Problems in a DLL loading a second DLL.

[prebbe]

I have simplified this code a little bit so it would be easier to see:

*********************************
library lea;

uses
ShareMem,
SysUtils,
Classes,
Dialogs,
Windows;

const
cLines = 10;
cLetters = 30;

function TrInitTransportDriver(s: PChar):integer; stdcall; external 'Transport.dll';
function TrSetDevice(i: Integer):integer; stdcall; external 'Transport.dll';

function WriteToDisplay(var data: string):boolean; export;
begin
TrSetDevice(0);
TrInitTransportDriver('UsbDevice.ini');
TrSetDevice(0);
end;

Exports
WriteToDisplay

{$R *.res}

begin
end.
************************************

Ok. The problem is that when i run this code and the function WriteToDisplay, the 'TrSetDevice(0)'-code is executed as i could expect. But when i come to the next line a problem occurs. In the debugger i jump from the code up to the top where TrInitTransportDriver is defined(just as expected). And at the next step i suddenly jump all the way to 'end;' in the code in the exe. (At the bottom of where the quoted dll is dynamically loaded).

Anyone?

I just checked GetLastError and the result was: '2' which means something about file not found, so i guess that this error has nothing to do with my code, but is an error from something else. Aboslutely all my files are in one single folder. I have checked with "Dependencies Walker" that my dlls have all dependencies needed.

Is 'UsbDevice.ini' in the same folder as 'Transport.dll'?
