  • calling a method on the parent page from a user control

    - by Kyle
    I am using a user control that I created (just a .cs file not an .ascx file), that does some magic and depending on a value generated by the control, I need it to do something on the parent page that is 'hosting' the control. It needs to call a method under certain circumstances (method is on the parent control). the control is placed on the parent page like so: <customtag:MyControl ID="something" runat="server" /> I'm dynamically creating buttons etc on the control itself but when a button is clicked, let's say for example that there's a text box on the control and if the value of the textbox is "bob" it needs to call a method on the page that's housing the control...how can I accomplish this?

  • Method params match signature, but still getting error

    - by Jason
    I am in the midst of converting a VB library to C#. One of my methods has the following signature in VB: Private Shared Sub FillOrder(ByVal row As DataRowView, ByRef o As Order) In C# I converted it to: private static void FillOrder(DataRowView row, ref Order o) From my constructor inside my Order class, I am calling the FillOrder() method like so: DataView dv = //[get the data] if (dv.Count > 0) { FillOrder(dv[0], this); } In VB, this works: Dim dv As DataView = '[get data]' If dv.Count > 0 Then FillOrder(dv.Item(0), Me) End If However, in VS10 in the C# file I am getting a red squiggle under this call with the following error: The best overloaded method match for [the method] has some invalid arguments This was working code in VB. What am I doing wrong?

  • Utility method - Pass a File or String?

    - by James P.
    Here's an example of a utility method: public static Long getFileSize(String fileString) { File file = new File(fileString); if (file == null || !file.isFile()) return null; return file.length(); } Is it a good practise to pass a String rather than a File to a method like this? In general what reasoning should be applied when making utility methods of this style?

  • Find who's calling the method

    - by Marcos Placona
    Hi, I'd like to somehow find out which CFC is calling my method. I have a logging CFC which is called by many different CFC's. On this logging CFC there's a need to store which CFC called for the log. Whilst I could simply pass the CFC name as an argument to my log.cfc, I find this to be a repetitive task, that might not be necessary, if I somehow could find out "who's" calling the method on log.cfc Is there any programmatic way of achieving this? Thanks in advance

  • How to explain method calls?

    - by forki23
    Hi, let's consider a small method: int MyFunction(string foo, int bar) { ... } and some calls: MyFunction("",0) int x = MyFunction(foo1,bar1) How would you explain this to a non-technical persons? Has anybody a nice metaphor? I tried to explain method calling (or function application) several times, but I failed. Seems I can't find the right words here. Regards, forki

  • Detecting end of method chain in PHP?

    - by fabrik
    Hello! I cannot find a simple example about my question above: how can i detect the end of a method chain? I'm just looked Zend_Db_Select for example but this one is too complex for this simple question i think. Is it possible to catch the 'end' of a method chain in PHP? thanks, fabrik

  • Overload method (specifically drawRect:) without subclassing.

    - by SooDesuNe
    I'm using a container UIView to house a UIImageView and do some custom drawing. At this point I'd like to do some drawing on top of my subview. So overriding drawRect: in my container UIView will only draw below the subviews. Is there a way to overload drawRect: in my subview without subclassing it? I think method swizzling may be the answer, but I'm hoping not. (NOTE: yes, it would have been smarter to have the UIView be the subview of the UIImageView, but unfortunately I'm committed to my mistake now.)

  • ATI graphics card overriding onboard Intel graphics

    - by Patrick
    I have an ATI graphics card with an AGP connection and a DVI port, and an Intel graphics processor on the motherboard with a VGA port. I have two monitors. When the graphics card is unplugged, I get this from lspci: 00:00.0 Host bridge: Intel Corporation 82G33/G31/P35/P31 Express DRAM Controller (rev 10) 00:02.0 VGA compatible controller: Intel Corporation 82G33/G31 Express Integrated Graphics Controller (rev 10) When it is attached, I get this: 00:00.0 Host bridge: Intel Corporation 82G33/G31/P35/P31 Express DRAM Controller (rev 10) 01:00.0 VGA compatible controller: ATI Technologies Inc RV380 [Radeon X600 (PCIE)] 01:00.1 Display controller: ATI Technologies Inc RV380 [Radeon X600] Note the absence of 00:02.0 - this is apparently causing the VGA monitor to say "No Signal" and the only the DVI display to show up in the list. I checked for problems in xorg.conf... there isn't one. I have no idea how to build one.

