  • ActionScript display zero value

    - by bwong
    It seems the number Datatype handles zeros and nulls the same. I need to display a zero value on the screen, but AS displays nothing. When it's saved, the value is saved as a zero, and therefore shows up zero on the screen. Is there a way to display the zero value using a new object? public class myObject{ private var numVar:Number } My AS file: var temp:MyObject temp.numVar = 0; When I debug, temp.numVar contains a value of 0, but does not show anything on the UI. If this object is then saved to the DB, and then displayed to the UI, it shows a 0. My question is - how do I get temp.numVar to display 0 before persistenting it to the DB?

  • Combining the value of GetLastError and a custom error message

    - by Jessica
    I have a function that returns a different DWORD value for each case there is an error. So I have the following defines: #define ERR_NO_DB_CONNECTION 0x90000 #define ERR_DB_NOT_OPEN 0x90001 #define ERR_DB_LOCKED 0x90002 #define ERR_DB_CONN_LOST 0x90003 Now, I return those values when an error occurs. I need to also return the value of GetLastError in the same return. No, I can't read it later. I tried combining it different ways, eg: return ERR_DB_NOT_OPEN + GetLastError(); and then extract the error by subtracting the value of ERR_DB_NOT_OPEN but since I need to use this in functions where there can be several return values it can get quite complex to do that. Is there any way to achieve this? I mean, combine the value + GetLastError and extract them later? Code is appreciated. Thanks Jess.

  • Name Value Pairs in a ComboBox

    - by JamesB
    I'm convinced this must be a common problem, but I can't seem to find a simple solution... I want to use a combobox control with name value pairs as the items. ComboBox takes TStrings as its items so that should be fine. Unfortunately the drawing method on a combobox draws Items[i] so you get Name=Value in the box. I'd like the value to be hidden, so I can work with the value in code, but the user sees the name. Any Ideas?

  • Adding a web address to a <a href="value">

    - by Michael Robinson
    I have an upload script that write a index.html file, I modified it to mail me the results, however the point to the root, since the email isn't in the root, the image doesn't load. How do I append the code to add "http://www.home.html/uploaded" prior to the ". $value ." so that the images show up in the email. Here is portion of PHP that assigns the images to a $result: // Process value of Imagedata field, this is JPEG-files array foreach ($_FILES[Imagedata][name] as $key => $value) { $uploadfile = $destination_dir . basename($_FILES[Imagedata][name][$key]); if (move_uploaded_file($_FILES['Imagedata']['tmp_name'][$key], $uploadfile)) { $result .= "File uploaded: <a href='". $value . "'>" . $value . "</a><br>"; } } // $result .= "<br>"; Here is what I'm now receiving in the email, : <!doctype html public "-//w3c//dtd html 4.0 transitional//en"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>Upload results</title> </head> <body> AdditionalStringVariable: pass additional data here<br><a> href='gallery_grannylovesthis_l.jpg'><img border = '0' src='QIU_thumb_gallery_grannylovesthis_l.jpg'/></a><br><br><br>File uploaded: <a href='gallery_grannylovesthis_l.jpg'>gallery_grannylovesthis_l.jpg</a><br><br> GlobalControlData: PHOTO_VISIBILITY : 2<br> GlobalControlData: PHOTO_DESCR : Requiredtest<br> GlobalControlData: PHOTO_TITLE : Requiredtest<br><br>gallery_grannylovesthis_l.png<br> control: , value: <br> </body> </html> Thanks in advance for any guidance...I have a feeling it's something simple.

  • Visual Studio keeps inserting absurd default property value in designer file

    - by Bugz R us
    i have a simple usercontrol with following properties: public partial class RichTextEditorControl : UserControl { public string EditorText { get { return richTextBox1.Rtf; } set { richTextBox1.Rtf = value; } } public string EditorPlainText { get { return richTextBox1.Text; } set { richTextBox1.Text = value; } } } Now whenever I EDIT a form which contains this control, VS fills its designer file with the following code line, and then throws a designer error : this.richTextEditorControl1.EditorPlainText = global::Project.Resources.MyResources_de_DE.SomeString; Now I don't know where it gets this value from ??? I've searched entire solution, and nowhere there's mention of this var, except for 1 file, where it's needed ... Moreover, the code VS writes, has an error in it ?! It doesn't compile ... The only thing I can do is edit the designer file, but the next time I have to edit the form with the designer, the same error happens again ... Where on earth is VS getting this value from ??

