  • Passing Objects between different files

    - by user309779
    Typically, if I want to pass an object to an instance of something I would do it like so... Listing 1 File 1: public class SomeClass { // Some Properties public SomeClass() { public int ID { get { return mID; } set { mID = value; } } public string Name { set { mName = value; } get { return mName; } } } } public class SomeOtherClass { // Method 1 private void Method1(int one, int two) { SomeClass USER; // Create an instance Squid RsP = new Squid(); RsP.sqdReadUserConf(USER); // Able to pass 'USER' to class method in different file. } } In this example, I was not able to use the above approach. Probably because the above example passes an object between classes. Whereas, below, things are defined in a single class. I had to use some extra steps (trial & error) to get things to work. I am not sure what I did here or what its called. Is it good programming practice? Or is there is an easier way to do this (like above). Listing 2 File 1: private void SomeClass1 { [snip] TCOpt_fM.AutoUpdate = optAutoUpdate.Checked; TCOpt_fM.WhiteList = optWhiteList.Checked; TCOpt_fM.BlackList = optBlackList.Checked; [snip] private TCOpt TCOpt_fM; TCOpt_fM.SaveOptions(TCOpt_fM); } File 2: public class TCOpt: { public TCOpt OPTIONS; [snip] private bool mAutoUpdate = true; private bool mWhiteList = true; private bool mBlackList = true; [snip] public bool AutoUpdate { get { return mAutoUpdate; } set { mAutoUpdate = value; } } public bool WhiteList { get { return mWhiteList; } set { mWhiteList = value; } } public bool BlackList { get { return mBlackList; } set { mBlackList = value; } } [snip] public bool SaveOptions(TCOpt OPTIONS) { [snip] Some things being written out to a file here [snip] Squid soSwGP = new Squid(); soSgP.sqdWriteGlobalConf(OPTIONS); } } File 3: public class SomeClass2 { public bool sqdWriteGlobalConf(TCOpt OPTIONS) { Console.WriteLine(OPTIONS.WhiteSites); // Nothing prints here Console.WriteLine(OPTIONS.BlackSites); // Or here } } Thanks in advance, XO

  • Tool for debugging KVO/Bindings in Cocoa

    - by Raphael Sebbe
    Is there any tool to log current observers of a given object, in the spirit of what "gdb info gc-roots" does? I found "gdb info gc-references" could do that (sort of) as a by-product of its original purpose, but that won't work with non garbage collected apps. Thanks!

  • KVO on the "windows" value of UIApplication?

    - by Ariel Malka
    The following is not working: [[UIApplication sharedApplication] addObserver:self forKeyPath:@"windows" options:(NSKeyValueObservingOptionNew|NSKeyValueObservingOptionOld) context:NULL]; Together with that, on the Observer side: - (void) observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context { NSLog(@"never reached!"); } Any clues? N.B. My uber-goal is to get a notification when a (system-generated) UIAlertView is shown.

  • Linq to sql C# updating reference Tables

    - by Laurence Burke
    ok reclarification I am adding a new address and I know the structure as AddressID = PK and all other entities are non nullable. Now on insert of a new row the addrID Pk is autogened and I am wondering if I would have to get that to create a new row in the referencing table or does that automatically get generated also. also I want to be able to repopulate the dropdownlist that lists the current employee's addresses with the newly created address. static uint _curEmpID; protected void btnAdd_Click(object sender, EventArgs e) { if (txtZip.Text != "" && txtAdd1.Text != "" && txtCity.Text != "") { TestDataClassDataContext dc = new TestDataClassDataContext(); Address addr = new Address() { AddressLine1 = txtAdd1.Text, AddressLine2 = txtAdd2.Text, City = txtCity.Text, PostalCode = txtZip.Text, StateProvinceID = Convert.ToInt32(ddlState.SelectedValue) }; dc.Addresses.InsertOnSubmit(addr); lblSuccess.Visible = true; lblErrMsg.Visible = false; dc.SubmitChanges(); // // TODO: add reference from new address to CurEmp Table // SetAddrList(); } else { lblErrMsg.Text = "Invalid Input"; lblErrMsg.Visible = true; } } protected void ddlAddList_SelectedIndexChanged(object sender, EventArgs e) { lblErrMsg.Visible = false; lblSuccess.Visible = false; TestDataClassDataContext dc = new TestDataClassDataContext(); dc.ObjectTrackingEnabled = false; if (ddlAddList.SelectedValue != "-1") { var addr = (from a in dc.Addresses where a.AddressID == Convert.ToInt32(ddlAddList.SelectedValue) select a).FirstOrDefault(); txtAdd1.Text = addr.AddressLine1; txtAdd2.Text = addr.AddressLine2; txtCity.Text = addr.City; txtZip.Text = addr.PostalCode; ddlState.SelectedValue = addr.StateProvinceID.ToString(); btnSubmit.Visible = true; btnAdd.Visible = false; } else { txtAdd1.Text = ""; txtAdd2.Text = ""; txtCity.Text = ""; txtZip.Text = ""; btnAdd.Visible = true; btnSubmit.Visible = false; } } protected void SetAddrList() { TestDataClassDataContext dc = new TestDataClassDataContext(); dc.ObjectTrackingEnabled = false; var addList = from addr in dc.Addresses from eaddr in dc.EmployeeAddresses where eaddr.EmployeeID == _curEmpID && addr.AddressID == eaddr.AddressID select new { AddValue = addr.AddressID, AddText = addr.AddressID, }; ddlAddList.DataSource = addList; ddlAddList.DataValueField = "AddValue"; ddlAddList.DataTextField = "AddText"; ddlAddList.DataBind(); ddlAddList.Items.Add(new ListItem("<Add Address>", "-1")); } OK I am hoping that I did not include too much code. I would really appreciate any other comments about I could otherwise improve this code in any other ways also.

