  • problem with jquery sortable of ul with childrens - how to allow li to be sorted only on the same le

    - by Y.G.J
    $(document).ready(function() { $("#test-list").sortable({ items: "> li", handle : '.handle', axis: 'y', opacity: 0.6, update : function () { var order = $('#test-list').sortable('serialize'); $("#info").load("process-sortable.asp?"+order+"&id=catid&order=orderid&table=tblCats"); } }); $("#test-sub").sortable({ containment: "ul", items: "li", handle : '.handle2', axis: 'y', opacity: 0.6, update : function () { var order = $('ul').sortable('serialize'); $("#info").load("process-sortable.asp?"+order+"&id=catid&order=orderid&table=tblCats"); } }); }); <ul id="test-list"> <li id="listItem_10">first<img align="middle" src="Themes/arrow.png" class="handle" /></li> <li id="listItem_8">second<img align="middle" src="Themes/arrow.png" class="handle" /> <ul id="test-sub"> <li id="listItem_4><img align="middle" src="Themes/arrow.png" class="handle2" /></li> <li id="listItem_3"><img align="middle" src="Themes/arrow.png" class="handle2" /></li> <ul id="test-sub"> <li id="listItem_9"><img align="middle" src="Themes/arrow.png" class="handle2" /></li> </ul> </li> </ul> </li> </ul> the problems i have: sorting the main ul is working but not all the time - i will try to fix that my own but if there is a problem with the code here and not the one in proccess-sortable - tell me. moving li in the main ul is ok but the sub or the sub of the sub is having problem - i can drag something from one sub to it's sub or the other way too - i don't want that to happend. i want to be able to drag li and by selecting that one that only this ul group will send to proccess-sortable to be updated - how can i catch the specific ul of li i am draging?

  • weird access denied issue with WMI

    - by stackunderflow1
    I'm seeing a weird access denied issue with WMI. we're trying to create a diff disk based on a parent vhd in a windows service app that runs under network service (machine account is an admin). everything works fine when we create the diff disk on other machine using wmi - we use an admin user account. however, we cannot do this on a local machine as wmi doesn't take user cred for the local machine. so thought network service account already should have access for this, it seems like it doesn't and even if we run the service under an admin service account, it fails. any pointers???

  • Why 'initWithObjectsAndKeys:' doesn't throw a casting warning? (NSDictionary)

    - by rubdottocom
    Sorry if the question isn't correct, I'm very new in Objective-C. I understand why this code throw the Warning: "warning: passing argument 1 of 'initWithObjectsAndKeys:' makes pointer from integer without" NSDictionary *dictNames = [[NSDictionary alloc] initWithObjectsAndKeys: 3, @"", 4, @"", 5, @"",nil]; Keys and Values of a NSDictionary must be NSObject and not fundamental types, like the integers 3, 4 and 5. (Correct me if necessary). But I don't understand why this warning dissapears with the only "correct typing" of the first Key. NSDictionary *dictNames = [[NSDictionary alloc] initWithObjectsAndKeys: [NSNumber numberWithInteger:3], @"", 4, @"", 5, @"",nil]; It's because NSDictionary assumes the type of the other Keys? Is correct this manner of initialization?

  • Lenovo Wi-Fi Replacement

    - by user22910
    I recently got my T500 with a very poor signal Wi-Fi, Thinkpad BGN, a Realtek chipset. I would like to replace my Wi-Fi card with either the Intel WiFi Link 5100 or 5300. However, I read somewhere that Lenovo specfically "whitelist" their Wi-Fi cards to only work with their laptops. I could not find any of the Intel Wi-Fi, moreover any Wi-Fi cards on the Lenovo site. So, I went to hunt around in Amazon and found several sellers. Plus what sort of card do I require? There is a difference between mini cards and the full sized card, though I do not know which one my laptop supports. Here are the specifications for my laptop: http://privatepaste.com/8b0537bce0 I would like to have confirmation which one of these specific cards as posted below will work on my laptop (or the one you recommend to have): Intel Wifi Link 5300 Intel WiFi Link 5100 - Network adapter - PCI Express Mini Card - 802.11b, 802.11a, 802.11g, 802.11n (draft 2.0) Intel WiFi Link 5100 - Network adapter - PCI Express Half Mini Card - 802.11b, 802.11a, 802.11g, 802.11n (draft) Intel WiFi Link 5300 - Network adapter - PCI Express Mini Card - 802.11b, 802.11a, 802.11g, 802.11n (draft)

