Dear advisor

The code

library aaaaa ;

Function Total(X, Y: Integer): Integer; stdcall;
begin
   x := ChoiceQuanTiTy(x,y) ;
   Total := x + y ;
end;

Function ChoiceQuanTiTy(X, Y: Integer): Integer; stdcall;
begin
   if X < Y then ChoiceQuanTiTy := X else ChoiceQuanTiTy := Y;
end;

exports
  Total,
  ChoiceQuanTiTy ;
begin
end.

[Error] Project2.dpr(5): Undeclared identifier: 'ChoiceQuanTiTy'

Please correct for me. How to use a function in the same library

Please show me the command to shutdow window. that command for shutdown depends on version of window ?

Or the command to close the active application on window.

Because i want comething to appear when they use my program but not register

library aaaaa ;

Function ChoiceQuanTiTy(X, Y: Integer): Integer; stdcall; forward;

Function Total(X, Y: Integer): Integer; stdcall;
begin
   x := ChoiceQuanTiTy(x,y) ;
   Total := x + y ;
end;

Function ChoiceQuanTiTy(X, Y: Integer): Integer; stdcall;
begin
   if X < Y then ChoiceQuanTiTy := X else ChoiceQuanTiTy := Y;
end;

exports
  Total,
  ChoiceQuanTiTy ;
begin
end.

You should 'consider on position'

Position is everything.   Another way, which gets more compliated still....


library aaaaa ;

uses
  Unit1;  //I can't be bothered to think of anything better.

begin
end;




unit Unit1;

interface

Function Total(X, Y: Integer): Integer; stdcall;
Function ChoiceQuanTiTy(X, Y: Integer): Integer; stdcall;

exports
  Total,
  ChoiceQuanTiTy;

implementation

Function Total(X, Y: Integer): Integer;
begin
   x := ChoiceQuanTiTy(x,y) ;
   Total := x + y ;
end;

Function ChoiceQuanTiTy(X, Y: Integer): Integer;
begin
   if X < Y then ChoiceQuanTiTy := X else ChoiceQuanTiTy := Y;
end;

end.


I can't think of any more variations on this theme.  geobul has already covered the others.

IT, Stop Being Called Into Every Meeting

Highfive is so simple that setting up every meeting room takes just minutes and every employee will be able to start or join a call from any room with ease. Never be called into a meeting just to get it started again. This is how video conferencing should work!

Increase question points to 40 and split them. The minimum amount of points which can be assigned to an expert is 20.

Guys... Please use the Result varuable...


library aaaaa ;

Function ChoiceQuanTiTy(X, Y: Integer): Integer; stdcall; forward;

Function Total(X, Y: Integer): Integer; stdcall;
begin
   x := ChoiceQuanTiTy(x,y) ;
   RESULT := x + y ;
end;

Function ChoiceQuanTiTy(X, Y: Integer): Integer; stdcall;
begin
   if X < Y then RESULT := X else RESULT := Y;
end;

exports Total, ChoiceQuanTiTy ;
begin
end.

Borland is different here from the Pascal standard simply because it's a bit more readable. If you use ChoiceQuanTiTy instead of Result, a reader might actually think you're calling the routine again, recursively...

To split points, you need to increase the points for this Q to 40 and split it. The minimum points any expert can get is 20 points. (But my remark is for free!)

my remark was for free too.   I decided not to point out the Result issue, so as not to confuse things.
