Scan Registry es muy doloroso! Linares Help US

[EduardoAlicante]

For solve some problem with hardware configuration, i go to study fivewin and it's registry istruction.
Fivewin haven't istruction for solve this problem.
Harbour idem
xHarbour idem.
Only for a sample of the problem:
I get a list of installed printer:
I go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Printers
i get the subkey present on this item.
for every subkey i get some value for obtain a list of printer installed.
This is only a sample, there are many case for to get registry key and subkey.

Like a scan a DBF invoice file, i searc a key of file head, in file rows, i read all item with key of invoice, for calculate the total for samples.

I see how to in visual basic this is possible. And i have a program of scan a registry. But i work with Fivewin, and do no love make a program in too language for to work.

Fivewin + xharbour is very good, but some part are not complete.
How to?

I'm not totally sure what you are looking for. For the list of installed printers problem, try this function. Do notice that the function returns an array:

Function GetPrinters()
Local aPrinters := {}, cText, cToken := Chr(15)

// Passing no second param or passing ZERO to GetProfString()
// grabs entire section in .ini file. Each printer is separated by a
// null char (Chr(0)) and a CRLF. We just strip them out

cText := StrTran( StrTran( StrTran( ;
GetProfString( "Devices", 0 ), Chr(0), cToken ), Chr(13) ), Chr(10) )

aPrinters := Array( Len( cText ) - Len( StrTran( cText, cToken ) ) )

AEval( aPrinters, {| cPrn, nEle | aPrinters[ nEle ] := StrToken( cText, nEle, cToken ) } )

Return aPrinters