    - by Asian Angel
    Do you have a lot of tabs open no matter what time of day it is and find sorting through the tabs list frustrating? Then get control back with the List All Tabs Menu extension for Firefox. Before If you have a large number of tabs open using the “Tab List Menu” can start to become a little awkward. You can use your mouse’s middle button to scroll through the list or the tiny arrow button at the bottom but there needs to be a better way to deal with this. After Once you have installed the extension you will notice two differences in the “Tab List Menu”. There will be a search box available and a nice scrollbar for those really long lists. A closer look at the search box and scrollbar setup… Depending on your style you can use the scrollbar to look for a particular page or enter a search term and watch that list become extremely manageable. A closer look at our much shorter list after conducting a search. Definitely not hard to find what we were looking for at all. Conclusion If you are someone who has lots of tabs open at once throughout the day then the List All Tabs Menu extension might be the perfect tool to help you sort and manage those tabs.

  • Problems with Database Search Code (asp.net vb)

    - by Phil
    Here is a sample of my database search code: Dim sql As String = "Select * From Table Where " Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim andor As Boolean = AndOr1.SelectedValue 'selection can be AND or OR (0 / 1) 'Code for when the user selects AND If NameSearch.Text.ToString IsNot String.Empty And andor = 0 Then sql += "Surname LIKE '%" & name & "%' AND " End If If EmailSearch.Text.ToString IsNot String.Empty And andor = 0 Then sql += "Email LIKE '%" & email & "%' AND " End If If CitySearchBox.Text.ToString IsNot String.Empty And andor = 0 Then sql += "City LIKE '%" & city & "%' AND " End If 'Code for when the user selects OR If NameSearch.Text.ToString IsNot String.Empty And andor = 1 Then sql += "(Surname LIKE '%" & name & "%' OR " End If If EmailSearch.Text.ToString IsNot String.Empty And andor = 1 Then sql += "Email LIKE '%" & email & "%') OR " End If If CitySearchBox.Text.ToString IsNot String.Empty And andor = 1 Then sql += "(City LIKE '%" & city & "%' OR " End If sql = CleanString(sql) End Sub When the user selects AND (as andor.selectedvalue(0)) then the sql is produced fine like this; Select * From Table Where Surname LIKE '%test%' AND Email LIKE '%test%' AND City LIKE '%test%' But if the user selects OR (as andor.selectedvalue(1)), nothing is outputted except; Select * From Table Where Im sure the controls have values so are not string.empty and when the user selects OR the correct value 1 is being assigned to andor.

  • Brother bPAC SDK - Examples only print after Form is shown

    - by Scoregraphic
    Hi there We have a small Brother Barcode printer which we like to control from a WCF Service. Brother has an API called bPAC SDK version 3 which allows to print those labels. But the problem arises, as soon as we want to print from code only without showing a windows with a button on it. As an addition, this happens only if you want to print a QR-code as barcode. Standard EAN-codes seems to work. Below is a small piece of code which outputs the stuff to a bitmap instead of the printer (debugging reasons). DocumentClass doc = new DocumentClass(); if (doc.Open(templatePath)) { doc.GetObject("barcode1").Text = txtCompany.Text; doc.GetObject("barcode2").Text = txtName.Text; doc.Export(ExportType.bexBmp, testImagePath, 300); doc.Close(); } If this is called by a button click, it perfectly works. If this is called in Form.Show-event, it perfectly works. If this is called in Form.Load-event, it does NOT work. If this is called in a Form constructor, it does NOT work. If this is called somewhere else (without forms), it does NOT work. DocumentClass and related classes are COM-objects, so I guess the form setup/show process seems to do something which is not done without opening forms. I tried calling CoInitialize with a p/invoke, but it hadn't changed anything. Is there anyone out there willing and able to help me? Are there any alternatives which (also) MUST be able to print directly on our Brother printer? Thanks lot.

