  • How to Print the contents of a textbox in C++/CLI?

    - by Smoka
    I'm still learning C++ coding. I'm having troubles getting say ResultsBox-Text to printer successfully. What is the proper way to print in C++/CLI? I think im missing something simple. Ive tried multiple different routes/syntax's that ive read online/ in books. All of which got me to a dead end. Please even a rundown on the method of printing in any C based language might point me the right way. Thank you.

  • Can you pass parameters for OnAction in MS Project VBA?

    - by Anne Schuessler
    The way I can define a method to be executed with OnAction in VBA with Microsoft Project is as follows (and works correctly): .OnAction = "Macro ""DoSomething""" ... where DoSomething is the method to execute. I would like to pass a parameter to that method but can't find a way to pass it with this syntax. Does anybody have an idea how to do this? I'm getting the feeling that this is an impossible task, but maybe there's some VBA secret I'm not aware of. Please note that VBA in MS Project seems to have its quirks and is slightly different than VBA for Excel or Access. This seems to be the case for the OnAction property which needs the extra Macro keyword to work correctly. If I'm wrong here please enlighten me.

  • ASP.NET/VB/SQL: trying to insert data, getting error "no value given for required parameters"

    - by Sara
    I am pretty sure this is a basic syntax error, I am new at this and basically figuring things out by trial and error... I am trying to insert data from textboxes into an Access database, where the primary key fields in tableCourse are prefix and course_number. It keeps giving me the "no value given for one or more required parameters" error. Here is my codebehind: Protected Sub Wizard1_FinishButtonClick(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.WizardNavigationEventArgs) Handles Wizard1.FinishButtonClick 'Collect Data Dim myDept = txtDept.Text Dim myFirst = txtFirstName.Text Dim myLast = txtLastName.Text Dim myPrefix = txtCoursePrefix.Text Dim myNum = txtCourseNum.Text 'Define Connection Dim myConn As New OleDbConnection myConn.ConnectionString = AccessDataSource1.ConnectionString 'Create commands Dim myIns1 As New OleDbCommand("INSERT INTO tableCourse (department, name_first, name_last, prefix, course_number) VALUES (@myDept, @myFirst, @myLast, @myPrefix, @myNum)", myConn) 'Execute the commands myConn.Open() myIns1.ExecuteNonQuery() End Sub

  • MSBuild conditionals depending on task parameters

    - by jalf
    In MSBuild it's straightforward to define, say, a PropertyGroup which depends on the value of a property Foo: <PropertyGroup Conditional="'$(Foo)'=='Bar'" /> Is it also possible for the conditional to depend on a task parameter? For example, I'd like to use the value of the Link task's SubSystemparameter roughly like this: <PropertyGroup Conditional="'$(Link/SubSystem)'=='Console'" /> but don't know if it is possible, and if it is, what the correct syntax is. I'm pretty new to MSBuild though, so it's perfectly possible that I've missed something.

  • How can I write this Table Valued Function as a Stored Procedure?

    - by Alex
    I have the following TVF for fulltext search: FUNCTION [dbo].[Fishes_FullTextSearch] (@searchtext nvarchar(4000), @limitcount int) RETURNS TABLE AS RETURN SELECT * FROM Fishes INNER JOIN CONTAINSTABLE(Fishes, *, @searchtext, @limitcount) AS KEY_TBL ON Fishes.Id = KEY_TBL.[KEY] When I'm using this TVF, it doesn't return a collection of objects of type Fish (which I want!) - instead LINQ creates a new result type which includes all "Fish" fields and the fields Key and Rank. In another question, it was suggested that I rewrite this TVF into a stored procedure for it to return Fish objects only. Can someone help me do this please? Also, it needs to be ordered by Rank. Thank you!

  • Dynamic, reflective SignalHandler in Java

    - by pilcrow
    How do I install signal handling logic iff sun.misc.Signal is available? Background First generation of my code looked something like this: class MyApp { public static void main(String[] args) { ... Signal.handle(term_sig, new SignalHandler() { public void handle(Signal sig) { ... } }); ... } } I believe I understand how to reflectively test for and use signal handlers -- Class.forName("sun.misc.Signal"), reflectively call Signal.handle, and so forth. My impulse was simply to instantiate another anonymous inner class with the dynamically obtained SignalHandler class, but I think that's just wishful syntax.

