• Text misaligns in IE

  - by kingrichard2005

  I have a ASP.net web page I'm working with, I didn't create it myself, with the following HTML code: <DIV style="POSITION: absolute; TEXT-ALIGN: center; WIDTH: 1400px; TOP: 60px; LEFT: 125px"> <SPAN style="TEXT-ALIGN: center; FONT-SIZE: xx-large" id=labelInstructions>Some Text: <BR><BR></SPAN> <TABLE style="WIDTH: 1200px" border=1 align=center> <TBODY> <TR> <TD><LABEL style="FONT-SIZE: x-large" for=FileUpload1>ENTER Path: </LABEL><INPUT id=FileUpload1 size=70 type=file name=FileUpload1></TD> </TR> <TR> <TD><SPAN style="COLOR: red; FONT-SIZE: medium" id=fileUploadError><BR><BR></SPAN></TD> </TR> <TR> <TD> <TABLE style="WIDTH: 1200px" border=1> <TBODY> <TR> <TD style="WIDTH: 400px; FONT-SIZE: x-large" vAlign=top align=right>FILE CONTENT INSTRUCTIONS:</TD> <TD style="WIDTH: 850px; FONT-SIZE: x-large" vAlign=top align=left>INSTRUCTION 1<BR>INSTRUCTION 2<BR></TD></TR> <TR><TD></TD></TR> <TR> <TD style="WIDTH: 400px; FONT-SIZE: x-large" vAlign=top align=right>FILE CONTENT EXAMPLE:</TD> <TD style="WIDTH: 850px; FONT-SIZE: x-large" vAlign=top align=left>EXAMPLE 1<BR>EXAMPLE 2<BR><BR></TD> </TR> </TBODY> </TABLE> </TD> </TR> </TBODY> </TABLE> </DIV> When this html is displayed in IE, I notice that the alignment of the text in the cells in the inner table, i.e. the table that is in the third cell of the outer table, is distorted when zooming in and out on it. I have a fixed table setting in pixels instead of percentages, so I don't understand why this is an issue. I want the text in the cells to stay in the same position when zooming. The code must be manipulated from the code behind, so I cannot create a separate CSS file. Any help is appreciated. Here are two examples to illustrate what I'm talking about: Normal zoom at 100%: Zoom at 75%: Notice in the second image the two table cells at the bottom are slightly offset to the left. UPDATE: Yes, I understand, we will be implementing a new system in the near future. Obviously this is old and very non-standard, this was dropped in my lap when I started working with it. And we're coming up with plans for a new system to replace it, in the meantime, this is what I have to deal with.

• jQuery e.stopPropagation() - how to use without breaking dropbox functionality altogether?

  - by Knut Ole

  Short story: stopPropagation() prevents a dropdown menu from closing - which is good. But it also prevents the dropbox from opening next time around - which is bad. Long story: I'm using Twitter-Bootstrap and I've put a search box inside the dropdown menu like so: <div id="search_word_menu" style="position:absolute;right:157px;top:60px;"> <ul class="nav nav-pills"> <li class="dropdown" id="menu200"> <a class="dropdown-toggle btn-inverse" data-toggle="dropdown" style="width:117px;position:relative;left:2px" href="#menu200"> <i class="icon-th-list icon-white"></i> Testing <b class="caret"></b> </a> <ul class="dropdown-menu"> <li><a href="#">Retweets</a></li> <li><a href="#">Favourites</a></li> <li class="divider"></li> <li><a href="#">A list</a></li> <li class="divider"></li> <li><a href="#">A saved search</a></li> <li><a href="#">A saved #hashtag</a></li> <li class="divider"></li> <li> <!-- HERE --> <input id="drop_search" type="text" class="search_box_in_menu" value="Search..."> </li> </ul> </li> </ul> When I click inside the searchbox, the default behaviour is obviously to close the dropdown - but that makes it rather hard to write in a search term. So I've tried with the e.stopPropagation(), which does indeed prevent the dropdown from closing. Then, when I press enter in the searchbox, I'm closing the dropdown with a .toggle() - also seems to work fine. The PROBLEM arises when I want to to it all again, because the e.stopPropagation() has now disabled the dropdown alltogether - ie. when I press the dropdown menu, it doesn't open anymore! This is because of stopPropagation(), no doubt - but how can I resolve this, so that I get the aforementioned functionality, but without breaking the rest altogether? jQuery below: $(document).ready(function() { console.log("document.ready - "); //clearing search box on click $(".search_box_in_menu").click(function(e) { e.stopPropagation(); // works for the specific task console.log(".search_box_in_menu - click."); if($(this).val() == 'Search...') { $(this).val(''); console.log(".search_box_in_menu - value removed."); }; //return false; //this is e.preventDefault() and e.stopPropagation() }); // when pressing enter key in search box $('.search_box_in_menu').keypress(function(e) { var keycode = (e.keyCode ? e.keyCode : e.which); if(keycode == '13') { console.log(".search_box_in_menu - enter-key pressed."); console.log($(this).val()); $(this).closest('.dropdown-menu').toggle(); //works } }); $('.dropdown').click(function() { console.log(".dropdown - click."); $(this).closest('.dropdown-toggle').toggle(); //does nothing }); Would greatly appreciate some help! I'm starting to suspect this might be a bootstrapped-only problem, or at least caused by their implementation - but it's beyond me atm.

