Accessing a forms controls from a class c# windows forms
Date : March 29 2020, 07:55 AM
wish of those help You could create an event from the class that stops the timer and raise it whenver you want that to happen. From the outer class (main form) after you instaciate the class you subscribe to that event and stop the timer in the handler. This is how you raise the event: class Class1
{
public event EventHandler StopTimer;
public void SomeMethod()
{
if (StopTimer != null)
StopTimer(this, EventArgs.Empty);
}
}
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
Class1 myClass = new Class1();
myClass.StopTimer += new EventHandler(myClass_StopTimer);
timer1.Enabled = true;
timer1.Start();
}
void myClass_StopTimer(object sender, EventArgs e)
{
timer1.Stop();
timer1.Enabled = false;
}
}

Boundary Class for each Function/Form or Group of Forms
Date : March 29 2020, 07:55 AM
Any of those help I saw some examples giving boundary class like LoginForm etc. That sounds correct at first glance. But in a real app where I have CRUD (4 functions at min) for each Model/Entity, isit more correct to group all functions for a single entity into 1 class? , It would be better to have something like below for boundary objects, FormService
+ insert(..)
+ update(..)
+ list(..)
+ delete(..).
TransactionService
+ invoke(...)

Windows forms - calling the same function from different forms
Date : March 29 2020, 07:55 AM
will help you Create a parent class that implements the method and derive your Forms from that parent class: class Foo : Form {
void LoadGraphics() {
this.BackColor = Graphics.GraphicsSettings.Default.BackgroundColor;
this.ForeColor = Graphics.GraphicsSettings.Default.ForegroundColor;
this.BackgroundImage = new Bitmap(Graphics.GraphicsResources.bg_small);
}
}
class YourForm : Foo {
void someFunction() {
LoadGraphics();
}
}

Keeping custom sign_up class and importing allauth forms in same forms.py file causing import errors
Date : March 29 2020, 07:55 AM
Does that help This happens because allauth tries to import the given module/class you specified as signup form in your settings.py in its account/forms.py. (See forms.py#L186 @ github) When you override other forms like ChangePasswordForm in your settings.py by importing allauth's account/forms.py, circular import happens because allauth has already imported your forms.py in its forms.py
