  • Why is the dictionary debug visualizer less useful in Visual Studio 2010 for Silverlight debugging?

    - by Kevin
    I was debugging in Visual Studio 2010, which we just installed and trying to look at a dictionary in the quick watch window. I see Keys and Values, but drilling into those shows the Count and Non-Public members, Non-Public members continues the trail and I never see the values in the dictionary. I can run test.Take(10) and see the values, but why should I have to do that. I don't have VS 2008 installed anymore to compare, but it seems that I could debug a dictionary much easier. Why is it this way now? Is it just a setting I set somehow on my machine? Test code: Dictionary<string, string> test = new Dictionary<string, string>(); test.Add("a", "b"); EDIT: I've just tried the same debug in a Console app and it works as expected. The other project is a Silverlight 4 application, why are they different? Console Debug Screen Shot Silverlight 4 Debug Screen Shot:

  • Embedding Python in C: Having problems importin local modules

    - by Drew
    I'm needing to run Python scripts within a C-based app. I am able to import standard modules from the Python libraries i.e.: PyRun_SimpleString("import sys") But when I try to import a local module 'can' PyRun_SimpleString("import can") returns the error msg: Traceback (most recent call last): File "", line 1, in ImportError: No module named can When I type the command "import can" in iPython, the system is able to find it. How can I link my app with can? I've tried setting PYTHONPATH to my working directory. Thanks.

  • TextField Caret Does Not Display in Actionscript 3

    - by Cinegod
    Hello all, I am trying to display a text field that has text inside it, and display the flashing Caret at the end of the text. I have tried the following: Code: // ti_title is my textField stage.focus = ti_title; ti_title.setSelection( ti_title.length, ti_title.length ); I have also tried: // ti_title is my textField ti_title.stage.focus = ti_title; ti_title.setSelection( ti_title.length, ti_title.length ); The field is focused because I can type into it, but I do not see a Caret until I have started typing. This is not very good for usability. I have even tried removing text then re-adding it and then setting the selection again, but still not working. Any ideas? all the best nG

  • Problem with input filter using doxygen 1.6.3 on windows XP

    - by Marc
    I am trying to use doxygen to generate documentation for some matlab classes I have written. I am using the doxygen-matlab package, which includes a perl script to kludge matlab .m files into c++ style commented files, so that doxygen can read them. In my doxyfile, I have set (according to the instructions) FILTER_PATTERNS = *m=C:/doxygenMatlab/m2cpp.pl However, when the code runs, rather than running the script on the input files, it appears to just open the script using whatever the default windows setting for .pl is. IE, if I associate .pl with notepad, the script is opened by notepad once for each input file doxygen is trying to parse. If I associate .pl with perl.exe, the script runs and throws the no argument error Argument must contain filename -1 at C:\doxygenMatlab\m2cpp.pl line 4. The doxygen documentation says Doxygen will invoke the filter program by executing (via popen()) the command <filter> <input-file> So I am wondering if there is some problem with popen() and windows that I could fix.

  • How to change the default Help browser for VS2010?

    - by Scott Bilas
    Visual Studio 2010 changed the help system to run a little daemon and launch the system default web browser to view it. I'm using Firefox for my system browser but would like to use Chrome for VS help. Is there an option to change the Help browser that I'm not seeing in Tools|Options? If not, is there a workaround or registry setting to do this? As a backup I've been using H3Viewer but I'd like to be able to get context-sensitive F1 help from within the VS IDE.

  • User control attributes at design-time

    - by ciscoheat
    I'm testing a simple User Control in Visual Studio 2008: A Panel named Wrapper with some controls inside. Can Visual Studio handle this at design time? public partial class TestControl : System.Web.UI.UserControl { [Description("Css class of the div around the control.")] [CssClassProperty] public string CssClass { get { return Wrapper.CssClass; } set { Wrapper.CssClass = value; } } } When setting the CssClass property, it doesn't update the css of the Panel at design time. Am I hoping for too much?

