I need to make a Virtual MIDI Port. ( actually several ) I have worked with MIDI just enough to be dangerous. I can trigger physical ports, but I need a way to create dummy ports to re-direct midi from one application to another.
There isn't a whole lot of information available that I've seen out there, but any direction or insight would be greatly appreciated.
Thanks

Do you need to code one, or just to use one?
The only one I know of that works with current Windows OS's is MidiYoke.. http://www.midiox.com/ [^]
As far as coding goes... no, don't know how that would be done.

thanks. i knew about midi yoke, but yes, i want to code my own.
i appreciate the time!

Hi,
I have a multi-threaded c++ application. I was wondering how I can calculate the memory footprint of my application and CPU % per thread from the program itself.
Please advise.

Search the message boards 
This subject has been addressed countless times...
I personally say...you can't (Win98 anyways) without a VxD, but on NT/XP systems I believe there are API functions you can call to retrieve this info...
I believe Win98 resource meter has a logging feature which might output what your looking for in a log file, you can then parse and display as required...
Cheers

I want to get a record from MyTable which GroupID=3 AND account='abc' AND usename='tom'" but it alway ERROR "Too few parameters"
<br />
CMyRecordSet is;<br />
str.Format("GroupID=%d AND account=\'%s\' AND usename=\'%s\'"<br />
,iGroupID<br />
,theApp.m_strAccount<br />
,theApp.m_strUsername);<br />
<br />
is.m_strFilter=str;<br />
is.Open();
Too few parameters. Expected 1. <= ERROR 
help me 
I think I do not do anything wrong in this SQL

is.Open(AFX_DB_USE_DEFAULT_TYPE,"SELECT * FROM MyTable WHERE GroupID=3 AND account='abc' AND usename='tom'");
both ERROR

Hello. Is it somehow possible to disable the linking between VK_RETURN and CDialog::OnOK? Whenever I press ENTER in my dialog, it calls the OnOK, and I would like to avoid this.. Is it possible?
|
|
|
|
|
1) Give the OK button another ID besides IDOK.
2) In the OnOK() handler, don't call the base class CDialog::OnOK().

I tried to override OnOK, and yes, the dialog doesn't close, but if I then add an OnKeyDown-handler to my dialog, it never receives any VK_RETURN-notifications.. Is this beacuse MFC "grabs" the VK_RETURN, and sends it to OnOK, or just beacuse I'm doing something wrong?
|

Depending on which control has focus, the dialog may not even "see" the key presses. Tell us more of what you are trying to do.

VK_RETURN actually invokes a default button in your dialog, which happens to be your OK button.
You could unchek "default button" property for it in the resource editor, or at a run time.

I have a block of data, say name, address, etc (could be 1000's of chars long) that wish to encrypt using a key and then decrypt using the same key. WHERE can I get some source. I checked out Codeproject, doesn't seem to have what I need.
Any help?
TIA

Hi !! I'm programming under Linux and compiling with GCC (C and C++ code). Where can I find manuals for all the functions and libraries that I can use ??
I've tried to use the gotoxy(int, int) function but there's not "conio.h" and if I include it, it begins to send error messages.
I need a manual (if its downloadable much better) where I can find all the functions and libraries.
Thanks in advance !!

Your Linux install should have all the documentation you could need. Look into the optional parts of the distribution.
In the area of what I assume 'gotoxy' (which is not any sort of standard C/C++) might mean try 'man curses'.

It was only an example, that function sets the cursor to the column and file wherever you want to go. But I would like to know how can I call the documentation about programming... I tried "man gcc" and it told me lots of things but there's anything about all the allowed functions and so on.
I'm programming under downloaded Linux Mandrake 10.0.
Thanks in advance !!

There is no guarantee that notepad.exe exists in any particular directory.
