Hi,
please help me, how to use the TRegistry class. The help file contains no information
about using this class.
I need read the text value of VemaRoot property in the HKEY_LOCAL_MACHINESoftwareVema
key
Thanks

Check if your help file is updated since this component is documented from
many time ago.

#include "WinReg.api"
WITH OBJECT TRegistry():Create()
:Root := HKEY_LOCAL_MACHINE
IF :OpenKey( "SoftwareVema"
cText := :GetString( "VemaRoot", "MyDefaultValue" )
:CloseKey()
ENDIF
END

José,
it seems, your example is not complete.
in the line
> IF :OpenKey( "SoftwareVema"
is somthing missing.
I put 2 edit boxes on the form, getting the key name from oEdit1 and the desired item name
from oEdit2.
I'm using the next code to test the TRregistry class:
---------------------------------------------
METHOD Button1Click( oSender ) CLASS TForm1
LOCAL oReg, cString,nError,aKeys
WITH OBJECT oReg := TRegistry():Create()
:Root := HKEY_LOCAL_MACHINE
IF nError := :OpenKey( ::oEdit1:Value) > 0
cString := :GetString( ::oEdit2:Value, "MyDefaultValue" )
aKeys := :EnumKeys()
MessageBox(Self,"Error code: " + TRANSFORM(:nLastError,"999") + CRLF +;
"Number of items:" + TRANSFORM(LEN(aKeys),"999"))
:CloseKey()
ELSE
MessageBox(Self,"Error opening Registry Key: " + TRANSFORM(nError,"999"))
ENDIF
END
::oLabel1:cText := cString
---------------------------------------------
My problem:
I tried many keys from my Registry, the result is always the same
- cString is "MyDefaultValue"
- LEN(aKeys) is zero
Any advise?

And the :nLastError is always 1.

Gejza,
I have just tested this example and it works as expected:
---
#include "WinReg.api"
METHOD Button1Click( oSender ) CLASS TForm1
LOCAL cName
WITH OBJECT TRegistry():Create()
:Root := HKEY_LOCAL_MACHINE
IF :OpenKey( "SoftwareMicrosoftWindowsCurrentVersion" ) == 0
cName := :GetString( "ProductName" )
:CloseKey()
ENDIF
:Destroy()
END WITH
MsgInfo( cName )
RETURN Nil
---
Check it and let me know.

José,
your code doesn't works for me. The value "ProductName" doesn't exist in Registry on my
computer, I used ProductId and the result is empty cName.
May be the problem is somwhere in my computer?
My project is attached, the oButton1 on TForm1 tests this class.

The code at line 93 in HlavneOkno.prg is:
IF nError := :OpenKey( ::oEdit1:Value) > 0
and should be:
IF nError := :OpenKey( ::oEdit1:Value) == 0
Note that OpenKey() returns 0 if ok.
