  • Using WSH (VBS) with iMacros - how do they do it?

    - by Carl
    (iMacros For Firefox 6.6.5.0; Firefox 3.6.3; Windows XP Pro SP3 w/all updates) I made an iMacro to select "load next 25" (comments) on a web page (CNN.COM). Unfortunately, iMacros doesn't appear to do looping (do the above until that string doesn't appear on the page anymore - i.e. all the comments are loaded). I tried putting {!iloop} in the TAG command, and it didn't work - then I read it wouldn't. So I tried the example at http://wiki.imacros.net/Loop_after_Query_or_Login I can't find any information on how to actually run the script in the above example. I searched Google and found VBS scripting is handled with .wsh files with Windows XP Pro. (The examples and other references there say Windows does VBS natively, so I looked up how with Google.) So I made the following .wsh file (modified the above example): Option Explicit Dim iim1, iret 'initialize iMacros instance set iim1 = CreateObject ("imacros") iret = iim1.iimInit() do while not iret < 0 iret = iim1.iimPlay("Load All CNN Comments") loop ' tell user we're done msgbox "End." ' exit iMacros instance and quit script iret = iim1.iimExit() Wscript.Quit() Here's the iMacro: (Load All CNN Comments.iim) VERSION BUILD=6650406 RECORDER=FX TAG POS=1 TYPE=A ATTR=TXT:Load<SP>next<SP>25 WAIT SECONDS=#DOWNLOADCOMPLETE# The iMacro works by itself - I press Play (left iMacro panel) and the next 25 comments load on the CNN.com page in the current tab. I put the .wsh file in the ...\iMacros\Macros directory - with the iMacro "Load All CNN Comments.iim" When I run the .wsh file (by just double clicking on it's icon - I created it with Notepad, and Windows gave it an icon for that file type - it's executable) I get the message from "Windows Script Host" - "There is no script file specified." I wasn't actually expecting it to work, as I don't see how Windows would know to call iMacros to run the iim macro. It would be nice if there was a simple, COMPLETE, example of how to use a VBS script with iMacros, that isn't bogged down with unnecessary complication like filling in a form, loading multiple pages, etc. I can't find ANY example. So what do I need to do to get this to work? I just installed iMacros yesterday, because I am constantly having the problem that there are hundred of comments after a CNN.com article, and loading 25 more at a time until they are all on the page makes it impractical to read any replies to my comments. It would also be nice if I could run the Macro from Firefox, rather than by double clicking on some file somewhere. Thanks for any help.

  • SQL syntax error

    - by Robert
    Im using Microsoft SQL Server which I think is T-SQL or ANSI SQL. I want to search a database with a string. The matches that fit the begging of the string should come first then sort alphabetically. I.e. If the table contains FOO, BAR and RAP a search for the string 'R' should yield: RAP BAR In that order. Here is my attempt: SELECT Name FROM MyTable WHERE (Name LIKE '%' + @name + '%') ORDER BY (IF(Name LIKE @name + '%',1,0)) The error message is: "must declare scalar variable @name"

  • Getting data from function loaded after current function

    - by Hwang
    I have 2 functions, 1 loaded before another. Some value are determine by the other function data, but since one of it has to load before the other 1, how should I get the data that is loaded after current function? private function wMessage():void { Message.width=Name.width+20; } private function wName():void { Name.x=(Message.x+Message.textWidth)-Name.textWidth; Name.y=Message.y+Message.height; } I've taken out some other unnecessary codes, but as you can see Name position is set according by the position + width of Message, but I want Message's width to be not smaller than Name

  • Error messages for model validation using data annotations

    - by oneBelizean
    Given the follow classes: using System.ComponentModel.DataAnnotations; public class Book{ public Contact PrimaryContact{get; set;} public Contact SecondaryContact{get; set;} [Required(ErrorMessage="Book name is required")] public string Name{get; set;} } public class Contact{ [Required(ErrorMessage="Name is required")] public string Name{get; set;} } Is there a clean way I can give a distinct error message for each instance of Contact in Book using DataAnnotations? For example, if the name was missing from the PrimaryContact instance the error would read "primary contact name is required". My current solution is to create a validation service that checks the model state for field errors then remove said errors and add them back using the specific language I'd like.

  • How can I instantiate a base class and then convert it to a derived class?

    - by Eric
    I was wondering how to do this, consider the following classes public class Fruit { public string Name { get; set; } public Color Color { get; set; } } public class Apple : Fruit { public Apple() { } } How can I instantiate a new fruit but upcast to Apple, is there a way to instantiate a bunch of Fruit and make them apples with the name & color set. Do I need to manually deep copy? Of course this fails Fruit a = new Fruit(); a.Name = "FirstApple"; a.Color = Color.Red; Apple wa = a as Apple; System.Diagnostics.Debug.Print("Apple name: " + wa.Name); Do I need to pass in a Fruit to the AppleCTor and manually set the name and color( or 1-n properties) Is there an better design to do this?

