  • Retruning reference to object not changing the address in c++

    - by ashish-sangwan
    I am trying to understand function returning reference. For that i have written a simple program :- include using namespace std; class test { int i; friend test& func(); public: test(int j){i=j;} void show(){cout< }; test& func() { test temp(10); return temp; //// Address of temp=0xbfcb2874 } int main() { test obj1(50); // Address of obj1=0xbfcb28a0 func()=obj1; <= Problem:The address of obj1 is not changing obj1.show(); // // Address of obj1=0xbfcb28a0 return 0; } I run the program using gdb and observed that the address of obj1 still remains same but i expect it to get changed to 0xbfcb2874. I am not clear with the concept. Please help. Thanks in advance

  • Returning reference to object is not changing the address in c++

    I am trying to understand functions returning a reference. For that I have written a simple program: #include<iostream> using namespace std; class test { int i; friend test& func(); public: test(int j){i=j;} void show(){cout<<i<<endl;} }; test& func() { test temp(10); return temp; //// Address of temp=0xbfcb2874 } int main() { test obj1(50); // Address of obj1=0xbfcb28a0 func()=obj1; <= Problem:The address of obj1 is not changing obj1.show(); // // Address of obj1=0xbfcb28a0 return 0; } I ran the program using gdb and observed that the address of obj1 still remains same, but I expect it to get changed to 0xbfcb2874.

  • Problem in DataBinding an Enum using dictionary approach to a combobox in WPF.

    - by Ashish Ashu
    I have a Dictionary which is binded to a combobox. I have used dictionary to provide spaces in enum. public enum Option {Enter_Value, Select_Value}; Dictionary<Option,string> Options; <ComboBox x:Name="optionComboBox" SelectionChanged="optionComboBox_SelectionChanged" SelectedValuePath="Key" DisplayMemberPath="Value" SelectedItem="{Binding Path = SelectedOption}" ItemsSource="{Binding Path = Options}" /> This works fine. My queries: 1. I am not able to set the initial value to a combo box. In above XAML snippet the line SelectedItem="{Binding Path = SelectedOption}" is not working. I have declared SelectOption in my viewmodel. This is of type string and I have intialized this string value in my view model as below: SelectedOption = Options[Options.Enter_Value].ToString(); 2. The combobox is binded to datadictionary which have two options first is "Enter_value" and second is "Select_value" which is actually Option enum. Based on the Option enum value I want to perform different action. For example if option is equal to option.Enter_value then Combo box becomes editable and user can enter the numeric value in it. if option is equal to option.Select_value value then the value comes from the database and the combo box becomes read only and shows the fetched value from the database. Please Help!!

  • [c]how to take input for a character pionter without using fget?

    - by ashish yadav
    consider the code include int main() {char* a; scanf("%s",a);//&a and &a[0] give same results-crashes printf("%s",); return 0; } why does this code results in crashing?whereas this code using character array works fine? include int main() {char a[100]; scanf("%s",&a[0]);//works fine printf("%s",a); return 0; } the difference being character array and pointer?but i knew that pointer just points to the first element that is &a[0] should work fine but upper code crashes for all three that is a,&a and &a[0]? the main thing i would to gather is how can i take input of a character pointer if i insist on using scanf only? i apologize if i am not clear. thanks in advance:)

  • Accessing the calling object into ajax response... (not the ajax call)

    - by Nishchay Sharma
    I have an object of type Application (defined by me). Whenever an object of this type is created, it automatically loads a php file say "start.php" using jquery ajax and assign the response to a div say "Respo". Now what i want is to access the Application object from that Respo div. Unfortunately, i have no clue how to do this... in my ajax call: function Application(options) { ....... var appObj=this; $.ajax({ url:appObj.location, //Already defined success:function(data) { $("#respo").html(data); } }); } Now in my Respo division i want to access that Application object... I tried: alert(this) but it resulted in an object of DOMWindow... i tried editing success function as: function Application(options) { ....... var appObj=this; $.ajax({ url:appObj.location, //Already defined success:function(data) { $("#respo").html("<script type='text/javascript'>var Self="+appObj+"</script>"); $("#respo").html(data); } }); } But i ended nowhere. :( Although if i assign "var Self='nishchay';" then alerting Self from start.php gives nishchay but i am not able to assign the calling object of Application type to the Self variable. It is the only way I cud think of. :\ Please help me... actually my object has some editing functions to control itself - its look and feel and some other options. I want the code loaded by object to control the object itself. Please help me.. Thanks in advance. Nishchay

  • How to Validate an XML Node against an XSD in C++?

