How do use the TRegistry.ReadBinary thing

[N/A]

I can read/write strings and integer no probs, but when it comes to binary (i.e. IP address) I don't know what to do with it.



I know nout about buffers, pointers etc, so if some one could write an example of how to retrieve and write data in binary it would be mucho appreciated!

Here's a quick example:



procedure ReadBinary( ... ); * * * * * * * * * * * * * * * * * * * * * aRootKey *: String * * );

var

* *aKey * * * * *: String;

* *aName * * * * : String;

* *aDataSize * * : Integer;

* *aDataType * * : TRegDataType;

* *aBuffer * * * : Pointer;

begin

* *aKey *:= '...'; //Insert Key Here

* *aName := '...'; //Insert Value Name Here

* *if ( aRegistry.OpenKey( aKey, FALSE ) = TRUE ) then

* *begin

* * * *if ( aRegistry.ValueExists( aName ) = TRUE ) then

* * * *begin

* * * * * *{ Gather data information for the key/value }

* * * * * *aDataSize := aRegistry.GetDataSize( aName );

* * * * * *aDataType := aRegistry.GetDataType( aName );

* * * * * *

* * * * * *if ( aDataType = rdBinary ) then

* * * * * *begin

* * * * * * * *GetMem *( aBuffer, *aDataSize );

* * * * * * * *FillChar( aBuffer^, aDataSize, 0 );

* * * * * * * *aRegistry.ReadBinaryData( aName, aBuffer^, aDataSize );

* * * * * * * *... //Use the data

* * * * * * * *FreeMem ( aBuffer, *aDataSize );

* * * * * *end;

* * * *end;

* *end;

end;

You don't have to check the data type if you don't want to, but it's a safe thing to do.

Basically you just have to allocate the memory at the pointer location. *Then use the data and free the memory. *You could use a static buffer if you like.

Sorry mate but I don't really understand all that.



I want to read the IP address from registry, then put the address in an edit box, then edit it, and save back in binary!



PLEASE HELP !

Send me the key and value names in the Registry

and I'll post an example.

hi, Id like a copy of the code too,

Basically I am trying to read IP address and Default gateway under windows NT and possible wirte back too
