How to change in windows phone the systemtray in portrait to show up and on landscape to hide?!
i have something like this now but it dont work:
void Pregled_OrientationChanged(object sender, OrientationChangedEventArgs e)
{
if (e.Orientation == PageOrientation.PortraitUp)
{
SystemTray.IsVisible = true;
}
else
{
SystemTray.IsVisible = false;
}
}
on the xaml page the shell:systemtray.isvisible="true" and it dont work. if i remove the visiblity from systemtray in xaml it is not shown at all.
i fixed it, it was an little bug in my code, i had to use PhoneApplicationPage_BeginLayoutChanged instead of Pregled_OrientationChanged i thought i can set the event handler name like i want... my mistake.
This code made it to work...
private void PhoneApplicationPage_BeginLayoutChanged (object sender, OrientationChangedEventArgs e)
{
if (e.Orientation == PageOrientation.PortraitUp)
{
SystemTray.IsVisible = true;
}
else
{
SystemTray.IsVisible = false;
}
}

I have a web application which is connected to SQL server management studio.
I have one problem to finish my application.
In my gridview users are able to edit their own reservation, but once i reach update part for the gridview it shows me that the users are able to edit the other reservation and here are some images to show you the meaning of this:
1) this the code in my gridview events
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
foreach (GridViewRow row in GridView1.Rows)
{
if ((row.Cells[9].Text.Trim()).Equals(HttpContext.Current.User.Identity.Name) == false)
{
//row.BackColor = Color.Red;
row.Cells[0].Controls.Clear();
}
}
}
protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
{
Label1.Text = "Changed";
GridViewRow selectedRow = GridView1.Rows[e.NewEditIndex];
foreach (GridViewRow row in GridView1.Rows)
{
int currentIndex = row.RowIndex;
if (currentIndex != e.NewEditIndex)
{
row.Visible = false;
}
}
}
}
2) this is to show you that user can edit only their own reservation
so how can i solve this ?
I have updated GridView's RowEditing event:
protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
{
GridView1.EditIndex = e.NewEditIndex;
// Bind Grid Again Here
}
My ultimate aim is to transfer a file from one Lync client to another. I have following code.
First of all I have following 2 events registered
1.
((Modality)_conversation.Modalities[ModalityTypes.ContentSharing]).ModalityStateChanged += Modality_ModalityStateChanged;
2.
((ContentSharingModality)_conversation.Modalities[ModalityTypes.ContentSharing]).ContentAdded += _sharingModality_ContentAdded;
code for those event is
void _sharingModality_ContentAdded(object sender, ContentCollectionChangedEventArgs e)
{
MessageBox.Show("content added\n"+e.Item);
}
void Modality_ModalityStateChanged(object sender, ModalityStateChangedEventArgs e)
{
if (e.NewState == ModalityState.Connected)
{
textBox1.Text += "\nconnected";
send_file();
}
if (e.NewState == ModalityState.Connecting)
{
textBox1.Text += "\nconnecting";
}
}
Then I have a method which creates a file in isolated storage named "abc.txt".
Next there is a code which connects the content sharing modality.
private void button4_Click(object sender, RoutedEventArgs e)
{
if (_conversation.State == ConversationState.Active)
{
((Modality)_conversation.Modalities[ModalityTypes.ContentSharing])
.BeginConnect((ar) =>{((Modality)_conversation.Modalities[ModalityTypes.ContentSharing]).EndConnect(ar); }
, null);
else { MessageBox.Show("conversation not active"); }
}
After this there is 'send_file' method which actually upload the file. (this method id previously called when modality state changes to 'connected' but there (I think) conversation changes to multiparty and method returns false at 'canInvoke' statement. So Im calling it again and this time it succeeds. It is as below
void send_file()
{
if (((ContentSharingModality)_conversation.Modalities[ModalityTypes.ContentSharing]).State == ModalityState.Connected)
{
try
{
if (((ContentSharingModality)_conversation.Modalities[ModalityTypes.ContentSharing]).CanInvoke(ModalityAction.CreateShareableNativeFileOnlyContent))
{
ContentSharingModality contentSharingModality = (ContentSharingModality)_conversation.Modalities[ModalityTypes.ContentSharing];
contentSharingModality.BeginCreateContentFromFile(ShareableContentType.NativeFile, "samplefile.txt", fileNameFromIsolatedStorage, true,
(ar) =>
{
ShareableContent sContent = contentSharingModality.EndCreateContentFromFile(ar);
//_NativeFileNameAndPath = string.Empty;
sContent.Upload();
}
, null);
MessageBox.Show("upload done");
}
else { MessageBox.Show("u cannot invoke"); }
}
catch (Exception e1) { MessageBox.Show(e1.Message); }
}
else { MessageBox.Show("modality inactive"); }
}
Finally this is all I'm trying to do. The same code will lie on both sender & receiver machines. I'm new to lync development and very confused about what is going wrong. Please help. Thanks!
