  • How to troubleshoot rendering differences between Chrome/IE and Firefox? [on hold]

    - by user32548
    I have a personal website and just realized that the display is very different between Firefox (tested 19.0.2 and 25) and Chrome 30.0.1599.101 m Firefox display (this is how I intended it to look. In Chrome & IE9.0 the DIVs all seem to stagger on their own..... ? Im just an amateur and this is my personal blog for fun, Ive never had to troubleshoot a rendering issue like this one. Not sure how to go about doing it? Can Firebug help with determining where layout is inherited from? I have sample HTML if needed but didn't want to cloud up the questions a wall of text.

  • Systray not showing

    - by tnrgus
    I have an application called foo that runs as root. The foo calls system function to execute the other application which show tray icon using Qt. The Systray Icon Example in Qt is working properly in user account but not in root. I run the following command to drop privileges: system(“exec su -l user -c ‘export DISPLAY=:0; /opt/systray &’”); However, the systray icon doesn’t appear in Ubuntu 13.10 & 14.04. Is there any way to display this systray in this case except for the solution that uses a PPA that comes with to re-enable the systray whitelist?

  • Calling a WCF service from another WCF service

    - by ultraman69
    Hi ! I have a WCF service hosted on a windows service on my Server1. It also has IIS on this machine. I call the service from a web app and it works fine. But within this service, I have to call another WCF sevice (also hosted on a windows service) located on Server2. The security credentials are set to "Message" and "Username". I have an error like "SOAP protcol negociation failed". It's a problem with my server certificate public key that doesn't seem to be recognise. However, if I call the service on the Server2 from Server1 in a console app, it works fine. I followed this tutorial to set up my certificates : http://www.codeproject.com/KB/WCF/wcf_certificates.aspx Here's the config file from my service on Server1 that tries to call the second one : <endpoint address="" binding="wsHttpBinding" contract="Microsoft.ServiceModel.Samples.ITraitement" /> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> </service> </services> <client> <endpoint address="http://Server2:8000/servicemodelsamples/service" behaviorConfiguration="myClientBehavior" binding="wsHttpBinding" bindingConfiguration="MybindingCon" contract="Microsoft.ServiceModel.Samples.ICalculator" name=""> <identity> <dns value="ODWCertificatServeur" /> </identity> </endpoint> </client> <bindings> <wsHttpBinding> <binding name="MybindingCon"> <security mode="Message"> <message clientCredentialType="UserName" /> </security> </binding> </wsHttpBinding> </bindings> <behaviors> <serviceBehaviors> <behavior name="ServiceTraitementBehavior"> <serviceMetadata httpGetEnabled="True"/> <serviceDebug includeExceptionDetailInFaults="True" /> </behavior> </serviceBehaviors> <endpointBehaviors> <behavior name="myClientBehavior"> <clientCredentials> <clientCertificate findValue="MachineServiceTraitement" x509FindType="FindBySubjectName" storeLocation="LocalMachine" storeName="My" /> <serviceCertificate> <authentication certificateValidationMode="ChainTrust" revocationMode="NoCheck"/> </serviceCertificate> </clientCredentials> </behavior> </endpointBehaviors> </behaviors> And here's the config file from the web app that calls the service on Server1 : <system.serviceModel> <bindings> <wsHttpBinding> <binding name="WSHttpBinding_ITraitement" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true" allowCookies="false"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> <reliableSession ordered="true" inactivityTimeout="00:10:00" enabled="false" /> <security mode="Message"> <transport clientCredentialType="Windows" proxyCredentialType="None" realm="" /> <message clientCredentialType="Windows" negotiateServiceCredential="true" algorithmSuite="Default" establishSecurityContext="true" /> </security> </binding> </wsHttpBinding> </bindings> <client> <endpoint address="http://localhost:8020/ServiceTraitementPC" binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_ITraitement" contract="ITraitement" name="WSHttpBinding_ITraitement"> </endpoint> </client> Any idea why it works if if I call it in a console app and not from my service ? Maybe it has something to do with the certificateValidationMode="ChainTrust" ?

