  • QUiLoader and ignored dynamic properties

    - by Googie
    I'm loading the .ui file, where one of the widgets (QComboBox) has a dynamic property (http://qt-project.org/doc/qt-5/properties.html#dynamic-properties). The UI file looks like this: <?xml version="1.0" encoding="UTF-8"?> <ui version="4.0"> <class>PopulateScriptConfig</class> <widget class="QWidget" name="PopulateScriptConfig"> <property name="geometry"> <rect> <x>0</x> <y>0</y> <width>400</width> <height>300</height> </rect> </property> <property name="windowTitle"> <string>Form</string> </property> <layout class="QVBoxLayout" name="verticalLayout"> <item> <widget class="QGroupBox" name="langGroup"> <property name="title"> <string>Language</string> </property> <layout class="QVBoxLayout" name="verticalLayout_3"> <item> <widget class="QComboBox" name="langCombo"> <property name="ScriptingLangCombo" stdset="0"> <bool>true</bool> </property> </widget> </item> </layout> </widget> </item> <item> <widget class="QGroupBox" name="codeGroup"> <property name="title"> <string>Implementation</string> </property> <layout class="QVBoxLayout" name="verticalLayout_2"> <item> <widget class="QPlainTextEdit" name="codeEdit"/> </item> </layout> </widget> </item> </layout> </widget> <resources/> <connections/> </ui> The important part is: <widget class="QComboBox" name="langCombo"> <property name="ScriptingLangCombo" stdset="0"> <bool>true</bool> </property> </widget> I'm loading the file with QUiLoader::load(). Note, that I have extended the QUiLoader class, but only to access createWidget() method, where I can query each widget like this: QWidget* UiLoader::createWidget(const QString& className, QWidget* parent, const QString& name) { QWidget* w = QUiLoader::createWidget(className, parent, name); qDebug() << w->dynamicPropertyNames(); return w; } As a result I see empty list displayed, so it seems like the dynamic property is completly ignored. Any ideas? P.S. I've made sure that I load correct file. 3 times.

  • How to use enumeration types in C++?

    - by Sagistic
    I do not understand how to use enumeration types. I understand what they are, but I don't quite get their purpose. I have made a program that inputs three sides of a triangle and outputs whether or not they are isosceles, scalene, or equilateral. I'm suppose to incorporate the enumeration type somewhere, but don't get where and how to use them. Any help would be appreciated. #include <iostream> using namespace std; enum triangleType {scalene, isosceles, equilateral, noTriangle}; void triangleShape(double x, double y, double z); int main() { double x, y, z; cout << "Please enter the three sides of a triangle:" << endl; cout << "Enter side 1: "; cin >> x; cout << endl; cout << "Enter side 2: "; cin >> y; cout << endl; cout << "Enter side 3: "; cin >> z; cout << endl; triangleShape(x, y, z); return 0; } void triangleShape(double x, double y, double z) { if (((x+y) > z) && ((x+z) > y) && ((y+z) > x)) { cout << "You have a triangle!" << endl; if (x == y && y == z) cout << "Your triangle is an equilateral" << endl; else if (x == y || x == z || y == z) cout << "Your triangle is an isosceles" << endl; else cout << "Your triangle is a scalene" << endl; } else if ((x+y) <= z || ((x+z) <= y) || ((y+z) <= x)) cout << "You do not have a triangle." << endl; }

  • Why LINQ to Entities won't let me initialize just some properties of an Entity?

    - by emzero
    So I've started to add Entity Framework 4 into a legacy web application (ASP.NET WebForms). As a start I have auto-generated some entities from the database. Also I want to apply Repository Pattern. There is an entity called Visitor and its repository VisitorRepository In VisitorRepository I have the following method: public IEnumerable<Visitor> GetActiveVisitors() { var visitors = from v in _context.Visitors where v.IsActive select new Visitor { VisitorID = v.VisitorID, EmailAddress = v.EmailAddress, RegisterDate = v.RegisterDate, Company = v.Company, Position = v.Position, FirstName = v.FirstName, LastName = v.LastName }; return visitors.ToList(); } That List is then bound to a repeater and when trying to do <%# Eval('EmailAddress') #%> it throws the following exception. The entity or complex type 'Model.Visitor' cannot be constructed in a LINQ to Entities query. A) Why is this happening? How I can workaround this? Do I need to select an anonymous type and then use that to initialize my entities??? B) Why every example I've seen makes use of 'select new' (anonymous object) instead of initializing a known type? Anonymous types are useless unless you are retrieving the data and showing it in the same layer. As far as I know anonymous types cannot be returned from methods? So what's the real point of them??? Thank you all