• reorder XML elements or set an explicit template with XSLT

  - by Sash

  I tried the solution in my previous question (flattening XML to load via SSIS package), however this isn't working. I now know what I need to do, however I need some guidance on how to do it. So say I have the following XML structure: <person id="1"> <name>John</name> <surname>Smith</surname> <age>25</age> <comment> <comment_id>1</comment_id> <comment_text>Hello</comment_text> </comment> <comment> <comment_id>2</comment_id> <comment_text>Hello again!</comment_text> </comment> <somethingelse> <id>1</id> </somethingelse> <comment> <comment_id>3</comment_id> <comment_text>Third Item</comment_text> </comment> </person> <person id="2"> <name>John</name> <surname>Smith</surname> <age>25</age> <somethingelse> <id>1</id> </somethingelse> </person> ... ... If I am to load this into a SSIS package, as an XML source, what I will essentially get is a table created for each element, as opposed to get a structured table output such as person table (name, surname, age) somethingelse table (id) comment table (comment_id, comment_text) What I end up getting is: person table (person_Id <-- internal SSIS id) name table surname table age table person_name table person_surname table person_comment_comment_id table etc... What I found was that if each element and all inner elements are not in the same format and consistency, i will get the above anomaly which makes it rather complex especially if I am dealing with 80 - 100+ columns. Unfortunately I have no way of modifying the system (Lotus Notes) that produces these reports, so I was wondering whether I may be able to explicitly have an XSLT template that will be able to align each person sub elements (and the sub collection elements such as comments ? Unless there is a quicker way to realign all inner elements. Seems that SSIS XML source requires a very consistent XML file in the sense of: if the name element is in position 1, then all subsequent name elements within person parent have to be in position 1. SSIS seems to pickup the inconsistencies if there are certain elements missing from one parent to another, however, if their ordering is not right (A, B, C)(A, B, C)(A,C,B), it will chuck a massive fuss! All help is appreciated! Thank you in advance.

• trie reg exp parse step over char and continue

  - by forest.peterson

  Setup: 1) a string trie database formed from linked nodes and a vector array linking to the next node terminating in a leaf, 2) a recursive regular expression function that if A) char '*' continues down all paths until string length limit is reached, then continues down remaining string paths if valid, and B) char '?' continues down all paths for 1 char and then continues down remaining string paths if valid. 3) after reg expression the candidate strings are measured for edit distance against the 'try' string. Problem: the reg expression works fine for adding chars or swapping ? for a char but if the remaining string has an error then there is not a valid path to a terminating leaf; making the matching function redundant. I tried adding a 'step-over' ? char if the end of the node vector was reached and then followed every path of that node - allowing this step-over only once; resulted in a memory exception; I cannot find logically why it is accessing the vector out of range - bactracking? Questions: 1) how can the regular expression step over an invalid char and continue with the path? 2) why is swapping the 'sticking' char for '?' resulting in an overflow? Function: void Ontology::matchRegExpHelper(nodeT *w, string inWild, Set<string> &matchSet, string out, int level, int pos, int stepover) { if (inWild=="") { matchSet.add(out); } else { if (w->alpha.size() == pos) { int testLength = out.length() + inWild.length(); if (stepover == 0 && matchSet.size() == 0 && out.length() > 8 && testLength == tokenLength) {//candidate generator inWild[0] = '?'; matchRegExpHelper(w, inWild, matchSet, out, level, 0, stepover+1); } else return; //giveup on this path } if (inWild[0] == '?' || (inWild[0] == '*' && (out.length() + inWild.length() ) == level ) ) { //wild matchRegExpHelper(w->alpha[pos].next, inWild.substr(1), matchSet, out+w->alpha[pos].letter, level, 0, stepover);//follow path -> if ontology is full, treat '*' like a '?' } else if (inWild[0] == '*') matchRegExpHelper(w->alpha[pos].next, '*'+inWild.substr(1), matchSet, out+w->alpha[pos].letter, level, 0, stepover); //keep adding chars if (inWild[0] == w->alpha[pos].letter) //follow self matchRegExpHelper(w->alpha[pos].next, inWild.substr(1), matchSet, out+w->alpha[pos].letter, level, 0, stepover); //follow char matchRegExpHelper(w, inWild, matchSet, out, level, pos+1, stepover);//check next path } } Error Message: +str "Attempt to access index 1 in a vector of size 1." std::basic_string<char,std::char_traits<char>,std::allocator<char> > +err {msg="Attempt to access index 1 in a vector of size 1." } ErrorException Note: this function works fine for hundreds of test strings with '*' wilds if the extra stepover gate is not used Semi-Solved: I place a pos < w->alpha.size() condition on each path that calls w->alpha[pos]... - this prevented the backtrack calls from attempting to access the vector with an out of bounds index value. Still have other issues to work out - it loops infinitely adding the ? and backtracking to remove it, then repeat. But, moving forward now. Revised question: why during backtracking is the position index accumulating and/or not deincrementing - so at somepoint it calls w->alpha[pos]... with an invalid position that is either remaining from the next node or somehow incremented pos+1 when passing upward?

