, the other is sequential which will perform some logic and determine whether or not to shutdown the system. It does this by setting the shutdown_now signal high and then calling state <= next_state. My question is if the conditions become true that the shutdown_now signal is set (during clock cycle n) in a blocking manner before the state <= next_state line, will the state during clock cycle n+1 be SHUTDOWN or RUNNING? In other words, does the shutdown_now = 1'b1 line block across both state machines since the state signal is dependent on it through the next_state determination? enum {IDLE, RUNNING, SHUTDOWN} state, next_state; logic shutdown_now; // State machine (combinational) always_comb begin case (state) IDLE: next_state <= RUNNING; RUNNING: next_state <= shutdown ? SHUTDOWN : RUNNING; SHUTDOWN: next_state <= SHUTDOWN; default: next_state <= SHUTDOWN; endcase end // Sequential Behavior always_ff @ (posedge clk) begin // Some code here if (/*some condition) begin shutdown_now = 1'b0; end else begin shutdown_now = 1'b1; end state <= next_state; end

• Best suited tool to document message processing done in C written program

  - by user3494614

  I am relatively new to UML and it's seems to be very vast I have a small program which basically receives messages on socket and then depending upon message ID embedded as first byte of message it processes the buffer. There are around 5 different message ID which it processes and communicates on another socket and has around 8 major functions. So program in short is like this. I am not pasting entire .c file or main function but just giving some bits and pieces of it so that to get idea of program flow. int main(int argc, char** argv) { register_shared_mem(); listen(); while(get_next_message(buffer)) { switch((msg)(buffer)->id) { case TYPE1: process1(); answer(); ..... } } } I want to document this is pictorial way like for Message type 1 it calls this function which calls another and which calls another. Please let me know any open source tool which will allow me to quickly draw such kind of UML or sequence diagram and will also allow me to write brief description of what each function does? Thanks In Advance

  I have a dataset from which I need to sample. It is set up with an ID field and a year field. I want every record from the most current year and then I want the most current ID's but sampled from every 3rd year going back. The data is ordered by year. For example ID<-rep(1:3, 5) Year<-rep(c(1,2,3,4,5),each=3) df<-data.frame(ID,Year) ID Year 1 1 1 2 2 1 3 3 1 4 1 2 5 2 2 6 3 2 7 1 3 8 2 3 9 3 3 10 1 4 11 2 4 12 3 4 13 1 5 14 2 5 15 3 5 So from this example, I would want to return ID Year 1 1 1 2 2 1 3 3 1 4 1 4 5 2 4 6 3 4 I'm thinking that some combination of duplicated() and which() should get what I want, but the problem is duplicated() just tells if it has been repeated; it doesn't say which record is being repeated. which(duplicated(df$ID)) [1] 4 5 6 7 8 9 10 11 12 13 14 15 This a problem since not every ID exists in every year. Any help would be appreciated. Thanks, Eric

• How to declare class attributes in swift, just like UITableViewCell reuse identifiers?

  - by martin

  I am trying to declare a reuse identifier associated to a UITableView subclass in swift. From my understanding I would like to declare an class stored property (not an instance one) so i have access via: MyCustomTableCell.ReuseIdentifer. Here is what I was trying: class MyCustomTableViewCell : UITableViewCell { class let ReuseIdentifier = "MyCustomTableViewCellReuseIdentifier" } The compiler mentions that class attributes are not supported yet. How to declare such kind of constants associated to a class type in a clean way?

• php - get content from second pair of quotes in string

  - by Aaron Turecki

  I'm trying to get the contents of the second quotes and only the second quotes from a string. Right now I'm able to get the contents of all three quotes. What am I doing wrong? Is it possible to just print the second value in the output array?

• function not working R

  - by user3722828

  I've never programmed before and am trying to learn. I'm following that "coursera" course that I've seen other people post about — a course offered by Johns Hopkins on R programming. Anyway, this was supposed to be my first function. Yet, it doesn't work! But when I type out all the steps individually, it runs just fine... Can anyone tell me why? > pollutantmean <- function(directory, pollutant, id = 1:332){ + x<- list.files("/Users/mike******/Desktop/directory", full.names=TRUE) + y<- lapply(x, read.csv) + z<- do.call(rbind.data.frame, y[id]) + + mean(z$pollutant, na.rm=TRUE) + } > pollutantmean(specdata,nitrate,1:10) [1] NA Warning message: In mean.default(z$pollutant, na.rm = TRUE) : argument is not numeric or logical: returning NA #### > x<- list.files("/Users/mike******/Desktop/specdata",full.names=TRUE) > y<- lapply(x,read.csv) > z<- do.call(rbind.data.frame,y[1:10]) > mean(z$nitrate,na.rm=TRUE) [1] 0.7976266

