i am novice in both Delphi and Visual C++.

but i have to use VC function in Delphi.

(i use delphi 6 edition.)

how can i use this function (written in VC , GEO3D.dll)

 XIS_EXPORT BOOL X3DGTF_SetPlaneTableInfo( HGTFWND _GTFWnd, char*
_strTableName )

 XIS_EXPORT BOOL    X3DGTF_Invalidate( HGTFWND hGTFWnd )

XIS_EXPORT void X3DGTF_SetPlane( HGTFWND _hGTFWnd, BOOL _bflag, BOOL
_bUpdate )

              XIS_EXPORT BOOL    X3DGTF_Invalidate( HGTFWND hGTFWnd )

i tried to use like this

//in declare unit
  function X3DGTF_SetPlaneTableInfo( hGTFWnd:HGTFWND ; strTableName:Pchar )
: BOOL; cdecl; external GEO3D;

// in main unit
  BoolsetPlane:=X3DGTF_SetPlaneTableInfo( hGTFWnd ,pchar('Plane'));  // 486
Line

but it cannot work..
error message like below.
//[Error] Main.pas(486): '(' expected but ',' found

how can i do..

Sorry for my poor english....
