  • How to make a wxFrame behave like a modal wxDialog object

    - by dagorym
    Is is possible to make a wxFrame object behave like a modal dialog box in that the window creating the wxFrame object stops execution until the wxFrame object exits? I'm working on a small game and have run into the following problem. I have a main program window that hosts the main application (strategic portion). Occasionally, I need to transfer control to a second window for resolution of part of the game (tactical portion). While in the second window, I want the processing in the first window to stop and wait for completion of the work being done in the second window. Normally a modal dialog would do the trick but I want the new window to have some functionality that I can't seem to get with a wxDialog, namely a status bar at the bottom and the ability to resize/maximize/minimize the window (this should be possible but doesn't work, see this question How to get the minimize and maximize buttons to appear on a wxDialog object). As an addition note, I want the second window's functionality needs to stay completely decoupled from the primary window as it will be spun off into a separate program eventually. Has anyone done this or have any suggestions?

  • Looks like COM object is created, but JScript fails to get a reference

    - by damix911
    I'm using the following code to create a COM component that I have developed and registered. var mycom = new ActiveXObject("Mirabilis.ComponentServices.1"); mycom.SetFirstNumber(5); mycom.SetSecondNumber(3); The first line runs fine, while if I alter the ProgID (that is, the string passed to ActiveXObject) I get the message Automation server can't create object. This suggests that at least the basics of the registration mechanism are working properly. I integrated some logging calls into the DLL. When I run the script I get the proof into the log file that both this call to QueryInterface: STDAPI DllGetClassObject( const CLSID &clsid, const IID &iid, void **ppv) { ... CAddFactory *pAddFact = new CAddFactory; ... HRESULT hr = pAddFact->QueryInterface(iid, ppv); if (hr == S_OK) writeToLogFile("Class QueryInterface returned S_OK"); else writeToLogFile("Class QueryInterface failed"); return hr; ... } and this one: HRESULT __stdcall CAddFactory::CreateInstance( IUnknown *pUnknownOuter, const IID &iid, void **ppv) { ... CAddObj *pObject = new CAddObj; ... HRESULT hr = pObject->QueryInterface(iid, ppv); if (hr == S_OK) writeToLogFile("Object QueryInterface returned S_OK"); else writeToLogFile("Object QueryInterface failed"); return hr; ... } return S_OK. However, when JScript gets to line 3 of the script, I get the following error message: 'mycom' is null or not an object Why is this happening? It looks like JScript should be able to obtain a reference. Some attempts I made I tried to return S_FALSE from DllCanUnloadNow to be sure that the DLL will not be unloaded, just in case, but with no luck.

  • Variable reference problem when loading an object from a file in Java

    - by Snail
    I have a problem with the reference of a variable when loading a saved serialized object from a data file. All the variables referencing to the same object doesn't seem to update on the change. I've made a code snipped below that illustrates the problem. Tournament test1 = new Tournament(); Tournament test2 = test1; try { FileInputStream fis = new FileInputStream("test.out"); ObjectInputStream in = new ObjectInputStream(fis); test1 = (Tournament) in.readObject(); in.close(); } catch (IOException ex){ Logger.getLogger(Frame.class.getName()).log(Level.SEVERE, null, ex); } catch (ClassNotFoundException ex){ Logger.getLogger(Frame.class.getName()).log(Level.SEVERE, null, ex); } System.out.println("test1: " + test1); System.out.println("test2: " + test2); After this code is ran test1 and test2 doesn't reference to the same object anymore. To my knowledge they should do that since in the declaration of test2 makes it a reference to test1. When test1 is updated test2 should reflect the change and return the new object when called in the code. Am I missing something essential here or have I been misstaught about how the variable references in Java works?

