  • Setting Global Variables in VBA

    - by dennis96411
    I'm currently making an "OS" in PowerPoint and I need to know how to set global variables for the settings. I made a module called "Settings" containing: Public Sub Settings() Option Explicit Public UserName, UserIcon, Background, BrowserHomePage As String Public SetupComplete As Boolean SetupComplete = False UserName = "Administrator" UserIcon = Nothing Background = Nothing BrowserHomePage = Nothing 'Set the variables UserName.Text = UserName End Sub Now on the "log in" screen, I have a text box named "UserName". I then made a button just to test out the variables. The button does this: Private Sub CommandButton1_Click() UserName.Value = UserName End Sub The text box has no value when I click the button. I'm super new at VBA, and would like to know how to do this. Also, if anyone knows how to automatically execute codes when starting the PowerPoint, that would be fantastic.

  • can the keyword 'this' be used in an abstract class in java

    - by Reddy
    I tried with below example, it is working fine. I expected it to pick sub-class's value since object won't be created for super class (as it is abstract). But it is picking up super class's field value only. Please help me understand what is the concepts behind this? abstract class SuperAbstract { private int a=2; public void funA() { System.out.println("In SuperAbstract: this.a "+a); } } class SubClass extends SuperAbstract { private int a=34; } I am calling new SubClass.funA(); I am expecting it to print 34, but it is printing 2.

  • List filtering: list comprehension vs. lambda + filter

    - by Agos
    I happened to find myself having a basic filtering need: I have a list and I have to filter it by an attribute of the items. My code looked like this: list = [i for i in list if i.attribute == value] But then i thought, wouldn't it be better to write it like this? filter(lambda x: x.attribute == value, list) It's more readable, and if needed for performance the lambda could be taken out to gain something. Question is: are there any caveats in using the second way? Any performance difference? Am I missing the Pythonic Way™ entirely and should do it in yet another way (such as using itemgetter instead of the lambda)? Thanks in advance

  • check existense between two IEnumerable

    - by sunglim
    IEnumerable<String> existedThings = from mdinfo in mdInfoTotal select mdinfo.ItemNo; IEnumerable<String> thingsToSave = from item in lbXReadSuccess.Items.Cast<ListItem>() select item.Value; Here are two IEnumerable. I want to check whether a value in existedThings exist in thingsToSave. O.K. I can do that with 3 line code. bool hasItemNo; foreach(string itemNo in existedThings) hasItemNo= thingsToSave.Contains(itemNo); But, It looks dirty. I just want to know if there better solution.

  • Is this multi line if statement too complex?

    - by AndHeCodedIt
    I am validating input on a form and attempting to prompt the user of improper input(s) based on the combination of controls used. For example, I have 2 combo boxes and 3 text boxes. The 2 combo boxes must always have a value other than the first (default) value, but one of three, or two of three, or all text boxes can be filled to make the form valid. In one such scenario I have a 6 line if statement to try to make the test easily readable: if ((!String.Equals(ComboBoxA.SelectedValue.ToString(), DEFAULT_COMBO_A_CHOICE.ToString()) && !String.IsNullOrEmpty(TextBoxA.Text) && !String.Equals(ComboBoxB.SelectedValue.ToString(), DEFAULT_COMBO_B_CHOICE.ToString())) || (!String.IsNullOrEmpty(TextBoxB.Text) || !String.IsNullOrEmpty(TextBoxC.Text))) { //Do Some Validation } I have 2 questions: Should this type of if statement be avoided at all cost? Would it be better to enclose this test in another method? (This would be a good choice as this validation will happen in more than one scenario) Thanks for your input(s)!

  • How are managed the sequences by JPA and Hibernate?