  • TypeError: Cannot find function 1.0.

    - by Newtopian
    Hi, I have a script and I'm almost done but I get this error and frankly I have no idea what is wrong here. I'm rather new to Javascript so I suspect I did something wrong in the syntax somewhere. Here is an extract from the script containing the offending line : var gc = 0; var seg; var segCount = 0; var groupCount = 0; var groupLevel = 0; var segments = new Array(); var sk = ""; for(gc = 0; gc = groupDelimiters.length) break; if(seg.name() == groupDelimiters[gc]) { //ok we start another group grKeys.startNewGroup(groupLevel, groupCriterionExtractors[groupLevel](segCount), groupCount); groupLevel = gc + 1; //This line is flagged with the error in the title groupCount++; } } ideas, pointers, any help would be appreciated.

  • Using module include in OCaml

    - by Geoff
    In OCaml 3.11, I want to "extend" an existing module using the include directive, like so: module MyString = struct include String let trim s = ... end No problem. But now I want to expose this module's type explicitly (i.e. in a .mli file). I want something like this: module MyString : sig include String val trim : string -> string end But the include syntax is not correct because String refers to a module, not a module type (and the compiler does indeed barf). How can I refer to the module type for String here (without having write it out explicitly in a sig expression)? Thanks!

  • Writing .NET in dynamic language?

    - by tillda
    I'm confused by the possibility of writing .NET in dynamic languages, such as (Iron)Ruby. Particularly, I've seen code in IronRuby that used generics (...foo[String]), but I'm not aware of this feature in Ruby as it seems nonsense to me in dynamic languages. So, when I write .NET app in IronRuby, how is it with type safety and compilation? I thought that it is just as dynamic as Ruby everywhere else. I thought that if the Ruby syntax is OK all the type checking would be done at the runtime. Also, as far as I know, .NET itself is type-oriented - there are classes that heavily utilize the mentioned generics. How is this handled? And what about delegates? In dynamic languages I can have almost function-spaghetti and sometimes, its just fine (like hacking UI in javascript). Or do I have to care even about generic delegates?

  • Tutorials for an experienced C# user to learn C++

    - by Tim R.
    Are there any good resources for learning C++ that a C# user could use, which don't require knowledge of C? I have quite a good knowledge of C# via courses in my University's game development program (in a 300 level course right now) but now I need to use C++ for a project. I would use a beginner tutorial but they are so hard for me to follow and learn the basic syntax because they start so slowly. I found a few of tutorials for switching from C++ to C#, but none in the other direction. I do have a little bit of Objective C practice from iPhone programming as well.

  • Programming Quiz [closed]

    - by arin-s-rizk
    Hi one of my mates sent me this quiz see if you can guess the answers I will post mine later. In this quiz, some tasks related to the compilation process are listed. For each one of them, specify the part of the compiler that is responsible of performing it. Here are the possible answers: Lexical analyzer Parser Semantic analyzer None of the above Just fill the right choice (the number only) in the blank after each task: Checking that the parentheses in an expression are balanced _ _ _ _ _ Removing comments from the program _ _ _ _ _ Grouping input characters into "tokens" _ _ _ _ _ Reporting an error to the programmer about a missing (;) at the end of a C++ statement _ _ _ _ _ Checking if the type of the RHS (Right-Hand Side) of an assignment (=) is compatible with the LHS (Left-Hand Side) variable _ _ _ _ _ Converting the (AST) Abstract Syntax Tree into machine language _ _ _ _ _ Reporting an error about a strange character like '^' in a C++ program _ _ _ _ _ Optimizing the AST _ _ _ _ _

  • What's the silliest programming mistake you've ever done? [closed]

    - by bgo
    Despite not being a professional programmer, i use python or c to accomplish simple tasks. Once I needed a nasty equation to use with various data for physics lab. I thought that it would take a few hours if i used some mechanic calculator. Then i've written a python script to make things easier but something was wrong. After finding my mistakes one of which was forgetting to put ":", i realized that it had already took 2-3 hours, not to mention inventing satanic arithmetic techniques since i thought the errors was caused by my math :) Sometimes when you don't see it, you don't see it! Now i can find the syntax errors without thinking for a moment :) Any similar annoying mistakes that you've experienced?