  • How to temporarily replace one primitive type with another when compiling to different targets in c#

    - by Keith
    How to easily/quickly replace float's for doubles (for example) for compiling to two different targets using these two particular choices of primitive types? Discussion: I have a large amount of c# code under development that I need to compile to alternatively use float, double or decimals depending on the use case of the target assembly. Using something like “class MYNumber : Double” so that it is only necessary to change one line of code does not work as Double is sealed, and obviously there is no #define in C#. Peppering the code with #if #else statements is also not an option, there is just too much supporting Math operators/related code using these particular primitive types. I am at a loss on how to do this apparently simple task, thanks! Edit: Just a quick comment in relation to boxing mentioned in Kyles reply: Unfortunately I need to avoid boxing, mainly since float's are being chosen when maximum speed is required, and decimals when maximum accuracy is the priority (and taking the 20x+ performance hit is acceptable). Boxing would probably rules out decimals as a valid choice and defeat the purpose somewhat. Edit2: For reference, those suggesting generics as a possible answer to this question note that there are many issues which count generics out (at least for our needs). For an overview and further references see Using generics for calculations

  • Varchar columns: Nullable or not.

    - by NYSystemsAnalyst
    The database development standards in our organization state the varchar fields should not allow null values. They should have a default value of an empty string (""). I know this makes querying and concatenation easier, but today, one of my coworkers questioned me about why that standard only existed for varchar types an not other datatypes (int, datetime, etc). I would like to know if others consider this to be a valid, defensible standard, or if varchar should be treated the same as fields of other data types? I believe this standard is valid for the following reason: I believe that an empty string and null values, though technically different, are conceptually the same. An empty, zero length string is a string that does not exist. It has no value. However, a numeric value of 0 is not the same as NULL. For example, if a field called OutstandingBalance has a value of 0, it means there are $0.00 remaining. However, if the same field is NULL, that means the value is unknown. On the other hand, a field called CustomerName with a value of "" is basically the same as a value of NULL because both represent the non-existence of the name. I read somewhere that an analogy for an empty string vs. NULL is that of a blank CD vs. no CD. However, I believe this to be a false analogy because a blank CD still phyically exists and still has physical data space that does not have any meaningful data written to it. Basically, I believe a blank CD is the equivalent of a string of blank spaces (" "), not an empty string. Therefore, I believe a string of blank spaces to be an actual value separate from NULL, but an empty string to be the absense of value conceptually equivalent to NULL. Please let me know if my beliefs regarding variable length strings are valid, or please enlighten me if they are not. I have read several blogs / arguments regarding this subject, but still do not see a true conceptual difference between NULLs and empty strings.

  • Recovery of Pinnacle Studio Project Files

    - by seanieb
    My external hard drive had some sort of issue a few months ago, but I was able to recover my files using a data recovery software program. However my Pinnacle studio files are not being recovered as before, they are being recovered as directory's/folders that have sub directory's and files. And I have tried with several different recovery programs and they all recover the projects as directories. And the projects all contain one file called README.TXT: * WARNING This directory contains the descriptive data of the project, split into. various subdirectories and files for better access. DO NOT EDIT, ADD, CHANGE OR MODIFY ANY OF IT'S CONTENTS! This gives me hope that I could some how just turn the directory into a .stu Pinnacle studio project file. How would I go about doing this? Or is there another way to solve this problem?

  • mime-attachment incompatibility on forwarded messages from android to an iphone

    - by Peter Carrero
    A couple of guys got the evo android in the office. I got an iphone. When I receive a forwarded email from one of those phones, the forwarded piece comes as a mime-attachment that the iphone cannot open. I also tried this with a motorola droid and got the same result. I am not sure if the issue is the android sending the message on the wrong format or the iphone not being able to understand a mime type that it should... Has anyone experienced this, and, most importantly, found a fix/workaround? Thanks.

