Hello.
I'm trying to learn how to use windows forms in cTrader. Why in this example cBot does not perform "Print (" OnTick test ")".
Thank you in advance for your help.

Hi lw3010996,
if you remove this piece of code
thread.Join(); while (thread.IsAlive) System.Windows.Forms.Application.DoEvents();It should work fine.

I'm also trying to learn
I made a new bot and copied the code into it
Then I hit Edith With Visual Studio(2017)
Then I right-clicked it in Visual Studio and then Add -----> Windows Form
And I added a Windows Form to it
But I get an error when I hit Boild
Even delete what you said
please guide me

Hi mrha1000,
You need to change that line of code to the following
System.Windows.Forms.Application.Run(form);
since there is a conflict with the cBot's Application property.

Hello - A test template -> any pointer how to get this to work - see Call KBE. I have tried numerous approaches without success. Meaning - I can't get past errors calling KBE to test if it will work. Thank you.

Hi mrha1000,
You seem to be using an event handler without an event. Did you just copy and paste this from somewhere?

Did you just copy and paste this from somewhere? Fair question, but no.
I found numerous variation repeats of the below with regards C# Key Events
--------------------------------------------------------
Control.KeyPress Event
Definition
Namespace:
Assembly:
System.Windows.Forms.dll
-----------------------------------------------------
So went with
using System.Windows.Forms;
which first required invoking Manage References >> .NET Framework >> System.Windows.Forms
The rest is straight forward standard code.
My original request: A test template -> any pointer how to get this to work - see Call KBE. I have tried numerous approaches without success. Meaning - I can't get past errors calling KBE to test if it will work. Thank you.
C# examples merely illustrate calling KBE as KBE(sender, e); but this produces error -
You seem to be using an event handler without an event. ?
mmm ... yes..,.I thought I could call KBE and KBE would detect the relevant Key Events.

This will not happen. An event handler will be triggered only if you assign it to an event. Read more here.
