• emacs error: "Symbol's value as variable is void: hostname"

  - by Florian Pilz

  After I installed emacs this error occurs every time on startup. It prevents me from installing plugins, e.g. auctex via aptitude. I already tried to install a plugin by hand (rails for ruby), but doesn't work. The error doesn't contain the message "hostname", but the hostname of my PC is displayed ("bloodredangel-ubuntu"). I changed my hostname to "bloodredangel", but the error message stays the same. While I changed my hostname I saw that in /etc/hostname were two entries: 127.0.0.1 bloodredangel-ubuntu I already asked this question in an ubuntu forum but they couldn't help. They recognised an misconfigured /etc/hosts file, which I corrected, but from time to time these incorrect configurations get attached by something. I didn't add them by hand, maybe it has something to do with the issue. The misconfigurations looked like this: 127.0.0.1 127.0.0.1 bloodredangel-ubuntu localhost.localdomain localhost 127.0.0.1 127.0.0.1:8080 bloodredangel-ubuntu localhost.localdomain localhost I didn't found a solution on the internet, so I hope I will find help here finally.

• asp.net mvc - bootstrapping object via model binder

  - by csetzkorn

  Hi, I have a domain object Thing which can contain several Categories. So I have implemented my HTML helper to create a checkbox group of all possible Categories. I have no problem receiving: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Create(Thing Thing, List<string> Categories) However I am wondering whether I could use a custom Model binder to use just this: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Create(Thing Thing) So basically I am looking for a way to use the model binder to bootstrap the object tree/graph. Any pointers appreciated. Thanks. Christian

• Minimum permissions to allow COM Object to be Instantiated when running as LocalService

  - by Paul Farry

  I'm writing a .NET Service that creates a COM object. If I run the Service as the Logged on user (everything is fine). If I run the Service as LocalSystem, everything is fine. If I run the Service as LocalService, then I get an AccessDeniedException when trying to instantiate the COM Object. I've come up with the following block to grant the necessary permissions and it appears to work correctly, but I wanted to make sure I wasn't missing something regarding the COM rules. Private Sub SetAccessToRockeyRegistry() Using reg As RegistryKey = Microsoft.Win32.Registry.ClassesRoot.OpenSubKey("CLSID\{EE0680D3-AAC3-446B-AFD7-F9DE2D3E28FB}", True) Dim sec As RegistrySecurity sec = reg.GetAccessControl Dim ar As RegistryAccessRule Dim sid As SecurityIdentifier sid = New SecurityIdentifier(WellKnownSidType.LocalServiceSid, Nothing) ar = New RegistryAccessRule(sid, RegistryRights.ReadKey Or RegistryRights.EnumerateSubKeys Or RegistryRights.QueryValues, AccessControlType.Allow) sec.AddAccessRule(ar) ar = New RegistryAccessRule(sid, RegistryRights.ReadKey Or RegistryRights.EnumerateSubKeys Or RegistryRights.QueryValues, _ InheritanceFlags.ObjectInherit Or InheritanceFlags.ContainerInherit, PropagationFlags.InheritOnly Or PropagationFlags.NoPropagateInherit, AccessControlType.Allow) sec.AddAccessRule(ar) reg.SetAccessControl(sec) End Using End Sub

• Setting HTML Text Element value

  - by Gpx

  Hi, in my C# WPF prog i´am trying to set a value of a HTML Text Element which is defined like: <input name="tbBName" type="text" id="tbBName" tabindex="1" /> What i found about it and tried is: mshtml.HTMLDocument doc = (mshtml.HTMLDocument)webBrowser1.Document; mshtml.HTMLInputTextElement tbName = (mshtml.HTMLInputTextElement)doc.getElementsByName("tbBName"); tbName.value = "Test"; But i got the exception: Unable to cast COM object of type 'System.__ComObject' to interface type 'mshtml.HTMLInputTextElement'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{3050F520-98B5-11CF-BB82-00AA00BDCE0B}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)). I know what it says but i dont know which object i can use to access the Texbox. Thanks for any answers.

