  • Previously working emberjs1.0-pre form on jsfiddle returns "error": "Please use POST request"

    - by brg
    This code ** http://jsfiddle.net/wagenet/ACzaJ/8/ ** was working a few days ago, when i returned to it today, it throws {"error": "Please use POST request"}, when i click add button Also the jsfiddle editor.js always throws exception on this line: function stop(){cc = stop; throw StopIteration;}; Does anyone knows the cause of this issue. Many thanks Update 1 Based on @Peter Wagenet's suggestions below, the form now logs entries or inputs to the console but it doesn't display on the result section of jsfiddle instead what is displayed on jsfiddle result section or page is still this error {"error": "Please use POST request"} ** http://jsfiddle.net/ACzaJ/18/ Update 2 In this fiddle, http://jsfiddle.net/ACzaJ/19/, i have successfully eliminated this error {"error": "Please use POST request"} by adding event.preventDefault(); to the submit action in Todos.TodoFormView. That allows us to use arbitrary view methods as action handlers. The existing issue is that the input to the form, only displays on the console and not on jsfiddle result section, though no error displays on the result section, there is a new error appearing in the console of the updated fiddle: Uncaught Error: Cannot perform operations on a Metamorph that is not in the DOM. Finally solved I needed to comment out App.initialize() for it to work as expected. This the working fiddle ** http://jsfiddle.net/ACzaJ/20/. I don't know why that is so, but my guess is that, App.initialize works with other parts like the router for routing, ApplicationController and ApplicationView with {{outlet}} in the handlebars, which i didn't need for this fiddle. Finally Finally and completely solved This ** http://jsfiddle.net/tQWn8/ works with App.initialize. But you have to declare all those components above and pass the router to App.initialize, like this App..initialize(router). If you don't do this, then you will get the old error Uncaught Error: Cannot perform operations on a Metamorph that is not in the DOM.

  • Passing char * into fopen with C.

    - by Rhys
    Hey there, I'm writing a program that passes data from a file into an array, but I'm having trouble with fopen (). It seems to work fine when I hardcode the file path into the parameters (eg fopen ("data/1.dat", "r");) but when I pass it as a pointer, it returns NULL. Note that line 142 will print "data/1.dat" if entered from command line so parse_args () appears to be working. 132 int 133 main(int argc, char **argv) 134 { 135 FILE *in_file; 136 int *nextItem = (int *) malloc (sizeof (int)); 137 set_t *dictionary; 138 139 /* Parse Arguments */ 140 clo_t *iopts = parse_args(argc, argv); 141 142 printf ("INPUT FILE: %s.\n", iopts->input_file); /* This prints correct path */ 143 /* Initialise dictionary */ 144 dictionary = set_create (SET_INITAL_SIZE); 145 146 /* Use fscanf to read all data values into new set_t */ 147 if ((in_file = fopen (iopts->input_file, "r")) == NULL) 148 { 149 printf ("File not found...\n"); 150 return 0; 151 } Thanks!

  • Which knowledge base/rule-based inference engine to choose for real time Runway incursion prevention

    - by Piligrim
    Hello, we are designing a project that would listen to dialog between airport controllers and pilots to prevent runway incursions (eg. one airplane is taking off while other is crossing the runway). Our professor wants us to use Jena for knowledge base (or anything else but it should be some sort of rule-based engine). Inference is not the main thing in Jena and there's not much documentation and examples of this. So we need an engine that would get messages from pilots as input and output possible risks of incursion or any other error in message protocol. It should be easy to write rules, and should be easy to provide engine with real time data. I image it something like this: A pilot sends a message that he lands on some runway, the system remembers that the runway is busy and no one should cross it If someone is given an instruction to cross this runway, the engine should fire a rule that something is wrong When the pilot sends a message that he left the runway and goes to the gate, the system clears the runway and lets other planes to use it. So is Jena, or prolog or any other rules engine suitable for this? I mean it is suitable, but do we really need to use it? I asked the prof. if we could just keep state of the runway and use some simple checks based on messages we receive and he said that it is not scalable and we need the knowledge base. Can someone give me any advise on which approach to use for this system? If you recommend k.b., then which one should we use? The project is written in java. Thank you.

