I have a GUI that is linked to several Sensors through COM-Port. I have a Datahandler that makes sure that the received and sent packages have the correct size and content. And then i have a SensorContainer containing all Sensors, firing an event whenever a new sensor is added!
My problem is now:
I need a method, that can initialize all sensors with one click.
And i just cant do it. If I initialize them one by one, it works, but all in one method doesnt work.
My idea is that the packages get mixed and the handler doesnt accept the sensors anymore for initialization. So i tried to make the method wait for the first sensor to be initialized and the proceed, but i have no clue how!
I tried a few things with mulitthreading, but im not really experienced in that field and it didnt work out in the end anyway...

We have a Till Software which also works with restaurants built on .NET (C#) and Firebird DB. We are having a strange problem recently, the items in an order are duplicating themselves when we go back to the order.
Strangely it's not the case always. It's happening only sometimes. I tried to figure out under what conditions it's happening but it's so random that it doesn't happen for a couple of days and then start duplicating items for the next two days.
The software is so huge that I don't know what code snippets to even post. As it's not happening always and is random I guess it doesn't have to do with the code but with Firebird DB maybe.
The other thing I wanted to mention is that we had a Firebird DB built on a 32-bit machine and when we tried to put it on a 64 - bit machine it didn't work. So, we had to take a backup of the DB on a 32-bit machine and restore it on a 64-bit machine and it worked with the software. I'm thinking does that have something to do with it? but we have another user on 32-bit with no conversion and it's the same case for him as well.
I'll really appreciate any help or guidance on this.

I'm trying to make a simple script that saves a text from an input field, like a "remember me" check box. It works fine on the editor. It saves, it logs correctly, it loads fine. But when I build the scene it doesn't work, it's like PlayerPrefs never saves anything. Anyone knows why?
public Toggle rememberMe;
public InputField fieldMail;
public InputField fieldPassword;
private string mail;
private string password;
private int rememberMeChecked = 0;
private bool justChecked = false;

}

just export your code to the view model and set the view model as binding context of the Page. For example in the constructor:
//In the code behind
PageViewModel viewModel;
public Page()
{
this.BindingContext = viewModel = new PageViewModel();
//...
}
The ViewModel should implement INotifyPropertyChanged.
(Functions which are triggered by events have to stay in the code behind and access the view model through the ViewModel Property)
I created Scintilla Popup for textbox to show autocomplete :
this.hWnd = CreateWindowEx(
0, "Scintilla", "",
WS_CHILD | WS_VISIBLE | WS_TABSTOP | WS_CLIPCHILDREN | 0x00002000,
x, y, textbox1.ClientSize.Width, textbox1.ClientSize.Height, textbox1.Handle, (IntPtr)0, (IntPtr)0, (IntPtr)0);
and in custom textbox, i overriden WndProc :
protected override void WndProc(ref Message m)
{
}
I build project in x86, and each time i call "SendMessage", the autocomplete showed on textbox and WndProc called. But when i build project in x64, only autocomplete showed and WndProc not called. Please, help me ??
Thanks.

how can i solve this problem?
thanks in advance
Had the same issue.
Open the StreamingPlayback.cs file
Change the variable
int bufferSize = 128 * 1024
Into
int bufferSize = 128 * 128
Or try other sizes..
It worked for me