• HTML/JS/CSS issue getting bigger by itself

  - by Azzyh

  Here's the picture to begin with. I have this check box, that when you check, then with jQuery toggle(); it hides that you see in first half of the picture (#writeComment) and shows #SCtryVOTE (what you see in the other half picture, to the right). Now i dont know why but of some reason it expands when its checked, why i dont know, is it because it needs more place than it have or? how do i make this work without having problems when its checked. Here's coding: $('#tryout').click(function () { $('#writeComment').toggle(!$(this).attr('checked')); $('#SCtryVOTE').toggle($(this).attr('checked')); }); the js jquery script part, heres the table and divs HTML part: <input type="checkbox" id="tryout"> <table align="center" width="400" cellpadding="0" cellspacing="1" id="theBoxer"> <tr style="background: #686868;"> <td align="center" valign="top" width="70" height="25" style="border:1px #FFF solid;">Opret</td> <td align="center" valign="top" width="70" height="25" style="border:1px #FFF solid;">Opret</td> </td> </tr> <tr> <td align="left" valign="top" width="70" height="112" style=""> TEST </td> <td align="left" valign="top" width="70" height="112" style=""> <div id="writeComment"> Smid en kommentar:<br> <form action="javascript:DoInsert()" method="post"> <textarea id="kommentar" name="kommentar"></textarea><br /> <input type="hidden" name="fID" id="fID" value="<? echo $_GET["id"]; ?>"> <input type="submit" name="Submit" value="Sæt ind!"> </form> </div> <div id="SCtryVOTE" style="display: none;"> <form onsubmit="if (!this.comment.cleared) clearContents( document.getElementById('comment') ); return true;" action="javascript:DoSCInsert()" method="post"> <textarea onfocus=" javascript:clearContents(this); this.cleared=true;" rows="5" cols="40" id="comment" name="comment" <?php if($vis["username"] == $pusername) { echo "DISABLED"; } ?>>Tryk for at skrive. Skal være detaljeret og grundet.</textarea> <br>Ja: <input type="radio" value="Y" id="SCvoteY" name="vote"></input> Nej: <input type="radio" id="SCvoteN" value="N" name="vote"> </input> <input type="submit" id="SCstem" name="Submit" value="Stem!"> </form> </div> Maybe you need the CSS part too for these two boxes: #writeComment{ position: relative; left: 5px; top: 10px; } #SCtryVOTE{ position: relative; left: 5px; top: 10px; }

• Passing an address inside a WordPress post to a Google Map elsewhere on the Page

  - by ael_ecurai

  Background: My client is building their own WordPress site (using a purchased feature-rich theme), and I'm modifying a child theme as necessary to achieve customizations she wants. The theme comes with a Page template that includes a full-width Google Map across the top, which pulls its marker from a single address set within the Theme Options. It's meant to be used for one main "Contact Us" page. The client's business has several locations, and she wants each location's page to include such a map. (Example linked below.) It seems that the ideal solution would be the ability to specify an address within a shortcode in the Post, and have that set the map marker. Here's how the theme makes the map (where $mapAddress is the address from the Theme Options): <?php $mapAddress = ot_get_option( 'map_address' ); $mapHeight = ot_get_option( 'map_height' ); $mapContent = ot_get_option( 'map_content' ); ?> <section id="block-map-wrapper"> <div id="block-map" class="clearfix"> <script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?sensor=true"></script> <script> jQuery(document).ready(function(){ // Map Options var mapOptions = { zoom: 15, scrollwheel: false, zoomControl: true, zoomControlOptions: { style: google.maps.ZoomControlStyle.SMALL, position: google.maps.ControlPosition.TOP_LEFT }, mapTypeControl: true, scaleControl: false, panControl: false, mapTypeId: google.maps.MapTypeId.ROADMAP }; // The Map Object var map = new google.maps.Map(document.getElementById("map"), mapOptions); var address = ""; var geocoder = new google.maps.Geocoder(); geocoder.geocode({ "address" : "<?php echo $mapAddress; ?>" }, function (results, status) { if (status == google.maps.GeocoderStatus.OK) { address = results[0].geometry.location; map.setCenter(results[0].geometry.location); var marker = new google.maps.Marker({ position: address, map: map, clickable: true, animation: google.maps.Animation.DROP }); var infowindow = new google.maps.InfoWindow({ content: "<?php echo $mapContent; ?>" }); google.maps.event.addListener(marker, "click", function() { infowindow.open(map, marker); }); } }); }); </script> <div id="map" class = "map" style = "width: 100%; height: <?php echo $mapHeight; ?>px"></div> </div><!-- #block-map --> <div class="shadow-bottom"></div> </section><!-- #block-map-wrapper --> Here's a test page using a custom Page template I've created. Right now it's using the same map code as above. I've tried creating a shortcode that takes an address attribute and sets it as $mapAddress, but that didn't work. I believe it's because the map is already loaded by the time the Loop gets parsed. How can I tell Maps to "come back" to the post to get the proper address? My specialty lies in HTML & CSS, but Javascript befuddles me fairly easily, so please be explicit when explaining implementation. Bonus: A further goal is to have the locations' parent Page also include such a map, but have multiple markers representing the multiple locations. When taking more than one location, Google Maps only accepts latitude/longitude. I don't want my client to be concerned with coordinates, so I know there's got to be something I can do with the geocoding service so she can just input a list of addresses instead (into the same, or similar, shortcode solution developed for my main question). But I am extra-clueless about how to do that.

• Slideshow positioning problem

  - by James

  I have a javascript slideshow that works perfectly on Windows 7, Firefox, Chrome, IE 8+ (I don't have the resources to check 6 or 7) and Opera. But I've been told that when on xp with IE 7 the slidshow gets thrown off screen to the right. What could my issue be? Here is my css: #page { width:940px; margin: auto; } gallery { position:relative; padding:0px; margin:5px 0px; width:940px; height:320px; } gallery li { display: block; width:940px; height:320 list-style:none; } And here is my javascript: var galleryId = 'gallery'; var gallery; var galleryImages; var currentImage; var previousImage; var preInitTimer; preInit(); function preInit() { if ((document.getElementById)&&(gallery=document.getElementById(galleryId))) { gallery.style.visibility = "hidden"; if (typeof preInitTimer != 'undefined') clearTimeout(preInitTimer); } else { preInitTimer = setTimeout("preInit()",2); } } function fader(imageNumber,opacity) { var obj=galleryImages[imageNumber]; if (obj.style) { if (obj.style.MozOpacity!=null) { obj.style.MozOpacity = (opacity/100) - .001; } else if (obj.style.opacity!=null) { obj.style.opacity = (opacity/100) - .001; } else if (obj.style.filter!=null) { obj.style.filter = "alpha(opacity="+opacity+")"; } } } function fadeInit() { if (document.getElementById) { preInit(); galleryImages = new Array; var node = gallery.firstChild; while (node) { if (node.nodeType==1) { galleryImages.push(node); } node = node.nextSibling; } for(i=0;i galleryImages[i].style.position='absolute'; galleryImages[i].style.top=0; galleryImages[i].style.zIndex=0; fader(i,0); } gallery.style.visibility = 'visible'; currentImage=0; previousImage=galleryImages.length-1; opacity=100; fader(currentImage,100); window.setTimeout("crossfade(100)", 1000); } } function crossfade(opacity) { if (opacity < 100) { fader(currentImage,opacity); opacity += 9; window.setTimeout("crossfade("+opacity+")", 50); } else { fader(previousImage,0); previousImage=currentImage; currentImage+=1; if (currentImage=galleryImages.length) { currentImage=0; } galleryImages[previousImage].style.zIndex = 0; galleryImages[currentImage].style.zIndex = 100; opacity=0; window.setTimeout("crossfade("+opacity+")", 5000); } } addEvent(window,'load',fadeInit) function addEvent(elm, evType, fn, useCapture) { if (elm.addEventListener){ elm.addEventListener(evType, fn, useCapture); return true; } else if (elm.attachEvent){ var r = elm.attachEvent("on"+evType, fn); return r; } } And ideas?

