On my current project I'm trying to include some sound. Now I have worked out how to use some of the MCI functions and messages to play my wav files.
Currently I have a looping background wav, and sevral other 'sound' wavs which are played depending on the users actions. (clicking a button etc..) Problem is, it sounds awful. Everything plays without a hitch, but the volume levels are just plain wrong. Most of my code is based on this tutorial http://www.codeproject.com/audio/mididemocp.asp with a few additions of my own.
Now my question is, how do you manipulate the volume levels of the files? My background music plays at the correct volume, but the other sounds are too quiet. Using the waveOutSetVolume() does not do what I need, it simply adjusts the windows global wave volume level. Also I must point out that I do not want to use DirectX or the MFC classes in this project.

Am trying to access a C++ win32 DLL (32bit) from an .exe project by dynamically loading the DLL as under;
Handle THandle;
errval Integer;
Handle=LoadLibrary("C:\\my folder\\testdll.dll");
if( Handle == NULL )
cout<<GetLastError()<<endl;;
I found that Handle is always set to 0, even if I try putting in the full path.
GetLastError is returning 182 which I believe is an Invalid Ordinal.
Anyone got any idea why LoadLibrary might be returning this error? It looks to
me as if there's something wrong with the DLL.
Also when I tried to load the DLL manually in the registry by typing the following under Start Menu->Run
regsvr32 C:\my folder\testdll.dll
Nothing happens, the command just gets back to the last window open.
Any ideas?

Try with some other DLLs to be sure.

I think you are correct! Try the obvious - right-click on the file and see if you can view its properties (version information from the resources), or try to open it up as resources using the debugger. Maybe try a tool like depends.
Trying to open the DLL proper in the debugger should help you determine if it is a valid Win32 executable.

Hello,
I am using VC++ & my application shows some wave-forms like sine wave & square wave. Here I want to show VC++ waveforms on the browser.
So which tool I need to integrate with my application?
How can I show my waveforms on the Browser?
If I click on Browser UI buttons, according to that wave from should take from my VC++ application & show it on the browser.
Thankx in adavnce,

It depends somewhat if you are using MFC or not.
I think you could make it an OCX.
Start with an ATL/Com project (if you need MFC, then check its checkbox), then insert a Full control into the project. It will give you a OnDraw() etc function in which you can draw the waveforms.
However this may not be the only way or the easiest.
this is this.

thanx,
I am using MFC , but how can I show same waveforms on the browser without ocx or ATL/COM?
is there HTML or Java applet supports? If supports then how to do it?

I am not so sure of other way(s).
About the html/applet support, I have never tried those. I hope someone else can help you with that.

How are you trying to catch the exception?
If you can catch the exception using a catch all (catch(...)), then you are likely not catching the MFC exception correctly.
Remember that MFC exceptions are caught by pointer, not by reference or value. And you must call Delete() off of the caught exception pointer if you do not re-throw it.

I want to execute an internal command in my program.
e.g. ren a.txt b.txt
winexec and ShellExecute do not execute internal commands.
system() executes it;
system("ren a.txt b.txt");
it wors fine; but shows consol window which i donot want to show.
Is there a way to execute the internal command without showing the consol window?
Thanks in advance ![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)

In addition to the above responses, you could also try: (I know WinExec is old but since it works still)
WinExec("cmd /c ren c:\\a.txt b.txt", SW_HIDE);
It is the /C switch which causes cmd.exe to terminate after executing the command. And the second parameter to WinExec: SW_HIDE causes the window not to be shown.
If the program should run on Win9X also, then make it command.com instead of cmd.exe.
this is this.