  • Accessing the buffered request body in HttpWebRequest?

    - by Greg Beech
    By default HttpWebRequest has AllowWriteStreamBuffering set to true, which means that all data written to the request stream is buffered inside the object. I'd like to access this buffer of data after it has been written, but can't seem to find any way to do so. I'm happy for it to fail if AllowWriteStreamBuffering is false. Is there any way to do this, or is it not exposed anywhere?

  • Speeding up templates in GAE-Py by aggregating RPC calls

    - by Sudhir Jonathan
    Here's my problem: class City(Model): name = StringProperty() class Author(Model): name = StringProperty() city = ReferenceProperty(City) class Post(Model): author = ReferenceProperty(Author) content = StringProperty() The code isn't important... its this django template: {% for post in posts %} <div>{{post.content}}</div> <div>by {{post.author.name}} from {{post.author.city.name}}</div> {% endfor %} Now lets say I get the first 100 posts using Post.all().fetch(limit=100), and pass this list to the template - what happens? It makes 200 more datastore gets - 100 to get each author, 100 to get each author's city. This is perfectly understandable, actually, since the post only has a reference to the author, and the author only has a reference to the city. The __get__ accessor on the post.author and author.city objects transparently do a get and pull the data back (See this question). Some ways around this are Use Post.author.get_value_for_datastore(post) to collect the author keys (see the link above), and then do a batch get to get them all - the trouble here is that we need to re-construct a template data object... something which needs extra code and maintenance for each model and handler. Write an accessor, say cached_author, that checks memcache for the author first and returns that - the problem here is that post.cached_author is going to be called 100 times, which could probably mean 100 memcache calls. Hold a static key to object map (and refresh it maybe once in five minutes) if the data doesn't have to be very up to date. The cached_author accessor can then just refer to this map. All these ideas need extra code and maintenance, and they're not very transparent. What if we could do @prefetch def render_template(path, data) template.render(path, data) Turns out we can... hooks and Guido's instrumentation module both prove it. If the @prefetch method wraps a template render by capturing which keys are requested we can (atleast to one level of depth) capture which keys are being requested, return mock objects, and do a batch get on them. This could be repeated for all depth levels, till no new keys are being requested. The final render could intercept the gets and return the objects from a map. This would change a total of 200 gets into 3, transparently and without any extra code. Not to mention greatly cut down the need for memcache and help in situations where memcache can't be used. Trouble is I don't know how to do it (yet). Before I start trying, has anyone else done this? Or does anyone want to help? Or do you see a massive flaw in the plan?

    I have a .SWF email submit form.

  • Can I call make runtime decided method calls in Java?