  • Pictures clicked on Start Menu's Recent Items list opens in non default program

    - by jay
    I am using Picasa Photo Viewer and have associated all JPG and PNG files to open with it. However when I open an image from the Recent Items list in the Windows 7 Start Menu it opens with Windows Photo Viewer. The context menu for such items reveals no actions that would make it go to Windows Photo Viewer, and the default (one in bold) opens with the Picasa viewer as you'd expect. It's just that the left click behaves differently for some reason. Any ideas on how to fix this?

  • Is this a File Header / Magic Number?

    - by Hammer Bro.
    I've got 120,000 files (way more, actually; this is just an arbitrary subset) of an unknown type. Linux file does not identify them (not that they're necessarily Linux files), nor do any other methods I've tried. There are only two hints about them that I currently have. One is that I suspect some compression is employed -- I have metadata that claims the file sizes are always some amount larger than what I observe. The other is that in 100,000 of these files, the first 16 bytes are always: ff ee ee dd 00 00 00 00 01 00 00 00 00 00 00 00 That really looks like a file header/magic number to me, but I just can't place it. Does anyone know what kind of files this would indicate? Alternatively, can anyone convince me that these suspiciously common bytes certainly do not indicate a specific file type? UPDATE I don't know the exact reverse-engineering details, but most of the files in our case are zips after the first 29(? or so) bytes are ignored. So in practice the problem is solved (we know how to process the files) but in theory the question is still unanswered -- I don't know which application routinely prepends about 29 bytes to its zips. [I'm not sure if I should leave the question open or not at this point.]

  • Adding file type to ack permanently

    - by Martin Tóth
    I've recently learned how to let ack support more filetypes (adding the following to .ackrc): --type-add latte=.latte Unfortunately, that produces an info line on every ack search I use, even ones with 0 results. $ ack --latte dump ack: --type-add: Type "latte" does not exist, creating with ".latte" ... Is there a way to make this a more permanent addition? (i.e. get rid of this info line) This looks to me like it's adding this new type on every ack call. Is it a problem with my installation of ack? I'm on Mac OS X 10.5.8 with ack 1.92 (Running under Perl 5.10.1)

  • Utility for extracting MIME attachments

    - by tripleee
    I am looking for a command-line tool for Unix (ideally, available in a Debian / Ubuntu package) for extracting all MIME parts from a multipart email message (or the body from a singlepart with an interesting content-type, for that matter). I have been using the mimeexplode tool which ships with the Perl MIME::Tools package, but it's not really production quality (the script is included as an example only, and has issues with what it regards as "evil" character sets) and I could certainly roll my own script based on that, but if this particular wheel has already been innovated, perhaps I shouldn't.

  • How to change defaulp pdf viewer for all users in command line

    - by dodecaplex
    I'm using Debian squeeze with Gnome Desktop for all my users. I have a group of machines to set up so that all users should use xpdf as a default viewer (rather than evince). I want this set up to be done by command line (even better, using puppet). I know about xpg-mime command, but the man page says that the default command should not be used as root. I could manually tweek the /etc/gnome/defaults.list files, but I'm looking for a single command I could run to perform the setting without an editor interaction. Any idea ?

  • using xml type attribute for derived complex types

    - by David Michel
    Hi All, I'm trying to get derived complex types from a base type in an xsd schema. it works well when I do this (inspired by this): xml file: <person xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="Employee"> <name>John</name> <height>59</height> <jobDescription>manager</jobDescription> </person> xsd file: <xs:element name="person" type="Person"/> <xs:complexType name="Person" abstract="true"> <xs:sequence> <xs:element name= "name" type="xs:string"/> <xs:element name= "height" type="xs:double" /> </xs:sequence> </xs:complexType> <xs:complexType name="Employee"> <xs:complexContent> <xs:extension base="Person"> <xs:sequence> <xs:element name="jobDescription" type="xs:string" /> </xs:sequence> </xs:extension> </xs:complexContent> </xs:complexType> However, if I want to have the person element inside, for example, a sequence of another complex type, it doesn't work anymore: xml: <staffRecord> <company>mycompany</company> <dpt>sales</dpt> <person xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="Employee"> <name>John</name> <height>59</height> <jobDescription>manager</jobDescription> </person> </staffRecord> xsd file: <xs:element name="staffRecord"> <xs:complexType> <xs:sequence> <xs:element name="company" type="xs:string"/> <xs:element name="dpt" type="xs:string"/> <xs:element name="person" type="Person"/> <xs:complexType name="Person" abstract="true"> <xs:sequence> <xs:element name= "name" type="xs:string"/> <xs:element name= "height" type="xs:double" /> </xs:sequence> </xs:complexType> <xs:complexType name="Employee"> <xs:complexContent> <xs:extension base="Person"> <xs:sequence> <xs:element name="jobDescription" type="xs:string" /> </xs:sequence> </xs:extension> </xs:complexContent> </xs:complexType> </xs:sequence> </xs:complexType> </xs:element> When validating the xml with that schema with xmllint (under linux), I get this error message then: config.xsd:12: element complexType: Schemas parser error : Element '{http://www.w3.org/2001/XMLSchema}sequence': The content is not valid.

