Hi Robert,

By any chance, are you writing/rewriting a file that happens to be inside the “bin” folder?

Usually, the app will keep restarting whenever a file is either written or overwritten inside of the bin folder.

Best,

Alaa

Dear Julie,

Ok, Thank You

What version of Wisej are you using?
Can you provide a sample so that we can try to reproduce? You mentioned that you created a simple new Form from scratch with two controls to be shown at startup-can you zip that and attach that to this forum post?

Is this a deployment, or are you just running it from Visual Studio?

You can achieve this by editing the code of the NavigationBar component.
It is open source on GitHub, and can be found here: https://github.com/iceteagroup/wisej-extensions/tree/3.2/Wisej.Web.Ext.NavigationBar

Specifically, you’ll want to edit the file NavigationBar.Designer.cs (https://github.com/iceteagroup/wisej-extensions/blob/3.2/Wisej.Web.Ext.NavigationBar/NavigationBar.Designer.cs).

I’ve attached a sample that shows increased icon size, custom icon color, and custom icon color on hover. Run the sample and right-click on the button to open the context menu.

Here’s a code snippet from the theme file that shows where I edited the width/height of the icon, the color of the icon, and the hover color of the icon. You can find the full theme file in the sample-it’s called menucolor.theme.


"menu": {
"components": {
"item": {
"components": {
"icon": {
"states": {
"default": {
"properties": {
"width": 100,
"height": 100,
"marginRight": 8,
"scale": true,
"textColor": "#F16513"
},
"styles": {
}
},
"selected": {
"properties": {
"textColor": "#00FF57"
},
"styles": {
}
}
}
}
}
}


I’ve also included screenshots of what the theme looks like in the theme builder.

Note that you will have to edit the JSON text of the theme file manually to add the “width” and “height” properties to the icon- they are not included by default.

Here is the link to the documentation regarding the legend configuration. After trying a few different options, I am still unable to change the text color.

I’ve logged this as an enhancement request. We’ll consider adding it in a future release.

Hi Dino,

I will log an enhancement request for that feature and will be working on it.

Good proposal. This allow to not use complex hardware infrastructure (serial network converter) on application that need to manage serial device like legacy POS devices.

Can you provide a link to where you saw this in the ChartJS documentation? Does it include a code snippet showing how to do it in JavaScript?

If you know how to do it in JavaScript, you can simply run the JavaScript code from C#, like this:

Wisej.Web.Ext.ChartJS.ChartJS chartJS1 = new Wisej.Web.Ext.ChartJS.ChartJS();
chartJS1.Eval("JavaScript code goes here");

Another thing to note, for chartJS specifically, is that if you want to access the chart from inside chartJS1.Eval() you can use this.widget.chart

Here I used the Eval() function, which runs whatever JavaScript code you send it. You can also use the Call() function, which takes the name of a JavaScript function and runs that function.

Hello, how are you? Query in version 3.2, how do you change the gif of the startup loader?

Things to consider:

1.Could be caused by a lack of internet connection, or a firewall blocking Wisej attempting to validate the license.
See this forum response: https://wisej.com/support/question/invalid-server-license-upgrading-to-wisej-3-net-core

2.Double-check that there is a wisej-server.lic file in the root project folder. wisej-server.lic is automatically generated the first time the server activates a server license. You can also try deleting it, in case it’s out of date. If it’s deleted, a new one will be generated. https://docs.wisej.com/docs/getting-started-1/license-activation#server-license

3.What version of Wisej does your application use? The screenshot you provided shows a Wisej version of 3.1.10. The newest version of Wisej is currently 3.2.5.  If you are using a newer version of Wisej, perhaps it tried and failed to download the new license? https://docs.wisej.com/docs/getting-started-1/license-activation#server-license

4. Try deleting the old wisej-license.wx file. You’ll find 2 copies, one usually inside the application’s root directory (outside the bin folder) and one under C:\ProgramData\IceTeaGroup\Wisej. Delete the file and recycle the app pool, and see if that fixes the ‘Invalid Server License’ message.

5. Try rebooting the server and pasting the license into the web.config file. Make sure that you are using the Server Key and not the Developer Key.

6.Double-check that the key in the web.config file and the wisej-server.lic file match.

7.Enable tracing so that you can get the log file from the license manger- in case there are errors as it attempts to validate the license.

Hope this helps!

This appears to be a bug. We can replicate. Will let you know when we have a fix.

Hi again,

It looks like the deployment method makes the difference. It all works correctly if I publish the usual way with all the dlls included. And it does not if I publish as a single file (exe).
Have a look and see the difference in
https://win1-dev.mobics.gr/canvaswisejdll/ and

https://win1-dev.mobics.gr/canvaswisej/

It’s the same application deployed in the two different ways. just drag the mouse over tha canvas and then press the save to file button. In the second case you can see the missing widget error.

It looks like the Html2Canvas extension is missing from the single file deployment.

Regards,
Alex

Hi Carl,

glad you found the solution and thanks for sharing it in the forum.

Best regards
