deployment - How to go about catching database and software version mismatch on deployed application? -

-

I am developing a standalone application that accesses a common database on a server. This will be used by some dozen people in my organization.

I know that I will need to update the software and database design. This creates the likelihood that someone will do a query on the database using the old software.

I already have a system that tries to start the old version of the user. application. However, this is not against anybody who keeps the application for a long time.

My idea was to keep a version entry (tblVersion or something) in the database and check it every time but not just read it.

In this way, I can catch things that (I think) may be that (I think) record (except tblVersion) is added to any table in DB , Is updated or removed even if the user has the latest version of SW: Check the version in DB about what the code contains, and if there is no mismatch, then add, update or delete the operation Do not allow. At the same time, I do not add tblVersion to DB overhead of many checks.

My question: Is this the sound? Is there a better way to go about it? If so, then?

Thank you!

A new, inconsistent rollout of a person's use case app is open and database schema ( Or interpretation) is modified in a structurally consistent, but meaningfully incompatible methods seem very narrow.

A schemine table with two and two toplevels, the second with the last schematic version of the existing schema version, is the second most catchy case, while not seriously describing its application.

Checking on each writing will be a terrible disturbance, if you are really worried about the scenario, then the timer stops every hour or two which checks the table version and pops up a dialogue Does a warning to the user to get a new version.

Once you complete a schema, you can bounce the DB to disconnect all existing sessions.

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...

Another option is to use and load the 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...
