我在Btrieve中获取GetNextExtended(36)操作 时遇到问题。这里是一个返回状态码62呼叫:Btrieve GetNextExtended Status 62
intStatus = BTRCALL(B_GETNEXTEXTENDED, _
m_byteFilePosBlk, _
m_byteRecordBuffer(0), _
lngDataBufferLen, _
ByVal strKeyBuffer, _
intKeyBufferLen, _
m_intKeyNum)
做的代码搜索后,我发现很多网站,指出 代码表示DataBuffer中的一个错误,存储在m_byteRecordBuffer。 下面是存储在变量中的值:
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
我希望我只是失去了一些东西简单。任何帮助将不胜感激。
如果您没有过滤条件并且只获取一条记录,那么您不能只使用常规GETNEXT而不是GETNEXTEXTENDED ?在记录缓冲区中,尝试交换UC字符的位置。将'U'(85)置于位置2,将'C'(67)置于位置3. – Anna 2010-11-29 15:42:17
