I haven't been here for a long time. This time I will bring you some things.As we all know, the Julia set is an iterative algorithm, that is, the results are constantly put into algorithm computing, so that the results are constantly approaching the real value.For example, we use this algorithm for calculation pi; and e.The Julia set has many forms that consume a large amount of resources to produce results. We can use this algorithm to test computer performance.Because BitmapData is suppor

Keep the form at the beginning
You can use the setwindowpos function to set the position and status of a window. In this example, you can use this function to place a form on all forms so that it is always at the beginning.
Let's take a look at the definition and parameters of the setwindowpos function:
Before using the API function, you must first
