• Passing dynamic parameter to a JavaScript function using innerHTML

  - by user958263

  I am having issues passing a dynamic parameter to a JavaScript function using innerHTML. Included below is the current code that I am using: var name = "test"; frm.innerHtml = '<button name="close" id="close" title="Cancel" type="button" onclick="closeTab('+name+');">Return</button>'; When I debug the code of the CloseTab() function, the parameter specified by the name variable is null. I believe there is a problem with the declaration of the value while modifying the innerHTML property. Any help would be greatly appreciated. Thanks

• Trouble passing a template function as an argument to another function in C++

  - by Darel

  Source of the problem -Accelerated C++, problem 8-5 I've written a small program that examines lines of string input, and tallies the number of times a word appears on a given line. The following code accomplishes this: #include <map> #include <iostream> #include <string> #include <vector> #include <list> #include <cctype> #include <iterator> using std::vector; using std::string; using std::cin; using std::cout; using std::endl; using std::getline; using std::istream; using std::string; using std::list; using std::map; using std::isspace; using std::ostream_iterator; using std::allocator; inline void keep_window_open() { cin.clear(); cout << "Please enter EOF to exit\n"; char ch; cin >> ch; return; } template <class Out> void split(const string& s, Out os) { vector<string> ret; typedef string::size_type string_size; string_size i = 0; // invariant: we have processed characters `['original value of `i', `i)' while (i != s.size()) { // ignore leading blanks // invariant: characters in range `['original `i', current `i)' are all spaces while (i != s.size() && isspace(s[i])) ++i; // find end of next word string_size j = i; // invariant: none of the characters in range `['original `j', current `j)' is a space while (j != s.size() && !isspace(s[j])) ++j; // if we found some nonwhitespace characters if (i != j) { // copy from `s' starting at `i' and taking `j' `\-' `i' chars *os++ = (s.substr(i, j - i)); i = j; } } } // find all the lines that refer to each word in the input map<string, vector<int> > xref(istream& in) // works // now try to pass the template function as an argument to function - what do i put for templated type? //map<string, vector<int> > xref(istream& in, void find_words(vector<string, typedef Out) = split) #LINE 1# { string line; int line_number = 0; map<string, vector<int> > ret; // read the next line while (getline(in, line)) { ++line_number; // break the input line into words vector<string> words; // works // #LINE 2# split(line, back_inserter(words)); // #LINE 3# //find_words(line, back_inserter(words)); // #LINE 4# attempting to use find_words as an argument to function // remember that each word occurs on the current line for (vector<string>::const_iterator it = words.begin(); it != words.end(); ++it) ret[*it].push_back(line_number); } return ret; } int main() { cout << endl << "Enter lines of text, followed by EOF (^Z):" << endl; // call `xref' using `split' by default map<string, vector<int> > ret = xref(cin); // write the results for (map<string, vector<int> >::const_iterator it = ret.begin(); it != ret.end(); ++it) { // write the word cout << it->first << " occurs on line(s): "; // followed by one or more line numbers vector<int>::const_iterator line_it = it->second.begin(); cout << *line_it; // write the first line number ++line_it; // write the rest of the line numbers, if any while (line_it != it->second.end()) { cout << ", " << *line_it; ++line_it; } // write a new line to separate each word from the next cout << endl; } keep_window_open(); return 0; } As you can see, the split function is a template function to handle various types of output iterators as desired. My problem comes when I try to generalize the xref function by passing in the templated split function as an argument. I can't seem to get the type correct. So my question is, can you pass a template function to another function as an argument, and if so, do you have to declare all types before passing it? Or can the compiler infer the types from the way the templated function is used in the body? To demonstrate the errors I get, comment out the existing xref function header, and uncomment the alternate header I'm trying to get working (just below the following commment line.) Also comment the lines tagged LINE 2 and LINE 3 and uncomment LINE 4, which is attempting to use the argument find_words (which defaults to split.) Thanks for any feedback!