  • mouse to Three.js world coordinates during TrackballControls

    - by PanChan
    I know there are a lot of answers how to translate the mouse coordinates to the Three.js world coordinates (I prefere this one). But I have troubles on calculating when using TrackballControls. First what I expect to do: I want to add a zoom function to my scene. Not by the mouse wheel, the user should be able to draw a rectangular and by lifting the mouse button, the camera is zooming on this rectangular. I've implemented all and it works, but only when the user didn't rotate/zoom/pan with TrackballControls! If the camera was manipulated, I get wrong coordinates for my drawn rectangular. I really can't figure out why... I only know that it's an issue with TrackballControls, because without them, it works. Does anyone see my mistake? I'm sitting here for two days now and can't find it.... :( var onZoomPlaneMouseDown = function(event){ event.preventDefault(); var plane = document.getElementById("zoomPlane"); var innerPlane = document.getElementById("innerZoomPlane"); var mouseButton = event.keyCode || event.which; mouse.x = ( event.clientX / WIDTH ) * 2 - 1; mouse.y = - ( event.clientY / HEIGHT ) * 2 + 1; if(mouseButton === 1){ var vector = new THREE.Vector3( mouse.x, mouse.y, 0.5 ); projector.unprojectVector( vector, camera ); var dir = vector.sub( camera.position ).normalize(); var distance = - camera.position.z / dir.z; zoomPlaneUpperCorner = camera.position.clone().add( dir.multiplyScalar( distance ) ); innerPlane.style.display = "block"; innerPlane.style.top = event.clientY + "px"; innerPlane.style.left = event.clientX + "px"; } if(mouseButton === 3){ plane.style.display = "none"; innerPlane.style.display = "none"; } }; var onZoomPlaneMouseUp = function(event){ event.preventDefault(); var plane = document.getElementById("zoomPlane"); var innerPlane = document.getElementById("innerZoomPlane"); var mouseButton = event.keyCode || event.which; mouse.x = ( event.clientX / WIDTH ) * 2 - 1; mouse.y = - ( event.clientY / HEIGHT ) * 2 + 1; var vector = new THREE.Vector3( mouse.x, mouse.y, 0.5 ); projector.unprojectVector( vector, camera ); var dir = vector.sub( camera.position ).normalize(); var distance = - camera.position.z / dir.z; zoomPlaneLowerCorner = camera.position.clone().add( dir.multiplyScalar( distance ) ); if(mouseButton === 1){ plane.style.display = "none"; innerPlane.style.display = "none"; var center = new THREE.Vector3(); center.subVectors(zoomPlaneLowerCorner, zoomPlaneUpperCorner); center.multiplyScalar( 0.5 ); center.add(zoomPlaneUpperCorner); var rayDir = new THREE.Vector3(); rayDir.subVectors(center, camera.position ).normalize(); controls.target = center; var height = zoomPlaneUpperCorner.y - zoomPlaneLowerCorner.y; var distanceToCenter = camera.position.distanceTo(center); var minDist = (height / 2) / (Math.tan((camera.fov/2)*Math.PI/180)); camera.translateOnAxis(rayDir, (distanceToCenter - minDist)); } };

  • Rendering a WPF Network Map/Graph layout - Manual? PathListBox? Something Else?

