C++ WINAPI super simple window docking 3x3

Hi, Need some support for positioning my dialogs. I can program, but no time to set my interface straight, I have a mess with my Dialogs popping everywhere ... If interested, please read below, and use in answer : "simple docking" (to delete all spam immediately) - I would like to divide my client area of my main window in 3x3 quadrants. - Then, when i call up a dialog, it should use the available 3x3 quadrant, starting from right-down and going up ... towards left-up. - Window handles are defined in map dialog_map<string,hWND> - I did read and study some docking software and libs, but way to complex for what i need. I need simple resizing dialogs and positioning. The Catch : - Resizing a window should allow to disappear another window and cover more than 1/9 space and for example take 2/9. (taking space of another window, and this counts as occupied). (info : - When a window is closes, it is just hidden, but does not occupy space) (info : - expanding goes only vertical, ... that's where i miss sometimes info in my dialogs) The BONUS : - Each dialog contains mostly only a text-box and sometimes some buttons for an action i need. If this could resize too a bit would be great. Basically, mainly the text window in his horizontal length. - It would also be very ok, if you define/need just 2 standard dialog type (one with only full edit-text box, one with text box and three buttons above or right of it ) The EXPECTATIONS : - a working C++ api example, with menu item that can choose for 10 dialogs. (all dialogs have a close cross in their top-right corner). - ?? i am not a great API programmer and i dont have time for this, but if I would do it then : * a class dialog_dog - containing info on visualized dialogs and there occupied positions within a 3x3 matrix - ?? The REWARD ... aaah ? - 30 euro, i think should be ok. Please motivate why if needed more. KEEP IT SIMPLE ! Thanks in advance for considering and thinking about. Regards, Hans