• Getting a null reference exception exporting a slightly complex rdlc report to excel

  - by George Handlin

  Have an issue in exporting a slightly complex report to excel from an rdlc. Exporting a simple tabular report works fine, but getting a null reference exception with a more complex one. As is usually the case, it works on the server in the development environment, but not in the test environment. The server in the development environment has iis, sql and sql reporting services on it and test only has iis (I didn't set them up). I'm guessing there is something that gets installed with SSRS that is not installed with just the report viewer. The report has several parameters going into it and a few generic lists going in for datasources. Some tables for display as well as a list. Working with the 2005 version. Exception follows: [NullReferenceException: Object reference not set to an instance of an object.] Microsoft.ReportingServices.Rendering.ExcelRenderer.ExcelRenderer.RenderPageLayout(PageLayout pageLayout, Int32& currentPageNumber, Stack& stack) +91 Microsoft.ReportingServices.Rendering.ExcelRenderer.ExcelRenderer.RenderPageCollection(PageCollection pageCollection, Int32& currentPageNumber, Stack& stack, PageLayout& lastPageLayout) +607 Microsoft.ReportingServices.Rendering.ExcelRenderer.ExcelRenderer.GenerateWorkSheets() +150 Microsoft.ReportingServices.Rendering.ExcelRenderer.ExcelRenderer.GenerateMainSheet() +358 Microsoft.ReportingServices.Rendering.ExcelRenderer.ExcelRenderer.RenderExcelWorkBook(CreateAndRegisterStream createAndRegisterStream) +158 Microsoft.ReportingServices.Rendering.ExcelRenderer.ExcelRenderer.ProcessReport(CreateAndRegisterStream createAndRegisterStream) +385 Microsoft.ReportingServices.Rendering.ExcelRenderer.ExcelRenderer.Render(Report report, NameValueCollection reportServerParameters, NameValueCollection deviceInfo, NameValueCollection clientCapabilities, EvaluateHeaderFooterExpressions evaluateHeaderFooterExpressions, CreateAndRegisterStream createAndRegisterStream) +230 [ReportRenderingException: An error occurred during rendering of the report.] Microsoft.ReportingServices.Rendering.ExcelRenderer.ExcelRenderer.Render(Report report, NameValueCollection reportServerParameters, NameValueCollection deviceInfo, NameValueCollection clientCapabilities, EvaluateHeaderFooterExpressions evaluateHeaderFooterExpressions, CreateAndRegisterStream createAndRegisterStream) +296 Microsoft.ReportingServices.ReportProcessing.ReportProcessing.RenderSnapshot(IRenderingExtension renderer, CreateReportChunk createChunkCallback, RenderingContext rc, GetResource getResourceCallback) +1124 [WrapperReportRenderingException: An error occurred during rendering of the report.] Microsoft.ReportingServices.ReportProcessing.ReportProcessing.RenderSnapshot(IRenderingExtension renderer, CreateReportChunk createChunkCallback, RenderingContext rc, GetResource getResourceCallback) +1681 Microsoft.Reporting.LocalService.RenderWithDataCache(PreviewItemContext itemContext, ParameterInfoCollection reportParameters, IEnumerable dataSources, DatasourceCredentialsCollection credentials, IRenderingExtension renderer, ReportProcessing repProc, CreateAndRegisterStream createStreamCallback, ReportRuntimeSetup runtimeSetup) +1693 Microsoft.Reporting.LocalService.Render(PreviewItemContext itemContext, Boolean allowInternalRenderers, ParameterInfoCollection reportParameters, IEnumerable dataSources, DatasourceCredentialsCollection credentials, CreateAndRegisterStream createStreamCallback, ReportRuntimeSetup runtimeSetup, ProcessingMessageList& warnings) +227 Microsoft.Reporting.WebForms.LocalReport.InternalRender(String format, Boolean allowInternalRenderers, String deviceInfo, CreateAndRegisterStream createStreamCallback, Warning[]& warnings) +235 [LocalProcessingException: An error occurred during local report processing.] Microsoft.Reporting.WebForms.LocalReport.InternalRender(String format, Boolean allowInternalRenderers, String deviceInfo, CreateAndRegisterStream createStreamCallback, Warning[]& warnings) +276 Microsoft.Reporting.WebForms.LocalReport.InternalRender(String format, Boolean allowInternalRenderers, String deviceInfo, String& mimeType, String& encoding, String& fileNameExtension, String[]& streams, Warning[]& warnings) +189 Microsoft.Reporting.WebForms.LocalReport.Render(String format, String deviceInfo, String& mimeType, String& encoding, String& fileNameExtension, String[]& streams, Warning[]& warnings) +28 Microsoft.Reporting.WebForms.LocalReportControlSource.RenderReport(String format, String deviceInfo, NameValueCollection additionalParams, String& mimeType, String& fileNameExtension) +52 Microsoft.Reporting.WebForms.ExportOperation.PerformOperation(NameValueCollection urlQuery, HttpResponse response) +153 Microsoft.Reporting.WebForms.HttpHandler.ProcessRequest(HttpContext context) +202 System.Web.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +303 System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +64

• Can't obtain reference to EKReminder array retrieved from fetchRemindersMatchingPredicate

