  • Binding DataTemplates (or another aproach)

    - by Bataglião
    Hi all, I'm having some troubles trying to dynamically generate content in WPF and after it bind data. I have the following scenario: TabControl - Dynamically generated TabItems through DataTemplate - inside TabItems, I have dynamic content generated by DataTemplate that I wish to bind (ListBox). The code follows: ::TabControl <TabControl Height="252" HorizontalAlignment="Left" Name="tabControl1" VerticalAlignment="Top" Width="458" Margin="12,12,12,12" ContentTemplate="{StaticResource tabItemContent}"></TabControl> ::The Template for TabControl to generate TabItems <DataTemplate x:Key="tabItemContent"> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="*" /> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition Height="*" /> </Grid.RowDefinitions> <ListBox ItemTemplate="{StaticResource listBoxContent}" ItemsSource="{Binding}"> </ListBox> </Grid> </DataTemplate> ::The template for ListBox Inside each TabItem <DataTemplate x:Key="listBoxContent"> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="22"/> <ColumnDefinition Width="*" /> </Grid.ColumnDefinitions> <Image Grid.Column="0" Source="{Binding Path=PluginIcon}" /> <TextBlock Grid.Column="1" Text="{Binding Path=Text}" /> </Grid> </DataTemplate> So, when I try to do this on code inside a loop to create the tabitems: TabItem tabitem = tabControl1.Items[catIndex] as TabItem; tabitem.DataContext = plugins.ToList(); where 'plugins' is an Enumerable The ListBox is not bounded. I tried also to find the ListBox inside the TabItem to set the ItemSource property but no success at all. Someone have an idea on how to do that? Thanks in advance.

  • C++ Returning a Reference

    - by Devil Jin
    Consider the following code where I am returning double& and a string&. The thing works fine in the case of a double but not in the case of a string. Why is this difference in the behavior? In both the cases compiler does not even throws the Warning: returning address of local variable or temporary as I am returning a reference. #include <iostream> #include <string> using namespace std; double &getDouble(){ double h = 46.5; double &hours = h; return hours; } string &getString(){ string str = "Devil Jin"; string &refStr = str; return refStr; } int main(){ double d = getDouble(); cout << "Double = " << d << endl; string str = getString(); cout << "String = " << str.c_str() << endl; return 0; } Output: $ ./a.exe Double = 46.5 String =

  • How to run unittest for Django?

    - by photon
    I configured properties for my django project under pydev. I can run the django app under pydev or under console window. But I have problems to run unittest under pydev. I cannot run unittest for app under console window either. I guessed it's something related to run configurations of pydev, so I made several trials, but with no success. Once I got messages like this: ImportError: Could not import settings 'D:\django_projects\MyProject' (Is it on sys.path? Does it have syntax errors?): No module named D:\django_projects\MyProject ERROR: Module: MyUnittestFile could not be imported. Another time I got messages like this: ImportError: Could not import settings 'MyProject.settngs' (Is it on sys.path? Does it have syntax errors?): No module named settngs 'ERROR: Module: MyUnittestFile could not be imported. I use pydev 1.5.6 on eclipse and windows xp. Any ideas for this problem? Now I think it's not something related to pydev, thanks for Xavier Ho's suggestion.

  • How to get a number closest to the average in c++?

    - by Alex Zielinski
    What I'm trying to achieve is to take the average of the numbers stored in the array and find the number which is closest to it. My code compiles, but has an error just after starting. I think it's something to do with the memory handling (I don't feel confident with pointers, etc. yet) Could some nice guy take a look at my code and tell me what's wrong with it? (don't be hard on me, I'm a beginner) #include <iostream> #include <cmath> using namespace std; double* aver(double* arr, size_t size, double& average); int main() { double arr[] = {1,2,3,4,5,7}; size_t size = sizeof(arr)/sizeof(arr[0]); double average = 0; double* p = aver(arr,size,average); cout << *p << " " << average << endl; } double* aver(double* arr, size_t size, double& average){ int i,j,sum; double* m = 0; int tmp[7]; for(i=0;i<size;i++) sum += arr[i]; average = sum/size; for(j=0;j<size;j++){ tmp[j] = arr[j] - average; if(abs(tmp[j])>*m) *m = tmp[j]; } return m; }