  • Basic Array Iteration in Ruby

    - by michaelmichael
    What's a better way to traverse an array while iterating through another array? For example, if I have two arrays like the following: names = [ "Rover", "Fido", "Lassie", "Calypso"] breeds = [ "Terrier", "Lhasa Apso", "Collie", "Bulldog"] Assuming the arrays correspond with one another - that is, Rover is a Terrier, Fido is a Lhasa Apso, etc. - I'd like to create a dog class, and a new dog object for each item: class Dog attr_reader :name, :breed def initialize(name, breed) @name = name @breed = breed end end I can iterate through names and breeds with the following: index = 0 names.each do |name| dog = Dog.new("#{name}", "#{breeds[index]}") index = index.next end However, I get the feeling that using the index variable is the wrong way to go about it. What would be a better way?

  • How do you get XML::Pastor to set xsi:type for programmatically generated elements?

    - by Derrick
    I'm learning how to use Perl as an automation test framework tool for a Java web service and running into trouble generating xml requests from the Pastor generated modules. The problem is that when including a type that extends from the required type for an element, the xsi:type is not included in the generated xml string. Say, for example, I want to generate the following xml request from the modules that XML::Pastor generated from my xsd: <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <PromptAnswersRequest xmlns="http://mycompany.com/api"> <Uri>/some/url</Uri> <User ref="1"/> <PromptAnswers> <PromptAnswer xsi:type="textPromptAnswer" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <Prompt ref="2"/> <Children> <PromptAnswer xsi:type="choicePromptAnswer"> <Prompt ref="1"/> <Choice ref="2"/> </PromptAnswer> </Children> <Value>totally</Value> </PromptAnswer> </PromptAnswers> </PromptAnswersRequest> What I'm getting currently is this: <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <PromptAnswersRequest xmlns="http://mycompany.com/api"> <Uri>/some/url</Uri> <User ref="1"/> <PromptAnswers> <PromptAnswer> <Prompt ref="2"/> <Children> <PromptAnswer> <Prompt ref="1"/> <Choice ref="2"/> </PromptAnswer> </Children> <Value>totally</Value> </PromptAnswer> </PromptAnswers> </PromptAnswersRequest> Here are some relavent snippets from the xsd: <xs:complexType name="request"> <xs:sequence> <xs:element name="Uri" type="xs:anyURI"/> </xs:sequence> </xs:complexType> <xs:complexType name="promptAnswersRequest"> <xs:complexContent> <xs:extension base="api:request"> <xs:sequence> <xs:element name="User" type="api:ref"/> <xs:element name="PromptAnswers" type="api:promptAnswerList"/> </xs:sequence> </xs:extension> </xs:complexContent> </xs:complexType> <xs:complexType name="promptAnswerList"> <xs:sequence> <xs:element name="PromptAnswer" type="api:promptAnswer" minOccurs="0" maxOccurs="unbounded"/> </xs:sequence> </xs:complexType> <xs:complexType name="promptAnswer" abstract="true"> <xs:sequence> <xs:element name="Prompt" type="api:ref"/> <xs:element name="Children" type="api:promptAnswerList" minOccurs="0"/> </xs:sequence> </xs:complexType> <xs:complexType name="textPromptAnswer"> <xs:complexContent> <xs:extension base="promptAnswer"> <xs:sequence> <xs:element name="Value" type="api:nonEmptyString" minOccurs="0"/> </xs:sequence> </xs:extension> </xs:complexContent> </xs:complexType> And here are relavent parts of the script: my $promptAnswerList = new My::API::Type::promptAnswerList; my @promptAnswers; my $promptAnswerList2 = new My::API::Type::promptAnswerList; my @textPromptAnswerChildren; my $textPromptAnswer = new My::API::Type::textPromptAnswer; my $textPromptAnswerRef = new My::API::Type::ref; $textPromptAnswerRef->ref('2'); $textPromptAnswer->Prompt($textPromptAnswerRef); my $choicePromptAnswer = new My::API::Type::choicePromptAnswer; my $choicePromptAnswerPromptRef = new My::API::Type::ref; my $choicePromptAnswerChoiceRef = new My::API::Type::ref; $choicePromptAnswerPromptRef->ref('1'); $choicePromptAnswerChoiceRef->ref('2'); $choicePromptAnswer->Prompt($choicePromptAnswerPromptRef); $choicePromptAnswer->Choice($choicePromptAnswerChoiceRef); push(@textPromptAnswerChildren, $choicePromptAnswer); $promptAnswerList2->PromptAnswer(@textPromptAnswerChildren); $textPromptAnswer->Children($promptAnswerList2); $textPromptAnswer->Value('totally'); push(@promptAnswers, $pulseTextPromptAnswer); push(@promptAnswers, $textPromptAnswer); I haven't seen this addressed anywhere in the documentation for the XML::Pastor modules, so if anyone can point me at a good reference for its use it would be greatly appreciated. Also, I'm only using XML::Pastor because I don't know of any other modules that can do this, so if any of you know of something either easier to use, or more well maintained, please let me know about that too!

