.net - Implementing INamingContainer Interface for UpdatePanel? -

-

Even in an attempt to find the answer to this problem, I have not received any clarification (not specifically discussing a GridWise How do I get the following error when I run a program with UpdatePanel? 

  Message: Control with ID be registered through 'lblDisplay' Applying RegisterAsyncPostBackControl or RegisterPostBackControl to INInContainer, IPostBackDataHandler, or IPostBackEventHandler Should rana.

UpdatePanel is: 

  & lt; Form id = "form1" runat = "server" & gt; & Lt; Asp: ScriptManager id = "ScriptManager1" runat = "server" EnablePageMethods = "true" & gt; & Lt; / Asp: ScriptManager & gt; & Lt; Asp: UpdatePanel id = "up1" UpdateMode = "Conditional" runat = "server" & gt; & Lt; Trigger & gt; & Lt; Asp: asyncPostBackTrigger ControlID = "lblDisplay" eventname = "load" /> & Lt; / Trigger & gt; & Lt; ContentTemplate & gt; & Lt; ASP: Heldfield ID = "hidden zone" run = "server" /> & Lt; Asp: HiddenField ID = "hiddenZone2" runat = "server" /> & Lt; Div style = 'width: 150px; Status: Absolute; Margin-left: 0; Text-line: center; '& Gt; & Lt; Span id = "clock" style = 'font-size: 125%;' & Gt; & Lt; / Span & gt; & Lt; Asp: label id = "lblDisplay" runat = "server" text = "" & gt; & Lt; / Asp: label & gt; & Lt; / Div & gt; & Lt; Div style = 'width: 150px; Status: Absolute; Margin-left: 150px; Text-line: center; Text-conversion: capitalization; ' & Gt; & Lt; Asp: label id = "lblDisplay2" runat = "server" text = "" interval = "5000" ontick = "tick" & gt; & Lt; / Asp: label & gt; & Lt; / Div & gt; & Lt; / ContentTemplate & gt; & Lt; / ASP: UpdatePanel & gt; & Lt; / Form & gt;

In my opinion, I have to implement the INInContainer interface for lblDisplay, but it's not sure how to complete it. Do I know the update panel information? Create a new object for ININGContainer?

The problem is that a postback does not fire the event - it is not interactive. To be registered as some postbacktriggers, it should burn the postback command in some way - usually in response to some user input - which can prevent UpdatePanel then or form of trigger Should have registered controls in which prevents incidents of fire - e.g. An INCContainer (for example).

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.

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...