  • How to call virtual function of an object in C++

    - by SoonDead
    I'm struggling with calling a virtual function in C++. I'm not experienced in C++, I mainly use C# and Java so I might have some delusions, but bear with me. I have to write a program where I have to avoid dynamic memory allocation if possible. I have made a class called List: template <class T> class List { public: T items[maxListLength]; int length; List() { length = 0; } T get(int i) const { if (i >= 0 && i < length) { return items[i]; } else { throw "Out of range!"; } }; // set the value of an already existing element void set(int i, T p) { if (i >= 0 && i < length) { items[i] = p; } else { throw "Out of range!"; } } // returns the index of the element int add(T p) { if (length >= maxListLength) { throw "Too many points!"; } items[length] = p; return length++; } // removes and returns the last element; T pop() { if (length > 0) { return items[--length]; } else { throw "There is no element to remove!"; } } }; It just makes an array of the given type, and manages the length of it. There is no need for dynamic memory allocation, I can just write: List<Object> objects; MyObject obj; objects.add(obj); MyObject inherits form Object. Object has a virtual function which is supposed to be overridden in MyObject: struct Object { virtual float method(const Input& input) { return 0.0f; } }; struct MyObject: public Object { virtual float method(const Input& input) { return 1.0f; } }; I get the elements as: objects.get(0).method(asdf); The problem is that even though the first element is a MyObject, the Object's method function is called. I'm guessing there is something wrong with storing the object in an array of Objects without dynamically allocating memory for the MyObject, but I'm not sure. Is there a way to call MyObject's method function? How? It's supposed to be a heterogeneous collection btw, so that's why the inheritance is there in the first place. If there is no way to call the MyObject's method function, then how should I make my list in the first place?

  • Defining relationship in value objects using Hibernate

    - by kate
    Hi, We have three tables .We need to get data from these tables based upon particular conditions. Like if TableA.columv=TableB.columc=tableC.column then get data. We are using value objects to map Objects to relations. Question is how to maintain these relation ships in value objects. And how to retrieve data from it. We have one value object per table.

  • Rails - before_filter than includes updated object

    - by Sam
    I have a before filter than calculates a percentage that needs to include the object that is being updated. Is there a one liner in rails that takes care of this? for example and this is totaly made up: Object.find(:all, :include = :updated_object) Currently I'm sending the object that is getting updated to the definition that calculates the percentage and that works but its making things messy.

    - by Matthew Cox
    I have a custom control that has a hidden field. Upon postback I want to obtain the value stored in it, but it's always an empty string. any thoughts? I am performing client-side manipulation of the hidden field values and have verified in firebug that the fields are correct before issue a post back Here is the setup: public class DualListPanel : SWebControl, INamingContainer { protected IList<DlpItem> UnassignedList { get; set; } protected IList<DlpItem> AssignedList { get; set; } private HiddenField assignedItemsField, unassignedItemsField; public DualListPanel() { CssClass = "DualListPanel"; EnableViewState = true; } #region ViewState protected override void LoadViewState(object savedState) { var state = savedState as object[]; UnassignedList = state[0] as List<DlpItem>; AssignedList = state[1] as List<DlpItem>; base.LoadViewState(state[2]); } protected override object SaveViewState() { object[] state = new object[3]; state[0] = UnassignedList; state[1] = AssignedList; state[2] = base.SaveViewState(); return state; } #endregion #region WebControl Overrides protected override void CreateChildControls() { assignedItemsField = new HiddenField(); assignedItemsField.ID = "HiddenAssignedItems"; assignedItemsField.EnableViewState = true; unassignedItemsField = new HiddenField(); unassignedItemsField.ID = "HiddenUnassignedItems"; unassignedItemsField.EnableViewState = true; Controls.Add(assignedItemsField); Controls.Add(unassignedItemsField); base.CreateChildControls(); } #endregion #region Item Lists Retrieval public string GetCommaDelimUnassignedItems() { return unassignedItemsField.Value; } public string GetCommaDelimAssignedItems() { return assignedItemsField.Value; } #endregion }

  • Reference variable to an object instantiated/initialized in another class in Java

    - by Alex
    The reason I'm asking is because I'm getting NullPointerException. I now this is very easy but I'm pretty new programming and find this a bit confusing. So say I have initialized an object in a class and want to access that same object from another class. Like now for instance I'm working on a small Chess game, in my model Game class I have an instance of Board, an object. Board, in turn, has an array of Squares. Square[][]. Game has board, board has Square[][]. Now if I want to access the Square[][] through the object board (in Game) of type Board. Do I just declare a variable with the same name and type or do I have to initialize it again? Board board OR Board board = new Board(); Note, I have already initialized board in the class Game so if I do it again, won't they be two totally different Board objects?