  - by Scionwest

  When I create an NSPredicate via EKEventStore predicateForRemindersInCalendars; and pass it to EKEventStore fetchRemindersMatchingPredicate:completion:^ I can loop through the reminders array provided by the completion code block, but when I try to store a reference to the reminders array, or create a copy of the array into a local variable or instance variable, both array's remain empty. The reminders array is never copied to them. This is the method I am using, in the method, I create a predicate, pass it to the event store and then loop through all of the reminders logging their title via NSLog. I can see the reminder titles during runtime thanks to NSLog, but the local arrayOfReminders object is empty. I also try to add each reminder into an instance variable of NSMutableArray, but once I leave the completion code block, the instance variable remains empty. Am I missing something here? Can someone please tell me why I can't grab a reference to all of the reminders for use through-out the app? I am not having any issues at all accessing and storing EKEvents, but for some reason I can't do it with EKReminders. - (void)findAllReminders { NSPredicate *predicate = [self.eventStore predicateForRemindersInCalendars:nil]; __block NSArray *arrayOfReminders = [[NSArray alloc] init]; [self.eventStore fetchRemindersMatchingPredicate:predicate completion:^(NSArray *reminders) { arrayOfReminders = [reminders copy]; //Does not work. for (EKReminder *reminder in reminders) { [self.remindersForTheDay addObject:reminder]; NSLog(@"%@", reminder.title); } }]; //Always = 0; if ([self.remindersForTheDay count]) { NSLog(@"Instance Variable has reminders!"); } //Always = 0; if ([arrayOfReminders count]) { NSLog(@"Local Variable has reminders!"); } } The eventStore getter is where I perform my instantiation and get access to the event store. - (EKEventStore *)eventStore { if (!_eventStore) { _eventStore = [[EKEventStore alloc] init]; //respondsToSelector indicates iOS 6 support. if ([_eventStore respondsToSelector:@selector(requestAccessToEntityType:completion:)]) { //Request access to user calendar [_eventStore requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) { if (granted) { NSLog(@"iOS 6+ Access to EventStore calendar granted."); } else { NSLog(@"Access to EventStore calendar denied."); } }]; //Request access to user Reminders [_eventStore requestAccessToEntityType:EKEntityTypeReminder completion:^(BOOL granted, NSError *error) { if (granted) { NSLog(@"iOS 6+ Access to EventStore Reminders granted."); } else { NSLog(@"Access to EventStore Reminders denied."); } }]; } else { //iOS 5.x and lower support if Selector is not supported NSLog(@"iOS 5.x < Access to EventStore calendar granted."); } for (EKCalendar *cal in self.calendars) { NSLog(@"Calendar found: %@", cal.title); } [_eventStore reset]; } return _eventStore; } Lastly, just to show that I am initializing my remindersForTheDay instance variable using lazy instantiation. - (NSMutableArray *)remindersForTheDay { if (!_remindersForTheDay) _remindersForTheDay = [[NSMutableArray alloc] init]; return _remindersForTheDay; } I've read through the Apple documentation and it doesn't provide any explanation that I can find to answer this. I read through the Blocks Programming docs and it states that you can access local and instance variables without issues from within a block, but for some reason, the above code does not work. Any help would be greatly appreciated, I've scoured Google for answers but have yet to get this figured out. Thanks everyone! Johnathon.

• Passing a list of files to javac

  - by Robert Menteer

  How can I get the javac task to use an existing fileset? In my build.xml I have created several filesets to be used in multiple places throughout build file. Here is how they have been defined: <fileset dir = "${src}" id = "java.source.all"> <include name = "**/*.java" /> </fileset> <fileset dir = "${src}" id = "java.source.examples"> <include name = "**/Examples/**/*.java" /> </fileset> <fileset dir = "${src}" id = "java.source.tests"> <include name = "**/Tests/*.java" /> </fileset> <fileset dir = "${src}" id = "java.source.project"> <include name = "**/*.java" /> <exclude name = "**/Examples/**/*.java" /> <exclude name = "**/Tests/**/*.java" /> </fileset> I have also used macrodef to compile the java files so the javac task does not need to be repeated multiple times. The macro looks like this: <macrodef name="compile"> <attribute name="sourceref"/> <sequential> <javac srcdir = "${src}" destdir = "${build}" classpathref = "classpath" includeantruntime = "no" debug = "${debug}"> <filelist dir="." files="@{sourceref}" /> <-- email is about this </javac> </sequential> What I'm trying to do is compile only the classes that are needed for specific targets not all the targets in the source tree. And do so without having to specify the files every time. Here are how the targets are defined: <target name = "compile-examples" depends = "init"> <compile sourceref = "${toString:java.source.examples}" /> </target> <target name = "compile-project" depends = "init"> <compile sourceref = "${toString:java.source.project}" /> </target> <target name = "compile-tests" depends = "init"> <compile sourceref = "${toString:java.source.tests}" /> </target> As you can see each target specifies the java files to be compiled as a simi-colon separated list of absolute file names. The only problem with this is that javac does not support filelist. It also does not support fileset, path or pathset. I've tried using but it treats the list as a single file name. Another thing I tried is sending the reference directly (not using toString) and using but include does not have a ref attribute. SO THE QUESTION IS: How do you get the javac task to use a reference to a fileset that was defined in another part of the build file? I'm not interested in solutions that cause me to have multiple javac tasks. Completely re-writting the macro is acceptable. Changes to the targets are also acceptable provided redundant code between targets is kept to a minimum. p.s. Another problem is that fileset wants a comma separated list. I've only done a brief search for a way to convert semi-colons to commas and haven't found a way to do that. p.p.s. Sorry for the yelling but some people are too quick to post responses that don't address the subject.

