Depending on where the image is and if you want to use an embedded image or a file:

To use a file:

control.ImageSource = “TrashCan.gif”;

control.ImageSource = “Images/TrashCan.gif”;

control.ImageSource = “http://server-somewhere.com/TrashCan.gif”;

To use resources instead use the Image property as in winforms:

control.Image = Resource.TrashCan;

etc.

Basically Image works exactly like in winforms. ImageSource takes a string which can be a name in the theme, a url, or a file name in the project.

Wisej always uses HTTP for data stores requests: datagridview, listview, fullcalendar, and possibly others. Data requests are done using a data store class that caches the pages and requests the visible range of data. Always uses http because: 1) http is deflated at the browser OS level, 2) with http the request is matched with the response, 3) its easier to debug in chrome. The most important reasons are 1 and 2.

Also images and postback handlers (like the canvas control) are handled through http requests. For example,  the websocket push part tells the canvas control that it needs a new set of canvas instructions, the control fires an ajax request to get the list of instructions and it gets a response with the data.

And the initial load is naturally done using http since you need http to upgrade to websocket and we use the initial request to return config data to the client.

I’ll ask the guys and girls at fecher to comment on load balancers they used with VWG and are not moving to Wisej. Our load balancing tests were done using Amazon ELB. Haven’t tried the new ALB.

One of the most mentioned open source load balancer seems to be HAProxy.

In general, the web server behind the load balancer should be unaware of the load balancer. All wisej needs to work properly is a load balancer that can route the same session back to the same server (they all do) and, if you want to use WebSocket, a load balancer that works with TCP instead of HTTP.

The additional optional load balancing feature that Wisej offer is the ability to return 503 under certain conditions using healthcheck.wx.

Hi Tim,

Sorry about the delay on this. The propertygrid is the bottleneck now. I’d say about 2 weeks out.

If the machine can access the internet (the activation is a simple http request on 80 to wisej.com) then it should work. However, the error

“NetworkInformationException”, Message: “Invalid access to memory location” indicates a possible problem with the network card or windows installation. I did a quick search and it seems like other people have the same problem. The problem is that “Invalid access to memory location” is an OS or .NET core bug unrelated to Wisej. It may be occurring when the license manager queries the network card. But it’s all kosher .NET classes.

You can try from another machine and copy the wisej-server.lic file.

This is fixed. We had 1.3.11 in dev builds shortly but now it’s 1.3.12 – there was still an issue with the design surface not being refreshed immediately.

Yes, it’s in the theme.

You can either create a custom theme, or add a mixin. Try this:

{
 "name": "MixinTheme",
 "appearances": {
   "nobuttons-spinner": {
     "inherit": "spinner",
     "components": {
       "upbutton": {
         "states": {
           "default": {
             "properties": {
               "visibility": "excluded"
             }
           }
         }
       },
       "downbutton": {
         "states": {
           "default": {
             "properties": {
               "visibility": "excluded"
             }
           }
          }
        }
      }
    }
  }
}

Now you can set the AppearanceKey property to “nobutton-spinner” to hide the buttons.

I don’t think that IE6 has any chance but I’m not sure. The minimum requirements depend on the theme and on the controls used. Qooxdoo was designed to work even with IE8, I think. However, wisej some controls use CSS3.

On the safe side, I ‘d say IE10 and the latest Chrome, Firefox, Safari and CSS3. You can add a custom expression to validate the browser in Default.json. See configuration in the docs.

The Wisej.Mobile framework will be different.
