C++ :: Calling Webservice Using GSoap - Error 400
Mar 18, 2013
I'm trying to call a webservice using gSoap with the following code:
Code:
#include "SoapH.h"
#include "BasicHttpBinding_USCOREIAuthentication.nsmap"
int _tmain(int argc, _TCHAR* argv[]) {
struct soap soap;
soap_init(&soap);
[Code] ....
I get the following error:
Error 400 fault: SOAP-ENV:Server [no subcode]
"HTTP Error"
Detail: HTTP/1.1 400 Bad Request
Press any key to continue . . .
I get the same error trying to connect to different services.

I'm new to C/C++. I'm trying to make a program that's going to use the CBLAS libraries that I downloaded on BLAS. After fighting tooth and nail with VC 2005 (I downgraded on purpose because at one point I was desperate.) with regards to solving compilation errors and such and eventually it all compiled just fine.
The problem now is, I get the above mentioned error. It says: "Unhandled exception at 0x0040271c in Try.exe: 0xC0000005: Access violation reading location 0x4e18feb8."
Now there are a few .cpp files (I'm compiling as C code.) which contain the functions and there is one other one which contains my main method. Using the debugger, it goes through 3 files all in all.
The main file: Code: /* cblas_example2.c */
#include <stdio.h>
#include <stdlib.h>
#include "cblas.h"
#include "cblas_f77.h"
[Code] .....
I get the above-mentioned exception in the last line, or:
Code: cblas_dgemm( UNDEFINED, transa, transb, *m, *n, *k, *alpha, a, *lda, b, *ldb, *beta, c, *ldc );
The debugger tells me what the address in the exception is the address if *ldc.

#include <cstdio>
#include <cstdlib>
int main () {
int i;
printf ("Checking if processor is available...");
if (system(NULL)) puts ("Ok");
[Code] ....
is the syntax correct for system? i am getting error " error: perl was not declared in this scope"

In C you can just load and call the address of a function without defining its arguments like this:
Code: int (__stdcall *pMessageBox)();
int main() {
HMODULE h=0;
h = LoadLibrary("user32.dll");
pMessageBox = GetProcAddress(h, "MessageBoxA");
// MessageBoxA
pMessageBox(0, "MessageBoxA has been called!", "MessageBox Example", MB_OK);
return 0;
}
In C++ the same code gives "too many arguments for call" error unless you define the function first with its parameters.
Is there a way to do it the same way in C++?

I have two projects (Projects A and B). Project A is a dll project, defining a function called "regex".
Project B dynamically loads this DLL, and calls Project A's "regex" function via LoadLibrary/GetProcAddress.
Regex takes a pointer to an std::vector (std::vector<std::cmatch>).
When debugging ProjectB, I can see that, within the code from ProjectA (in the "regex" call), a loop that loops through the elements of the vector outputs all the elements in the vector to console as expected. But the loop in ProjectB ( which executes after ProjectA), which also loops through the vector, and, is supposed to output the elements of the vector, outputs empty strings, not, as I would expect, the same strings (which contain results), as in the loop in Project A.
How is this happening. Does this have anything to do with it being a DLL, and, maybe, somehow values/memory addresses (or something similar) of the vector/its elements being destructed across the Projects/Dlls?
Output and Code See Below:
Output Loop in A:
Un
Un
Output Loop in B: (empty) (i.e. none)
Project A DLL Header (interface.h):
#include "stdafx.h"
#include <vector>
#include <regex>
extern "C" {__declspec(dllexport) int __cdecl regex(std::string target,std::string rgx, std::vector<std::cmatch*>* matches);}

I 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.

I am using a dll written in FORTRAN to do some calculations and here is how I have set up the program. I have created following files:
C++ source files:
main.cpp
File1.cpp
Header Files:
Datamain.h
DataFile1.h
[Code]....
Here are my questions:
1) I actually want to call Sub2dll from the main program. But the above program does not build and it gives me the following error: In function 'int main()': Sub2dll was not declared in this scope.
When I build this program with the call to Sub2dll in main commented out and instead put that call in File1::Setup function things build well and runs giving the answer expected. How can I make the call to Sub2dll from main.
2) I am including "Datamain.h" in main. However when I build it with out the declaration int Datamain::Index; in main, it gives me the following error: undefined reference to Datamain::Index When I add that declaration to main the error disappears.
I am usiing Code::blocks with MinGW compiler. I have not put the argument list for the subroutine calls since there were not errors in that part.

