Hi,
have you tried using more but shorter buffers ? Ok this will cause a higher use of the write functions - but shorter buffers have of course shorter delay in change.
But wait - You are using 1024 Sample Buffers ? I guess for a game you are using 44,1k/16bit/mono ? That means the total play-time of the buffer is about 23ms. Therefor a change needs at least this time to appear. On the other side this time can only appear as a short chorusing effect because the time is to short for human hearing to notify 2 seperate sounds. I think you should not notify a delay. Maybe you have a great preformance loss in your wave-mixer ? You should check it out.
To raise up speed you should not use the wave-event (don`t know if you did). Better use the WaveOutProc-CALLBACK.
Then you should put the output routine in a seperate thread.
Hope it helps

Hi,
I would recommend having a quick look at the FMOD sound library. It's been around for a while, so is quite mature and stable. Have a look at www.fmod.org for further details.
Hope this helps,
Regards,
Craig.

Hi! I'm coding a dialog based application, and when the user take some actions
(an specific button, or keyword) my application must show a document based in some data that I take from a database. this Document must have a toolbar and menu resources. I have the datbase connection, but I don't know how show this data in the sdi?

If I was writing this, I would start with an SDI application, but show dialogs until I needed to bring up a view, then hide/show the view as needed.

Hello, the codegurus around the world. 
As long as we focus on the dialog based application, we had better call
another exe file with SDI inside OnInitDiaog.
However, if we want to get the data from the dialog in SDI, we need additional code.
So, as the other poster told us, it is easy to create SDI and call the dialog before
SDI application shows.
However, if this dialog deals with hiding and showing SDI at any time,
I have to examine the code. 
Have a nice day!

Basically your CWinApp derived class can hold a pointer to the SDI main frame, which can be hidden, shown and moved using ShowWindow, SetWindowPos and MoveWindow. It can be accessed from a dialog class.

Hello, the codegurus around the world.
I doubt a little about your approach.
Even though we put on the creation of SDI on CWinApp::InitInstance(),
CMyDialog object already gets the address of m_pMainWnd.
At run time, we can't change the main object (Dialog or SDI) to m_pMainWnd.
Or, you're talking about another approach?
I mean, there are several approaches to satisfy with the requirement.
So, I am simply curious about your idea.
Have a nice day!

I'm not sure what you think I meant, but I am talking about starting a new SDI application, and moving the dialog based code into it. On reflection, I'd start the dialog in CMainFrame, not in CMyApp, but the core of the idea is that the app is SDI, but the user does not see the SDI window until it is needed, instead they see the dialog boxes. I don't see any other way to get the Doc/View architecture working for one part of a dialog based app. An SDI app can easily lauch dialog boxes, but I don't know of a mechanism for a dialog app to lauch SDI windows, and dialog boxes most certainly cannot have a Windows toolbar.

mmmm I'm gonna prove what u say, the problem it's the data that must be shared between SDI and Dialog. Well I've got to probe it and I'll tell u. Thanks, anyway I'll really apreciate if u have information on that

newbie question created a dialog program but as you get deeper into the prog you end up with a lot of old dialog boxes in the background. the question is can i/how do you get rid of them i am using msvisual c++ 6.0
thanks for the help

Hello, the codegurus around the world.
In fact, I don't understand the question very well, but.
1) Model dialog - use EndDialog() or call CDialog::OnOK() or OnCancel().
2) Modeless dialog - use DestoryWindow().
Humm. If you want to destroy the dialog called by the other application,
you need CWnd of this dialog........?
Have a nice day!

It is very easy to enumerate all open windows in order to get the CWnd of an open window.

I've posted this problem to the board yesterday, but I still don't know the solution.
Now I have a TouchScreen. When my finger touches the screen, a message will come out. I have to write a MFC program to access this message. For example, when the user touches the screen suddenly, the program will pop up a message box.
How can my MFC program checks this message and do the action suddenly and immediately?

> Now I have a TouchScreen. When my finger touches the screen, a message will come out.
Most Touch-Screens that I know of have drivers that make them simulate mouse movements with finger traces and clicks with finger taps.

If your Touch-Screen works as above, them your app can just lie in wait of a mouse message, and react to it. If not, what kind of drivers do you have for the Touch-Screen? A mouse-like driver? A driver that gives you grid/coord. information?
Peace!

Yeah.....I know I can make it as a "virtual" mouse message, but I don't want to do it in this way because there is indeed a "touchscreen" message. This message will give me coord. and touch or untouch or error touch message......
Thanks for your help.

If there IS a touchscreen message, you can catch it in PreTranslateMessage and deal with it accordingly.

i've gone over all the replies you've had for this issue and short of writing the code for you i don't see how you can get any more help from here ... please don't take this as a 'go away' type thing but read the answers you have been posted and you will see all the info you need to solve the problem i think
otherwise please state clearly what is wrong and what bits you don't understand so we can help to get this thing sorted

The reason you're having trouble getting an answer is because you aren't giving us enough information to actually help you.
Chances are, nobody here has used this product your using, or knows it's API. Since we don't know how the thing works, we don't know how to help you.

Hi all,
In a CListCtrl, is that the user can only select the ITEM ? Can the subitem in other column be selected individually too( only select the subitem )?? If can't, what should I use other than CListCtrl if I want to select cells horizontally ?
Please help! Thanks!
Vickie

u could either look around for an enhanced version of the clistctrl that allows individual cells to be selected / edited or you could (as i said before) use a grid control (there's a very cool one here on codeproject)

Yep.
> Can the subitem in other column be selected individually too( only select the subitem )??
Not normally, no. (At least, not that *I* know of.)
> If can't, what should I use other than CListCtrl if I want to select cells horizontally ?
There are various Grid and Grid-like controls out there that may give you this functionality. On a previous Brokerage-related project, I needed this same functionality. I ended up using the Custom Draw features of the ListView control to simulate it.
Using Custom Draw, you can highlight a specific column in the control. If you have some other way to keep track of the current "column selection", you can simulate column selection/highlighting.
Peace!

Does anyone know what these error messages mean? and how to fix this bug?
error LNK2001: unresolved external symbol "unsigned short __cdecl ABC_EventLk(unsigned long,unsigned long)" (?ABC_EventLk@@YAGKK@Z)
error LNK2001: unresolved external symbol "unsigned long hABC_Wnd" (?hABC_Wnd@@3KA)
fatal error LNK1120: 2 unresolved externals
************************************************************************************
I copy all related *.h and *.c files to my program's directory and add to my project list. However, still get the same messages

is ABC_EventLk your function? where does it come from?
