sql server - Time query for sql database using Visual Basic -

-

I want to show maximum time and minimum time for a day in grid control by using Visual Basic from scale database. The table columns are: - 

  User ID, Username, Date, Time 1 Shakes 30/1/2009 10:11:22 1 Shakes 30/1/2009 10:15:22 1 Shakes 30 / 1/2009 12:15:22 1 Shakes 30/1/2009 13:15:22

Output must be in the grid 

  1 Shakes 30 / 1/2009 10:11:22 13:15:22

I go Here is something to believe in your table structure. 

  Make TableMbable (UserID Integer, Username varchar (20), [Date] Time of day, [time] varchar (8))

yours The time is stored as a varchar field because sql2005 does not have any time type, since it will display minimum and maximum time for each user and date. There are two options, if your time is HH: MM: SS then you can use the convert function. The second shows an example of parsing it and builds its own date. 

  Select UserID, User Name, [Date], Convert (varchar, MIN (convert (datetime, [time], 108), 108), Convert (Manor, Max (Date Time, [Time], 108)), 108) UserID, UserName, [Date] Select Date [Date] by URIID, UserId, Username, [date], Convert (varchar, MIN (DATEADD (Second, CAST) (Integer as SUBSTRING (time, 7, 2, AS), DATEADD (minutes, CAST (SUBSTRING (time, 4, 2, AS), DATEADD (hour, CAST SUBSTRING (time, 1, 2)) 0))), 108), convert (varchar, MAX (DATEADD ( Second, round (integer as SUBSTRING (time, 7, 2), DATEADD (minutes, cast (integer as time (4, 2), dateADD (hour, CAST (SBBTRI (time, 1, 2) as integer), 0))), 108) user id, username, [date] ORIDER BY user ID, [date]

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...
