Dynamic menus

electronicman_x

I'm trying to implement a dynamic menu system to my program. Currently, i can add and remove the items from the menu, and make the menu items run code that i've premade. for example i can add "section 1" to a section menu, while associating ID_SECTION_1 to the command in the menu. This will call my OnSection1() code when this command is executed. I want this to be boundless (i.e. i dont want to have to make code for OnSection2, OnSection3, OnSection4... , or the strings in the string table, and so on.) I can currently bind each new menu item to the same id, for example section 1, section 2, and section 3 all run the OnSection() command which is bound to ID_SECTION. What i cannot do, is figure out how to determine which of the 3 i called. I would like to basically get the location of the last menu choice i picked, so if section 2 is in the second spot on the menu, i want to know this when i call OnSection(). Any ideas?

why dont u store the currently displayed option on the menu as a numeric index somewhere and use a switch staement in the code to determine what to do?

Many options will be showing, and i basically need to record the actual text that shows up in the menu. I cannot save the index value when i set the menu text, because i do not know which item will be chosen. I want the menu text simply to help me figure out which one i actually chose. For example File Edit Sections ->Section 1 I do something and create 3 more sections at runtime modifying the menu. Now the menu looks like this Sections ->Section 1 ->Section 2 ->Section 3 ->Section 4 Each Menu choice is bound to ID_SECTION. ID_SECTION corresponds to OnSection() In my code: void OnSection() { int section; // I need to fill the section variable with // the index of the item i picked from the menu // since all of them have the same ID. If(section==1) handle section 1 If(section==2) handle section 2 If(section==3) handle section 3 If(section==4) handle section 4 } Hopefully this helps. Thanks.

You should be able to use GetCurrentMessage() and interrogate the wParam/lParam values to get the actual command ID of the menu option selecetd.
