  • Dynamically set generic type argument

    - by fearofawhackplanet
    Following on from my question here, I'm trying to create a generic value equality comparer. I've never played with reflection before so not sure if I'm on the right track, but anyway I've got this idea so far: bool ContainSameValues<T>(T t1, T t2) { if (t1 is ValueType || t1 is string) { return t1.Equals(t2); } else { IEnumerable<PropertyInfo> properties = t1.GetType().GetProperties().Where(p => p.CanRead); foreach (var property in properties) { var p1 = property.GetValue(t1, null); var p2 = property.GetValue(t2, null); if( !ContainSameValues<p1.GetType()>(p1, p2) ) return false; } } return true; } This doesn't compile because I can't work out how to set the type of T in the recursive call. Is it possible to do this dynamically at all? There are a couple of related questions on here which I have read but I couldn't follow them enough to work out how they might apply in my situation.

  • Jquery and Ajax to Dynamically load IFrame

    - by JCHASE11
    I have a script that dynamically loads iframes inside a webpage. You can see the demo here: DEMO I want to use jquery to achieve the same rseult, but with a nice sliding effect. Basically, I have 10 links on a page. When the link is clicked, I want the iframe window to load in the new content and apply an effect to the transition. Does anyone know of any plugins that exist for this. I am not experienced enough to write a script from scratch, so any help would be much appreciated!

  • Loading tables dynamically with NHibernate

    - by Trevor Goertzen
    I'm working on a project that requires me to load tables based on table names stored in another table. More tables will be added to the DB (and by someone else), so creating NHibernate mapping files for each table isn't an option. Does anyone know if it is possible to load tables dynamically using NHibernate? Edit: I should add that I'm on .NET 2.0, so I can't use Fluent NHibernate. Thanks for the suggestion though guys. I will use that as evidence in convincing my associates to upgrade.

  • how to store dynamically generated pages in html?

    - by Dharmik Bhandari
    I'm working on ASP.net MVC3 Web application that is facing scalability issue. For improving performance I want to store dynamically generated pages in html and serve them from generated html directly rather then querying database for each page request. I'm sure this will dramatically increase performance. Can any one share any hint / example / tutorial on how to do it? And what are challenges? I would also like to know how others are handling performance issue for large e-commerce sites with at-least thousand categories and 200k products with at least 200-500 concurrent visitors? What are the best approaches? Thanks in advance.

  • adding multiple rows to jquery Datatables dynamically

    - by arrowill12
    I am trying to add multiple rows at once to a jQuery Datatable. I would like to be able to create a string such as the one below and call a function to add these elements as rows in the table. Is there a function that will allow me to do this? var trString = "<tr class='custom class'><td></td><td></td></tr><tr class='custom class'><td></td><td></td></tr><tr class='custom class'><td></td><td></td></tr>" I have seen the fnAddData function but I would not be able to add my custom classes dynamically to the rows using that function. Also I have tried fnAddTr but I keep receiving an error saying my object does not have the method "getelementsByTagName" again, is there a function that will allow me to add a string of "" to a datatable?

  • is it possible to dynamically set the level of for loop nesting

    - by galaxy
    I'm working out an algorithm to get permutations like 123 132 213 231 312 321 I'm doing it using nested foreach loops. for (..) { for(..) { for(..) { echo $i . $j . $k . "<br />"; } } } Problem is those # of nested loops are optimized for 3-spot permutations. How can I could I dynamically set the number of nested for loops to generate 4-letter or 5-letter permutations?

  • Adding Message Part dynamically in Receive Pipeline

    - by Sean
    Hello, I tried to create a custom pipeline component that takes a message and attaches additional another part dynamically (during Disassemble stage). I haven't set up a send port, so that I can see what BizTalk is trying to process. I can see only the body part, the additional part doesn't show up. This is the code I used: var part = pc.GetMessageFactory().CreateMessagePart(); part.Data = new MemoryStream(new byte[] {1, 2, 3, 4, 5}); inmsg.AddPart("another_part", part, false); Thank you.

  • Create pdf file dynamically in vb.net for .net 1.1 framework

    - by Urbycoz
    I need to create a pdf file dynamically in vb.net. It needs to contain several images and lines of text. I am using VS 2003, so whatever solution I use will need to be compatible with the .net 1.1 framework. The current method I am using is wpcubed, but this requires that all images be converted to bmp format before adding them to the pdf, which can be extremely slow when dealing with a large number of images. I am aware that there are an awful lot of other 3rd party products that claim to do this, and I have had a search through them. But without registering, downloading, installing and writing code to use each of them in turn, it is very difficult to differentiate between them. So far I have looked into evo pdf and pdfsharp but neither seem to work with .net 1.1. (Although they don't make this abundantly clear.) Has anyone else found a method that works and they would recommend (a free one-if possible)?