  • CarrierWave and nested forms saving empty image object if photo :title is included in form

    - by Wasabi Developer
    I'm after some advice in regards to handling nested form data and I would be ever so grateful for any insights. The trouble is I'm not 100% sure why I require the following code in my model accepts_nested_attributes_for :holiday_image, allow_destroy: true, :reject_if => lambda { |a| a[:title].blank? } If I don't understand why I require to tact on on my accepts_nested_attributes_for association: :reject_if => lambda { |a| a[:title].blank? } If I remove this :reject_if lambda, it will save a blank holiday photo object in the database. I presume because it takes the :title field from the form as an empty string? I guess my question is, am I doing this right or is there a better way of this this within nested forms if I want to extend my HolidayImage model to include more strings like description, notes? Sorry If I can't be more succinct. My simple holiday app. # holiday.rb class Holiday < ActiveRecord::Base has_many :holiday_image accepts_nested_attributes_for :holiday_image, allow_destroy: true, :reject_if => lambda { |a| a[:title].blank? } attr_accessible :name, :content, :holiday_image_attributes end I'm using CarrierWave for image uploads. # holiday_image.rb class HolidayImage < ActiveRecord::Base belongs_to :holiday attr_accessible :holiday_id, :image, :title mount_uploader :image, ImageUploader end Inside my _form partial there is a field_for block <h3>Photo gallery</h3> <%= f.fields_for :holiday_image do |holiday_image| %> <% if holiday_image.object.new_record? %> <%= holiday_image.label :title, "Image Title" %> <%= holiday_image.text_field :title %> <%= holiday_image.file_field :image %> <% else %> Title: <%= holiday_image.object.title %> <%= image_tag(holiday_image.object.image.url(:thumb)) %> Tick to delete: <%= holiday_image.check_box :_destroy %> <% end %> Thanks again for your patience.

  • Remove pointer object whose reference is mantained in three different lists

    - by brainydexter
    I am not sure how to approach this problem: 'Player' class mantains a list of Bullet* objects: class Player { protected: std::list< Bullet* > m_pBullet_list; } When the player fires a Bullet, it is added to this list. Also, inside the constructor of bullet, a reference of the same object is updated in CollisionMgr, where CollisionMgr also mantains a list of Bullet*. Bullet::Bullet(GameGL*a_pGameGL, Player*a_pPlayer) : GameObject( a_pGameGL ) { m_pPlayer = a_pPlayer; m_pGameGL->GetCollisionMgr()->AddBullet(this); } class CollisionMgr { void AddBullet(Bullet* a_pBullet); protected: std::list< Bullet*> m_BulletPList; } In CollisionMgr.Update(); based on some conditions, I populate class Cell which again contain a list of Bullet*. Finally, certain conditions qualify a Bullet to be deleted. Now, these conditions are tested upon while iterating through a Cell's list. So, if I have to delete the Bullet object, from all these places, how should I do it so that there are no more dangling references to it? std::list< Bullet*>::iterator bullet_it; for( bullet_it = (a_pCell->m_BulletPList).begin(); bullet_it != (a_pCell->m_BulletPList).end(); bullet_it++) { bool l_Bullet_trash = false; Bullet* bullet1 = *bullet_it; // conditions would set this to true if ( l_Bullet_Trash ) // TrashBullet( bullet1 ); continue; } Also, I was reading about list::remove, and it mentions that it calls the destructor of the object we are trying to delete. Given this info, if I delete from one list, the object does not exist, but the list would still contain a reference to it..How do I handle all these problems ? Can someone please help me here ? Thanks PS: If you want me to post more code or provide explanation, please do let me know.

  • How to get application context path in spring-ws?

    - by Dhaliwal
    I am using Spring-WS to create a webservice. In my project, I have created a Helper class to reads sample response and request xml file which are located in my /src/main/resource folder. When I am unit-testing my webservice application 'locally', I use the System.getProperty("user.dir") to get the application context folder. The following is a method that I created in the Helper class to help me retrieve the file that I am interested in my resource folder. public static File getFileFromResources(String filename) { System.out.println("Getting file from resource folder"); File request = null; String curDir = System.getProperty("user.dir"); String contextpath = "C:\\src\\main\\resources\\"; request = new File(curDir + contextpath + filename); return request; } However, after 'publishing' the compiled WAR file to the ../webapps folder to the Apache Tomcat directory, I realise that System.getProperty("user.dir") no longer returns my application context path. Instead, it is returning the Apache Tomcat root directory as shown C:\Program Files\Apache Software Foundation\Tomcat 6.0\src\main\resources\SampleClientFile I cant seem to find any information about getting the root folder of my webservice. I have seen examples on Spring web application where I can retrieve the context path by using the following : request.getSession().getServletContext().getContextPath() But in this case, I am using a Spring web application where there is a servlet context in the request. But the Spring-WS, my entry point is an endpoint. How can I get the context path of my webservice application. I am expecting a context path of something like C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\clientWebService\WEB-INF\classes Could someone suggest a way to achieve this?