  • passing Perl method results as a reference

    - by arareko
    Some XML::LibXML methods return arrays instead of references to arrays. Instead of doing this: $self->process_items($xml->findnodes('items/item')); I want to do something like: $self->process_items(\$xml->findnodes('items/item')); So that in process_items() I can dereference the original array instead of creating a copy: sub process_items { my ($self, $items) = @_; foreach my $item (@$items) { # do something... } } I can always store the results of findnodes() into an array and then pass the array reference to my own method, but let's say I want to try a reduced version of my code. Is that the correct syntax for passing the method results or should I use something different? Thanks!

  • MVC route with id and sub-action

    - by Dan Revell
    I can't figure out what I need to do with MVC routing to make this work Here's my one route: routes.MapHttpRoute( name: "DefaultApi", routeTemplate: "{controller}/{id}/{action}", defaults: new { id = RouteParameter.Optional, action = RouteParameter.Optional } ); The request /Shipments/ works great. The request /Shipments/3/Packages works great. The request /Shipments/3 however fails with the error: Multiple actions were found that match the request: System.Linq.IQueryable`1[Api.Controllers.RequisitionsController+PackageRequisitionWithTracking] GetPackageRequisitions(Int32) on type Api.Controllers.RequisitionsController Api.Models.ShipmentRequisition GetShipmentRequisitions(Int32) on type Api.Controllers.RequisitionsController It can't seem to differentiate between: public ShipmentRequisition GetShipmentRequisitions(int id) and [ActionName("Packages")] public IQueryable<PackageRequisitionWithTracking> GetPackageRequisitions(int id) I would have thought the lack of action name on the get shipment by id would allow that route to work.

  • Cakephp, Retreive Data for HABTM Models using conditional find

    - by ion
    There are 2 Models: Project & Category that are bind with HABTM relationship. I would like to perform a search from projects controller that can do the following: FIND all DISTINCT Project.scedule WHERE Category.slug != 'uncategorised' Apologies for the syntax, I'm no sequel expert. What I have managed to do is to retrieve all projects that do not belong to Category uncategorised into an array however I'm not sure as to how to search again the array result for DISTINCT Project.schedule values (needed to fill out a form drop down) I hope I made myself clear.

  • MyFaces Test Framework not working with JSF 2.1

    - by Karl Kildén
    we have a lot of tests that uses Myfaces Test Framework for JSF 2.0. http://myfaces.apache.org/test/index.html Problem is we can't get it to work with JSF 2.1. Does anyone know a workaround or a way to solve this? When we run the tests we get the following error: java.lang.IllegalStateException: Application was not properly initialized at startup, could not find Factory: javax.faces.application.ApplicationFactory It works fine with jsf 2.0 though. A typical use case in our code: // code block; assertFalse("Error message not expected. ", facesContext .getMessages().hasNext()); JSF 2.1 has a few syntax changes so my guess would be that's the problem.

  • Optional URL fragment in Codeigniter?

    - by DA
    This is maybe a simple syntax question or possibly a best-practices question in terms of codeigniter. I should start by saying I'm not a PHP or Codeigniter person so trying to get up to speed on helping on a project. I've found the CI documentation fairly good. The one question I can't find an answer to is how to make part of a URL optional. An example the CI documentation uses is this: example.com/index.php/products/shoes/sandals/123 and then the function used to parse the URI: function shoes($sandals, $id) For my example, I'd like to be able to modify the URL as such: example.com/index.php/products/shoes/all So, if no ID is passed, it's just ignored. Can that be done? Should that be done? A second question unrelated to my problem but pertaining to the example above, why would the variable $sandals be used as in the example, the value is 'sandals'? Shouldn't that variable be something like $shoetype?

  • Accessing a nested hash in a controller

    - by Magicked
    I have the following (snipped) parameters passed into my controller. Parameters: {"commit"=>"OK", "action"=>"set_incident_incident_status_id", "id"=>"1", "controller"=>"incidents", "incident"=>{"incident_status_id"=>"1"}} I know that if I want to select the incident, I can do: @incident = Incident.find(params[:id]) How do I access the "incident"={"incident_status_id"="1"}? I thought to try something like: @incident_status = IncidentStatus.find(params[:incident => :incident_status_id]) But that didn't work. I'm assuming it's just a syntax problem at this point, and I haven't found a solution yet. Any help would be much appreciated!
