  • SSRS & asp.net - passing parameters from .net to ssrs in report viewer

    - by Ricardo Deano
    Hello all. I am about to embark in using a report viewer in my .net page. I have a page that will search for a catgory, upon a button click, the category chosen will pass into the parameter of report viewer. Now, given that I am a newbie to both SSRS and .net, I'd just like a bit of advice on how to tackle this. Should I make the report in SSRS first and include the parameters in this report or can I make the report without the parameters specified, then programmatically enter this in the codebehind? Basically, I know what I would like to do but not sure the best approach to take. If anyone can offer advice, I would be most grateful.

  • JQGrid tree - passing additional parameters when tree is expanded

    - by PHP thinker
    I have a JQGRid tree. It loads data click by click, not all at once. Typically, JQGRid passes 4 standard tree parameters with each call - row (level, parent, is leaf, is expanded). How can I pass more parameters that I will take from the row being expanded? E.g. data from Name column should be passed in AJAX call too. There doesn't seem to be OnExpand event or similar.

  • DirectShow - passing parameters to custom source push filter

    - by mkurek
    Hello, I'm working on a solution that will be used to receive video stream from remote hosts and to put various texts on the top of it. Currently it consists of custom DirectShow push filter (C++) which receives data from remote hosts using RTP protocol and tiny C# application that sets up the DirectShow graph and is used as a container for the video. I'm using DirectShowLib interop library. However, I'm not sure how to pass parameters from this C# app to my custom filter. What are possible ways to do it?

  • Reporting Services 2010 RDLC: Passing Querystring Parameters from an RDLC

    - by Brian MacKay
    I'm trying to build a simple RDLC report that shows some data, and has a 'select' link that sends the browser off to a certain url with some data in the querystring (a key). In the vs2010 report designer, I can double-click on the column, then select action, and there are a bunch of thigns that seem like they might work. But none of them do. Under 'enable as a hyperlink' I can pick 'go to url' but there aren't any parameter options to pass. I also tried 'go to report' on the off chance that I could trick it into doing what I want. Here there are parameter options, but it knows that my url is not a report and the "select" link renders as text (not clickable). Any ideas? I'm pretty sure this used to work in vs2008, and it seems like something that must be doable. But I've been pulling out my hair for several hours on this one.

  • Passing List of Strings or Array of strings into Unity Injection Constructor (Config-Based)

    - by miguel
    I cannot seem to get unity working when attempting to pass in an array of strings into a constructor parameter list, while using XML configuration. When I try the following: <typeConfig ...> <constructor ...> <param ... parameterType="System.String[]"> <array> <value.../> <value.../> </array> </param> </constructor> </typeConfig> for a c'tor which looks like this: void Foo(string[] inputParams_){ ... } It always fails in Unity's FindConstructor(...) method stating that it cannot find a c'tor mathcing the parameter type of String.String Does anyone know how to pass an array of stings successfully into this type of c'tor? If not, how can I do so with a list of strings, if the c'tor were to accept an IList? Thanks!

  • C++ template-function -> passing a template-class as template-argument

    - by SeMa
    Hello, i try to make intensive use of templates to wrap a factory class: The wrapping class (i.e. classA) gets the wrapped class (i.e. classB) via an template-argument to provide 'pluggability'. Additionally i have to provide an inner-class (innerA) that inherits from the wrapped inner-class (innerB). The problem is the following error-message of the g++ "gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5)": sebastian@tecuhtli:~/Development/cppExercises/functionTemplate$ g++ -o test test.cpp test.cpp: In static member function ‘static classA<A>::innerA<iB>* classA<A>::createInnerAs(iB&) [with iB = int, A = classB]’: test.cpp:39: instantiated from here test.cpp:32: error: dependent-name ‘classA::innerA<>’ is parsed as a non-type, but instantiation yields a type test.cpp:32: note: say ‘typename classA::innerA<>’ if a type is meant As you can see in the definition of method createInnerBs, i intend to pass a non-type argument. So the use of typename is wrong! The code of test.cpp is below: class classB{ public: template < class iB> class innerB{ iB& ib; innerB(iB& b) :ib(b){} }; template<template <class> class classShell, class iB> static classShell<iB>* createInnerBs(iB& b){ // this function creates instances of innerB and its subclasses, // because B holds a certain allocator return new classShell<iB>(b); } }; template<class A> class classA{ // intention of this class is meant to be a pluggable interface // using templates for compile-time checking public: template <class iB> class innerA: A::template innerB<iB>{ innerA(iB& b) :A::template innerB<iB>(b){} }; template<class iB> static inline innerA<iB>* createInnerAs(iB& b){ return A::createInnerBs<classA<A>::template innerA<> >(b); // line 32: error occurs here } }; typedef classA<classB> usable; int main (int argc, char* argv[]){ int a = 5; usable::innerA<int>* myVar = usable::createInnerAs(a); return 0; } Please help me, i have been faced to this problem for several days. Is it just impossible, what i'm trying to do? Or did i forgot something? Thanks, Sebastian

