I'm using AvalonDock and I would serialize and deserialize my layout. But the callback (where I use the ContentId for create an instance of correct object) is not always called. For this reason the loaded not work correctly. I have tried to add one "try-catch", but not thrown exception.
This is my code:
` var layoutSerializer = new XmlLayoutSerializer(manager);
layoutSerializer.LayoutSerializationCallback += (s, e) =>
{
MyClass item;
if (items.TryGetValue(e.Model.ContentId, out item))
{
e.Content = item;
var tool = item as IMyClassToolApp;
var anchorable = e.Model as LayoutAnchorable;
var document = item as IMyClassDocumentApp;
var layoutDocument = e.Model as LayoutDocument;
if (tool != null && anchorable != null)
{
addToolCallback(tool);
tool.IsVisible = anchorable.IsVisible;
tool.IsSelected = e.Model.IsSelected;
return;
}
if (document != null && layoutDocument != null)
{
addDocumentCallback(document);
// Nasty hack to get around issue that occurs if documents are loaded from state,
// and more documents are opened programmatically.
layoutDocument.GetType().GetProperty("IsLastFocusedDocument").SetValue(layoutDocument, false, null);
document.IsVisible = true;
document.IsSelected = layoutDocument.IsSelected;
return;
}
}
e.Cancel = true;
};
try
{
layoutSerializer.Deserialize(stream);
}
catch
{
return false;
}`
Thank you for your help!
Are you sure your stream is O.K? If for example configuration file does not exist LayoutSerializationCallback method will not be called.
private void MainWindow_Loaded(object sender, RoutedEventArgs e)
{
try
{
MainWindow.logger.Debug("Entering: {0}", "MainWindow_Loaded");
string filePath = Path.Combine(
Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData),
#"Jofta\Analyzer\configs\AvalonDock.config");
if (!string.IsNullOrEmpty(filePath) && File.Exists(filePath))
{
XmlLayoutSerializer serializer = new XmlLayoutSerializer(this.dockingManager);
serializer.LayoutSerializationCallback += this.Serializer_LayoutSerializationCallback;
serializer.Deserialize(filePath);
}
MainWindow.logger.Debug("Exiting: {0}", "MainWindow_Loaded");
}
catch (Exception ex)
{
MainWindow.logger.Error("Exception in: {0}", "MainWindow_Loaded");
MainWindow.logger.Error("Message: {0}", ex.Message);
}
}
private void Serializer_LayoutSerializationCallback(object sender, LayoutSerializationCallbackEventArgs e)
{
try
{
MainWindow.logger.Debug("Entering: {0}", "serializer_LayoutSerializationCallback");
if (e.Model.ContentId == ObjectExplorerViewModel.AnchorableContentId)
{
e.Content = Workspace.Instance.ObjectExplorer;
return;
}
// ...
// ...
MainWindow.logger.Debug("Exiting: {0}", "serializer_LayoutSerializationCallback");
}
catch (Exception ex)
{
MainWindow.logger.Error("Exception in: {0}", "serializer_LayoutSerializationCallback");
MainWindow.logger.Error("Message: {0}", ex.Message);

i have a DisplayActionSheet that appears on Entry Focus. the thing is that after it appears and i choose an item, the DisplayActionSheet doesn't disappear it keeps popping up and i choose again and again and it keeps popping up. i don't understand why because it works well on both android and ios, but on UWP, it seems to be different. here is the code:
async private void edlevel_Focused(object sender, FocusEventArgs e)
{
urlClass urldata = new urlClass();
string uri = urldata.url + "/GetAllEdlevels/4";
try
{
HttpResponseMessage responsepost = await client.GetAsync(uri);
if (responsepost.IsSuccessStatusCode == true)
{
string outcome = await responsepost.Content.ReadAsStringAsync();
var result = JsonConvert.DeserializeObject<List<edlevels>>(outcome);
string[] edlevels_lst = new string[result.Count];
for (int i = 0; i < result.Count; i++)
{
edlevels_lst[i] = result[i].edlevel;
}
string action = await DisplayActionSheet("Education Levels", "OK", null, edlevels_lst);
if (action == "OK")
{
edlevel.Text = "";
}
else
{
edlevel.Text = action;
}
if(!string.IsNullOrEmpty(edlevel.Text))
{
if (edlevel.Text.Trim() == "Kgs" || edlevel.Text.Trim() == "Nursery")
{
discount.IsToggled = false;
discount.IsEnabled = false;
}
else
{
discount.IsEnabled = true;
}
}
}
else
{
await DisplayAlert("Operation Failed", "Response Failed!", "Cancel");
}
}
catch (System.Net.WebException exp)
{
bool ans = await DisplayAlert("Connection Failed", "Please Check Your Internet Connection!", "Retry", "Cancel");
if (ans == true)
edlevel_Focused(sender, e);
}
catch (Exception exp)
{
bool ans = await DisplayAlert("Connection Failed", "Lost Connection!", "Retry", "Cancel");
if (ans == true)
edlevel_Focused(sender, e);
}
}
what am i doing wrong?
Actually, you can use the label with adding a TapGesture. When you click the label twice you will triger the Tapped method.
<StackLayout>
<Label Text="tap GestureRecognizers">
<Label.GestureRecognizers>
<TapGestureRecognizer
Tapped="OnTapGestureRecognizerTapped"
NumberOfTapsRequired="2" />
</Label.GestureRecognizers>
</Label>
</StackLayout>
In the cs file:
void OnTapGestureRecognizerTapped(object sender, EventArgs args)
{
urlClass urldata = new urlClass();
string uri = urldata.url + "/GetAllEdlevels/4";
try
{
HttpResponseMessage responsepost = await client.GetAsync(uri);
if (responsepost.IsSuccessStatusCode == true)
{
string outcome = await responsepost.Content.ReadAsStringAsync();
var result = JsonConvert.DeserializeObject<List<edlevels>>(outcome);
string[] edlevels_lst = new string[result.Count];
for (int i = 0; i < result.Count; i++)
{
edlevels_lst[i] = result[i].edlevel;
}
string action = await DisplayActionSheet("Education Levels", "OK", null, edlevels_lst);
if (action == "OK")
{
edlevel.Text = "";
}
else
{
edlevel.Text = action;
}
if(!string.IsNullOrEmpty(edlevel.Text))
{
if (edlevel.Text.Trim() == "Kgs" || edlevel.Text.Trim() == "Nursery")
{
discount.IsToggled = false;
discount.IsEnabled = false;
}
else
{
discount.IsEnabled = true;
}
}
}
else
{
await DisplayAlert("Operation Failed", "Response Failed!", "Cancel");
}
}
catch (System.Net.WebException exp)
{
bool ans = await DisplayAlert("Connection Failed", "Please Check Your Internet Connection!", "Retry", "Cancel");
if (ans == true)
edlevel_Focused(sender, e);
}
catch (Exception exp)
{
bool ans = await DisplayAlert("Connection Failed", "Lost Connection!", "Retry", "Cancel");
if (ans == true)
edlevel_Focused(sender, e);
}
}
StackOverFlowExceprion raised, when logDirectory = new DirectoryInfo(m_logFileDirectory); line was executing. How can I solve the problem? Please help me.
This procedure writeLogToFile write a logMessge to File to logDirectory.