• [C++] Adding a string or char array to a byte vector

  - by xeross

  I'm currently working on a class to create and read out packets send through the network, so far I have it working with 16bit and 8bit integers (Well unsigned but still). Now the problem is I've tried numerous ways of copying it over but somehow the _buffer got mangled, it segfaulted, or the result was wrong. I'd appreciate if someone could show me a working example. My current code can be seen below. Thanks, Xeross Main #include <iostream> #include <stdio.h> #include "Packet.h" using namespace std; int main(int argc, char** argv) { cout << "#################################" << endl; cout << "# Internal Use Only #" << endl; cout << "# Codename PACKETSTORM #" << endl; cout << "#################################" << endl; cout << endl; Packet packet = Packet(); packet.SetOpcode(0x1f4d); cout << "Current opcode is: " << packet.GetOpcode() << endl << endl; packet.add(uint8_t(5)) .add(uint16_t(4000)) .add(uint8_t(5)); for(uint8_t i=0; i<10;i++) printf("Byte %u = %x\n", i, packet._buffer[i]); printf("\nReading them out: \n1 = %u\n2 = %u\n3 = %u\n4 = %s", packet.readUint8(), packet.readUint16(), packet.readUint8()); return 0; } Packet.h #ifndef _PACKET_H_ #define _PACKET_H_ #include <iostream> #include <vector> #include <stdio.h> #include <stdint.h> #include <string.h> using namespace std; class Packet { public: Packet() : m_opcode(0), _buffer(0), _wpos(0), _rpos(0) {} Packet(uint16_t opcode) : m_opcode(opcode), _buffer(0), _wpos(0), _rpos(0) {} uint16_t GetOpcode() { return m_opcode; } void SetOpcode(uint16_t opcode) { m_opcode = opcode; } Packet& add(uint8_t value) { if(_buffer.size() < _wpos + 1) _buffer.resize(_wpos + 1); memcpy(&_buffer[_wpos], &value, 1); _wpos += 1; return *this; } Packet& add(uint16_t value) { if(_buffer.size() < _wpos + 2) _buffer.resize(_wpos + 2); memcpy(&_buffer[_wpos], &value, 2); _wpos += 2; return *this; } uint8_t readUint8() { uint8_t result = _buffer[_rpos]; _rpos += sizeof(uint8_t); return result; } uint16_t readUint16() { uint16_t result; memcpy(&result, &_buffer[_rpos], sizeof(uint16_t)); _rpos += sizeof(uint16_t); return result; } uint16_t m_opcode; std::vector<uint8_t> _buffer; protected: size_t _wpos; // Write position size_t _rpos; // Read position }; #endif // _PACKET_H_

• Repeater not repeating :0) (asp.net)(vb)

  - by Phil

  Morning stackoverflow, I have a repeater, with the following code in my aspx page; <asp:Repeater ID="Contactinforepeater" runat="server"> <HeaderTemplate> <h1>Contact Information</h1> </HeaderTemplate> <ItemTemplate> <table width="50%"> <tr> <td colspan="2"><%#Container.DataItem("position")%></td> </tr> <tr> <td>Name:</td> <td><%#Container.DataItem("surname")%></td> </tr> <tr> <td>Telephone:</td> <td><%#Container.DataItem("telephone")%></td> </tr> <tr> <td>Fax:</td> <td><%#Container.DataItem("fax")%></td> </tr> <tr> <td>Email:</td> <td><%#Container.DataItem("email")%></td> </tr> </table> </ItemTemplate> <SeparatorTemplate> <br /><hr /><br /> </SeparatorTemplate> </asp:Repeater> Then I have this code in my aspx.vb to get the data; If did = 0 Then s = "sql works on db server" x = New SqlCommand(s, c) x.Parameters.Add("@contentid", Data.SqlDbType.Int) x.Parameters("@contentid").Value = contentid c.Open() r = x.ExecuteReader r.Read() Contactinforepeater.DataSource = r Contactinforepeater.DataBind() End If c.Close() r.Close() If Not did = 0 Then s = "sql works on db server" x = New SqlCommand(s, c) x.Parameters.Add("@contentid", SqlDbType.Int) x.Parameters("@contentid").Value = contentid x.Parameters.Add("@did", SqlDbType.Int) x.Parameters("@did").Value = did c.Open() r = x.ExecuteReader r.Read() Contactinforepeater.DataSource = r Contactinforepeater.DataBind() End If r.Close() c.Close() If 'did' is or is not '0' I still get no data outputted to the page. I just get the 'contact information' h1 header from the header template. I've tested the value of s in sqlsms and it works fine. Position, surname, telephone, fax, email all exist in the db. The particular page I am checking exists and has 1 set of contact information attached. Where am I going wrong? Thanks! ps. Does my syntax appear correct? pps. I am also open to different ways of achieving the same result. I tried via an sqldatasource but ran into problems when using variables as params (there is no option to select them, only controls, querystring etc)

