DX9 EnumAdapterModes question

I''m converting a program from the book Real-Time Rendering Tricks and Techniques in DirectX from DX8.1 to DX9. I''ve sorted everything apart from this problem. PROTOTYPE long EnumerateModes(D3DDISPLAYMODE *pModes, long ModeCount); //---------------------------------------------------------- // Name: EnumerateModes() // Desc: Gets the number of display modes available. //---------------------------------------------------------- long Application::EnumerateModes(D3DDISPLAYMODE *pModes, long ModeCount) { //Get the actual number of available modes long Count = g_pD3D->GetAdapterModeCount(D3DADAPTER_DEFAULT); //If they asked for more than what is available, only give //them what is available. if (ModeCount > Count) ModeCount = Count; //Loop through the available modes, filling the array until //it is full. for (long ModeIndex = 0; ModeIndex < ModeCount; ModeIndex++) { g_pD3D->EnumAdapterModes(D3DADAPTER_DEFAULT, ModeIndex, &(pModes[ModeIndex])); } //Return the actual number available, in case they want to //ask for more. return Count; } This function worked no problem with 8.1 however now I get the following errors: - c:\program files\microsoft visual studio\myprojects\vertexshader\application.cpp(312) : error C2660: ''GetAdapterModeCount'' : function does not take 1 parameters c:\program files\microsoft visual studio\myprojects\vertexshader\application.cpp(324) : error C2660: ''EnumAdapterModes'' : function does not take 3 parameters I understand partially why I''m getting the 2nd error because EnumAdapterModes has changed to a D3DFORMAT in DX9. However I am totally stumped why I get the 1st error. I mean it worked, compiled no problem in DX8.1?? Any help really appreciated. Thanks and Happy New Year Paul.
