  • How does a parser LL(*) works?

    - by freezer878
    Hi, I cannot find any complete description about LL() parser, such as ANTLR, on Internet. I'm wondering what is the difference between an LL(k) parser and an LL() one and why they can't support left-recusrive grammars despite their flexibility. Thanks in advance. Fabio.

    - by jestges
    Hi, I want to submit my parent page when I click on submit button of the child page. In my child page I've written my code as string scriptString = "<script language=JavaScript> window.opener.document.forms(0).submit(); </script>"; // ASP.NET 2.0 if (!Page.ClientScript.IsClientScriptBlockRegistered(scriptString)) { Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "script", scriptString); } it is working fine in IE but not working in Firefox. What could be the alternate method for this? Thank in advance

  • Resize iframe to show first element works except in IE 7

    - by Rob Fenwick
    I have two iframes on my home page, the script below is in the head of the page that is being displayed in the iframe, there are several divisions on the page in a container div with an id of 'content', I want to size the iframe on the home page so that just the first div is initially seen and to scroll to see the rest. It is working in all browsers that I have tried except IE 7, I don't care too much about earlier browsers. IE 7 is acting like the page being shown is blank and sizing the iframe to 0 height, can someone tell me why IE 7 is having a problem with it, and failing that how can I get IE 7 to ignore the script? function resizeIframe() { //get the firstChild of a container div with the id 'content' var div01 = document.getElementById("content").firstChild; //find the first element ignoring white spaces and returns while(div01.nodeType!=1){ div01 = div01.nextSibling; } // get the height of first element var boxHeight = div01.clientHeight; //set the height of iframe the id of the iframe is 'news' parent.document.getElementById('news').height = boxHeight; } I have the function called in the body tag. If someone could help me I'd very much appreciate it. The page that it is on is at wsuu.org The version with the script is not up but you can get an idea of what I'm trying to do. Rob

  • Creating PHP strings using other variables...works manually, can't figure out how automatically

    - by Matt
    Hello, I'm trying to get a variable to be formed automatically using data pulled from a mysql database. I know the data is being pulled from the database in some form resembling its original form, but that data does not act the same as data that is manually typed and assigned to a string. For example, if a cell in a mysql table says... I said "goodbye" before I left. She also said "goodbye." ...and I manually copy/paste it and add the necessary escapes... $string1 = " I said \"goodbye\" before I left. She also said \"goodbye.\" "; ...that does not equal... $string1 = $mysqlResultArray['specificCellWithQuoteShownAbove'] Interestingly, if I echo both versions of $string1 and view the output, they appear to be exactly the same. But they do not function the same when put through various functions I've created. The functions only work if I do the manual copy/paste method--which is not what I want, obviously. I'm not sure if it has to do with the line breaks or the escapes--or some combination of the two. But while both strings are superficially the same, they are apparently functionally different and I don't know why. So how can I create $string1 without manually copy/pasting the contents from the mysql entry and instead querying for the data and assigning it to $string1 in such a way that it's exactly functionally equivalent as the manual copy/pasted string?

  • My kernel only works in block (0,0)

    - by ZeroDivide
    I am trying to write a simple matrixMultiplication application that multiplies two square matrices using CUDA. I am having a problem where my kernel is only computing correctly in block (0,0) of the grid. This is my invocation code: dim3 dimBlock(4,4,1); dim3 dimGrid(4,4,1); //Launch the kernel; MatrixMulKernel<<<dimGrid,dimBlock>>>(Md,Nd,Pd,Width); This is my Kernel function __global__ void MatrixMulKernel(int* Md, int* Nd, int* Pd, int Width) { const int tx = threadIdx.x; const int ty = threadIdx.y; const int bx = blockIdx.x; const int by = blockIdx.y; const int row = (by * blockDim.y + ty); const int col = (bx * blockDim.x + tx); //Pvalue stores the Pd element that is computed by the thread int Pvalue = 0; for (int k = 0; k < Width; k++) { Pvalue += Md[row * Width + k] * Nd[k * Width + col]; } __syncthreads(); //Write the matrix to device memory each thread writes one element Pd[row * Width + col] = Pvalue; } I think the problem may have something to do with memory but I'm a bit lost. What should I do to make this code work across several blocks?

