Does anybody know how to using Windows API, disable the sound for a single application only?
Thanks,
Nate

Can you more explain what programs?
|

It doesn't matter what program. Any program. I want to be able to disable all sound originating from any application of my choosing programmatically. I don't want to disable sound for all applications. I only want to selectively disable sound.

Do you have access to the code of said application? If not, then using Vista is the only solution that I'm aware of.
Another "possibility" would be to create some sort of monitoring application that simply monitored all created processes and if a process was created that should have no sound, act accordingly.

LRESULT OnTest(HWND hMetin, WPARAM wParam, LPARAM lParam)
{
hMetin = FindWindow(NULL, "metin");
Sleep(5000);
//Mouse move
SetCursorPos(100, 200);
Sleep(500);
mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, GetMessageExtraInfo());
Sleep(500);
mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, GetMessageExtraInfo());
Sleep(500);
//This code is Keybd source of send Message
SendMessage(hMetin, WM_CHAR, 'd', 0); Sleep(100);
SendMessage(hMetin, WM_KEYDOWN, 'd', 0); Sleep(100);
SendMessage(hMetin, WM_KEYUP, 'd', 0); Sleep(100);
SendMessage(hMetin, WM_KEYDOWN, 'd', 0); Sleep(100);
SendMessage(hMetin, WM_CHAR, 'd', 0); Sleep(100);
SendMessage(hMetin, WM_KEYUP, 'd', 0); Sleep(100);
return 0;
}

Thanks in advance

Maybe look into the SendInput Function[^] or the keybd_event Function[^].
I'm not sure how all those Sleep() calls effect your user interface. You're on your own there

I have an MFC app, developed on windows XP, that makes use of the alpha blending features of comctl32.dll version 6.0. I now need to make that app back compatible to Windows 2000, which only supports version 5.8.
Is there some way to install comctl32.dll version 6.0 onto Windows 2000? My app specifies the comctrl version through a manifest (see below), but as far as I can see Windows 2000 doesn't have a GAC.

Hello all
I have a C program that basically functions as a control loop for a DC motor. Right now, the program is two threads, one that forms a user interface where I can change parameters, and the other runs a loop to update the command to the motor. Parameters are stored in global variables accessable to both threads.
I would like now to make MATLAB able to modify these global variables or otherwise communicate with the control loop thread. Does anyone have an idea of how to open a communication channel like this? The first thing that came to my mind was just using a simple UDP socket, but I lack the proper toolbox to implement that.
Thanks in advance,
Greg

I think MATLAB has a good COM interface.

I have a Linker problem in VCPP600.
after migrating the Source code to a new directory, the linker insits in linking with nafxcwd.lib, as well as mfc42d.lib, which of course leads to conflicts. The Manifest Constant _AFXDLL is set, and have an #ifndef _AFXDLL/n #error 'Gotcha' implicidly or expilcitly in each file associated with the project. None of these fire!
the DSP File does not mention 'nafxcwd.dll' anywhere. Where do I go from here.

Hi,
I know that a constructer is not suppoused to return value, however what if my object is dependent on certin data and the constructer which lets say takes a string
as paramter finds that the data is in error is there anyway to tell this to the user of the object and maybe not create the object
Thankx

I think u can throw a exception in your constructor
|

If you throw an exception in the constructor the object will not be constructed and thus will not be usable.

Constructors do not return values, but can throw exceptions. (If constructors could give an error return value, by logical extension you would have to test every constructor, which would include declarations like 'int i=0')
The YACC concept would be that the effective return value of a costructor is the object it constructs. The constructor cannot return a 'Non'object, and proceed from there, it can only succeed or fail.
So, if the string data is in error, throw an exception.
An easier method is, to separate the Construction and Initialisation process, and write a method such as Init() which CAN return Value!

Why dont you go for parameterized constructor instead..
Use call by ref concept. Is this useful. Just pass one more argument in constructor as out parameter. retrun thru out parameter.
class CMyCls
{
public:
CMyCls(){}
CMyCls(CString str,int &nRet)
{
if(some thing1)
nRet = your value;
else if(some thing2)
nRet = your value;
else if(some thing2)
nRet = your value;
else
nRet = your value;
}
};
void main()
{
<big>int result = 0;</big>
class CMyCls obj("hello",<big>result</big>);
}
I dont know what you expecting. But hope this is useful 2 u.

if the result is not what I want then I dont really need the objext created
some have suggested a Throw/exception might do the trick

i want to create a hook which prevents file creation in my system... i want to prevent exe files being copied to my system. i thought i can do that by using the WM_GETMESSAGE in setwindowshookex... it works for keypress and other messages and if i know the messages for file system i can do what i thought... is it a different concept of handling the file system? hope i can get an answer from forum... if more information is needed from me i can post this again...

you can use api hook to hook "CreateFile" win32 api which I've invoked and find it's not stable,in IFS(Installable File System),you will use filter driver to get the creation flag and "filemon" source code will be your help.If you're interesting in such,please contract me in eraccn@gmail.com and I've got the "filemon" source code and some document about these.
