VB acts as a popular visual programming language, its powerful interface design function saves a lot of time for program designers. However, in the face of neatly arranged in a large amount of the same control, although it can be arranged during design, it is inevitable that it is accidentally moved in debugging, or later adds to some. So some people use statements to regulate in the program, and their hardships are imaginable (the author's deep experience), even if the position is ranked, its index attribute (.tabindex) is often chaotic. Can you Let the control of the control, index properties are automated? After some thinking, the author finally found a good solution and successfully applied to the registry modifier it developed. Example: New project, put a Frame control frame1, then add 4 check box in Frame1, pickBox2, checkbox3, checkbox4 add: ArrangeChildren frame1 running results for 4 check boxes The equal spacing is arranged in its container FRME1. In the design window, you can adjust their upper and lower positions, and will be neatly arranged in the upper and lower order in which they are designed, and their index sequence is arranged in a large arrangement. (Index order, do you know - let your program support keyboard operations). Dividing, you can increase anything in the container, reduce the number of controls (the type is the same), and they can be neatly arranged after running, so that one is eternal.
The following is the specific sub-process code public subrurse 'Father is the container control' function: (1) Sort the TabINDEX value of the sub-control within the container control 'Sort by: from top to bottom (.top) The value is made of small to large), TabINDEX is small to large '(2) any control of the sub-control in the container control DIM Children () AS Control' is the control in the container.