    - by romaintaz
    Hi all, I am using Hibernate in my project, and many of my entities use a sequence for their technical keys. For example: @Entity @Table(name = "T_MYENTITY") @SequenceGenerator(name = "S_MYENTITY", sequenceName = "S_MYENTITY") public class MyEntity { @Id @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "S_MYENTITY") @Column(name = "MY_ENTITY_ID") private Long entityId; ... } I have two questions about the ID generated by Hibernate when a new object of this class is persisted: Why SequenceGenerator (from javax.persistence) has a default value of allocationSize set to 50 instead of 1? What are the interests of that? What is the default algorithm used by Hibernate to calculate the generated ID? It seems that Hibernate uses the value returned by the sequence hosted by my Oracle database, but then modify it before assigning it to my entity...

  • Remove duplicates in entries, scala way

    - by andersbohn
    I have a list of entries stating a production value in a given interval. Entries stating the exact same value at a later time adds no information and can safely be left out. case class Entry(minute:Int, production:Double) val entries = List(Entry(0, 100.0), Entry(5, 100.0), Entry(10, 100.0), Entry(20, 120.0), Entry(30, 100.0), Entry(180, 0.0)) Experimenting with the scala 2.8 collection functions, so far I have this working implementation: entries.foldRight(List[Entry]()) { (entry, list) => list match { case head :: tail if (entry.production == head.production) => entry :: tail case head :: tail => entry :: list case List() => entry :: List() } } res0: List[Entry] = List(Entry(0,100.0), Entry(20,120.0), Entry(30,100.0), Entry(180,0.0)) Any comments? Am I missing out on some scala magic?

  • updating button text and other issues

    - by droidus
    I am trying to update my button. but the problem is that I can't have an ID/name with it, right, when doing this? so what if I have multiple forms on the page, and must identify the button? <input type="submit" value="Upload my File" style="background-color:#00F; font-size:14px; padding:1em;" onclick=" this.value='Please wait...'; this.disabled = true; var theForm = this.form; window.setTimeout(function(){theForm.submit();},3);" /> also, the button doesn't seem to wait 3 seconds when I hit the submit button.

  • C++ conversion operator between types in other libraries

    - by Dave
    For convenience, I'd like to be able to cast between two types defined in other libraries. (Specifically, QString from the Qt library and UnicodeString from the ICU library.) Right now, I have created utility functions in a project namespace: namespace MyProject { const icu_44::UnicodeString ToUnicodeString(const QString& value); const QString ToQString(const icu_44::UnicodeString& value); } That's all well and good, but I'm wondering if there's a more elegant way. Ideally, I'd like to be able to convert between them using a cast operator. I do, however, want to retain the explicit nature of the conversion. An implicit conversion should not be possible. Is there a more elegant way to achieve this without modifying the source code of the libraries? Some operator overload syntax, perhaps?

  • Go - Concurrent method

    - by nevalu
    How to get a concurrent method? In my case, the library would be called from a program to get a value to each argument str --in method Get()--. When it's used Get() then it assigns a variable from type bytes.Buffer which it will have the value to return. The returned values --when it been concurrently called-- will be stored into a database or a file and it doesn't matter that its output been of FIFO way (from method). type test struct { foo uint8 bar uint8 } func NewTest(arg1 string) (*test, os.Error) {...} func (self *test) Get(str string) ([]byte, os.Error) { var format bytes.Buffer ... } I think that all code inner of method Get() should be put inner of go func() {...}(), and then to use a channel. Would there be a problem if it's called another method from Get()? Or would it also has to be concurrent?

  • Why does JAXB not create a member variable in its generated code when an XML schema base type and subtype have the same element declared in them?