    - by Ben Von Handorf
    I'm writing code to present the user with a simplified network map. At any given time, the map is focused on a specific item... say a router or a server. Based on the focused item, other network entities are grouped into sets (i.e. subnets or domains) and then rendered around the focused item. Lines would represent connections and groups would be visually grouped inside a rectangle or ellipse. Panning and zooming are required features. An item can be selected to display more information in a "properties" style window. An item could also be double-clicked to re-focus the entire network map on that item. At that point, the entire map would be re-calculated. I am using MVVM without any framework, as of yet. Assume the logic for grouping items and determining what should be shown or not is all in place. I'm looking for the best way to approach the UI layout. So far, I'm aware of the following options: Use a canvas for layout (inside a ScrollViewer to handle the panning). Have my ViewModel make use of a Layout Manager type of class, which would handle assigning all the layout properties (Top, Left, etc.). Bind my set of display items to an ItemsControl and use Data Templates to handle the actual rendering. The drawbacks with this approach: Highly manual layout on my part. Lots of calculation. I have to handle item selection manually. Computation of connecting lines is manual. The Pros of this approach: I can draw additional lines between child subnets as appropriate (manually). Additional LayoutManagers could be added later to render the display differently. This could probably be wrapped up into some sort of a GraphLayout control to be re-used. Present the focused item at the center of the display and then use a PathListBox for layout of the additional items. Have my ViewModel expose a simple list of things to be drawn and bind them to the PathListBox. Override the ListBoxItem Template to also create a line geometry from the borders of the focused item (tricky) to the bound item. Use DataTemplates to handle the case where the item being bound is a subnet, in which case we would use another PathListBox in the template to display items inside the subnet. The drawbacks with this approach: Selected Item synchronization across multiple `PathListBox`es. Only one item on the whole graph can be selected at a time, but each child PathListBox maintains its own selection. Also, subnets cannot be selected, but would be selectable without additional work. Drawing the connecting lines is going to be a bit of trickery in the ListBoxItem template, since I need to know the correct side of the focused item to connect to. The pros of this approach: I get to stay out of the layout business, more. I'm looking for any advice or thoughts from others who have encountered similar issues or who have more WPF experience than I. I'm using WPF 4, so any new tricks are legal and encouraged.

  • jquery ui autocomplete positioning wrong

    - by mattRo55
    using jquery ui 1.8 trying autocomplete Everything works apart from that the ui-menu isn't positioned under my input element, but rather in the top left corner. Has anyone come across this problem? Here's my html: <div id="search"> <div id="searchFormWrapper"> <form method="post" name="searchForm" id="searchForm" action="/searchresults"> <label for="searchPhrase" id="searchFor"> Search for</label> <input name="searchPhrase" id="searchPhrase" type="text" /> <label for="searchScope" id="searchIn"> in</label> <select name="searchScope" id="searchScope"> <option value="">All Shops</option> ... </select> <input type="image" name="submitSearch" id="submitSearch" src="/images/buttons/search.gif" alt="Search ..." /> </form> <br class="clear" /> </div> </div> and here's my css: #search { width:100%; margin:0; padding:0; text-align:center; height:36px; line-height:36px; background:#666 url(/images/interface/info_bar_bg.gif) repeat-x top left; overflow:hidden; font-size:12px; } #searchFormWrapper { width:520px; height:36px; overflow:hidden; margin:auto; padding:0; } label#searchFor { display:block; float:left; width:80px; padding:0 5px 0 0; margin:0 0 0 0; text-align:right; } label#searchIn { display:block; float:left; width:20px; padding:0 5px 0 0; margin:0 0 0 0; text-align:right; } #searchPhrase { display:block; float:left; width:120px; margin:7px 0 0 0; padding:0; } #searchScope { display:block; float:left; width:120px; margin:7px 0 0 0; padding:0; } #submitSearch { display:block; float:left; margin:7px 0 0 10px; padding:0; } and here's my javascript: $(document).ready(function() { $("#searchPhrase").autocomplete( { source: "/search?json", minLength: 2 }); });

  • OnSelectedIndexChange only fires on second click when using custom page validation script