  • Python code to use a regular expression to make sure a string is alphanumeric plus . - _

    - by Warlax
    Hi, I looked and searched and couldn't find what I needed although I think it should be simple (if you have any Python experience, which I don't). Given a string, I want to verify, in Python, that it contains ONLY alphanumeric characters: a-zA-Z0-9 and . _ - examples: Accepted: bill-gates Steve_Jobs Micro.soft Rejected: Bill gates -- no spaces allowed [email protected] -- @ is not alphanumeric I'm trying to use: if re.match("^[a-zA-Z0-9_.-]+$", username) == True: But that doesn't seem to do the job...

  • How do you debug MySQL stored procedures?

    - by Cory House
    My current process for debugging stored procedures is very simple. I create a table called "debug" where I insert variable values from the stored procedure as it runs. This allows me to see the value of any variable at a given point in the script, but is this is there a better way to debug MySQL stored procedures?

  • Modifying CollectionEditor in PropertyGrid

    - by Chris
    I currently have a list containing Call's, which is the base class. If I want to add derived classes of Call to the list, I know to do the following. public class CustomCollectionEditor : System.ComponentModel.Design.CollectionEditor { private Type[] types; public CustomCollectionEditor(Type type) : base(type) { types = new Type[] { typeof(Call), typeof(CappedCall) }; } protected override Type[] CreateNewItemTypes() { return types; } } public class DisplayList { public DisplayList() { } [Editor(typeof(CustomCollectionEditor), typeof(UITypeEditor))] [DataMember] public List<Call> ListCalls { get; set; } } My questions is there anyway of moving where you mark up the Type[] containing all possible types the list can contain? I thought of adding the following to my CustomCollectionEditor class, but this doesn't work. public CustomCollectionEditor(Type type, List<Type> types_) : base(type) { types = types_.ToArray(); } It would be ideal if I could mark up which classes the CustomCollectionEditor needed to be aware of in the DisplayList class somehow.

  • Setting up SVN (subvsersion) to manage our companies files, how to exclude large files from being ve

    - by Roeland
    Me and two other guys recently started our own web development company. We each work from our homes and have decided we want to keep one central location for all of our files. These files include word documents, spreadsheets, client files, designs.. etc. Anything pertaining to our company. I have a pretty solid internet connection and a windows 2008 server box sitting at home so I set up a subversion repository. Our file repository will look something like this. Clients Company A Design (photoshop files, wireframes, concepts) Documents ( logins, quotes, proposals etc) Site Backups Company B Design Documents Site Backups Prospects Company C Company D Our Company Our Website Documents (contract, operating procudres) My question is in regards to design files. The photoshop files that my designer works with range in sizes from 10mb to 100mb. I don't think we need to keep these files version-ed as this would eat up space incredibly fast. How do I go about controlling which files get version-ed, and which files are just stored. What I am thinking is that all documents need to be version-ed, and any files other then that should not be. Any help would be appreciated, thanks! Edit I am also curious whether this is the way to go. I just like this system since it keeps version of all my documents and at the same time. Also essentially I will have 3 backups in 3 different locations (3 local copies) so no need for backing it up. I am unsure of how svn would perform as purely a huge file repository.