• jList in Scrollpane, seeking and displaying value of selectedIndex

  - by Mech Software

  I have a JList inside a Scrollpane. If you click on the list and move the arrow keys up and down it works like you expect, you can move your selection index and display around just fine. Now, what I want to do is basically have a text box and i'm typing in the text box like "comic" and want it to seek to the index of that value. This WORKS just fine. Where the problem is when the value of the list box is below, or above the viewable area. When it is, the selected index seeks, but does not change the position of the scrollable region. However, if I press the up or down arrows and requestFocus() to the list, and move up and down it seeks to the right viewable area. What am I missing to make this happen WITHOUT changing focus. I want to be able to just type in the list all I want and have it show me what is selected. I feel i'm missing something obvious here.

• Objective C: Create arrays from first array based on value

  - by Nic Hubbard

  I have an array of strings that are comma separated such as: Steve Jobs,12,CA Fake Name,21,CA Test Name,22,CA Bill Gates,44,WA Bill Nye,21,OR I have those values in an NSScanner object so that I can loop through the values and get each comma seperated value using objectAtIndex. So, what I would like to do, is group the array items into new arrays, based on a value, in this case, State. So, from those, I need to loop through, checking which state they are in, and push those into a new array, one array per state. CA Array: Steve Jobs,12,CA Fake Name,21,CA Test Name,22,CA WA Array: Bill Gates,44,WA OR Array: Bill Nye,21,OR So in the end, I would have 3 new arrays, one for each state. Also, if there were additional states used in the first array, those should have new arrays created also. Any help would be appreciated!

• Change NSNumber value by allocating new NSNumber?

  - by Peter Hajas

  I understand that NSNumber is immutable, but I still have the need to change it in my app. I use it because it's an object, and therefore usable with @property (if I could, I would use float or CGFloat in a heartbeat, but sadly, I can't). Is there any way to just overwrite the old NSNumber instance? I'm trying this: NSNumber *zero = [[NSNumber alloc] initWithFloat:0.0]; myNSNumber = zero but this doesn't change the value. This is a simplified version of my code, as I'm changing the root view controller's parameter (I know, not MVC-friendly). Still, the changing of the value should be the same assignment, right? Should I release myNSNumber first? What should I set the @property at for myNSNumber? Thanks!

• How to make and use first object in Objective C to store sender tag

  - by dbonneville

  I started with a sample program that simply sets up a UIView with some buttons on it. Works great. I want to access the sender tag from each button and save it. My first thought was to save it to a global variable but I couldn't get it to work right. I thought the best way would be to create an object with one property and synthesize it so I can get or set it as needed. First, I created GlobalGem.h: #import <Foundation/Foundation.h> @interface GlobalGem : NSObject { int gemTag; } @property int gemTag; -(void) print; @end Then I created GlobalGem.m: #import "GlobalGem.h" @implementation GlobalGem @synthesize gemTag; -(void) print { NSLog(@"gemTag value is %i", gemTag); } @end The sample code I worked from doesn't do anything I can see in "main" where the program initializes. They just have their methods and are set up to handle IBOutlet actions. I want to use this object in the IBOutlet methods. But I don't know where to create the object. In the viewDidLoad, I tried this: GlobalGem *aGem = [[GlobalGem alloc]init]; [aGem print]; I added reference to the .h file of course. The print method works. In the nslog I get "gemTag value is 0". But now I want to use the instance aGem in some of the IBOutlet actions. For instance, if I put this same method in one of the outlet actions like this: - (IBAction)touchButton:(id)sender { [aGem print]; } ...I get a build error saying that "aGem is undeclared". Yes, I'm new to objective c and am very confused. Is the instance I created, aGem, in the viewDidLoad not accessible outside of that method? How would I create an instance of a Class that I can store a variable value that any of the IBOutlet methods can access? All the buttons need to be able to store their sender tag in the instance aGem and I'm stuck. As I mentioned earlier, I was able to write the sender tag to a global variable I declared in the UIView .h file that came with the program, but I ran into issues using it. Where am I off?