  • MVCContrib ActionFilter PassParametersDuringRedirect still passes reference type in querystring

    - by redsquare
    I am attempting to use the PRG pattern in an asp.net mvc 2 rc application. I found that the MVCContrib project has a custom action filter that will auto persist the parameters in TempData In an action I have the following return this.RedirectToAction(c => c.Requested(accountAnalysis)); however this is adding a querystring param to the request e.g http://mysite.com/account/add?model=MyProject.Models.AccountAnalysisViewModel Can anyone explain how I can use the PassParametersDuringRedirect filter attribute from MVCContrib to not pass the ViewModel type in the querystring. I see a patch was issued to fix this however in the latest MvcContrib that supports MVC 2 RC it is commented out as follows public static RedirectToRouteResult RedirectToAction<T>(this Controller controller, Expression<Action<T>> action) where T : Controller { /*var body = action.Body as MethodCallExpression; AddParameterValuesFromExpressionToTempData(controller, body); var routeValues = Microsoft.Web.Mvc.Internal.ExpressionHelper.GetRouteValuesFromExpression(action); RemoveReferenceTypesFromRouteValues(routeValues); return new RedirectToRouteResult(routeValues);*/ return new RedirectToRouteResult<T>(action); } Any help much appreciated. Thanks

  • GCC vs Microsoft : Undefined reference to `_chkstk'?

    - by SethCoder
    I am using CodeBlocks and MinGW toolchain which is essentially GCC. I was using VStudio but I want to get away from it to do cross platform development. There seems to be some microsoft specific references in some libraries that I am linking, specifically in CXImage SDK (_chkstk). I presume the library was put together using VS. From my searches I have learned that GCC uses _alloca rather than _chkstk. I still want to use CXImage for some stuff I am doing. My question: Is there a way around this problem or am I stuck with ditching libs such as this if I want to use GCC?

  • C++ custom exceptions: run time performance and passing exceptions from C++ to C

    - by skyeagle
    I am writing a custom C++ exception class (so I can pass exceptions occuring in C++ to another language via a C API). My initial plan of attack was to proceed as follows: //C++ myClass { public: myClass(); ~myClass(); void foo() // throws myException int foo(const int i, const bool b) // throws myException } * myClassPtr; // C API #ifdef __cplusplus extern "C" { #endif myClassPtr MyClass_New(); void MyClass_Destroy(myClassPtr p); void MyClass_Foo(myClassPtr p); int MyClass_FooBar(myClassPtr p, int i, bool b); #ifdef __cplusplus }; #endif I need a way to be able to pass exceptions thrown in the C++ code to the C side. The information I want to pass to the C side is the following: (a). What (b). Where (c). Simple Stack Trace (just the sequence of error messages in order they occured, no debugging info etc) I want to modify my C API, so that the API functions take a pointer to a struct ExceptionInfo, which will contain any exception info (if an exception occured) before consuming the results of the invocation. This raises two questions: Question 1 1. Implementation of each of the C++ methods exposed in the C API needs to be enclosed in a try/catch statement. The performance implications for this seem quite serious (according to this article): "It is a mistake (with high runtime cost) to use C++ exception handling for events that occur frequently, or for events that are handled near the point of detection." At the same time, I remember reading somewhere in my C++ days, that all though exception handling is expensive, it only becmes expensive when an exception actually occurs. So, which is correct?. what to do?. Is there an alternative way that I can trap errors safely and pass the resulting error info to the C API?. Or is this a minor consideration (the article after all, is quite old, and hardware have improved a bit since then). Question 2 I wuld like to modify the exception class given in that article, so that it contains a simple stack trace, and I need some help doing that. Again, in order to make the exception class 'lightweight', I think its a good idea not to include any STL classes, like string or vector (good idea/bad idea?). Which potentially leaves me with a fixed length C string (char*) which will be stack allocated. So I can maybe just keep appending messages (delimted by a unique separator [up to maximum length of buffer])... Its been a while since I did any serious C++ coding, and I will be grateful for the help. BTW, this is what I have come up with so far (I am intentionally, not deriving from std::exception because of the performance reasons mentioned in the article, and I am instead, throwing an integral exception (based on an exception enumeration): class fast_exception { public: fast_exception(int what, char const* file=0, int line=0) : what_(what), line_(line), file_(file) {/*empty*/} int what() const { return what_; } int line() const { return line_; } char const* file() const { return file_; } private: int what_; int line_; char const[MAX_BUFFER_SIZE] file_; }

