ASP File_Get_Contents and File_Put_Contents

As I've become more of a PHP developer than an ASP developer, one thing I've noticed is that it is 10x easier to read/write text files with PHP. Simply use file_get_contents() and be done. ASP isn't so nice. But it can be done, so I'm creating those for simplicity here:

<%
Function File_Get_Contents(strFile)
	' Remote File
	If Left(strFile, 7) = "http://" Or Left(strFile, 8) = "https://" Then
		Set objXML = Server.CreateObject("Microsoft.XMLHTTP")
		' Use this line if above errors
		'Set objXML = Server.CreateObject("MSXML2.ServerXMLHTTP")
		objXML.Open "GET", strFile, False
		objXML.Send()
		File_Get_Contents = objXML.ResponseText()
		Set objXML = Nothing
	' Local File
	Else
		Set objFSO = Server.CreateObject("Scripting.FileSystemObject")
		Set objFile = objFSO.OpenTextFile(strFile, 1)
		File_Get_Contents = objFile.ReadAll()
		Set objFile = Nothing
		Set objFSO = Nothing
	End If
End Function

Function File_Put_Contents(strFile, strContents, blnAppend)
	If blnAppend Then
		intMode = 8
	Else
		intMode = 2
	End If
	Set objFSO = Server.CreateObject("Scripting.FileSystemObject")
	Set objFile = objFSO.OpenTextFile(strFile, intMode, True)
	objFile.Write(strContents)
	Set objFile = Nothing
	Set objFSO = Nothing
End Function
%>

Of course this file_get_contents doesn't support remote URLs, but it can easily be added.

EDIT: I just added remote URL support.

Classic ASP: More Efficient Database Recordset, GetRows() XoiseRecordset

I’ve created what I believe to be a more efficient recordset object for traversing rows returned from a database query. I implemented all methods/properties that I feel make sense to implement. There’s definite room for improvement, but it’s a good start. My reasoning for creating this is that I like the functionality of using recordsets (via Server.CreateObject("ADODB.Recordset")), but there is a HUGE drawback in that it is horrible on the database. The Server.CreateObject approach makes a database call every time a EOF, BOF, or a traversal method (ie. MoveNext, MovePrevious, etc.) is called.

My fix is to use the GetRows() method to return it as a multidimensional array and just implement my own class with the same (or similar) functionality. There is also an advantage to using this Recordset over just plain using the GetRows() method. I went ahead and implemented a way to extract the column names from the query, which allows you to grab the information using the column name, instead of the index of the array (ie. objRS("Column_Name")). You may also access the data using the column index if you prefer. Note that I haven’t implemented support for "SELECT * FROM Tbl…" syntax, so you’ll HAVE to use the index for this.

There is one main usage difference to note. Rather than opening the recordset with .Open SQL_String, Connection_Object, you must individually update the .Conn and .SQL properties. I’ll most likely change this if there is enough interest and I create a newer version. If I do that, I’ll most likely provide cache support.