• cannot convert 'b2PolygonShape' to 'objc_object*' in argument passing

  - by GONeale

  Hey there, I am not sure if many of you are familiar with the box2d physics engine, but I am using it within cocos2d and objective c. This more or less could be a general objective-c question though, I am performing this: NSMutableArray *allShapes = [[NSMutableArray array] retain]; b2PolygonShape shape; .. .. [allShapes addObject:shape]; and receiving this error on the addObject definition on build: cannot convert 'b2PolygonShape' to 'objc_object*' in argument passing So more or less I guess I want to know how to add a b2PolygonShape to a mutable array. b2PolygonShape appears to just be a class, not a struct or anything like that. The closest thing I could find on google to which I think could do this is described as 'encapsulating the b2PolygonShape as an NSObject and then add that to the array', but not sure the best way to do this, however I would have thought this object should add using addObject, as some of my other instantiated class objects add to arrays fine. Is this all because b2PolygonShape does not inherit NSObject at it's root? Thanks

• Uploadify: Passing a form's ID as a parameter with scriptData

  - by Matt

  I need the ability to have multiple upload inputs on one page (potentially hundreds) using Uploadify. The upload PHP file will be renaming the uploaded file based on the ID of the input button used to submit it, so it will need that ID. Since I will be having hundreds of upload buttons on one page, I wanted to create a universal instantiation, so I did this using the class of the forms rather than the ID of the forms. However, when one of the inputs is clicked, I would like to pass the ID of that input as scriptData to the PHP. This is not working; PHP says 'formId' is undefined. Is there a good way get the ID attribute of the form input being used, and passing it to the upload PHP? Or is there a completely different and better method of accomplishing this? Thank you in advance!! <script type="text/javascript"> $(document).ready(function() { $('.uploady').uploadify({ 'uploader' : '/uploadify/uploadify.swf', 'script' : '/uploadify/uploadify.php', 'cancelImg' : '/uploadify/cancel.png', 'folder' : '/uploadify', 'auto' : true, // LINE IN QUESTION 'scriptData' : {'formId':$(this).attr('id')} }); }); </script> </head> The inputs look like this: <input id="file_upload1" class="uploady" name="file_upload" type="file" /> <input id="file_upload2" class="uploady" name="file_upload" type="file" /> <input id="file_upload3" class="uploady" name="file_upload" type="file" />

• Partial specialization with reference template parameter fails to compile in VS2005

  - by Blair Holloway

  I have code that boils down to the following: template struct Foo {}; template & I struct FooBar {}; //////// template struct Baz {}; template & I struct Baz< FooBar { static void func(FooBar& value); }; //////// struct MyStruct { static const Foo s_floatFoo; }; // Elsewhere: const Foo MyStruct::s_floatFoo; void callBaz() { typedef FooBar FloatFooBar; FloatFooBar myFloatFooBar; Baz::func(myFloatFooBar); } This compiles successfully under GCC, however, under VS2005, I get: error C2039: 'func' : is not a member of 'Baz' with [ T=FloatFooBar ] error C3861: 'func': identifier not found However, if I change const Foo<T>& I to const Foo<T>* I (passing I by pointer rather than by reference), and defining FloatFooBar as: typedef FooBar FloatFooBar; Both GCC and VS2005 are happy. What's going on? Is this some kind of subtle template substitution failure that VS2005 is handling differently to GCC, or a compiler bug? (The strangest thing: I thought I had the above code working in VS2005 earlier this morning. But that was before my morning coffee. I'm now not entirely certain I wasn't under some sort of caffeine-craving-induced delirium...)