  • fortran 90 user defined type, passing by value ?

    - by user279137
    I have an issue in fortran 90. I have a user defined type and when I call one of the MPI subroutines the data looks to be passed by values (not address, as I thought it should). The output arguments aren't modified. It seems to be specific to the MPI calls I tried the same thing in a simple test, and I can change the passed in values in the calling scope. I'm not sure why this is because I thought fortran always pass by address. Any idea what could be going on? Just to be clear the commented snippet shows how the calls are made. The in the first call, c%NSubDomains, is an output argument and should be modified in the calling scope, but its not. WHen I call with an array rather than a member of user defined type it works, in the uncommented snippet. ! ! This doesn't work output values aren't modified ?? ! call MPI_Dims_create(c%NProcs,c%NDims,c%NSubDomains,iErr) nsubs(:)=0 call MPI_Dims_create(c%NProcs,c%NDims,nsubs,iErr) c%NSubDomains=nsubs Thanks

  • Passing an array argument from Excel VBA to a WCF service

    - by PrgTrdr
    I'm trying to pass an array as an argument to my WCF service. To test this using Damian's sample code, I modified GetData it to try to pass an array of ints instead of a single int as an argument: using System; using System.ServiceModel; namespace WcfService1 { [ServiceContract] public interface IService1 { [OperationContract] string GetData(int[] value); [OperationContract] object[] GetSomeObjects(); } } using System; namespace WcfService1 { public class Service1 : IService1 { public string GetData(int[] value) { return string.Format("You entered: {0}", value[0]); } public object[] GetSomeObjects() { return new object[] { "String", 123, 44.55, DateTime.Now }; } } } Excel VBA code: Dim addr As String addr = "service:mexAddress=""net.tcp://localhost:7891/Test/WcfService1/Service1/Mex""," addr = addr + "address=""net.tcp://localhost:7891/Test/WcfService1/Service1/""," addr = addr + "contract=""IService1"", contractNamespace=""http://tempuri.org/""," addr = addr + "binding=""NetTcpBinding_IService1"", bindingNamespace=""http://tempuri.org/""" Dim service1 As Object Set service1 = GetObject(addr) Dim Sectors( 0 to 2 ) as Integer Sectors(0) = 10 MsgBox service1.GetData(Sectors) This code works fine with the WCF Test Client, but when I try to use it from Excel, I have this problem. When Excel gets to the service1.GetData call, it reports the following error: Run-time error '-2147467261 (80004003)' Automation error Invalid Pointer It looks like there is some incompatibility between the interface specification and the VBA call. Have you ever tried to pass an array from VBA into WCF? Am I doing something wrong or is this not supported using the Service moniker?

  • How does GCC compile applications that reference a static library

    - by technobrat
    I've read that the gcc compiler can perform certain optimization when compiling an application that references a static library, for instance - it will "pull" in only that code from the static library that the application depends upon. This helps keep the size of the application's executable to a minimum if portions of the static library are not being used by the app. 1) Is this true? 2) How does GCC know what code from the static library the application is actually using? Does it only look t the header files that are included (directly and indirectly) in the application and then pull code accordingly? Or does it actually look at what methods from the static library are being called?