    - by Kris P
    Okay.. this is hard to explain, so here it goes. I have an update panel which contains a number of controls. The update panel is triggered by the OnSelectedIndexChanged event of a dropdownlist called: ddlUSCitizenshipStatus. It works as expected when I selected a new item. However, if I leave ddlUSCitizenshipStatus with the default value, and then click "submit" button on the page, the requiredfieldvalidators say there is an error on ddlUSCitizenshipStatus (which it should, as I never selected a value). So I then choose a value, the error message goes away on ddlUSCitizenshipStatus, however the updatepanel does not refresh. I've debugged this locally and the OnSelectedIndexChanged event for ddlUSCitizenshipStatus does not fire. If I choose an item in the ddlUSCitizenshipStatus list a second time, the OnSelectedIndexChanged server event fires and the update panel refreshes and works as expected. The issue is, I have to select an item in ddlUSCitizenshipStatus twice, after failed validation, before the updatepanel it's sitting in updates. The submit button on the page looks like this: <asp:LinkButton ID="btnSubmitPage1" runat="server" CssClass="continueButton" OnClick="btnSubmitPage1_Click" CausesValidation="true" OnClientClick="javascript: return ValidatePage();" /> If I remove my custom OnClientClick script, making the submit button look like this: <asp:LinkButton ID="btnSubmitPage1" runat="server" CssClass="continueButton" OnClick="btnSubmitPage1_Click" CausesValidation="true" ValidationGroup="valGrpAdditionalInformation" /> The dropdownlist, update panel, and reguiredfieldvalidator all work as expected. However, I need to run that custom "ValidatePage()" script when the button is clicked. Below is what my ValidatePage script looks like. I've been troubleshooting this for more hours than I can count.... I hope someone is able to help me. Please let me know if you can figure out why ddlUSCitizenshipStatus doesn't update the updatepanel until the second click after a failed validation. function ValidatePage() { var blnDoPostBack = true; if (typeof(Page_ClientValidate) == 'function' ) { //Client side validation can occur, so lets do it. //Validate each validation group. for( var i = 0; i < Page_ValidationSummaries.length; i++ ) Page_ClientValidate( Page_ValidationSummaries[i].validationGroup.toString() ); //Validate every validation control on the page. for (var i = 0; i < Page_Validators.length; i++) ValidatorValidate(Page_Validators[i]); //Figure out which validation groups have errors, store a list of these validation groups in an array. var aryValGrpsWithErrors = []; for( var i = 0; i < Page_Validators.length; i++ ) { if( !Page_Validators[i].isvalid ) { //This particular validator has thrown an error. //Remeber to not do a postback, as we were able to catch this validation error client side. blnDoPostBack = false; //If we haven't already registered the validation group this erroring validation control is a part of, do so now. if( aryValGrpsWithErrors.indexOf( Page_Validators[i].validationGroup.toString() ) == -1 ) aryValGrpsWithErrors[aryValGrpsWithErrors.length++] = Page_Validators[i].validationGroup.toString(); } } //Now display every validation summary that has !isvalid validation controls in it. for( var i = 0; i < Page_ValidationSummaries.length; i++ ) { if( aryValGrpsWithErrors.indexOf( Page_ValidationSummaries[i].validationGroup.toString() ) != -1 ) { Page_ValidationSummaries[i].style.display = ""; document.getElementById( Page_ValidationSummaries[i].id.toString() + "Wrapper" ).style.display = ""; } else { //The current validation summary does not have any error messages in it, so make sure it's hidden. Page_ValidationSummaries[i].style.display = "none"; document.getElementById( Page_ValidationSummaries[i].id.toString() + "Wrapper" ).style.display = "none"; } } } return blnDoPostBack; }

  • Odd tcp deadlock under windows

    - by John Robertson
    We are moving large amounts of data on a LAN and it has to happen very rapidly and reliably. Currently we use windows TCP as implemented in C++. Using large (synchronous) sends moves the data much faster than a bunch of smaller (synchronous) sends but will frequently deadlock for large gaps of time (.15 seconds) causing the overall transfer rate to plummet. This deadlock happens in very particular circumstances which makes me believe it should be preventable altogether. More importantly if we don't really know the cause we don't really know it won't happen some time with smaller sends anyway. Can anyone explain this deadlock? Deadlock description (OK, zombie-locked, it isn't dead, but for .15 or so seconds it stops, then starts again) The receiving side sends an ACK. The sending side sends a packet containing the end of a message (push flag is set) The call to socket.recv takes about .15 seconds(!) to return About the time the call returns an ACK is sent by the receiving side The the next packet from the sender is finally sent (why is it waiting? the tcp window is plenty big) The odd thing about (3) is that typically that call doesn't take much time at all and receives exactly the same amount of data. On a 2Ghz machine that's 300 million instructions worth of time. I am assuming the call doesn't (heaven forbid) wait for the received data to be acked before it returns, so the ack must be waiting for the call to return, or both must be delayed by something else. The problem NEVER happens when there is a second packet of data (part of the same message) arriving between 1 and 2. That part very clearly makes it sound like it has to do with the fact that windows TCP will not send back a no-data ACK until either a second packet arrives or a 200ms timer expires. However the delay is less than 200 ms (its more like 150 ms). The third unseemly character (and to my mind the real culprit) is (5). Send is definitely being called well before that .15 seconds is up, but the data NEVER hits the wire before that ack returns. That is the most bizarre part of this deadlock to me. Its not a tcp blockage because the TCP window is plenty big since we set SO_RCVBUF to something like 500*1460 (which is still under a meg). The data is coming in very fast (basically there is a loop spinning out data via send) so the buffer should fill almost immediately. According to msdn the buffer being full and at least one pending send should cause the data to be sent (though in another place it mentions that there various "heuristics" used in deciding when a send hits the wire). Anway, why the sender doesn't actually send more data during that .15 second pause is the most bizarre part to me. The information above was captured on the receiving side via wireshark (except of course the socket.recv return times which were logged in a text file). We tried changing the send buffer to zero and turning off Nagle on the sender (yes, I know Nagle is about not sending small packets - but we tried turning Nagle off in case that was part of the unstated "heuristics" affecting whether the message would be posted to the wire. Technically microsoft's Nagle is that a small packet isn't sent if the buffer is full and there is an outstanding ACK, so it seemed like a possibility).

