In asp, especially in cms systems that need to produce static files, it is often necessary to judge, create, and delete some files. Here are some of them, which basically meet the basic needs.
Copy the code code as follows:
'======================================
'Get file suffix
'======================================
Function Get_Filetxt(ByVal t0)
Dim t1
IF Len(t0)<2 Or Instr(t0,".")=0 Then Get_Filetxt=False:Exit Function
t1=Split(t0,".")
Get_Filetxt=Lcase(t1(Ubound(t1)))
End Function
'======================================
'Pure code to read any file
'======================================
Function LoadFile(ByVal t0)
IF Len(t0)=0 Then Exit Function
IF Sdcms_Cache Then
IF Check_Cache("LoadFile_"&t0) Then
Create_Cache "LoadFile_"&t0,LoadFile_Cache(t0)
End IF
LoadFile=Load_Cache("LoadFile_"&t0)
Else
LoadFile=LoadFile_Cache(t0)
End IF
End Function
Function LoadFile_Cache(ByVal t0)
Dim t1,stm
On Error Resume Next
IF Len(t0)=0 Then Exit Function
t1=Empty
Set Stm=Server.CreateObject("Adodb.Stream")