• Rotating images makes ui slow

  i'm trying to implement kind of speedometer. i'm getting informations about rounds per minute, boost and load of an engine over bluetooth and i try to display them on the screen witch 3 arrows witch should point in the right direktion. i tried to use a rotate animation evry time i get data(10-100ms) to setup the arrows. but that makes my ui extremly slow. 500ms to react on a buttonclick. Doese someone know how to make it work better? source code: public void setTacho() { //rotate Tachonadel Rpmcurrentdegree=Rpmcurrentdegree+Rpmdegree; Rpmdegree=((rpms-lastrpm)*RPMtoDegree); RpmAnim=new RotateAnimation((float)Rpmcurrentdegree, (float)Rpmdegree, ivNadel.getWidth()/2, ivNadel.getHeight()/2); RpmAnim.setFillEnabled(true); RpmAnim.setFillAfter(true); ivNadel.setAnimation(RpmAnim); RpmAnim.start(); //rotate Boostbalken currentBoostDegree=currentBoostDegree+BoostDegree; BoostDegree=(boost-lastBoost)*BOOSTtoDegree; //rotate Loadbalken currentLoadDegree=currentLoadDegree+LoadDegree; LoadDegree=(load-lastLoad)*LOADtoDegree; BoostAnim=new RotateAnimation((float)-currentBoostDegree, (float)-BoostDegree, ivBoost.getWidth()/2, ivBoost.getHeight()/2); BoostAnim.setFillEnabled(true); BoostAnim.setFillAfter(true); ivBoost.setAnimation(BoostAnim); BoostAnim.start(); LoadAnim=new RotateAnimation((float)currentLoadDegree, (float)LoadDegree, ivLoad.getWidth()/2, ivLoad.getHeight()/2); LoadAnim.setFillEnabled(true); LoadAnim.setFillAfter(true); ivLoad.setAnimation(LoadAnim); LoadAnim.start(); } when i try to make the rotation only if the values have changed then it works only while they are changing but if they aren't the arrows jump back to the zero position. isnt setfillafter to tell the image that it should hold the new position? code: public void setTacho() { //rotate Tachonadel Rpmcurrentdegree=Rpmcurrentdegree+Rpmdegree; Rpmdegree=((rpms-lastrpm)*RPMtoDegree); if(Rpmdegree!=0) { RpmAnim=new RotateAnimation((float)Rpmcurrentdegree, (float)Rpmdegree, ivNadel.getWidth()/2, ivNadel.getHeight()/2); RpmAnim.setFillEnabled(true); RpmAnim.setFillAfter(true); ivNadel.setAnimation(RpmAnim); RpmAnim.start(); } //rotate Boostbalken currentBoostDegree=currentBoostDegree+BoostDegree; BoostDegree=(boost-lastBoost)*BOOSTtoDegree; //rotate Loadbalken currentLoadDegree=currentLoadDegree+LoadDegree; LoadDegree=(load-lastLoad)*LOADtoDegree; if(BoostDegree!=0) { BoostAnim=new RotateAnimation((float)-currentBoostDegree, (float)-BoostDegree, ivBoost.getWidth()/2, ivBoost.getHeight()/2); BoostAnim.setFillEnabled(true); BoostAnim.setFillAfter(true); ivBoost.setAnimation(BoostAnim); BoostAnim.start(); } if(LoadDegree!=0) { LoadAnim=new RotateAnimation((float)currentLoadDegree, (float)LoadDegree, ivLoad.getWidth()/2, ivLoad.getHeight()/2); LoadAnim.setFillEnabled(true); LoadAnim.setFillAfter(true); ivLoad.setAnimation(LoadAnim); LoadAnim.start(); } } i don't get it =( thx 4 help EDIT: part of the bluetooth Thread that calls the callback while (run) { try { bytes = mmInStream.read(buffer); if (connection.btCallback != null) { connection.btCallback.getData(buffer,bytes); } } catch (IOException e) { break; } the callback methode of the bluetooth thread: public void getData(byte[] bytes, int len) { setTacho(); }

• Suggestions for lightweight, thread-safe scheduler

  - by nirvanai

  I am trying to write a round-robin scheduler for lightweight threads (fibers). It must scale to handle as many concurrently-scheduled fibers as possible. I also need to be able to schedule fibers from threads other than the one the run loop is on, and preferably unschedule them from arbitrary threads as well (though I could live with only being able to unschedule them from the run loop). My current idea is to have a circular doubly-linked list, where each fiber is a node and the scheduler holds a reference to the current node. This is what I have so far: using Interlocked = System.Threading.Interlocked; public class Thread { internal Future current_fiber; public void RunLoop () { while (true) { var fiber = current_fiber; if (fiber == null) { // block the thread until a fiber is scheduled continue; } if (fiber.Fulfilled) fiber.Unschedule (); else fiber.Resume (); //if (current_fiber == fiber) current_fiber = fiber.next; Interlocked.CompareExchange<Future> (ref current_fiber, fiber.next, fiber); } } } public abstract class Future { public bool Fulfilled { get; protected set; } internal Future previous, next; // this must be thread-safe // it inserts this node before thread.current_fiber // (getting the exact position doesn't matter, as long as the // chosen nodes haven't been unscheduled) public void Schedule (Thread thread) { next = this; // maintain circularity, even if this is the only node previous = this; try_again: var current = Interlocked.CompareExchange<Future> (ref thread.current_fiber, this, null); if (current == null) return; var target = current.previous; while (target == null) { // current was unscheduled; negotiate for new current_fiber var potential = current.next; var actual = Interlocked.CompareExchange<Future> (ref thread.current_fiber, potential, current); current = (actual == current? potential : actual); if (current == null) goto try_again; target = current.previous; } // I would lock "current" and "target" at this point. // How can I do this w/o risk of deadlock? next = current; previous = target; target.next = this; current.previous = this; } // this would ideally be thread-safe public void Unschedule () { var prev = previous; if (prev == null) { // already unscheduled return; } previous = null; if (next == this) { next = null; return; } // Again, I would lock "prev" and "next" here // How can I do this w/o risk of deadlock? prev.next = next; next.previous = prev; } public abstract void Resume (); } As you can see, my sticking point is that I cannot ensure the order of locking, so I can't lock more than one node without risking deadlock. Or can I? I don't want to have a global lock on the Thread object, since the amount of lock contention would be extreme. Plus, I don't especially care about insertion position, so if I lock each node separately then Schedule() could use something like Monitor.TryEnter and just keep walking the list until it finds an unlocked node. Overall, I'm not invested in any particular implementation, as long as it meets the requirements I've mentioned. Any ideas would be greatly appreciated. Thanks! P.S- For the curious, this is for an open source project I'm starting at http://github.com/nirvanai/Cirrus

