Someone has just upgraded one of my old systems to three-tier.
There seems to be a serious bottle-neck between the middle tier (Midas) and
the back-end (Interbase).
At the moment they are still using BDE components.
Having never used Midas in anger, I am not much help.
Does anyone know of any
It's been a while (Delphi 4 infact) and a different company.
Can anyone tell me who the NZ distributor for Delphi is? Contact details
etc?
Thanks,
Phil.

1stly. Did the system originally use a file based DB like Paradox. If the answer
is yes, is the new app using TTables or TQueries. This is the first bottleneck
and relates to C/S developement in general.
There are several other things that can cause this, and they are not necessarily
related
G'Day All,
If I have something like:
TMyBaseComponent = class(TComponent)
private
FMyProp : string;
FOnMyEvent : TNotifyEvent;
published
property MyProp : string read FMyProp write FMyProp;
property OnMyEvent : TNotifyEvent read FOnMyEvent write
FOnMyEvent;
end;
TMyDescendantComponent =
Easy,
use abstraction ..
Do
this instead .. (However if you cannot change your base class you
arebasically stuffed ... ).
eg
TMyBaseComponent =
class(TComponent)private FMyProp : string;
FOnMyEvent : TNotifyEvent;
protected
procedure SetMyProp( const
Value: String ); virtual;
procedure
Donovan asked:
1. Determine when MyProp is changed so that TMyDescendantComponent
can take some specialised action
The main way to achieve this is to modify the base component to use a
SetMyProp to stire the new value into the FMyProp, and either have this
SetMyProp procedure virtual so that
If you
have written TMyBaseComponent change it to :
TMyBaseComponent =
class(TComponent)private FMyProp : string;
FOnMyEvent : TNotifyEvent;
protected
procedure
SetMyProp(Value: string); virtual;
published property MyProp : string read
FMyProp write SetMyProp; property

Which MIDAS connection method are they using Sockets, DCOM, WebConnection?
Sockets is the fastest. If sockets then check that the SCKTSVR has the
resolve
host names set off.
Sockets. - I dont think it has resolve hostname turned off tho.
Turning it off will make it way better on
thanks for that.
The problem seems to be that when the ctrl is held down, it doesnt fire the
keypress or keyup events.
Strange.

That's right, neither does Alt or Shift or Caps lock - but you can get their
state if required when another key is pressed in combination with them.

Correct, CTRL is passed as one of the flags, it is V you are trapping.

Delphi is long long way from protecting you from dealing with the Win32 API - you
need the win32 SDK help files as

Thanks guys.
In summary :-
1. All the usual problems of changing from ISAM to SQL
2. BDE threading not an issue if each user has a seperate connection
3. Sockets is fastest connection method (I dont think the stalling is in the
connect so I dont think the host resolution has any bearing)
4.

I wonder if the Midas caching of the master dataset is forcing full
population of all the child datasets.
Unless Campbell has changed it, yes, it does :)
One of the datasets also has a couple of blob fields so that could also be
causing overwork.
Not to the degree that this is, AFAIK.

The diskfree procedure takes a numeric value as its parameter. 0 for the
first hdd (C:) 1 for second (d:) etc.