  • javascript: "Object doesn't support this property or method" when ActiveX object called.

    - by agnieszka
    I've got simple html on Login.aspx with an ActiveX object: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <head><title></title> <script language="javaScript" type="text/javascript"> function getUserInfo() { var userInfo = MyActiveX.GetInfo(); form1.info.value = userInfo; form1.submit(); } </script> </head> <body onload="javascript:getUserInfo()"> <object id="MyActiveX" name="MyActiveX" codebase="MyActiveX.cab" classid="CLSID:C63E6630-047E-4C31-H457-425C8412JAI25"></object> <form name="form1" method="post" action="Login.aspx"> <input type="hidden" id="info" name="info" value="" /> </form> </body> </html> The code works perfectly fine on my machine (edit: hosted and run), it does't work on the other: there is an error "Object doesn't support this property or method" in the first line of javascript function. The cab file is in the same folder as the page file. I don't know javascript at all and have no idea why is the problem occuring. Googling didn't help. Do you ave any idea? Edit: on both machines IE was used and activex was enabled. Edit2: I also added if (document.MyActiveX) at the beggining of the function and I still get error in the same line of code - I mean it looks like document.MyActiveX is true but calling the method still fails

  • Connecting to an RMI object without registry

    - by Mark Probst
    I think I need to connect to a remote RMI object without going through the registry, but I don't know how. My situation is this: I'm implementing a simple job distribution service which consists of one distributor and multiple workers. The distributor has a registered RMI object to which clients connect to send jobs, and workers connect to accept jobs. Unfortunately the distributor and worker hosts are behind a firewall. To get to the distributor host I am tunneling two ports (one for the registry, one for the distributor object) via SSH, so I can get to the registry and the distributor from outside the firewall. To make that work I have to set "-Djava.rmi.server.hostname=localhost" on the distributor JVM so that the clients connect to their local, tunneled port, instead of the port on the actual distributor host, which is blocked. This creates a problem for the workers, though, because they need to connect to the distributor directly, but because of the "localhost" redirection they behave like clients and try to connect to a port on their own host, which is not available, because I'm not tunneling on the workers (it is impractical). Now, if I could connect to a remote object directly by giving the hostname and port, I could do away both with the registry on the distributor and the "localhost" hack, and make the workers connect properly. How do I do that? Or is there a different solution to this problem?

  • WCF: Exposed Object Model - stuck in a loop

    - by Mark
    Hi I'm working on a pretty big WSSF project. I have a normal object model in the business layer. Eg a customer has an orders collection property, when this is accessed then it loads from the data layer (lazy loading). An order has a productCollection property etc etc.. Now the bit I'm finding tricky is exposing this via WCF. I want to export a collection of orders. The client app will also need information about the customers. Using the WSSF data contract designer I have set it up so that customers have a property called "order collection". This is fine if you have a customer object and would like to look at the orders but if you have an order object there is no customer property so it doesn't work going up the hierarchy. I've tried adding a customer property to the orders object but then the code gets stuck in a loop when it loads the data contracts up. This is because it doesn't load on demand like in the business layer. I need to load all properties up before the objects can be sent out via WCF. It ends up loading an order, then the customer for that order, then the orders for that customer, then the customer for that order etc etc... I'm sure I've got all this wrong. Help!!