  • Passing Object to Service in WCF

    - by hgulyan
    Hi, I have my custom class Customer with its properties. I added DataContract mark above the class and DataMember to properties and it was working fine, but I'm calling a service class's function, passing customer instance as parameter and some of my properties get 0 values. While debugging I can see my properties values and after it gets to the function, some properties' values are 0. Why it can be so? There's no code between this two actions. DataContract mark workes fine, everything's ok. Any suggestions on this issue? I tried to change ByRef to ByVal, but it doesn't change anything. Why it would pass other values right and some of integer types just 0? Maybe the answer is simple, but I can't figure it out. Thank You. <DataContract()> Public Class Customer Private Type_of_clientField As Integer = -1 <DataMember(Order:=1)> Public Property type_of_client() As Integer Get Return Type_of_clientField End Get Set(ByVal value As Integer) Type_of_clientField = value End Set End Property End Class <ServiceContract(SessionMode:=SessionMode.Allowed)> <DataContractFormat()> Public Interface CustomerService <OperationContract()> Function addCustomer(ByRef customer As Customer) As Long End Interface type_of_client properties value is 6 before I call addCustomer function. After it enters that function the value is 0. UPDATE: The issue is in instance creating. When I create an instance of a class on client side, that is stored on service side, some of my properties pass 0 or nothing, but when I call a function of a service class, that returns a new instance of that class, it works fine. What's is the difference? Could that be serialization issue?

  • UITextView - text shifts out of view when editing

    - by Jeff
    I have a tableHeaderView with a UITextView in it. The view loads from a nib. The UITextView does not have any scrolling turned on. The reason I am using it is simply that it wraps text over two lines. I gave it just enough room to fit two lines of text. The data that I prepopulate works just fine, and is aligned in the center vertically whether it is two or one line. The problem is that when I edit the cell via the UI, the text shifts up to the point that the top half of it is cut off. When exiting editing, it stays this way. Not sure I have any relevant code to show, but hopefully the explanation makes sense. I can't seem to find anyone else having this issue and I cannot imagine what it could be. I've played around with turning scrolling on and off, toying with the size of the field, and everything else I could play with to no avail. Thanks Jeff

  • Is it worthwhile to implement observer pattern in PHP?

    - by Extrakun
    I have been meaning to make use of design pattern in PHP, such as the observer pattern, but that I have to recreate the observers' relationship each time the page is loaded pains me. As references are saved as a new concrete objects in session, there is no way to preserve relationships between subscribers and their observers unless you use a GUID or some other properties to form a lookup, and store that property instead. With the cost of recreating the relationships each time a page is loaded, is it worthwhile to use design patterns such as observers in PHP, compared to having a clean design? Any real-world experience to share?

  • Foreign key not stored in child entity (one-to-many)

    - by Kamil Los
    Hi, I'm quite new to hibernate and have stumbled on this problem, which I can't find solution for. When persisting parent object (with one-to-many relationship with child), the foreign-key to this parent is not stored in child's table. My classes: Parent.java @javax.persistence.Table(name = "PARENT") @Entity public class PARENT { private Integer id; @javax.persistence.Column(name = "ID") @Id @GeneratedValue(strategy=GenerationType.AUTO) public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } private Collection<Child> children; @OneToMany(mappedBy = "parent", fetch = FetchType.EAGER, cascade = {CascadeType.ALL}) @Cascade({org.hibernate.annotations.CascadeType.ALL}) public Collection<Child> getChildren() { return children; } public void setChildren(Collection<Child> children) { this.children = children; } } Child.java @javax.persistence.Table(name = "CHILD") @Entity @IdClass(Child.ChildId.class) public class Child { private String childId1; @Id public String getChildId1() { return childId1; } public void setChildId1(String childId1) { this.childId1 = childId1; } private String childId2; @Id public String getChildId2() { return childId2; } public void setChildId2(String childId2) { this.childId2 = childId2; } private Parent parent; @ManyToOne @javax.persistence.JoinColumn(name = "PARENT_ID", referencedColumnName = "ID") public Parent getParent() { return parent; } public void setParent(Operation parent) { this.parent = parent; } public static class ChildId implements Serializable { private String childId1; @javax.persistence.Column(name = "CHILD_ID1") public String getChildId1() { return childId1; } public void setChildId1(String childId1) { this.childId1 = childId1; } private String childId2; @javax.persistence.Column(name = "CHIILD_ID2") public String getChildId2() { return childId2; } public void setChildId2(String childId2) { this.childId2 = childId2; } public ChildId() { } @Override public boolean equals(Object o) { if (this == o) return true; if (o == null || getClass() != o.getClass()) return false; ChildId that = (ChildId) o; if (childId1 != null ? !childId1.equals(that.childId1) : that.childId1 != null) return false; if (childId2 != null ? !childId2.equals(that.childId2) : that.childId2 != null) return false; return true; } @Override public int hashCode() { int result = childId1 != null ? childId1.hashCode() : 0; result = 31 * result + (childId2 != null ? childId2.hashCode() : 0); return result; } } } Test.java public class Test() { private ParentDao parentDao; public void setParentDao(ParentDao parentDao) { this.parentDao = parentDao; } private ChildDao childDao; public void setChildDao(ChildDao childDao) { this.childDao = parentDao; } test1() { Parent parent = new Parent(); Child child = new Child(); child.setChildId1("a"); child.setChildId2("b"); ArrayList<Child> children = new ArrayList<Child>(); children.add(child); parent.setChildren(children); parent.setValue("value"); parentDao.save(parent); //calls hibernate's currentSession.saveOrUpdate(entity) } test2() { Parent parent = new Parent(); parent.setValue("value"); parentDao.save(parent); //calls hibernate's currentSession.saveOrUpdate(entity) Child child = new Child(); child.setChildId1("a"); child.setChildId2("b"); child.setParent(parent); childDao.save(); //calls hibernate's currentSession.saveOrUpdate(entity) } } When calling test1(), both entities get written to database, but field PARENT_ID in CHILD table stays empty. The only workaround I have so far is test2() - persisting parent first, and then the child. My goal is to persist parent and its children in one call to save() on Parent. Any ideas?

