mysql - How to fix "Incorrect string value" errors? -

-

Looking at an application to abandon random email due to incorrect string value errors, I went though and used Several text columns have changed utf8 column charset and default column collate ( utf8_general_ci ) so that they can accept them. Most of the definitive errors, and non-Latin emails were stopped while stopping SQL errors.

Nevertheless, some emails still have irresis: (incorrect string value: column '' xx4 \ xC5 \ xCC \ xC9 \ xD3 \ xD8 'for column' content '' on line 1 with incorrect string value ... ')

Content column is a MEDIUMTEXT datatyb which is utf8 column charset and utf8_general_ci column Uses coated. There are no flags that I can toggle in this column.

Considering that I do not want to touch the application source code, unless it is necessary: ​​

  • What is the reason for that error? (Yes, I know that email is full of random garbage, but I think UTF 8 will be very approbatory)
  • How can I fix this?
  • Is this okay?

One thing I believed was that UTF was changing with variant of binary flag in varchar ([some large number]), but I am unfamiliar with MySQL, and I do not know if One such kind of thing is understandable.

"\ xE4 \ xC5 \ xCC \ xC9 \ xD3 \ XD8" Valid UTF-8 is not tested using Python: 

  gt; & Gt; "\ XE4 \ xC5 \ xCC \ xC9 \ xD3 \ xD8" .decode ("utf-8") ... Unicodecode error: 'utf8' can not decode a byte in codec position 0-2: invalid data

If you are exploring a way to avoid decoding errors within the database, then cp1252 encoding (aka "Windows-1252" aka "Windows Western European") is the most approved encoding - every byte Value is a valid code point.

Definitely this is not to understand the actual UTF-8, nor to other non-CP 1252 encoding, but it seems that you are not worried about it?

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...
