I have an error from scanf.
error C4996: 'scanf': This function or variable may be unsafe. Consider using scanf_s instead.
int a = 0, b = 0;
char op = 0;
int result = 0;
scanf("%d %c %d", &a, &op, &b);Error disappeared after change it to scanf_s.
What is the difference between scanf and scanf_s?
As you can see not all the words will be in both
I want to place the contents of these files into arrays where I will compare the words. I also want to output wether the word has been found, the index location in the array
for example: "owl", found, location 1
"dog", Not found
void SingleParameter(char letters);
void ReadFile(ifstream& infile);
int main()
{
ifstream infile("line.txt");
ReadFile(infile);
ifstream searchTest("searchwords.txt.txt");
ReadFile(searchTest);
system("pause");
}
void Char(char letters)
{
cout << letters;// << endl;
}
void ReadFile(ifstream& infile)
{
if (!infile)
{
cout << "ERROR:";
cout << "Can't open input file\n";
}
else
{
infile >> noskipws;
while (!infile.eof())
{
char ch;
infile >> ch;
Char(ch);
}
}

I'm not too sure on how to place the info into an array or compare the items either
void SingleParameter(char letters);
void ReadFile(ifstream& infile);
int main()
{
ifstream infile("line.txt");
ReadFile(infile);
ifstream searchTest("searchwords.txt.txt");
ReadFile(searchTest);

I have created the ribbon resource and try to load the same using the following:-
m_wndRibbonBar.Create(this);
m_wndRibbonBar.LoadFromResource(IDR_RIBBON);where CMFCRibbonBar m_wndRibbonBar is declare in the header file as well.
But I can't create the same in dialog based application, it will work in SDI or MDI application.
I would like to create the ribbon control in a dialog based application.
Is there any possibility to do so, if not ; what are the alternatives for the same.
Thanks,

Hello,
I'm currently testing VS 2017 with our current Solutions which compiles with VS 2015 very well.
I installed parts of VS 2017 professional (WIN 8.1 SDk, no WIN 10 SDK, no VS 2015 Support).
When I open a 2015 solution I was asked to update the Projects to 8.1 SDK and Toolset v141 which I accepted.
But when I Try to build a C++ Project I get
Warning MSB8003 :
Could not find VCToolsInstallDir variable from the registry
TargetFrameworkVersion or PlatformToolset may be set to an invalid version number.
I searched in the registry and indded VCToolsInstallDir can not be found.
Which part of VS 2017 is missing ?
TIA

I made a simple example for function pointer like fowlloing.
#include <stdio.h>
void printname(char* first_name, char* last_name)
{
printf("full name is %s, %s\n", first_name, last_name);
}
int main()
{
void (*printname)(char*, char*) = &printname; // Error occur here!
(*printname) ((char*)"James", (char*)"Bond");
return 0;
}
However an compile error occur from the line displayed in bold.

Hi All
This is a bit of a long shot
I use a 3rd party language that can make external function call and could call SHBrowseForFolder however it cannot handle the callback function
I was wondering if anyone had a similar problem and had built a dll in c++ to wrap SHBrowseForFolder in a dll and provides an interface to a third party language so that it could use it successfully
Thanks in advance
In dlgfile.cpp, CFileDialog::ApplyOFNToShellDialog() is called every time my program calls CFileDialog::DoModal().
The first time I call CFileDialog::DoModal(), CFileDialog::ApplyOFNToShellDialog() properly calls IFileDialog::SetFileTypes().
The second time I call CFileDialog::DoModal(), CFileDialog::ApplyOFNToShellDialog() calls IFileDialog::SetFileTypes() again, gets E_UNEXPECTED, and crashes my program.
I'm not going to check if newer versions of Visual Studio fixed this. 10 was the new 6. A workaround is to set bVistaStyle to FALSE when calling the constructor.

Hello, suppose I have the following 3 files, I want to declare a variable instance of MyContextReactor class in call.cpp
MyClass.cpp
#include "function.h"
class MyContextReactor : public AcEdInputContextReactor { public: void beginGetPoint( const AcGePoint3d* pointIn, const char* promptString, int initGetFlags, const char* pKeywords);
....
private:
....
}
//my function
MyContextReactor::beginGetPoint...
...
Call.cpp
#include "function.h"
MyContextReactor cls;
my questions is:
in function.h file
do I have to declare all the function and variables of function.h again? (If so, I have to copy it twice?)
function.h
Is there any shorter method? please help me.#ifdef...
...
#endif
class MyContextReactor : public AcEdInputContextReactor { public: void beginGetPoint( const AcGePoint3d* pointIn, const char* promptString, int initGetFlags, const char* pKeywords);
...
};