• MVC ActionLink omits action when action equals default route value

  - by rjygraham

  I have the following routes defined for my application: routes.MapRoute( "Referral", // Route name "{referralCode}", // URL with parameters new { controller = "Home", action = "Index" } // Parameter defaults ); routes.MapRoute( "Default", // Route name "{controller}/{action}", // URL with parameters new { controller = "Home", action = "Index" } // Parameter defaults ); And I'm trying to create an ActionLink to go on the Index action on my AdminController: @Html.ActionLink("admin", "Index", "Admin") However, when the view is executed the ActionLink renders as (Index action value is omitted): <a href="/Admin">admin</a> Normally this would be ok, but it's causing a collision with the "Referral" route. NOTE: If I instead use ActionLink to render a different action like "Default," the ActionLink renders correctly: <a href="/Admin/Default">admin</a> The fact that the "Default" action renders correctly leads me to believe the problem has to do with the default value specified for the route. Is there anyway to force ActionLink to render the "Index" action as well?

• Munin email notification

  I am trying to get munin to notify me via email. I have configured munin and it reports critical and warning values but no alerts are being sent neither is any script being called.

• Access violation of member of pointer object

  - by Martin Lauridsen

  So I am coding this client/server program. This code is from the client side. The client has an instance of an object mpqs_sieve *instance_; The reason I make it as a pointer is, that mpqs_sieve only has a constructor that takes 3 arguments, and I want to instantiate it at a later point in time. The client first gets some data from the server, and uses this to instantiate instance_. After this, it will request some more data, and upon receiving this (these are three coeffecients for a quadratic polynomial), it should set these in the instance_ object. However upon calling a member function of instance_, I get an access violation on one of the members of instance_ within that function call. I posted my code here: on pastebin, and I get the error on line 100. The call comes from line 71, and before that line 21. Any ideas to solve this? Thanks!

• Generic List<T> as IEnumerable<object>

  I'm trying to do cast a List to an IEnumerable, so I can verify that different lists are not null or empty: Suppose myList is a List < T . Then in the caller code I wanted: Validator.VerifyNotNullOrEmpty(myList as IEnumerable<object>, @"myList", @"ClassName.MethodName"); The valdiating code would be: public static void VerifyNotNullOrEmpty(IEnumerable<object> theIEnumerable, string theIEnumerableName, string theVerifyingPosition) { string errMsg = theVerifyingPosition + " " + theIEnumerableName; if (theIEnumerable == null) { errMsg += @" is null"; Debug.Assert(false); throw new ApplicationException(errMsg); } else if (theIEnumerable.Count() == 0) { errMsg += @" is empty"; Debug.Assert(false); throw new ApplicationException(errMsg); } } However, this doens't work. It compiles, but theIEnumerable is null! Why?

• iPhone: Activate UISlider and set its value to the location of the current touch programatically

  - by carloe

  Is it possible to set an UISlider as first responder and set its current value to the location of the current touch programatically? The way my app is set up I have a UIView container that takes up the whole screen. Inside the container I have another UIView offscreen at the bottom edge (I'll call this bottomBar). Inside the bottomBar there is a UISlider element. Right now, when the user swipes along the bottom edge of the screen the bottomBar the slider it contains slide up. What I am trying to achieve is to activate the UISlider, and set the position of the slider (the value) to the position of the users touch. Is this possible? Could someone please point me in the right direction?

• How to programmatically alpha fade a textured object in OpenGL ES 1.1 (iPhone)

  - by PewterSoft

  I've been using OpenGL ES 1.1 on the iPhone for 10 months, and in that time there is one seemingly simple task I have been unable to do: programmatically fade a textured object. To keep it simple: how can I alpha fade, under code control, a simple 2D triangle that has a texture (with alpha) applied to it. I would like to fade it in/out while it is over a scene, not a simple colored background. So far the only technique I have to do this is to create a texture with multiple pre-faded copies of the texture on it. (Yuck) As an example, I am unable to do this using Apple's GLSprite sample code as a starting point. It already textures a quad with a texture that has its own alpha. I would like to fade that object in and out.

