Back in August 2007,\n\nI promised to post a program the following day<\/a>\nbut it appears that I never did.\nOops.\nI discovered this as I went through my “things to blog about” pile\nand figured better late than never.\nThough five years late is pretty bad.\n<\/p>\n

\nHere’s a program which fills a combo box with some strings.\n<\/p>\n

\n#include <windows.h>\n#include <windowsx.h>\nstatic LPCTSTR rgpszList[] = {\n    TEXT(\"Austria\"),\n    TEXT(\"Belgium\"),\n    TEXT(\"Bulgaria\"),\n    TEXT(\"Cyprus\"),\n    TEXT(\"Czech Republic\"),\n    TEXT(\"Denmark\"),\n    TEXT(\"Estonia\"),\n    TEXT(\"Finland\"),\n    TEXT(\"France\"),\n    TEXT(\"Germany\"),\n    TEXT(\"Greece\"),\n    TEXT(\"Hungary\"),\n    TEXT(\"Ireland\"),\n    TEXT(\"Italy\"),\n    TEXT(\"Latvia\"),\n    TEXT(\"Lithuania\"),\n    TEXT(\"Luxembourg\"),\n    TEXT(\"Malta\"),\n    TEXT(\"Netherlands\"),\n    TEXT(\"Poland\"),\n    TEXT(\"Portugal\"),\n    TEXT(\"Romania\"),\n    TEXT(\"Slovakia\"),\n    TEXT(\"Slovenia\"),\n    TEXT(\"Spain\"),\n    TEXT(\"Sweden\"),\n    TEXT(\"United Kingdom\"),\n};\nINT_PTR CALLBACK DlgProc(HWND hdlg, UINT uMsg, WPARAM wParam, LPARAM lParam)\n{\n    switch (uMsg) {\n    case WM_INITDIALOG:\n        for (int i = 0; i < ARRAYSIZE(rgpszList); i++) {\n            SendDlgItemMessage(hdlg, 100, CB_ADDSTRING, 0,\n                               (LPARAM)rgpszList[i]);\n        }\n        return TRUE;\n    case WM_COMMAND:\n        if (GET_WM_COMMAND_ID(wParam, lParam) == IDCANCEL) {\n            EndDialog(hdlg, 0);\n        }\n        break;\n    }\n    return FALSE;\n}\nint WINAPI WinMain(HINSTANCE hinst, HINSTANCE hinstPrev,\n                   LPSTR lpCmdLine, int nShowCmd)\n{\n    DialogBox(hinst, MAKEINTRESOURCE(1), NULL, DlgProc);\n    return 0;\n}\n\/\/ scratch.rc\n#include <windows.h>\n1 DIALOG 50, 50, 185, 98\nSTYLE DS_MODALFRAME | WS_POPUP | WS_CAPTION | WS_DLGFRAME | WS_SYSMENU\nBEGIN\n    COMBOBOX 100,7,40,150,300,CBS_DROPDOWNLIST | CBS_SORT | WS_VSCROLL\nEND\n<\/pre>\n
\nRun this program and start typing:\n“S”-“L”-“O”-“V”-“E”…\nHey, look, the combo box is performing incremental search and once\nyou hit the “E”, it selected Slovenia, the first item in the list\nwhich begins with the letters S-L-O-V-E.\n<\/p>\n
\nWait a few seconds, and try it again.\nThis time, type “S”-“P”, and hey look, it selected Spain.\nYou didn’t have to go through all those other “S” countries to get to it.\n<\/p>\n
\nIf you hit F4 to open the combo box and then type\n“S”-“L”-“O”-“V”-“E”,\nobserve that there is a tiny vertical line that tells you where\nyou are in the incremental search string.\n<\/p>\n
\nAs I noted some time ago,\nthe incremental search resets after\n\nfour times the double-click time<\/a>,\nor two seconds by default.\n<\/p>\n
\nNote<\/b>:\nThe “things to blog about” pile has over 2000 items in it,\nso there really isn’t much need for a Suggestion Box,\nbut I open it up once every few years just for show.<\/p>\n","protected":false},"excerpt":{"rendered":"