From the comments, this is what newLogFile looks like:
private void newLogFile()
{
try
{
Monitor.Enter(m_lock);
if (m_streamWriter != null)
{
endLogging();
m_streamWriter.Flush();
m_streamWriter.Close();
}
m_logFileNameSuffix = getLogFileNewSuffix();
m_streamWriter = File.AppendText(getLogFileName());
startLogging();
}
}

after downloading a JPG file from OneDrive successfully under Windows 8.1, I am not able to open it and use the stream as image source immediately. Instead, my app must run in a waiting loop to retry the opening until the exception "Error HRESULT E_FAIL has been returned from a call to a COM component" does not occur anymore. Or the app must inform the user to retry the action. After about one second or so, the file can be opened and the stream can be used as image source. This problem occurs if the JPG file was initially not available offline and my app downloads it. I want to know if anybody has a better solution for that problem. Here is some of my code:

I have tried again to open a "available online-only" file and as by a miracle the exception "Error HRESULT E_FAIL" did not occur any more. For what ever reason, I don't know. But, I really do not need to handle that scenario by myself. Thanks.
I have successfully integrated IMAPI2 using Interop.cs into my application. I can burn CD/DVDs without any problem. However, the event handler for MsftDiscFormat2Data update does not work, so I can't get my progress bar moving.
Here is the code I found at codeproject website:
private void backgroundBurnWorker_DoWork(object sender, DoWorkEventArgs e)
{
MsftDiscRecorder2 discRecorder = null;
MsftDiscFormat2Data discFormatData = null;
try
{
//
// Create and initialize the IDiscRecorder2 object
//
discRecorder = new MsftDiscRecorder2();
var burnData = (BurnData)e.Argument;
discRecorder.InitializeDiscRecorder(burnData.uniqueRecorderId);
//
// Create and initialize the IDiscFormat2Data
//
discFormatData = new MsftDiscFormat2Data
{
Recorder = discRecorder,
ClientName = ClientName,
ForceMediaToBeClosed = _closeMedia
};
//
// Set the verification level
//
var burnVerification = (IBurnVerification)discFormatData;
burnVerification.BurnVerificationLevel = _verificationLevel;
//
// Check if media is blank, (for RW media)
//
object[] multisessionInterfaces = null;
if (!discFormatData.MediaHeuristicallyBlank)
{
multisessionInterfaces = discFormatData.MultisessionInterfaces;
}
//
// Create the file system
//
IStream fileSystem;
if (!CreateMediaFileSystem(discRecorder, multisessionInterfaces, out fileSystem))
{
e.Result = -1;
return;
}
//
// add the Update event handler
//
discFormatData.Update += discFormatData_Update;
//
// Write the data here
//
try
{
discFormatData.Write(fileSystem);
e.Result = 0;
}
catch (COMException ex)
{
e.Result = ex.ErrorCode;
MessageBox.Show(ex.Message, "IDiscFormat2Data.Write failed",
MessageBoxButtons.OK, MessageBoxIcon.Stop);
}
finally
{

{

}
}
//

//

if (_ejectMedia)
{
discRecorder.EjectMedia();
}
}
catch (COMException exception)
{
//

//

e.Result = exception.ErrorCode;
}
finally
{

{
Marshal.ReleaseComObject(discFormatData);

Unfortunately, the update handler gets never called. I looked up everywhere on internet but could not find a solution. I saw some people with same problem but no one was able to answer.
The original code from Eric, http://www.codeproject.com/KB/miscctrl/imapi2.aspx?msg=2695517,
does work for some reason.
Can someone please help me?
I know, it's too late, but I've got the same problem with update callbacks.
Open Project->Properties->Application->Assembly Information and tick "Make Assembly COM-visible".