  • jquery autocomplete & masterpage

    - by Caroline
    Hi everyone, first time posting here, so hello to all :-) I'm pretty new to the jQuery thing, but I got the autocomplete function running quite well on a simple aspx page. Now I wanted to use the same function on an aspx-page with a masterpage, and it doesnt work anymore. this test function works fine: $(document).ready(function () { $("[id$=AlertButton]").click(function () { alert("Welcome jQuery !"); }); }); but this simply does nothing: $(document).ready(function () { $("[id$=Suchen]").autocomplete("AutocompleteData.ashx"); }); the javascript and css files are loaded in the master page, just above the contentplaceholder. the code within the contentplaceholder looks like this: <atlas:ScriptManager id="SM1" runat="server" EnablePartialRendering="true" > <Services> <atlas:servicereference path="~/xxxxx.asmx" /> </Services> </atlas:ScriptManager> <script type="text/javascript"> $(document).ready(function () { $("[id$=Suchen]").autocomplete("AutocompleteData.ashx"); }); </script> <br /> <asp:Button ID="AlertButton" runat="server" Text="Button" /> <br /> <asp:TextBox ID="Suchen" Width="250" runat="server"></asp:TextBox> if I execute the .ashx page on its own, it fires back the expected data... I've been browsing tons of pages, but couldn't resolve the issue. I'd be glad for any input!!! Thanks alot & all the best, Caroline

  • Suggestions for GUI of a multiledia messaging application in J2ME

    - by awaghad-ashish
    Hello everyone, We have developed a messaging application in j2me which adds text message, gets pictures from gallery and attaches them to the message etc and sends it over to a server after encryption, i.e. the client wants the messages to be encrypted. The app is ready but the only problem is that the GUI of the app looks miserable compared to the GUI of native messaging application on Nokia phones. Our GUI consists of a texfield for adding recipients i.e. the user clicks "options" to "add recipients" and is taken to a new form where contacts are shown. but the textfield is not in one line (like in case of native app). Also, we need the user to input the text message in a textField since we cannot have textbox inside a form (but the native app has a textbox as well as a textField ). Are there any ways to achieve such GUIs (one-line textfields, textbox like thing inside a form)? I hope you all understand what I mean, any kind of help will be appreciated. Thanks and regards, Ashish.

  • How to serve tiff WMS imagery through GeoServer

    - by mikem419
    Ok so I am new to the GeoServer/database world. I am a student intern and I have been given the task of setting up a WMS using GeoServer. I have never done any database work before this so bare with me if my questions leave out important information. I am using GeoServer 2.0.1 in standalone mode (downloaded using Jetty) with PostgreSQL 8.4 installed. I went through nyc_roads and nyc_buildings install demo in the GeoServer documentation but I still do not understand how I should go about serving up some test images. I noticed that the nyc_roads setup included a .sql file that was responsible for setting up the nyc_buildings database. I do not know how/where this file was generated. Our test images are .tiff and .jpeg. I have successfully been able to do a WMS call on the local GeoServer machine, and have opened the included demo imagery. I now wish to add these .tiff and .jpeg images to GeoServer and access them through WMS. I have tried copying the images to the GeoServer data directory,adding a new data store, and layers, but I always receive an error regarding the "input stream." Again I am very sorry if I am leaving out allot of vital information, this is as much as I know. thanks!

  • Passing string with (accidental) escape character loses character even though it's a raw string

    - by Steen
    I have a function with a python doctest that fails because one of the test input strings has a backslash that's treated like an escape character even though I've encoded the string as a raw string. My doctest looks like this: >>> infile = [ "Todo: fix me", "/** todo: fix", "* me", "*/", r"""//\todo stuff to fix""", "TODO fix me too", "toDo bug 4663" ] >>> find_todos( infile ) ['fix me', 'fix', 'stuff to fix', 'fix me too', 'bug 4663'] And the function, which is intended to extract the todo texts from a single line following some variation over a todo specification, looks like this: todos = list() for line in infile: print line if todo_match_obj.search( line ): todos.append( todo_match_obj.search( line ).group( 'todo' ) ) And the regular expression called todo_match_obj is: r"""(?:/{0,2}\**\s?todo):?\s*(?P<todo>.+)""" A quick conversation with my ipython shell gives me: In [35]: print "//\todo" // odo In [36]: print r"""//\todo""" //\todo And, just in case the doctest implementation uses stdout (I haven't checked, sorry): In [37]: sys.stdout.write( r"""//\todo""" ) //\todo My regex-foo is not high by any standards, and I realize that I could be missing something here. EDIT: Following Alex Martellis answer, I would like suggestions on what regular expression would actually match the blasted r"""//\todo fix me""". I know that I did not originally ask for someone to do my homework, and I will accept Alex's answer as it really did answer my question (or confirm my fears). But I promise to upvote any good solutions to my problem here :) I'm using Python 2.6.4 (r264:75706, Dec 7 2009, 18:45:15) Thank you for reading this far (If you skipped directly down here, I understand)