  • Best way to transfer an Entity Framework object over the web and back via JSON

    - by AVH
    I've got some MVC code that serializes an EF 3.5 object into an anonymous type for return as a JSON result to an AJAX call on my page. The hurdle I have is that when I send the object back to the server via JSON, (and let the ModelBinder deserialize it for me into my EF type), I have to update it in my Entity Framework context manually. Or at least that's what I'm doing now. It has no EntityKey, so attaching it fails. I end up having to look up the old object and update it property by property. Any ideas around this? Is the solution to pass the EntityKey around with my object? Here's what I have: public void Update(Album album) { using (var db = new BandSitesMasterEntities()) { var albumToUpdate = db.Album.First(x => x.ID == album.ID); albumToUpdate.AlbumTitle = album.AlbumTitle; albumToUpdate.Description = album.Description; albumToUpdate.ReleaseYear = album.ReleaseYear; albumToUpdate.ImageURL = album.ImageURL; albumToUpdate.OtherURL = album.OtherURL; db.SaveChanges(); } } And here's what I'd like to do, or something similar: public void Update(Album album) { using (var db = new BandSitesMasterEntities()) { db.Attach(album) db.SaveChanges(); } }

  • How to print each object in a collection in a separate page in Silverlight

    - by Ash
    I would like to know if its possible to print each object in a collection in separate pages using Silverlight printing API. Suppose I have a class Label public class Label { public string Address { get; set; } public string Country { get; set; } public string Name { get; set; } public string Town { get; set; } } I can use print API and print like this. private PrintDocument pd; private void PrintButton_Click(object sender, RoutedEventArgs e) { pd.Print("Test Print"); } private void pd_PrintPage(object sender, PrintPageEventArgs e) { Label labelToPrint = new Label() { Name = "Fake Name", Address = "Fake Address", Country = "Fake Country", Town = "Town" }; var printpage = new LabelPrint(); printpage.DataContext = new LabelPrintViewModel(labelToPrint); e.PageVisual = printpage; } LabelPrint Xaml <StackPanel x:Name="LayoutRoot" VerticalAlignment="Center" HorizontalAlignment="Center"> <TextBlock Text="{Binding Name}" /> <TextBlock Text="{Binding Address}" /> <TextBlock Text="{Binding Town}" /> <TextBlock Text="{Binding Country}" /> </StackPanel> Now, say I've a collection of Label objects, List<Label> labels = new List<Label>() { labelToPrint, labelToPrint, labelToPrint, labelToPrint }; How can I print each object in the list in separate pages ? Thanks for any suggestions ..

  • "Finding" an object instance of a known class?

    - by Sean C
    My first post here (anywhere for that matter!), re. Cocoa/Obj-C (I'm NOT up to speed on either, please be patient!). I hope I haven't missed the answer already, I did try to find it. I'm an old-school procedural dog (haven't done any programming since the mid 80's, so I probably just can't even learn new tricks), but OOP has my head spinning! My question is: is there any means at all to "discover/find/identify" an instance of an object of a known class, given that some OTHER unknown process instantiated it? eg. somthing that would accomplish this scenario: (id) anObj = [someTarget getMostRecentInstanceOf:[aKnownClass class]]; for that matter, "getAnyInstance" or "getAllInstances" might do the trick too. Background: I'm trying to write a plugin for a commercial application, so much of the heavy lifting is being done by the app, behind the scenes. I have the SDK & header files, I know what class the object is, and what method I need to call (it has only instance methods), I just can't identify the object for targetting. I've spent untold hours and days going over Apples documentation, tutorials and lots of example/sample code on the web (including here at Stack Overflow), and come up empty. Seems that everything requires a known target object to work, and I just don't have one. Since I may not be expressing my problem as clearly as needed, I've put up a web page, with diagram & working sample pages to illustrate: http://www.nulltime.com/svtest/index.html Any help or guidance will be appreciated! Thanks.

