如何在Windows上使用sqlite3和masm32

Question

由於我必須在彙編器中編寫一個訪問Sqlite3數據庫的小型庫，因此我開始搜索如何使用sqlite3.dll。我已經找到了一種方法來做到這一點在fasm（我必須使用masm32的許多原因，這不會有助於解決問題，它只是一種必然）通過cinvoke和引用看起來不可用的庫。
我基本上想知道的是，我是否可以在masm中做類似的事情，或者我需要通過GetProcAddress單獨調用每個函數的地址。

Answer 1

爲什麼不呢？它很簡單，如下所示：

.486 
.model flat, stdcall 
option casemap:none 

include \masm32\include\masm32.inc 
include \masm32\include\kernel32.inc 
include \masm32\include\user32.inc 
include sqlite3.inc 

.data 
szSQLDB   db "MyDB.db3", 0 
szRandQuery  db "SELECT * FROM Quit ORDER BY RANDOM() LIMIT 1;", 0 

.data? 
hDBase   dd ? 

.code 
START: 
    invoke sqlite3_open, offset szSQLDB, offset hDBase 

    call GetQuitMsg 

    invoke sqlite3_close, hDBase 

    invoke ExitProcess, 0 

GetQuitMsg proc 
local ppStmt 

    invoke sqlite3_prepare_v2, hDBase, offset szRandQuery, -1, addr ppStmt, 0 
    invoke sqlite3_step, ppStmt 
    invoke sqlite3_data_count, ppStmt 
    .if eax !=0 
     invoke sqlite3_column_text, ppStmt, 0 
     invoke MessageBoxA, 0, eax, 0,0   
    .endif   
    ret 
GetQuitMsg endp 
end START 

我使用makefile，Geany作爲我的編輯器。該zip包含測試數據庫sqlite3.inc，但不包含sqlite3.dll只是解壓縮文件，將sqlite3.dll放到項目目錄中，您將可以輕鬆完成。我也不使用MS鏈接，而是使用GoLink，因爲它不需要導入庫，但是如果你必須使用MS鏈接，我在這裏有一個SQLite導入庫。

薩拉姆，

這是我的示例代碼:)

它將創建名爲 'file.db' 的數據庫文件，創建一個名爲 'DBI' 表，然後將數據爲三行。插入數據三次後，它將顯示MessageBoxA的數據。作爲標題的nID和作爲文本的szName。

有樂趣我的代碼:)，

請添加包括LIB和BIN環境MASM安裝的路徑。

例子：

INCLUDE = C：\ MASM32 \包括

LIB = C：\ MASM32 \ LIB

BIN = C：\ MASM32 \ BIN

並確保有當您在命令提示符處鍵入設置時，上面的路徑是。

Wassalam。
