Yes. As long as nobody takes control of the primary buffer, all secondary DirectSound buffers should be mixed by the system. Works fine on XP and Vista I know for sure. Mark Mark Salsbery Microsoft MVP - Visual C++ :java:

If you do not want to use "loadlibrary" see other reply) 1) You cannot set a path for a DLL, you must either have your new DLL in the same directory as the DLL you are calling, or put it in the windows/system32 directory. 2) You need to link the lib file. Either add the lib file using project properties or add following to your source file #pragma comment(lib,"DllName.lib") 3) Add the header file for the DLL to your source file.

thx. it works. :)

Step 1. Ensure that IDC_EDIT1,IDC_EDIT2,IDC_EDIT3 are consecutive ID's ie 1001,1002,1003 Step 2. instead of 3 separate ON_EN_CHANGE's inside the ClassWizard part of the MESSAGE_MAP use on ON_CONTROL_RANGE outside of the ClassWizard part of the MESSAGE_MAP ON_CONTROL_RANGE(EN_CHANGE, IDC_EDIT1, IDC_EDIT3, OnChangeEdit1) Step 3. change the declaration of OnChangeEdit1 to void YourClass::OnChangeEdit1(UINT nIDCtl) see ON_CONTROL_RANGE[^]

Do you want to make edit controls with user select why you dont use of a int variable I had worked before but I think its possible that you use of them.

thx, it already works.