  • Conditional "Get Script File" in Javascript without using a library function

    - by Adam
    I work at a company that has many clients that have their own website that "plugs in" to our system. In other words they have their own website and they have a link that, when the user clicks it, transitions them over to our site. There is a feature that I want to track by giving the client a small block of code to put on their homepage. Whenever the homepage is loaded with a certain query string variable I want the block of code to request a file on my server. Then on the server I'll record the tracking info based on the query string. All this would be really easy if I can guarantee that the client would be using jQuery or some similar library, but there are a lot of clients and I can't really rely on them all using jQuery. At the same time I'd like to limit the size of the block of javascript code that they paste in. I think the best solution would be to have something like: if(querystring.substring("Tracking=") > 0) { include("blah.aspx?TrackingQS=" + querystring); } but I can't find a include function in built-in javascript without calling some library like jQuery. Any thoughts?? I could do straight up AJAX but I want to limit the number of lines of code for several reasons that I won't bore you with here.

  • How to run White + SL4 UATs through TeamCity?

    - by Duncan Bayne
    After experiencing a series of unpleasant issues with TFS, including source code orruption and project management inflexibility, we (meaning the project team of which I'm a part) have decided to move from TFS 2010 to TeamCity + SVN + V1. I've managed to get our MSTest component and unit tests running as part of every build. However, our UATs are failing, and I was hoping for some advice from the TeamCity community as to best practices w.r.t. running web servers and interacting with the desktop. Each of our UAT fixtures starts a web server to host the site, like this: public static void StartWebServer() { var pathToSite = @"C:\projects\myproject\FrontEnd\MyProject.FrontEnd.Web"; var webServer = new Process { StartInfo = new ProcessStartInfo { Arguments = string.Format("/port:9150 /path:\"{0}\"", pathToSite), FileName = @"C:\Program Files (x86)\Common Files\microsoft shared\DevServer\10.0\WebDev.WebServer40.EXE" } }; webServer.Start(); } Needless to say, this doesn't work when running through TeamCity, as the pathToSite value is different each time. I'm hoping there is a way of determining the path into which the the code is checked out prior to building? That would allow me to point the web server at the right place. The other issue is that our UATs use White to drive the Silverlight UI through an instance of Internet Explorer: _browserWindow = InternetExplorer.Launch("http://localhost:9150/index.html#/Home", "Home - Windows Internet Explorer"); _document = _browserWindow.SilverlightDocument; I've ensured that the TeamCity service is granted the ability to interact with the desktop, and I've set the build agent machine up to log in automatically (an open session is a pre-requisite for White to work properly). Is that all I need to do or are there additional steps required?

  • Setting spring bean property value using ref-bean

    - by Apache Fan
    Hi, I am trying to set a property value using spring. <bean id="velocityPropsBean" class="com.test.CustomProperties" abstract="false" singleton="true" lazy-init="false" autowire="default" dependency-check="default"> <property name="properties"> <props> <prop key="resource.loader">file</prop> <prop key="file.resource.loader.cache">true</prop> <prop key="file.resource.loader.class">org.apache.velocity.runtime.resource.loader.FileResourceLoader</prop> <prop key="file.resource.loader.path">NEED TO INSERT VALUE AT STARTUP</prop> </props> </property> </bean> <bean id="velocityResourcePath" class="java.lang.String" factory-bean="velocityHelper" factory-method="getLoaderPath"/> Now what i need to do is insert the result from getLoaderPath into file.resource.loader.path. The value of getLoaderPath changes so it has to be loaded at server startup. Any thoughts how i can inset the velocityResourcePath value to the property?