  • ASP.NET Build Images Links Dynamically

    - by coson
    Good Day, I am developing a website that has product images on an external server. I have code that tests to see if the image exists like (pseudo code): DynamicString = FunctionThatCreatesDynamicString() ' DynamicString = "http://external_server/path/to/file1.jpg" If ImageExists(DyanmicString) = StatusCode.200 Then ' Embed link in ASP.NET page Else ' Embed not found image in ASP.NET page End If My code builds fine and appears to execute. The problem occurs when I attempt to view the external link in a browser, the image appears properly (I have to authenticate first, but that's OK considering I'm on an internal network and this app will be used internally). However, when I attempt the view the source in my generated HTML page, I am seeing the image to the "Not Found" image when I know the image is there. I compared all the characters in my dynamically assembled to the external link and all the characters are matching up correctly. I'm wondering if the authentication has anything to do with why the image is not rendering properly on my rendered HTML. Any thoughts? TIA, coson

  • Dynamically/recursively building hashes in Perl?

    - by Gaurav Dadhania
    I'm quite new to Perl and I'm trying to build a hash recursively and getting nowhere. I tried searching for tutorials to dynamically build hashes, but all I could find were introductory articles about hashes. I would be grateful if you point me towards the right direction or suggest a nice article/tutorial. I'm trying to read from a file which has paths in the form of one/two/three four five/six/seven/eight and I want to build a hash like VAR = { one : { two : { three : "" } } four : "" five : { six : { seven : { eight : "" } } } } The script I'm using currently is : my $finalhash = {}; my @input = <>; sub constructHash { my ($hashrf, $line) = @_; @elements = split(/\//, $line); if(@elements > 1) { $hashrf->{shift @elements} = constructHash($hashrf->{$elements[0]}, @elements ); } else { $hashrf->{shift @elements} = ""; } return $hashrf; } foreach $lines (@input) { $finalhash = constructHash($finalhash, $lines); }

  • Using a Time Zone Conversion When Dynamically Generating Results

    - by John
    Hello, If I understand correctly, the code below converts $row["datesubmitted"] from one timezone to another. I would like to print the converted $row["datesubmitted"] dynamically in an HTML table. Is there a way that I can apply the conversion below for each row that is pulled from MySQL? I assume that I can't just plug $row["dt"] into the code since there is no field called "dt" in the MySQL that I am using. Thanks in advance, John $dt = new DateTime($row["datesubmitted"], $tzFrom); $dt->setTimezone($tzTo);

  • dynamically updating a datagrid from a XML file c# 3.5

    - by Farstucker
    I have a datagrid that is populated via XML file when the form loads. Everything is working great but I would like the datagrid to update dynamically when a new order is received (Separate class receives a data stream and updates the file). Im looking for suggestions on how this should be done. (ie using a timer update every second, or monitor the file using FileSystemWatcher.. etc) Since where here, I might as well mention that in order to update the datagrid Im clearing the whole data set and Re-reading the file using: DataSet.Clear(); DataSet.ReadXml("file.xml"); dataGridView1.DataSource = DataSet; if this is not the proper approach, please offer any alternate suggestions.

  • How to dynamically assigning style properties to element?

    - by poo
    function styling(elem, props) { for (var i in props) { if (i == "color") { elem.style.color = props[i].toString(); } if (i == "background") { elem.style.background = props[i].toString(); } } Using it: styling(links, { color: "blue", background: "yellow" }); I'm not really happy with the if-clauses and I want to dynamically add the style properties to the element, but I'm not sure how to do it. Someone out there would know how to do it? Solved it function styling(elem, props) { for (var i in props) { elem.style[i] = props[i].toString(); } } That seems to do the trick.

  • c arrays: setting size dynamically?

    - by user336994
    Hello, I am new to C programming. I am trying to set the size of the array using a variable but I am getting an error: Storage size of 'array' isn't constant !! 01 int bound = bound*4; 02 static GLubyte vertsArray[bound]; I have noticed that when I replace bounds (within the brackets on line 02) with the number say '20', the program would run with no problems. But I am trying to set the size of the array dynamically ... Any ideas why I am getting this error ? thanks much,

  • Style Data in a gridview which dynamically generates the columns

    - by Coesy
    I have built a dynamic gridview using the following code grdVariants.Columns.Clear(); int i = 0; foreach (DataColumn column in options.Columns) { grdVariants.Columns.Add(new GridViewColumn { Header = column.ColumnName, DisplayMemberBinding = new Binding(string.Format("[{0}]", i++)) }); } This will dynamically generate my columns at runtime, I then bind the data using lstVariantsGrid.DataContext = options; lstVariantsGrid.Items.Refresh(); This all works great and shows the data in the correct columns etc, the only issue i have is that I can't style the rows like I would in xaml as it is all an unknown quantity until runtime. Can anyone offer some advice on how I might go about doing this? One of the biggest problems I have is that one of the columns needs to display the image rather than just the path which it currently shows, as well as fiddling with fonts and colors etc. Thanks for your time.

