c# - Arc based gradient -

-

I am trying to make an arc (variable width, variable number of the degree - potentially a whole cycle), which goes slowly, says, red on one end for green on the other. I do not know how to specify a gradient on an arch to accomplish this.

For example, if you can imagine creating a round temperature gauge where the degrees from 0 to 500 different from the gauge marker on the circle. In the form of an added view, I gauge the perimeter of the grid To indicate the temperature, I would like a gradient color - being very hot (red) from good (green).

I have tried both a footprint brush and LinerarGradientBrush (but maybe I missed something).

Thank you.

This code goes from red to green (left to right) will create an arc Comes to the form. 

  Private Zero Button 1_Click (Object Sender, EventArgs E) {Usage (Graphics G = this.CreateGraphics ()) {LinearGradientBrush lgb = new LinearGradientBrush (New Point (0, 0), New Point (210, 0), color. Color, color green); Pen p = new pen (LGB, 10); G. Drawerk (P, 10, 10, 200, 200, -22.5 F, -135F); }}

This will work up to 180 degrees for the arcs. I have to think about doing this for a full circle.

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...

PHP - get image from byte array -

I am trying to create a back-end for my mobile application. 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. Can anyone tell me how can I do this? Thank you. You can obtain the request body $ body = Reading from file_get_contents ('php: // input'); What you do with that data Depending on you, you can write the data in a file as you mentioned that this is image data, you can drop the data into the object can do. 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...