    - by belltower
    I have a question regarding with regard to JAXB generated classes. As you can I see, I have a complex type, DG_PaymentIdentification1, declared in my schema. Its a restriction of PaymentIdentification1. DG_PaymentIdentification1 is also identical to PaymentIdentification1. I also have a type called DG_CreditTransferTransactionInformation10 which has a base type of CreditTransferTransactionInformation10 and is identical to it. I have included the relevant XML schema snippets below. <xs:complexType name="DG_PaymentIdentification1"> <xs:complexContent> <xs:restriction base="PaymentIdentification1"> <xs:sequence> <xs:element name="InstrId" type="DG_Max35Text_REF" minOccurs="0"/> <xs:element name="EndToEndId" type="DG_Max35Text_REF" id="DG-41"/> </xs:sequence> </xs:restriction> </xs:complexContent> </xs:complexType> <xs:complexType name="PaymentIdentification1"> <xs:sequence> <xs:element name="InstrId" type="Max35Text" minOccurs="0"/> <xs:element name="EndToEndId" type="Max35Text"/> </xs:sequence> </xs:complexType> <xs:complexType name="DG_CreditTransferTransactionInformation10"> <xs:complexContent> <xs:restriction base="CreditTransferTransactionInformation10"> <xs:sequence> <xs:element name="PmtId" type="DG_PaymentIdentification1"/> <xs:simpleType name="DG_Max35Text_REF"> <xs:restriction base="DG_NotEmpty35"> <xs:pattern value="[\-A-Za-z0-9\+/\?:\(\)\.,'&#x20;]*"/> </xs:restriction> </xs:simpleType> <xs:simpleType name="Max35Text"> <xs:restriction base="xs:string"> <xs:minLength value="1"/> <xs:maxLength value="35"/> </xs:restriction> </xs:simpleType> JAXB generates the following java class for DG_PaymentIdentification1: @XmlAccessorType(XmlAccessType.FIELD) @XmlType(name = "DG_CreditTransferTransactionInformDGion10") public class DGCreditTransferTransactionInformation10 extends CreditTransferTransactionInformation10 { } My question is why doesnt the DGCreditTransferTransactionInformation10 generated class have a variable of type DG_PaymentIdentification1 in the generated code? The base class CreditTransferTransactionInformation10 does have a type PaymentIdentification1 declared in it. Is there any way of ensuring that DGCreditTransferTransactionInformation10 will have a DG_PaymentIdentification1 in it?

  • Modify a given number to find the required sum?

    - by Gaurav
    A friend of mine sent me this question. I haven't really been able to come up with any kind of algorithm to solve this problem. You are provided with a no. say 123456789 and two operators * and +. Now without changing the sequence of the provided no. and using these operators as many times as you wish, evaluate the given value: eg: given value 2097 Solution: 1+2+345*6+7+8+9 Any ideas on how to approach problems like these?

    Hi. Is there a way to convert different named xml nodes into one class when deserializing an XML Example XML: <items> <aaa>value</aaa> <bbb>value</bbb> </items> Normaly i would write: [XmlRoot("items")] class Items { [XmlElement("aaa")] public string aaa; [XmlElement("bbb")] public string bbb; } But now i would like to do something like this [XmlRoot("items")] class Items { [XmlElement("aaa")] [XmlElement("bbb")] public List<string> item; } Here I would love if "aaa" and "bbb" was added to the same list.

  • Jquery question : maintain focus upon appending a row?

    - by PoppySeedsAndAppleJuice
    The function below checks whether the id entered is already in the database, and if it is, then it adds some html to the table. I'm not sure if it's directly related to my issue or not, but, essentially, a user will place the focus on the id input field and enters an id. Using ajax, it posts to a php script and returns data if rows are found and nothing if it doesn't. If the user then tabs over to the next input field (zipcode), or clicks in another input field, they essentially have to do so twice. The cursor "flashes" in the field briefly and then focuses out. I tried adding in a focus(), but the behavior didn't change. So, the html looks like this: <table id="tableSearchData" class="searchlist" style="width: 789px;"> <thead> <tr> <th>ID</th> <th>Zip Code</th> <th>Radius (in miles)</th> </tr> </thead> <tbody> <tr class="odd"> <!-- PROBLEM is described below --> <!-- User clicks in <input name="id[]"> and ID is checked --> <!-- User presses "tab" or clicks in <input name="zipcode[] (in the *same* row) and cursor flashes, then goes out of focus so that the user has to click in the field again --> <td class="center sorting_1"><input type="text" value="" name="id[]"></td> <td class="center"><input type="text" value="" name="zipcode[]"></td> <td class="center"><input type="text" value="" name="radius[]"></td> </tr> </tbody> </table> Here's the jquery function... Like I said, I'm not sure if it's directly related to the problem I'm having, but, thought I should include it because I suppose it's likely there is something happening there... $("#tableSearchData > tbody > tr > td > input[name=id[]]").focusout(function() { var row = $(this).closest("tr").get(0); var sData = $(this).serialize(); $.ajax({ type: "POST", url: "checkid.php", data: sData, success: function(html) { $(row).replaceWith(html); $(".preset").each(function() { $(this).attr("disabled", true); }); $(row).closest("input[name=zipcode[]]").focus(); } }); });

  • WPF UserControl event called only once?

