用InStr函数 FOR EXAMPLE IN MSDN This example uses the InStr function to return the position of the first occurrence of one string within another.Dim SearchString, SearchChar, MyPos SearchString ="XXpXXpXXPXXP" ' String to search in. SearchChar = "P" ' Search for "P".' A textual comparison starting at position 4. Returns 6. MyPos = Instr(4, SearchString, SearchChar, 1) ' A binary comparison starting at position 1. Returns 9. MyPos = Instr(1, SearchString, SearchChar, 0)' Comparison is binary by default (last argument is omitted). MyPos = Instr(SearchString, SearchChar) ' Returns 9.MyPos = Instr(1, SearchString, "W") ' Returns 0.
FOR EXAMPLE IN MSDN
This example uses the InStr function to return the position of the first occurrence of one string within another.Dim SearchString, SearchChar, MyPos
SearchString ="XXpXXpXXPXXP" ' String to search in.
SearchChar = "P" ' Search for "P".' A textual comparison starting at position 4. Returns 6.
MyPos = Instr(4, SearchString, SearchChar, 1) ' A binary comparison starting at position 1. Returns 9.
MyPos = Instr(1, SearchString, SearchChar, 0)' Comparison is binary by default (last argument is omitted).
MyPos = Instr(SearchString, SearchChar) ' Returns 9.MyPos = Instr(1, SearchString, "W") ' Returns 0.
而且InStr也有我所说的把 回车+换行 当做两个字符的问题。Putao:

不知为何,发给你的信总说被拒收,怎么办?
逐字节处理就像分割文件一样,用数组Byte()来做。
