I wanted to ask if it is possible to create a MessageBox where the user can enter values. E.g. how many workers he wants to insert etc.
Currently I could only implement buttons like “Yes” or “Ok”.
I would be very grateful for an answer.
That is no longer a MessageBox. You will need to create your own dialog box (window) with custom content and logic.
Also VC doesn’t generally use dialog boxes, “commands” that can have settings in a panel are preferred.