  • Calling the same xsl:template for different node names of the same complex type

    - by CraftyFella
    Hi, I'm trying to keep my xsl DRY and as a result I wanted to call the same template for 2 sections of an XML document which happen to be the same complex type (ContactDetails and AltContactDetails). Given the following XML: <?xml version="1.0" encoding="UTF-8"?> <RootNode> <Name>Bob</Name> <ContactDetails> <Address> <Line1>1 High Street</Line1> <Town>TownName</Town> <Postcode>AB1 1CD</Postcode> </Address> <Email>[email protected]</Email> </ContactDetails> <AltContactDetails> <Address> <Line1>3 Market Square</Line1> <Town>TownName</Town> <Postcode>EF2 2GH</Postcode> </Address> <Email>[email protected]</Email> </AltContactDetails> </RootNode> I wrote an XSL Stylesheet as follows: <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:template match="/"> <PersonsName> <xsl:value-of select="RootNode/Name"/> </PersonsName> <xsl:call-template name="ContactDetails"> <xsl:with-param name="data"><xsl:value-of select="RootNode/ContactDetails"/></xsl:with-param> <xsl:with-param name="elementName"><xsl:value-of select="'FirstAddress'"/></xsl:with-param> </xsl:call-template> <xsl:call-template name="ContactDetails"> <xsl:with-param name="data"><xsl:value-of select="RootNode/AltContactDetails"/></xsl:with-param> <xsl:with-param name="elementName"><xsl:value-of select="'SecondAddress'"/></xsl:with-param> </xsl:call-template> </xsl:template> <xsl:template name="ContactDetails"> <xsl:param name="data"></xsl:param> <xsl:param name="elementName"></xsl:param> <xsl:element name="{$elementName}"> <FirstLine> <xsl:value-of select="$data/Address/Line1"/> </FirstLine> <Town> <xsl:value-of select="$data/Address/Town"/> </Town> <PostalCode> <xsl:value-of select="$data/Address/Postcode"/> </PostalCode> </xsl:element> </xsl:template> </xsl:stylesheet> When i try to run the style sheet it's complaining to me that I need to: To use a result tree fragment in a path expression, either use exsl:node-set() or specify version 1.1 I don't want to go to version 1.1.. So does anyone know how to get the exsl:node-set() working for the above example? Or if someone knows of a better way to apply the same template to 2 different sections then that would also really help me out? Thanks Dave

  • Running 32 bit assembly code on a 64 bit Linux & 64 bit Processor : Explain the anomaly.