• Drop down list in menu disappears before able to click

  - by user1834770

  I've had quite a search through forums looking for a solution for this, but since I don't know coding I'm not sure what applies to me and what doesn't. So, apologies if this is an often solved problem, but I'll greatly appreciate your help! After much trial and error, I've managed to get a drop down list of pages on my navigation bar; however, when I go to click on a sub-page, the entire menu disappears. I've read through other similar problems where there has been an issue with a margin that's too big, but I think my margins are set to '0'. The blog is at: http://swirlstwirlsblog.blogspot.com.au/ I haven't got content in the sub pages but there are there and linked in the html/javascript widget. I've also looked at it in Chrome, Mozilla, and Safari and it's the same issue. I'm also not sure if this is a javascript, css, or html problem, so please be kind in your responses--I'm only new! Thanks so much to anyone able to help me on this. Here's the script I used in the Widget: <ul id="jsddm"> <li><a href="http://swirlstwirlsblog.blogspot.com.au/">Home</a> <li><a href="http://swirlstwirlsblog.blogspot.com.au/search/label/sparkles">Sparkles</a> </li> <li><a href="http://swirlstwirlsblog.blogspot.com.au/search/label/friendship">Friendship</a> </li> <li><a href="http://swirlstwirlsblog.blogspot.com.au/search/label/humour">Humour</a> </li> <li><a href="">About</a> <ul> <li><a href="http://swirlstwirlsblog.blogspot.com.au/p/about_16.html">Us</a></li> <li><a href="http://swirlstwirlsblog.blogspot.com.au/p/contributers.html">Contributors</a> </li> <li><a href="http://swirlstwirlsblog.blogspot.com.au/p/advertising.html">Advertising</a> </li> <li><a href="http://swirlstwirlsblog.blogspot.com.au/p/privacy-policies.html">Privacy</a></li> <li><a href="http://swirlstwirlsblog.blogspot.com.au/p/contact.html">Contact</a></li> </ul> </li> </li></ul> And here's the html code I put in the template: <pre>#jsddm { margin: 0; padding: 15px; z-index:1000000000; position:relative; } #jsddm li { float: left; list-style: none; font: 12px Tahoma, Arial; } #jsddm li a { display: block; white-space: nowrap; margin:1px 3px; padding: 5px 10px; border-right: 1px color: eeeeee; text-shadow: #ffffff 0 1px 0; color: #363636; font-size: 15px; font-family: crushed; text-decoration: none; vertical-align: middle; } #jsddm li a:hover { background: #C8C8C8; } #jsddm li ul { margin: 0; padding: 0; position: absolute; visibility: hidden; border-top: 1px solid white; } #jsddm li ul li { float: none; display: inline; } #jsddm li ul li a { width: auto; background: #ffffff; } #jsddm li ul li a:hover { background: #eeeeee; }</pre>

• How to hide the div on any click outside

  - by user1720527

  I am starting up on jquery and was tryin to create a simple div hide and show effect. The effects seem to work fine but i need that when user clicks on any other part of the document(i. except the hide/show box), the box should hide back. This is the jsfiddle : http://jsfiddle.net/39DzJ/. I have not styled it properly. I wanted the effects to work first. Can anyone help me out ? Here's the HTML code : <style> #mail_floater { background:#fce8bd; height:88px; width:342px; border:1px solid #b7ad02; border-radius:5px; position:absolute; left:200px; top:50px; border-top:none; z-index:100; padding:0; } #subscribe_user { width:248px; height:16px; border:1px solid #b7ad02; } #cust_care_floater { background:#fce8bd; height:12px; width:108px; border:1px solid #b7ad02; border-radius:2px; border-bottom-left-radius:2px; position:absolute; left:450px; top:30px; border-top:none; z-index:100; clear:both; font-family:Tahoma, Geneva, sans-serif; font-size:10px; font-weight:bold; color:#036f05; box-shadow:1px 1px 3px #ccc inset; } #closer { float:right; margin-right:5px; margin-top:2px; width:19px; height:19px; background:url(../images/close.png) no-repeat; } </style> </head> <body> <a href="#" id="subscribe">Subscribe</a> <a href="#" id="customer_care">Customer care</a> <div id="mail_floater"> <h5>Email</h5> <div id="closer"></div> <div id="email_input"><form><label>Enter E-mail : </label><span><input type="text" id="subscribe_user" /></span> <input type="submit" id="subscribe_me" value="Done" /></form></div> </div> <div id="cust_care_floater"> <span style="padding:0px 10px 0 10px;">033-993-99920</span> </div> </body>?

