Which pointer do you use to resize a chart on excel?
C
What are the Name of mouse pointer shape and functions?
The upper-left pointing arrow pointer is a general-purpose pointer. It is used in most window areas for single-object selection and activation. The hotspot for the arrow pointer should be in the point of the arrow.You can optionally use an I-beam pointer in any Text component. It is used to change the location of the text insertion cursor and to perform actions on text. If the I-beam is used, it can be hidden during the time between any keyboard action and a mouse movement. This helps the user distinguish the I-beam pointer from the text insertion cursor, which can also be an I-beam. The hotspot for the I-beam pointer should be on the vertical bar of the I-beam about one-third up from the bottom.The X pointer can indicate when the pointer is outside of any application area. The hotspot for the X pointer should be where the lines intersect.The resize pointers indicate positions for area resize, and they remain during a resize operation. The direction of the arrow in the pointer indicates the direction of increasing size. The horizontal and vertical pointers indicate resize in either the horizontal or vertical direction. The diagonal pointers indicate resize in both the horizontal and vertical directions simultaneously. The hotspot for the resizing pointers should be on the elbow or the line at the position pointed to by the arrow.The hourglass pointer, a working pointer, indicates that an action is in progress in the area, and that the pointer has no effect in the area. While the hourglass pointer is active, all mouse button and keyboard events are ignored in the area. The hotspot for the hourglass pointer should be located at the center of the hourglass, although it should not be used for activation. The hourglass pointer can be used interchangeably with the watch pointer.The watch pointer, a working pointer, indicates that an action is in progress in the area, and that the pointer has no effect in the area. While the watch pointer is active, all mouse button and keyboard events are ignored in the area. The hotspot for the watch pointer should be located at the top of the watch, although it should not be used for activation. The watch pointer can be used interchangeably with the hourglass pointer.The 4-directional arrow pointer indicates a move operation is in progress, or a resize operation before the resize direction has been determined. During a move operation, the object, or an outline of the object should move to track the location of the pointer. During a resize operation, the pointer is used to indicate a direction for resizing. The 4-directional arrow pointer should change to the appropriate resize arrow when the resize direction is determined, either by crossing an object boundary with the pointer or by pressing a keyboard direction key. The hotspot for the 4-directional arrow pointer should be at the spot where the arrows intersect.The sighting pointer is used to make fine position selections. For example, in a drawing program it can be used to indicate a pixel to fill or the connecting points of lines. The hotspot for the sighting pointer should be at the spot where the lines intersect.The caution pointer is used to indicate that action is expected in another area before input can be given to the current area, and that the pointer has no effect in the area. While the caution pointer is active, all mouse button and keyboard events are ignored in the area. The hotspot for the caution pointer should be located at the center of the caution symbol, although it should not be used for activation.The question pointer is used to request an input position or component from the user. This is often used to input an object for interactive help. The user requests interactive help, then the question pointer is displayed to allow the user to indicate what position or component help is requested for. The hotspot for the question pointer should be at the bottom of the question mark.You can optionally use an arrow pointing to the upper-right corner to indicate a pending Menu action. This shape indicates that a Menu is popped up or pulled down and waiting for a Menu item to be activated or the Menu to be removed. The hotspot for this arrow pointer should be in the point of the arrow.
How is an embedded chart made smaller or larger?
Click on it, and use the mouse to grab the corner, sides, top or bottom to resize it.
How this pointer works in C plus plus?
The "this" pointer is a pointer to the instance of the object, with scope within a member function of that object. It is not always necessary to use it, as references to variables defined in the object will be implicitly prefixed with "this->", but it can resolve name scoping problems, and it can make the code more readable.
What is dangling pointer reference in c plus plus?
A dangling pointer (we also use the terms stray pointer and wild pointer) is created whenever we call delete on a pointer and then try to use the pointer without reassigning it.We can also create dangling pointers inadvertently by calling a rogue function that returns a pointer to an object that is local to the function we are calling. The object will fall from scope when the function returns so the pointer is left dangling.Note that there is no such thing as a dangling pointer reference. Pointers and references are not the same. A reference is merely an alias to an object -- it consumes no memory beyond the object it refers to. Whereas a pointer is a variable that may contain the address of an object, but it requires additional memory to do so (4 bytes on 32-bit architecture). Pointers may be NULL, references can never be NULL. Pointers to valid objects require indirection, references do not. References are the preferred method of accessing an object's members, not least because they are easier to work with.
Why do you use double star '' in initializing a variable in class?
The double star (**) notation is not specific to initializing a variable in a class. It is simply a double indirect reference to an object.float myFloat; // an objectfloat *myFloatPtr; // a pointer to an objectfloat **myFloatPtrPtr; // a pointer to a pointer to an objectmyFloat = 123.456; // initialize an objectmyFloatPtr = &myFloat; // initialize a pointer to an objectmyFloatPtrPtr = myFloatPtr; // initialize a pointer to a pointer to an objectmyFloat; // refer to an object*myFloatPtr; // refer to an object through a pointer**myFloatPtrPtr; // refer to an object through a pointer to a pointer*myFloatPtrPtr; // refer to the value of the pointer to the objectDouble pointer notation is used where the caller intends that one of its own pointers need to be modified by a function call, so the address of the pointer, instead of the address of the object, is passed to the function.An example might be the use of a linked list. The caller maintains a pointer to the first node. The caller invokes functions to search, add, and remove. If those operations involve adding or deleting the first node, then the caller's pointer has to change, not the .next pointer in any of the nodes, and you need the address of the pointer to do that.
What is a presentation pointer in a computer program?
A presentation pointer is a light (usually red) that you use so you don't have to touch the object the presentation is protuding of off.
What is an array of pointers to pointers?
A pointer is a variable that stores value of address of a variable. Since a pointer itself is a variable, it is allocated a memory location.Pointer to pointer means a pointer which points to the address of a pointer. In other words a pointer to a pointer has the address of the address of a variable.We can have pointers to int, and pointers to char, and pointers to any structures we've defined, and in fact pointers to any type in C, it shouldn't come as too much of a surprise that we can have pointers to other pointers. If we're used to thinking about simple pointers, and to keeping clear in our minds the distinction between the pointer itself and what it points to, we should be able to think about pointers to pointers, too, although we'll now have to distinguish between the pointer, what it points to, and what the pointer that it points to points.
Why you can not use this pointer in static functions?
Because this points to the current object, but static methods don't have a current object (actually this is definition of the static methods).
How can I change my Photos Background and resize photo?
How can I change my Photos Background and resize photo? Answer: Use Lunapic to resize, enlarge, shrink or scale an image instantly. Use the form above to choose a image file or URL. After uploading, choose the width or height of the image. You can also drag the corners of the image to resize it. In the future, use the menu above Edit -> Resize Image.
What are the advantages of pointers in a program?
A pointer is simply a variable that stores a memory address and that allows that memory to be dereferenced. Unlike a reference, which must always refer to the object assigned to it, a pointer can refer to any object of the pointer's type, including null. A null pointer is simply a pointer that does not refer to any object. In languages that do not support pass by reference (such as C), pointers must be used to pass objects to functions. The pointer is passed by value, but the value is a memory address, which is the same as passing the object at that address. In languages that do support references (such as C++), references are useful when you need to guarantee an object exists because a reference can never be null. However, when passing an object to a function as an optional parameter, you must use a pointer because pointers can be null. Programmers must test pointers to ensure they are non-null before attempting to dereference them. References do not need to be tested; if a reference exists, it must refer to an object in memory.
