Try it: That's what GetExecutingAssembly does - returns the DLL if the code is in a DLL, and the EXE if it's still in the original app assembly.
There is another methods to get the EXE directly: Assembly.GetEntryAssembly[^]

You can see my approach in response above to Richard, any comments?
var versInfo = FileVersionInfo.GetVersionInfo(dllPath);
return String.Format("{0}.{1}.{2}.{3}", versInfo.FileMajorPart, versInfo.FileMinorPart, versInfo.FileBuildPart, versInfo.FilePrivatePart);

There is File version info and Assembly version info. The two are not the same.
The question is which one are you really looking for.

The one I am looking for is which is used in C++ code I showed

If it's freezing the UI, then it's probably because the file wipe is taking a considerable amount of time - and because it's all being done in the same thread, the UI can't update until the long running task is complete.
Move your Wipe into a different thread and it should "unfreeze" the UI. Have a look at the BackgroundWorker class[^] - it's easy to use and provides event for progress reportign and task completion.
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

1. You need to call StartWipeFile() on a different thread.
2. When posting, check that you don't mis-paste the code - such as showing & quot; etc.
3. Do a little debugging yourself - just clicking the "Break into debug" would have shown you the problem

Hello All exoperts,

If you got the code from an article, then there is a "Add a Comment or Question" button at the bottom of that article, which causes an email to be sent to the author. They are then alerted that you wish to speak to them.
Posting this here relies on them "dropping by" and realising it is for them.

Context.InvokeAsynchronousTask(() =>
{
});
I have this code, its not getting called from the unit test project.
|
|
|
|
|
Well, without seeing the code for the unit test project, how do you expect anyone to give you any kind of usable answer?
|
|
|
|
|
Most likely the test finishes before the asynchronous task has a chance to execute.
You'll have to wait in the test for the completion of the asynchronous task. If you don't have a callback method that gets executed on completion you might just have to wait a few moments.
I usually use the ManualResetEvent with the WaitOne Method for such cases.
You can specify a timeout after which the execution should continue even if you don't receive a signal.

I am using WPF TestBlock control and activating a font which family id is Adolescence using Win32 API AddFontResource. This font is available on various document and also can be easily usable just adding the familyname on html web control. But for WPF TextBox it is not working just passing the family name.
I am using following code snippet.
<TextBlock Grid.Row="0" x:Name="SampleText" Text="{Binding
SampleText}" FontFamily="Adolescence" FontStyle="Normal"
FontSize="20"/>
I cannot put our fonts into windows font directory and also cannot add the directory path in FontFamily parameter and cannot add font into package.
I did googling a lot but could not found any solution. I also very curious to know why WPF is application is not able to detect Font while other application is able to detect the same.
Thanks in advance.

Some apps will "infer" a font based on a "name" and some properties; e.g. "Myriad Pro" and italic weight gives "Myriad Pro Italic", etc.
WPF needs the exact font name.
You should check the names of the fonts in the Control Panel "Fonts" app.
There are fonts (indicated with a little "stack" icon) that when clicked in Control Panel will yield other "sub-fonts" (which names one would use in WPF; besides the font properties).

Hello guys/gals,
Since a few months i have rather a real head desturbing issue :/
I have developed a plugin architecture that exists of a Host app and several plugins.
The host app basicly loads all the plugins availible, and allows any plugin to interact with the host, and vice versa.
Everything works fine when it comes to using methods/properties ect...accept for the events...
The events are used to send info to any asigned instance, including the plugins.
Whenever i assign the event inside plugin to recieve info from the host then i get the 'System.Reflection.TargetInvocationException'.
The exception is thrown whenever the host invokes the event that has been assigned from plugin instance.
Though i should mention that the event is used by the plugin AND the host.
They both should be revieving the plugin info...
I know ive used several events in a plugin system before, but that was the other way around.
The host was recieving info from plugin , witch works, just the other way arround seems to be a issue.
The Plugins are loaded by system.reflection as raw data and not as a file...
i did this because the plugins are stored in a custom container, compressed and encrypted.
Here is the manager interface (HOST):
public interface IPluginManager : IPluginBase
{
bool IsLoaded { get; }
Settings AppPreferences { get; }
ILogin Server { get; }
byte[] Signature { get; }
AppInfo[] Plugins { get; }
#region Events
event PluginRequestHandler PluginUpdate;
event PluginRequestHandler PluginInstall;
event PluginRequestHandler PluginRemove;
event PluginInstallHandler PluginsToInstall;
event PluginInstallHandler PluginsToUpdate;
event PluginInstallHandler PluginsToRemove;
event PluginHandler PluginActionChanged;
event PluginsHandler PluginsInstalled;
event PluginsHandler PluginsUpdated;
event PluginsHandler PluginsRemoved;
event EventHandler ManagerLoaded;
event EventHandler ManagerLoading;
event EventHandler ManagerDisposed;
#endregion
#region Methods
void LoadAsync();
void Dispose();
void RemovePluginAsync(AppInfo plugin);
bool RemovePlugin(AppInfo plugin);
void InstallPluginAsync(AppInfo plugin);
bool InstallPlugin(AppInfo plugin);
bool InstallNewPlugins();
void InstallNewPluginsAsync();
void MountPluginAsync(AppInfo info);
void UnmountPluginAsync(AppInfo info);
void EnableApp(AppInfo info);
void DisableApp(AppInfo info);
AppInfo[] GetOnlineApps();
#endregion
}
Here the code from plugin instance that init the Host event.
private void MainForm_Shown(object sender, EventArgs e)
{
if (Host != null && Host.PluginManager != null)
{
SCManager = Host.PluginManager;
SCManager.PluginActionChanged += X_PluginActionChanged;
Server = SCManager.Server;
if (Server == null)
{
var x = SCManager.Plugins.FirstOrDefault(t => t.Type == 1);
if (x != null)
SCManager.MountPluginAsync(x);
}
}
OnWindowShown(this);
}
Here is the Code that triggers the event:
protected virtual void OnPluginActionChanged(AppInfo info,PluginActionType action,Exception error = null,object param = null)
{
PluginHandler handler;
lock (_eventlock)
handler = _PluginActionChanged;
handler?.Invoke(this, info, action, error,param);
}
I really hope someone inhere can point me to the right direction, as i'm totally lost...
Thanks! and sorry for my bad english, let me know please if you guys/gals have any more question.

A TargetInvocationException occurs when an exception is thrown from a constructor. The stacktrace should show where it is trying to create the object that blows.
Bastard Programmer from Hell 
If you can't read my code, try converting it here[^]

MSDN says "The exception that is thrown by methods invoked through reflection. This class cannot be inherited."
so my take is that the issue occurs exactly at the
?.Invoke call.
What I don't understand is why the original poster doesn't just debug the code, and set the debugger to break on all exceptions - easy peasy.
The Plugins are loaded by system.reflection as raw data and not as a file...
i did this because the plugins are stored in a custom container, compressed and encrypted.
This sounds unnecessarily complicated - but I would first test uncompressing/decrypting them first, then go one step at a time, see when the issue occurs.
Best,
John