  • JPA2 Criteria API creates invalid SQL when using groupBy

    - by Stephan
    JPA2 with the Criteria API seems to generate invalid SQL for PostgreSQL. For this code: Root<DBObjectAccessCounter> from = query.from(DBObjectAccessCounter.class); Path<DBObject> object = from.get(DBObjectAccessCounter_.object); Expression<Long> sum = builder.sumAsLong(from.get(DBObjectAccessCounter_.count)); query.multiselect(object, sum).groupBy(object); I get the following exception: ERROR: column "dbobject1_.id" must appear in the GROUP BY clause or be used in an aggregate function The generated SQL is: select dbobjectac0_.object_id as col_0_0_, sum(dbobjectac0_.count) as col_1_0_, dbobject1_.id as id1001_, dbobject1_.name as name1013_, dbobject1_.lastChanged as lastChan2_1013_, dbobject1_.type_id as type3_1013_ from DBObjectAccessCounter dbobjectac0_ inner join DBObject dbobject1_ on dbobjectac0_.object_id=dbobject1_.id group by dbobjectac0_.object_id Obviously, the first item of the select statement (dbobjectac0_.object_id) does not match the group by clause. Simplified example It does not even work for this simple example: Root<DBObjectAccessCounter> from = query.from(DBObjectAccessCounter.class); Path<DBObject> object = from.get(DBObjectAccessCounter_.object); query.select(object).groupBy(object); which returns select dbobject1_.id as id924_, dbobject1_.name as name933_, dbobject1_.lastChanged as lastChan2_933_, dbobject1_.type_id as type3_933_ from DBObjectAccessCounter dbobjectac0_ inner join DBObject dbobject1_ on dbobjectac0_.object_id=dbobject1_.id group by dbobjectac0_.object_id Does anyone know how to fix this?

  • Compile Assembly Output generated by VC++?

  • eclipse django using wrong settings.py in pythonpath

    - by user1290264
    I have pydev/django installed in eclipse, and it runs fine. However, after adding a second django project to eclipse and running the server ('http://127.0.0.1:8000') the pythonpath seems to be stuck on project2 even when I run project1. As a summary, I have two django projects: project1, project2. When I run the django server for project1 I get: Validating models... 0 errors found Django version 1.5, using settings 'project1.settings' Development server is running at 'http://127.0.0.1:8000/' Quit the server with CTRL-BREAK. The above seems to suggest that django is using the correct settings file; however, when I go to 'http://127.0.0.1:8000/' it displays the urls from project2. Also, if I go to 'http://127.0.0.1:8000/admin' the models are getting pulled from the sqlite.db file in project2 as well. I've even tried removing project2 from eclipse entirely and now at 'http://127.0.0.1:8000/admin' I get this error: Python Path: ['C:\Users\Brad\workspaces\In Progress\project2', 'C:\Users\Brad\workspaces\In Progress\project2', 'C:\Python27\DLLs', 'C:\Python27\lib', 'C:\Python27\lib\plat-win', 'C:\Python27\lib\lib-tk', 'C:\Python27', 'C:\Python27\lib\site-packages', 'C:\Windows\system32\python27.zip'] If I run the server on a different port with project1 the path seems to be fine: runserver 7000 --noreload Then 'http://127.0.0.1:7000/' uses project1's paths, but it doesn't seem like I should have to do this. Note: I have setup the run configurations as correctly as I know how. In the main tab, the project and main module both point to the correct project (project1), and the "PYTHONPATH that will be used in the run:" includes project1. Also, I have cleared my browser history, cookies, and everything that chrome would let me delete.

  • Calling functions from the Immediate Window during debugging -- advanced Visual Studio kung-fu test

    - by kizzx2
    I see some related questions have been asked, but they're either too advanced for me to grasp or lacking a step-by-step guide from start to finish (most of them end up being insider talk of their own experiment results). OK here it is, given this simple program: #include <stdio.h> #include <string.h> int main() { FILE * f; char buffer[100]; memset(buffer, 0, 100); fun(); f = fopen("main.cpp", "r"); fread(buffer, 1, 99, f); printf(buffer); fclose(f); return 0; } What it does is basically print itself (assume file name is main.cpp). Question How can I have it print another file, say foobar.txt without modifying the source code? It has something to do with running it through VS's, stepping through the functions and hijacking the FILE pointer right before fread() is called. No need to worry about leaking resources by calling fclose(). I tried the simple f = fopen("foobar.txt", "r") which gave CXX0017: Error: symbol "fopen" not found Any ideas?