  • Cassandra replication system - how it works

    - by inquisitor
    Does cassandra replicates only on write procedure (with choosen consistency level)? Is there any auto-replicate option for absent nodes, if i want symetric data in every node? If I plug in new node to cluster there is no auto replication - how to sync data from others nodes with new one? If I want replication like multimaster (2 nodes) with slave backup (1 node) known from MySQL, what is the proper logic setup and manage that on cassandra (3 nodes)? How about two nodes?

  • DrawString only works in top-left part of form vb.net

    - by WillumMaguire
    Here is my code Public Class Form1 Public MyFormObject As Graphics = Me.CreateGraphics Public objFont = New System.Drawing.Font("arial", 20) Public a, b As Integer Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Randomize() For i = 1 To 10 a = CInt(Int(Rnd() * Me.Width)) b = CInt(Int(Rnd() * Me.Height)) MyFormObject.DrawString("text", objFont, System.Drawing.Brushes.Black, a, b) Next End Sub End Class As you can see, I have one button that draws the string "text" randomly in the form 10 times. My problem is that it will ONLY draw the string in the upper-left portion of the form, roughly 260x260 starting at 0,0. It literally cuts off the text if it goes beyond. Why is this? Shouldn't it work for the entire form?

  • Android URLConnection GET query works WiFi but different response 3G

    - by kisplit
    Hey, I have some code which queries a web server using HTTP GET URLConnection connection = new URL("www.example.com" + "?blah=ok").openConnection(); connection.setRequestProperty("Accept-Charset", "UTF-8"); InputStream http_response = connection.getInputStream(); Now when I run this code while connected to WiFi I get the expected response but when I run this with WiFi disabled I instead seem to get the response of www.example.com without the appended query. Does anyone know why this is happening?

  • jQuery ajax only works first time

    - by Michael Itzoe
    I have a table of data that on a button click certain values are saved to the database, while other values are retrieved. I need the process to be continuous, but I can only get it to work the first time. At first I was using .ajax() and .replaceWith() to rewrite the entire table, but because this overwrites the DOM it was losing events associated with the table. I cannot use .live() because I'm using stopPropagation() and .live() doesn't support it due to event bubbling. I was able to essentially re-bind the click event onto the table within the .ajax() callback, but a second call to the button click event did nothing. I changed the code to use .get() for the ajax and .html() to put the results in the table (the server-side code now returns the complete table sans the <table> tags). I no longer have to rebind the click event to the table, but subsequent clicks to the button still do nothing. Finally, I changed it to .load(), but with the same (non-) results. By "do nothing" I mean while the ajax call is returning the new HTML as expected, it's not being applied to the table. I'm sure it has something to do with altering the DOM, but I thought since I'm only overwriting the table contents and not the table object itself, it should work. Obviously I'm missing something; what is it? Edit: HTML: <table id="table1" class="mytable"> <tr> <td><span id="item1" class="myitem"></span> <td><span id="item2" class="myitem"></span> </tr> </table> <input id="Button1" type="button" value="Submit" /> jQuery: $( "Button1" ).click( function() { $( "table1" ).load( "data.aspx", function( data ) { //... } ); } );

  • Scala :: operator, how it works?

    - by Felix
    Hello Guys, in Scala, I can make a caseclass case class Foo(x:Int) and then put it in a list like so: List(Foo(42)) Now, nothing strange here. The following is strange to me. The operator :: is a function on a list, right? With any function with 1 argument in Scala, I can call it with infix notation. An example is 1 + 2 is a function (+) on the object Int. The class Foo I just defined does not have the :: operator, so how is the following possible: Foo(40) :: List(Foo(2)) ? In scala 2.8 rc1, I get the following output from the interactive prompt: scala> case class Foo(x:Int) defined class Foo scala> Foo(40) :: List(Foo(2)) res2: List[Foo] = List(Foo(40), Foo(2)) scala> I can go on and use it, but if someone can explain it I will be glad :)

  • Changing the cursor in WPF sometimes works, sometimes doesn't

    - by Scott
    On several of my usercontrols, I change the cursor by using this.Cursor = Cursors.Wait; when I click on something. Now I want to do the same thing on a WPF page on a button click. When I hover over my button, the cursor changes to a hand, but when I click it, it doesn't change to the wait cursor. I wonder if this has something to do with the fact that it's a button, or because this is a page and not a usercontrol? This seems like weird behavior.

