c# - Pass objects/vars between Page_PreInit and Page_Load -

-

I use the database to store page information and .NET (C #) I am creating pages from the form. Part of the process is to set the master-page (code-back) on the basis of what is in the database, and as I think, it has to be done in Page_PreInit .

My problem is how to pass objects and variables from Page_PreInit to Page_Load .

I am able to do it in this way, but I am using this method when doing random compiling errors: 

  The public partial category BuildPage: System .Web.UI.Page {protected static string pageData; Protected Zero Page_PreInit (Object Sender, EventArgs E) {--- SET pageData = Data from database, and set masterpages ---} Safe page page (Location sender, EventArgs e) To secure - For different purposes, I I'm not using Visual Studio to compile, just want to give a .NET compilation on the first page request on the flight. I have received two error messages:  
 1) "CS0102: 'buildpages' type already has a definition for 'pageddata'"  
 2) "ASPnet: Ensure Make sure that the square matches the 'legacy' attribute defined in this code file, and it extends to the right base class (such as page or user control). " 
 The odd thing is that sometimes the web page Requests on the server. And, for the time that it is not on the first request, when a random number of the page is refreshed, it will compile it completely. After compiling it all works fine until I do another change in the code behind it and it has to be compiled again.  
 I think that while getting those compilation errors, using that method,  Page_PreInit  and  Page_load . In other words, if I request data from the database twice, once in 'Page_PreInit' and 'Page_load' I never get those errors, but I really do not want to double the database load. 
 
 So my question really has two parts, first of all, that variables are an acceptable way of sharing or it is from  Page_PreInit  to  Page_load ? 
 
 And secondly, if this is an acceptable way, errors are unrelated and someone has seen errors that are just before repetitive web requests? 
 
 Thanks for any and all help! Fodder [/ b] 
 class. However, your member should  not   still .  Static  means that there is a single example in multiple threads. Every copy of that page, which is being executed for various requests reaching that page, is competing to read / write that member. 
 
 In addition to this, your class is marked "partial", that means another file can contain another square piece, which has additional members and methods for that  BuildPage  If the class declares you both the same  pageadata  member, they will fight.

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...
