C++ :: Invalid Conversion Error - Ambiguous Typecast
May 4, 2013
The compiler keeps on telling me that invalid conversion from wxBitmap* to wxString on the line with the AddTool function, whiles I do not even try to do such an ambiguous typecast.
wxWidgets 2.9.4
MinGW
gdb
Code:
#include "mainwnd.h"
//namespaces
//other definitions and declarations
CMAINWND::CMAINWND(const wxString& szTitle):wxFrame(NULL,wxID_ANY,szTitle) {
wxImage::AddHandler(new wxBMPHandler);
Okay so inside my ArcherArmor.cpp, I'm trying to figure out why the map initializer list isn't working, but for some reason I keep getting "Error C2593: 'operator =' is ambiguous". Here is my code:
I also have a class which ArcherArmor is derived from, that has a struct called `Armor`, which I left out for simplicity. The main problem is that error! The only thing I can think of is that im initializing the map wrong.
After looking online for a string replace function in C and finding so many examples that go through the entire string twice. First round to find how number of occurances of substitute in string, using that to malloc for a new string to include additional space for replace, then going through the search string again to get all but what's to be substituted out. I feel it's kind of silly to go through the string twice. Therefore, I'm trying to implement my own string replace, that only searches through the string for what's to be substituted, once.
Here is the same code, but with execution + some syntax highlighting: Ideone.com | Online C Compiler & Debugging Tool..It works great, until it gets to grabbing whatever remains in the search string after the last found sub. The realloc throws a runtime error:
Aborted From my understanding, this is from me going outside of the bounds of the heap and using memory I haven't allocated, or using a free'd pointer. I'm not seeing where either of these are happening in my code, and was wondering what the best way to go about figuring out where the error exactly occurs.
The exercise consists on 3 procedures. We get the information from a .txt like these:
01/03/2011 A 02/03/2011 F 03/03/2011 C 04/03/2011 T (...)
Simulating a Videoclub database where the letters stand for the type of movie (A=Action, T=Terror, C=Comedy, ...) and the dates they were rented.
a) How many movies from one specific genre have been rented more than 'n' times? The genre and the value 'n' must be entered by the user.
b) How many movies and which genres belong to a certain date? The date must be entered by the user.
c) Print a list that shows the number of times a movie from each genre has been rented.
So far this is what I've got:
Code: #include <stdio.h> #include <stdlib.h> #include <string.h> #define MAX 100
typedef struct { int dia,mes, any; char genere;
[Code] ....
But right now, my main problem is that I can't even debug because i get an error in line 97 --> while (llista[i][j] != EOF) <-- saying "invalid operands to binary != (have 'lloguer' and 'int').
I've tried to cast (int) before "llista[i][j]" but it says that I'm already supposed to get an integer from that.
I am using visual studio 2012 on windows 7. but, when I have compiled my programs and run them on an older pc to test out its functions, I receive an error saying that the program is not a "valid win32 application." I have even tested this with a very simple hello world console application, but the problem still remains. Where is the error coming from? is the application corrupted during transport? (upload to internet) or are programs compiled on win 7 incompatible with win xp
So the thing is I have 2 forms, form 1 is displayed first, and form2 would be open when click the next button on form1.
So i was success in moving to the next form, and even getting back to the previous, and then next again, but on the second time I try to go back from form2 to form 1, this error show up.
The error:
Form that is already displayed modally cannot be displayed as a modal dialog box. Close the form before calling showDialog.

This code works on Windows, how can I get it to work on Linux?
i want to modify value of whole array by passing it to a function and make each value of array multiplied by 3 ,return the value to main and print it using pointer.
error : invalid Lvalue is the error
Code:
#include<stdio.h> main() { int i,arr[10]; for (i=0;i<=9;i++) { printf("Enter value of arr[%d] : ",i); scanf("%d",&arr[i]);
getting an invalid null pointer error message after a successful build. This program is supposed to ask for firstName, lastName, age and maJor and keep doing so until the age that is input is 0 and then the program closes. Here is what I have.
#include <iostream> #include <string> using namespace std;

[Code] .....
And in the /// part I also need to use the dot operator and the arrow operator to print on the screen info about the second and third Courses.
so i have this problem with my code ( not running)i want to read ( 2 double numbers x,y) and ( one integer z) then calculate reminder of x and y ( after they both converted to integer) and the formula : x^2 + y^2 + z^2and : x^z + y^z
here is what i came up with :
Code: // compute.c
#include<stdio.h> #include<math.h> int main(void) {
[Code]....
it also says in q : be sure to test the user input to make sure x,y,z are positive . any negative or zero should not be accepted and must print error msg ==> do i have to have an if statement here ? or the while loop is enough ?
Write your question here. Hello World not working they say 1>------ Build started: Project: HelloWorld1, Configuration: Debug Win32 ------ 1>LINK : fatal error LNK1123: failure during conversion to COFF: file invalid or corrupt ========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

I'm using GCC 4.8.1 and I want to implement a XML parser using TinyXML and port it to AngelScript
Now, it says: reference to 'Column' is ambiguous
I've declared a class called xml_parser and I've added everything of tinyxml as it's public member when I call Column(), and also Row(), it give's this error. what should I do?
I need to make a stub for some standard library function, but the compiler gets confused about which function I want to call in my code. I thought that putting the stubbed function together with its caller into an anonymous namespace will give higher precedence to the stub, but it didn't.
Result: main.cpp: In function ‘void {anonymous}::test()’: main.cpp:23:47: error: call of overloaded ‘sigaction(int, sigaction*, NULL)’ is ambiguous main.cpp:23:47: note: candidates are: main.cpp:8:5: note: int {anonymous}::sigaction(int, const sigaction*, sigaction*) In file included from main.cpp:4:0: /usr/include/signal.h:266:12: note: int sigaction(int, const sigaction*, sigaction*)
It possible to force the compiler to use my stubbed version of sigaction() and if yes, how to do that? I am not allowed to modify test() function.
I am working on my project of gesture recognition using c++ and open cv and i am also designing GUI simultaneously. I am using system namespace for GUI part and cv namespace for gestures.
After compiling i am getting error as Ambiguous symbol String is used.

#include "tensor.h" int main() { Tensor<2,-2> m = {{1,2},{1,3}}; Tensor<2> v = {1,5}; std::cout<<m*v<<"
[Code] ....
Why do I get an ambiguity and why is not the wanted operator*-overload (the last one in the tensor.h file) not even mentioned as one of the candidates? Is it clear what I want to do? And if so, what can I do to make the call unambiguous?
I get the following error in XCode whenever I try to access the member I created 'randomGen' in a separate class in a different header file. I have made sure to include the header file and have tried to access it through an object.
This is the code I enter when trying to access the method from randomiser.h in main.cpp. It is also an overloaded function with doubles and integers:
RandomG randomiser; randomiser.randomGen(); // 'Call to member function 'randomGen' is ambiguous'
This is the code inside randomiser.h:
#include <string> #include <iostream> using std::string; using std::cout; using std::endl; class RandomG {
[Code] ....
This is the error inside xcode: [URL] ....
I have tried seperating the code for the functions in another class (main.cpp) and then running and it seems to works, so I'm not sure why I can't put everything in the .h file and then access it?
I would like it in a seperate file so it doesn't clutter my main. I am writing a game with SDL so that might be confusing and I would like the window to have a random title and other random properties, so it would be easier to use a function.