  • Codeigniter common templates

    - by Darthg8r
    Let's say that I have a website that has 100 different pages. Each page uses a common header and footer. Inside the header is some dynamic content that comes from a database. I'd like to avoid having to have code in every single controller and action that passes this common code into the view. function index() { // It sucks to have to include this on every controller action. data['title'] = "This is the index page"; data['currentUserName'] = "John Smith"; $this->load->view("main_view", data); } function comments() { // It sucks to have to include this on every controller action. data['title'] = "Comment list"; data['currentUserName'] = "John Smith"; $this->load->view("comment_view", data); } I realize that I could refactor the code so that the common parts are in a single function and the function is called by the action. Doing so would reduce SOME of the pain, but it still doesn't feel right since I'd still have to make a call to that function every time. What's the correct way to handle this?

  • Temporary non-const istream reference in constructor (C++)

    - by Christopher Bruns
    It seems that a constructor that takes a non-const reference to an istream cannot be constructed with a temporary value in C++. #include <iostream> #include <sstream> using namespace std; class Bar { public: explicit Bar(std::istream& is) {} }; int main() { istringstream stream1("bar1"); Bar bar1(stream1); // OK on all platforms // compile error on linux, Mac gcc; OK on Windows MSVC Bar bar2(istringstream("bar2")); return 0; } This compiles fine with MSVC, but not with gcc. Using gcc I get a compile error: g++ test.cpp -o test test.cpp: In function ‘int main()’: test.cpp:18: error: no matching function for call to ‘Bar::Bar(std::istringstream)’ test.cpp:9: note: candidates are: Bar::Bar(std::istream&) test.cpp:7: note: Bar::Bar(const Bar&) Is there something philosophically wrong with the second way (bar2) of constructing a Bar object? It looks nicer to me, and does not require that stream1 variable that is only needed for a moment.

  • C# Byte[] to Url Friendly String

    - by LorenVS
    Hello, I'm working on a quick captcha generator for a simple site I'm putting together, and I'm hoping to pass an encrypted key in the url of the page. I could probably do this as a query string parameter easy enough, but I'm hoping not too (just because nothing else runs off the query string)... My encryption code produces a byte[], which is then transformed using Convert.ToBase64String(byte[]) into a string. This string, however, is still not quite url friendly, as it can contain things like '/' and '='. Does anyone know of a better function in the .NET framework to convert a byte array to a url friendly string? I know all about System.Web.HttpUtility.UrlEncode() and its equivalents, however, they only work properly with query string parameters. If I url encode an '=' inside of the path, my web server brings back a 400 Bad Request error. Anyways, not a critical issue, but hoping someone can give me a nice solution **EDIT: Just to be absolutely sure exactly what I'm doing with the string, I figured I would supply a little more information. The byte[] that results from my encryption algorithm should be fed through some sort of algorithm to make it into a url friendly string. After this, it becomes the content of an XElement, which is then used as the source document for an XSLT transformation, and is used as a part of the href attribute for an anchor. I don't believe the xslt transformation is causing the issues, since what is coming through on the path appears to be an encoded query string parameter, but causes the HTTP 400 I've also tried HttpUtility.UrlPathEncode() on a base64 string, but that doesn't seem to do the trick either (I still end up with '/'s in my url)**

  • WPF DataBinding to standard CLR properties in code-behind

    - by nukefusion
    Hi everyone, Just learning WPF databinding and have a gap in my understanding. I've seen a few similar questions on StackOverflow, but I'm still struggling in determining what I have done wrong. I have a simple Person class with a Firstname and Surname property (standard CLR properties). I also have a standard CLR property on my Window class that exposes an instance of Person. I've then got some XAML, with two methods of binding. The first works, the second doesn't. Can anybody help me to understand why the second method fails? There's no binding error message in the Output log. <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:WpfApplication1" Title="Window1" Height="300" Width="300" DataContext="{Binding RelativeSource={RelativeSource Self}, Path=MyPerson}"> <StackPanel> <Label>My Person</Label> <WrapPanel> <Label>First Name:</Label> <Label Content="{Binding RelativeSource={RelativeSource AncestorType=Window, Mode=FindAncestor}, Path=MyPerson.FirstName}"></Label> </WrapPanel> <WrapPanel> <Label>Last Name:</Label> <Label Content="{Binding MyPerson.Surname}"></Label> </WrapPanel> </StackPanel> Edit: Ok, thanks so far. I've changed the second expression to: <Label Content="{Binding Surname}"></Label> I still can't get it to work though!

