Hello, i am writing a 3d program using DirectX. Now i want to play a piece of sound with DirectSound, but the initilization was not accomplished. the code i have written below, .... CoInitialize(NULL); if (FAILED( hResult = CoCreateInstance( CLSID_DirectMusicLoader , NULL, CLSCTX_INPROC, IID_IDirectMusicLoader8, (void**) &pLoader))) { return SOUNDERROR_MUSICLOADER; } if (FAILED( hResult = CoCreateInstance( CLSID_DirectMusicPerformance, NULL, CLSCTX_INPROC, IID_IDirectMusicLoader8, (void**) &pPerformance))) { return SOUNDERROR_MUSICPERFORMANCE; } .... the initial of DirectMusicLoader succeed, but wenn DirectMusicPerformance is initilized, it returned failure. Does anyone knows how can i solve the problem? thx anyway. mwolf122

I put some CEdit to the dialog, use the same function OnChangeEdit1, when the context of edit box is changed, such as, ON_EN_CHANGE(IDC_EDIT1, OnChangeEdit1) ON_EN_CHANGE(IDC_EDIT2, OnChangeEdit1) ON_EN_CHANGE(IDC_EDIT3, OnChangeEdit1) the problem is, I can not decide which edit box has called the function, How can I get the ID for it?

to Hamid, unfortunately, i havent got sendmessage in the link you gave. I can assign a ID and a function before the CEdit is created, and use UDN_DELTAPOS (ID, OnEditChange(). then by creating the CEdit, I can set the same ID for the CEdit. the problem is, before the programm running, i cant decide how many CEdit should be created, so I have no idea how many IDs should be assigned in my program.

hallo, in order to display and change a date list written in a txt file, seveal CEdit and CSpinCtrl should be dynamic created. The amount for the set of Editbox and SpinCtrl should be dynamic decided, according to the count of date set. CSpinCtrl and CEdit has the same behavior. I cant set the Message using ClassWizard, How can I dynamic set the Message for the CEdit and CspinCtrl? I have tried, in the Class, a Message Map UDN_DELTAPOS (ID, OnEditChange()). I set all the CSpinCtrl with the same ID. In this way, when any CspinCtrl changes, the function OnEditChange() will be called, but i can not recognize which one has been clicked. does anyone who has a solution? thanks ;) mwolf

thx, it already works.