  • Customizing / overriding ComboBox (2 replies)

    Hi, I would override a Windows.Forms.Combobox to have a MyObjectCollection instead of a ObjectCollection as Items property. I've try writing this code, but it seems that items are stored somewhere else (not in Items property). I can add items to collection but when I try to select an item from the combobox (at runtime) an exception tells me that there is no such element in Items (litterally it tel...

  • nVidia Settings: Overriding anti-aliasing causes delay

    - by Kalle Elmér
    I'm using Google Sketchup on ubuntu 12.04 with Wine 1.4. It works flawlessly out of the box, but anti-aliasing is causing some problems. I can override anti-aliasing settings using the nVidia X Server Settings utility, which results in a great-looking image. However, the view doesn't seem to update properly. It's a bit hard to explain, but if I do something (e.g. zooming) the changes won't appear in the view until I take another action. in other words, there seems to be a delay of one "action". Take this example. The mouse wheel is moved one notch to zoom in one step. Nothing happens. An object is selected by clicking. The new zoom is rendered but the selection box doesn't appear. An empty area is clicked. The selection box appears. Is there something that I can do to solve the problem? Could I force the GPU to redraw that view with a certain interval, or is there some other solution? I really like anti-aliasing, but it's hard to use when drawing stuff.

  • How to set MANPATH without overriding defaults?

    - by balki
    I have added extra directories to $PATH by exporting PATH=/my/dirs:$PATH But I am not sure if I should do the same to MANPATH. Because default MANPATH is empty yet man command works. I found a command called manpath and its manual says If $MANPATH is set, manpath will simply display its contents and issue a warning.. Does this mean setting MANPATH is not the right way to add directories for man command to search for manual pages?

  • QML: Overriding a signal handler from other element

    - by user3490458
    Is it possible to override an elements action (eg onTriggered() of a Timer) from within the onClick() of a button? Something like so- Button { id: centerBtn objectName: "button" onClicked: { delaytimer.running = true; delayTimer.onTriggered {}; // override here } Timer { id: delaytimer interval: 1000 running: false repeat: false onTriggered: //something implemented here } }

  • Using "prevent execution of method" flags

    - by tpaksu
    First of all I want to point out my concern with some pseudocode (I think you'll understand better) Assume you have a global debug flag, or class variable named "debug", class a : var debug = FALSE and you use it to enable debug methods. There are two types of usage it as I know: first in a method : method a : if debug then call method b; method b : second in the method itself: method a : call method b; method b : if not debug exit And I want to know, is there any File IO or stack pointer wise difference between these two approaches. Which usage is better, safer and why?

  • Overriding a function in an instance [on hold]

    - by MustSeeMelons
    Is it possible to override a function by instance? For example, A and B are both instances of MyClass. I have a function Action(), and I want to specify its implementation for each instance. To be more specific - the class is a Button, and the function is Clicked(). I don't want to derive a class 5 times to create 5 different button actions. Was thinking of something like it's handled in Java Swing: create a button, add code for the button press and use the button.

  • JUnit Easymock Unexpected method call

    - by Lancelot
    Hi, I'm trying to setup a test in JUnit w/ EasyMock and I'm running into a small issue that I can't seem to wrap my head around. I was hoping someone here could help. Here is a simplified version of the method I'm trying to test: public void myMethod() { //Some code executing here Obj myObj = this.service.getObj(param); if (myObj.getExtId() != null) { OtherObj otherObj = new OtherObj(); otherObj.setId(myObj.getExtId()); this.dao.insert(otherObj); } //Some code executing there } Ok so using EasyMock I've mocked the service.getObj(myObj) call and that works fine. My problem comes when JUnit hits the dao.insert(otherObj) call. EasyMock throws a "Unexpected Method Call" on it. I wouldn't mind mocking that dao in my test and using expectLastCall().once(); on it, but that assumes that I have a handle on the "otherObj" that's passed as a parameter at insert time... Which of course I don't since it's conditionally created within the context of the method being tested. Anyone has ever had to deal with that and somehow solved it? Thanks.