  • The cost of passing by shared_ptr

    - by Artem
    I use std::tr1::shared_ptr extensively throughout my application. This includes passing objects in as function arguments. Consider the following: class Dataset {...} void f( shared_ptr< Dataset const > pds ) {...} void g( shared_ptr< Dataset const > pds ) {...} ... While passing a dataset object around via shared_ptr guarantees its existence inside f and g, the functions may be called millions of times, which causes a lot of shared_ptr objects being created and destroyed. Here's a snippet of the flat gprof profile from a recent run: Each sample counts as 0.01 seconds. % cumulative self self total time seconds seconds calls s/call s/call name 9.74 295.39 35.12 2451177304 0.00 0.00 std::tr1::__shared_count::__shared_count(std::tr1::__shared_count const&) 8.03 324.34 28.95 2451252116 0.00 0.00 std::tr1::__shared_count::~__shared_count() So, ~17% of the runtime was spent on reference counting with shared_ptr objects. Is this normal? A large portion of my application is single-threaded and I was thinking about re-writing some of the functions as void f( const Dataset& ds ) {...} and replacing the calls shared_ptr< Dataset > pds( new Dataset(...) ); f( pds ); with f( *pds ); in places where I know for sure the object will not get destroyed while the flow of the program is inside f(). But before I run off to change a bunch of function signatures / calls, I wanted to know what the typical performance hit of passing by shared_ptr was. Seems like shared_ptr should not be used for functions that get called very often. Any input would be appreciated. Thanks for reading. -Artem

  • Extracting bool from istream in a templated function

    - by Thomas Matthews
    I'm converting my fields class read functions into one template function. I have field classes for int, unsigned int, long, and unsigned long. These all use the same method for extracting a value from an istringstream (only the types change): template <typename Value_Type> Value_Type Extract_Value(const std::string& input_string) { std::istringstream m_string_stream; m_string_stream.str(input_string); m_string_stream.clear(); m_string_stream >> value; return; } The tricky part is with the bool (Boolean) type. There are many textual representations for Boolean: 0, 1, T, F, TRUE, FALSE, and all the case insensitive combinations Here's the questions: What does the C++ standard say are valid data to extract a bool, using the stream extraction operator? Since Boolean can be represented by text, does this involve locales? Is this platform dependent? I would like to simplify my code by not writing my own handler for bool input. I am using MS Visual Studio 2008 (version 9), C++, and Windows XP and Vista.

    - by dexter
    I have checkBoxes in my Gridview templete columns called "Category A" and "Category B". I want Select-All functionality, i.e. when the user checks the Select-All check Box in category A column, all the checkboxes must get checked under that column. Same for Category B. I am trying with the code below. The problem with my code is, it selects all the check boxes in the entire gridview, "Category A" as well as "Category B"s checkboxes. But, I want only checkboxes selected under the same column. function SelectAllCheckboxesA(chk) { $('#<%=gvSurveys.ClientID %>').find("input:checkbox").each(function() { if (this != chk) { if ($(this).hasClass('CatA') != false) { this.checked = chk.checked; } } else { alert($(this)); } }); } <asp:GridView ID="gvSurveys" runat="server" AutoGenerateColumns="false" AllowSorting="True" Width="1500px"> <Columns> <asp:TemplateField> <HeaderTemplate>Category A <asp:CheckBox ID="chkSelectAllCatA" runat="server" Visible="false" onclick="javascript:SelectAllCheckboxesA(this);" CssClass="SACatA" /> </HeaderTemplate> <ItemTemplate> <asp:CheckBox ID="chkCatA" runat="server" Enabled="false" CssClass="CatA" /> </ItemTemplate> </asp:TemplateField> <asp:TemplateField> <HeaderTemplate> Category B <asp:CheckBox ID="chkSelectAllCatB" runat="server" Visible="false" CssClass="CatB" onclick="javascript:SelectAllCheckboxesB(this);" /> </HeaderTemplate> <ItemTemplate> <asp:CheckBox ID="chkCatB" runat="server" Enabled="false" /> </ItemTemplate> </asp:TemplateField> </Columns> </asp:GridView>

  • Why does my Sax Parser produce no results after using InputStream Read?

