In MetroDataWindow (Orchestra.Shell.MahApps v5.0.1)
protected virtual bool ValidateData()
{
var vm = _logic.ViewModel;
if (vm == null)
{
return false;
}
vm.Validate();
return vm.ValidationContext.HasErrors;
}
Does the last line reflect intended behavior?
return vm.ValidationContext.HasErrors;
I reached this while looking into why the OK button is disabled in the MetroDataWindow
You are absolutely right, but I think it's better to report bugs in the official issue tracker.

I need to know if night mode is activated, with a boolean or int, I found a boolean that detects but it only works from andorid R isnightmodeactive () and I can't find another way to know if night mode is activated or not, any idea
I did this test but I continue as before it does not throw anything, I do not know how to know what mode my device is in, night or day
public double isDark(int a) {
return a;
}
public void nightmode(){
AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_FOLLOW_SYSTEM);
if(AppCompatDelegate.getDefaultNightMode() == AppCompatDelegate.MODE_NIGHT_YES){
isDark(1);
}else if(AppCompatDelegate.getDefaultNightMode() == AppCompatDelegate.MODE_NIGHT_NO){
isDark(2);
}
}
Google it or search on developer.android.com. I found a similar question on StackOverflow.
Here is the kotlin code from that question
fun Context.isDarkThemeOn(): Boolean{
return resources.configuration.uiMode and
Configuration.UI_MODE_NIGHT_MASK == UI_MODE_NIGHT_YES
}
I am using Android camera2 to create a custom camera. The cameraDevice.close() method is slow and it makes UI freeze for 1 sec. I put it in another thread and it seems to work just fine. I want to know if this will cause some serious problem and whether there is another way to achieve this. Here is my closeCamera method:
private void closeCamera() {
boolean release = false;
try {
mCameraOpenCloseLock.acquire();
release = true;
} catch (InterruptedException e) {
release = false;
}
try {
preparing = true;
if (mCaptureSession != null) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && mCaptureSession.isReprocessable()
|| validCameraSession) {
mCaptureSession.close();
}
mCaptureSession = null;
validCameraSession = false;
}
} catch (IllegalStateException e) {
mCaptureSession = null;
} catch (Exception e) {
mCaptureSession = null;
}
try {
new Thread(new Runnable() {
#Override
public void run() {
if (mCameraDevice != null) {
if (openCamera) {
mCameraDevice.close();
mCameraDevice = null;
}
}
}
}).start();
} catch (IllegalStateException e) {
Log.e(TAG, "closeCamera: mCaptureSession - ", e);
} catch (Exception e) {
Log.e(TAG, "closeCamera: mCaptureSession - ", e);
}
if (release) {
if (mCameraOpenCloseLock != null) {
int lock = mCameraOpenCloseLock.availablePermits();
if (lock > 1) mCameraOpenCloseLock.release(lock - 1);
else if (lock == 0) mCameraOpenCloseLock.release();
}
}
}
I think it may cause crash when mCameraDevice has not been closed but user open camera again. But it is rare case, and I am thinking of putting another check before open camera again. I don't want my UI to freeze 1 sec for it to close, is there any other way I can achieve that except putting it in seperate thread?
As Alex Cohn mentions, the recommended practice is to do all camera-related work on a separate thread from the UI.
It also takes a long time to open the camera, or create a capture session, relatively speaking, so doing those operations not on the UI thread is also a good idea.
That said, as long as you're not losing track of your own app state (so that you don't try to use a camera device you've already closed by accident, for example), there's no reason you can't mix calls to the camera device or capture session from multiple threads. The classes themselves are thread-safe.
As far as I know, such freeze with cameraDevice.close() happens on some unfortunate devices, and sometimes is cured by performing a normal system upgrade.
But this is a little consolation if this happens to you, on your device. Actually, you are kind of lucky that you can prepare a fix for that. The end-users of your app will benefit from your misfortune.
Your code looks OK, if it delivers desired improvements for you. As I explained, it may be hard to reproduce this problem on another device.
I would rather put all closeCamera() logic on the same background thread. If you provided a Handler to openCamera(), as in the official example,
manager.openCamera(mCameraId, mStateCallback, mBackgroundHandler);
then I would suggest posting all closeCamera() sequence to this mBackgroundHandler.
My application works portait, ma i want fullscreen video playback even in landscape mode using the plugin mentionend above.
For this purpose I create a customrenderer to take access to native AVPlayerViewController Ios Control.
I tried in many many ways, but seems to be impossible to handle exit fullscreen event. In that method i want to force layout portrait. I have the code for reset orientation already implemented but the problem is to put the code in the right place.
Any other that faced the same issue??
I tried to search for something useful in AVPlayerView(not accessible), AVPlayerVideoController, AVPlayerCurrentItem etc
Any ideas?
Thanks you in advance.
