Can I update a reaction navigation tab when I access it?

Is it possible to update a reaction navigation tab when I access it?

For example I have 2 tabs "Home" and "Settings" …

If on the Home tab I navigation.navigator (& # 39; Settings & # 39;)the leader goes to settingsHowever, if the settings were previously rendered, playback will not be repeated.

can I activate it automatically when I access the settings and force the tab to render? (Update status, etc …)

Unauthorized reset of the Samsung Galaxy Tab A

Someone reset my brother's Samsung Galaxy Tab A and we don't know how to access it because our email addresses are not recognized. He lives in a dormitory for people with disabilities and we tried to ask but nobody knows anything. Is there any way we can get it working again? We don't care about the data because he only uses it to play simple games.

Galaxy Tab S5E and multiple SD cards

I received a Galaxy Tab S5E today as an image editing program. This is the 64 GB version, so I took a micro SD card and inserted it. A 128 GB card. The card and tablet work together as expected.

I also got a USB-C card reader to insert my camera's SD cards on the go.

I have the problem that the USB card reader only works when I remove the micro SD card and vice versa.

Is there any way to fix this?

The card reader does not register as an SD card. It is registered as a "USB mass storage device", so I am not sure why there should be conflicts.

swift – How do I change this segment to switch to any view controller and not a tab controller?

I need to change this segment from a segment to a tab controller to a segment to a view controller that is not part of the tab.

Extension ScanViewController: AVCaptureMetadataOutputObjectsDelegate {

    func metadataOutput(_ output: AVCaptureMetadataOutput, didOutput metadataObjects: (AVMetadataObject), from connection: AVCaptureConnection) {
        // Check if the metadataObjects array is not nil and it contains at least one object.
        if metadataObjects.count == 0 {
           //"No QR code is detected"

        // Get the metadata object.
        let metadataObj = metadataObjects(0) as! AVMetadataMachineReadableCodeObject

        if supportedCodeTypes.contains(metadataObj.type) {
            // If the found metadata is equal to the QR code metadata (or barcode) then update the status label's text and set the bounds
            if metadataObj.stringValue != nil {
                print("from Scan (metadataObj.stringValue!)")
                let nvc = self.tabBarController?.viewControllers?(1) as! UINavigationController
                let vc = nvc.topViewController as! SearchViewController
                vc.keyword = metadataObj.stringValue!
                vc.scope = 1
                vc.isAutoSearch = true
                self.tabBarController?.selectedIndex = 1



How can I find out which tab or which website (in Google Chrome) uses a lot of memory?

Sometimes a website in Google Chrome may consume a lot of memory after a day or two (and the hard disk space objected to by MacBook is running low).

It could be a mistake if I close a certain tab and wait 2-3 minutes, then the hard drive suddenly recovers 2 GB.

Is there any way to find out which website uses so much storage space other than errors and mistakes?

(Some web pages don't appear to be harmful, but they could be analytics or the ad system where the code has a lot of memory leaks.)

javascript – event after loading context / ribbon tab commands?

In MS Project Server, on the Project Center page, I want to specify that linked sub-projects are automatically displayed in the main view.

You can view the sub-projects by clicking the button PROJECTS Tab in the ribbon and check the box to show / hide sub-projects.

This setting appears to be retained across sessions (possibly stored in a cookie?), But is "personal" for each user and I want sub-projects to be visible to every user without having to go to the ribbon and check the box.

I know you can run ribbon commands

SP.Ribbon.PageManager.get_instance().get_commandDispatcher().executeCommand('CommandName', propertyBag);

and I even found the right command from the Project Server ribbon to show / hide the sub-projects. So that this command can be available you have to call the distribution list _ribbonStartInit with the … correct namespace? … not sure what it's called exactly, but it looks like a namespace.

In any case, the following works in a script editor web part on the Project Center page:

SP.SOD.executeOrDelayUntilScriptLoaded(function() {
     _ribbonStartInit('Ribbon.ContextualTabs.ProjectCenter.Home',true, event);
    setTimeout(function() {
        SP.Ribbon.PageManager.get_instance().get_commandDispatcher().executeCommand('InsertedProject', {On:true});
    }, 100);

However, I'm not particularly happy that I have to use it setTimeout a delay between that _ribbonStartInit and executing the ribbon command. But you to do need a delay – this:

SP.SOD.executeOrDelayUntilScriptLoaded(function() {
    _ribbonStartInit('Ribbon.ContextualTabs.ProjectCenter.Home',true, event);
    SP.Ribbon.PageManager.get_instance().get_commandDispatcher().executeCommand('InsertedProject', {On:true});

doesn't work there 'InsertedProject' Command is not available until it is loaded, which (apparently) is out of sync.

So my question is, is there an event I can hook into that tells me when that Ribbon.ContextualTabs.ProjectCenter.Home Commands have been loaded and are available so I don't have to rely on them setTimeout?

I have found that there is one SP.Ribbon.PageManager.get_instance().add_ribbonInited() Function that seems to allow adding a callback that runs after the ribbon has been "initialized", but I tried and the call does not seem to work

_ribbonStartInit('Ribbon.ContextualTabs.ProjectCenter.Home',true, event)

which, TBH, I have just taken from the inspection what happens when you click on that PROJECTS tab, so I'm not even 100% sure what that is event is part of it. I assume that it is the triggering event (i.e. the click on the tab) and no callback function.

Authentication – SPFx WebPart on the Microsoft Teams tab AAD token error

I have a Microsoft Team application, which is an SPFx web part that is installed on the underlying SharePoint site. The app has appeared on a tab.

I have not been able to authenticate with an AAD token in the past few days. This worked for most of 2019, but for some reason the following error is now being displayed in the console:

Enter image description here

When I go to the Network tab, I see the following:

Authorize the 4? Endpoints seem fine, but when it tries to call them
I can see in the response headings that they are returning:

Enter image description here

Which in my opinion prevents authentication via AadHttpClient from being successful.

Does anyone know how I can get the Tenant x Frame options to enable embedding in our Microsoft team? (This also worked well in the past)
