-

Requirement: We have a bunch of images and without images, only to showcase products with front-facing pictures the wanted.

What did I do: I have tried almost all such resources:

And Their different combinations with luck. I think some things have changed in the new version of Magento. I am using version 1.8.1.0

Can anyone put some light here?

UPDATE: On my debugging, I found out that

- & gt; Adatitatophilter ('small_is'), array ('nob' => no_selection))

Actually worked but there is an error in the layered value filter I was thinking It is not working before. I am receiving this kind of error: ...

According to Roy's reply in response to the above question, I believe, we have to edit this file: Dana / Model / Layer / Filters / Price.php

Did you try it? 

  - & gt; Add AettyFolder ('small_is'), array ('nob' = & gt; 'no_selection'))

c# - .net WebSocket: CloseOutputAsync vs CloseAsync -

We have a working ASP.NET Web API REST service, which is one of the methods of our controller, HTTPTTEX. .) Socket handler code looks something like this ... Public async task socket handler (AspNetWebSocketContext context) {_webSocket = context.WebSocket; ... while (! Cts.IsCancellationRequested) {WebSocketReceiveResult Results = _webSocket.ReceiveAsync (Input Segment, cts.Token) .Result; WebSocketsStateCollusocketState = _webSocket.State; If (result.MessageType == WebSocketMessageType.Close || currentSocketState == WebSocketState.CloseReceived) {// What should I use.

c++ - How to properly scale qgroupbox title with stylesheet for high resolution display? -

-
I am trying to apply a stylesheet for QGroupBox (QT4.8), which works on the normal screen ( 96 dpi) high resolution screen (Yoga 2 Pro, 3200x1800, 275 dpi, windows 8.1). The following style looks good on the 275 dpi screen, but the top margins on a regular 96 dpi screen are far too big. QGroupBox {border: 1px solid red; Range radius: 7px; Margin-top: 12x; } QGroupBox :: Title {subcontrol-origin: margin; Subcontrol-position: left above; Padding-left: 10px; Padding-right: 10px; } Changing the top-margin has an effect, but I did not get a proper setting which works on both screens. If I shorten the value, the content of the group box overlaps with the title on 275 dpi screen. I was also playing with units "East", "PX", "MX", "PT". Reading the document I would have guessed, "2 X" was the correct solution, which should be scaled with different screen resolutions. Without the stylesheet, the groupbox works well on both screens. ...
