Excel macro screenupdating not working
We rarely fire an event for each cell we're changing via code. Enable Events to tell VBA processor whether to fire events or not.For example: Instead of str Variable = "", use str Variable = vb Null String.Release memory from object variables: Whenever we create an object in VBA, we actually create two things -- an object, and a pointer (called an object reference).Behind the scenes, VB still makes extensive use of pointers. This little piece of software tries to determine whether or not an object should be destroyed.There are many ways to implement a garbage collector, but Visual Basic uses what is called the reference count method.
You can increase the speed of some procedures by keeping screen updating turned off.
When we combine multiple lines using colon into one line, we're reducing the number of fetch cycles the processor must go through.
Our Suggestion: This change will bring minor difference in time due to faster processors today.
When VB interprets the last line(where we generally sets our objects to Nothing), it will remove the existing reference.
At this point, if the object has no more references, the garbage collector will destroy the object and deallocate all its resources.