    - by claws
    Hello, I'm in an interesting problem.I forgot I'm using 64bit machine & OS and wrote a 32 bit assembly code. I don't know how to write 64 bit code. This is the x86 32-bit assembly code for Gnu Assembler (AT&T syntax) on Linux. //hello.S #include <asm/unistd.h> #include <syscall.h> #define STDOUT 1 .data hellostr: .ascii "hello wolrd\n"; helloend: .text .globl _start _start: movl $(SYS_write) , %eax //ssize_t write(int fd, const void *buf, size_t count); movl $(STDOUT) , %ebx movl $hellostr , %ecx movl $(helloend-hellostr) , %edx int $0x80 movl $(SYS_exit), %eax //void _exit(int status); xorl %ebx, %ebx int $0x80 ret Now, This code should run fine on a 32bit processor & 32 bit OS right? As we know 64 bit processors are backward compatible with 32 bit processors. So, that also wouldn't be a problem. The problem arises because of differences in system calls & call mechanism in 64-bit OS & 32-bit OS. I don't know why but they changed the system call numbers between 32-bit linux & 64-bit linux. asm/unistd_32.h defines: #define __NR_write 4 #define __NR_exit 1 asm/unistd_64.h defines: #define __NR_write 1 #define __NR_exit 60 Anyway using Macros instead of direct numbers is paid off.

So when it appear on screen each character is separate like this. ? ?? ? ? ?? . Because i read character by character I want it to appear in proper form like this ??????? So how can i do this. Is there font rendering required. If yes then how can i do it or any other method please hep me. Thanks

  • Actionscript 3: Monitoring the activity level for multiple Microphones doesn't seem to work.

    - by Dave
    For a project I want to show all available webcams and microphones, so that the user can easily select whichever webcam/microphone combination they prefer. I run into an issue with the microphones listing though. Each microphone is listed with an activity animation and it's name. I am able to list all Microphones just fine (using the Microphone.names Array), but it seems like I can only get the activity viewer to work for one microphone. The other microphones show up with '-1' activity, which (as far as I know) is Flex for 'present, but not in use'. When unplugging the microphone that does show activity, the next one (in my case, the mic-in line on my motherboard) shows up with '0' activity (it's not connected, so that makes sense). During my testing I have a total of 3 microphones available, the not-connected onboard mic-in port, and two connected microphones. For testing purposes I use a timer that traces the current microphone activity each 100ms and the graph is also shown. It does not seem to matter what default microphone I set via flash' settings panel. The code I've only attached the revelant code snippets below to make it easier for you to read through them. Please let me know if you prefer the entire code. Main application.mxml Note: cont is a VBox. i is defined before this code snippet. var mics:Array = Microphone.names; for(i=0; i < mics.length; i++){ var mic:settingsMicEntry = new assets.settingsMicEntry; mic.d = {name: mics[i], index: i}; cont.addChild(mic); } assets/settingsMicEntry.mxml timer is defined before this code snippet. the SoundTransform is added to silence local microphone playback. Excluding this code does not solve the problem, sadly (I've tried). display is an MXML Canvas object. mic = Microphone.getMicrophone(d.index); if(mic){ // Temporary: The Microphones' visualizer var bar:Box = new Box(); bar.y = 50; bar.height = 0; bar.width = 66; bar.setStyle("backgroundColor", 0x003300); display.addChild(bar); var tf:SoundTransform = new SoundTransform(0); mic.setLoopBack(true); mic.soundTransform = tf; timer = new Timer(100); timer.addEventListener(TimerEvent.TIMER, function(e:TimerEvent):void{ var h:int = Math.floor((display.height/100)*mic.activityLevel); bar.height = (h>-1) ? h : 0; bar.y = (h>-1) ? display.height-h : display.height; trace('TIMER: '+h+' from '+d.name); }); timer.start(); } I'm pulling my hear out here, so any help is much appreciated! Thanks, -Dave Ps.: Pardon the messiness of the code!