  • Functioning Socket read no longer works when called in AsyncTask

    - by bibismcbryde
    I'm making an app that sends a string to a server over a socket and then reads the output after the server has processed that data. It worked perfectly when it was my foreground task, but I have since used AsyncTask to show a process dialog while the socket communication runs in the background, and things start breaking after I read the output from the server and then try to close the socket. private class Progressor extends AsyncTask<String, Void, Void> { ProgressDialog dialog; protected void onPreExecute() { dialog = ProgressDialog.show(ClearTalkInputActivity.this, "Loading..", "Analyzing Text", true, false); } protected Void doInBackground(String... strings) { String language = strings[0].toLowerCase(); String the_text = strings[1]; Socket socket = null; DataOutputStream dos = null; DataInputStream dis = null; try { socket = new Socket(my_ip, port); dos = new DataOutputStream(socket.getOutputStream()); dis = new DataInputStream(socket.getInputStream()); dos.writeUTF(language+"****"+the_text); String in = ""; while (in.indexOf("</content>") < 0) { in += dis.readUTF(); } socket.close(); save_str(OUTPUT_KEY, in); } catch (UnknownHostException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } finally { if (socket != null) { try { socket.close(); } catch (IOException e) { e.printStackTrace(); } } } if (dos != null) { try { dos.close(); } catch (IOException e) { e.printStackTrace(); } } if (dis != null) { try { dis.close(); } catch (IOException e) { e.printStackTrace(); } } return null; } protected void onPostExecute() { if (dialog.isShowing()) dialog.dismiss(); startActivity(new Intent (output_intent)); } }

  • Dynamically change embedded video src in IE/Chrome (works in Firefox)

    - by macca1
    I'm trying to dynamically change an embedded video on a page. It's working in Firefox but for some reason it's not working in IE and Chrome (strange combination). Here's the HTML: <object id="viewer" width="575" height="344"> <param name="wmode" value="transparent" /> <param name="movie" value="http://www.youtube.com/v/Lmn94kn08Lw&hl=en&fs=1&color1=0x006699&color2=0x54abd6&rel=0" /> <param name="allowFullScreen" value="true" /> <embed id="embeddedPlayer" src="http://www.youtube.com/v/Lmn94kn08Lw&hl=en&fs=1&color1=0x006699&color2=0x54abd6&rel=0" type="application/x-shockwave-flash" allowfullscreen="true" width="575" height="344" wmode="transparent"></embed> </object> And here's my javascript code. A link is clicked to change the video: $("#video a").click( function() { var videoAddress = $(this).attr("href"); $("#embeddedPlayer").attr("src", videoAddress); return false; // stop the default link so it just reloads in the video player } ); Like I said the videos are changing perfectly in Firefox but in IE and Chrome nothing happens. Any ideas?

  • jquery .get/.post not working on ie 7 or 8, works fine in ff

    - by Samutz
    I have basically this on a page: <script type="text/javascript"> function refresh_context() { $("#ajax-context").html("Searching..."); $.get("/ajax/ldap_search.php", {cn: $("#username").val()}, function(xml) { $("#ajax-context").html($("display", xml).text()); $("#context").val($("context", xml).text()); }, 'xml'); } $(document).ready(function() { $("#username").blur(refresh_context); }); </script> <input type="text" name="username" id="username" maxlength="255" value="" /> <input type="hidden" name="context" id="context" value=""/> <div id="ajax-context"></div> What it should do (and does fine on Firefox) is when you type a username in to the #username field, it will run /ajax/ldap_search.php?cn=$username, which searches our company's ldap for the username and returns it's raw context and a formatted version of the context like this: <result> <display>Staff -&gt; Accounting -&gt; John Smith</display> <context>cn=jsmith,ou=Accounting,ou=Staff,ou=Users,o=MyOrg</context> </result> The formatted version (display) goes to the div #ajax-context and goes to the hidden input #context. (Also, the - are actually - "& g t ;" (without spaces)). However, on IE the div stays stuck on "Searching..." and the hidden input value stays blank. I've tried both .get and .post and neither work. I'm sure it's failing on the .get because if I try this, I don't even get the alert: $.get("/ajax/ldap_search.php", {cn: $("#username").val()}, function() { alert("Check"); }); Also, IE doesn't give me any script errors. Edit: Added "$(document).ready(function() {", the .blur was already in it in my code, but I forgot to include that in my post. Edit 2: The request is being sent and apache2 is receiving it: 10.135.128.96 - - [01/May/2009:10:04:27 -0500] "GET /ajax/ldap_search.php?cn=i_typed_this_in_IE HTTP/1.1" 200 69