I have a code which show privacy policy URL in charm settings bar.But what I need is like when user clicks on the privacy policy link it should open another page in charm settings with a back button.How to do the same in the below code
private async void OpenPrivacyPolicy(IUICommand command)
{
Uri uri = new Uri("https://sites.google.com/site/mysite/");
await Windows.System.Launcher.LaunchUriAsync(uri);
}
Finally I figured out the solution,thanks to windows 8.1 Appsetting sample app . First of all add a settingsFlyout XAML page to your project.I added the privacy flyout code in my app's home page like this
protected override void OnNavigatedTo(NavigationEventArgs e)
{
SettingsPane.GetForCurrentView().CommandsRequested += onCommandsRequested;
}
protected override void OnNavigatedFrom(NavigationEventArgs e)
{
SettingsPane.GetForCurrentView().CommandsRequested -= onCommandsRequested;
}
void onCommandsRequested(SettingsPane settingsPane, SettingsPaneCommandsRequestedEventArgs e)
{
SettingsCommand defaultsCommand = new SettingsCommand("Privacy", "Privacy",
(handler) =>
{
Privacy sf = new Privacy();
sf.Show();
});
e.Request.ApplicationCommands.Add(defaultsCommand);
}
then in my Privacy.xaml page I added the following code
public Privacy()
{
this.InitializeComponent();
this.Loaded += (sender, e) =>
{
Window.Current.CoreWindow.Dispatcher.AcceleratorKeyActivated += SettingsFlyout1_AcceleratorKeyActivated;
};
this.Unloaded += (sender, e) =>
{
Window.Current.CoreWindow.Dispatcher.AcceleratorKeyActivated -= SettingsFlyout1_AcceleratorKeyActivated;
};
}
void SettingsFlyout1_AcceleratorKeyActivated(CoreDispatcher sender, AcceleratorKeyEventArgs args)
{
// Only investigate further when Left is pressed
if (args.EventType == CoreAcceleratorKeyEventType.SystemKeyDown &&
args.VirtualKey == VirtualKey.Left)
{
var coreWindow = Window.Current.CoreWindow;
var downState = CoreVirtualKeyStates.Down;
bool menuKey = (coreWindow.GetKeyState(VirtualKey.Menu) & downState) == downState;
bool controlKey = (coreWindow.GetKeyState(VirtualKey.Control) & downState) == downState;
bool shiftKey = (coreWindow.GetKeyState(VirtualKey.Shift) & downState) == downState;
if (menuKey && !controlKey && !shiftKey)
{
args.Handled = true;
this.Hide();
}
}
}
Thanks for all the help everyone! And this code works!If anyone facing difficulty just hit me ;)
// Get the camera
private void getCamera() {
if (camera == null) {
try {
camera = Camera.open();
params = camera.getParameters();
} catch (RuntimeException e) {
Log.e("Camera Error. Failed to Open. Error: ", e.getMessage());
}
}
}
// Turning On flash
private void turnOnFlash() {
if (!isFlashOn) {
if (camera == null || params == null) {
return;
}
// play sound
playSound();
params = camera.getParameters();
params.setFlashMode(Parameters.FLASH_MODE_TORCH);
camera.setParameters(params);
camera.startPreview();
isFlashOn = true;
// changing button/switch image
toggleButtonImage();
}
}
My code that gets involved with flash on is above, any suggestions,how to make the flash not open the moment my app opens but only when i press the button
I would guess you are calling turnFlashOn() in onCreate() and don't have a button ClickListener. But it is possible you could be calling turnFlashOn() in onStart() or onResume().
To have it turn on with a button press you should do something like
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.your_view);
flashlight_button = (Button) findViewById(R.id.your_button);
flashlight_button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
getCamera();
turnOnFlash();
}
});
}
I built an open source flashlight for Android that you can check out at Flashlight by Joe github.
I have a slider in my windows phone 7.1 project. When manipulated, this slider fires an event which starts a background worker to performs several trigonometric operations.
If I move the cursor on the slider, I have a certain delay in the response although I have implement background worker cancelAsync method in manipulationstarted event, I would like more responsiveness, how can I achieve this?
Code:
private void sliderCosinus_ManipulationStarted(object sender,ManipulationStartedEventArgs e)
{
if (bw.WorkerSupportsCancellation == true)
{
bw.CancelAsync(); // Cancel the asynchronous operation.
}
}
private void sldCosinus_ManipulationCompleted(object sender, ManipulationCompletedEventArgs e)
{
try
{
Value = Convert.ToInt32(sldCosinus.Value) * 10;
}
catch
{
// errore message here
}
finally
{
}
}
private void bw_DoWork(object sender, DoWorkEventArgs e)
{
BackgroundWorker worker = sender as BackgroundWorker;
if ((worker.CancellationPending == true))
{
e.Cancel = true;
}
else
{
Dispatcher.BeginInvoke(() => app.IsEffectApplied=TrigonometricTrans()
// TrigonomtriecTrans calculate sin and cosinus for every pixel in image
}
}
private void bw_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
// progress bar here
}
private void bw_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
if ((e.Cancelled == true))
{
//this.tbProgress.Text = "Canceled!";
}
else if (!(e.Error == null))
{
//this.tbProgress.Text = ("Error: " + e.Error.Message);
}
else
{
DoubleBufferToScreen();
}
}
