c++ - How to send these items in the combo box -


i have created combo box in program. have function named add() adds files drive specified.

i searched google on how list of drives present in computer, , found this:

dword var1 = 100; wchar storevalue[100]; dword drives = getlogicaldrivestrings(var1, storevalue); (int = 0;i < 100;i++) {     return 0; }

i want add drives present in computer combo box, function can add files specified drive. how can this? quiet tricky beginner.

i aware easier when create browse drive wish in combo box.

getlogicaldrivestrings fills buffer double-null terminated array of strings. can iterate through this, stopping when first character of "next" string null.

wchar_t szdrives[max_path]; if (getlogicaldrivestrings(max_path, szdrives)) {     wchar_t* pdrive = szdrives;     while (*pdrive)     {         // pdrive          // jump next         pdrive += wcslen(pdrive) + 1;     } }

now "do pdrive" can in case add string combo box:

        sendmessage(hwndcombo, cb_addstring, 0, reinterpret_cast<lparam>(pdrive));