  • JS: Object itteration fails

    - by Newbie
    Hello! In my JS, I have an object called box_object. It looks like this: ({ id:"3", text:"this is a box object", connection_parent:["1", "2"], connection_child:["5", "6"], connectiondata_child:{ 0:{id:"5", linepoint:"bottom"}, 1:{id:"6", linepoint:"bottom"}}, connectiondata_parent:{ 0:{id:"1", linepoint:"top"}, 1:{id:"2", linepoint:"top"}} }) Now, I want to add some position values to box_object.connectiondata_parent. Using jQuery I can use the .each() method. So I tried it, but it failed. In my function I do the following: $(box_object.connectiondata_parent).each(function(it, obj){ if(typeof(obj[it]) != "undefined" && obj[it].linepoint == "top"){ var point_position_top = new Object(); point_position_top.left = startingpoint_left; point_position_top.top = startingpoint_top; obj[it].position = point_position_top; }else if(typeof(obj[it]) != "undefined" && obj[it].linepoint == "bottom"){ var point_position_bottom = new Object(); point_position_bottom.left = startingpoint_left; point_position_bottom.top = startingpoint_bottom; obj[it].position = point_position_bottom; }else{} }); After the function my box_object looks like this: ({ id:"3", text:"this is third box", connection_parent:["1", "2"], connection_child:["5", "6"], connectiondata_child:{ 0:{id:"5", linepoint:"bottom"}, 1:{id:"6", linepoint:"bottom"}}, connectiondata_parent:{ 0:{id:"1", linepoint:"top", position:{left:500, top:104}}, 1:{id:"2", linepoint:"top"}} }) It seems it only writes the values to the first "value". Any Ideas why?

  • object construct a class of objects in java

    - by Mgccl
    There is a super class, A, and there are many subclasses, B,C,D... people can write more subclasses. Each of the class have the method dostuff(), each is different in some way. I want an object that constructs any object that belong to A or any of it's subclass. For example I can pass the name of the subclass, or a object of that class, and it will construct another object of the class. Of course I can write A construct(A var){ stuff = var.dostuff(); domorestuff(stuff) return new A(stuff); } B construct(B var){ stuff = var.dostuff(); domorestuff(stuff) return new B(stuff); } C construct(C var){ stuff = var.dostuff(); domorestuff(stuff) return new C(stuff); } but this is not efficient. I have to write a few new lines every time I make a new subclass. It seems I can't use generics either. Because I can't use dostuff() on objects not in any of the subclass of A. What should I do in this situation?

  • How to marshal an object and its content (also objects)

    - by Waldo Spek
    I have a question for which I suspect the answer is a bit complex. At this moment I am programming a DLL (class library) in C#. This DLL uses a 3rd party library and therefore deals with 3rd party objects of which I do not have the source code. Now I am planning to create another DLL, which is going to be used in a later stadium in my application. This second DLL should use the 3rd party objects (with corresponding object states) created by the first DLL. Luckily the 3rd party objects extend the MarshalByRefObject class. I can marshal the objects using System.Runtime.Remoting.Marshal(...). I then serialize the objects using a BinaryFormatter and store the objects as a byte[] array. All goes well. I can deserialize and unmarshal in a the opposite way and end up with my original 3rd party objects...so it appears... Nevertheless, when calling methods on my 3rd party deserialized objects I get object internal exceptions. Normally these methods return other 3rd party objects, but (obviously - I guess) now these objects are missing because they weren't serialized. Now my global question: how would I go about marshalling/serializing all the objects which my 3rd party objects reference...and cascade down the "reference tree" to obtain a full and complete serialized object? Right now my guess is to preprocess: obtain all the objects and build my own custom object and serialize it. But I'm hoping there is some other way...