  • SQL Injection Protection for dynamic queries

    - by jbugeja
    The typical controls against SQL injection flaws are to use bind variables (cfqueryparam tag), validation of string data and to turn to stored procedures for the actual SQL layer. This is all fine and I agree, however what if the site is a legacy one and it features a lot of dynamic queries. Then, rewriting all the queries is a herculean task and it requires an extensive period of regression and performance testing. I was thinking of using a dynamic SQL filter and calling it prior to calling cfquery for the actual execution. I found one filter in CFLib.org (http://www.cflib.org/udf/sqlSafe): <cfscript> /** * Cleans string of potential sql injection. * * @param string String to modify. (Required) * @return Returns a string. * @author Bryan Murphy ([email protected]) * @version 1, May 26, 2005 */ function metaguardSQLSafe(string) { var sqlList = "-- ,'"; var replacementList = "#chr(38)##chr(35)##chr(52)##chr(53)##chr(59)##chr(38)##chr(35)##chr(52)##chr(53)##chr(59)# , #chr(38)##chr(35)##chr(51)##chr(57)##chr(59)#"; return trim(replaceList( string , sqlList , replacementList )); } </cfscript> This seems to be quite a simple filter and I would like to know if there are ways to improve it or to come up with a better solution?

  • Wordpress dynamic navigation function for highlighting single post tabs

    - by user269959
    I am trying to write a function that i can reuse in my wordpress themes that will allow me to build robust dynamic navigation menus. Here is what i have so far: function tab_maker($page_name, $href, $tabname) { //opens <li> tag to allow active class to be inserted if tab is on proper page echo "<li"; //checks that we are on current page and highlights tab as active if so if(is_page($page_name)){ echo " class='current_page_item'>"; } //closes <li> tab if not active else { echo ">"; } //inserts the link as $href and the name of the tab to appear as $tabname then closes <li> echo "<a href=$href>$tabname</a>"; echo "</li>"; } This code works as expected except i cant enable it to highlight for a single blog post as the page names are dynamic. I know about the wordpress function is_single() which ive used to implement this feature in previous nav menus but i cant find a way to integrate it into this function. appreciate any help!

  • popup with dynamic menuitems, each menuitem is another popup

    - by encryptor
    I am building an extension that has a pop up whose elements are constructed by a function call everytime the mouse hovers over the popup option. I am able to achieve this. Now I need to have a popup for each of the menu item (inside the original popup) which is not dynamic though. I have this code, but it does not work: for (var m=0; m < localpubliclist.length; m++) { var newItem = document.createElement("menu"); newItem.setAttribute("label", publicdisplayname[m]); newItem.setAttribute("id", "public" + m); myMenuPopup.appendChild(newItem); var newpopup = document.createElement("menupopup"); newpopup.setAttribute("id","publicpop" + m); newItem.appendChild(newpopup); var new1= document.createElement("menuitem"); new1.setAttribute("label", "Home"); new1.setAttribute("id", "publichome" + m); newpopup.appendChild(new1); } doing this forms the first popup where i can see all my menu with names publicdisplayname[m]. each of these is to be a popup which displays "Home". This does not work. the second popup (popup on publicdisplayname[m]) does not open. i have been stuck on this for quite some time and have tried various things cut it doesnt work. Can we do this at all? can we have double dynamic popups?

