c# - The type of namespace name 'Control' could not be found (are you missing a using directive or assembly reference?) -

-

Using genetics, trying to set up an extension method in Net 3.0 and I get an error message, the above description on line:

(control control in parents.)

Do I have a director or assembly reference Am using

Thanks

What I'm trying to do is set this up (down) as an extender function: 

  Use the system Tax; Using System.Collections.Generic; Using System.Web; Using System.Web.UI; Namespace System.Rentime Compiler Services {Public Static Class Control Helper {Public Static T Search Control & Lt; T & gt; (This control manger, string control name) where T: has been found {T found = parent.Fund Controll (control name) as T; If (found! = Null) returns; Foreign Hair (Control Child. Control in Parents Control) {found = hair control. FIDC control (control name) as T; Break if (found! = Null); } Returns; }}}

I'm missing a reference to System.core.dll ... it drives me crazy!

Choose this for the technology you are using:

< Strong> Windows Forms:

This is located in System.Windows.Forms.dll in the System.Windows.Forms namespace.

WPF: (probably not this one, because there is no relevant control property in WPF squares)

This < Code> PresentationFramework.dll in System.Windows.Controls is located in namespaces.

Web Control:

It is located in System.Web.dll in the system. Web. UI Namespace.

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...

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...