  • rbind.zoo doesn't seem create consistent zoo object

    - by a-or-b
    I want to rbind.zoo two zoo object together. When I was testing I came across the following issue(?)... Note: The below is an example, there is clearly no point to it apart from being illustrative. I have an zoo object, call it, 'X'. I want to break it into two parts and then rbind.zoo them together. When I compare it to the original object then all.equal gives differences. It appears that the '$class' attribute differs, but I can't see how or why. Is I make these xts objects then the all.equal works as expected. i.e. ..... X.date <- as.POSIXct(paste("2003-", rep(1:4, 4:1), "-", sample(1:28, 10, replace = TRUE), sep = "")) X <- zoo(matrix(rnorm(24), ncol = 2), X.date) a <- X[c(1:3), ] # first 3 elements b <- X[c(4:6), ] # second 3 elements c <- rbind.zoo(a, b) # rbind into an object of 6 elements d <- X[c(1:6), ] # all 6 elements all.equal(c, d) # are they equal? ~~~~ all.equal gives me the following difference: "Attributes: < Component 3: Attributes: < Length mismatch: comparison on first 1 components "

  • How to output multiple rows from an SQL query using the mysqli object

    - by Jonathan
    Assuming that the mysqli object is already instantiatied (and connected) with the global variable $mysql, here is the code I am trying to work with. class Listing { private $mysql; function getListingInfo($l_id = "", $category = "", $subcategory = "", $username = "", $status = "active") { $condition = "`status` = '$status'"; if (!empty($l_id)) $condition .= "AND `L_ID` = '$l_id'"; if (!empty($category)) $condition .= "AND `category` = '$category'"; if (!empty($subcategory)) $condition .= "AND `subcategory` = '$subcategory'"; if (!empty($username)) $condition .= "AND `username` = '$username'"; $result = $this->mysql->query("SELECT * FROM listing WHERE $condition") or die('Error fetching values'); $this->listing = $result->fetch_array() or die('could not create object'); foreach ($this->listing as $key => $value) : $info[$key] = stripslashes(html_entity_decode($value)); endforeach; return $info; } } there are several hundred listings in the db and when I call $result-fetch_array() it places in an array the first row in the db. however when I try to call the object, I can't seem to access more than the first row. for instance: $listing_row = new Listing; while ($listing = $listing_row-getListingInfo()) { echo $listing[0]; } this outputs an infinite loop of the same row in the db. Why does it not advance to the next row? if I move the code: $this->listing = $result->fetch_array() or die('could not create object'); foreach ($this->listing as $key => $value) : $info[$key] = stripslashes(html_entity_decode($value)); endforeach; if I move this outside the class, it works exactly as expected outputting a row at a time while looping through the while statement. Is there a way to write this so that I can keep the fetch_array() call in the class and still loop through the records?

  • Determining an object's variable name dynamically?

    - by ZenBlender
    Let's say I have some objects: ArrayList<SomeObject> list = new ArrayList<SomeObject>(); SomeObject A = new SomeObject(); SomeObject B = new SomeObject(); SomeObject C = new SomeObject(); SomeObject D = new SomeObject(); These constructors automatically add each object to the ArrayList so I can iterate over them but still maintain the variable names for direct access: public SomeObject(){ // init stuff here list.add(this); } But then, let's say I want to output some debug info, and iterate through list and print out the NAME of each object? How can I do that? Essentially, when "SomeObject A = new SomeObject();" is executed, I want to use reflection (if possible) to determine that this variable's name is "A" (a String) and either store that in the object when the constructor executes, or determine it dynamically through reflection when referencing this object with the variable named "A". Does that make sense? How can I do this? Thanks!

  • Issue pushing object into an array JS

    I'm having an issue placing an object into my array in javascript. This is the code: $('.confirmBtn').click(function(){ //Get reference to the Value in the Text area var comment = $("#comments").val(); //Create Object var orderComment = { 'comment' : comment }; //Add Object to the Array productArray.push(orderComment); //update cookie $.cookie('order_cookie', JSON.stringify(productArray), { expires: 1, path: '/' }); }); However when I print the array this is the output: Array ( [0] => Array ( [stockCode] => CBL202659/A [quantity] => 8 ) [1] => Array ( [stockCode] => CBL201764 [quantity] => 6 ) [2] => TEST TEST ) I would like it to look like this: Array ( [0] => Array ( [stockCode] => CBL202659/A [quantity] => 8 ) [1] => Array ( [stockCode] => CBL201764 [quantity] => 6 ) [2] Array( [comment] => TEST TEST ) I added products to the array in a similar way and it worked fine: var productArray = []; // Will hold order Items $(".orderBtn").click(function(event){ //Check to ensure quantity > 0 if(quantity == 0){ console.log("Quantity must be greater than 0") }else{//It is so continue //Show the order Box $(".order-alert").show(); event.preventDefault(); //Get reference to the product clicked var stockCode = $(this).closest('li').find('.stock_code').html(); //Get reference to the quantity selected var quantity = $(this).closest('li').find('.order_amount').val(); //Order Item (contains stockCode and Quantity) - Can add whatever data I like here var orderItem = { 'stockCode' : stockCode, 'quantity' : quantity }; //Check if cookie exists if($.cookie('order_cookie') === undefined){ console.log("Creating new cookie"); //Add object to the Array productArray.push(orderItem);

