php - Connect multiple tables in different databases? MySql -

-

Hey, I have a good way of using at least 2 database php in mysql and collecting information within each Looking to connect to the tables they database from

The tables will be related information such as I have site names in a database ('SiteInfo') in a table called 'database'. I also have a site description in another database ('sitedescriptions') in a table named 'Description'.

I can not get these two databases to talk to each other. Does anyone know how I can go about doing the above work? I am very new to php / mysql.

In addition, there are three lines of information related to a site in the table of the site in the 'Description' table

Thanks for any help.

A good strategy for you may be to define a single MySQL user, whose database Have similar access to something like this: 

  Allow everyone on sitino * 'Password' identified on user @ localhost; To authorize the 'password' user @ local host; Flush Pvt .;

Once you have a connection that is established as a user, then you will have access to both databases, and they are easily referenced by putting their table names with the database name can do. 

  SELECT * from siteinfo.sites;

If you can not join your tables in the database with any difficulty in this way, to answer your second question, to get all three description lines for a site, then You can do this (assuming the sites have the same ID in each database, or the same name, or something unique that you can join on): 

  select * siteinfo. Join the site d as Left sitedescriptions.description as s.siteId = ds IteId ou s.siteId = 123;

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...