    - by Andy Barlow
    Hello, I have this piece of code which I'm hoping will be able to tell me how much data I have downloaded (and soon put it in a progress bar), and then parse the results through my Sax Parser. If I comment out basically everything above the //xr.parse(new InputSource(request.getInputStream())); line and swap the xr.parse's over, it works fine. But at the moment, my Sax parser tells me I have nothing. Is it something to do with is.read (buffer) section? Also, just as a note, request is a HttpURLConnection with various signatures. /*Input stream to read from our connection*/ InputStream is = request.getInputStream(); /*we make a 2 Kb buffer to accelerate the download, instead of reading the file a byte at once*/ byte [ ] buffer = new byte [ 2048 ] ; /*How many bytes do we have already downloaded*/ int totBytes,bytes,sumBytes = 0; totBytes = request.getContentLength () ; while ( true ) { /*How many bytes we got*/ bytes = is.read (buffer); /*If no more byte, we're done with the download*/ if ( bytes <= 0 ) break; sumBytes+= bytes; Log.v("XML", sumBytes + " of " + totBytes + " " + ( ( float ) sumBytes/ ( float ) totBytes ) *100 + "% done" ); } /* Parse the xml-data from our URL. */ // OLD, and works if comment all the above //xr.parse(new InputSource(request.getInputStream())); xr.parse(new InputSource(is)) /* Parsing has finished. */; Can anyone help me at all?? Kind regards, Andy

  • Websphere logs report {0} File not found, but application continues to work without issues

    - by Eric
    A websphere 6.1 server is running a struts application that seems to be working fine. In the logs, however, I'm seeing the following error message, which is being continually emailed to the support staff. com.ibm.ws.webcontainer.webapp.WebAppErrorReport: SRVE0190E: File not found: {0} at com.ibm.ws.webcontainer.webapp.WebAppDispatcherContext.sendError(WebAppDispatcherContext.java:536) at com.ibm.ws.webcontainer.srt.SRTServletResponse.sendError(SRTServletResponse.java:930) at com.ibm.ws.webcontainer.extension.DefaultExtensionProcessor.handleRequest(DefaultExtensionProcessor.java:524) at com.ibm.ws.wswebcontainer.extension.DefaultExtensionProcessor.handleRequest(DefaultExtensionProcessor.java:111) at com.ibm.ws.webcontainer.webapp.WebApp.handleRequest(WebApp.java:3129) at com.ibm.ws.webcontainer.webapp.WebGroup.handleRequest(WebGroup.java:238) at com.ibm.ws.webcontainer.WebContainer.handleRequest(WebContainer.java:811) at com.ibm.ws.wswebcontainer.WebContainer.handleRequest(WebContainer.java:1433) at com.ibm.ws.webcontainer.channel.WCChannelLink.ready(WCChannelLink.java:93) I can narrow down the issue to a single Action and JSP, which are too big to show here, but here's the action definition in struts-config.xml: <action path="/HappyDefaultThing" name="HappyDefaultThingActionForm" type="com.foo.webadministration.action.HappyDefaultThingAction" validate="true" input="/WaAssignDefaultHappyThing.jsp" scope="session"> <forward name="success" path="/WaAssignDefaultHappyThing.jsp"/> <forward name="failure" path="/WaAssignDefaultHappyThing.jsp"/> </action> As far as I can see, nothing is missing, and everything necessary is being found, but the logs say "File not found: {0}" What is "{0}"?? The stack trace only shows IBMs code, which I can't see the source of, and therefore can't trace. Is this a bug in the websphere code? I'd appreciate any help.

  • Why doesn't jquery .load() load a text file from an external website?

    In the example below, when I click the button, it says "Load was performed" but no text is shown.