  • Qt: Dragging a widget to scroll the widget's parent QScrollArea?

    - by samsonite
    I've got a long horizontal QLabel displaying a png (the image shows a signal/time graph). Under that, I've got a QTableWidget. Both of these are in a QScrollArea because I want them to stay vertically aligned (the cells in the table correspond with the signal seen directly above them). I'm trying to add a handler to the QLabel such that the user can use the picture itself to scroll the scrollarea, rather than having to use the scrollbar. Is there a tried-and-tested way to do this? Directly setting the scrollarea's sliderPosition inside the QLabel's dragMoveEvent doesn't seem smart, because when the scrollarea scrolls it also leads to another dragMoveEvent on the (moving) QLabel.

  • API For Flex Apps To Interact

    - by dimo414
    I have a large flex application (the app) running on one server, and many small flex applications (widgets) running on another server, which are to be included in the app so that visually the user see's one continuous application. Due to proprietary third party software, this structure cannot be changed. I am looking for some way to allow the app and the widgets to communicate, allowing the app to make changes to the widgets and the the widgets to notify the app when events are triggered, so that user interaction is fluid and continuous. There are a few related questions which indicate it's possible to do this by setting up event triggers and listeners. I am wondering if there is any standardized way to do this (the answers aren't very clear) or if anyone has developed a library or API to make this easier.

  • VS 2010 / Resharper 5 Mouse Behavior

    - by Berryl
    After upgrading to the above configuration I notice that 1) CTRL-Click on a type highlights the type but doesn't take me to the declaration, 2) Clicking on some closure (ie, like a method) toggles whether it's expanded or collapsed. Since these are both mouse related tasks I figure there is some setting in either VS or R# that I need to change, but I sure can't figure out what it is. Anybody know? Cheers, Berryl PS - there is an option in R# to ctrl-click to the type but I have that checked and it still does not work.

  • Java application failing on special characters.

    - by Scottm
    An application I am working on reads information from files to populate a database. Some of the characters in the files are non-English, for example accented French characters. The application is working fine in Windows but on our Solaris machine it is failing to recognise the special characters and is throwing an exception. For example when it encounters the accented e in "Gérer" it says :- Encountered: "\u0161" (353), after : "\'G\u00c3\u00a9rer les mod\u00c3" (an exception which is thrown from our application) I suspect that in order to stop this from happening I need to change the file.encoding property of the JVM. I tried to do this via System.setProperty() but it has not stopped the error from occurring. Are there any suggestions for what I could do? I was thinking about setting the basic locale of the solaris platform in /etc/default/init to be UTF-8. Does anyone think this might help? Any thoughts are much appreciated.

  • Using the C Cluster library in Visual C++.

    - by Stefan K.
    Right so i'm trying to use a C library in C++, never actually done this before i thought it would be a case of declaring the header includes under a extern "C" and setting the compile as flag to "default" but i'm still getting linker errors and think that the header file might have to be complied as a DLL. I have no idea really. Is it the library that's the problem or is it me? There are some make files in the cluster-1.47\src, but i don't know how or if they relate to "cluster.h". I've uploaded a visual studio 2008 project for anyone to take a gander, any help would be appreciated as i've been hitting my head against the wall for time now. thanks Stefan Link to Visual Studio 2008 Project

  • why do i lose my hidden field value?

    - by user517406
    Hi, I have some hidden fields on my page, all of which work fine apart from one. I am setting the value in document.ready, before calling buildGrid() : $(document).ready(function() { $.ajax( { type: "POST", url: "/CDServices.asmx/GetWeekEndingDates", data: "{}", dataType: "json", contentType: "application/json; charset=utf-8", success: function(msg) { //store default dates in hidden fields $("#<%=hdnCurrentDate.ClientID%>").val(msg.d.CurrentDate); $("#<%=hdnLastWeekEndingDate.ClientID%>").val(msg.d.LastWeekEndingDate); } }); buildGrid(); }); Yet in buildGrid, the value in the hidden field is empty : function buildGrid() { alert($("#<%=hdnLastWeekEndingDate.ClientID%>").val()); I call other functions on button clicks where the hidden field value is picked up fine, why does the value disappear here?