• DataContract Known Types - passing array

  - by Erup

  Im having problems when passing an generic List, trough a WCF operation. In this case, there is a List of int. The example 4 is described here in MSDN. Note that in MSDN sample, is described: // This will serialize and deserialize successfully because the generic List is equivalent to int[], which was added to known types. Above, is the DataContract: [DataContract] [KnownType(typeof(int[]))] [KnownType(typeof(object[]))] public class AccountData { [DataMember] public object accNumber1; [DataMember] public object accNumber2; [DataMember] public object accNumber3; [DataMember] public object accNumber4; } In client side, Im calling the operation like this: DataTransfer.Service.AccountData data = new DataTransfer.Service.AccountData() { accNumber1 = 100, accNumber2 = new int[100], accNumber3 = new List<int>(), accNumber4 = new ArrayList() }; cService.AddAccounts(data); Also, here is the decorations of the generated AccountData obj (WCF proxy): [System.Diagnostics.DebuggerStepThroughAttribute()] [System.CodeDom.Compiler.GeneratedCodeAttribute("System.Runtime.Serialization", "3.0.0.0")] [System.Runtime.Serialization.DataContractAttribute(Name="AccountData", Namespace="http://schemas.datacontract.org/2004/07/DataTransfer.Service")] [System.SerializableAttribute()] [System.Runtime.Serialization.KnownTypeAttribute(typeof(DataTransfer.Client.CustomerServiceReference.PurchaseOrder))] [System.Runtime.Serialization.KnownTypeAttribute(typeof(DataTransfer.Client.CustomerServiceReference.Customer))] [System.Runtime.Serialization.KnownTypeAttribute(typeof(int[]))] [System.Runtime.Serialization.KnownTypeAttribute(typeof(object[]))]

• Reference a Map by name within Velocity Template

  - by Wiretap

  Pretty sure there is an easy answer to this, but just can't find the right VTL syntax. In my context I'm passing a Map which contains other Maps. I'd like to reference these inner maps by name and assign them within my template. The inner maps are constructed by different parts of the app, and then added to the context by way of example public static void main( String[] args ) throws Exception { VelocityEngine ve = new VelocityEngine(); ve.init(); Template t = ve.getTemplate( "test.vm" ); VelocityContext context = new VelocityContext(); Map<String,Map<String,String>> messageData = new HashMap<String, Map<String,String>>(); Map<String,String> data_map = new HashMap<String,String>(); data_map.put("data_1","1234"); data_map.put("a_date", "31-Dec-2009"); messageData.put("inner_map", data_map); context.put("msgData", messageData); StringWriter writer = new StringWriter(); t.merge( context, writer ); System.out.println( writer.toString() ); } Template - test.vm #set ($in_map = $msgData.get($inner_map) ) data: $in_map.data_1 $in_map.a_date

• Passing a LINQ DataRow Reference in a GridView's ItemTemplate

  - by Bob Kaufman

  Given the following GridView: <asp:GridView runat="server" ID="GridView1" AutoGenerateColumns="false" DataKeyNames="UniqueID" OnSelectedIndexChanging="GridView1_SelectedIndexChanging" > <Columns> <asp:BoundField HeaderText="Remarks" DataField="Remarks" /> <asp:TemplateField HeaderText="Listing"> <ItemTemplate> <%# ShowListingTitle( ( ( System.Data.DataRowView ) ( Container.DataItem ) ).Row ) %> </ItemTemplate> </asp:TemplateField> <asp:BoundField HeaderText="Amount" DataField="Amount" DataFormatString="{0:C}" /> </Columns> </asp:GridView> which refers to the following code-behind method: protected String ShowListingTitle( DataRow row ) { Listing listing = ( Listing ) row; return NicelyFormattedString( listing.field1, listing.field2, ... ); } The cast from DataRow to Listing is failing (cannot convert from DataRow to Listing) I'm certain the problem lies in what I'm passing from within the ItemTemplate, which is simply not the right reference to the current record from the LINQ to SQL data set that I've created, which looks like this: private void PopulateGrid() { using ( MyDataContext context = new MyDataContext() ) { IQueryable < Listing > listings = from l in context.Listings where l.AccountID == myAccountID select l; GridView1.DataSource = listings; GridView1.DataBind(); } }