• Blocking access to websites with objective-C / root privileges in objective-C

  - by kvaruni

  I am writing a program in Objective-C (XCode 3.2, on Snow Leopard) that is capable of either selectively blocking certain sites for a duration or only allow certain sites (and thus block all others) for a duration. The reasoning behind this program is rather simple. I tend to get distracted when I have full internet access, but I do need internet access during my working hours to get to a number of work-related websites. Clearly, this is not a permanent block, but only helps me to focus whenever I find myself wandering a bit too much. At the moment, I am using a Unix script that is called via AppleScript to obtain Administrator permissions. It then activates a number of ipfw rules and clears those after a specific duration to restore full internet access. Simple and effective, but since I am running as a standard user, it gets cumbersome to enter my administrator password each and every time I want to go "offline". Furthermore, this is a great opportunity to learn to work with XCode and Objective-C. At the moment, everything works as expected, minus the actual blocking. I can add a number of sites in a list, specify whether or not I want to block or allow these websites and I can "start" the blocking by specifying a time until which I want to stay "offline". However, I find it hard to obtain clear information on how I can run a privileged Unix command from Objective-C. Ideally, I would like to be able to store information with respect to the Administrator account into the Keychain to use these later on, so that I can simply move into "offline" mode with the convenience of clicking a button. Even more ideally, there might be some class in Objective-C with which I can block access to some/all websites for this particular user without needing to rely on privileged Unix commands. A third possibility is in starting this program with root permissions and the reducing the permissions until I need them, but since this is a GUI application that is nested in the menu bar of OS X, the results are rather awkward and getting it to run each and every time with root permission is no easy task. Anyone who can offer me some pointers or advice? Please, no security-warnings, I am fully aware that what I want to do is a potential security threat.

• Issues with HLSL and lighting

  - by numerical25

  I am trying figure out whats going on with my HLSL code but I have no way of debugging it cause C++ gives off no errors. The application just closes when I run it. I am trying to add lighting to a 3d plane I made. below is my HLSL. The problem consist when my Pixel shader method returns the struct "outColor" . If I change the return value back to the struct "psInput" , everything goes back to working again. My light vectors and colors are at the top of the fx file // PS_INPUT - input variables to the pixel shader // This struct is created and fill in by the // vertex shader cbuffer Variables { matrix Projection; matrix World; float TimeStep; }; struct PS_INPUT { float4 Pos : SV_POSITION; float4 Color : COLOR0; float3 Normal : TEXCOORD0; float3 ViewVector : TEXCOORD1; }; float specpower = 80.0f; float3 camPos = float3(0.0f, 9.0, -256.0f); float3 DirectLightColor = float3(1.0f, 1.0f, 1.0f); float3 DirectLightVector = float3(0.0f, 0.602f, 0.70f); float3 AmbientLightColor = float3(1.0f, 1.0f, 1.0f); /*************************************** * Lighting functions ***************************************/ /********************************* * CalculateAmbient - * inputs - * vKa material's reflective color * lightColor - the ambient color of the lightsource * output - ambient color *********************************/ float3 CalculateAmbient(float3 vKa, float3 lightColor) { float3 vAmbient = vKa * lightColor; return vAmbient; } /********************************* * CalculateDiffuse - * inputs - * material color * The color of the direct light * the local normal * the vector of the direct light * output - difuse color *********************************/ float3 CalculateDiffuse(float3 baseColor, float3 lightColor, float3 normal, float3 lightVector) { float3 vDiffuse = baseColor * lightColor * saturate(dot(normal, lightVector)); return vDiffuse; } /********************************* * CalculateSpecular - * inputs - * viewVector * the direct light vector * the normal * output - specular highlight *********************************/ float CalculateSpecular(float3 viewVector, float3 lightVector, float3 normal) { float3 vReflect = reflect(lightVector, normal); float fSpecular = saturate(dot(vReflect, viewVector)); fSpecular = pow(fSpecular, specpower); return fSpecular; } /********************************* * LightingCombine - * inputs - * ambient component * diffuse component * specualr component * output - phong color color *********************************/ float3 LightingCombine(float3 vAmbient, float3 vDiffuse, float fSpecular) { float3 vCombined = vAmbient + vDiffuse + fSpecular.xxx; return vCombined; } //////////////////////////////////////////////// // Vertex Shader - Main Function /////////////////////////////////////////////// PS_INPUT VS(float4 Pos : POSITION, float4 Color : COLOR, float3 Normal : NORMAL) { PS_INPUT psInput; float4 newPosition; newPosition = Pos; newPosition.y = sin((newPosition.x * TimeStep) + (newPosition.z / 3.0f)) * 5.0f; // Pass through both the position and the color psInput.Pos = mul(newPosition , Projection ); psInput.Color = Color; psInput.ViewVector = normalize(camPos - psInput.Pos); return psInput; } /////////////////////////////////////////////// // Pixel Shader /////////////////////////////////////////////// //Anthony!!!!!!!!!!!

• WCF Timeout issue - should there even be a socket connection?

  - by stiank81

  I have a .Net application which is split into a client and server side. The communication between them is handled using WCF. I'm not using the automagic service references, but instead I've built the connection manually like described in the Screencast by Miguel Castro. Summarized this means that I create a console application on the server side that holds ServiceHost objects for the different services: var myServiceHost = new System.ServiceModel.ServiceHost(typeof(MyService), new Uri("net.tcp://localhost:8002")); myServiceHost.Open(); And on the client side I have service proxies creating channels using the ChannelFactory: IMyService proxy = new ChannelFactory<IMyService>("MyServiceEndpoint").CreateChannel(); The client and server side share the service contract defined in the interface IMyService. And another advantage is that I get minimal App.config files - without all the autogenerated stuff created through the Service References. Example from client side: <?xml version="1.0"?> <configuration> <system.serviceModel> <client> <endpoint address="net.tcp://localhost:8002/MyEndpoint" binding="netTcpBinding" contract="IMyService" name="MyServiceEndpoint"/> </client> </system.serviceModel> </configuration> So - to my problem. I create the proxy once, and it holds a channel all the way through the application. However, if I leave the application without use for a few minutes the channel has timed out, and I get the following exception: The socket connection was aborted. This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue. Local socket timeout was '00:00:59.9979998'. How do I prevent this? I'm assuming I need to specify a higher timeout in my configuration? But I don't want it to ever time out. But on the other hand - I don't want a socket connection! Do I need one? Thought I could go connection less with WCF... What's the permanent solution and best practice on solving this? Set timeout to "never".. Create a new channel for each request? I'm assuming there is some overhead creating the channel?.. Increase the timeout to e.g. 5minutes and create new channel if the connection did timeout? Make it connection less somehow? (Without the overhead of creating channels..) Something else...