    - by Ashish
    Hi Please note that I'm asking for validation against a particular node and not the whole file. For examples <somexmldoc> <someNode> <UserDefinedNode> </> <UserDefinedNode> </> </someNode> </somexmldoc> For this XML doc, I have an wholeDoc.XSD which could be used to validate the whole document except "UserDefinedNode" (This node is specified with "any" tag in xsd, which allows a user to define anything under that node). Is it possible to have a separate userdefined.XSD file to validate "UserDefinedNode"? Is it possible to use MSXML for C++ (IXMLDomDocument) to validate this? Thanks!

  • Vertically align UILabel

    - by Ashish Agarwal
    I am trying to vertically align the text in the UILabel view of my app. The problem is that I want the text to be vertically aligned to the top and the size of the label to be 280 x 150. I am only able to achieve one of these 2 things. If I remove the line [myLabel sizeToFit]; then the alignment of the text is alright but the size is messed up. But if I add the above line, then the alignment is messed up but the size is alright. How do I fix this problem. I've added the code below - CGRect labelFrame = CGRectMake(22, 50, 280, 150); UILabel *myLabel = [[UILabel alloc] initWithFrame:labelFrame]; [myLabel setText:finalRecipe]; [myLabel setBackgroundColor: [UIColor lightGrayColor]]; [myLabel setNumberOfLines:0]; [myLabel sizeToFit]; [self.view addSubview:myLabel];

  • why does the array doesn't get initialized by global variable , even though it should not?

    - by ashish yadav
    why does the array a does not get initialized by global variable 'size'. include int size=5; int main() { int a[size]={1,2,3,4,5}; printf("%d",a[0]); return 0; } the compilation error is shown as "variable-sized object may not be initialized". according to me the array should get initialized by 'size'. i apologize if i am not clear but i feel i have expressed myself well enough. thank you!!!!!!!!!!!

  • Focus problem with multiple EditText's.

    - by Ashish
    I have an activity with two edittext controls. I am calling the requestFocus on the second edittext field since by default the focus goes to the first edittext control. The focus appears to be in the second edittext field (the second one gets the highlighted border), but if we try to enter any characters using the hardware keyboard the text appears in the first edittext control. Any ideas why it would be happening?

    Why it is not allowed to overload "=" using friend function? I have written a small program but it is giving error. class comp { int real; int imaginary; public: comp(){real=0; imaginary=0;} void show(){cout << "Real="<<real<<" Imaginary="<<imaginary<<endl;} void set(int i,int j){real=i;imaginary=j;} friend comp operator=(comp &op1,const comp &op2); }; comp operator=(comp &op1,const comp &op2) { op1.imaginary=op2.imaginary; op1.real=op2.real; return op1; } int main() { comp a,b; a.set(10,20); b=a; b.show(); return 0; } The compilation gives the following error :- [root@dogmatix stackoverflow]# g++ prog4.cpp prog4.cpp:11: error: ‘comp operator=(comp&, const comp&)’ must be a nonstatic member function prog4.cpp:14: error: ‘comp operator=(comp&, const comp&)’ must be a nonstatic member function prog4.cpp: In function ‘int main()’: prog4.cpp:25: error: ambiguous overload for ‘operator=’ in ‘b = a’ prog4.cpp:4: note: candidates are: comp& comp::operator=(const comp&) prog4.cpp:14: note: comp operator=(comp&, const comp&)
