c# - Thumbnails asp.net -

-

I am trying to write an application that clicks a button to view images as thumbnails I have a Dalit in my model popup from a folder in a modal popup. But from there I do not know where to go I have already tried 4guysfromrolla solution, but it was not what I was looking for. How do I set images as thumbnails? I already have the following .... 

  string () = directory in the form of slow files. File files for each file in the form of gate files (server.mappath ("~ / folder1 / folder2 /"), "* .jpg") in the file as string. Shuttle (file. Last indexoff ("/") + 1, file. Length) 'Response Write (file & amp; & lt; br & gt; ") file = file & dim image = new image (as image) & image.ImageUrl = file image.ight = 50 Image.Width = 50 Me.Controls.Add (image) Next

Edit: New Question

I resize the images in JavaScript onmouseover . 

  image.Attributes.add ("

Is it possible to do this here? 

  & lt; ASP: data list id = "dl_thumbs" runat = "server">  Lt; img src = "& lt; % # Eval ("imageUrl")%> "height =" 50 "width =" 50 "heading =" & lt;% # Eval ("imageTitle")%> "Alt =" & lt;% # Eval ("imageAlt")%> />   Private Zero InitData (string folder) {var files = Directory.GetFiles (Server. MapPath (folder)); Var images = files.Select (i = & gt; new {imageUrl = folder} path. Gate filename (i), imageTitle = path. GetFileName (i), imageAlt = Path. GetFileName (i)}); Dl_thumbs.DataSource = Picture; Dl_thumbs.DataBind (); }

How do I save the image to a folder?

Thumbnails are usually processed and are customized versions of the original file.

The original file will be processed 500x500, then the thumb will be processed up to 50x50.

You must have 2 (or more images).

MyfavImageName.jpg

myfavImageName.thumb.jpg

or add another folder [thumb]

/ folder1 / folder2 / MyfavImageName.jpg

/ folder1 / folder2 / thumbs / MyfavImageName.jpg

You can also use the path to get the file name. Its low error prone: 

  file name = path. GetFileName (file);

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...