  • Silverlight 4, Out of browser, Printing, Automatic updates

    - by minal
    I have a very critial business application presently running using Winforms. The application is a very core UI shell. It accepts input data, calls a webservice on my server to do the computation, displays the results on the winforms app and finally send a print stream to the printer. Presently the application is deployed using Click-once. Moving forward, I am trying to contemplate wheather I should move the application into a Silverlight application. Couple of reasons I am thinking silverlight. Gives clients the feel that it is a cloud based solution. Can be accessed from any PC. While the clickonce app is able to do this as well, they have to install an app, and when updates are available they have to click "Yes" to update. The application presently has a drop down list of customers, this list has expanded to over 3000 records. Scrolling through the list is very painful. With Silverlight I am thinking of the auto complete ability. Out of the browser - this will be handy for those users who use the app daily. I haven't used Silverlight previous hence looking for some expert advice on a few things: Printing - does silverlight allow sending raw print data to the printer. The application prints to a Zebra Thermal label printer. I have to send raw bytes to the printer with the commands. Can this be done with SL, or will it always prompt the "Print" dialog? Out of browser - when SL apps are installed as out of browser, how to updates come through, does the app update automatically or is the user prompted to opt for update?

  • R: dev.copy2pdf, multiple graphic devices to a single file, how to append to file?

    - by Timtico
    Hi everybody, I have a script that makes barplots, and opens a new window when 6 barplots have been written to the screen and keeps opening new graphic devices whenever necessary. Depending on the input, this leaves me with a potential large number of openened windows (graphic devices) which I would like to write to a single PDF file. Considering my Perl background, I decided to iterate over the different graphics devices, printing them out one by one. I would like to keep appending to a single PDF file, but I do not know how to do this, or if this is even possible. I would like to avoid looping in R. :) The code I use: for (i in 1:length(dev.list()) { dev.set(which = dev.list()[i] dev.copy2pdf(device = quartz, file = "/Users/Tim/Desktop/R/Filename.pdf") } However, this is not working as it will overwrite the file each time. Now is there an append function in R, like there is in Perl. Which allows me to keep adding pages to the existing pdf file? Or is there a way to contain the information in a graphic window to a object, and keep adding new graphic devices to this object and finally print the whole thing to a file? Other possible solutions I thought about: writing different pdf files, combining them after creation (perhaps even possible in R, with the right libraries installed?) copying the information in all different windows to one big graphic device and then print this to a pdf file.

  • AST with fixed nodes instead of error nodes in antlr

    - by ahe
    I have an antlr generated Java parser that uses the C target and it works quite well. The problem is I also want it to parse erroneous code and produce a meaningful AST. If I feed it a minimal Java class with one import after which a semicolon is missing it produces two "Tree Error Node" objects where the "import" token and the tokens for the imported class should be. But since it parses the following code correctly and produces the correct nodes for this code it must recover from the error by adding the semicolon or by resyncing. Is there a way to make antlr reflect this fixed input it produces internally in the AST? Or can I at least get the tokens/text that produced the "Tree Node Errors" somehow? In the C targets antlr3commontreeadaptor.c around line 200 the following fragment indicates that the C target only creates dummy error nodes so far: static pANTLR3_BASE_TREE errorNode (pANTLR3_BASE_TREE_ADAPTOR adaptor, pANTLR3_TOKEN_STREAM ctnstream, pANTLR3_COMMON_TOKEN startToken, pANTLR3_COMMON_TOKEN stopToken, pANTLR3_EXCEPTION e) { // Use the supplied common tree node stream to get another tree from the factory // TODO: Look at creating the erronode as in Java, but this is complicated by the // need to track and free the memory allocated to it, so for now, we just // want something in the tree that isn't a NULL pointer. // return adaptor->createTypeText(adaptor, ANTLR3_TOKEN_INVALID, (pANTLR3_UINT8)"Tree Error Node"); } Am I out of luck here and only the error nodes the Java target produces would allow me to retrieve the text of the erroneous nodes?

  • acts_as_solr isn't updating associated models in Rails

    - by Trey Bean
    I'm using acts_as_solr for searching in a project. Unfortunately, the index doesn't seem to be updated for the associated models when a model is saved. Example: I have three models: class Merchant < ActiveRecord::Base acts_as_solr :fields => [:name, :domain, :description], :include => [:coupons, :tags] ... end class Coupon < ActiveRecord::Base acts_as_solr :fields => [:store_name, :url, :code, :description] ... end class Tag < ActiveRecord::Base acts_as_solr :fields => [:name] ... end I use the following line to perform a search: Merchant.paginate_by_solr(params[:q], :per_page => PER_PAGE, :page => [(params[:page] || 1).to_i, 1].max) For some reason though, after I add a coupon that contains the word 'shoes' in the description, a query for 'shoes' doesn't return the merchant associated with the coupon. The association all work and if I run rake solr:reindex, the search then returns the new coupon. Do I need to update the index for Merchant each time a new coupon is created? Do I have to update the index for the whole class or can I just update the associated merchant? Shouldn't this be done automatically? Thanks for any input.

