wlan compiled code returns error and i need to specify the password for the ssid

By -

I have this code right here I am using mingw to compile and I am running windows XP. When I run the output executable it gives me error prompt about the application..

Do I set everything correctly ? How do I set the SSID password for it to connect ? Also I want to know if I am using the correct network interface to connect (I have an external wifi adapter)..

I got the code from this link any help is very much appreciated..

//#define _WIN32_DCOM
#define _WIN32_WINNT 0x0600
#include <stdio.h>
#include <windows.h>
#include <conio.h>
#include <objbase.h>
#include <rpcsal.h>
#include <objbase.h>
#include <wlanapi.h>


int main(){
    
    PDOT11_SSID pSsid;
    strcpy(pSsid->ucSSID, "SUPERONLINE-WiFi_24811");
    pSsid->uSSIDLength = 25;
     
    HANDLE wlanHandle;
    unsigned long nv;
    WlanOpenHandle(1, NULL, &nv, &wlanHandle);

    DWORD dwResult = 0;
    WLAN_CONNECTION_PARAMETERS cp;
    memset(&cp, 0, sizeof(WLAN_CONNECTION_PARAMETERS));

    cp.wlanConnectionMode = wlan_connection_mode_profile;
    cp.strProfile = NULL;
    cp.dwFlags = 0;
    cp.pDot11Ssid = pSsid;
    cp.pDesiredBssidList = 0;
    cp.dot11BssType = dot11_BSS_type_any;

    PWLAN_INTERFACE_INFO_LIST pIfList = NULL;
    PWLAN_INTERFACE_INFO pIfInfo = NULL;

    // only use the first wifi interface
    dwResult = WlanEnumInterfaces(wlanHandle, NULL, &pIfList);
    pIfInfo = (WLAN_INTERFACE_INFO *)&pIfList->InterfaceInfo[1];

    if (dwResult == ERROR_SUCCESS)
    {
       dwResult = WlanConnect(wlanHandle, &(pIfInfo->InterfaceGuid), &cp, NULL);

       if (dwResult == ERROR_SUCCESS)
       {
           printf("Connected..\n");
          //connected = true;
       }
    }
    
    return 0;
}

This is the error I get:

enter image description here

Edit: I have made it this far to the code below.. But still I can not assign the value to PDOT11_SSID struct.. It seems the struct has UCHAR array yet I can't assign.. Here is the link

PDOT11_SSID pSsid;
UCHAR arr[22] = { 0 };
//memset(pSsid->ucSSID, '\0', 32); //this causes the same error too

memcpy(
arr,
(unsigned char[]){ 'S','U','P','E','R','O','N','L','I','N','E','-','W','i','F','i','_','2','4','8','1','1' },
sizeof(arr)); //memcpy to arr struct works..

ULONG len = 22;
pSsid->uSSIDLength = len;
memcpy(pSsid->ucSSID, arr, sizeof(arr)); // this line fails still..

Edit: I ran with -Wall -Wextra -pedantic -Werror Like David mentioned and with the code segment below:

PDOT11_SSID pSsid;
memset(pSsid->ucSSID, '\0', 32); //fails

I got this error

enter image description here

yet if I initialized with

PDOT11_SSID pSsid = { 0 };

or

PDOT11_SSID pSsid = NULL;

It compiled but I got the crash image above I used to get.. Important to note that memset(pSsid->ucSSID, '\0', 32); causes the crash as well. I can know this by commenting out each line and compiling/running again.

This is a burden since I am yet to figure out how to add SSID password with wlanapi.h so help for these will be much appreciated for me to move on forward.

Fyi: I use basic gcc to compile gcc.exe wlan.c -lwlanapi. If there is any working solution code to connect to an ssid with the ssid and password using wlanapi, a link to that is also appreciated.

Wlan connect from msdn is this link.. I can't see any security parameters, how do I set the password of the SSID I want to connect to ?

Hibernate Search - Elasticsearch with JSON manipulation

By -
Elasticsearch with JSON manipulation Elasticsearch ships with many features. It is possible that at some point, one feature you need will not be exposed by the Search DSL. To work around such limitations, Hibernate Search provides ways to: Transform the HTTP request sent to Elasticsearch for search queries. Read the raw JSON of the HTTP response received from Elasticsearch for search queries. Direct changes to the HTTP request may conflict with Hibernate Search features and be supported differently by different versions of Elasticsearch. Similarly, the content of the HTTP response may change depending on the version of Elasticsearch, depending on which Hibernate Search features are used, and even depending on how Hibernate Search features are implemented. Thus, features relying on direct access to HTTP requests or responses cannot be guaranteed to continue to work when upgrading Hibernate Search, even for micro upgrades (x.y.z to x.y.(z+1)). Use this at your own risk.

Spring Elasticsearch Operations

By -
Elasticsearch Operations Spring Data Elasticsearch uses two interfaces to define the operations that can be called against an Elasticsearch index. These are ElasticsearchOperations and ReactiveElasticsearchOperations. Whereas the first is used with the classic synchronous implementations, the second one uses reactive infrastructure. The default implementations of the interfaces offer: Read/Write mapping support for domain types. A rich query and criteria api. Resource management and Exception translation. ElasticsearchTemplate The ElasticsearchTemplate is an implementation of the ElasticsearchOperations interface using the Transport Client. @Configuration public class TransportClientConfig extends ElasticsearchConfigurationSupport {   @Bean   public Client elasticsearchClient() throws UnknownHostException {                      Settings settings = Settings.builder().put("cluster.name", "elasticsearch").build();     TransportClient client = new P