  • Powershell - Splitting string into seperate components

    - by TheD
    I am writing a script which will basically do the following: Read from a text file some arguements: DriveLetter ThreeLetterCode ServerName VolumeLetter Integer Eg. W MSS SERVER01 C 1 These values happen to form a folder destination W:\MSS\, and a filename which works in the following naming convention: SERVERNAME_VOLUMELETTER_VOL-b00X-iYYY.spi - Where The X is the Integer above The value Y I need to work out later, as this happens to be the value of the incremental image (backups) and I need to work out the latest incremental. So at the moment -- Count lines in file, and loop for this many lines. $lines = Get-Content -Path PostBackupCheck-Textfile.txt | Measure-Object -Line for ($i=0; $i -le $lines.Lines; $i++) Within this loop I need to do a Get-Content to read off the line I am currently looking at i.e. line 0, line 1, line 2, as there will be multiple lines in the format I wrote at the beginning and split the line into an array, whereby each part of the file, as seen above naming convention, is in a[0], a[1], a[2]. etc The reason for this is because, I need to then sort the folder that contains these, find the latest file, by date, and take the _iXXX.spi part and place this into the array value a[X] so I then have a complete filename to mount. This value will replace iYYY.spi It's a little complex because I also have to make sure when I do a Get-ChildItem with -Include before I sort it all by date, I am only including the filename that matches the arguements fed to it from the text file : So, SERVER01_C_VOL-b001-iYYY.spi and not anything else. i.e. not SERVER01_D_VOL-b001-iYYY.spi Then take the iYYY value from the sort on the Get-ChildItem -Include and place that into the appropriate array item. I've literally no idea where to start, so any ideas are appreciated! Hopefully I've explained in enough detail. I have also placed the code on Pastebin: http://pastebin.com/vtFifTW6 Thanks!

  • C Programming Logic Error?

    The following code compiles fine, but does not allow the user to choose whether or not the program is to run again. After giving the user the answer, the program automatically terminates. I placed the main code in a "do while" loop to have the ability to convert more than one time if I wanted too.

Compiling on MacBookPro running Snow Leopard. #include <stdio.h> #include <stdlib.h> int main(void) { char anotherIteration = 'Y'; do { const float Centimeter = 2.54f; float inches = 0.0f; float result = 0.0f; // user prompt printf("\nEnter inches: "); scanf("%f", &inches); if (inches < 0) { printf("\nTry again. Enter a positive number.\n"); break; } else { // calculate result result = inches * Centimeter; } printf("%0.2f inches is %0.2f centimeters.\n", inches, result); // flush input fflush(stdin); // user prompt printf("\nWould you like to run the program again? (Y/N): "); scanf("%c", &anotherIteration); if ((anotherIteration != 'Y') || (anotherIteration != 'N')) { printf("\nEnter a Y or a N."); break; } } while(toupper(anotherIteration == 'Y')); printf("Program terminated.\n"); return 0; }

  • Sending items in a LINQ sequence to a method that returns void

    - by generalt
    Hello all. Often while I'm dealing with LINQ sequences, I want to send each item to a method returning void, avoiding a foreach loop. However, I haven't found an elegant way to do this. Today, I wrote the following code: private StreamWriter _sw; private void streamToFile(List<ErrorEntry> errors) { if (_sw == null) { _sw = new StreamWriter(Path.Combine (Path.GetDirectoryName(_targetDatabasePath), "errors.txt")); } Func<ErrorEntry, bool> writeSelector = (e) => { _sw.WriteLine(getTabDelimititedLine(e)); return true; }; errors.Select(writeSelector); _sw.Flush(); } As you can see, I write a lambda function that just returns true, and I realize that the Select method will return a sequence of booleans- I'll just ignore that sequence. However, this seems a little bit noobish and jank. Is there any elegant way to do this? Or am I just misapplying LINQ? Thanks.