• CSS Only Selecting Certain Classes

  - by Greg

  Hi I'm working with a Wordpress template. I have a separate template page for the blog section. On the other pages of the site I have class that works fine and looks like this .post header h2 { display:none; } On the blog page, I add this to the CSS and it works as it should #main .post header h2 { display:block; } However if I try that with other classes like #main .wrapper { background-color:#000000; } Nothing happens. I've tried adding !important, I've also tried writing like such body.page-id-15 #main .wrapper { background-color:#000000; } with no luck. Here is a link to the site. http://gregtregunno.ca/news

• Return highest number found in an array of strings

  - by Mdd

  I have an array of objects. The objects have a property called level that is a string which contains a number and is in consistent format. I am trying to find the highest number and return just that one but I seem to be blocked as far as how to proceed from my current code. Here is a fiddle to my current code: http://jsfiddle.net/6sXYR/ Here is my JavaScript: var myArray = [ { color: 'blue', level: 'L1' }, { color: 'red', level: 'L1' }, { color: 'green', level: 'L2' }, { color: 'yellow', level: 'L2' }, { color: 'purple', level: 'L3' } ]; for (var i = 0; i < myArray.length; i++) { console.log( myArray[i].level.substring(1,2) ); }; The result I am trying to get is to return just the number '3' from the example above. The highest number may not always be in the last object in the array, but it will always be in the format of L#.

• Alert on gridview edit based on permission

  - by Vicky

  I have a gridview with edit option at the start of the row. Also I maintain a seperate table called Permission where I maintain user permissions. I have three different types of permissions like Admin, Leads, Programmers. These all three will have access to the gridview. Except admin if anyone tries to edit the gridview on clicking the edit option, I need to give an alert like This row has important validation and make sure you make proper changes. When I edit, the action with happen on table called Application. The table has a column called Comments. Also the alert should happen only when they try to edit rows where the Comments column have these values in them. ManLog datas Funding Approved Exported Applications My try so far. public bool IsApplicationUser(string userName) { return CheckUser(userName); } public static bool CheckUser(string userName) { string CS = ConfigurationManager.ConnectionStrings["ConnectionString"].ToString(); DataTable dt = new DataTable(); using (SqlConnection connection = new SqlConnection(CS)) { SqlCommand command = new SqlCommand(); command.Connection = connection; string strquery = "select * from Permissions where AppCode='Nest' and UserID = '" + userName + "'"; SqlCommand cmd = new SqlCommand(strquery, connection); SqlDataAdapter da = new SqlDataAdapter(cmd); da.Fill(dt); } if (dt.Rows.Count >= 1) return true; else return true; } protected void Details_RowCommand(object sender, GridViewCommandEventArgs e) { string currentUser = HttpContext.Current.Request.LogonUserIdentity.Name; string str = ConfigurationManager.ConnectionStrings["ConnectionString"].ToString(); string[] words = currentUser.Split('\\'); currentUser = words[1]; bool appuser = IsApplicationUser(currentUser); if (appuser) { DataSet ds = new DataSet(); using (SqlConnection connection = new SqlConnection(str)) { SqlCommand command = new SqlCommand(); command.Connection = connection; string strquery = "select Role_Cd from User_Role where AppCode='PM' and UserID = '" + currentUser + "'"; SqlCommand cmd = new SqlCommand(strquery, connection); SqlDataAdapter da = new SqlDataAdapter(cmd); da.Fill(ds); } if (e.CommandName.Equals("Edit") && ds.Tables[0].Rows[0]["Role_Cd"].ToString().Trim() != "ADMIN") { int index = Convert.ToInt32(e.CommandArgument); GridView gvCurrentGrid = (GridView)sender; GridViewRow row = gvCurrentGrid.Rows[index]; string strID = ((Label)row.FindControl("lblID")).Text; string strAppName = ((Label)row.FindControl("lblAppName")).Text; Response.Redirect("AddApplication.aspx?ID=" + strID + "&AppName=" + strAppName + "&Edit=True"); } } } Kindly let me know if I need to add something. Thanks for any suggestions.

