Sharepoint online: mass deletion of Outlook events using MS Flows

My requirement is to delete all Outlook events using MS Flows.

I have tried the steps mentioned below.

select -> Outlook 365
-> add, update or modify Outlook events
-> select calendar -> Calendar
-> ID __> in the place of Id. I have provided the subject's name (may be wrong)

yes condition
yes -> remove event v2
no -> Notification

But no luck

Delete cell based on the deletion of another cell

I want to bounce on a thread that I saw before. In Clear cell based on the modification of another cell.

In that thread, the question was about how to delete a corresponding cell when another cell was modified. How do I delete a corresponding cell when another cell is empty?

Python: When creating a creation object using an @classme (cls) method, it automatically executes the deletion method. Why is this happening?

class Clientes:
    cod = False
    nome = None
    saldo = False
    n_clientes = 1
    total_clientes = {}

    def __init__(self):

    def __del__(self):

    def novo_cliente(cls):
        if Clientes.n_clientes == 10:
            print('Limite de clientes atingido!')
            while True:
                nome = input('Nome: ')
                if nome.isalpha()==False:
                    print('O nome deve ser composto apenas por letras! =D')

            while True:
                saldo = input('Primeiro deposito: ')

                if saldo.isnumeric()==False:
                    print('Saldo deve conter apenas nĂºmeros!')
                    saldo = int(saldo)
                except AttributeError:

            Clientes.total_clientes(Clientes.n_clientes) = (nome, saldo)
            Clientes.n_clientes += 1
    def atualizar_cliente(cls):
    def del_cliente(cls):
        print('executando sozinho')

cliente1 = Clientes()

deletion: can the deletion of an uninherited object be exploited more than once for code execution?

By assigning priority to an error, we had an internal discussion about whether deleting an object in C ++ more than once can cause code execution if the object pointer may be damaged. For objects that have a virtual destroyer, the answer seems to be obvious here.

However, what is not obvious is whether this could be exploited for code execution when a deleted object is a standard type (that is, long), an array or an instance of a class that does not have a virtual table.

Can this situation lead to code execution in any existing popular implementation?

Deletion: Is it possible to recover secure deleted data using hardware?

Is it possible to restore data using advanced hardware recovery such as DeepSpar Disk Imager or ACE Laboratory – PC-3000 Express System?

I used the CCleaner cleaning tool (Complex – 7 Passes) to clean my hard drive, to test I used several famous recovery software, they couldn't restore any data, but I read in some articles that hardware recovery systems are much more complicated algorithms They can dig deeper and all your files appear. How true is that?

data structures: parallel deletion and scrolling in a linked list without blocking

I am not sure about the security of removal in a linked list. I have seen the problem posed by a parallel insertion and elimination (resulting in the loss of the insertion) and proposed solutions to that problem. That makes a lot of sense. However, nowhere have I seen him mention that an unfortunate crossing in parallel with a deletion can cause problems. For example, if we have the linked list:

A -----> B -----> C* ------> D

and a process (process 1) goes through it, currently points to C (as indicated by the *), however, before process 1 the next C pointer, another process (process 2) removes C and frees its memory. Then, when process 1 tries to read the next C pointer, it will read the uninitialized memory (which could be used to store an int, for example) and, therefore, could point to an invalid location and cause a segmentation failure when referring to that pointer.

How can this problem be avoided?

8 – Link field deletion parameters for external links

I have a content type that uses the link field that I configured only for external URLs. When I put a website URL with more than 1 query, it will not represent the second part of the query.

Example of what it should represent:

Finish rendering as:

Removing the last ?aid=8674

I tried to set the field settings to use Both internal and external links As mentioned in this similar question, however, this did not solve anything for me. Every time there is more than 1 query with the URL, delete everything except the first one.

Would anyone have found this before or would they know a way to solve this? For this type of content in particular, we link users to external sites and need these URLs to authenticate through the multiple parameters that we set in the link field.

c – The correct result of the deletion cannot be seen outside the method

I was trying to eliminate the node with two children, but when I was printing all the elements of the resulting tree one by one to see if I was getting the correct result, I was receiving a segmentation error. I tried to print the elements of the resulting tree inside the tree and it seemed fine. Only when I try to print the tree outside the removal method.