  • displaying video from webcam in OpenCV

    - by Adi
    hi all, I have installed VS2008 and am able to run the demo codes "camshiftdemo and lkdemo " which comes in the opencv library. With this done, now I am trying to run some simple codes from the internet to get acquainted with the OpenCV. I am just trying to display video from webcam and I am getting the following error.. Error I am getting is : Unhandled exception at 0x5e7e3d10 (highgui200.dll) in opencv.exe: 0xC0000005: Access violation reading location 0x719b3856. The code I am trying to run is : include include void main(int argc,char argv[]) { int c; IplImage color_img; CvCapture* cv_cap = cvCaptureFromCAM(-1); // -1 = only one cam or doesn't matter cvNamedWindow("Video",1); // create window for(;;) { color_img = cvQueryFrame(cv_cap); // get frame if(color_img != 0) cvShowImage("Video", color_img); // show frame c = cvWaitKey(10); // wait 10 ms or for key stroke if(c == 27) break; // if ESC, break and quit } /* clean up */ cvReleaseCapture( &cv_cap ); cvDestroyWindow("Video"); } Any help in this will be greatly appreciated. Thanks aditya

  • TFS 2010 Build gives WorkItemStore error when Create Work Item on Failure is enabled

    - by Derek Morrison
    I'm using TFS 2010 Build. I have a build definition that uses the DefaultTemplate.xaml template that's stock in TFS 2010, and the Create Work Item on Failure property is set to True in the build definition. I deliberately made a change in my project that breaks the build. When the build runs, I see the compilation error reflected in the TFS Build log within Visual Studio, but I get the error "Value cannot be null. Parameter name: WorkItemStore" when TFS Build next tries to generate a Work Item for the broken build. I tracked down the activity in DefaultTemplate.xaml (see the rather lengthy path to it below) where the Work Item is created for a broken build, and I see it uses the Microsoft.TeamFoundation.Build.Workflow.Activities.OpenWorkItem class to create the Work Item. The appropriate values seemed to be filled out in the Properties window for the Create Work Item activity, so I don't see where I can pass WorkItemStore to it and I don't even know appropriate values for this setting. Path to the Create Work Item activity: Process Sequence Run On Agent Try Compile, Test, and Associate Changesets and Work Items Sequence Compile, Test, and Associate Changesets and Work Items Try Compile and Test Compile and Test For Each Configuration in BuildSettings.PlatformConfigurations Compile and Test for Configuration If BuildSettings.HasProjectsToBuild For Each Project in BuildSettings.ProjectsToBuild Try to Compile the Project Handle Exception If CreateWorkItem Create Work Item for non-Shelveset Builds Create Work Item

  • text not wrapping around some floated images, wraps in IE & FF but not chrome, safari

    - by Hartley
    This is unlike anything I've read about and I've been totally scratching my head for the last few hours trying to figure out what's going on. I have a hand-coded site @ hartbro.com Part of the site is a blog, in which I include pictures. Here's the HTML code around one of the images that's causing trouble. <a href="blogcontent/090811.jpg" class="img"> <img src="blogcontent/090811.jpg" alt="Downed trees" width="25%" class="floatright" /></a> The storm left as quickly as it came. The sky cleared up and we were glad that the oppressive heat had let up. What I've noticed is that, on some of the blog entries that include more than one image, the 2nd image isn't really floating like its supposed to be, with the text wrapping around it. I figure its got to be some sort of conflict with some CSS that I have that's causing the problem but I just can't figure out what it is. I don't understand how it works in FF & IE but not Chrome or Safari?? Here's all of the relevant CSS, let me know if you need anything else. Thanks in advance. img{ margin:10px; } img.floatleft{ float:left; } img.floatright{ float:right; } edit: here's an screen-shot of what's happening.
