c# - How to move the textbox caret to the right -

-

I would like to change all the characters entered in the text box in the upper case. Code will add character, but how can I get the correct direction? 

  Private Zero Text box3_keyPress (Object Sender, KeyPressEventArgs E) {textBox3.Text = = e.KeyChar.ToString (). ToUpper (); E.Handled = True; }    
 
 
  text box  to  above ; You do not need to manually process it. 
 
 Note that  textbox3.Text + = e.KeyChar.ToString (). ToUpper ();  The new character ends at the end of the string  even if the input is in the middle of the carat string  (which means that most users will be highly misleading). For this reason we can not assume that after inputting the character, the input carpet should appear at the end of the string. 
 
 If you still want to do this in the code, then you should do something like this: 
 
  // is required for backspace and for working in this way (Char.IsControl (e.KeyChar)) {return; } Int selStart = textbox3.SelectionStart; String = first text box 3 Lesson Shuttle (0, selStart); After the string = textbox3.Text.Substring (before.Length); TextBox3.Text = string.Concat (before, E.K.K. toString (.) ToUpper (), after); Textbox3.SelectionStart = before.Length + 1; E.Handled = True;

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...
