.net - PowerShell Runspace vs DLR -

-

Now with the available .NET 4.0 beta, and thus the broad availability of .NET dynamic language runtime, I think that Types of topics are going to be "hot"

I'm confused about the conceptual difference between DLR and PowerShell. I think if I want to provide scripting capabilities in my .net app, So I can enable scripting in DLR (and thus IRPathan or IronRB) , Or whatever Iron * languages ​​available for DLR), or a PowerShell host Runspace.

What are the pros and cons of each method? Why can I choose another? As a dynamic language, and a first-class .NET language on it, why does PowerShell not also target DLR?

You can consider "DLR v1.0" in DLR in .NET 4.0. This includes improvements to call site caching mechanisms, cross-language interop featuers, and existing LINQ expression trees. These are all features that are very useful for hosting languages, but are not hosting a single language.

And this is a missing piece in DLR 1.0 - a shared hosting story for all languages ​​but we start on as a hosting API, which we send on CodePlexXLL / DLR and IronPathon projects and O / IronBube is also given on gitb. Unfortunately we did not think we could drive these APIs to the quality of the ship for the net quality so that we do not include them. Especially we want to get more feedback from other languages ​​such as parvars and even VB and C # so that we can ensure that we have the right API.

Therefore, there is more or less the story of hosting this in every language, in which Iron Pethone and Iron Roubin are currently available. But we would love to see that they will be integrated in the future so that your users can choose which language to use. But there is nothing in the box to target the powerhield right now.

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...