• Simple .HTACCESS Passing Variables

  - by Willie Murray III

  Let's says I have a classifieds site which has a URL structure similar to the one which I have listed below: Ex. http://takarat.com/openclassifieds/?category=iphone&location=tennessee This is what shows up when I click "tennessee" as the location and then click on "iphone" as the category. Now let's say this site has a search box and I wanted a URL which comes up after using this search box to show up as opposed to the previous URL. Let's say that whenever I search for the word "iphone" while WITHIN the iphone CATEGORY the following link shows up: Iphone SEARCH Ex. http://takarat.com/openclassifieds/?s=iphone&category=iphone&location=tennessee Ok, I want THAT iphone SEARCH to come up whenever anyone clicks Tennessee Iphone..How would I do this [by the way, I want this to be dynamic so that I can use the code for different combinations of locations and products etc..I want the code to use the CATEGORY name to conduct the search basically]? I believe that this will involve "Passing varibles" from the original link... I am new to programming so I may have my terminology wrong. Any help would be appreciated. Thanks in advance.

• Passing row from UIPickerView to integer CoreData attribute

  - by Gordon Fontenot

  I'm missing something here, and feeling like an idiot about it. I'm using a UIPickerView in my app, and I need to assign the row number to a 32-bit integer attribute for a Core Data object. To do this, I am using this method: -(void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component { object.integerValue = row; } This is giving me a warning: warning: passing argument 1 of 'setIntegerValue:' makes pointer from integer without a cast What am I mixing up here? --EDIT 1-- Ok, so I can get rid of the errors by changing the method to do the following: NSNumber *number = [NSNumber numberWithInteger:row]; object.integerValue = rating; However, I still get a value of 0 for object.integerValue if I use NSLog to print it out. object.integerValue has a max value of 5, so I print out number instead, and then I'm getting a number above 62,000,000. Which doesn't seem right to me, since there are 5 rows. If I NSLog the row variable, I get a number between 0 and 5. So why do I end up with a completely different number after casting the number to NSNumber?

• Passing an instance variable through RJS?

  - by Elliot

  Hey guys here is my code (roughly): books.html.erb <% @books.each do |book| %> <% @bookid = book.id %> <div id="enter_stuff"> <%= render "input", :bookid => @bookid %> </div> <%end%> _input.html.erb <% @book = Book.find_by_id(@bookid) %> <strong>your book is: <%=h @book.name %></strong> create.rjs page.replace_html :enter_stuff, :partial => 'input', :object => @bookid The problem here is that only create.js doesn't seem to work (though, if instead of passing the partial I passed "..." it does work, so I know its that there are instance variables in the partial that aren't being reset. Any ideas?) So the final question, is how do I pass an instance variable to a partial through the create.rjs file? p.s. I know I will have duplicate div IDs, I'm not worrying about that for now though. Best, Elliot

• Passing Key-Value pair to a COM method in C#

  - by Sinnerman

  Hello, I have the following problem: I have a project in C# .Net where I use a third party COM component. So the problem is that the above component has a method, which takes a string and a number of key-value pairs as arguments. I already managed to call that method through JavaScript like that: var srcName srcName = top.cadView.addSource( 'Database', { driver : 'Oracle', host : '10.10.1.123', port : 1234, database : 'someSID', user : 'someuser', password : 'somepass' } ) if ( srcName != '' ) { ... } ... and it worked perfectly well. However I have no idea how to do the same using C#. I tried passing the pairs as Dictionary and Struct/Class but it throws me a "Specified cast is not valid." exception. I also tried using Hashtable like that: Hashtable args = new Hashtable(); args.Add("driver", "Oracle"); args.Add("host", "10.10.1.123"); args.Add("port", 1234); args.Add("database", "someSID"); args.Add("user", "someUser"); args.Add("password", "samePass"); String srcName = axCVCanvas.addSource("Database", args); and although it doesn't throw an exception it still won't do the job, writing me in a log file [ Error] [14:38:33.281] Cad::SourceDB::SourceDB(): missing parameter 'driver' Any help will be appreciated, thanks.

• Passing arguments to commandline with directories having spaces

  - by superstar

  Hi guys, I am making a system call from perl for ContentCheck.pl and passing parameters with directories (having spaces). So I pass them in quotes, but they are not being picked up in the ContentCheck.pl file Random.pm my $call = "$perlExe $contentcheck -t $target_path -b $base_path -o $output_path -s $size_threshold"; print "\ncall: ".$call."\n"; system($call); Contentcheck.pl use vars qw($opt_t $opt_b $opt_o $opt_n $opt_s $opt_h); # initialize getopts('t:b:o:n:s:h') or do{ print "*** Error: Invalid command line option. Use option -h for help.\a\n"; exit 1}; if ($opt_h) {print $UsagePage; exit; } my $tar; if ($opt_t) {$tar=$opt_t; print "\ntarget ".$tar."\n";} else { print " in target"; print "*** Error: Invalid command line option. Use option -h for help.\a\n"; exit 1;} my $base; if ($opt_b) {$base=$opt_b;} else { print "\nin base\n"; print "*** Error: Invalid command line option.