• manyToOne is creating new products

  - by user788721

  I am trying to implement Sylius Cart Bundle, but every time I add a product to the cart, a new product is created. This is probably link to my line: cascade: ["persist", "remove"] In my YAML File: Pharmacie\FrontBundle\Entity\CartItem: type: entity table: app_cart_item manyToOne: produit: targetEntity: Pharmacie\FrontBundle\Entity\Product cascade: ["persist", "remove"] joinColumn: name: product_id referencedColumnName: id But if take it off, I get an error: A new entity was found through the relationship 'Pharmacie\FrontBundle\Entity\CartItem#produit' that was not configured to cascade persist operations for entity: 3test2. To solve this issue: Either explicitly call EntityManager#persist() on this unknown entity or configure cascade persist this association in the mapping for example @ManyToOne(..,cascade={"persist"}) According to the doctrine doc, this error occurs when you set a new object. But I am only getting an existing object By ID: $product = $this->getProductRepository()->find($productId); $item->setProduit($product); //this generates the error $item->setUnitPrice(5); //this works fine I don't understand why it's save as a new object. If I use merge instead of persist, I get the same error: A new entity was found through the relationship...

  - by aeroxr1

  I exported a simple animation from Unity3D (version 4.5) in android project. With eclipse I modified the manifest and added another activity. In this activity I put a button that it makes start the animation,and this is the result. The action bar appear in the main activity but it doesn't in the unity's activity :( This is the unity's activity's code : package com.rabidgremlin.tut.redcube; import android.app.NativeActivity; import android.content.res.Configuration; import android.graphics.PixelFormat; import android.os.Bundle; import android.view.KeyEvent; import android.view.MotionEvent; import android.view.View; import android.view.ViewGroup; import android.view.Window; import android.view.WindowManager; import com.unity3d.player.UnityPlayer; public class UnityPlayerNativeActivity extends NativeActivity { protected UnityPlayer mUnityPlayer; // don't change the name of this variable; referenced from native code // Setup activity layout @Override protected void onCreate (Bundle savedInstanceState) { //requestWindowFeature(Window.FEATURE_NO_TITLE); super.onCreate(savedInstanceState); getWindow().takeSurface(null); //setTheme(android.R.style.Theme_NoTitleBar_Fullscreen); getWindow().setFormat(PixelFormat.RGB_565); mUnityPlayer = new UnityPlayer(this); /*if (mUnityPlayer.getSettings ().getBoolean ("hide_status_bar", true)) getWindow ().setFlags (WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); */ setContentView(mUnityPlayer); mUnityPlayer.requestFocus(); } // Quit Unity @Override protected void onDestroy () { mUnityPlayer.quit(); super.onDestroy(); } // Pause Unity @Override protected void onPause() { super.onPause(); mUnityPlayer.pause(); } // eliminiamo questa onResume() e proviamo a modificare la onResume() // Resume Unity @Override protected void onResume() { super.onResume(); mUnityPlayer.resume(); } // inseriamo qualche modifica qui // This ensures the layout will be correct. @Override public void onConfigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig); mUnityPlayer.configurationChanged(newConfig); } // Notify Unity of the focus change. @Override public void onWindowFocusChanged(boolean hasFocus) { super.onWindowFocusChanged(hasFocus); mUnityPlayer.windowFocusChanged(hasFocus); } // For some reason the multiple keyevent type is not supported by the ndk. // Force event injection by overriding dispatchKeyEvent(). @Override public boolean dispatchKeyEvent(KeyEvent event) { if (event.getAction() == KeyEvent.ACTION_MULTIPLE) return mUnityPlayer.injectEvent(event); return super.dispatchKeyEvent(event); } // Pass any events not handled by (unfocused) views straight to UnityPlayer @Override public boolean onKeyUp(int keyCode, KeyEvent event) { return mUnityPlayer.injectEvent(event); } @Override public boolean onKeyDown(int keyCode, KeyEvent event) { return mUnityPlayer.injectEvent(event); } @Override public boolean onTouchEvent(MotionEvent event) { return mUnityPlayer.injectEvent(event); } /*API12*/ public boolean onGenericMotionEvent(MotionEvent event) { return mUnityPlayer.injectEvent(event); } } How can I add the action bar and the style of the first activity to unity's animation activity ?