I was passing the root reference and other variables required to modify them.

struct node {
  void * key; // key
  void * value; // value
  struct node * left; // left child
  struct node * right; // right child
struct node * map_tree_del(struct node * tree,  struct node * ele, int(compareTo)(void * x, void * y), size_t * size) {

  if( compareTo(ele->key, tree->key) < 0 & tree->left != NULL) {
    tree->left = map_tree_del(tree->left, ele, compareTo, size);
  else if (compareTo(ele->key, tree->key) > 0 & tree->right != NULL) {
    tree->right = map_tree_del(tree->right, ele, compareTo, size);
  else {

    if(ele->left == NULL & ele->right == NULL) { // zero children
      return NULL;
    else if (ele->left != NULL & ele->right == NULL) {
      return ele->left;
    else if (ele->right != NULL & ele->left == NULL) {
      return ele->right;
    else if (ele->left != NULL & ele->right != NULL){

      struct node * replacer = map_tree_max_element(ele);

      ele->key = replacer->key;
      ele->value = replacer->value;
      ele->left = ele->left;

      printf("%dn", *(int*)replacer->key);
      printf("%dn", *(int*)ele->value);

      printf("BOSS %dn", *(int*)tree->key);

      map_tree_del(tree, replacer, compareTo, size);





Test code

int main () {

  struct node tree = {0};
  tree.left = NULL;
  tree.right = NULL;
  size_t size = 0;

  int a,b,c,d,e,f,g;
  int aa,bb,cc,dd,ee,ff,gg;

  a = 5;
  b = 2;
  c = 3;
  d = 1;
  e = 4;
  f = 6;
  g = 7;

  aa = 55;
  bb = 22;
  cc = 33;
  dd = 11;
  ee = 44;
  ff = 66;
  gg = 77;

  struct node a_ = {&a, &aa, NULL, NULL};
  struct node b_ = {&b, &bb, NULL, NULL};
  struct node c_ = {&c, &cc, NULL, NULL};
  struct node d_ = {&d, &dd, NULL, NULL};
  struct node e_ = {&e, &ee, NULL, NULL};
  struct node f_ = {&f, &ff, NULL, NULL};
  struct node g_ = {&g, &gg, NULL, NULL};

  map_tree_add(&tree, &a_, compareTo, &size);
  map_tree_add(&tree, &b_, compareTo, &size);
  map_tree_add(&tree, &c_, compareTo, &size);
  map_tree_add(&tree, &d_, compareTo, &size);
  map_tree_add(&tree, &e_, compareTo, &size);
  map_tree_add(&tree, &f_, compareTo, &size);
  map_tree_add(&tree, &g_, compareTo, &size);

  map_tree_del(&tree, &b_, compareTo, &size);

  printf("seg fault happens here %dn", *(int*)tree.left->key);

  return 0;


It gives me a security flaw when I try to print the left root node. I should get 4 after 2 is deleted, but all I get is a segfault.

network connection: the Windows 10 route keeps coming back after a while every time I delete it with the route deletion, how can I delete the route forever?

Initially, I had a raspberry pi / pi2 on my network that surpassed my DHCP server router and offered IP addresses and, due to some default options, Windows was perhaps receiving the IP address of the DHCP pi2 server as its gateway. I solved it by adding the specific gateway router option to my dhcpd configuration on the raspberry pi.

But apparently on my Windows 10pc .200, I still receive this apparent manual route (regardless of whether it is wifi or lan) to one of my PCs. Call it with the netmask and the gateway (address pi2).

So when I do the route impression it gives: 26

So because of this I can't connect / ping from my Windows 10pc to .100 ip

It will work after routing delete -p but then it will be added again.

netsh ipv4 interface show route:
Without manual 1 10

I searched the registry and didn't see any persistent path there (Computer HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Services Tcpip Parameters PersistentRoutes)

How can I find out where / how this ghost network route continues to return?

c ++ – Single-threaded task scheduler with type deletion and enabled for assignors

I did a task scheduler to practice the assignors and type deletion. With my project, you can delay the execution of any callable (functions (using std::ref), lambdas …) in time inserting it into a TaskScheduler, and giving a std::chrono::time_point (You can also have a task called several times by giving a point (std::chrono::duration) and optionally a call number)).

This project does not use threads, so to perform the tasks called, you must call TaskScheduler::update (probably in a main loop), which will then call the tasks if necessary. I only have basic knowledge about multiple threads, so if you have any advice to do TaskScheduler Sure thread, I'm interested.

In addition, I have implemented type deletion (so any claimant can fit in the TaskScheduler) so I am interested in comments about the type security of this implementation.

Here is the code:



class TaskTraits {
    using clock = std::chrono::system_clock;

    void cancel() noexcept { _fun = nullptr; }
    void execute() { if (_fun) (*_fun)(*this); }