  • Extracting, then passing raw data into another class - How to avoid copying twice while maintaining

    - by Kache4
    Consider a class Book with a stl container of class Page. each Page holds a screenshot, like page10.jpg in raw vector<char> form. A Book is opened with a path to a zip, rar, or directory containing these screenshots, and uses respective methods of extracting the raw data, like ifstream inFile.read(buffer, size);, or unzReadCurrentFile(zipFile, buffer, size). It then calls the Page(const char* stream, int filesize) constructor. Right now, it's clear that the raw data is being copied twice. Once to extract to Book's local buffer and a second time in the Page ctor to the Page::vector<char>. Is there a way to maintain encapsulation while getting rid of the middleman buffer?

  • Reference from UITableViewCell to UITableView to UINavigationController

    - by Nick
    If the user taps and holds on a Foo table view cell for 2 seconds, a modal view should be shown. The modal view is also displayed when a new Foo is added to the cell. The modal view's delegate protocol is implemented by the parent UITableView subclass. My tap and hold detection code is in the Foo UITableViewCell class. I'm having difficulty referencing the parent tableview's navigation controller to display the modal view. FooModalViewController *modalController = [[FooModalViewController alloc] initWithNibName:@"FooModalViewController" bundle:nil]; FooTableViewController *tableView = (FooTableViewController *) self.superview; foo.delegate = tableView; Seems OK but I'm having problems referencing the navigation controller that contains the tableview.. The code below builds OK but throws an exception - NSOBject DoesNotRecognizeSelector. UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:modalController]; [[tableView.navigationController] presentModalViewController:navigationController animated:YES]; I think that perhaps my design is flawed..?

  • Hyper reference links in Latex document starts from the beginning of the page

    - by okhalid
    Hi, I have a latex document. I am using hyperref, makeidx and glossary packages for my document. Every thing is created fine; table of content (all references works nicely), glossary and index except that page numbers printed in the glossary and index are correct but they point to page numbers starting from the beginning of the document where initial 10 pages are in arabic numbers and then roman numbers from 1 starts. e.g. I have 10 pages for initial front matter (abstract, declaration, table of contents etc etc). After that, mainmatter begins and so does the page numbers in roman from 1. So on this page 1, I have an index entry "hello" Now in the index, it prints "hello 1" which is correct except that when one clicks on 1, then it goes to the right at the beginning of the document rather then numbered page 1. Your help would be much appreciated. Thanks, Omer

  • Passing variable to Google Charts URL

    Hi All, This is probably something really simple, however I am quite new to PHP, and havent done any HTML in years. I need to get a PHP variable filled with an array of figures into Google Charts. My code for this so far is: <img src="http://chart.apis.google.com/chart? &chs=340x175 &chd=t:<?=$filedetail[1]?> &cht=lc &chtt=Test "> However, Google reports an error, as it stops at the ?=$filedetail[1] for some reason. It doesnt seem that reading the variable is the problem, more that the API simply cant read past the start of the PHP tags. Thanks, Rob A.

  • Passing binary blob through an Android content provider

    - by velocityb0y
    I have a content provider that is custom to my set of Android applications, and one of the things it needs to expose is a small (20-30k) byte array. The uri for these blobs looks like content://my.authority/blob/# where # is the row number; the resulting cursor has the standard _id column and a data column. I'm using a MatrixCursor in the provider's query method: byte[] byteData = getMyByteData(); MatrixCursor mc = new MatrixCursor(COLUMNS); mc.addRow(new Object[] { id, byteData }); Later, in the application consuming the data, I do Cursor c = managedQuery(uri, null, null, null, null); c.moveToFirst(); byte[] data = c.getBlob(c.getColumnIndexOrThrow("data")); However, data does not contain the contents of my original byte array; rather, it contains something like "[B@435cc518", which looks more like the address of the array than the contents. I tried wrapping the byte array in an implementation of java.sql.Blob, figuring that it might be looking for that since the content provider subsystem was written to be easy to use with SQLite, but it didn't help. Has anyone gotten this to work? If the data was in the file system, there are methods in ContentProvider that I could use to provide a marshalled InputStream to the client, but the data I'm trying to send back lives as a resource in the content provider's APK.