• Passing Object to Service in WCF

  - by hgulyan

  Hi, I have my custom class Customer with its properties. I added DataContract mark above the class and DataMember to properties and it was working fine, but I'm calling a service class's function, passing customer instance as parameter and some of my properties get 0 values. While debugging I can see my properties values and after it gets to the function, some properties' values are 0. Why it can be so? There's no code between this two actions. DataContract mark workes fine, everything's ok. Any suggestions on this issue? I tried to change ByRef to ByVal, but it doesn't change anything. Why it would pass other values right and some of integer types just 0? Maybe the answer is simple, but I can't figure it out. Thank You. <DataContract()> Public Class Customer Private Type_of_clientField As Integer = -1 <DataMember(Order:=1)> Public Property type_of_client() As Integer Get Return Type_of_clientField End Get Set(ByVal value As Integer) Type_of_clientField = value End Set End Property End Class <ServiceContract(SessionMode:=SessionMode.Allowed)> <DataContractFormat()> Public Interface CustomerService <OperationContract()> Function addCustomer(ByRef customer As Customer) As Long End Interface type_of_client properties value is 6 before I call addCustomer function. After it enters that function the value is 0. UPDATE: The issue is in instance creating. When I create an instance of a class on client side, that is stored on service side, some of my properties pass 0 or nothing, but when I call a function of a service class, that returns a new instance of that class, it works fine. What's is the difference? Could that be serialization issue?

• Passing a URL as a URL parameter

  - by Andrea

  I am implementing OpenId login in a CakePHP application. At a certain point, I need to redirect to another action, while preserving the information about the OpenId identity, which is itself a URL (with GET parameters), for instance https://www.google.com/accounts/o8/id?id=31g2iy321i3y1idh43q7tyYgdsjhd863Es How do I pass this data? The first attempt would be function openid() { ... $this->redirect(array('controller' => 'users', 'action' => 'openid_create', $openid)); } but the obvious problem is that this completely messes up the way CakePHP parses URL parameters. I'd need to do either of the following: 1) encode the URL in a CakePHP friendly manner for passing it, and decoding it after that, or 2) pass the URL as a POST parameter but I don't know how to do this. EDIT: In response to comments, I should be more clear. I am using the OpenId component, and I have a working OpenId implementation. What I need to do is to link OpenId with an existing user system. When a new user logs in via OpenId, I ask for more details, and then create a new user with this data. The problem is that I have to keep the OpenId URL throughout this process.

• Passing array values in an HTTP request in .NET

  - by Zarjay

  What's the standard way of passing and processing an array in an HTTP request in .NET? I have a solution, but I don't know if it's the best approach. Here's my solution: <form action="myhandler.ashx" method="post"> <input type="checkbox" name="user" value="Aaron" /> <input type="checkbox" name="user" value="Bobby" /> <input type="checkbox" name="user" value="Jimmy" /> <input type="checkbox" name="user" value="Kelly" /> <input type="checkbox" name="user" value="Simon" /> <input type="checkbox" name="user" value="TJ" /> <input type="submit" value="Submit" /> </form> The ASHX handler receives the "user" parameter as a comma-delimited string. You can get the values easily by splitting the string: public void ProcessRequest(HttpContext context) { string[] users = context.Request.Form["user"].Split(','); } So, I already have an answer to my problem: assign multiple values to the same parameter name, assume the ASHX handler receives it as a comma-delimited string, and split the string. My question is whether or not this is how it's typically done in .NET. What's the standard practice for this? Is there a simpler way to grab the multiple values than assuming that the value is comma-delimited and calling Split() on it? Is this how arrays are typically passed in .NET, or is XML used instead? Does anyone have any insight on whether or not this is the best approach?

