Hi to all!

I am working on the following piece of code:

-----------------------------------------------------
#define TXDEVICE_API extern "C" __declspec(dllexport)

int (*Txdevice_init)();

void __fastcall TForm1::Button1Click(TObject *Sender)
{ HINSTANCE hndr;

  hndr = LoadLibrary("Txdevice.dll");

  if (!hndr)
  {
    Edit1->Text = "DLL Loading Error";
    return;
  }

  Txdevice_init = (int (*)(void))GetProcAddress(hndr, "Txdevice_init");

  if (!Txdevice_init)
  {
    Edit1->Text = "DLL GetProcAddr Error";
    return;
  }

  // go on working ...
}
-----------------------------------------------------

I am pretty sure the "Txdevice.dll" does contain the routine
"Txdevice_init"; in spite of that the instruction:

Txdevice_init = (int (*)(void))GetProcAddress(hndr, "Txdevice_init");

always returns zero.
Is there something wrong in my code?
Thanks in advance.

Henry