  • Dynamically loading JavaScript synchronously

    - by spoon16
    I'm using the module pattern, one of the things I want to do is dynamically include an external JavaScript file, execute the file, and then use the functions/variables in the file in the return { } of my module. I can't figure out how to do this easily. Are there any standard ways of performing a pseudo synchronous external script load? function myModule() { var tag = document.createElement("script"); tag.type = "text/javascript"; tag.src = "http://some/script.js"; document.getElementsByTagName('head')[0].appendChild(tag); //something should go here to ensure file is loaded before return is executed return { external: externalVariable } }

  • innerHTML of dynamically added element not updating in Chrome

    - by Sara Chipps
    I'm modifying a dynamically created input element by setting the innerHTML, when I view the element in the DOM Inspector I can see that the values I passed are in the input. However, I can't see it on the page? Is there a refresh() function that I should be calling after setting the value? I have tried innerText, and value and gotten the same results. Here is how I am setting it: $("input[name='group']")[0].innerHTML = groups; (as far as the JS set and the JQuery selector I have found chrome plugins to be fickle this way)

  • Dynamically render partial templates using mustache

    - by btakita
    Is there a way to dynamically inject partial templates (and have it work the same way in both Ruby & Javascript)? Basically, I'm trying to render different types of objects in a list. The best I can come up with is this: <div class="items"> {{#items}} <div class="item"> {{#is_message}} {{< message}} {{/is_message}} {{^is_message}} {{#is_picture}} {{< picture}} {{/is_picture}} {{^is_picture}} {{/is_picture}} {{/is_message}} </div> {{/items}} </div> For obvious reasons, I'm not super-psyched about this approach. Is there a better way? Also note that the different types of models for the views can have non-similar fields. I suppose I could always go to the lowest common denominator and have the data hash contain the html, however I would rather use the mustache templates.

    I have the same query in a stored procedure that needs to be executed on different servers and databases according to parameters. How can I arrange this without exec or sp_executesql? I'm using SQL Server 2008. Thank you. UPDATE I've found some links http://www.eggheadcafe.com/software/aspnet/29397800/dynamically-specify-serve.aspx http://www.sommarskog.se/dynamic_sql.html Is using SYNONYM possible solution? If yes, than how? UPDATE 2 I forgot to mention that all this servers are linked to the server where stored procedure is stored.

  • Dynamically adding @property in python

    - by rz
    I know that I can dynamically add an instance method to an object by doing something like: import types def my_method(self): # logic of method # ... # instance is some instance of some class instance.my_method = types.MethodType(my_method, instance) Later on I can call instance.my_method() and self will be bound correctly and everything works. Now, my question: how to do the exact same thing to obtain the behavior that decorating the new method with @property would give? I would guess something like: instance.my_method = types.MethodType(my_method, instance) instance.my_method = property(instance.my_method) But, doing that instance.my_method returns a property object.

  • Dynamically create labels in gas macros?

    - by pgod
    Hi everyone, I would like to dynamically create a set of labels in an assembly function using a gas macro. I would like to do something like this: .macro set_up_jumptab_entry prefix, from=0, to=10 .quad \prefix_\item .if \to-\from set_up_jumptab_entry \prefix,"(\from+1)",\to .endif .endm set_up_jumptab_entry myfunc 0 10 Here \prefix_\item would be something like myfunction_7. Now, I can find lots of examples of recursive invocation, but I haven't found one of just label concatenation involving passed-in macro arguments. Gas is quite poorly documented, so answering this question is difficult for me. Can you concatenate arguments to macros with other tokens to make single tokens? What's your favorite gas assembler reference?

  • Dynamically create PHPUnit tests from data-file

    - by DeletedAccount
    I have a data file with input and expected outputs. An example could be: input: output: 2 3 3 5 4 Exception 5 8 ... ... Currently I have a custom solution to read from the data file and perform a test for each {input,output} pair. I would like to convert this into a PHPUnit based solution and I would like to have one test per input using the test name forXassertY. So the first three tests would be called for2assert3(), for3assert5() and for4assertException(). I do not want to convert my existing data to tests if it's possible to create the test methods dynamically and keep the data file as the basis of these tests. I want to convert it to PHPUnit as I want to add some other tests later on and also process and view the output using Hudson. Suggestions?

  • c# Dynamically generated controls issue.

    - by Thomas
    Good Day I have a form with a panel docked in it. I then dynamically create 15 panels (named: panel_n) and 15 pictureboxes (named: picturebox_n) on the primary panel (named ContainerPanel). When dragging the any picturebox over a panel (panel_n) created using the relevant mouse events. I would like to get the panel's name that the picture box was dragged over. The mouse cursor seems to be captured. I have tried creating a IMessageFilter interface, but there are still no events that trigger when dragging one of the pictureboxes over any one of the panels. The ClientRectangle.IntersectsWith function also does not work as the co-ords are always 0,0. All I need is the panel name where the picturebox was dragged over (preferably on the mouseup event)
