binary - Extra bytes in .mid files -

-

I am trying to read information from a .mid file, but I see an extra byte that does not seem to be Is not part of any MIDI message I'm not sure how to predict / hand it with and it's throwing everything in my project any suggestions? Here are some examples:

4D 54 72 6 B 00 00 04 48 Track Header 00 Change the program 00 FF 03 07 54 72 61 63 6 B20 31 Title of track 00 B 05 00 Controller Event 00 64 00 00 06 00 00 00 00 00 B 20 20 Controller Event 00 FF 58 04 C 03 C 08 Time Signature 81 89 ???? 50 FF 51 03 F 42 40 Tempo 00 FF 2F00 End of Track 00 FF 21 01 00 Unknown Meta Event 30 B 9 00 00 Controller Event 00 07 64 01 A 32 01 5 B ???? 14 01 5d11 01 20 00 00 00 ???? Change 00 C Program 23 8 C7 C 90 23 ???

I suspect that I also have a breakdown because some of these are zero-zero delta times for no reason.

Every midi event has a delta time which is either 0 (this indicates that it happens at the same time as the previous event) or some positive value (it shows that after the last incident it must be) .

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

I am sending the content of an image in the body of the HTTP request (output stream) as a byte array, I want to read this stream of bytes in PHP scripts and take back an image.

Another option is to use and load the image.

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