  • get entire line with java.util.scanner.hasNext(regex)

    - by Hussain
    I'm doing something in Java that requires input to be matched against the pattern ^[1-5]$. I should have a while loop looping through each line of input, checking it against the pattern, and outputting an error message if it does not. Sudo code: while (regex_match(/^[^1-5]$/,inputLine)) { print ("Please enter a number between 1 and 5! "); getNextInputLine(); } I can use java.util.Scanner.hasMatch("^[^1-5]$"), but that will only match a single token, not the entire line. Any idea on how to make hasMatch match against the entire line? (Setting the delimiter to "\n" or "\0" doesn't work.)

  • How do I change the JAVA_HOME for ant?

    - by Eugene M
    I'm doing java work on a class server where I don't have root. Whenever I try to compile using ant, it points to the wrong directory (/usr/tomcat instead of /usr/tomcat/jre ). One of the things we were told to do when setting up our user accounts was to add export JAVA_HOME=/usr/tomcat/jre to the .bashrc file. I don't know if that was supposed to take care of the problem but it doesn't seem to. So, how can I change the JAVA_HOME property for ant but only for when I run ant? EDIT: echo $JAVA_HOME points to /usr/tomcat/jre echo $JAVA_HOME\bin points to /usr/tomcat/jrebin The problem is when I normally run ant I get this error: Unable to locate tools.jar. Expected to find it in /usr/tomcat/lib/tools.jar Buildfile: build.xml compile: [javac] Compiling 1 source file to /home/ejm244/build/classes BUILD FAILED /home/ejm244/build.xml:9: Unable to find a javac compiler; com.sun.tools.javac.Main is not on the classpath.

  • Bullet physics engine, how to freeze an object?

    - by Markus
    Using Bullet 2.76 I'm trying to freeze an object (rigid body) so that it instantly stops moving, but still responds to collisions. I tried setting it's activation state to DISABLE_SIMULATION, but then it's virtually nonexistent to other objects. Furthermore, if objects "collide" with it when it's disabled, strange things begin to happen (object's falling through static bodies, etc.) I suppose, temporarily converting it to a static rigid body could work, but is there an existing "native" way to achieve this on Bullet's side? Edit: Is there a way to turn off gravity for a specific object?

  • Have visual studio copy x64 DLL or x86 DLL when building a C# project

    - by MrPurpleStreak
    We're building a C# app that uses an external DLL for Sqlite.NET. This is a .NET dll but it embeds a C dll inside it and so it comes in x86 and x64 flavours. We add a reference to the x86 version in the project so when we build and run on x86 it's fine. Visual studio copies the dll to the bin folder and runs. On x64 it still copies the x86 version of course and then when it runs it fails to load it. We get round this by temporarily setting our project to be x86 only, but ideally we'd like to tell visual studio to copy the correct version depending on which flavour of machine it is. Any ideas how?

  • SSL_CTX_set_cert_verify_callback vs. SSL_CTX_set_verify

    - by BreakPoint
    Hello, Can anyone tell me what is the difference between SSL_CTX_set_cert_verify_callback and SSL_CTX_set_verify? From OpenSSL docs: SSL_CTX_set_cert_verify_callback() sets the verification callback function for ctx. SSL objects that are created from ctx inherit the setting valid at the time when SSL_new(3) is called. and: SSL_CTX_set_verify() sets the verification flags for ctx to be mode and specifies the verify_callback function to be used. If no callback function shall be specified, the NULL pointer can be used for verify_callback. So I'm trying to understand which callback to send for each one (from client side). Thanks experts.