  • overload == (and != , of course) operator, can I bypass == to determine whether the object is null

    - by LLS
    Hello, when I try to overload operator == and != in C#, and override Equal as recommended, I found I have no way to distinguish a normal object and null. For example, I defined a class Complex. public static bool operator ==(Complex lhs, Complex rhs) { return lhs.Equals(rhs); } public static bool operator !=(Complex lhs, Complex rhs) { return !lhs.Equals(rhs); } public override bool Equals(object obj) { if (obj is Complex) { return (((Complex)obj).Real == this.Real && ((Complex)obj).Imaginary == this.Imaginary); } else { return false; } } But when I want to use if (temp == null) When temp is really null, some exception happens. And I can't use == to determine whether the lhs is null, which will cause infinite loop. What should I do in this situation. One way I can think of is to us some thing like Class.Equal(object, object) (if it exists) to bypass the == when I do the check. What is the normal way to solve the problem?

    I am going to be using some DSQUERY/DSMOVE scripts to clean up my AD Domin. One option is to move inactive objects to a OU that has restrictive GPOs applied to it. Something like: DSQUERY computer -inactive 10 | DSMOVE -newparent <distinguished name of target OU> My question is what value defines an object, both user and computer, as "inactive" for a period of time? Is it the last time a computer was logged on to for computer accounts, and for users is it the last time that the user account logged on to a computer? But what if, say for example, I had a web server that wasn't rebooted and or logged into for a couple of months but remain powered on and functioning as normal, would it be defined as "inactive" where as technically it's still serving web pages and so on? Thanks for the help!

  • Server 2003 - Default installation of SharePoint throws javascript error 'undefined' is null or not an object

    - by Chris
    I have been handed a server that has a fresh installation of small business server 2003. SharePoint has been installed, and it is a completely fresh copy (no changes made) I know for a fact that everything was paid for so this isn't some dodgy copy. When I try to click any option in any of the floating menu's in IE 8, the browser asks me if I want to debug .. Error: 'undefined' is null or not an object for example, I got to Projects - and click on the sample project, then click delete on the floating menu that pops up and the error appears. This is brand new, I cannot believe I am having this problem! Has anyone come across this, is it an old problem with easy fix? All windows updates installed - see no updates for sharepoint? EDIT: This is WSS2 so I am going to upgrade to WSS3... http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=14117 http://www.techrepublic.com/article/installing-windows-sharepoint-services-30-on-windows-server-2003/6176833 Hopefully this will resolve the problem

  • 'Object variable or With block variable not set' error when setting a range in VBA

    - by David Gard
    I have a function that creates a Pivot Table, but I am getting an error when I try to set a range that will be merged and have a title added to it. In the below code, pivot_title_range is a 'String' variable, and is optional when calling the funtion. title_range is a 'Range' variable. Both lines that set the range (whether or not the users declares pivot_title_range) cause the same error. If pivot_title_range = "" Then title_range = ActiveSheet.Range("B3:E4") Else title_range = ActiveSheet.Range(pivot_title_range) End If Here is the error that I am getting - Run-time error '91': Object variable or With block variable not set If required, here is a Pastebin of the full function - http://pastebin.com/L711jayc. The offending code starts on line 160. Is anybody able to tell me what I am doing wrong? Thanks.
