Ping function message box not working

Hi all, I am trying to use several different buttons to ping different ip's. So far only the first 3 buttons have ip's on them using their tags There is no error output message and it builds correctly, however, the Ping messagebox is not displaying. Please see attached code here: https://paste.mod.gg/nnjlefslfqhc/1

I don't see any instances of PingButton_Click in your xaml, so how are your buttons wired to your codebehind?

pauliologyOP•3w ago

Oh my apologies I changed all the names after pasting the code Still wasn't generating the popuo Popup

canton7•3w ago

Btw you can self-close tags if they have no content: <Button ..../> instead of <Button ...></Button> So, if the code you actually tried is different, update the code in your paste There aren't any click handlers in your XAML

@canton7 im looking at the latest bit of code you pasted in terms of how you would do it. I'm just wondering how would i apply the xaml. Does that take over my entire grid ?

canton7•3w ago

Yeah, the ItemsCollection dynamically generates buttons (using that DataTemplate), and lays them out using that WrapPanel That binding approach only really works if you're doing MVVM proper though -- it's painful if you're using the codebehind (but still do-able)

pauliologyOP•3w ago

data template being this ? PingButtons = new BindableCollection<PingButton>()

canton7•3w ago

No, the <DataTemplate>

pauliologyOP•3w ago

Yeah Would it be worth me converting my code to that now or not really ?

canton7•3w ago

Up to you

pauliologyOP•3w ago

Umm well i have say 9 pages with about 5-10 of those buttons on each page is that easier ?

canton7•3w ago

Depends how much you like copy-pasting 😄

pauliologyOP•3w ago

i don't mind if i knew exactly what i was doing 😄

canton7•3w ago

Time to learn!

pauliologyOP•3w ago

@canton7 could I ask you for a massive flavour favour well massive for me, maybe miniscule for you I am struggling to understand how you converted the functions and xaml earlier. This is my current latest version. It also has a function of which a button will pull an image from an ip address. I've used google as an example. However thats wrong because the ip address will be the same ip address of the device above it. For example DE camera, and DE snapshot will be the sameip whats the chances of helping me fix my code to utiilse your way and fix that function at the same time. because i believe that will help with both ping and image function

@canton7 did that explanation even make any sense

canton7•3w ago

Sorry, haven't had a chance to look

pauliologyOP•3w ago

all good, bud i know you are busy with your cuppa

pauliologyOP•3w ago

pauliologyOP•3w ago

this is a visual of what im talking about so imagine the top row would be devices that i would use the ping function for so there could be 5-10 of them the bottom row i am hoping to achieve, will open an image of the camera using the same ip from the top device in a popup window that i can close

canton7•3w ago

So each "item" is two buttons, one on top of the other?

pauliologyOP•3w ago

yes sir well under each other i have grid.row 0 = the ping function and grid.row 1 = the snapshot function

canton7•3w ago

I'd structure that as an ItemsCollection, with each item being that pair of buttons with some spacing between them It's annoyingly hard to data-bind to grids, useful as they are

pauliologyOP•3w ago

Could you help me out with that? I've really got no clue

canton7•3w ago

I'm afraid I've got a chunk of work to do this afternoon

pauliologyOP•3w ago

feel free to tell me to fuck off 😄 ok well in the interim, could you possibly just help correct my function slightly to save your time atm i have this

Image image = new Image();
var httpUrl = "https://www.google.com/images/branding/googlelogo/1x/googlelogo_light_color_272x92dp.png";

Image image = new Image();
var httpUrl = "https://www.google.com/images/branding/googlelogo/1x/googlelogo_light_color_272x92dp.png";

trying to get it to just take the ip from the Tag Property

canton7•3w ago

Trivially, you've got the sender right there

pauliologyOP•3w ago

I've got this although the image didn't load Xaml

<CustomControls:FancyButton Image="/Images/cameraIcon.png" Title="DE Snapshot" Grid.Column="0" Grid.Row="1" x:Name="LoadImageButton" Click="LoadImageButton_Click" Tag="https://www.google.com/images/branding/googlelogo/1x/googlelogo_light_color_272x92dp.png"></CustomControls:FancyButton>

}

no error message window pops up just blank

canton7•3w ago

What are you trying to do? Show a new window with the image in?

pauliologyOP•3w ago

yes sir so the window popped up correctly the image didn't load in it

canton7•3w ago

Google suggests you need to set StreamSource? It'll be something to do with creating the ImageSource Look in the Output window for clues

pauliologyOP•3w ago

ok last question for the night imagine this image

is kept behind a user/pass in the old days i could use http:// user:[email protected] to access image using my function i currently got, how do i implement that in c#

canton7•3w ago

That's a HttpClient thing Set the Authorization header to a new BasicAuthenticationHeaderValue or something IIRC? (assuming you're using basic authentication)

pauliologyOP•3w ago

its weird i can get it to pull the google image but when i try this link it errors failed to load image

pauliologyOP•3w ago

pauliologyOP•3w ago

whats the reasoning behindthat function hasn't changed at all

canton7•3w ago

No idea. Use Fiddler to see what it's requesting, and a hint at why it's failing

pauliologyOP•3w ago

will do its getting late for me, i have an early flight to the mines tomorrow 4am kinda why i was in a hurry to get it done, don't get to work on it while im away on the mines