    - by Catalin Marin
    I know there is an invoke function that does the stuff, I am overall interested in the "correctness" of using such a behavior. My issue is this: I have a Service Object witch contains methods which I consider services. What I want to do is alter the behavior of those services without later intrusion. For example: class MyService { public ServiceResponse ServeMeDonuts() { do stuff... return new ServiceResponse(); } after 2 months I find out that I need to offer the same service to a new client app and I also need to do certain extra stuff like setting a flag, or make or updating certain data, or encode the response differently. What I can do is pop it up and throw down some IFs. In my opinion this is not good as it means interaction with tested code and may result in un wanted behaviour for the previous service clients. So I come and add something to my registry telling the system that the "NewClient" has a different behavior. So I'll do something like this: public interface Behavior { public void preExecute(); public void postExecute(); } public class BehaviorOfMyService implements Behavior{ String method; String clientType; public void BehaviorOfMyService(String method,String clientType) { this.method = method; this.clientType = clientType; } public void preExecute() { Method preCall = this.getClass().getMethod("pre" + this.method + this.clientType); if(preCall != null) { return preCall.invoke(); } return false; } ...same for postExecute(); public void preServeMeDonutsNewClient() { do the stuff... } } when the system will do something like this if(registrySaysThereIs different behavior set for this ServiceObject) { Class toBeCalled = Class.forName("BehaviorOf" + usedServiceObjectName); Object instance = toBeCalled.getConstructor().newInstance(method,client); instance.preExecute(); ....call the service... instance.postExecute(); .... } I am not particularly interested in correctness of code as in correctness of thinking and approach. Actually I have to do this in PHP, witch I see as a kind of Pop music of programming which I have to "sing" for commercial reasons, even though I play POP I really want to sing by the book, so putting aside my more or less inspired analogy I really want to know your opinion on this matter for it's practical necessity and technical approach. Thanks

  • How long will an ASP.NET MVC application run

    - by Christoph
    I wonder how long will an ASP.NET (MVC) application run, when no new requests come in? Lets say I'm using an IOC Container ans have a Singleton Object serving to the clients. As far as I know it will serve different page requests. But how long will it live when no new request come in? Is there any timeout (maybe configured through IIS) that says when my app will shut down?

  • Windows Service WebBrowser DocumentCompleted Bug

    - by Sam Youtsey
    I've been building a Windows Service to create a WebBrowser object to navigate, login, and download a site's HTML. However, I recently discovered this bug which prevents the DocumentCompleted event from firing if the WebBrowser is not visible: http://support.microsoft.com/kb/259935 I've got to assume this is because the Windows Service doesn't allow for a GUI and therefore this bug is tripped. What is the best workaround for this? Thanks for your help.

  • How to sort an array of structs in ColdFusion

    - by Kip
    I have an array of structs in ColdFusion. I'd like to sort this array based on one of the attributes in the structs. How can I achieve this? I've found the StructSort function, but it takes a structure and I have an array. If this is not possible purely in ColdFusion, is it possible in Java somehow (maybe using Arrays.sort(Object[], Comparator))?

  • How to make a class serializable without Serializable attibute in .net

    - by Ashwani K
    Hello All: I have one debugger visualizer for seeing list of class object in the form of data table. But the limitation for the code is that the class should be serializable i.e. should be marked as [Serializable] and if the class is not marked Serializable then the debugger crashes. So, can anybody tell me how to make a class Serializable at run time if the class is not marked Serializable. Thanks Ashwani

  • ProgressDialog does not disappear after executing dismiss, hide or cancel?

    - by Martin
    Hello, I have an Overlay extension which has 2 dialogs as private attributes - one Dialog and one ProgressDialog. After clicking on the Overlay in the MapView, the Dialog object appears. When the user clicks a button in the Dialog it disappears and the ProgressDialog is shown. Simultaneously a background task is started by notifying a running Service. When the task is done, a method (buildingLoaded) in the Overlay object is called to switch the View and to dismiss the ProgressDialog. The View is being switched, the code is being run (I checked with the debugger) but the ProgressDialog is not dismissed. I also tried hide() and cancel() methods, but nothing works. Can somebody help me? Android version is 2.2 Here is the code: public class LODOverlay extends Overlay implements OnClickListener { private Dialog overlayDialog; private ProgressDialog progressDialog; .............. @Override public void onClick(View view) { ....... final Context ctx = view.getContext(); this.progressDialog = new ProgressDialog(ctx); ListView lv = new ListView(ctx); ArrayAdapter<String> adapter = new ArrayAdapter<String>(ctx, R.layout.layerlist, names); lv.setAdapter(adapter); final LODOverlay obj = this; lv.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> parent, View view, int position, long id) { String name = ((TextView) view).getText().toString(); Intent getFloorIntent = new Intent(Map.RENDERER); getFloorIntent.putExtra("type", "onGetBuildingLayer"); getFloorIntent.putExtra("id", name); view.getContext().sendBroadcast(getFloorIntent); overlayDialog.dismiss(); obj.waitingForLayer = name; progressDialog.show(ctx, "Loading...", "Wait!!!"); } }); ....... } public void buildingLoaded(String id) { if (null != this.progressDialog) { if (id.equals(this.waitingForLayer)) { this.progressDialog.hide(); this.progressDialog.dismiss(); ............ Map.flipper.showNext(); // changes the view } } } }
