How to delete function from DLL binary


How to delete function from DLL binary

To fix the issue you can do I've got a compiled dll file (dll binary) without source code. I have to delete some functions from this dll. Dll is written in C++. , Friends, here is solution works for me.
Solution
code :
?Func1@@YAHH@Z proc near    ;GetSquaredNumber

arg_0= dword ptr  8

push    ebp
mov     ebp, esp
mov     eax, [ebp+arg_0]
imul    eax, eax
pop     ebp
retn
?Func1@@YAHH@Z endp
__declspec(dllexport) int Func1(int x)    // GetSquaredNumber
{
    int y_res = 0;

    __asm
    {                           
        mov     eax, [x]
        push    ebp
        mov     ebp, esp        
        imul    eax, eax
        pop     ebp
        mov [y_res], eax
    }

    return y_res;
}

I think the issue was by ths following , How can I implement a function to delete an element in a binary search tree? This is my tree: , You should implement a function
code :
delMin :: Tree a -> (Tree a, a)
-- delete' n  deletes the node n and returns a modified BST
delete' :: Ord a => Tree a -> Tree a
delete' (Node _ l Leaf)  =  l
delete' (Node _ Leaf r)  =  r
delete' (Node _ l r)     =  let (r', min) = delMin r in
                              Node min l r'

Does that help Either the largest of the nodes to the left or the smallest of the nodes to the right will take it's place!
Simply put one of these where the deleted node was (and delete them from your previous position) and your tree will still be a valid binary search tree. Take a look at this example:
code :
    15
   /  \
  …    25
      /  \
     20  30
       \
        23

I wish this help you Basically i was only replacing the node with itself, but this can be solved by replacing the deleted node with the minimum element in the right subtree or the maximum element in the left subtree.
The function that works:
code :
treeNode * Delete(treeNode *node, int data)
{
    treeNode *temp;
    if(node==NULL)
      {
        printf("Element Not Found");
      }
    else if(data < node->data)
      {
        node->left = Delete(node->left, data);
      }
    else if(data > node->data)
      {
        node->right = Delete(node->right, data);
      }
    else
      {
    /* Now We can delete this node and replace with either minimum element 
               in the right sub tree or maximum element in the left subtree*/
        if(node->right && node->left)
          {
        /* Here we will replace with minimum element in the right sub tree */
            temp = FindMin(node->right);
            node -> data = temp->data; 
    /* As we replaced it with some other node, we have to delete that node */
            node -> right = Delete(node->right,temp->data);
          }
        else
           {
        /* If there is only one or zero children then we can directly 
                       remove it from the tree and connect its parent to its child */
            temp = node;
             if(node->left == NULL)
                    node = node->right;
             else if(node->right == NULL)
                    node = node->left;
            free(temp); /* temp is longer required */ 
            }
    }
    return node;

Delete node function will not delete certain nodes from a binary search tree

Delete node function will not delete certain nodes from a binary search tree

will be helpful for those in need The tree is sorted alphabetically the first letter of words. Some words I can delete, some I cannot. As in I try to delete it and nothing happens, but it still exits the deleteWord function. It will also get down to two words left in the tree and when I try to delete one of them, the program does nothing. It simply gives me a blank line which i cannot enter anything into; its stuck in a while loop somewhere but I cant figure out why. Sometimes I try to delete a word and instead of it being deleted, it is replaced by the data of another node and I have a duplicate node. I know theres a logic error in here but I cant find it. , edited the final else statement to read:
code :
else
        {
            cout << "else entered.\n";
            if(current -> data.getWord() < current -> parent -> data.getWord())
            {
                current -> parent -> left = NULL;
                current = NULL;
                found = true;
            }
            else if(current -> data.getWord() > current -> parent -> data.getWord())
            {
                current -> parent -> right = NULL;
                current = NULL;
                found = true;
            }
            else 
            {
                current = NULL;
                found = true;
            }
        }

fixed the issue. Will look into that further Hey I want to delete a node from my binary tree. I know a node cannot be deleted if it has both right and left children. So I have written code accordingly. But every time the program runs, it crashes. , Quick look:
