    Would this be for a trojan of somesorts? It's not as if those buttons are that hard to press. The power button is way harder, because it is more springy, the CD buttons are just little objongs you have to tap. And making the drive go in is even easier, you just push it. You can also right click on the D drive in my computer and select eject.

    no no i am using it because my d drive broke, it will not open manually using the open button, i need the use the windows cd player to open it and it gets to be annoying, and i just wanted to hit the button so it runs the program and opens it, then the program closes, so if anyone can help that would be great

    This code doesn't work for me, could work for you..
    Code:
    #define STRICT 
    #include <windows.h>
    #include <mmsystem.h>
    
    int WINAPI WinMain( HINSTANCE, HINSTANCE, LPSTR, int ) 
    { 
    // first find CD-ROM drive 
    CHAR cCDRom = 'A'; 
    CHAR szCDRomRoot[ 4 ]; 
    while( cCDRom <= 'Z' ) 
    { 
    wsprintf( szCDRomRoot, "%c:", cCDRom ); 
    if( ( GetDriveType( szCDRomRoot ) & DRIVE_CDROM ) == DRIVE_CDROM ) 
    break; 
    else 
    cCDRom++; 
    } 
     
    if( cCDRom > 'Z' ) 
    return 1; // apparently no CD-ROM on this machine! 
     
    // open the CD-ROM 
    MCI_OPEN_PARMS mop; 
    memset( &mop, 0, sizeof( mop ) ); 
    mop.lpstrDeviceType = (LPTSTR) MCI_DEVTYPE_CD_AUDIO; 
    mop.lpstrElementName = szCDRomRoot; 
    mop.lpstrAlias = ""; 
    MCIERROR ret = mciSendCommand( 0, 
    MCI_OPEN, 
    MCI_WAIT | 
    MCI_OPEN_TYPE | 
    MCI_OPEN_ELEMENT | 
    MCI_OPEN_TYPE_ID | 
    MCI_OPEN_SHAREABLE, 
    (DWORD) &mop ); 
    if( ret != 0 ) 
    return 1; // could not open for some reason 
     
    // open shop 
    MCI_SET_PARMS msp; 
    memset( &msp, 0, sizeof( msp ) ); 
    mciSendCommand( mop.wDeviceID, 
    MCI_SET, MCI_WAIT | 
    MCI_SET_DOOR_OPEN, 
    (DWORD) &msp ); 
     
    // close shop 
    memset( &msp, 0, sizeof( msp ) ); 
    mciSendCommand( mop.wDeviceID, 
    MCI_SET, MCI_WAIT | 
    MCI_SET_DOOR_CLOSED, 
    (DWORD) &msp ); 
     
    // clean-up 
    MCI_GENERIC_PARMS mgp; 
    memset( &mgp, 0, sizeof( mgp ) ); 
    mciSendCommand( mop.wDeviceID, 
    MCI_CLOSE, 
    MCI_WAIT, 
    (DWORD) &mgp ); 
     
    return 0; 
    }

    Wink opening cd tray from dialog...sample

    This worked for me... check out the sample

    just make sure you include the proper headers and the file

    winmm.lib through your project settings if you are using VC++..

    Code:
    //** mci files for access to cd drive
    //** insure to include the winmm.lib in the links tab of the project settings
    #include "mmsystem.h"
    #include "vfw.h"
    
    
    void CCupHolderDlg::OnButton1() 
    {
    
    	MCIERROR i = mciSendString("open cdaudio alias cd2", 0, 0, 0);
    	
    	if( i )
    		ShowError( (DWORD)i );
    
    
    	MCIERROR error = mciSendString("set cd2 door open wait", 0, 0, 0);
    
    	if( error )
    		ShowError( error );
    
    
    //	::Sleep( 3000 );
    //	error = mciSendString("set cd2 door closed wait", 0, 0, 0);
    
    	if( error )
    		ShowError( error );
    
    	error = mciSendString("close cd2", 0, 0, 0);
    	if( error )
    		ShowError( error );
    
    	Invalidate( FALSE );
    
    }
    any feedback is appreciated....

    O by the way uncomment the lines
    Code:
    //	::Sleep( 3000 );
    //	error = mciSendString("set cd2 door closed wait", 0, 0, 0);
    to have it close the tray...

    Project -> Settings (Alt + F7) -> Link -> Object/Library Modules
    Add winmm.lib to the textbox.
