Direct Input compilation

[Drone38]

Can anybody explain me why the compiler can't make my programm.<br>Error :[Lieur Erreur] Unresolved external '_c_dfDIMouse' referenced from D:\PROGRAMMATION\C++\POKEMON\UNIT1.OBJ.<br>I have include dinput.h.<br><br>Look at this code :<br><br>&nbsp;&nbsp;&nbsp;&nbsp;HRESULT hr;<br>&nbsp;&nbsp;&nbsp;&nbsp;hr = DirectInputCreate( HInstance , DIRECTINPUT_VERSION, &g_pDI, NULL );<br>&nbsp;&nbsp;&nbsp;&nbsp;if ( FAILED(hr) )<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return hr;<br>&nbsp;&nbsp;&nbsp;&nbsp;hr = g_pDI-&gt;CreateDevice( GUID_SysMouse, &g_pMouse, NULL );<br>&nbsp;&nbsp;&nbsp;&nbsp;if ( FAILED(hr) )<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return hr;<br>&nbsp;&nbsp;&nbsp;&nbsp;hr = g_pMouse-&gt;SetDataFormat( &c_dfDIMouse ); // The error come from here...<br>&nbsp;&nbsp;&nbsp;&nbsp;if ( FAILED(hr) )<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return hr;<br>&nbsp;&nbsp;&nbsp;&nbsp;hr = g_pMouse-&gt;SetCooperativeLevel( hDlg,DISCL_EXCLUSIVE ¦ DISCL_FOREGROUND);<br>&nbsp;&nbsp;&nbsp;&nbsp;if ( FAILED(hr) )<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return hr;<br><br>Remark than I can't use all predifinded parameter :<br><br> c_dfDIKeyboard <br> c_dfDIMouse <br> c_dfDIMouse2 <br> c_dfDIJoystick <br> c_dfDIJoystick2<br>&nbsp;&nbsp;<br>I absolute need an anwer because in my game, I need to retrive the position of the mouse and the classical API don't work when you're under DirectX.<br>

&nbsp;&nbsp;&nbsp;&nbsp;An <i>unresolved external</i> error usually means that you have not included the proper header file. The compiler/linker is looking for <i>_c_dfDIMouse</i> but can't find it in the included files. Where is <i>_c_dfDIMouse</i> defined? Have you put that header in your program (e.g. <i>#include &lt;mouse.h&gt;</i>)?<br> <p>James P. Cottingham<br><a href=mailto: > </a><br><a href=

Yes I have include this file, but it doesn't work anyway

if header file is included then try to give the path of obj file. I think it could be a path problem.<br><br>Siddhartha Singh <p>Siddhartha Singh<br><a href=mailto:siddhu_singh@hotmail.com>siddhu_singh@hotmail.com</a><br><a href=siddhu.freehosting.net> </a><br>