• Using native MySQL driver in Erlang

  I am using native MySQL driver (http://code.google.com/p/erlang-mysql-driver/) with mochiweb. When I tried that MySQL driver in shell mode, all woked fine.

• How to use onSensorChanged sensor data in combination with OpenGL

  - by Sponge

  I have written a TestSuite to find out how to calculate the rotation angles from the data you get in SensorEventListener.onSensorChanged(). I really hope you can complete my solution to help people who will have the same problems like me. Here is the code, i think you will understand it after reading it. Feel free to change it, the main idea was to implement several methods to send the orientation angles to the opengl view or any other target which would need it. method 1 to 4 are working, they are directly sending the rotationMatrix to the OpenGl view. all other methods are not working or buggy and i hope someone knows to get them working. i think the best method would be method 5 if it would work, because it would be the easiest to understand but i'm not sure how efficient it is. the complete code isn't optimized so i recommend to not use it as it is in your project. here it is: import java.nio.ByteBuffer;

• Need some help on how to replay the last game of a java maze game

  - by Marty

  Hello, I am working on creating a Java maze game for a project. The maze is displayed on the console as standard output not in an applet. I have created most of hte code I need, however I am stuck at one problem and that is I need a user to be able to replay the last game i.e redraw the maze with the users moves but without any input from the user. I am not sure on what course of action to take, i was thinking about copying each users move or the position of each move into another array, as you can see i have 2 variables which hold the position of the player, plyrX and plyrY do you think copying these values into a new array after each move would solve my problem and how would i go about this? I have updated my code, apologies about the textIO.java class not being present, not sure how to resolve that exept post a link to TextIO.java [TextIO.java][1] My code below is updated with a new array of type char to hold values from the original maze (read in from text file and displayed using unicode characters) and also to new variables c_plyrX and c_plyrY which I am thinking should hold the values of plyrX and plyrY and copy them into the new array. When I try to call the replayGame(); method from the menu the maze loads for a second then the console exits so im not sure what I am doing wrong Thanks public class MazeGame { //unicode characters that will define the maze walls, //pathways, and in game characters. final static char WALL = '\u2588'; //wall final static char PATH = '\u2591'; //pathway final static char PLAYER = '\u25EF'; //player final static char ENTRANCE = 'E'; //entrance final static char EXIT = '\u2716'; //exit //declaring member variables which will hold the maze co-ordinates //X = rows, Y = columns static int entX = 0; //entrance X co-ordinate static int entY = 1; //entrance y co-ordinate static int plyrX = 0; static int plyrY = 1; static int exitX = 24; //exit X co-ordinate static int exitY = 37; //exit Y co-ordinate //static member variables which hold maze values //used so values can be accessed from different methods static int rows; //rows variable static int cols; //columns variable static char[][] maze; //defines 2 dimensional array to hold the maze //variables that hold player movement values static char dir; //direction static int spaces; //amount of spaces user can travel //variable to hold amount of moves the user has taken; static int movesTaken = 0; //new array to hold player moves for replaying game static char[][] mazeCopy; static int c_plyrX; static int c_plyrY; /** userMenu method for displaying the user menu which will provide various options for * the user to choose such as play a maze game, get instructions, etc. */ public static void userMenu(){ TextIO.putln("Maze Game"); TextIO.putln("*********"); TextIO.putln("Choose an option."); TextIO.putln(""); TextIO.putln("1.

• General Questions on setting up Subversion (w/Netbeans) and web development workflow.

  - by Roeland

  Hey guys, I am web developer who currently works mostly on his own but, some projects require outside coding help (my brother.) Anyway, after running in to the problem of "working on the same files" and "saving over each others edits" I decided to research ways to avoid this. Through the help of stackoverflow I decided on subversion. My setup is the following: A windows 2008 server with a clean install. My desktop which is on the local network of the server. Then my brothers desktop which is at his house, not on lan. We both prefer to use netbeans for development. My Questions: How do we set this thing up correctly and most optimally. Here is my current setup and work flow. dev site: in the past I just created sub domains with my web host for test sites (company1.bythepixel.com, company2.bythepixel.com), and editted those sites with netbeans set up having remote sources (ftp). how do i set up my netbeans now? should I set it up with remote sources? I guess I may need to set up a web server on my local server. I'm just not sure of the work flow. When i hit save in netbeans.. will it update the repository.. then do i need to update the site from the repository somehow? live site: when going live, i would just copy all the files from the dev site into the live site. from what i gather i should be able to update the site from the dev repository? Currently I am toying with virtualsvn server (http://www.visualsvn.com/server/) on my local server. It looks like it is set up to use the http protocol. Is there advantages to this or should I consider something that does the file//. Do you recommend any other subversion software that would run on my 2008 box? how will my brother connect? should i set up a permanent vpn from his house to mine? suggestions? (not that important) how do I deal with databases, there anyway to do subversion on database? I know I have a lot of questions and I am trying to read / make sense of the free online subversion book, but its all so overwhelming! Wish there was a small subversion for dummies guide :)