• Extending DOMDocument and DOMNode: problem with return object

  - by Glauber Rocha

  I'm trying to extend the DOMDocument class so as to make XPath selections easier. I wrote this piece of code: class myDOMDocument extends DOMDocument { function selectNodes($xpath){ $oxpath = new DOMXPath($this); return $oxpath->query($xpath); } function selectSingleNode($xpath){ return $this->selectNodes($xpath)->item(0); } } These methods return a DOMNodeList and a DOMNode object, respectively. What I'd like to do now is to implement similar methods to the DOMNode objects. But obviously if I write a class (myDOMNode) that extends DOMNode, I won't be able to use these two extra methods on the nodes returned by myDOMDocument because they're DOMNode (and not myDOMNode) objects. I'm rather a beginner in object programming, I've tried various ideas but they all lead to a dead-end. Any hints? Thanks a lot in advance.

• Object Reference Error filling a datarow

  - by JPJedi

  This is the code: Dim dr() As DataRow = DataSet.Tables("TableName").Select("EVENTNAME = '" & name & "'") I get an "Object reference not set to an instance of an object." Error when this line is executed. It is looping through a list of selected items in a listbox. I think it has to do with how I have the datarow declared because I can look at the name and I see it ok and I also do a null check on the name before I use it. Visual Studio 2008, VB.NET. Any ideas? Yep it was a wrong table name. I guess after looking at the code for 8 hours that minor detail I just wasn't thinking to check. Thanks!

• DropDownList not updating value

  - by annelie

  Hello, I posted a question earlier but have another problem after making those changes. The previous thread can be found here: http://stackoverflow.com/questions/2700028/binding-a-dropdownlist-inside-a-detailsview Basically, I've got a dropdownlist that's dynamically populated with a list of regions. It selects the correct region when viewing the dropdown, but when I try to edit it changes the value to null. I think it might be because it doesn't know which field to update. Previously, when the dropdown list was hardcoded, I had SelectedValue='<%# Bind("region_id")%' set on the dropdown list, and when I updated it worked fine. However, I had to move the setting of the selected value into the code behind and now it just gets set to null every time I update. Here's the aspx code: <asp:DetailsView id="DetailsView1" runat="server" AutoGenerateRows="false" DataSourceID="myMySqlDataSrc" DataKeyNames="id" AutoGenerateDeleteButton="True" AutoGenerateEditButton="True" AutoGenerateInsertButton="False" OnDataBound="DetailsView1_DataBound" > <Fields> <snip> <asp:TemplateField HeaderText="Region"> <ItemTemplate><%# Eval("region_name") %></ItemTemplate> <EditItemTemplate> <asp:DropDownList ID="RegionDropdownList" runat="server"> </asp:DropDownList> </EditItemTemplate> </asp:TemplateField> </Fields> </asp:DetailsView> And here's the code behind: protected void DetailsView1_DataBound(object sender, EventArgs e) { ArrayList regionsList = BPBusiness.getRegions(); if (DetailsView1.CurrentMode == DetailsViewMode.Edit) { DropDownList ddlRegions = (DropDownList)DetailsView1.FindControl("RegionDropdownList"); if (ddlRegions != null) { ddlRegions.DataSource = regionsList; ddlRegions.DataValueField = "Value"; ddlRegions.DataTextField = "Text"; ddlRegions.DataBind(); if (ddlRegions.Items.Contains(ddlRegions.Items.FindByValue(objBusiness.iRegionID.ToString()))) { ddlRegions.SelectedIndex = ddlRegions.Items.IndexOf(ddlRegions.Items.FindByValue(objBusiness.iRegionID.ToString())); } } } } EDIT: The database is MySql, and the update statement looks like this: myMySqlDataSrc.UpdateCommand = "UPDATE myTable SET business_name = ?, addr_line_1 = ?, addr_line_2 = ?, addr_line_3 = ?, postcode = ?, county = ?, town_city = ?, tl_url = ?, customer_id = ?, region_id = ?, description = ?, approval_status = ?, tl_user_name = ?, phone = ?, uploaders_own = ? WHERE id = ?"; Thanks, Annelie