  • PNRP + dont see Global_ on Windows 7

    - by schmoopy
    Hi, Im trying to test out PNRP in a simple app that either registers or resolves. On my Vista machine when i run 'netsh p2p pnrp cloud show list' .... I see Global_ When i try this from my Windows 7 machine i do not see Global_ i only have LinkLocal_... I can see i have an IPV6 address on the Windows 7 machine (via ipconfig) I may not just understand it enough yet - very poorly documented and most of the documentation is from Orca, 2007,etc. Makes me wonder if PNRP will just end up being another uddi.microsoft.com (i know they are nothing alike, but my point is...)

  • Need help in resolving a compiler error: error: invalid conversion from ‘int’ to ‘GIOCondition’

    - by michael
    I have a simple cpp file which uses GIO. I have stripped out everything to show my compile error: Here is the error I get: My.cpp:16: error: invalid conversion from ‘int’ to ‘GIOCondition’ make[2]: *** [My.o] Error 1 Here is the complete file: #include <glib.h> static gboolean read_socket (GIOChannel *gio, GIOCondition condition, gpointer data) { return false; } void createGIOChannel() { GIOChannel* gioChannel = g_io_channel_unix_new(0); // the following is the line causing the error: g_io_add_watch(gioChannel, G_IO_IN|G_IO_HUP, read_socket, NULL); } I have seen other example using gio, and I am doing the same thing in term of calling G_IO_IN|G_IO_HUP. And the documentation http://www.gtk.org/api/2.6/glib/glib-IO-Channels.html, said I only need to include , which I did. Can you please tell me how to resolve my error? One thing I can think of is I am doing this in a cpp file. But g_io_add_watch is a c function? Thank you for any help. I have spent hours on this but did not get anywhere.

  • Where would I use a bitwise operator in JavaScript?

    - by J-P
    I've read this (http://stackoverflow.com/quest...), so I know what bitwise operators are but I'm still not clear on how one might use them... Can anyone offer any real-world examples of where a bitwise operator would be useful in JavaScript? Thanks. Edit: Just digging into the jQuery source I've found a couple of places where bitwise operators are used, for example: (only the & operator) // Line 2756: event.which = (event.button & 1 ? 1 : ( event.button & 2 ? 3 : ( event.button & 4 ? 2 : 0 ) )); // Line 2101 var ret = a.compareDocumentPosition(b) & 4 ? -1 : a === b ? 0 : 1;