  • EF4 CTP5 Code First approach ignores Table attributes

    - by Justin
    I'm using EF4 CTP5 code first approach but am having trouble getting it to work. I have a class called "Company" and a database table called "CompanyTable". I want to map the Company class to the CompanyTable table, so have code like this: [Table(Name = "CompanyTable")] public class Company { [Key] [Column(Name = "CompanyIdNumber", DbType = "int")] public int CompanyNumber { get; set; } [Column(Name = "CompanyName", DbType = "varchar")] public string CompanyName { get; set; } } I then call it like so: var db = new Users(); var companies = (from c in db.Companies select c).ToList(); However it errors out: Invalid object name 'dbo.Companies'. It's obviously not respecting the Table attribute on the class, even though it says here that Table attribute is supported. Also it's pluralizing the name it's searching for (Companies instead of Company.) How do I map the class to the table name?

  • Stuck on an ASP.NET/WCF WSDL Parsing Error

    - by Vaccano
    I have a WCF Web Service that my ASP.NET app uses. It has been working fine for quite some time. I just added in a Dev Express Grid (and the Dev Express DLLs) and a new page that uses them and now I am getting parsing errors on the WSDL.

  • How to assign class property as display data member in datagridview

    - by KoolKabin
    hi guys, I am trying to display my data in datagridview. I created a class with different property and used its list as the datasource. it worked fine. but I got confused how to do that in case we have nested class. My Classes are as follows: class Category property UIN as integer property Name as string end class class item property uin as integer property name as string property mycategory as category end class my data list as follows: dim myDataList as list(of Item) = new List(of Item) myDataList.Add(new Item(1,"item1",new category(1,"cat1"))) myDataList.Add(new Item(2,"item2",new category(1,"cat1"))) myDataList.Add(new Item(3,"item3",new category(1,"cat1"))) myDataList.Add(new Item(4,"item4",new category(2,"cat2"))) myDataList.Add(new Item(5,"item5",new category(2,"cat2"))) myDataList.Add(new Item(6,"item6",new category(2,"cat2"))) Now I binded the datagridview control like: DGVMain.AutoGenerateColumns = False DGVMain.ColumnCount = 3 DGVMain.Columns(0).DataPropertyName = "UIN" DGVMain.Columns(0).HeaderText = "ID" DGVMain.Columns(1).DataPropertyName = "Name" DGVMain.Columns(1).HeaderText = "Name" DGVMain.Columns(2).DataPropertyName = "" **'here i want my category name** DGVMain.Columns(2).HeaderText = "category" DGVMain.datasource = myDataList DGVMain.refresh() I have tried using mycategory.name but it didn't worked. What can be done to get expected result? Is there any better idea other than this to accomplish the same task? Edited My question as per comment: I have checked the link given by u. It was nice n very usefull. Since the code was in c# i tried to convert it in vb. Everything went good but failed at a point of case sensitive and next one is that i had my nested class name itemcategory and my property name was category. there it arouse the problem. it didn't searched for category but it searched for itemcategory. so confused on it. My Code as follows: Private Sub DGVMain_CellFormatting(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellFormattingEventArgs) Handles DGVMain.CellFormatting Dim DGVMain As DataGridView = CType(sender, DataGridView) e.Value = EvaluateValue(DGVMain.Rows(e.RowIndex).DataBoundItem, DGVMain.Columns(e.ColumnIndex).DataPropertyName) End Sub Private Function EvaluateValue(ByRef myObj As Object, ByRef myProp As String) As String Dim Ret As String = "" Dim Props As System.Reflection.PropertyInfo() Dim PropA As System.Reflection.PropertyInfo Dim ObjA As Object If myProp.Contains(".") Then myProp = myProp.Substring(0, myProp.IndexOf(".")) Props = myObj.GetType().GetProperties() For Each PropA In Props ObjA = PropA.GetValue(myObj, New Object() {}) If ObjA.GetType().Name = myProp Then Ret = EvaluateValue(ObjA, myProp.Substring(myProp.IndexOf(".") + 1)) Exit For End If Next Else PropA = myObj.GetType().GetProperty(myProp) Ret = PropA.GetValue(myObj, New Object() {}).ToString() End If Return Ret End Function

  • Can I execute SQL statements directly in a JDO environment?