    - by 742
    Hi Everyone, I need to bind two-way a property of a user control to a property of a containing user control. I also need to set a default value to the property from code in the child (cannot be done easily from XAML tags). If I call my code from the child constructor, the value is set in the parent but the change callback routine is not triggered (my understanding is that the parent doesn't yet exist at the time the child is created). My current workaround is to catch the Loaded event of the child and to call the code from the handler. Howver as Loaded is called more than once, I need to set a flag to set the property only the first time. I don't like this way, but I don't know if there is a single shot event that could be used, or if this can be done otherwise. Any feedback based on your experience?

  • Accessing a variable passed by jquery using php

    - by celenius
    How does php access a variable passed by JQuery? I have the following code: $.post("getLatLong.php", { latitude: 500000}, function(data){ alert("Data Loaded: " + data); }); but I don't understand how to access this value using php. I've tried $userLat=$_GET["latitude"]; and $userLat=$_GET[latitude]; and then I try to print out the value (to check that it worked) using: echo $userLat; but it does not return anything. I can't figure out how to access what is being passed to it.

  • Is it wise to rely on default features of a programming language?

    - by George Edison
    Should I frequently rely on default values? For example, in PHP, if you have the following: <?php $var .= "Value"; ?> This is perfectly fine - it works. But what if assignment like this to a previously unused variable is later eliminated from the language? (I'm not referring to just general assignment to an unused variable.) There are countless examples of where the default value of something has changed and so much existing code was then useless. On the other hand, without default values, there is a lot of code redundancy. What is the proper way of dealing with this?

  • XPath to compare two distinct attributes of two elements

    - by user364902
    Suppose I have this XML: <x> <e s="1" t="A"/> <e s="2" t="A"/> <e s="1" t="B"/> </x> Is there any way to write an xpath to find any nodes named "e" which have the same value of @s as another node but a different value of @t for the same node. The first part is easy: //e[@s = //e/@s] as is the second part: //e[@t != //e[@t]] But I don't see any way to construct an xpath that compares two different attributes for two separate elements "e". Is there a way within the xpath syntax, or is it hopeless?

  • Where does static variable work in C# page. At Application level or Page Level

    - by Shantanu Gupta
    I had an interview today and every thing was going very good, but then an interviewer asked me a question Where Does Static Variable Work in C#- At Application Level or At Page Level. I was not very much clear about this answer as I only knew that static variables are stored on heap and I didn't knew anything about web related thing about it. Then tried to make me more clear by giving an example that in a page I am using static variable and three users are accessing the page one of the user updates the value of static variable, What value will be visible to remaining two users an old copy or the update will be reflected.

  • How do you get the ID of a control in ASP.NET

    - by James
    I am attempting to loop through an array of numbers, match them to the checkbox they they are associated with, and checkmark that box. My checkbox is set up like: <input type="checkbox" runat="server" id="someID" name="somename" value="1234" /> My code when the page loads currently looks like: foreach (string interest in interests_Var){ foreach (var c in Page.Controls) { } } interests_Var is my array containing different numbers. We'll assume one of them is 1234. While looping through the page controls, I want to compare the value of the control to my number. If it equals my number, I want to then apply the attribute checked="checked". I'm assuming I have to find the ID of the control I am using, then use that ID to add a new attribute. Or is there a way I can add the attribute using the c variable? I'm not dead set on this setup, so if you know a better way, I'm all ears. Thanks for any help and suggestions.