  • Can StructureMap be configured so that one can use different .config settings based on whether the p

    - by Mark Rogers
    I know that in StructureMap I can read from my *.config files (or files referenced by them), when I want to pass specific arguments to an object's constructor. ForRequestedType<IConfiguration>() .TheDefault.Is.OfConcreteType<SqlServerConfiguration>() .WithCtorArg("db_server_address") .EqualToAppSetting("data.db_server_address") But what I would like to do is read from one config setting in debug mode and another in release mode. Sure I could surround the .EqualToAppSetting("data.db_server_address"), with #if DEBUG, but for some reason those statements make me cringe a little when I put them in. I'd like to know if there was some way to do this with the StructureMap library itself. So can I feed my objects different settings based on whether the project is built in debug or release mode?

  • NetNamedPipe: varying response time when communication is idling

    - by Sven Künzler
    I have two WCF apps communicating one-way over named pipes. All is nice, except for one thing: Normally, the request/response cycle takes zero (marginal) time. However, if there was a time span of, say, half a minute without any communication, the request/response increases up to ~300-500ms. I looked around the net and I got the idea of using a heart beat/ping mechanism to keep the communication channel busy. Using trial and error I found that when doing a request each 10 seconds, the response times stay low. Starting at around 15s intervals, the "hiccup" response times begin to appear. Now I'm wondering where this phenomenon is originating from. I tried setting alle conceivable timeouts on both sides to 1 minute, but that did not help. Can anybody explain what's going on there?

  • jquery/javascript: accessing contents of an iframe

    - by rz
    I would like to manipulate the html inside an iframe using jquery. I thought I'd be able to do this by setting the context of the jQuery function to be the document of the iframe, something like: $(function(){//document ready $('some selector', frames['nameOfMyIframe'].document).doStuff() }); However this doesn't seem to work. A bit of inspection shows me that the variables in frames['nameOfMyIframe'] are undefined unless I wait a while for the iframe to load. However, when the iframe loads the variables are unaccessible (I get permission denied type errors). Does anyone know of way to work around this?

  • Side effects of reordering columns in PostgreSQL

    - by Summer
    I sometimes re-order the columns in my Postgres DB. Since Postgres can only add columns at the end of tables, I end up re-ordering by adding new columns at the end of the table, setting them equal to existing columns, and then dropping the original columns. My question is: what does PostgreSQL do with the memory that's freed by dropped columns? Does it automatically re-use the memory, so a single record consumes the same amount of space as it did beforehand? But that would require a re-write of the whole table, so to avoid that, does it just keep a bunch of blank space around in each record? Thanks! ~S

  • C# Inherited member variables behaving undexpectedly

    - by Nilbert
    If I have a class like this: class A { public string fe = "A"; } And a class that inherits from it like so: class B : A { public string fe = "B"; } Visual C++ will tell me that B.fe hides A.fe so I should use the new keyword. So I change class B to look like: class B : A { public new string fe = "B"; } And then I have a function that takes an A (but, by virtue of inheritance, will also take a B) like this: class D { public static void blah(A anAObject) { Console.Writeline(A.fe); } } Even when I pass it an instance of a B object, which it will take without question, it will print "A"! Why is this, and how can I make it work how I want without setting the variable in the constructor?

  • Binding Properties.Settings to Textbox fails

    - by user268098
    I would like to define a key & value in Settings.settings and bind the value by declaration in the XAML (not in the code behind by command). Here's what I've been trying in vain: Create a WPF project "Exp1" with Visual Studio Express 2010. Set one key named "TextFromSettings" to the value "Some Text from Setting". Add the attribute xmlns:p="clr-namespace:Exp1.Properties;assembly=Exp1" to the tag. Add Text="{Binding Path=TextFromSettings, Mode=TwoWay, Source={x:Static p:Settings.Default}}" to the tag Now, the preview window shows the text, however, the compiler fails: "Error 1 Cannot find the type 'Settings'. Note that type names are case sensitive." Where am I going wrong?