It looks like ie9 is completing ignoring the stylesheet, but in error checking and clicking ie9 direct mode, it shows up however VERY ugly with huge nasty white borders around the links! Please see my code: <div class="flyout"> <ul> <!--START: CATEGORIES--> <!--START: CATEGORY_FORMAT--> <li><a href="view_category.asp?cat=CATID">&nbsp;CATEGORY</a> <!--END: CATEGORY_FORMAT--> <ul><!--START: SUB_CATEGORY_FORMAT--> <li><a href="view_category.asp?cat=CATID">&nbsp;CATEGORY</a></li> <!--END: SUB_CATEGORY_FORMAT--></ul> <!--END: CATEGORIES--> </li> </ul> </div> AND CSS .flyout { width: 130px; height: auto; position:relative; margin: -10 0; padding: 0; z-index:10000; } .flyout ul li a { display:block; text-decoration:none; color: #fff; width: 130px; border: solid; border-color: #000; border-width: 0 0 0 5px; text-align:left; font-size:12px; line-height: 25px; } .flyout ul { padding:0px; list-style-type: none; } .flyout ul li { float:left; margin-right:1px; position:relative; } .flyout ul li ul { display: none; } .flyout ul li:hover a { border: solid; border-color: #fff; border-width: 0 2 0 5px; color: #60dfe5; } .flyout ul li:hover ul { display:block; position:absolute; top:0; left:130px; width:10px; } .flyout ul li:hover ul li a.hide { background:#000; color:#fff; } .flyout ul li:hover ul li:hover a.hide {width:180px;} .flyout ul li:hover ul li ul {display: none;} .flyout ul li:hover ul li a { display:block; background:#000; color:#60dfe5; width:200px; } .flyout ul li:hover ul li a:hover { background:#000; color:#fff; } Thanks, Brandon

  • Multi-threaded .NET application blocks during file I/O when protected by Themida

    - by Erik Jensen
    As the title says I have a .NET application that is the GUI which uses multiple threads to perform separate file I/O and notice that the threads occasionally block when the application is protected by Themida. One thread is devoted to reading from serial COM port and another thread is devoted to copying files. What I experience is occasionally when the file copy thread encounters a network delay, it will block the other thread that is reading from the serial port. In addition to slow network (which can be transient), I can cause the problem to happen more frequently by making a PathFileExists call to a bad path e.g. PathFileExists("\\\\BadPath\\file.txt"); The COM port reading function will block during the call to ReadFile. This only happens when the application is protected by Themida. I have tried under WinXP, Win7, and Server 2012. In a streamlined test project, if I replace the .NET application with a MFC unmanaged application and still utilize the same threads I see no issue even when protected with Themida. I have contacted Oreans support and here is their response: The way that a .NET application is protected is very different from a native application. To protect a .NET application, we need to hook most of the file access APIs in order to "cheat" the .NET Framework that the application is protected. I guess that those special hooks (on CreateFile, ReadFile...) are delaying a bit the execution in your application and the problem appears. We did a test making those hooks as light as possible (with minimum code on them) but the problem still appeared in your application. The rest of software protectors that we tried (like Enigma, Molebox...) also use a similar hooking approach as it's the only way to make the .NET packed file to work. If those hooks are not present, the .NET Framework will abort execution as it will see that the original file was tampered (due to all Microsoft checks on .NET files) Those hooks are not present in a native application, that's why it should be working fine on your native application. Oreans support tried other software protectors such as Enigma Protector, Engima VirtualBox, and Molebox and all exhibit the exact same problem. What I have found as a work around is to separate out the file copy logic (where the file exists call is being made) to be performed in a completely separate process. I have experimented with converting the thread functions from unmanaged C++ to VB.NET equivalents (PathFileExists - System.IO.File.Exists and CreateFile/ReadFile - System.IO.Ports.SerialPort.Open/Read) and still see the same serial port read blocked when the file check or copy call is delayed. I have also tried setting the ReadFile to work asynchronously but that had no effect. I believe I am dealing with some low-level windows layer that no matter the language it exhibits a block on a shared resource -- and only when the application is executing under a single .NET process protected by Themida which evidently installs some hooks to allow .NET execution. At this time converting the entire application away from .NET is not an option. Nor is separating out the file copy logic to a separate task. I am wondering if anyone else has more knowledge of how a file operation can block another thread reading from a system port. I have included here example applications that show the problem: https://db.tt/cNMYfEIg - VB.NET https://db.tt/Y2lnTqw7 - MFC They are Visual Studio 2010 solutions. When running the themida protected exe, you can see when the FileThread counter pauses (executing the File.Exists call) while the ReadThread counter also pauses. When running non-protected visual studio output exe, the ReadThread counter does not pause which is how we expect it to function. Thanks!