  • Abstract Methods in "Product" - Factory Method C#

    - by Regina Foo
    I have a simple class library (COM+ service) written in C# to consume 5 web services: Add, Minus, Divide, Multiply and Compare. I've created the abstract product and abstract factory classes. The abstract product named WS's code: public abstract class WS { public abstract double Calculate(double a, double b); public abstract string Compare(double a, double b); } As you see, when one of the subclasses inherits WS, both methods must be overridden which might not be useful in some subclasses. E.g. Compare doesn't need Calculate() method. To instantiate a new CompareWS object, the client class will call the CreateWS() method which returns a WS object type. public class CompareWSFactory : WSFactory { public override WS CreateWS() { return new CompareWS(); } } But if Compare() is not defined as abstract in WS, the Compare() method cannot be invoked. This is only an example with two methods, but what if there are more methods? Is it stupid to define all the methods as abstract in the WS class? My question is: I want to define abstract methods that are common to all subclasses of WS whereas when the factory creates a WS object type, all the methods of the subclasses can be invoked (overridden methods of WS and also the methods in subclasses). How should I do this?

  • Rails does not display error messages on a form in a custom method

    - by slythic
    Hi all, I've created a custom method called checkout in my app. I create an order (which is done my adding products to my "cart"), assign it to my client, and then I head to my checkout screen where I confirm the items and enter their customer order number and complete the order (submit). Everything works great except that it doesn't display error messages. I'm able to display a flash error notice (seen in complete_order method) when things go wrong but it doesn't specify the details like a normal form would. The error messages should appear if the customer order number is not unique for that client. Below is the custom method (checkout) related code. Order Model: validates_uniqueness_of :customer_order_number, :scope => :client_id Orders_controller: def checkout @order = current_order end def complete_order @order = current_order respond_to do |format| if @order.update_attributes(params[:order]) @order.complete #sets submitted datetime and state to 'complete' flash[:notice] = 'Thank you! Your order is being processed.' format.html { redirect_to( products_path ) } format.xml { head :ok } else flash[:error] = 'Please review your items' #added to confirm an error is present format.html { redirect_to( checkout_path ) } format.xml { render :xml => @order.errors, :status => :unprocessable_entity } end end end And the form in the checkout view: <% form_for @order, :url => { :controller => "orders", :action => "complete_order" } do |f| %> <%= f.error_messages %> <%= f.text_field :customer_order_number, :label => "Purchase Order Number" %> <p> <%= f.submit 'Complete Order', :confirm => 'Are you sure?' %> <small> or <%= link_to 'cancel', current_cart_path %></small> </p> <% end %> Any idea how I can display the specific error messages? Thank you in advance! -Tony

  • Calling a method at a specific interval rate in C++

    - by Aetius
    This is really annoying me as I have done it before, about a year ago and I cannot for the life of me remember what library it was. Basically, the problem is that I want to be able to call a method a certain number of times or for a certain period of time at a specified interval. One example would be I would like to call a method "x" starting from now, 10 times, once every 0.5 seconds. Alternatively, call method "x" starting from now, 10 times, until 5 seconds have passed. Now I thought I used a boost library for this functionality but I can't seem to find it now and feeling a bit annoyed. Unfortunately I can't look at the code again as I'm not in possession of it any more. Alternatively, I could have dreamt this all up and it could have been proprietary code. Assuming there is nothing out there that does what I would like, what is currently the best way of producing this behaviour? It would need to be high-resolution, up to a millisecond. It doesn't matter if it blocks the thread that it is executed from or not. Thanks!

  • Calling overridden method from within overriding method in OO PHP

    - by paddymcc
    Working in a symfony model, I want to override a function and call the overridden function from within the overriding one, along the lines of class MyClass extends BaseMyClass { function setMyProperty($p) { parent::setMyProperty($p); //do some other stuff } } This is resulting in a segmentation fault. I don't want to alter the parent class - it's been generated by symfony, and may feasibly be overwritten in the future if the model is rebuilt. This seems like something that should be straightforward, but I'm struggling to find the solution. Thanks for any advice

  • How can I call a method given only its name?

    - by mfolnovich
    I'm trying to have method void run( string method ) which would run method in that class. For example: class Foo { public: void run( string method ) { // this method calls method *method* from this class } void bar() { printf( "Function bar\n" ); } void foo2() { printf( "Function foo2\n" ); } } Foo foo; int main( void ) { foo.run( "bar" ); foo.run( "foo2" ); } this would print: Function bar Function foo2 Thanks! :)
