pb passing numeric variable by reference to a DLL function

[tandreys]

when I pass numeric variable by reference to a function in an external DLL, the modified value are not visible in TC.

In the example below, after the call to the function, the value of nrow and ncol is still 0.

Passing a structure, a string (via dll.new("lpstr")) is working fine.



any idea?

thanks



LONG WINAPI GridGetSelectedCell(HWND hWndGrid, unsigned long* row, unsigned long* col)

{

 *row=2;

 *col=3;

 return 1;

}



in TC (7.52)

[jscript]

MY_DLL.DefineProc("GridGetSelectedCell",vt_i4,vt_byref | vt_ui4,vt_byref | vt_ui4,vt_hresult );

mydll = DLL.Load("D:\\auto\\current\\Tools\\Syb_qa\\Debug\\syb_qa.dll","MY_DLL")

...

var nrow=0;

var ncol=0;

mydll.GridGetSelectedCell(SGridWnd.Handle,nrow,ncol);

//I'm expecting nrow=3, ncol=2

Hi,



JScript doesn't support passing parameters by reference.