  • SSRS - Sort table based on column value

    - by Ehsan
    I am trying to sort the following table: hYear hSale ------------------------------------ [year] =Count(Fields!sale.Value) The table only has one row group (year) and no column group. I'd like to: -initially sort the table based on the calculated value; is it possible? -add interactive sort to calculated column based on the value. I assume I should sort 'Detail rows', but what will be the sort expression?

  • ActiveX Deployment

    - by balexandre
    We have used for 8 years an ActiveX builder in Delphi and we are now using it on Internet Explorer over the internet (and not on local machine as it was always been the process until here) As today we use this object in the HTML: <object id="ActiveX" classid="CLSID:8EC68701-329D-4567-BCB5-9EE4BA43D358" width="14" height="14"> <param name="tabName" value="AccountPlan"> </object> My question is, what are the viable methods to deploy an Active X Control over HTTP/S, what parameters should I need to append to tell where to find it (http url) and download a new one if newer is available? I got into this article from MSDN Library but refers to VB5.0 and it's dated 1997 ... Just wanna know what can I do now, as probably the tools evolved since last century All help is appreciated, Thank you.

  • Pass object from webserver to client

    - by user362914
    I developed a C# web application that calls a web-service which returns a base64 encoded array (PDF file). I then convert that array into a UCOMIStream object (I know it is obsolete, but the DLL that I am using requires it as a parameter). I use the following code to do the conversion which works perfectly. I can pass this object to the DLL so that I can print the PDF. This works great on the Webserver, but the requirement is to print it locally. Byte[] bBuffer = statementOut.statementcycle.statementdata.content; int size = bBuffer.Length; IntPtr mem = Marshal.AllocHGlobal(size); Marshal.Copy(bBuffer, 0, mem, size); // Create an OLE Stream object. System.Runtime.InteropServices.UCOMIStream str; //obsolete but the createstreamonhglobal outputs it CreateStreamOnHGlobal(mem, true, out str); The DLL resides on the client so I am able to use ActiveX to create the object using javascript and/or VBscript;however, I have not been able to figure out how to get the stream object to the client to pass to the DLL. How can this be achieved?

  • controling a float value with javascript

    - by kawtousse
    Hi, to control my input type and verify that its value is pretty a float in my form i deal with it in javascript like that: function verifierNombre () { var champ=document.getElementById("nperformed"); var str = champ.value; if(str.value==' '){champ.focus();} if (isNaN(str)) { alert("Invalid Valid! the field must be a number"); champ.focus(); return false; } return true; } but it still false because it doesn't accept really floats. so when entering a value like '11,2' the alert is declenched. I want to know how can I control float values with javascript. thanks.

  • Use from value from backing bean in javascript

    - by AlfonsSocken
    What I want is to use a boolean value from applicationContext.xml (Jboss configuration file) in my javascript. Currently I use Spring to inject a value configured in applicationContext.xml into my backingbean. Then I put an output text in my jsp like this <h:outputText id="idValue" styleClass="foo" value="" rendered="#{bean.isRendered}"/> In my JavaScript I try following jQuery(function(){ bRedirect = jQuery("#foo").value != undefined; ... All this looks so terrible to me, even though it works fine. There must be a smarter way than doing what I do. Note that I am running JSF1.2 and therefore must use jQuery instead of $ and also select by unique class (foo) and not by id, which may be bad practice as well. Thank you in advance. alfons

  • How can I find out how much memory an instance of a C++ class consumes?

    - by Shadow
    Hi, I am developing a Graph-class, based on boost-graph-library. A Graph-object contains a boost-graph, so to say an adjacency_list, and a map. When monitoring the total memory usage of my program, it consumes quite a lot (checked with pmap). Now, I would like to know, how much of the memory is exactly consumed by a filled object of this Graph-class? With filled I mean when the adjacency_list is full of vertices and edges. I found out, that using sizeof() doesn't bring me far. Using valgrind is also not an alternative as there is quite some memory allocation done previously and this makes the usage of valgrind impractical for this purpose. I'm also not interested in what other parts of the program cost in memory, I want to focus on one single object. Thank you.