  • Change dynamic web reference from web./app.config

    - by Snæbjørn
    I have a problem changing a dynamic web reference in the config file. Changing the url in the config file doesn't have any effect. I have to change the url in .settings and compile for it to change. I added the web reference using the wizard. Set the URL behavior to dynamic, which added the relevant XML tags in config file. In my solution I have the web API (web reference) in a separate project (class lib), so I referenced the project and copied the <applicationSettings> over. <applicationSettings> <StartupProject.Properties.Settings> <setting name="WebReference" serializeAs="String"> <value>http://someurl/somefile.asmx</value> </setting> </StartupProject.Properties.Settings> </applicationSettings> Note that it's <StartupProject.Properties.Settings> and not <WebRefProject.Properties.Settings>. Are there some limitations I'm not aware of or am I doing something wrong?

  • Difference dynamic static 2d array c++

    - by snorlaks
    Hello, Im using opensource library called wxFreeChart to draw some XY charts. In example there is code which uses static array as a serie : double data1[][2] = { { 10, 20, }, { 13, 16, }, { 7, 30, }, { 15, 34, }, { 25, 4, }, }; dataset->AddSerie((double *) data1, WXSIZEOF(dynamicArray)); WXSIZEOF ismacro defined like: sizeof(array)/sizeof(array[0]) In this case everything works great but in my program Im using dynamic arrays (according to users input). I made a test and wrotecode like below: double **dynamicArray = NULL; dynamicArray = new double *[5] ; for( int i = 0 ; i < 5 ; i++ ) dynamicArray[i] = new double[2]; dynamicArray [0][0] = 10; dynamicArray [0][1] = 20; dynamicArray [1][0] = 13; dynamicArray [1][1] = 16; dynamicArray [2][0] = 7; dynamicArray [2][1] = 30; dynamicArray [3][0] = 15; dynamicArray [3][1] = 34; dynamicArray [4][0] = 25; dynamicArray [4][1] = 4; dataset->AddSerie((double *) *dynamicArray, WXSIZEOF(dynamicArray)); But it doesnt work correctly. I mean point arent drawn. I wonder if there is any possibility that I can "cheat" that method and give it dynamic array in way it understands it and will read data from correct place thanks for help

  • Dynamic Linq Library Guid exceptions

    - by Adan
    I am having a problem with the Dynamic Linq Library. I get a the following error "ParserException was unhandled by user code ')" or ','". I have a Dicitionary and I want to create a query based on this dictionary. So I loop through my dictionary and append to a string builder "PersonId = (GUID FROM DICTIONARY). I think the problem is were I append to PersonId for some reason I can't seem to convert my string guid to a Guid so the dynamic library don't crash. I have tried this to convert my string guid to a guid, but no luck. query.Append("(PersonId = Guid(" + person.Key + ")"); query.Append("(PersonId = " + person.Key + ")"); I am using VS 2010 RTM and RIA Services as well as the Entity Framework 4. //This is the loop I use foreach (KeyValuePair<Guid, PersonDetails> person in personsDetails) { if ((person.Value as PersonDetails).IsExchangeChecked) { query.Append("(PersonId = Guid.Parse(" + person.Key + ")"); } } //Domain service call var query = this.ObjectContext.Persons.Where(DynamicExpression.ParseLambda<Person, bool>(persons)); Please help, and if you know of a better way of doing this I am open to suggestions.

  • Running an existing LINQ query against a dynamic object (DataTable like)

    - by TomTom
    Hello, I am working on a generic OData provider to go against a custom data provider that we have here. Thsi is fully dynamic in that I query the data provider for the table it knows. I have a basic storage structure in place so far based on the OData sample code. My problem is: OData supports queries and expects me to hand in an IQueryable implementation. On the lowe rside, I dont have any query support. Not a joke - the provider returns tables and the WHERE clause is not supported. Performance is not an issue here - the tables are small. It is ok to sort them in the OData provider. My main problem is this. I submit a SQL statement to get out the data of a table. The result is some sort of ADO.NET data reader here. I need to expose an IQueryable implementation for this data to potentially allow later filtering. Any ide ahow to best touch that? .NET 3.5 only (no 4.0 planned for some time). I was seriously thinking of creating dynamic DTO classes for every table (emitting bytecode) so I can use standard LINQ. Right now I am using a dictionary per entry (not too efficient) but I see no real way to filter / sort based on them.
