DSQUERYPARAMS

構造体
📘 Microsoft Learn (日本語) · English
サイズx64: 56 バイト / x86: 48 バイト

サイズ=各フィールドのバイト数(x64/x86 で異なる場合は x64/x86 と併記)。x64/x86 列=フィールドのバイトオフセット(HSPで dupptr / lpoke / wpoke 等に使用)。

フィールド

iColumnsINT4+20+16aColumns配列に含まれる列定義の個数。
dwReservedDWORD4+24+20予約フィールド。0を設定する。
aColumnsDSCOLUMN24+28+24結果表示の列を定義するDSCOLUMNの可変長配列。

HSP用 定義

HSP3.7/3.8 は構造体機能が無いため4byte整数配列(dim)+peek/poke で操作(32/64bitでサイズ・位置が異なる場合はタブで分割)。IronHSP は NSTRUCT(#defstruct/stdim/->)で32/64bit共通。
