Note: Part of a series: C#: Accessing form members from another class and How to access form objects from another cs file in C#.
Hello,
The Idea is to notify the user using the memo when a packet is received/sent in a TCP Client.
After couple of fixes,the most suitable solution seemed to be this one
public string TextValue
{
set
{
this.Memo.Text += value + "\n";
}
}
That's how it's being called
var form = Form.ActiveForm as Form1;
if(form != null)
form.TextValue = "Test asdasd";
However,calling the code throws an exception ,because of Unsafe thread call.I found a solution at msdn,but I can't seem to acquire the method they've used there.
This is my remake,which doesn't work.
private void SetTextMemo(string txt)
{
if(this.Memo.InvokeRequired)
{
this.Invoke(SetTextMemo,txt); //error here
}
else
{
this.Memo.Text += txt + "\n";
}
}
errors:
Argument '1': cannot convert from 'method group' to 'System.Delegate'
Argument '2': cannot convert from 'string' to 'object[]'
Basically,I'm trying to access the Memo(or more likely said,add text to the memo) from another thread using Invoke.I never used it before,maybe that's why I misunderstand my mistake.
