C++ :: Syntax Error In Function Call - Type Mismatch In Parameter In Function Sort

Visual C++ :: Error C3867 Function Call Missing Argument List For Calling Thread Function
Mar 19, 2013I searched the web for error: C3867... and the discussions where murky or obscure.
My code excerpt is:
#pragma once
#include <windows.h>
#include <stdlib.h>
#include <process.h>
void PutUpfrmIO(void *);
namespace WordParsor {
[Code] .....
I get the generic message:
error C3867: 'WordParsor::Form1::PutUpfrmIO': function call missing argument list; use '&WordParsor::Form1::PutUpfrmIO' to create a pointer to memberc:userskingc++wordparsorwordparsorForm1.h... and the suggestion fix generate another error.
One person suggested the gcroot<> object wrapper... but I do not know how to modify/declair the function or its argument type.
C++ :: Call Stack Should Include All Active Sub-routines?
Feb 4, 2015I have a general question on Call Stack of Embedded uCs.
The Call Stack should include all the Active Sub-routines.
For example, in the following sequence:
Func 1 Starts -- Call Func2 --> Func 2 Starts -- Call Func3 --> Func 3 Starts --> YOU ARE HERE
The Stack should include the Return Addresses of Func 2's Body and Func 1's Body, Right?
At any certain moment (e.g. when the uC experiencing a SW Bug), Is it possible to have the uC to get all the Active Sub-Routines from the Stack and print them (e.g. for knowing it at the moment of Bug)?
It'd debug failures, when I don't work with a Debugger.
I know that Debuggers do that - i.e. show you the Call Stack at each moment - So I am wondering if I can get the uC to to it for me every time a bug occurs.
C++ :: Call Of Non Function
Jan 9, 2015I have decalred a password function which accepts an array as parameter but while compiling, it's showing an error wherever I have called it.
void password(char a[100])
{
if(::q==1) { cout<<"
Enter the master password : "; goto ENTER; }
[Code]....
Wherever I have called this function it's showing an error: "Call of nonfunction." One of the examples of the errors is below:
::q=1;
password(master_password);
//Both 'q' and 'master_password' being global variables, and master_password being array of size 25.
C/C++ :: Can't Call A Function
Jan 12, 2015I wrote a program which detects a pattern in an array then returns a valve (x) for each time it does. now i tried to call function patt in main so that i can print x but it doesn't let me do it.
#include <stdio.h>
int patt(const int SIZE, char str[], int i, int c);
int main(void) {
const int SIZE=21;
char str[SIZE]={'1', '0', '1', '1', '0', '0', '1', '0', '1', '0', '1', '0', '0', '0', '1', '0', '1', '1', '0', '1'};
int i, c=0;

C :: Possible To Call A Function During Execution?
Feb 16, 2013I want to write a function and be able to call it during execution (say during a while(1) loop). Is this possible without having to parse an input string to extract the function and parameters I need or is that the only way?

C++ :: No Matching Function To Call?
Sep 6, 2013The random method in here should return a random value inside given array.
The program constantly crashes when I send the array object as full.
It will only allow for you to choose the first 4 objects in the array, if you choose object number 8, for example, the program crashes.
So Im trying to send the pointer to the array instead. But now the compiler claims not to know of any such function.
static string getRandom(string* avalible[]){
cout << "Get random";
cout << "index: " << (*avalible)->length() << endl;
int index = random((*avalible)->length()-1);
cout << "returned" + index;
[Code] .....
I can remove the "10" from the string first[10] but it doesn't make a difference.What is wrong with this?

C++ :: Function Call Is Skipping
Sep 13, 2013When I call the member function in the main function, two functions are working fine but the third one(print()) is not. The program stops after executing the read_ages function and nothing printed on the screen. This is really strange and I could not find any problem after spending hours and had to post it here.It is a very simple program but I cant find the bug. It is a multiple file program and I am using MinGW as a compiler.
//File 1
#include<vector>
#include<string>
class Name_pairs {
private:
std::vector<std::string>names;
std::vector<double> ages;
[Code] ...
//I haven't made the sort function yet since I am stuck with the print(). Seems //like the compiler is skipping the print() function.

C :: How To Call Function With Correct Arguments
Sep 13, 2013I'm not a programmer, at least, not a good one. I'm a researcher and I need to implement this function and test it and use it for my research. I tested some clustering methods in JAVA and Matlab and also I want to test it on C. I don't know too much about programming, especially about C, I know nothing. I tried to implement some basic methods but I failed.
It's all about K-Means Algorithm. I'm working on a disease and I'm trying to find ways to early diagnosis. Anyway, these are details. The thing is, I found a 'free to use' function but I don't know how can I use it. I tried to learn something from Net, I downloaded a compiler, I paste the code and I get many errors... And I heard that I have to do some "calling function" stuff but I don't know how to..
The code is in the link below: URL....It's not imperative that using this function, it can be another one but it had to written in C.
C :: System Call For A Pause Function
Jan 20, 2014 I know there has to be a system call for a pause function. I simply want the program to pause for a few seconds before executing the next line of code. I do NOT want the user to enter a keypress, just pause the output or code execution for a few seconds.
system (pause); waits for keypress right? I just want it to wait 3 seconds before proceeding. I know it should take an argument for milliseconds right? Also, this is for a homework assignment I have already completed, just doll'in it up a bit for extra credit...maybe...

C++ :: Request For Member When Call Function
Oct 22, 2013I'm writing a small c++ program which will be able to do a few things with a matrix. I have a class called Matrix and a member function in it called getSor() which returns an integer value about the number of lines in the matrix. When I call this getSor() function the program says: error: request for member ‘getSor’ in ‘matrix’, which is of non-class type ‘Matrix*’
- 'matrix' is an existing Matrix object here
- I called the function like this: "cout << matrix.getSor() << endl;"
C++ :: Call Function With Arguments From Java
Sep 19, 2013I am working on a project in a group at a university. We are creating a GUI in Java where the user can enter parameters. Then we want to be able to pass these parameters to a function inside our C/C++ program, that does the rest. How do I do this? So far I have managed to call a simple helloworld-function by using JNI, dll and a javah tool that create a header file from a java file. I define the helloworld-function in C and call it from Java.
Java file:
package helloworld;
public class HelloWorld {
private native void print();
public static void main(String[] args) {
[Code] ....
My problem is that I do not know how to call the helloworld-function with parameters. I guess that this is a special case when using JNI and a . dll. How do I pass simple char- and int-arguments from the Java class to the helloworld-C-function?

C++ :: No Matching Function For Call To Class
Nov 4, 2014I'm having this pain in the ass error (No matching function for call to Data::Data() ) on this block of code:
Etapa::Etapa(string nm, float dist, string loc, Data dt) {
nome = nm;
distancia = dist;
local = loc;
data = dt;
}
[Code].....
I guess this is happening because I'm trying to give Etapa an argument of Data type and I can't do it or put it in a variable since it has 3 parameteres (mes, dia, ano).
