我无法让 GetNextExtended(36) 操作在 Btrieve 中工作。这是返回状态码 62 的调用： 

    intStatus = BTRCALL(B_GETNEXTEXTENDED, _
                        m_byteFilePosBlk, _
                        m_byteRecordBuffer(0), _
                        lngDataBufferLen, _
                        ByVal strKeyBuffer, _
                        intKeyBufferLen, _
                        m_intKeyNum)

在对代码进行搜索后，我发现许多网站指出该代码表明数据缓冲区中存在错误，存储在 m_byteRecordBuffer 中。以下是存储在该变量中的值：

m_byteRecordBuffer(0)    16    'These two bytes indicate the total size of'  
m_byteRecordBuffer(1)    0     'data buffer' 

m_byteRecordBuffer(2)    67    'These two bytes indicate the characters 'UC''
m_byteRecordBuffer(3)    85

m_byteRecordBuffer(4)    0     'These two bytes indicate the maximum reject' 
m_byteRecordBuffer(5)    0     'count, which if set to 0 defaults to 4,095' 

m_byteRecordBuffer(6)    0     'These two bytes indicate the number of terms'
m_byteRecordBuffer(7)    0     'which has been set to zero'

m_byteRecordBuffer(8)    1     'These two bytes indicate the number of' 
m_byteRecordBuffer(9)    0     'records to return'

m_byteRecordBuffer(10)  1     'These two bytes indicate the number of fields'
m_byteRecordBuffer(11)  0     'to extract'

m_byteRecordBuffer(12)  2     'These two bytes indicate the length of the'
m_byteRecordBuffer(13)  0     'field to extract'

m_byteRecordBuffer(14)  1     'These two bytes indicate the field offset'
m_byteRecordBuffer(15)  0

我希望我只是缺少一些简单的东西。任何帮助将不胜感激。

在记录缓冲区中，尝试交换 UC 字符的位置。
将“U”（85）放在位置 2，将“C”（67）放在位置 3。
