I have programed a application which has a on screen keyboard which plays all the piano notes when the button is pressed but i was wondering is there a way of making the keyboard sound different musical instruments when the keys are pressed? I have used hexadecimal values for the normal piano keys.
Any suggestions would be welcome.

You need to send a program (or patch) change for the channel to select a new instrument. GM says that a piano is program#1, for example.

Any Ideas on how to go about doing it? Or where best to look.

Well, presumably, you're sending NOTE ON/NOTE OFF messages at the moment.
1001nnnn 0kkkkkkk Note On event.
0vvvvvvv
1000nnnn 0kkkkkkk Note Off event.
0vvvvvvv
where nnnn is 0-15, being the MIDI channel number.
You should be able to change to a different patch by sending
1100nnnn 0ppppppp
ppppppp is your patch number, less one; where 1 = Acoustic Piano, 15 is Tubular Bells, 22 is Accordion.
Check out this[^]for a list of patches, assuming your MIDI target device is GM compatible.
You don't say how you're sending the messages;
If you're using midiOutShortMsg, then you need something like:
0x0000CnPP as the data to send, where n is your channel, and PP is your patch (0..126 or 0-7E in hex)
Hope that helps.

I want to manage user accouts on an active directory(2000 server) through Internet.How can I do it with VC 6?
|
|
|
|
|
why using VC 6?
use the management console!
Don't try it, just do it! 
|
|
|
|
|
because I want to make a program for someone who don't know much about it,and the program would have friendly interface and be easy to operate remotely.Unfortunately I know little about the interface of active directory.So I need some help.

Hi.
I have started a MDI project. I have a view derived from CFormView.
In that form there are a few textbox and buttons. I want to call another view, (derived from CFormView), when the user press a button.
In fact, there is a button "Next" and a button "Previous", when the user press "Next" I want to show other form, and so on.
How can I do that?.
How can I managed multiples views, (derived from CFormView, CScrollView, etc), so I can show it, (or hide it), from differents events?.
In all these views the user fills some fields to finally update or query a SQL Database, but I dont have problems with that.
Thank you and regards from Argentina.
Demian.

I've been trying for ages now to design a simple chat client based on dialogs and Csocket with MFC, which allows clients to send simple text messages to a server. I've read most of the articles here, but no matter what, i still cant seem to get my program to run. I've examined the chatter and chatsrvr examples that come with visual studio, but when i try to design my program along those basics, it still doesnt run/build. can anyone help me out?
|
|
|
|
|
what help do you really expect to ?
about MFC or sockets...??
doing a chat client is not very difficult (even if it can become if you want to apply correctly the IRC protocol...
i wait for your response to give you (or to try to) more details.

i'm sorry, i shouldve replied... i need help mostly with the sockets, and u read my mind, i would actually like to follow up with applying the IRC protocol ... any help/sample code with documentation/comments with mostly the simple chat part that u can give would be GREATLY appreciated... thanks for even replying so far
|

|

for the protocol, search on the net for the RFC1459.
I found a good page about this, but.... in french  fortunately, i'm french so i don't have translation problem, but i aggree, that will be hard (very hard) for you ! lol
anyway, you can have a look if you want at this :
http://www.csadmin.net/rfc1459.php
About sockets, i don't knom myself about CSocket, but but you can also have a look at "Beej's Guide to Network Programming", Originally made for Unix/Linux socket programming. Csocket and Linux Sockets are not so far... that can be very interresting to read it (PDF format), but i've lost the address. you'll have to search for it once again

I already have links to the rfc, its programming with the CSocket class that i need the help with...

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vccore98/HTML/_core_windows_sockets.3a_.sequence_of_operations.asp
if u didnt go through this site then please try.It will give you better idea about sockets

Thanks alot for the link, but i've done most of my research at MSN. However, i am very happy to say that on further trial&error, i've managed to get the code working... thanks so much for the help thateveryone has given.

Hello at all,
imagine the following situation:
You have created an auto-signaled event, and multiple Threads are waiting for this event to get signaled. The event in addition gets signaled, and one thread starts its execution which implied the event has gotton nonsignaled. So my question is, when does the event gets again signaled ?
Thanks in advance!
|
|
|
|
|
What made it get signalled originally?
If some process/thread is running and periodically signalling, then presumably it can signal again. If not, something has to happen to kick-start. Would the thread that was started not signal the thread prior to waiting on the event?

Greetings...
In VC++ 6 I want to create an activeX that contains another activeX, is this possible?
I have tried subclassing the control but I cant get the thing running?
It works if you subclass from ActiveX's that are listed in the project wizard dropdown (upon wizard project creation, step 2 I think, like BUTTON for example) but does not if you are trying to inherit from a custom activeX!!!
Cheers

Hi Guys,
I have run into a problem for which I havent found a solution till now.Iam trying to show it here in a perspective in which Iam doing it:
I want to draw a bitmap to the screen
m_deviceContext-is the deviceContext to Which I want to draw my Bitmap.
Its mapping mode is set as MM_TWips.
CDC dcMemory;
dcMemory.CreateCompatibleDC(m_deviceContext);
CBitmap *bitmap=CBitmap::FromHandle(handle);//Handle of BitMap is passed here.
BITMAP bm;
bitmap->GetBitmap(&bm);
CBitmap* pOldBitmap = dcMemory.SelectObject(bitmap);
I draw it as follows:
xCord,-yCord,srBpWidth),srBpHeight are in Logical units.
m_deviceContext->StretchBlt(xCord,-yCord,(srBpWidth),(srBpHeight),&dcMemory,0,0 ,bm.bmWidth,bm.bmHeight,SRCCOPY);
(Figure Attached)
I get the figure but it is drawn from the co-ordinate point "up"(As a mirror Image ).I want it to drawn "Down" from the co-ordinate point or Is there any way to inverse it....
Thanks....

hello, i'm doing a project using mfc, vc++... i'd created a dialog as my first window, i decided to create a menu as my second window, however, to link the menu to the dialog is not as easy as what i think...
if i wanna call a second dialog using the first dialong, i may use the .domodal to call it... but if i wanna call a menu, what should i do with it???
help!!!

I guess it's CMenu::TrackPopupMenu you're looking for, probably with TPM_RETURNCMD flag.
