I'm trying to get the list of all installed softwares, and i want to do it using the Windows APIs only.
This is my code..
#include "stdafx.h"
#pragma comment(lib,"msi.lib")
#include <Windows.h>
#include<iostream>
#include "Msi.h"
using namespace std;
int _tmain(int argc, _TCHAR* argv[])
{
TCHAR *liProBuf = new TCHAR[39];
UINT liVal = MsiEnumProducts(0,liProBuf);
cout << liProBuf;
getchar();
return 0;
}
The above code uses the function MsiEnumProducts which returns the Global Unique Identifier(GUID) ,which is the unique identifier for the product.But after this i don't know how to to get the name of the product using this GUID.
How can this be done.

I've been working on a credential provider and I've been debugging it through logging. Recently learned about CredUIPromptForWindowsCredentials() API to be able to invoke it from other than login screen or remote desktop connection. The only way at this time I can seem to get my credential to display is to set the last param to CREDUIWIN_SECURE_PROMPT. I've tried various schemes of the flags with no luck. My CP works, that's not the problem. Problem is easier debugging. Only once have I had to go to rescue mode when I made my laptop unbootable. ;) The problem with using the CREDUIWIN_SECURE_PROMPT flag is that then I don't have access to the debugger because login takes over the screen and I can't get back to my debugger. I suppose the only workaround would be to remote debug on another machine with this API, but I'd prefer not to hassle with that.
My CP is registered at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\Credential Providers\{55157584-ff0f-48ce-9178-a4e290901663} and the default property is "MyCredProvider" (for this example). (GUID, prop name changed to protect the guilty. Also ignore LsaString where bad things would happen on a copy--of which I'm not doing.)
Any way to get my custom CP without using the secure prompt?

I am using VS 2019 and the C++ Language Standard is set to Default which I assume is C++ 11?
I have the following constructor of a class in a header file:
input_parser(int& argc, wchar_t** argv)
{
for (auto i = 0; i < argc; ++i)
{
this->tokens_.emplace_back(argv[i]);
}
};
To call the methods argv parameter I am creating an array of wchar_t in the following manner:
std::wstring command_line = L"-m \"F-14RHV\" -s \"BIT|Flir\" -d";
auto buffer = new wchar_t[command_line.length() + 1];
wcsncpy_s(buffer, command_line.length()+1, command_line.c_str(), command_line.length() + 1);
const auto inputs = input_parser(argc, &buffer);
delete[] buffer;
Inside the constructor the first pass when argc == 0 is fine but I get an access violation when argc == 1.
Okay so some programmer dude was correct and here is how I have to do it after I figure out how to split the string by spaces!
Here is the final answer:
#include <string>
#include <sstream>
#include <algorithm>
#include <iostream>
#include <iterator>
std::wstring text = L"-m \"F-14RHV\" -s \"BIT|Flir\" -d";
std::wistringstream iss(text);
std::vector<std::wstring> results((std::istream_iterator<std::wstring, wchar_t>(iss)),
std::istream_iterator<std::wstring, wchar_t>());
Using a vector is going to make this process MUCH easier. I will probably change the other side to use a vector now.
Thanks for the help.
The following code fails to compile with 1.58 while it was compiling with 1.46. I guess it's a type conversion issue, but I can't make it right.

recursive_directory_iterator beg = recursive_directory_iterator(".");
recursive_directory_iterator end = recursive_directory_iterator();

std::function<bool (path const & path)> fileFilter =
[](path const & path) -> bool {
return is_regular_file(path);
};
std::vector<path> paths;
copy(files | filtered(fileFilter), std::back_inserter(paths));
// works:

// also works:
//for(recursive_directory_iterator it = beg; it != end; ++it){

}

Edit
Filed as https://svn.boost.org/trac/boost/ticket/11228.
This seems to be a bug introduced somewhere since Boost 1.55. Using boost 1.55 this compiles ok.
It could be this bug: https://svn.boost.org/trac/boost/ticket/10989
boost_1_57_0/boost/concept_check.hpp|210 col 13| error: conversion from ‘boost::iterators::single_pass_traversal_tag’ to non-scalar type ‘boost::iterators::forward_traversal_tag’ requested
The filtered adaptor requires the input to be forward_traversal tag. But recursive_directory_iterator only promises single_pass_traversal tag:
BOOST_RANGE_CONCEPT_ASSERT((
Convertible<
BOOST_DEDUCED_TYPENAME ForwardIteratorConcept::traversal_category,
forward_traversal_tag
>));
WORKAROUND
You can disable concept checks for now: -DBOOST_RANGE_ENABLE_CONCEPT_ASSERT=0:

Any help is highly appreciated.
Check to see if the log file is in the current working directory of the process, rather than the specified file collector target directory ("log" in your sample code). Additionally, you will probably want to specify a directory for the sink "file_name" pattern.
As "JQ" notes, don't expect to see any logging post-exception.
I have one application which reads user default locale in Windows Vista and above. When i tried calling the API for getting User default Locale API is crashing. Below is the code, It will be helpfull if any points the reason
#include <iostream>
#include <WinNls.h>
#include <Windows.h>
int main()
{
LPWSTR lpLocaleName=NULL;
cout << "Calling GetUserDefaultLocaleName";
int ret = GetUserDefaultLocaleName(lpLocaleName, LOCALE_NAME_MAX_LENGTH);
cout << lpLocaleName<<endl;
}
You need to have lpLocaleName initialized to a buffer prior to calling the API. As a general consensus, if an API has a LPWSTR data type parameter, call malloc or new on it first, to the desired length, in this case, LOCALE_NAME_MAX_LENGTH. Setting it to NULL and passing it to the API function is a guaranteed way to crash!
Hope this helps,
Best regards,
Tom.
In addition to the previous answers, you should also be aware that you can't print a wide string with cout; instead, you should use wcout.
So:
#include <iostream>
#include <WinNls.h>
#include <Windows.h>
#define ARRSIZE(arr) (sizeof(arr)/sizeof(*(arr)))
using namespace std;
int main()
{
WCHAR_T localeName[LOCALE_NAME_MAX_LENGTH]={0};
cout<<"Calling GetUserDefaultLocaleName";
int ret = GetUserDefaultLocaleName(localeName,ARRSIZE(localeName));
if(ret==0)
cout<<"Cannot retrieve the default locale name."<<endl;
else
wcout<<localeName<<endl;
return 0;
}
I believe you need to initialise lpLocaleName to an empty string of 256 chars (for example) then pass the length (256) where you have LOCALE_NAME_MAX_LENGTH
