It is annoying for VBA processor as it needs to fully qualify the object each time. This concept tells us to use [A1] rather than Range("A1") and Range("Stock Range")(3,4) rather than Range("Stock Range").
(Isn't it annoying for us too when some work or something is told us again and again? The point here to understand is minimum qualifying of an object by VBA processor. Cells(3,4) Use vb Null String instead of ""(2 double quotes) : vb Null String is slightly faster than "", since vb Null String is not actually a string, but a constant set to 0 bytes, whereas "" is a string consuming at least 4-6 bytes for just existence.
We might say, "VB does not use pointers", but it is not true.
"VB does not let you manipulate pointers" is more precise. If all we ever use are object pointers, how can we set the object itself to Nothing? When we set a reference to Nothing, something called the garbage collector kicks in.
For example: Instead of str Variable = "", use str Variable = vb Null String.
There are many ways to implement a garbage collector, but Visual Basic uses what is called the reference count method.
On the eve before Christmas, I'm writing this article on VBA code optimization for my blog readers as a gift. For example, a macro that required several seconds to complete in an earlier version of Excel may require several minutes to complete in a later version of Excel.
It contains both the knowledge and good practices which if followed and used effectively then it might put you in elite category of excellent VBA programmers. This problem may occur if the following conditions are true: * The VBA macro modifies the properties of many rows or columns.
Calculation = xl Calculation Manual Stop Events: Use Application.
You may turn off the automatic calculation using Application.