I have this sample code, that calls a function in a DLL. The function Callback is provided to the DLL as an argument, in order for the DLL to notify my program of relevant changes.
sample:
#include <iostream>
#include <conio.h>
#include <windows.h>
#include <winbase.h>
#include "TcAdsDef.h"
#include "TcAdsApi.h"
using namespace std;
void _stdcall Callback(AmsAddr*, AdsNotificationHeader*, unsigned long);
[Code] ....
I would like to change this code, so that there is a Main class that opens the connection and there are several separate classes (as below) that register themselves for a specific variable and get notifications if that value is changed. The reason for this is that I want to get several notifications for several independent events and I don't want them to mix. I figured this should look something like this:
class.h
#ifndef INACLASS_H
#define INACLASS_H
#include "Main.h"
class InAClass {
public:
InAClass(Main* mainClass, std::string iolocation);
[Code] ....
Unfortunately this gives me an error:
error: cannot convert 'InAClass::Callback' from type 'void (InAClass::)(AmsAddr*, AdsNotificationHeader*, long unsigned int)' to type 'PAdsNotificationFuncEx {aka void (__attribute__((__stdcall__)) *)(AmsAddr*, AdsNotificationHeader*, long unsigned int)}'
At first I thought this was because I don't have the namespace "using namespace std;" on top, but then I should be able to find something that specifically needs to come from the std namespace and is not marked as such. I don't want to rule the option out, but so far I could not find anything like that.
An alternative explanation might be that the Callback function needs to be global, but if I make it global, how can I distinguish between several Callback functions?

I created a simple program to understand it
class TestClass {
private int x = 10;
TestClass a = new TestClass();
[Code].....
I know this is recursion but how do the compiler do this? How can it call itself when it hasnt even completed initializing every object it has? Why do VS allow this?

So I am wondering how I would go about calling a function for all instances of an object. I tried googling it, but all I saw was solutions like making an array of pointers to the objects. What if I don't know how many objects there will be? Isn't there an easier way?

How do I call these functions from Mechanical.h???
Mechanical.h
#ifndef MECHANICAL_H_
#define MECHANICAL_H_
class statics { public:
template<class T> struct Inertia_types {
T Rec(T _x, T _y);
T Tri(T _x, T _y);
[Code] ...
I am trying to create templated functions which I can apply all data types to except for strings and other types such as wchar. Am I also writing these correctly? This is my first attempt ever doing this.

Just a few moments ago i was just doing foolish things in c++ and discovered something new. Though some of you might have known this, for those who dont know, take a look at the follwing 2 small programs,
#include <iostream.h>
#include <conio.h>
void main();
void loop()
[Code]....
so here is my problem. i think u wud have figured out what m trying to do above. am actually calling the main() of the class and from there, i want to call the usual main... the problem is, during A.main()'s run, if i refer to main(); , that call represents itself, that it, it is like it calls itself. How on earth can i call the outside main?

int OpenCD();
int main() {
char ArtistName[25];

I am trying to use ofstream to write in a txt file in a function called recurrently. for a simplified example:
void func_write(double x) {
ofstream myfile;
myfile << "the result = " << x << endl;
} int main() {
ofstream myfile;
[Code] .....
To this stage, it does not work, because the myfile in func_write cannot write in the txt file opened in main function. I don't want to open, append and close the txt file each time the function is called, that will take more time to execute all (imagine with 500 calls).

I want to update a label from Form2. When I click on the button on Form 2, the textbox on Form2 should update the label on Form1 and take me to a certain website. What ever URL is typed into the textbox on Form2 is what website URL the label on Form1 will take me to. The label on Form1 can say something such as You can check out my website here!!! and when they click on the saying it takes me to their website.

I created 3 Rectangle pointers. And later in the program, I would like to modify these existing Rectangles by calling constructors with parameters. Is this possible? I have a sense that it involves creating overload operators, but I am not sure how to do it, or if that's the correct path.
#include <iostream>
#include <string>
using namespace std;
// Base class
class Shape {
protected:
int width;
int height;

class abc {
public:
int i;
abc * foooo;
};
How do you call * foooo? Say I create:
abc a;
* foooo would have some values for int i.
To get int i of *foooo, I tried a.foooo.i, which doesn't work. How do you call it?

and the TheoraVideoClip.h file is in /root_project/include/theoraplayer/.
Inside of TheoraVideoClip.h there is this:
Code: TheoraVideoFrame* getNextFrame();
And when I try to compile using g++ -o app main.cpp -lGL -lglut -lGLU -ltheora -ltheoradec -ltheoraenc I'm gettin this error:

I would like to call a script from a makfile to glean some information about the OS. What I more or less need is the OS name and version (CentOS-5.9, OPENSUSE-12.2, Cygwin, etc). I think I can get the rest of what I need from uname. The OS name and version doesn't seem to reside in any consistent place over the various Linux flavors. I also need to get the version of the gnu c compiler, since I think that may also require a bit more involved scripting than I would like to try out of make.
The main question is weather I can call a script out of make and have it return a value for a variable.
Something like,
OS := $(shell ./script_name)

Every time we pass an object to a function, and when the function ends and the object is not necessary anymore the destructor is called. if it's passing by value then a copy of the object is passed. if the object has a pointer inside of it so we implement the copy constructor to create a new pointed-variable so the original pointer will not get deleted.
so far so good. But what about passing an object to a non-member function by reference?
The language says that as soon as the function ends - the object will be deleted , because we passed by ref. that means that after the function ends - the object is not usable anymore! =What does that say? that in c++ you can't pass object by ref. because it will get deleted and un-uasable??
Varifying it with a compiler shows that the object is NOT deleted after the function ends.