I have translated the OC code to C# in this link for you, see the following codes:
using Foundation;
using CoreGraphics;
playerViewController = new AVPlayerViewController();
playerViewController.ContentOverlayView.AddObserver(this, new NSString("bounds"), NSKeyValueObservingOptions.New | NSKeyValueObservingOptions.Old , IntPtr.Zero);
public override void ObserveValue(NSString keyPath, NSObject ofObject, NSDictionary change, IntPtr context)
{
base.ObserveValue(keyPath, ofObject, change, context);
if(ofObject == playerViewController.ContentOverlayView)
{
if(keyPath == "bounds")
{
NSValue oldRect = change.ValueForKey(new NSString("NSKeyValueChangeOldKey")) as NSValue;
NSValue newRect = change.ValueForKey(new NSString("NSKeyValueChangeNewKey")) as NSValue;
CGRect oldBounds = oldRect.CGRectValue;
CGRect newBounds = newRect.CGRectValue;
bool wasFullscreen = CGRect.Equals(oldBounds, UIScreen.MainScreen.Bounds);
bool isFullscreen = CGRect.Equals(newBounds, UIScreen.MainScreen.Bounds);
if(isFullscreen && !wasFullscreen)
{
if(CGRect.Equals(oldBounds,new CGRect(0,0,newBounds.Size.Height, newBounds.Size.Width)))
{
Console.WriteLine("rotated fullscreen");
}
else
{
Console.WriteLine("entered fullscreen");
}
}
else if(!isFullscreen && wasFullscreen)
{
Console.WriteLine("exited fullscreen");
}
}
}
}
I'm using the MonoTouch SimpleMultilineEntryElement from the monotouch-element-pack (originally just MultilineEntryElement) and when I tap to insert somewhere in existing text, I can insert a single character and then the insertion point jumps to the end of the string. I've checked the sample application and the behaviour is the same so it appears to be something in the library rather than something I'm doing incorrectly. Has anyone else had this problem and resolved it?
In the SimpleMultilineEntryElement change the FetchValue to the following, basically what is happening is the current position in the text is being lost with each modification of the text taking you to the end of the text each time.
With the following code you are saving the current position in the text at the start and repositioning the cursor at the end.
public void FetchValue() {
if (entry == null) {
return;
}
int currentPos = entry.SelectedRange.Location;
var newValue = entry.Text;
if (newValue == Value) {
return;
}
Value = newValue;
if (Changed != null) {
Changed(this, EventArgs.Empty);
}
if (currentPos > 0) {
NSRange newPos = new NSRange(currentPos, 0);
entry.SelectedRange = newPos;
}
}
Not 100% sure if this is the issue, or if it can be an issue. But I thought entryKey and cellkey had to be unique to a specific element. Both are set to MultilineEntryElement and not SimpleMultilineEntryElement.
Was thinking if you previously have used a MultilineEntryElement it could be getting dequeued in GetCell.
var cell = tv.DequeueReusableCell (CellKey);

I have an url (e.g. http://localhost/Aanbod/Pagina.aspx) and I want to know the tab id, so I can make a friendly url with query (e.g. http://localhost/Aanbod/Pagina/QueryKey/QueryValue/).
Anyone has an idea?
Edit:
I'm not on the page itself. Want to know it from any page possible.
The url does not contain the tab id itself, so it can't be extracted.
if Pagina.aspx is a page in dotnet nuke like Home or Getting Started then you can find the tab id by
DotNetNuke.Entities.Tabs.TabController objTab = new DotNetNuke.Entities.Tabs.TabController();
DotNetNuke.Entities.Tabs.TabInfo objTabinfo = objTab.GetTabByName("Pagina", this.PortalId);
int Tabid = objTabinfo.TabID;
Well, this post is a little bit old, and I don't know if someone still looks for a solution. I had this problem recently and here is the pieces of code I wrote to solve it:
public int GetTabIDFromUrl(string url, int portalID)
{
int getTabIDFromUrl = 0;
// Try the "old" way with the TabID query string
if (url.ToLower().IndexOf("tabid") > 0)
{
Int32.TryParse(Regex.Match(url, "tabid[=/](\\d+)", RegexOptions.IgnoreCase).Groups[1].Value, out getTabIDFromUrl);
}
// When there is no result (because of advanced or human friendly or whatever Url provider)
if (getTabIDFromUrl == 0)
{
TabCollection tabs = TabController.Instance.GetTabsByPortal(portalID);
foreach (KeyValuePair<int, TabInfo> k in tabs)
{
TabInfo tab = k.Value;
if (tab.FullUrl.StartsWith(url))
{
getTabIDFromUrl = tab.TabID;
break;
}
}
}
return getTabIDFromUrl;
}
This could be a pain with sites that have a lot of pages, therefore it could be useful if you have some additional information to shrink the list that you have to loop through - e.g. a ModuleId of a module that is placed on this tab:
public int GetTabIDFromUrl(string url, int moduleID, int portalID)
{
int getTabIDFromUrl = 0;
// Try the "old" way with the TabID query string
if (url.ToLower().IndexOf("tabid") > 0)
{
Int32.TryParse(Regex.Match(url, "tabid[=/](\\d+)", RegexOptions.IgnoreCase).Groups[1].Value, out getTabIDFromUrl);
}
// When there is no result (because of advanced or human friendly or whatever Url provider)
if (getTabIDFromUrl == 0)
{
IList<ModuleInfo> modules = ModuleController.Instance.GetTabModulesByModule(moduleID);
foreach (ModuleInfo module in modules)
{
TabInfo tab = TabController.Instance.GetTab(module.TabID, portalID);
if (tab.FullUrl.StartsWith(url))
{
getTabIDFromUrl = tab.TabID;
break;
}
}
}
return getTabIDFromUrl;
}
Hope that helps someone...
Happy DNNing!