  • How do i convert String to Integer/Float in Haskell

    - by Ranhiru
    data GroceryItem = CartItem ItemName Price Quantity | StockItem ItemName Price Quantity makeGroceryItem :: String -> Float -> Int -> GroceryItem makeGroceryItem name price quantity = CartItem name price quantity I want to create a GroceryItem when using a String or [String] createGroceryItem :: [String] -> GroceryItem createGroceryItem (a:b:c) = makeGroceryItem a b c The input will be in the format ["Apple","15.00","5"] which i broke up using words function in haskell. I get this error which i think is because the makeGroceryItem accepts a Float and an Int. But how do i make b and c Float and Int respectively? *Type error in application *** Expression : makeGroceryItem a read b read c *** Term : makeGroceryItem *** Type : String -> Float -> Int -> GroceryItem *** Does not match : a -> b -> c -> d -> e -> f* Thanx a lot in advance :)

  • Finding min and max values

    - by user01
    I am trying to write a simple program that reads integers from a data file and outputs the minimum and maximum value. The first integer of the input file will indicate how many more integers will be read, and then the integers will be listed. My program compiles without any problem, however, it returns values that are not part of the set in my test data file. Could anyone help with diagnose this issue? int main(){ FILE *fp = fopen("data.txt", "r"); int count; int num; int i; int min = 0; int max = 0; fscanf (fp, "%d", &count); for (i = 0; i < count; i++) fscanf( fp, "%d", &i); { if (num < min) min = num; if (num > max) max = num; } fclose (fp); printf("Of the %d integers, the minimum value is %d and the maximum value is %d \n", count, min, max);}

  • Jquery star rating plugin and cancel rating button

    - by Roger
    Using this plugin: http://www.fyneworks.com/jquery/star-rating/#tab-Testing I have a simple callback function that picks up the id from the radio buttons: <input type="radio" class="auto-submit-star {split:2}" id="myid" value="1" /> $('.auto-submit-star').rating({ callback: function(value, link){ alert($(this).attr('id')); } }); This works fine, but if the user clicks on the cancel button, then it can't read the id of it. In the js, I think the cancel button is added dynamically with: control.cancel = $('<div class="rating-cancel"><a title="' + control.cancel + '">' + control.cancelValue + '</a></div>') If I add an id to it like this: control.cancel = $('<div class="rating-cancel"><a id="someid" title="' + control.cancel + '">' + control.cancelValue + '</a></div>') How could I read the id? This would be undefined. I can set a class and use $('.myclass').attr('id') but I will have multiple ratings on one page so I'll need something similar to "this". Or is it possible for the cancel button to pick up the id of the corresponding radio buttons?

  • C# COM objects with VB6/asp error

    - by Ken
    I'm trying to expose a C# class library via COM so that I can use it in a classic asp web site. I've used sn - k, regasm and gacutil. About all I can do now though is echo back strings. Methods which take Class variables as input are not working for me. ie my test method EchoPerson(Person p) which returns a string of the first and last name doesn't work. I get a runtime error 5 - Invalid procedure call or argument. Please let me know what I am missing. Also I have no intellisence in VB. What do I need to do to get the intellisence working. Below is my C# test code namespace MrdcToFastCom { public class Person : MrdcToFastCom.IPerson { public string FirstName { get; set; } public string LastName { get; set; } } public class ComTester : MrdcToFastCom.IComTester { public string EchoString(string s) { return ("Echo: " + s); } public string Hello() { return "Hello"; } public string EchoPerson(ref Person p) { return string.Format("{0} {1}", p.FirstName, p.LastName); } } } and VB6 call Private Sub btnClickMe_Click() Dim ct Set ct = New MrdcToFastCom.ComTester Dim p Set p = New MrdcToFastCom.Person p.FirstName = "Joe" p.LastName = "Test" Dim s s = ct.EchoPerson(p) 'Error on this line tbx1.Text = s End Sub