    - by Carl Rosenberger
    I am using Datanucleus JDO on top of HSqlDb. I would like to execute the following SQL statement to tell HsqlDb to set the write delay to 0: "SET WRITE_DELAY 0" Is there a way I can do this from a JDO PersistenceManager or a PersistenceManagerFactory? On a sidenote: I have tried to modify write_delay by using the following connection URL: jdbc:hsqldb:file:data/hsqldb/dbbench;write_delay=false It didn't work. I debugged the HsqlDb sources and I could still see the write delay being set to 10 seconds.

  • SQLAlchemy automatically converts str to unicode on commit

    - by Victor Stanciu
    Hello, When inserting an object into a database with SQLAlchemy, all it's properties that correspond to String() columns are automatically transformed from <type 'str'> to <type 'unicode'>. Is there a way to prevent this behavior? Here is the code: from sqlalchemy import create_engine, Table, Column, Integer, String, MetaData from sqlalchemy.orm import mapper, sessionmaker engine = create_engine('sqlite:///:memory:', echo=False) metadata = MetaData() table = Table('projects', metadata, Column('id', Integer, primary_key=True), Column('name', String(50)) ) class Project(object): def __init__(self, name): self.name = name mapper(Project, table) metadata.create_all(engine) session = sessionmaker(bind=engine)() project = Project("Lorem ipsum") print(type(project.name)) session.add(project) session.commit() print(type(project.name)) And here is the output: <type 'str'> <type 'unicode'> I know I should probably just work with unicode, but this would involve digging through some third-party code and I don't have the Python skills for that yet :)

  • MongoDB - how to join parent and child products by reference

    - by Jaro
    my mongo collection stores products. There are two product types: child and parent. Parent product holds array of its child as reference. Use case: use mydb; child1 = { _id: 1, name: "Child 1", is_child: true, is_parent: false, children : [] } child2 = { _id: 2, name: "Child 2", is_child: true, is_parent: false, children : [] } parent = { _id: 3, name: "Parent product", is_child: false, is_parent: true, children : [1, 2] } db.product.insert( [child1, child2, parent] ); And I'm looking for any query returning { _id: 3, name: "Parent product", is_child: false, is_parent: true, children: [ { _id: 1, name: "Child 1", is_child: true, is_parent: false, children : [] }, { _id: 2, name: "Child 2", is_child: true, is_parent: false, children : [] } ] } I'm newbie to mongodb, but I guess an usage of map-reduce could solve the problem. Can anyone advice? Thx

  • Retrieve names of running processes

I have a user application that needs to determine if a particular process is running. Here's what I know about the process: The name The user (root) It should already be running, since it's a LaunchDaemon, which means Its parent process should be launchd (pid 1) I've tried several ways to get this, but none have worked so far. Here's what I've tried: Running ps and parsing the output. This works, but it's slow (fork/exec is expensive), and I'd like this to be as fast as possible. Using the GetBSDProcessList function listed here. This also works, but the way in which they say to retrieve the process name (accessing kp_proc.p_comm from each kinfo_proc structure) is flawed. The resulting char* only contains the first 16 characters of the process name, which can be seen in the definition of the kp_proc structure: #define MAXCOMLEN 16 //defined in param.h struct extern_proc { //defined in proc.h ...snip... char p_comm[MAXCOMLEN+1]; ...snip... }; Using libProc.h to retrieve process information: pid_t pids[1024]; int numberOfProcesses = proc_listpids(PROC_ALL_PIDS, 0, NULL, 0); proc_listpids(PROC_ALL_PIDS, 0, pids, sizeof(pids)); for (int i = 0; i < numberOfProcesses; ++i) { if (pids[i] == 0) { continue; } char name[1024]; proc_name(pids[i], name, sizeof(name)); printf("Found process: %s\n", name); } This works, except it has the same flaw as GetBSDProcessList. Only the first portion of the process name is returned. Using the ProcessManager function in Carbon: ProcessSerialNumber psn; psn.lowLongOfPSN = kNoProcess; psn.highLongOfPSN = 0; while (GetNextProcess(&psn) == noErr) { CFStringRef procName = NULL; if (CopyProcessName(&psn, &procName) == noErr) { NSLog(@"Found process: %@", (NSString *)procName); } CFRelease(procName); } This does not work. It only returns process that are registered with the WindowServer (or something like that). In other words, it only returns apps with UIs, and only for the current user. I can't use -[NSWorkspace launchedApplications], since this must be 10.5-compatible. In addition, this only returns information about applications that appear in the Dock for the current user. I know that it's possible to retrieve the name of running processes (since ps can do it), but the question is "Can I do it without forking and exec'ing ps?". Any suggestions?