• Passing variables to a Custom Zend Form Element

  - by user322003

  Hi, I'm trying to create a custom form element which extends Zend_Form_Element_Text with a validator (so I don't have to keep setting up the validator when I use certain elements). Anyway, I'm having trouble passing $maxChars variable to it when I instantiate it in my Main form. I've provided my shortened code below This is my custom element below class My_Form_Custom_Element extends Zend_Form_Element_Text { public $maxChars public function init() { $this->addValidator('StringLength', true, array(0, $this->maxChars)) } public function setProperties($maxChars) { $this->maxChars= $maxChars; } } This is where I instantiate my custom form element. class My_Form_Abc extends Zend_Form { public function __construct($options = null) { parent::__construct($options); $this->setName('abc'); $customElement = new My_Form_Custom_Element('myCustomElement'); $customElement->setProperties(100); //**<----This is where i set the $maxChars** $submit = new Zend_Form_Element_Submit('submit'); $submit -> setAttrib('id', 'submitbutton'); $this->addElements(array($customElement ,$submit)); } } When I try to pass '100' using $customElement-setProperties(100) in my Form, it doesnt get passed properly to my StringLength validator. I assume it's because the validator is getting called in Init? How can I fix this?

• Passing ByteArray from flash (as3) to AMFPHP (2.0.1)

  - by Mauro

  i have a problem passing ByteArray from flash (as3) to amfphp to save an image. With old version of amfphp, all worked in the past… now, with new version i have many problem. I'm using version 2.0.1 and the first problem is that i have to do this, for access to my info: function SaveAsJPEG($json) { $string = json_encode($json); $obj = json_decode($string); $compressed = $obj->{'compressed'}; } in the past i wrote only: function SaveAsJPEG($json) { $compressed = $json['compressed']; } Anyway… now i can take all data (if i use " $json['compressed']" i receive an error) but i can't receive my ByteArray data. From flash i write this: var tempObj:Object = new Object(); tempObj["jpgStream "]= createBitStream(myBitmmapData); // return ByteArray tempObj["compressed"] = false; tempObj["dir"] = linkToSave; tempObj["name"] = this.imageName; So.. in my php class i receive all correct info, except "jpgStream" that seems "null". Do you have any idea?

• Error when passing quotes to webservice by AJAX

  - by Radu

  I'm passing data using .ajax and here are my data and contentType attributes: data: '{ "UserInput" : "' + $('#txtInput').val() + '","Options" : { "Foo1":' + bar1 + ', "Foo2":' + Bar2 + ', "Flags":"' + flags + '", "Immunity":' + immunity + '}}', contentType: 'application/json; charset=utf-8', Server side my code looks like this: <WebMethod()> _ Public Shared Function ParseData(ByVal UserInput As String, ByVal Options As Options) As String The userinput is obvious but the Options structure is like the following: Public Structure Options Dim Foo1 As Boolean Dim Foo2 As Boolean Dim Flags As String Dim Immunity As Integer End Structure Everything works fine when $('#txtInput') contains no double-quotes but if they are present I get an error (for an input of asd"): {"Message":"Invalid object passed in, \u0027:\u0027 or \u0027}\u0027 expected.

Also, when I pass the same input with quotes directly it works fine.

• Passing a parameter in a Report's Open Event to a parameter query (Access 2007)

  - by JPM

  Hi there, I would like to know if there is a way to set the parameters in an Access 2007 query using VBA. I am new to using VBA in Access, and I have been tasked with adding a little piece of functionality to an existing app. The issue I am having is that the same report can be called in two different places in the application. The first being on a command button on a data entry form, the other from a switchboard button. The report itself is based on a parameter query that has requires the user to enter a Supplier ID. The user would like to not have to enter the Supplier ID on the data entry form (since the form displays the Supplier ID already), but from the switchboard, they would like to be prompted to enter a Supplier ID. Where I am stuck is how to call the report's query (in the report's open event) and pass the SupplierID from the form as the parameter. I have been trying for a while, and I can't get anything to work correctly. Here is my code so far, but I am obviously stumped. Private Sub Report_Open(Cancel As Integer) Dim intSupplierCode As Integer 'Check to see if the data entry form is open If CurrentProject.AllForms("frmExample").IsLoaded = True Then 'Retrieve the SupplierID from the data entry form intSupplierCode = Forms![frmExample]![SupplierID] 'Call the parameter query passing the SupplierID???? DoCmd.OpenQuery "qryParams" Else 'Execute the parameter query as normal DoCmd.OpenQuery "qryParams"????? End If End Sub I've tried Me.SupplierID = intSupplierCode, and although it compiles, it bombs when I run it. And here is my SQL code for the parameter query: PARAMETERS [Enter Supplier] Long; SELECT Suppliers.SupplierID, Suppliers.CompanyName, Suppliers.ContactName, Suppliers.ContactTitle FROM Suppliers WHERE (((Suppliers.SupplierID)=[Enter Supplier])); I know there are ways around this problem (and probably an easy way as well) but like I said, my lack of experience using Access and VBA makes things difficult. If any of you could help, that would be great!
